Executive Compensation | Just Tax

§ 409A Coverage and Plan Aggregation (Notice 2005-1; Reg. § 1.409A-1(c))

This checklist guides the practitioner through determining whether an arrangement constitutes nonqualified deferred compensation subject to IRC § 409A, identifying the applicable plan aggregation category, and assessing the consequences of plan aggregation for compliance failures. Use it when analyzing executive compensation arrangements, severance agreements, equity awards, and other potentially deferred compensation.

Step 1. The § 409A Statutory Framework and Penalty Structure

"If at any time during a taxable year a nonqualified deferred compensation plan fails to meet the requirements of paragraphs (2), (3), and (4), or is not operated in accordance with such requirements, all compensation deferred under the plan for the taxable year and all preceding taxable years shall be includible in gross income for the taxable year to the extent not subject to a substantial risk of forfeiture and not previously included in gross income." (IRC § 409A(a)(1)(A)(i))

• The statutory penalty structure is three-tiered and punitive. § 409A imposes immediate income inclusion, a 20% additional tax, and premium interest on all deferred amounts affected by a plan failure.
  • Tier 1. Income inclusion. All deferred amounts under the failed plan for the taxable year and all preceding taxable years become includible in gross income to the extent not subject to a substantial risk of forfeiture and not previously included. (IRC § 409A(a)(1)(A)(i))
  • Tier 2. 20% additional tax. The participant must pay an additional tax equal to 20% of the compensation includible under Tier 1. This tax is not deductible and is in addition to regular income tax. (IRC § 409A(a)(1)(B))
  • Tier 3. Premium interest tax. Interest is imposed on the underpayment that would have resulted had the deferred amounts been includible in the year first deferred (or first no longer subject to SRF), computed at the federal underpayment rate plus 1% compounded daily. (IRC § 409A(a)(1)(B)(ii))
• The income inclusion trigger is participant-specific. Compensation is includible in gross income under § 409A(a)(1)(A)(i) if a nonqualified deferred compensation plan fails to meet the specified requirements during any taxable year of the participant. Compensation is includible under § 409A(a)(1)(A)(ii) if the employer fails to meet the § 409A(a)(3) prohibition on acceleration of payments. (§ 409A(a)(1)(A)(i)-(ii))
  • The inclusion applies only with respect to the participant for whom the failure occurs. A plan failure affecting one participant does not trigger income inclusion for other participants who have not experienced a failure with respect to their own deferred amounts. (Treas. Reg. § 1.409A-4(a)(1))
  • The phrase "with respect to whom the failure relates" means that the participant must have a personal stake in the failure. If a plan document contains an impermissible acceleration provision, the failure relates to every participant whose plan includes that provision, even if no payment has actually been accelerated. (Treas. Reg. § 1.409A-4(a)(1))
• The 20% additional tax applies to the full includible amount. The penalty under § 409A(a)(1)(B) is calculated as 20% of the compensation that is required to be included in gross income under § 409A(a)(1)(A). (§ 409A(a)(1)(B))
  • This additional tax is not deductible. It increases the participant's total tax liability without offset.
  • The 20% tax is imposed on the full includible amount even if the participant is in a lower regular tax bracket. A participant in the 12% ordinary income bracket who incurs a § 409A failure still pays 20% on the includible amount plus regular income tax, resulting in an effective marginal rate of 32% before premium interest. (IRC § 409A(a)(1)(B))
• The premium interest tax applies at the underpayment rate plus one percentage point. Interest is imposed on the underpayment that would have resulted had the deferred amounts been includible in gross income for the taxable year in which first deferred or, if later, the first taxable year in which such amounts are not subject to a substantial risk of forfeiture. (§ 409A(a)(1)(B)(ii))
  • The interest rate is the federal underpayment rate determined under § 6621(a)(2) plus 1%. The rate is compounded daily from the date the compensation should have been included in income through the date of actual inclusion. (§ 409A(a)(1)(B)(ii))
  • Interest is computed from the earlier of (i) the taxable year in which the amount was first deferred, or (ii) the first taxable year in which the amount is no longer subject to a substantial risk of forfeiture. For amounts that vest immediately upon deferral, the interest period runs from the deferral year. For amounts with multi-year vesting, the interest period may begin in a later year. (§ 409A(a)(1)(B)(ii))
• The four principal operational requirements create the compliance framework. Every NQDC arrangement must satisfy four statutory conditions to avoid the § 409A penalty regime.
  • Initial deferral elections. The plan must require that initial elections to defer compensation be made no later than the close of the preceding taxable year or, in the case of performance-based compensation, no later than six months before the end of the performance period. (§ 409A(a)(4)(A)-(B))
  • Permissible payment events. Distributions may occur only upon separation from service, a predetermined date, a change in control, death, disability, or the occurrence of an unforeseeable emergency. (§ 409A(a)(2)(A))
  • Prohibition on acceleration. The plan must prohibit the acceleration of the time or schedule of any payment. (§ 409A(a)(3))
  • Subsequent deferral elections. A subsequent election must defer the payment for at least five additional years and must be made at least twelve months before the date the payment would otherwise have been made. (§ 409A(a)(4)(C))
• Legislative context. Congress enacted § 409A as part of the American Jobs Creation Act of 2004 in response to the Enron bankruptcy, in which executives accelerated payment of approximately $53 million in deferred compensation before the company's collapse.
  • The Senate Finance Committee report documented that Enron's top 126 executives received $53 million in accelerated deferred compensation payments in the months before the bankruptcy filing, exploiting the absence of rules restricting acceleration of NQDC payments. (S. Rep. No. 108-192, at 69-70 (2003))
  • The AJCA 2004 legislative history reflects congressional intent to impose strict rules on deferred compensation to prevent executives from securing payments ahead of corporate creditors and to eliminate preferential treatment of executive pay in insolvency situations. (AJCA 2004, Pub. L. No. 108-357, § 885)
• Effective date. § 409A applies to amounts deferred in taxable years beginning after December 31, 2004. Amounts deferred before that date are generally grandfathered if not materially modified. (§ 409A(c)(1)(A)) (Treas. Reg. § 1.409A-6(a))
  • The December 31, 2004 cutoff is based on the date the legally binding right to deferred compensation arises, not the date of payment. An amount earned before 2005 but payable after 2005 is grandfathered if the right arose before January 1, 2005 and the arrangement has not been materially modified.
  • Material modification trap. A material modification of a pre-2005 arrangement causes the modified arrangement to be treated as a new plan subject to § 409A in full. A modification is material if it changes the time or form of payment, the amount of compensation, or the conditions for payment, except for changes required by law or that conform the plan to § 409A requirements. (Treas. Reg. § 1.409A-6(a))
• CAUTION. The participant bears the penalty, not the employer. The penalty regime is triggered by the failure of the PLAN, not merely the failure of the employer to comply.
  • A participant can be subject to full § 409A penalties even where the employer made an inadvertent operational error. The income inclusion, 20% additional tax, and premium interest are personal tax liabilities of the participant, not the employer.
  • Employers commonly provide tax gross-ups or indemnification for § 409A failures in employment agreements and change-in-control agreements. Practitioners should verify whether such indemnification provisions exist and whether they cover all three penalty components (income inclusion, 20% tax, and premium interest).

Step 2. The Definition of Nonqualified Deferred Compensation Plan

"The term 'nonqualified deferred compensation plan' means any plan that provides for the deferral of compensation, other than a qualified employer plan or any bona fide vacation leave, sick leave, compensatory time, disability pay, or death benefit plan." § 409A(d)(1).

• The regulatory definition is broad and functional. Treas. Reg. § 1.409A-1(a)(1) defines a nonqualified deferred compensation plan as any "plan" (as defined in § 1.409A-1(c)) that provides for the "deferral of compensation" (as defined in § 1.409A-1(b)). (Treas. Reg. § 1.409A-1(a)(1))
  • Neither the statute nor the regulations use the word "nonqualified" as a substantive limitation. A plan is "nonqualified" simply because it is not one of the enumerated excluded plans.
  • The definition looks to substance over form. An arrangement labeled as a bonus, retention payment, equity award, or expense reimbursement may still constitute a nonqualified deferred compensation plan if it provides for a legally binding right to compensation in a later taxable year.
• The nine qualified employer plan exclusions remove arrangements from § 409A coverage. Treas. Reg. § 1.409A-1(a)(2) excludes from the definition of nonqualified deferred compensation plan any plan that meets the requirements of the following statutory provisions. (Treas. Reg. § 1.409A-1(a)(2))
  • A trust described in § 401(a) qualified under § 401(a) (including a governmental plan under § 414(d)).
  • A plan described in § 403(a) (qualified annuity plans of employers).
  • An annuity contract described in § 403(b) (tax-sheltered annuities).
  • A simplified employee pension described in § 408(k) (SEPs).
  • A simple retirement account described in § 408(p) (SIMPLE IRAs).
  • A trust described in § 501(c)(18) (certain pre-June 25, 1959 employee pension trusts).
  • An eligible deferred compensation plan described in § 457(b) (governmental and tax-exempt eligible plans only). Note that § 457(f) ineligible plans ARE subject to § 409A.
  • A plan described in § 415(m) (qualified foreign plans).
  • A trust described in ERISA § 1022(i)(1) or (2) (certain Puerto Rican and foreign retirement plans subject to certain conditions).
• The foreign plan exclusions remove certain cross-border arrangements. Treas. Reg. § 1.409A-1(a)(3) excludes five categories of foreign arrangements from the definition. (Treas. Reg. § 1.409A-1(a)(3))
  • A plan providing compensation solely due to the deferral of amounts that would be excluded from gross income under an applicable income tax treaty.
  • A plan providing compensation solely to nonresident aliens for services performed outside the United States that are excluded from U.S. gross income under § 872(b)(8).
  • A broad-based foreign retirement plan (as defined in § 1.409A-1(a)(3)(iii)).
  • A plan providing compensation to a nonresident alien solely due to deferral of amounts excluded from gross income under § 861(a)(3)(providing an exception for income from certain annuities and remuneration for services performed outside the United States).
  • A plan providing compensation solely due to the deferral of amounts under a totalization agreement between the United States and a foreign government.
• The welfare benefit exclusions remove certain non-retirement benefits. Treas. Reg. § 1.409A-1(a)(4) excludes seven categories of arrangements from the definition. (Treas. Reg. § 1.409A-1(a)(4))
  • A bona fide vacation leave program.
  • A bona fide sick leave program.
  • A bona fide compensatory time plan.
  • A bona fide disability pay plan.
  • A bona fide death benefit plan (including life insurance).
  • A medical savings account described in § 220 (Archer MSA).
  • A health savings account described in § 223 (HSA).
  • A health reimbursement arrangement (HRA) that meets the requirements of Notice 2002-45 and Notice 2002-69.
• TRAP. Welfare benefit exclusions require bona fide plans. An arrangement that pays a lump sum in lieu of vacation or sick leave at termination of employment may not qualify as a bona fide vacation or sick leave plan.
  • A plan is bona fide only if it pays benefits based on accrued, unused leave balances calculated under an objective formula. A payment that is a formulaic termination benefit unrelated to actual accrued leave (e.g., a flat number of weeks based on years of service) is not a bona fide vacation or sick leave plan and may be recharacterized as deferred compensation subject to § 409A. (Treas. Reg. § 1.409A-1(a)(4))
  • The consequences of failed bona fide status are severe. If the arrangement is recharacterized as an NQDC plan, all deferred amounts become immediately includible in income, and the participant is subject to the 20% additional tax and premium interest unless the arrangement satisfies all § 409A(a) operational requirements from inception. (IRC § 409A(a)(1)(A)(i))
• The anti-circumvention authority preserves the Commissioner’s power to recharacterize. If the principal purpose of an arrangement is to circumvent § 409A, the Commissioner may treat the arrangement as providing for the deferral of compensation regardless of its form. (Treas. Reg. § 1.409A-1(a)(5))
  • The principal purpose standard is a facts-and-circumstances test. The Commissioner looks to whether the arrangement was structured with a principal purpose of obtaining tax deferral while avoiding § 409A's substantive requirements.
  • Circumvention indicators include structuring an arrangement to fall just outside the short-term deferral window, labeling deferred compensation as a nondeferred payment type (e.g., "reimbursement" or "loan"), fragmenting a single deferred amount across multiple documents to avoid aggregation, and incorporating nullification clauses that purport to void the arrangement if § 409A applies.
• The retroactive change rule fixes characterization at inception. Treas. Reg. § 1.409A-1(b)(5) provides that the determination of whether a plan provides for a deferral of compensation is made at the time the service provider obtains a legally binding right to the compensation. A subsequent change in the plan, or a change in the legally binding right, may alter the characterization, but the original characterization controls for amounts already deferred. (Treas. Reg. § 1.409A-1(b)(5))
  • CAUTION. An employer cannot retroactively "clean up" an arrangement by amending it after the legally binding right has arisen. If the arrangement was a deferred compensation plan when the right arose, it remains subject to § 409A for that compensation even if later modified.
  • EXAMPLE. An employer establishes an unfunded deferred bonus plan for an executive in 2022. In 2024, the employer amends the plan to add a rabbi trust and modifies the payment timing. The amendment does not retroactively remove the § 409A obligations that attached in 2022. The amounts deferred in 2022 remain subject to § 409A based on the terms in effect when the legally binding right arose. (Treas. Reg. § 1.409A-1(b)(5))

Step 3. The Definition of Deferral of Compensation

"A plan provides for the deferral of compensation with respect to a service provider if the service provider has a legally binding right during a taxable year to compensation that has not been actually or constructively received and that is payable in a later taxable year." Treas. Reg. § 1.409A-1(b)(1).

• The general rule requires a legally binding right to later-paid compensation. A plan provides for the deferral of compensation if the service provider has a legally binding right during one taxable year to compensation that is not actually or constructively received in that year and is payable in a subsequent taxable year. (Treas. Reg. § 1.409A-1(b)(1))
  • Constructive receipt is determined under the rules of § 451 and Treas. Reg. § 1.451-2. If the service provider could have received the compensation upon demand but chose not to, constructive receipt may apply even absent actual receipt.
  • The determination is made on a participant-by-participant basis. An arrangement may provide for the deferral of compensation for one service provider but not another, depending on whether each has a legally binding right.
• The negative discretion exception removes arrangements where the employer retains unfettered authority to reduce or eliminate compensation. A service provider does not have a legally binding right to compensation if the compensation may be reduced unilaterally or eliminated by the service recipient or another person prior to the date the compensation is actually or constructively received. (Treas. Reg. § 1.409A-1(b)(1))
  • The availability of negative discretion must be genuine. The regulations set out three exceptions where purported negative discretion will be disregarded.
  • Negative discretion must exist at the time the legally binding right would otherwise arise. A reservation of discretion that is added after the right has vested does not retroactively remove the deferral-of-compensation characterization. (Treas. Reg. § 1.409A-1(b)(1))
• Exception 1. Discretion that is conditioned or lacks substantive significance does not negate the legally binding right. If the service recipient’s discretion to reduce or eliminate compensation is available only upon the occurrence of a condition, or if the discretion lacks substantive significance, the service provider is treated as having a legally binding right. (Treas. Reg. § 1.409A-1(b)(1))
  • A condition means that the discretion is not absolute and unconditional. If the employer can reduce compensation only upon specified events (e.g., failure to meet performance goals), the condition does not eliminate the legally binding right because the participant has a right to the compensation if the condition does not occur.
  • Discretion lacks substantive significance if the standards for exercise are so objective or constrained that the employer effectively cannot exercise the discretion in a meaningful way.
• Exception 2. Family member or controlled-entity discretion lacks substantive significance. Negative discretion retained by a person who is a family member (as defined in § 267(c)(4), including a spouse) of the service provider, or by an entity controlled by the service provider or a family member, is treated as lacking substantive significance. (Treas. Reg. § 1.409A-1(b)(1)) (§ 267(c)(4))
  • § 267(c)(4) defines family members as brothers and sisters (whether by whole or half blood), spouse, ancestors, and lineal descendants. The inclusion of "spouse" in the § 267(c)(4) definition is expressly referenced in the § 409A regulations.
  • An entity is controlled by the service provider if the service provider owns more than 50% of the entity’s voting power or value. (Treas. Reg. § 1.409A-1(b)(1))
• Exception 3. Objective plan terms and substantial risk of forfeiture do not count as negative discretion. A plan term providing that compensation is subject to a nondiscretionary, objective substantial risk of forfeiture does not constitute negative discretion. (Treas. Reg. § 1.409A-1(b)(1))
  • If the plan specifies in advance that compensation will be forfeited upon the occurrence of certain objective conditions (e.g., termination for cause, failure to compete, failure to satisfy a performance condition), and the forfeiture condition constitutes a substantial risk of forfeiture within the meaning of Treas. Reg. § 1.409A-1(d), the forfeiture provision does not create negative discretion. The service provider still has a legally binding right to the compensation if the condition is not triggered.
  • The substantial risk of forfeiture must be genuine. The regulations provide detailed standards for what constitutes a substantial risk of forfeiture, including the requirement that the employer have a substantial risk of losing the compensation and that the condition relate to future services or business activities.
• Nonvested deferred compensation is still deferred compensation subject to § 409A(a) requirements. An amount subject to a substantial risk of forfeiture constitutes deferred compensation even though it is nonvested. The § 409A(a) requirements (initial elections, permissible payment events, prohibition on acceleration, and subsequent elections) apply to nonvested amounts from the date the legally binding right arises. (Treas. Reg. § 1.409A-1(b)(1))
  • TRAP. Practitioners sometimes assume that because an amount is subject to forfeiture, § 409A does not apply until vesting. This is incorrect. The § 409A(a) distribution rules must be satisfied from inception, and any impermissible payment terms in a nonvested arrangement are subject to the full penalty regime.
  • A nonvested arrangement must specify a permissible payment event and comply with the initial deferral election requirements at the time the legally binding right arises, even though the participant may forfeit the right before payment ever becomes due. The fact that forfeiture is possible does not eliminate the need for § 409A-compliant plan terms from day one. (Treas. Reg. § 1.409A-1(b)(1))
• The mere promise to pay in a later year is sufficient. The regulations make clear that a legally binding right to compensation payable in a later year satisfies the deferral-of-compensation definition even if no formal plan document exists and even if the arrangement is unfunded. (Treas. Reg. § 1.409A-1(c)(1))
  • EXAMPLE. An employer orally promises an executive a $1 million bonus payable three years after the end of the year in which the bonus is earned. No written agreement exists. No trust or rabbi trust is established. The executive has a legally binding right to compensation payable in a later taxable year. The arrangement is a nonqualified deferred compensation plan subject to § 409A.
  • TRAP. The absence of a written plan document does not exempt an arrangement from § 409A. In fact, the absence of a written plan causes a separate written plan requirement failure under Treas. Reg. § 1.409A-1(c)(3), which triggers income inclusion, the 20% additional tax, and premium interest on the deferred amounts under that specific arrangement. (Treas. Reg. § 1.409A-1(c)(3)(viii))
• Certain short-term deferrals are excluded. Treas. Reg. § 1.409A-1(b)(4) provides a critical exclusion for short-term deferrals. Amounts are not treated as deferred compensation if the service provider actually or constructively receives the payment no later than the later of (i) the 15th day of the third month after the end of the taxable year in which the right to the payment is no longer subject to a substantial risk of forfeiture, or (ii) the 15th day of the third month after the end of the taxable year of the service recipient in which the right is no longer subject to a substantial risk of forfeiture. (Treas. Reg. § 1.409A-1(b)(4)(i)(A))
  • The short-term deferral exception is the most frequently relied-upon exclusion in practice. Practitioners must track both the service provider’s taxable year and the service recipient’s taxable year when applying the rule.
  • CAUTION. If payment under the plan MAY be made after the short-term deferral deadline, the arrangement IS subject to § 409A even if payment is actually made within the short-term period. The test looks to plan terms at the time the legally binding right arises, not to when payment is actually made. (Treas. Reg. § 1.409A-1(b)(4)(i)(A))

Step 4. The Definition of Plan and Its Expansive Scope

"The term 'plan' includes any agreement, method, program, or other arrangement, including an agreement, method, program, or other arrangement that applies to one person or individual." Treas. Reg. § 1.409A-1(c)(1).

• The regulatory definition of "plan" is extraordinarily broad. Treas. Reg. § 1.409A-1(c)(1) defines "plan" to include any agreement, method, program, or other arrangement, expressly including arrangements that apply to only one person or individual. (Treas. Reg. § 1.409A-1(c)(1))
  • The definition captures oral agreements, handshake deals, and informal understandings. A written document is not required for an arrangement to constitute a plan.
  • No ERISA plan requirement exists. An arrangement need not be a "plan" within the meaning of ERISA § 3(3) to be a plan under § 409A.
• Single-person arrangements count. The regulation expressly states that an arrangement covering a single service provider constitutes a plan. (Treas. Reg. § 1.409A-1(c)(1))
  • A bespoke employment agreement with a CEO providing for severance payments over 24 months is a "plan" under § 409A even though it applies to one person.
  • A phantom stock award to a single executive is a "plan" under § 409A.
• A plan may be adopted unilaterally or by agreement. The service recipient may establish a plan unilaterally, or the plan may be the product of negotiation between the service recipient and the service provider. (Treas. Reg. § 1.409A-1(c)(1))
  • An employer policy manual provision that creates a legally binding right to deferred compensation constitutes a plan even if employees did not negotiate the terms.
  • A board resolution establishing a supplemental executive retirement plan for selected executives constitutes a plan even if adopted without the executives’ individual consent.
• Each service provider is treated as having a separate plan. The regulations provide that for purposes of § 409A, all arrangements subject to § 409A between a service recipient (or any member of the same controlled group) and a service provider are treated as if maintained as a single plan for that service provider. (Treas. Reg. § 1.409A-1(c)(1))
  • This aggregation rule operates at the service provider level. All arrangements between the employer and one executive are treated as one plan for that executive.
  • This is distinct from the category-based aggregation rules in § 1.409A-1(c)(2)(i), which apply across service providers and subdivide plans into nine categories.
• Nullification provisions are disregarded. A plan term providing that a benefit is payable only if § 409A does not apply, or that the benefit will be forfeited or reduced if § 409A applies, is disregarded. (Treas. Reg. § 1.409A-1(c)(1))
  • An employer cannot avoid § 409A coverage by including a clause stating "this arrangement is not intended to be a deferred compensation plan" or "if this arrangement is subject to § 409A, no benefits will be paid."
  • A plan term that purports to condition payment on § 409A not applying is treated as a nullity. The compensation remains deferred compensation subject to § 409A, and the nullification clause itself is evidence of a potential anti-circumvention intent under Treas. Reg. § 1.409A-1(a)(5).
• Common arrangement types that constitute plans. Practitioners should scrutinize the following arrangements for § 409A coverage.
  • Employment agreements providing for deferred compensation, retention payments, or severance.
  • Severance agreements and separation agreements with deferred payment schedules.
  • Change-in-control agreements with single-trigger or double-trigger payments.
  • Equity awards including stock options, stock appreciation rights, restricted stock units, phantom stock, and performance share units. (Note that stock options and SARs are subject to specific valuation and timing rules under Treas. Reg. § 1.409A-1(b)(5)(i)(A) and may or may not provide for deferral of compensation depending on whether the exercise price equals or exceeds fair market value.)
  • Bonus deferral arrangements allowing executives to defer annual or long-term incentive bonuses.
  • Salary reduction agreements permitting executives to defer base salary.
  • Supplemental executive retirement plans (SERPs) providing unfunded nonqualified retirement benefits.
  • Deferred compensation plans maintained by tax-exempt organizations and governmental entities (which are subject to § 409A unless excluded under § 457(b) or another exception).
• TRAP. Impermissible payment events cause immediate § 409A failure. An arrangement that provides for payment upon a condition that is NOT one of the six permissible payment events under § 409A(a)(2)(A) is a § 409A failure even if the arrangement is otherwise well-drafted.
  • The six permissible payment events are exhaustive. No other payment trigger qualifies. Common impermissible events include payment upon (i) an initial public offering, (ii) a change in duties without separation, (iii) a liquidity event that is not a § 409A change in control, and (iv) a performance goal that is not tied to one of the six statutory events. (§ 409A(a)(2)(A)) (Treas. Reg. § 1.409A-3(a))
  • Practitioners must confirm that every payment trigger in every arrangement falls within one of the six statutory events. Review each arrangement's payment provisions against the statutory list, and document the mapping of each trigger to its corresponding permissible event. (§ 409A(a)(2)(A))

Step 5. The Plan Aggregation Rules

Step 5A. The Nine Plan Categories Under § 1.409A-1(c)(2)(i)

"All plans of a service recipient in which a service provider participates that are account balance plans under which amounts are deferred pursuant to an election made by the service provider are treated as a single plan. All plans of a service recipient in which a service provider participates that are account balance plans under which amounts are deferred other than pursuant to an election made by the service provider (including a matching contribution) are treated as a single plan." Treas. Reg. § 1.409A-1(c)(2)(i)(A)-(B).

• The category-based aggregation rule is mandatory. Treas. Reg. § 1.409A-1(c)(2)(i) requires that all plans of a service recipient in which a service provider participates within the same of nine categories be treated as a single plan for purposes of § 409A. (Treas. Reg. § 1.409A-1(c)(2)(i))
  • The aggregation rule applies regardless of whether the plans are formally separate documents. Two distinct plan documents, two appendixes to one document, or two informal arrangements all fall within the rule if they belong to the same category.
  • The aggregation rule applies only to plans of the SAME service recipient. Plans of different employers within a controlled group are subject to the controlled group rules of § 1.409A-1(h).
  • The rule applies per service provider. Aggregation is determined with respect to each service provider individually based on which plans that particular service provider participates in.
• Category (A). Elective deferral account balance plans. All plans of a service recipient in which a service provider participates that are account balance plans under which amounts are deferred pursuant to an election made by the service provider are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(A))
  • An "account balance plan" is defined in Treas. Reg. § 1.409A-1(c)(2)(i)(A) as a plan under which the amount payable is based solely on the value of a hypothetical or actual account maintained for the service provider. The account is credited with contributions, earnings, and losses.
  • This category captures elective deferrals under supplemental executive retirement plans, deferred compensation plans, and similar arrangements where the participant affirmatively elects to defer.
• Category (B). Nonelective account balance plans. All plans of a service recipient in which a service provider participates that are account balance plans under which amounts are deferred other than pursuant to an election made by the service provider (including a matching contribution) are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(B))
  • Employer contributions to a SERP or deferred compensation plan that are not contingent on a participant election fall into this category.
  • Matching contributions are expressly treated as nonelective for aggregation purposes. Even if a matching contribution is triggered by a participant elective deferral into another plan, the matching contribution itself is aggregated in Category (B), not Category (A). (Treas. Reg. § 1.409A-1(c)(2)(i)(B))
• Category (C). Nonaccount balance plans. All nonaccount balance plans of a service recipient in which a service provider participates are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(C))
  • A "nonaccount balance plan" is a plan under which the amount payable is not based on an account balance. The amount is determined by a formula that does not reference a hypothetical account, such as a defined benefit formula, a percentage of final pay, or a fixed dollar amount.
  • Traditional SERPs providing a fixed annual benefit, final-average-pay formulas, and career-average-pay formulas are nonaccount balance plans.
• Category (D). Separation pay plans. All separation pay plans of a service recipient in which a service provider participates are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(D))
  • A "separation pay plan" is a plan providing payments upon or following an involuntary separation from service or pursuant to a window program. (Treas. Reg. § 1.409A-1(c)(2)(i)(D))
  • Separation pay plans are distinguished from general account balance or nonaccount balance plans by their payment trigger. If the only or primary payment event is involuntary separation, the plan falls in this category.
• Category (E). In-kind benefits and reimbursement plans. All plans of a service recipient in which a service provider participates that provide in-kind benefits or reimbursements are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(E))
  • This category includes plans providing taxable in-kind benefits, such as continued use of a company car or office after retirement.
  • It also includes reimbursement arrangements where the employer reimburses expenses incurred by the service provider, to the extent the reimbursement is taxable.
• Category (F). Split-dollar plans. All split-dollar life insurance arrangements of a service recipient in which a service provider participates are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(F))
  • This category captures all split-dollar arrangements under the economic benefit regime or the loan regime to the extent they provide deferred compensation.
  • Split-dollar arrangements that are fully taxed under the economic benefit regime in the year the benefits are provided (with no deferral of compensation) are not subject to § 409A and do not fall into this category. Only arrangements that defer the recognition of compensation are aggregated here. (Treas. Reg. § 1.409A-1(c)(2)(i)(F))
• Category (G). Foreign earned income plans. All plans of a service recipient in which a service provider participates that provide compensation attributable to foreign earned income (as defined in § 911(b)) are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(G))
  • This category applies to arrangements for employees working outside the United States whose compensation qualifies for the § 911 foreign earned income exclusion.
  • The § 911(b) definition of foreign earned income includes amounts received from sources within a foreign country that constitute earned income (wages, salaries, professional fees). Amounts exceeding the § 911(b)(2)(D)(i) annual exclusion limit ($126,500 for 2024) are included in gross income and may be deferred under a Category (G) plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(G)) (§ 911(b)(2)(D)(i))
• Category (H). Stock right plans. All plans of a service recipient under which stock rights (as defined in Treas. Reg. § 1.409A-1(b)(5)(i)(A)) are granted to a service provider are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(H))
  • "Stock rights" include stock options and stock appreciation rights that are subject to § 409A because the exercise price may be less than fair market value, the intrinsic value exceeds the spread at grant, or other § 409A conditions are not met.
  • Stock rights that meet the requirements of § 1.409A-1(b)(5)(i)(A) are excluded from the definition of deferred compensation and do not fall into this category.
• Category (I). Catch-all for any other plans. All other plans of a service recipient in which a service provider participates are treated as a single plan. (Treas. Reg. § 1.409A-1(c)(2)(i)(I))
  • This residual category captures any arrangement providing deferred compensation that does not fit into Categories (A) through (H).
  • Practitioners should scrutinize novel or hybrid compensation arrangements that combine features of multiple categories. If the arrangement cannot be clearly classified in Categories (A) through (H), it falls into Category (I) and is aggregated with all other Category (I) plans. Document the classification analysis to support the position taken. (Treas. Reg. § 1.409A-1(c)(2)(i)(I))

Step 5B. The Dual Status and Director Aggregation Rules

• Employee and independent contractor plans are NOT aggregated. Plans in which a service provider participates as an employee are not aggregated with plans in which the same service provider participates as an independent contractor. (Treas. Reg. § 1.409A-1(c)(2)(ii))
  • The service provider is treated as participating in two separate universes of plans, one for employee arrangements and one for independent contractor arrangements.
  • The employee-versus-independent-contractor determination follows common law standards. A service provider who transitions from employee to independent contractor (or vice versa) must have a genuine change in status. The same compensation arrangement cannot be shifted between categories to manipulate the aggregation rules. (Treas. Reg. § 1.409A-1(c)(2)(ii))
• Employee-director arrangements are not aggregated with non-employee director arrangements. An employee who also serves as a director is treated as having a separate plan for director arrangements if the director arrangements are substantially similar to arrangements provided to non-employee directors. (Treas. Reg. § 1.409A-1(c)(2)(ii))
  • The "substantially similar" standard compares the terms of the arrangement to those offered to directors who are not employees of the service recipient. If the arrangement is comparable in form and benefit level, it is not aggregated with employee plans.
  • If the director arrangement is NOT substantially similar to non-employee director arrangements, it is treated as an employee plan and aggregated with other employee plans.
• Director and independent contractor plans ARE aggregated. Plans in which a service provider participates as a director are aggregated with plans in which the same service provider participates as an independent contractor. (Treas. Reg. § 1.409A-1(c)(2)(ii))
  • This is a TRAP for service providers who serve as both directors and consultants. Their director compensation arrangements and consulting arrangements in the same category are treated as a single plan.
  • A consulting agreement that provides deferred compensation payable upon termination of the consulting relationship is aggregated with director deferred compensation in the same category. An operational failure in the consulting agreement taints the director arrangement and vice versa. (Treas. Reg. § 1.409A-1(c)(2)(ii))
• Separation from service consequence for dual-status service providers. A service provider who is both an employee and a director (or both a director and an independent contractor) must separate from service in BOTH roles for a separation from service to occur under § 409A(a)(2)(A)(i). (Treas. Reg. § 1.409A-1(c)(2)(ii))
  • EXAMPLE. An executive serves as an employee and as a board director. The executive retires from employment but remains on the board. No separation from service has occurred for § 409A purposes because the executive continues to provide services as a director. Payments triggered by separation from service cannot commence until the executive resigns from the board or ceases to provide services in the director capacity.
  • This rule prevents dual-status service providers from manipulating the separation-from-service trigger by terminating one role while continuing another.

Step 5C. Account Balance Plan Subdivision

• Elective and nonelective account balance plans are subdivided only if amounts can be separately identified. The subdivision of account balance plans into Category (A) (elective) and Category (B) (nonelective) applies only if the elective and nonelective portions can be separately identified. (Treas. Reg. § 1.409A-1(c)(2)(iii))
  • If a single plan document provides for both elective deferrals and employer nonelective contributions, and the plan maintains separate bookkeeping accounts tracking each source, the elective and nonelective portions are treated as separate plans for aggregation purposes.
  • If the plan does not maintain separate tracking and the elective and nonelective amounts are commingled in a single account, the entire plan must be categorized based on its predominant character or allocated as described in Step 5D.
• Matching contributions are treated as nonelective. A matching contribution made in connection with an elective deferral is treated as a nonelective amount and falls into Category (B), even though the matching contribution would not have been made absent the elective deferral. (Treas. Reg. § 1.409A-1(c)(2)(iii))
  • This is a critical rule for plans that match elective deferrals. The match is not aggregated with the elective deferral but is instead aggregated with all other nonelective account balance plans.
  • A nonelective employer contribution that is contingent on the participant's elective deferral into a different plan (e.g., a SERP match conditioned on deferral under a 401(k)) is still a nonelective amount for aggregation purposes. The elective portion is Category (A) and the match is Category (B). (Treas. Reg. § 1.409A-1(c)(2)(iii))

Step 5D. Plans Spanning Multiple Categories

• Multi-category plans must be allocated among applicable categories. If a single plan provides benefits that fall into more than one of the nine categories, the plan must be allocated among the applicable categories. (Treas. Reg. § 1.409A-1(c)(2)(iv))
  • The allocation is based on the character of each benefit provided under the plan. If a plan provides both account balance benefits and nonaccount balance benefits, the account balance portion is allocated to Category (A) or (B) and the nonaccount balance portion is allocated to Category (C).
  • The regulations do not prescribe a specific allocation methodology. A reasonable allocation based on the terms of the plan and the nature of the benefits provided is sufficient.
• Plan termination affects all plans in the same category. If a service recipient terminates a plan, the service recipient must terminate all plans in the same category sponsored by the service recipient with respect to which the service recipient has authority to terminate the plan. (Treas. Reg. § 1.409A-1(c)(2)(iv))
  • A partial termination of only some plans within a category is not permitted. If an employer maintains three elective deferral account balance plans and seeks to terminate one, it must terminate all three.
  • The termination rule prevents employers from selectively terminating plans to accelerate payments from favorable arrangements while preserving less favorable ones.

Step 6. Consequences of Plan Aggregation - The Cross-Plan Taint

"If a plan fails to meet the requirements of § 409A(a), all amounts deferred under the plan are includible in the gross income of the participant." § 409A(a)(1)(A)(i).

• An operational failure in one aggregated plan taints all plans in the same category. Because Treas. Reg. § 1.409A-1(c)(2)(i) treats all plans in the same category as a single plan, an operational failure in any one arrangement constitutes a failure of the entire aggregated plan. (Treas. Reg. § 1.409A-1(c)(2)(i))
  • The failure of one plan document to comply with § 409A's distribution rules is a failure of the entire aggregated plan for that service provider in that category.
  • The cross-plan taint effect is one of the most dangerous features of § 409A. A small, obscure arrangement with a technical defect can trigger penalties on all deferred amounts in the same category.
• Income inclusion applies to ALL deferred amounts under all aggregated plans. When an operational failure occurs in one plan within a category, all deferred amounts under all plans in that aggregated category become includible in the participant's gross income for the taxable year in which the failure occurs. (§ 409A(a)(1)(A)(i)) (Treas. Reg. § 1.409A-1(c)(2)(i))
  • The includible amount is not limited to the amounts under the plan with the defect. It extends to all amounts deferred under all plans in the same category.
  • The income inclusion includes amounts that remain subject to a substantial risk of forfeiture ONLY to the extent the amounts are not subject to SRF. If an amount in an aggregated plan is still subject to a substantial risk of forfeiture at the time of the failure, that amount is not includible until the SRF lapses. (IRC § 409A(a)(1)(A)(i))
• The 20% additional tax and premium interest apply to the full includible amount. The § 409A(a)(1)(B) 20% tax and the § 409A(a)(1)(B)(ii) premium interest apply to the total amount includible under the aggregated plan, not merely the amounts under the defective arrangement. (§ 409A(a)(1)(B)-(C))
  • The amplification effect can be staggering. A minor operational error in one plan can trigger penalties on millions of dollars of deferred compensation across multiple arrangements.
  • The premium interest is computed separately for each deferred amount based on its own deferral date or vesting date. Amounts deferred in earlier years accrue more interest than amounts deferred in later years. The total premium interest tax is the sum of the interest on each includible amount. (IRC § 409A(a)(1)(B)(ii))
• The participant-specific limitation restricts the taint to affected participants. The income inclusion and penalties apply only with respect to the participant for whom the failure relates. A failure affecting one participant in an aggregated plan does not trigger inclusion for other participants. (§ 409A(a)(1)(A)) (Treas. Reg. § 1.409A-4(a)(1))
  • If an employer maintains a single elective deferral plan covering 50 executives, and an operational failure occurs with respect to one executive's account, that executive is subject to income inclusion on all deferred amounts in the category. The other 49 executives are not affected unless the same or a different failure relates to them.
  • A plan-level defect that affects all participants (such as an impermissible acceleration provision in a plan document) triggers inclusion for every participant in the plan, because the failure "relates to" each participant whose plan includes the defective provision. (Treas. Reg. § 1.409A-4(a)(1))
• EXAMPLE. The cross-plan taint in operation. Employee E participates in three plans of Employer X, all elective deferral account balance plans (Category (A)).
  • Plan 1 is a supplemental executive retirement plan with a $500,000 deferred balance. Plan 2 is a deferred bonus plan with a $1,000,000 deferred balance. Plan 3 is a salary deferral plan with a $200,000 deferred balance. Plan 1 contains a provision allowing the employer to accelerate payments upon a liquidity event. This provision violates § 409A(a)(3)'s prohibition on acceleration. Because all three plans are in Category (A) and are aggregated under § 1.409A-1(c)(2)(i)(A), the operational failure in Plan 1 constitutes a failure of the entire aggregated plan. Employee E must include $1,700,000 in gross income, pay a 20% additional tax of $340,000, and pay premium interest calculated from the dates each amount was first deferred or first no longer subject to a substantial risk of forfeiture. The $200,000 in Plan 3 and the $1,000,000 in Plan 2 are penalized even though those plans contain no defective provisions.
  • Amplification effect. The penalty on the $1,700,000 includible amount (regular income tax + 20% additional tax of $340,000 + premium interest) can exceed $700,000 in total, triggered solely by a single defective acceleration clause in Plan 1. This illustrates why § 409A compliance requires review of every arrangement in every category, not merely the largest plans.
• TRAP. Cross-plan taint operates even with zero-balance defective plans. The cross-plan taint operates even where the defective plan has a zero or minimal balance.
  • If a participant has one Category (A) plan with $10,000 in it and another Category (A) plan with $5,000,000 in it, an operational failure in the $10,000 plan triggers penalties on the full $5,010,000. Practitioners should review ALL arrangements in a category, not merely the largest ones. (Treas. Reg. § 1.409A-1(c)(2)(i))
  • A plan with a zero balance but an impermissible acceleration provision still constitutes a § 409A failure for that participant in that category, because the failure relates to the participant even if no deferred amount is currently at risk. The participant's other plans in the same category are fully tainted. (Treas. Reg. § 1.409A-4(a)(1))

Step 7. The Critical Exception - Written Plan Requirement Failures Are Not Aggregated

"The plan aggregation rules of § 1.409A-1(c)(2)(i) do not apply to the written plan requirements of § 1.409A-1(c)(3)." Treas. Reg. § 1.409A-1(c)(3)(viii).

• The written plan requirement exception is a critical plan-saving provision. Treas. Reg. § 1.409A-1(c)(3) requires that a plan be in writing and that the writing satisfy certain documentary requirements. If a plan fails solely because it does not meet the written plan requirements of § 1.409A-1(c)(3), the plan aggregation rules of § 1.409A-1(c)(2)(i) do not apply. (Treas. Reg. § 1.409A-1(c)(3)(viii))
  • This means that a written plan requirement failure in one arrangement does NOT trigger the cross-plan taint on other arrangements in the same category.
  • The exception is narrow and applies ONLY to failures of the written plan requirements in § 1.409A-1(c)(3). It does not apply to operational failures, distribution failures, election failures, or acceleration failures.
• The written plan requirements that trigger the exception. § 1.409A-1(c)(3) requires that the plan be in writing and that the writing include (A) the names or titles of the service providers covered, (B) the amount or formula for determining the amount of deferred compensation, (C) the timing of deferrals and payments, and (D) the form of payment. (Treas. Reg. § 1.409A-1(c)(3)(i)-(vii))
  • A plan that is entirely oral fails the written plan requirement.
  • A plan that is in writing but omits one of the required elements fails the written plan requirement.
  • A plan that is in writing but contains a scrivener's error that does not affect substantive rights may still satisfy the written plan requirement if the error is corrected under the documentary error correction rules.
• The exception applies only where the written plan failure is the SOLE failure. If an arrangement has both a written plan requirement failure and an operational failure, the operational failure triggers the aggregation rules, and the exception in § 1.409A-1(c)(3)(viii) does not apply. (Treas. Reg. § 1.409A-1(c)(3)(viii))
  • TRAP. If an arrangement lacks a written plan AND contains an impermissible acceleration provision, the operational failure taints all aggregated plans in the category. The written plan exception does not shield the other plans. Practitioners must analyze whether ANY operational failure exists before relying on the written plan exception.
  • Operational failure defined. An operational failure includes any failure to comply with § 409A(a)(2) (permissible payment events), § 409A(a)(3) (prohibition on acceleration), or § 409A(a)(4) (election timing). A written plan failure alone (missing or incomplete documentation) does not trigger aggregation. But the coexistence of even one operational failure nullifies the exception entirely. (Treas. Reg. § 1.409A-1(c)(3)(viii))
• EXAMPLE. The written plan exception in operation. Executive F participates in three elective deferral account balance plans (Category (A)) maintained by Employer Y.
  • Arrangement 1 ($300,000 balance) has a fully compliant written plan document satisfying all requirements of § 1.409A-1(c)(3). Arrangement 2 ($200,000 balance) is an oral agreement with no written document, but its substantive terms comply with all § 409A(a) operational requirements (initial elections, permissible payment events, no acceleration, subsequent elections). Arrangement 3 ($100,000 balance) has a compliant written plan document. Because Arrangement 2's only failure is the lack of a written plan, the aggregation rules do not apply to the written plan requirement failure. Arrangement 2 fails § 409A solely under the written plan requirement, and the $200,000 in Arrangement 2 is includible in Executive F's gross income. However, Arrangements 1 and 3 are NOT tainted. The $300,000 in Arrangement 1 and the $100,000 in Arrangement 3 continue to enjoy § 409A tax deferral. Executive F pays income tax, 20% additional tax, and premium interest only on the $200,000 in Arrangement 2.
  • Key takeaway. The written plan exception limits the damage to the amounts under the defective arrangement only. Without the exception, Executive F would have been subject to income inclusion, 20% tax, and premium interest on the full $600,000 across all three arrangements. (Treas. Reg. § 1.409A-1(c)(3)(viii))
• CAUTION. The written plan exception limits aggregation but does not eliminate the failure. The written plan exception in § 1.409A-1(c)(3)(viii) applies ONLY to the aggregation rules. It does NOT eliminate the written plan requirement itself.
  • An arrangement without a written plan still fails § 409A, and the deferred amounts under that arrangement are still subject to income inclusion, the 20% additional tax, and premium interest. The exception merely prevents the written plan failure from spreading to other plans in the same category.
  • Practical implication. An employer with multiple oral arrangements in the same category should document each arrangement separately. The written plan exception protects compliant plans from taint but does not protect the undocumented arrangement from its own failure. (Treas. Reg. § 1.409A-1(c)(3)(viii))
• CAUTION. Operational failures are distinct from written plan failures. Do not confuse the written plan requirement in § 1.409A-1(c)(3) with the documentary requirements for initial elections, permissible payment events, and prohibition on acceleration in § 409A(a)(2)-(4).
  • A plan document that exists but fails to specify permissible payment events commits an operational failure, not merely a written plan failure. The § 1.409A-1(c)(3)(viii) exception does not apply to operational failures. (Treas. Reg. § 1.409A-1(c)(3)(viii))
  • Test. If the plan document were corrected to add the missing permissible payment event, would the plan comply with § 409A(a) operationally? If yes, it is a written plan failure. If no, it is an operational failure.
• Practical application checklist. When analyzing a potential § 409A failure across multiple arrangements, apply the following sequence.
  • First, identify all arrangements in which the service provider participates and categorize each under § 1.409A-1(c)(2)(i).
  • Second, for the arrangement with the apparent failure, determine whether the failure is (a) solely a written plan requirement failure under § 1.409A-1(c)(3), (b) an operational failure under § 409A(a)(2)-(4), or (c) both.
  • Third, if the failure is solely a written plan requirement failure, the aggregation rules do not apply. Only the amounts under the defective arrangement are includible.
  • Fourth, if the failure is an operational failure (either alone or in combination with a written plan failure), the aggregation rules apply. All plans in the same category are tainted, and all deferred amounts in the category are includible.
  • Fifth, if multiple failures exist across multiple arrangements in the same category, each failure is analyzed separately, but the aggregation effect may cumulatively expose all amounts in the category.

Step 8. The Written Plan Requirements

"A plan does not satisfy the requirements of section 409A and this section and §§ 1.409A-2 through 1.409A-3 and §§ 1.409A-5 through 1.409A-6, unless the plan is established and maintained by a service recipient in accordance with the requirements of this section, §§ 1.409A-2 through 1.409A-3 and §§ 1.409A-5 through 1.409A-6." Treas. Reg. § 1.409A-1(c)(3).

"The material terms of the plan include the amount (or the method or formula for determining the amount) of deferred compensation to be provided under the plan and the time and form of payment." Treas. Reg. § 1.409A-1(c)(3)(i).

• Material terms requirement. A plan must set forth in writing the amount (or method/formula for determining the amount) of deferred compensation and the time and form of payment. (Treas. Reg. § 1.409A-1(c)(3)(i))
  • The material terms may be spread across one or more documents. (Treas. Reg. § 1.409A-1(c)(3)(i))
  • The plan is treated as established on the latest of the adoption date, the effective date, and the date material terms are set forth in writing. (Treas. Reg. § 1.409A-1(c)(3)(i))
  • A plan consisting of multiple documents is common. Identify which documents contain the governing plan provisions. Cross-reference Step 5 (plan category determination) to confirm which documents belong to which aggregated plan.
• Deadline for written documentation. The plan must be established in writing by the end of the taxable year of the service provider in which the legally binding right arises. (Treas. Reg. § 1.409A-1(c)(3)(i))
  • For amounts not payable in the year immediately following the year the right arises (the subsequent year), the deadline is extended to the 15th day of the 3rd month of the subsequent year.
  • This deadline parallels the short-term deferral deadline in Step 9. An arrangement that qualifies as a short-term deferral does not need written plan documentation under § 409A.
  • TRAP. Do not confuse the written plan deadline with the short-term deferral deadline. Even if compensation is paid within the short-term deferral window, if the arrangement is subject to § 409A (because payment may occur after the deadline as determined in Step 2), the written plan requirement applies.
• Initial deferral elections. The plan must set forth in writing, on or before the date the election becomes irrevocable, the conditions under which an initial deferral election may be made. (Treas. Reg. § 1.409A-1(c)(3)(ii))
  • Under the general prior-year rule, elections become irrevocable by December 31 of the year preceding the service year. (Treas. Reg. § 1.409A-2(a)(3))
  • For newly eligible participants, the written conditions must be in place within 30 days after the participant first becomes eligible. (Treas. Reg. § 1.409A-2(a)(6))
  • For performance-based compensation, the written conditions must be in place at least 6 months before the end of the performance period. (Treas. Reg. § 1.409A-2(a)(8))
• Subsequent deferral elections. The plan must set forth in writing, on or before the date the election becomes irrevocable, the conditions under which a subsequent deferral election may be made. (Treas. Reg. § 1.409A-1(c)(3)(iii))
  • A subsequent deferral election becomes irrevocable at least 12 months before the first scheduled payment date. (Treas. Reg. § 1.409A-2(b))
  • The written conditions must address the three-prong test. See Step 12 for the full operational requirements.
• Payment accelerations not required in writing. A plan is not required to set forth in writing the conditions under which a payment may be accelerated if the acceleration is permitted under § 1.409A-3(j)(4). (Treas. Reg. § 1.409A-1(c)(3)(iv))
  • Payment accelerations are generally prohibited. The regulatory exceptions in § 1.409A-3(j)(4) include limited cashouts, employment tax payments, domestic relations orders, and plan terminations.
  • CAUTION. Best practice is to include permissible acceleration provisions in the written plan document even though not required. This ensures operational clarity and reduces the risk of inadvertent impermissible accelerations.
• Specified employee six-month delay. The plan must provide in writing that distributions to a specified employee may not be made before the date that is six months after separation from service (or, if earlier, death). (Treas. Reg. § 1.409A-1(c)(3)(v))
  • The six-month delay provision must be set forth in writing on or before the date the service provider first becomes a specified employee. (Treas. Reg. § 1.409A-1(c)(3)(v))
  • A plan does not fail merely because it lacks the six-month delay provision when the service provider is not a specified employee. However, the provision must be in writing before the specified employee effective date for the first list that includes the service provider. See Step 11 for the specified employee definition and identification procedures.
• Plan amendments increasing deferred amounts. An amendment that increases the amount deferred is not established with respect to the additional amount until the amended plan satisfies the written plan requirements of paragraph (c)(3)(i). (Treas. Reg. § 1.409A-1(c)(3)(vi))
  • The deadline for documenting the amendment is the same as for the original plan. The additional amount is subject to the written plan requirement independently of the base amount.
  • TRAP. A plan amendment that increases benefits retroactively may trigger a written plan failure for the incremental amount even if the original plan was fully compliant.
• Transition rule for pre-2008 plans. A legally enforceable unwritten plan adopted and effective before December 31, 2007 is treated as established if the material terms were set forth in writing on or before December 31, 2007. (Treas. Reg. § 1.409A-1(c)(3)(vii))
  • This transition rule is largely historical. Any plan still relying on this relief should have been documented by December 31, 2007. Verify the plan document date if a client claims this transition relief.
  • A plan that was both legally enforceable and in writing by December 31, 2007 satisfies the written plan requirement even if the writing was incomplete or did not comply with the full § 1.409A-1(c)(3) requirements so long as the material terms (amount, timing, form of payment) were ascertainable from the written documents. (Treas. Reg. § 1.409A-1(c)(3)(vii))
• Written plan failures are NOT aggregated. The plan aggregation rules of § 1.409A-1(c)(2)(i) do not apply to the written plan requirements. (Treas. Reg. § 1.409A-1(c)(3)(viii))
  • An arrangement that fails § 409A solely due to a written plan documentation failure is not aggregated with other arrangements that meet the written plan requirements.
  • CAUTION. This safe harbor applies only if the written plan requirement is the sole failure. If the arrangement also has operational failures or substantive noncompliance (impermissible payment events, invalid elections), the aggregation rules apply and all plans in the same category (as determined in Step 5) are tainted.
• Consequence of written plan failure. If a plan fails the written plan requirement, all compensation deferred under that specific arrangement for the taxable year and all preceding taxable years becomes includible in gross income to the extent not subject to a substantial risk of forfeiture and not previously included. (IRC § 409A(a)(1)(A)(i))
  • The service provider is also subject to the 20% additional tax and premium interest tax. See Step 6 for the full penalty analysis.
  • Because the aggregation rules do not apply, other properly documented arrangements in the same plan category are not affected by the written plan failure of one arrangement. (Treas. Reg. § 1.409A-1(c)(3)(viii))
• TRAP. "As soon as reasonably practicable" language and its limits. "As soon as reasonably practicable" language following a permissible payment event does not by itself cause a written plan failure. (Notice 2010-6, § IV)
  • The IRS has recognized that this language is commonly used and will not treat it as a failure to specify the time of payment if the payment is in fact made within a reasonable administrative period following the event. The reasonable administrative period is generally presumed not to exceed 90 days following the payment event.
  • CAUTION. The "as soon as reasonably practicable" safe harbor applies only when the language follows a permissible payment event. If the plan uses this language as the standalone payment timing without reference to a § 409A-permissible event, the plan may fail the written plan requirement.
  • EXAMPLE. A plan provides for payment "as soon as reasonably practicable following separation from service." The separation occurs on June 1. Payment is made on August 1 (61 days later). The plan satisfies the written plan requirement because the timing language follows a permissible payment event and payment occurred within a reasonable administrative period. (Notice 2010-6, § IV)

Step 9. Exemptions from § 409A Coverage

"Compensation for services performed during a taxable year is not treated as deferred compensation for purposes of section 409A and this section and §§ 1.409A-2 through 1.409A-6 if the compensation is paid not later than the applicable 2 1/2 month period." Treas. Reg. § 1.409A-1(b)(4).

• Short-term deferral. A payment is not treated as a deferral of compensation if the service provider actually or constructively receives the payment on or before the later of (i) the 15th day of the 3rd month after the end of the service provider's taxable year in which the right is no longer subject to a substantial risk of forfeiture, or (ii) the 15th day of the 3rd month after the end of the service recipient's taxable year in which the right is no longer subject to a substantial risk of forfeiture. (Treas. Reg. § 1.409A-1(b)(4))
  • For a calendar-year individual employed by a calendar-year employer, the deadline is March 15 of the year following the year in which the right is no longer subject to SRF.
  • The "may be" standard. If payment under the plan MAY be made after the short-term deferral deadline, the arrangement IS subject to § 409A even if the triggering event actually occurs within the short-term period. (Treas. Reg. § 1.409A-1(b)(4)(i)(A))
  • EXAMPLE. An executive is entitled to a bonus payable upon separation from service. The separation occurs on January 15 and the bonus is paid on February 1, well within the short-term deferral period. Because the plan provides for payment upon an event (separation) that MAY occur after the short-term deadline, § 409A applies in full.
  • Installment payments are treated as a single payment. If any installment would be paid outside the short-term period, none of the payments qualify. (Treas. Reg. § 1.409A-1(b)(4)(ii)) A plan may elect in writing to treat installments as separate payments.
  • CAUTION. The exemption analysis must be performed at the time the legally binding right arises (as determined in Step 2). An arrangement that starts as a short-term deferral can later become subject to § 409A if its terms change to permit later payment.
• Stock rights exemption. A stock option or stock appreciation right does not provide for a deferral of compensation if all conditions in Treas. Reg. § 1.409A-1(b)(5)(i)(A) are met.
  • The option/SAR must be over service recipient stock. (Treas. Reg. § 1.409A-1(b)(5)(i)(A)(1))
  • The exercise price may never be less than the FMV of the underlying stock on the date of grant. (Treas. Reg. § 1.409A-1(b)(5)(i)(A)(2))
  • The transfer or exercise is subject to taxation under § 83 and § 1.83-7. (Treas. Reg. § 1.409A-1(b)(5)(i)(A)(3))
  • The stock right does not include any feature for the deferral of compensation beyond the deferral of recognition of income until the later of exercise/disposition or the time the stock first becomes substantially vested. (Treas. Reg. § 1.409A-1(b)(5)(i)(A)(4))
  • Incentive stock options under § 422 and ESPP options under § 423 are fully exempt from § 409A regardless of whether they would satisfy the NQSO exemption conditions. (Treas. Reg. § 1.409A-1(b)(5)(ii))
  • See Step 10 for the detailed equity compensation analysis.
• Restricted property. There is no deferral of compensation merely because the value of property is not includible in income due to the property being substantially nonvested under § 83. (Treas. Reg. § 1.409A-1(b)(6))
  • A promise to transfer substantially nonvested property in a future taxable year is NOT deferred compensation unless offered in conjunction with another legally binding right that constitutes a deferral of compensation. (Treas. Reg. § 1.409A-1(b)(6)(ii))
  • A valid § 83(b) election does not cause an arrangement to become subject to § 409A. The restricted property exemption continues to apply.
  • TRAP. A promise to transfer fully vested property in a future year IS deferred compensation subject to § 409A. Distinguish between restricted stock (property transferred, subject to § 83) and a promise to transfer stock in the future (unfunded promise, subject to § 409A).
• Reimbursement arrangements. Post-separation reimbursements for business expenses, outplacement, moving expenses, and medical expenses during the COBRA continuation period are excluded from the definition of deferred compensation. (Treas. Reg. § 1.409A-1(b)(9)(v))
  • Expenses must be incurred by the end of the 2nd taxable year following the taxable year of separation. (Treas. Reg. § 1.409A-1(b)(9)(v)(A))
  • Reimbursement for expenses incurred by the service provider must be paid no later than the end of the 3rd taxable year following the taxable year of separation. (Treas. Reg. § 1.409A-1(b)(9)(v)(B))
  • In-kind benefits must be provided by the end of the 2nd taxable year following separation. (Treas. Reg. § 1.409A-1(b)(9)(v)(C))
  • CAUTION. This exemption applies only to reimbursement arrangements that are otherwise excludible from gross income. Taxable reimbursements are not covered by this exemption and may be subject to § 409A.
• Separation pay plan exemption. A separation pay plan providing pay solely upon involuntary separation from service or pursuant to a window program does not provide for a deferral of compensation to the extent the separation pay meets the dollar and time limits. (Treas. Reg. § 1.409A-1(b)(9)(iii))
  • Dollar limit. The separation pay must not exceed two times the lesser of (i) the service provider's annualized compensation based on the prior taxable year's rate of pay, or (ii) the § 401(a)(17) limit for the calendar year of separation ($700,000 for 2025, producing a maximum exempt amount of $1,400,000). (Treas. Reg. § 1.409A-1(b)(9)(iii)(A))
  • Time limit. All separation pay must be paid no later than the last day of the 2nd taxable year following the taxable year of separation. (Treas. Reg. § 1.409A-1(b)(9)(iii)(B))
  • Window programs. A program offering benefits to a group or subgroup of employees for a limited period not exceeding 12 months in connection with a separation from service. (Treas. Reg. § 1.409A-1(b)(9)(vi)) Window program payments are subject to the same dollar and time limits as involuntary separation pay.
  • Only the excess over the applicable limit is subject to § 409A. The portion up to the limit is not subject to § 409A, including the six-month specified employee delay requirement, provided it is paid by the applicable deadline. (Treas. Reg. § 1.409A-1(b)(9)(iii)(C))
  • See Step 11 for the full severance analysis, including the good reason safe harbor and stacking rules.
• Legal settlements. An agreement providing for amounts paid as settlements or awards resolving bona fide legal claims based on wrongful termination, employment discrimination, the Fair Labor Standards Act, or workers' compensation statutes does not provide for a deferral of compensation. (Treas. Reg. § 1.409A-1(b)(11))
  • The exclusion covers reimbursements or payments of reasonable attorneys' fees and other reasonable expenses incurred to enforce a bona fide legal claim against the service recipient. (Treas. Reg. § 1.409A-1(b)(11)(ii))
  • TRAP. This exemption applies only to amounts arising from an actual bona fide claim. It does not apply to amounts that would have been paid regardless of the claim, or to amounts paid solely upon execution of a waiver of claims without an underlying bona fide dispute.
  • A change to the timing of payment of preexisting deferred compensation as part of a settlement is still subject to the § 409A acceleration and subsequent deferral election rules. The settlement exclusion covers only the damages arising from the legal claim itself.
• Educational benefits. Rights to educational benefits consisting solely of educational assistance as defined for purposes of § 127(c), provided solely for the education of the service provider, are excepted from the definition of deferred compensation. (Treas. Reg. § 1.409A-1(b)(12))
  • § 127(c) defines educational assistance as the payment of expenses for tuition, fees, books, supplies, and equipment incurred in connection with the education of the employee. The § 127 exclusion is limited to $5,250 per calendar year. Educational benefits exceeding this amount may be taxable compensation but are still excluded from § 409A if they meet the § 127(c) definition. (Treas. Reg. § 1.409A-1(b)(12))
  • The exclusion applies only to educational benefits for the service provider, not for family members. A promise to pay tuition for a service provider's child is NOT within this exclusion and may constitute deferred compensation if payment is deferred to a later taxable year. (Treas. Reg. § 1.409A-1(b)(12))
• Foreign plan exclusions. The term NQDC plan does not include broad-based foreign retirement plans maintained for nonresident aliens and certain resident aliens. (Treas. Reg. § 1.409A-1(a)(3)(ii)) Amounts deferred under foreign social security systems covered by totalization agreements are also excluded. (Treas. Reg. § 1.409A-1(a)(3)(iv))
  • A "broad-based foreign retirement plan" must be mandated or sponsored by a foreign government, substantially similar to U.S. Social Security, and non-discriminatory in coverage. Plans that supplement the foreign social security benefit and are employer-sponsored may still be subject to § 409A if they provide deferred compensation beyond the mandated foreign benefit. (Treas. Reg. § 1.409A-1(a)(3)(ii))
  • A totalization agreement is a bilateral agreement between the United States and a foreign government that coordinates social security coverage for workers who divide their careers between the two countries. Amounts deferred under the foreign social security system that is party to the totalization agreement are excluded from § 409A. Employer-sponsored supplemental plans are not covered by this exclusion. (Treas. Reg. § 1.409A-1(a)(3)(iv))
• Welfare benefit exclusions. Bona fide vacation leave, sick leave, compensatory time, disability pay, and death benefits are excluded from the definition of NQDC plan. (Treas. Reg. § 1.409A-1(a)(5)) Health savings accounts, Archer medical savings accounts, and medical reimbursement arrangements satisfying § 105 and § 106 are also excluded.
  • Each welfare benefit exclusion requires a BONA FIDE plan. An arrangement that pays a formulaic lump sum at termination unrelated to actual accrued leave balances is not a bona fide vacation or sick leave plan. The bona fide standard requires that the benefit be calculated from accrued, objectively measurable leave balances. (Treas. Reg. § 1.409A-1(a)(4))
  • Medical reimbursement arrangements must satisfy the requirements of Notice 2002-45 and Notice 2002-69 to qualify for the welfare benefit exclusion. An arrangement that reimburses medical expenses without limit and without reference to an insurance framework may not qualify as a bona fide medical reimbursement plan and may be recharacterized as deferred compensation. (Treas. Reg. § 1.409A-1(a)(4)) (Notice 2002-45)
• Independent contractor exception. § 409A generally does not apply to amounts deferred under an arrangement with an unrelated service recipient if the service provider is actively engaged in providing significant services to two or more unrelated service recipients. (Treas. Reg. § 1.409A-1(f)(2))
  • The 70% revenue safe harbor provides that a service provider is treated as providing significant services to two or more unrelated service recipients if at least 70% of the service provider's gross revenue during the current or preceding taxable year is from providing services to three or fewer unrelated service recipients. (Treas. Reg. § 1.409A-1(f)(2)(iii))
  • Even if the 70% safe harbor is not met, a service provider may still qualify for the exception if the facts and circumstances demonstrate active engagement in providing significant services to multiple unrelated recipients. Factors include the time devoted, the revenue generated, and the contractual relationships with each recipient. (Treas. Reg. § 1.409A-1(f)(2))
• CAUTION. Exemption depends on both plan terms and actual payment timing. If payment under an exempt arrangement is actually delayed beyond the exemption period, the arrangement may retroactively become subject to § 409A.
  • The exemption depends on both the plan terms and the actual timing of payment. Verify that actual payment occurred within the exemption window before concluding that § 409A does not apply. An arrangement that qualifies for the short-term deferral exemption on its face loses the exemption if payment is not actually made within the 2.5-month window.
  • CAUTION. Do not assume that an exemption applies retroactively once the payment deadline has passed. If payment was not made within the exemption period, the arrangement is subject to § 409A from the date the legally binding right arose, and the full penalty regime applies unless the arrangement complies with all § 409A(a) operational requirements. (Treas. Reg. § 1.409A-1(b)(4))

Step 10. Equity Compensation and § 409A

"[A]n incentive stock option described in section 422, or an option granted under an employee stock purchase plan described in section 423, does not provide for a deferral of compensation." Treas. Reg. § 1.409A-1(b)(5)(ii).

• NQSO exemption conditions. A nonqualified stock option is not deferred compensation if all four conditions are satisfied. (Treas. Reg. § 1.409A-1(b)(5)(i)(A))
  • The option is over service recipient stock.
  • The exercise price may never be less than the FMV of the underlying stock on the grant date.
  • Receipt, transfer, and exercise are subject to § 83 and § 1.83-7.
  • There is no additional deferral feature beyond deferral until the later of exercise/disposition or when the stock first becomes substantially vested.
  • If any condition is not met, the entire option is treated as deferred compensation subject to § 409A. The exemption is all-or-nothing.
• Service recipient stock. For stock rights purposes, "service recipient stock" includes stock of the corporation for which the service provider performs services and stock of certain affiliated entities. (Treas. Reg. § 1.409A-1(b)(5)(iii))
  • The parent-subsidiary chain requires a 50% ownership interest (lower than the 80% threshold used for other compensation purposes under § 414(b) and (c)). (Treas. Reg. § 1.409A-1(b)(5)(iii)(B))
  • Where the use of such stock is based on legitimate business criteria, only a 20% interest is required. (Treas. Reg. § 1.409A-1(b)(5)(iii)(B))
  • TRAP. The lower ownership thresholds for stock rights (50% or 20%) differ from the thresholds used for plan aggregation and other § 409A purposes (80%). Do not conflate the two analyses.
• FMV determination for public companies. For stock readily tradable on an established securities market, FMV may be determined using any reasonable method based on actual transactions. (Treas. Reg. § 1.409A-1(b)(5)(iv)(A))
  • Acceptable methods include the last sale before or first sale after the grant, the closing price on the trading day before or of the grant, or the arithmetic mean of the high and low prices on such trading day.
  • An average over a specified period within 30 days before and after the grant date is permitted if the terms are irrevocably established before the beginning of the averaging period.
• FMV determination for private companies. For stock not readily tradable, FMV must be determined by the reasonable application of a reasonable valuation method. (Treas. Reg. § 1.409A-1(b)(5)(iv)(B))
  • Safe harbor (1). Independent appraisal. A valuation determined by an independent appraisal meeting § 401(a)(28)(C) requirements, dated no more than 12 months before the grant. (Treas. Reg. § 1.409A-1(b)(5)(iv)(B)(1))
  • Safe harbor (2). Formula. A valuation based on a formula used consistently for all noncompensatory purposes. (Treas. Reg. § 1.409A-1(b)(5)(iv)(B)(2))
  • Safe harbor (3). Illiquid start-up corporation. A valuation made reasonably and in good faith of illiquid stock of a start-up corporation (no trade or business conducted for 10+ years, no publicly traded stock, not subject to put/call rights), performed by a person with significant knowledge and experience. (Treas. Reg. § 1.409A-1(b)(5)(iv)(B)(3))
  • Consistent use of any safe harbor method creates a presumption of reasonableness rebuttable only upon showing the method or application was "grossly unreasonable." (Treas. Reg. § 1.409A-1(b)(5)(iv)(B))
• Discounted options. An option with an exercise price below FMV on the grant date IS deferred compensation subject to § 409A. (Treas. Reg. § 1.409A-1(b)(5)(i)(C))
  • The entire option is subject to § 409A, not merely the discount amount.
  • TRAP. A discounted option cannot be "cured" by amendment to increase the exercise price to FMV. Such an amendment is treated as a substitution and does not retroactively exempt the option from § 409A. However, transition relief in Notice 2006-79 permitted substitution of non-discounted options for discounted ones through December 31, 2008.
• Modifications. A modification of a stock right is treated as the grant of a new stock right. (Treas. Reg. § 1.409A-1(b)(5)(v))
  • An extension of the exercise period (providing additional time beyond the original expiration date) causes the stock right to be treated as having had an additional deferral feature from the original date of grant. This results in retroactive § 409A application to the entire arrangement. (Treas. Reg. § 1.409A-1(b)(5)(v)(C))
  • Extension safe harbor. Extending the exercise period to a date no later than the earlier of (i) the latest date the stock right could have expired under its original terms, or (ii) the 10th anniversary of the original grant date, is not treated as an extension. (Treas. Reg. § 1.409A-1(b)(5)(v)(C))
  • CAUTION. Any modification that could reduce the exercise price below the original FMV on grant date (such as a repricing) is treated as a new grant and the original grant is treated as having contained a deferral feature from its inception.
• Dividend equivalents. A dividend equivalent right that is directly or indirectly contingent upon the exercise of a stock right constitutes an offset to the exercise price (for NQSOs) or an increase in the amount payable (for SARs). (Treas. Reg. § 1.409A-1(b)(5)(i)(D))
  • Such contingent dividend equivalents cause the related stock right to fail the § 409A exemption.
  • A dividend equivalent right that is not contingent upon exercise (paid separately on the underlying shares regardless of exercise) does not cause the related stock right to fail the exemption. (Treas. Reg. § 1.409A-1(b)(5)(i)(D)(2))
  • The non-contingent dividend equivalent right may itself be deferred compensation subject to § 409A, but it will not affect the exemption status of the related stock right.
• RSUs. Restricted stock units are unfunded promises to transfer stock (or cash equal to stock value) in the future. They are generally deferred compensation subject to § 409A. (Treas. Reg. § 1.409A-1(b)(6) and related guidance)
  • RSUs are NOT property under § 83 because no actual transfer occurs at grant. A § 83(b) election is unavailable for RSUs.
  • Stock-settled RSUs are generally subject to § 409A unless they qualify for the short-term deferral exemption (e.g., vesting and settlement both occur within the 2.5-month period). (Treas. Reg. § 1.409A-1(b)(4))
  • Cash-settled RSUs are always subject to § 409A (no § 83 property transfer occurs at any point).
  • To comply with § 409A, an RSU must specify the time of payment (e.g., on the vesting date or within a specified period after vesting) and may not permit acceleration except under the regulatory safe harbors in § 1.409A-3(j)(4).
  • TRAP. Some RSU designs provide for payment "as soon as administratively practicable" after vesting. If this period extends beyond the short-term deferral window, the RSU is subject to § 409A and must comply with all operational requirements in Step 12.
• ISOs and ESPPs. Statutorily exempt from § 409A. (Treas. Reg. § 1.409A-1(b)(5)(ii))
  • An ISO that fails ISO requirements (e.g., disqualifying disposition, failure to meet holding periods) may become subject to § 409A if it also fails the NQSO exemption conditions. (Treas. Reg. § 1.409A-1(b)(5)(ii))
  • A modification of an ISO that is treated as the grant of a new option that is not a statutory option triggers § 409A analysis. The modified option is tested for the NQSO exemption as of the modification date. (Treas. Reg. § 1.424-1(e))
  • CAUTION. An ESPP option with a discounted purchase price under § 423(b)(6) is fully exempt from § 409A. The exemption applies regardless of the discount. Do not confuse ESPP discounting with NQSO discounting.
• Phantom stock and deferred equity. Phantom stock arrangements (promises to pay cash equal to the value of stock) are deferred compensation subject to § 409A. They are not stock rights because no option or SAR is granted.
  • A phantom stock plan must comply with all § 409A requirements including permissible payment events, written plan requirements, and election timing rules. See Steps 8 and 12.
  • Phantom stock units are typically valued by reference to the employer's actual stock price. The plan must specify the valuation method, the time of valuation (e.g., the payment date or an averaging period), and the permissible payment events. A phantom stock plan that permits payment upon events other than the six statutory permissible events commits an operational failure subjecting all aggregated Category (A) or (C) plans to the penalty regime. (Treas. Reg. § 1.409A-1(c)(2)(i))

Step 11. Severance Arrangements and Separation Pay

"A separation pay plan providing for separation pay solely upon an involuntary separation from service or pursuant to a window program does not provide for a deferral of compensation to the extent that the separation pay meets the requirements of this paragraph (b)(9)(iii)." Treas. Reg. § 1.409A-1(b)(9)(iii).

• Separation pay plan definition. A separation pay plan is a plan providing separation pay solely upon involuntary separation from service or pursuant to a window program. (Treas. Reg. § 1.409A-1(b)(9))
  • The term "plan" for this purpose follows the aggregation rules in Step 5. An executive's employment agreement, change-in-control agreement, SERP, and equity award may each contain separation pay provisions. Under the category D aggregation rules (involuntary separation pay plans), all separation pay plans payable upon involuntary separation are treated as a single plan. A § 409A violation in one document affects all separation pay under all aggregated documents.
  • A plan that provides separation pay upon both involuntary separation AND voluntary separation (or other non-involuntary events) is NOT a separation pay plan for the portion that pays upon non-involuntary events. The portion payable upon involuntary separation may qualify for the exemption, but the other portion is subject to § 409A. (Treas. Reg. § 1.409A-1(b)(9)(iii))
• Involuntary separation. Employer-initiated termination. The determination is based on all facts and circumstances. (Treas. Reg. § 1.409A-1(n)(1))
  • An involuntary separation does NOT include voluntary termination, retirement, or voluntary resignation.
  • A separation may be treated as involuntary if it results from the employer's failure to renew a contract at expiration, provided the service provider was willing and able to execute a new contract on substantially similar terms. (Treas. Reg. § 1.409A-1(n)(1))
  • Any characterization of the separation as voluntary or involuntary in documentation is presumed correct but may be rebutted where facts and circumstances indicate otherwise. (Treas. Reg. § 1.409A-1(n)(1))
• Good reason safe harbor. If a plan defines good reason as an involuntary separation, the safe harbor requires all of the following. (Treas. Reg. § 1.409A-1(n)(2))
  • One of six enumerated conditions must occur. (Treas. Reg. § 1.409A-1(n)(2)(i)) The conditions are (A) material diminution in base compensation, (B) material diminution in authority/duties/responsibilities, (C) material diminution in authority/duties/responsibilities of the supervisor, (D) material diminution in the budget the employee retains authority over, (E) material change in geographic location, or (F) any other action or inaction that constitutes a material breach by the employer.
  • The employee must give notice to the employer within 90 days after the condition first occurs. (Treas. Reg. § 1.409A-1(n)(2)(ii))
  • The employer must have at least 30 days to cure. (Treas. Reg. § 1.409A-1(n)(2)(iii))
  • The employee must terminate within a specified period not exceeding 2 years after the condition first occurs. (Treas. Reg. § 1.409A-1(n)(2)(iv))
  • Plans may use a narrower definition of good reason without penalty. A plan that defines good reason more narrowly than the safe harbor still qualifies for the involuntary separation exemption provided the definition is objectively determinable.
  • CAUTION. If a plan defines good reason more broadly than the safe harbor (e.g., permitting termination for "any good reason" without the enumerated conditions), the plan may fail to qualify for the involuntary separation exemption.
• Window programs. A program established to provide separation pay for a limited period not exceeding 12 months to service providers who separate during that period. (Treas. Reg. § 1.409A-1(b)(9)(vi))
  • A program will not qualify as a window program if the service recipient establishes a pattern of repeatedly providing similar separation pay in similar situations for substantially consecutive limited periods. (Treas. Reg. § 1.409A-1(b)(9)(vi))
  • Relevant factors include whether the benefits are on account of a specific business event, the degree to which the separation pay relates to the event, and whether the event is temporary/discrete or permanent.
• Dollar limit. The separation pay must not exceed two times the lesser of (i) annualized compensation based on the prior taxable year's rate of pay (adjusted for expected continuing increases), or (ii) the § 401(a)(17) limit for the year of separation ($350,000 for 2025, yielding a $700,000 maximum exemption). (Treas. Reg. § 1.409A-1(b)(9)(iii)(A))
  • For a service provider with no compensation in the preceding taxable year, use the annualized compensation for the taxable year of separation.
  • The dollar limit is applied to the TOTAL separation pay under all aggregated separation pay plans. If an executive has a $400,000 exempt severance in the employment agreement and a $400,000 exempt severance in a change-in-control agreement, the aggregate $800,000 exceeds the $700,000 cap and $100,000 is subject to § 409A. (Treas. Reg. § 1.409A-1(c)(2)(i)(D))
• Time limit. All separation pay must be paid no later than the last day of the 2nd taxable year following the taxable year of separation. (Treas. Reg. § 1.409A-1(b)(9)(iii)(B))
  • EXAMPLE. An employee separates on October 15, 2025. All exempt separation pay must be paid by December 31, 2027. If the plan provides for payment in installments extending into 2028, the installments paid in 2028 are subject to § 409A.
  • Installment payments. If separation pay is paid in installments, each installment must be paid by the end of the 2nd taxable year following separation. An installment schedule that extends payment beyond this deadline causes the entire amount exceeding the deadline to be subject to § 409A. The plan may elect in writing to treat installments as separate payments, in which case each installment is tested separately. (Treas. Reg. § 1.409A-1(b)(9)(iii)(B))
• Stacking exemptions. The short-term deferral and separation pay exemptions may be combined ("stacked"). (Treas. Reg. § 1.409A-1(b)(9), introductory language)
  • Amounts paid within the short-term deferral period (by the later of the 15th day of the 3rd month after the end of the service provider's or service recipient's taxable year) are exempt as short-term deferrals regardless of the separation pay cap.
  • EXAMPLE. A CEO with $500,000 base salary receives severance of 3x base ($1.5 million) payable in monthly installments over 12 months following October 1, 2025 separation. The installments paid on or before March 15, 2026 qualify for the short-term deferral exemption (no dollar limit). The remaining installments up to the $700,000 separation pay cap qualify under the separation pay exemption. Only amounts above the cap are subject to § 409A.
• Specified employee six-month delay. Specified employees of publicly traded companies must delay separation-from-service payments for 6 months (or until death, if earlier). (IRC § 409A(a)(2)(B)(i)) (Treas. Reg. § 1.409A-3(i)(2))
  • This applies to all payments triggered by separation from service, including severance payments that exceed the separation pay exemption limit.
  • The six-month delay does NOT apply to amounts that qualify for the separation pay exemption. (Treas. Reg. § 1.409A-1(b)(9)(iii)(C))
  • The six-month delay does NOT apply to payments triggered by events other than separation (change in control, disability, death, fixed date, unforeseeable emergency).
• Specified employee definition. A specified employee is a key employee under § 416(i)(1)(A) of a publicly traded corporation. (Treas. Reg. § 1.409A-1(i)(1))
  • The three categories are (i) officers with annual compensation above the indexed threshold ($230,000 for 2024), limited to the top 50 officers, (ii) 5% owners, and (iii) 1% owners with compensation over $150,000. (IRC § 416(i)(1)(A))
  • The default identification date is December 31. The default effective date is April 1 of the following year. (Treas. Reg. § 1.409A-1(i)(3) and (4))
  • A service recipient may designate an alternative identification date, provided it is used consistently for all NQDC plans and any change may not be effective for at least 12 months. (Treas. Reg. § 1.409A-1(i)(6) and (8))
  • CAUTION. A private company going public must implement specified employee procedures before the first public trading date. If the company has deferred compensation plans that provide for payment upon separation, the six-month delay provision must be in writing before any employee first becomes a specified employee. (Treas. Reg. § 1.409A-1(c)(3)(v))
• Anti-substitution rule. While stacking is permitted, substituting amounts that are not deferred compensation for amounts that are deferred compensation is prohibited. (Treas. Reg. § 1.409A-1(b)(9) and related guidance)
  • EXAMPLE. An arrangement may provide that a discretionary amount is payable promptly upon involuntary termination (short-term deferral), and that fixed payments will be made over three years (§ 409A-compliant deferred compensation). However, if the arrangement provides that the deferred compensation amount is a gross amount less the discretionary short-term amount, that is an impermissible substitution. The exercise of discretion to increase the short-term amount would effectively reduce the deferred compensation amount in violation of § 409A.
  • Test for substitution. The anti-substitution rule is violated when the amount of deferred compensation is calculated by reference to or is reduced by the amount of an exempt payment. If the exempt payment and the deferred compensation are independent amounts (each determined by its own formula without cross-reference), stacking is permissible. If one amount is a residual of the other, the arrangement violates the anti-substitution rule. (Treas. Reg. § 1.409A-1(b)(9))

Step 12. Operational Requirements - Elections, Distributions, and Acceleration

"A plan that is, or constitutes part of, a nonqualified deferred compensation plan meets the requirements of section 409A(a)(4)(B) if under the terms of the plan, compensation for services performed during a service provider's taxable year may be deferred at the service provider's election only if the election to defer such compensation is made not later than the close of the service provider's taxable year next preceding the service year." Treas. Reg. § 1.409A-2(a)(3).

• Initial deferral elections (the prior-year rule). A plan may permit a service provider to defer compensation for a taxable year only if the election is made not later than the close of the taxable year next preceding the service year. (Treas. Reg. § 1.409A-2(a)(3))
  • The election must be irrevocable by the deadline.
  • First year of eligibility exception. A newly eligible participant may make an initial deferral election within 30 days after first becoming eligible. The election applies only to compensation for services performed after the election. (Treas. Reg. § 1.409A-2(a)(6))
  • Performance-based compensation exception. An initial deferral election may be made with respect to performance-based compensation on or before the date that is 6 months before the end of the performance period, provided the service provider performs services continuously from the later of the beginning of the performance period or the date the performance criteria are established through the date of the election. (Treas. Reg. § 1.409A-2(a)(8))
  • "Performance-based compensation" means compensation the amount of which, or the entitlement to which, is contingent on the satisfaction of pre-established organizational or individual performance criteria. (Treas. Reg. § 1.409A-1(e))
  • Forfeitable rights exception. An initial deferral election may be made within 30 days after obtaining a legally binding right to compensation that is subject to a forfeiture condition requiring at least 12 months of future service. The election applies only to compensation that would otherwise be paid after the election. (Treas. Reg. § 1.409A-2(a)(4))
  • TRAP. An election made under the first-year-of-eligibility exception applies only to compensation for services after the election date. Compensation earned before the election date but payable in a subsequent year cannot be covered by this exception and remains subject to the prior-year rule.
• Subsequent deferral elections. A plan that permits a subsequent election to delay or change the form of payment must satisfy a three-prong test. (Treas. Reg. § 1.409A-2(b))
  • Prong 1 - 12-month delay. The election may not take effect until at least 12 months after the date on which the election is made.
  • Prong 2 - 5-year additional deferral. The payment must be deferred for a period of not less than 5 years from the date the payment would otherwise have been paid. (Treas. Reg. § 1.409A-2(b)(1)(ii))
  • Prong 3 - 12-month lookback. The election must be made at least 12 months before the first scheduled payment date (for specified time or fixed schedule payments). (Treas. Reg. § 1.409A-2(b)(1)(iii))
  • Exception to the 5-year rule. The 5-year additional deferral requirement does not apply to elections related to payments on account of disability, death, or unforeseeable emergency. (Treas. Reg. § 1.409A-2(b)(1)(ii))
  • TRAP. The 5-year rule applies to each installment separately if installments are treated as separate payments. If installments are treated as a single payment (the default), the 5-year deferral is measured from the first scheduled installment.
• Permissible payment events. A plan may provide that deferred compensation may be paid only upon one of six events. (Treas. Reg. § 1.409A-3(a))
  • Separation from service (subject to the six-month delay for specified employees). (Treas. Reg. § 1.409A-3(a)(1))
  • Disability. (Treas. Reg. § 1.409A-3(a)(2))
  • Death. (Treas. Reg. § 1.409A-3(a)(3))
  • A specified time or pursuant to a fixed schedule. (Treas. Reg. § 1.409A-3(a)(4))
  • A change in control event. (Treas. Reg. § 1.409A-3(a)(5))
  • The occurrence of an unforeseeable emergency. (Treas. Reg. § 1.409A-3(a)(6))
  • TRAP. An initial public offering is NOT a permissible payment event under § 409A. Plans that provide for payment upon IPO must be restructured to use a permissible event.
  • CAUTION. A plan must designate a payment date that is "objectively determinable and nondiscretionary at the time the event occurs." (Treas. Reg. § 1.409A-3(i)(1)) Vague timing language such as "when administratively practicable" without a specified outer limit may cause an operational failure.
• Prohibition on acceleration. No plan may permit the acceleration of the time or schedule of any payment, and no accelerated payment may be made whether or not provided for under the plan. (Treas. Reg. § 1.409A-3(i)(1))
  • The prohibition applies both to plan terms (the document may not permit acceleration) and to actual payments (no accelerated payment may be made even if not authorized).
  • Permissible accelerations under § 1.409A-3(j)(4). Limited regulatory exceptions include (Treas. Reg. § 1.409A-3(j)(4))
    • Limited cashouts (lump sum not exceeding the § 402(g) limit, terminating the entire interest under the plan). (§ 1.409A-3(j)(4)(v))
    • Payment of FICA and other employment taxes. (§ 1.409A-3(j)(4)(vi))
    • Payment of state, local, and foreign taxes. (§ 1.409A-3(j)(4)(xi))
    • Payment upon income inclusion under § 409A (when the plan fails). (§ 1.409A-3(j)(4)(vii))
    • Domestic relations orders. (§ 1.409A-3(j)(4)(ii))
    • Bona fide disputes as to right to payment. (§ 1.409A-3(j)(4)(xiv))
    • Certain offsets (up to $5,000 per taxable year). (§ 1.409A-3(j)(4)(xiii))
    • Plan terminations and liquidations under the three scenarios in § 1.409A-3(j)(4)(ix). (§ 1.409A-3(j)(4)(ix))
• Change in control events. Three types of change in control events are permissible. (Treas. Reg. § 1.409A-3(i)(5))
  • Type 1. Change in ownership. One person or more than one person acting as a group acquires stock constituting more than 50% of the total fair market value or total voting power of the corporation. (Treas. Reg. § 1.409A-3(i)(5)(v))
  • Type 2. Change in effective control. Either (A) any person or group acquires ownership of stock possessing 30% or more of the total voting power of the corporation, or (B) a majority of the board of directors is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the pre-existing board. (Treas. Reg. § 1.409A-3(i)(5)(vi))
  • Type 3. Change in ownership of substantial assets. One person or group acquires during a 12-month period assets having a total gross fair market value equal to or exceeding 40% of the total gross fair market value of all assets of the corporation immediately prior to the acquisition. (Treas. Reg. § 1.409A-3(i)(5)(vii))
  • The plan definition can be narrower than the regulatory default but cannot be broader. A plan that defines change in control more expansively than the regulatory safe harbors fails § 409A.
• Separation from service definition. An employee separates from service upon death, retirement, or termination of employment. (Treas. Reg. § 1.409A-1(h)(1)(i))
  • The 20%/50% presumption test applies. Service at 20% or less of the prior 36-month average creates a rebuttable presumption of separation. Service at 50% or more creates a rebuttable presumption of no separation. Between 20% and 50%, no presumption applies and facts and circumstances govern. (Treas. Reg. § 1.409A-1(h)(1)(ii))
  • A plan may designate a specific percentage between 20% and 50% as the separation threshold, provided the percentage is specified in writing. (Treas. Reg. § 1.409A-1(h)(1)(ii))
  • The employment relationship continues during military leave, sick leave, or other bona fide leave of absence not exceeding 6 months (or longer if the individual retains a reemployment right). (Treas. Reg. § 1.409A-1(h)(1)(iii))
  • CAUTION. A transition from employee to independent contractor may or may not constitute a separation from service depending on the facts. If the service provider continues to provide significant services at a reduced level, the separation from service analysis under the 20%/50% test must be performed.

Step 13. § 409A Correction Programs

"This notice [Notice 2008-113] provides guidance regarding the correction of certain operational failures of a nonqualified deferred compensation plan to comply with § 409A(a)." IRS Notice 2008-113, 2008-51 I.R.B. 1305.

"This notice [Notice 2010-6] provides methods for taxpayers to voluntarily correct certain failures to comply with the document requirements applicable under § 409A(a)." IRS Notice 2010-6, 2010-3 I.R.B. 275.

• Document failures versus operational failures. Document failure means a provision in the written plan document that fails to comply with § 409A. Operational failure means the plan document complies but the plan was not operated in accordance with its terms or with § 409A requirements due to inadvertent and unintentional errors. (Notice 2010-6) (Notice 2008-113, § II)
  • Document failure examples include a plan that omits the six-month delay for specified employees, defines disability more broadly than the § 409A standard, or includes an impermissible payment event.
  • Operational failure examples include paying a specified employee within 6 months of separation, accepting a late deferral election, or making a payment on an impermissible event even though the plan does not authorize it.
  • Critical distinction. The plan aggregation rules do NOT apply to written plan requirement failures. (Treas. Reg. § 1.409A-1(c)(3)(viii)) An operational failure in one plan DOES trigger aggregation and taints all plans in the same category (as determined in Step 5).
• Notice 2010-6 (document failure correction). Notice 2010-6 provides several correction methods. (Notice 2010-6, § III)
  • Standard correction. If the corrected provision does not affect plan operation within one year of correction, no income inclusion or additional taxes are required. If a payment event occurs within one year, the service provider includes a specified percentage of the deferred amount in income (typically 50%, or 25% for change in control definition failures), pays the 20% additional tax on the included amount, but does not owe the premium interest tax. (Notice 2010-6, §s V through VIII)
  • Plan-to-plan transfer correction. For linked plan failures where the time or form of payment under one plan is affected by another plan, correction requires making the time and form of payment identical across the linked plans, retaining the narrower definition of each permissible payment event, and adopting the latest payment schedule. (Notice 2010-6, § XI.B)
  • Plan termination correction. For plans with only impermissible payment events, correction requires replacing the imperissible events with the later of separation from service or the 6th anniversary of the correction date. Immediate inclusion of 50% of the deferred amount is required in the year of correction. (Notice 2010-6, § VII.B)
  • First-plan exception. A service recipient's first plan of a given type may be corrected without income inclusion or additional taxes if corrected within a limited period following adoption. (Notice 2010-6, § X)
  • Transition relief. Document failures corrected on or before December 31, 2010 (and related operational failures corrected under Notice 2008-113 by the same date) were eligible for full retroactive relief. This is historical but may be relevant for audit of pre-2010 arrangements. (Notice 2010-6, § III.C)
• Notice 2008-113 (operational failure correction). Four categories of correction. (Notice 2008-113, §s IV through VII)
  • Category A (same-year correction). If an unintentional operational failure is corrected during the same taxable year in which it occurs, no amount is required to be included in income under § 409A(a). The service provider must generally repay erroneous payments. The service recipient must take commercially reasonable steps to avoid recurrence. (Notice 2008-113, § IV)
  • Category B (next-year non-insider correction). If correction occurs in the taxable year immediately following the failure year, no § 409A tax or penalty applies, but only for non-insider service providers. Insiders are not eligible for this category. Erroneous payments must be repaid with interest at the short-term applicable federal rate. (Notice 2008-113, § V)
  • Category C (limited-amount relief). For operational failures involving amounts not exceeding the § 402(g) limit on elective deferrals for qualified plans ($23,500 for 2025), corrected by the end of the 2nd taxable year following the failure year. Income inclusion is limited to the amount involved in the failure (not all deferred amounts under the plan). The 20% additional tax applies but not the premium interest tax. (Notice 2008-113, § VI)
  • Category D (general relief). For other unintentional operational failures corrected by the end of the 2nd taxable year following the failure year. Income inclusion is limited to the amount involved in the failure. The 20% additional tax applies but not the premium interest tax. This category is not available for stock option/SAR strike price failures or for six-month delay violations where payment should have been made in a later taxable year. (Notice 2008-113, § VII)
• Egregious failure exclusion. Neither Notice 2010-6 nor Notice 2008-113 is available for egregious failures. (Notice 2010-6, § II.B) (Notice 2008-113, § III.D)
  • An egregious failure includes but is not limited to (i) a failure that is substantially similar to a failure corrected by the service recipient in a prior taxable year, (ii) a failure that was committed with an intent to defer compensation beyond the period permitted under the plan terms, (iii) a failure to pay employment taxes, and (iv) a pattern of failures.
  • Both notices also exclude intentional failures, failures related to abusive tax avoidance transactions, and failures involving stock right exercises.
• Insider restrictions. Correction relief may be restricted for insiders (officers, directors, and more-than-10% owners) and specified employees. (Notice 2008-113, § III.C) (Notice 2010-6, § II.B)
  • Category B relief (next-year correction with no tax or penalty) is not available to insiders.
  • For document failures, insiders are subject to the same correction framework but may face additional scrutiny regarding the egregious failure determination.
• Correction deadline. Both programs generally require correction by the end of the 2nd taxable year following the taxable year in which the failure occurred. (Notice 2008-113, § III.B) (Notice 2010-6, § II.A)
  • The same-year correction under Category A must occur within the same taxable year as the failure. There is no extension.
  • CAUTION. The correction programs are discretionary administrative guidance. The IRS may modify or terminate them at any time. Do not rely on the existence of correction programs as a substitute for proactive compliance.
• Reporting for corrected failures. When income inclusion is required under either correction program, the employer must report the includible amount on Form W-2 (Box 1 and Box 12 Code Z) or Form 1099-MISC, attach a statement to the employer's federal income tax return describing the correction, and provide the affected service provider with a statement for attachment to their federal income tax return. (Notice 2010-6, § XII) (Notice 2008-113, § IX)
  • Employer statement requirements. The statement attached to the employer's return must identify the plan, describe the nature of the failure, specify the correction method used, state the amount includible in income, and certify that the correction has been completed. The service provider statement must contain substantially similar information to enable the service provider to properly report the includible amount. (Notice 2010-6, § XII) (Notice 2008-113, § IX)
  • Code Z reporting. Box 12 Code Z on Form W-2 reports the total amount of deferred compensation includible in income under § 409A, including both current-year deferrals that fail § 409A and prior-year deferred amounts that become includible due to a failure. Code Z does NOT include the 20% additional tax or premium interest, which the service provider calculates and reports separately on Form 1040. (Notice 2008-115, § IV.B)

Step 14. Reporting, Withholding, and Documentation

"Any amount includible in the gross income of an employee under section 409A is includible as wages under section 3401(a)." Notice 2008-115, 2008-52 I.R.B. 1367.

• Form W-2 reporting (employees). Employers must report § 409A includible amounts in Box 1 (wages, tips, other compensation) of Form W-2. (Notice 2008-115, § IV)
  • Box 12 must include Code Z to separately identify the amount of deferrals and income inclusion under § 409A. (Notice 2008-115, § IV.B)
  • Code Z includes both current-year deferrals that fail § 409A and prior-year deferred amounts that become includible in income due to a § 409A violation.
  • The employer must also report the amounts on Form 941 (employer's quarterly federal tax return).
  • TRAP. The requirement to report annual deferrals on Form W-2 Box 12 Code Y (for deferrals that are not currently includible in income) is currently suspended pending further IRS guidance. Do not report annual deferrals under Code Y unless and until the IRS issues guidance reinstating this requirement. (Notice 2008-115, § IV.D)
• Form 1099 reporting (nonemployees). For nonemployee service providers, the payer must report includible amounts on Form 1099-MISC. (Notice 2008-115, § V)
  • Box 7 (nonemployee compensation) reports the total includible amount.
  • Box 15b reports the § 409A income separately.
  • The parallel Code Y suspension applies to Box 15a for nonemployee deferral reporting.
• Employer income tax withholding. IRC § 3401(a) provides that any amount includible in gross income under § 409A is treated as wages for withholding purposes. (IRC § 3401(a))
  • The employer must withhold income tax on § 409A includible amounts at the supplemental wage rate (22% for supplemental wages under $1 million in a calendar year, 37% for amounts exceeding $1 million). (Treas. Reg. § 31.3402(g)-1)
  • Withholding is required even if no actual payment is made during the year. If the amount is not actually or constructively received during the year, it is deemed paid on December 31 for withholding purposes. (Notice 2008-115, § III.B)
  • The employer is NOT required to withhold the 20% additional tax. The employer is NOT required to withhold the premium interest tax. These are the sole obligation of the service provider. (Notice 2008-115, § III.C)
• Employer liability. IRC § 3403 provides that the employer is liable for the payment of tax required to be deducted and withheld, whether or not collected from the employee. (IRC § 3403)
  • § 6656 penalties apply for failure to deposit withheld taxes on time. The penalty ranges from 2% (deposits 1-5 days late) to 15% (deposits more than 10 days late). (IRC § 6656)
  • § 6721 penalties apply for failure to file correct information returns (Form W-2 or 1099). The penalty is indexed annually (approximately $310 per return for 2024 filings). (IRC § 6721)
  • § 6722 penalties apply for failure to furnish correct payee statements to employees/service providers. The penalty is the same per-return amount as § 6721. (IRC § 6722)
  • CAUTION. An employer who fails to withhold on § 409A includible amounts may be liable for the unpaid withholding tax under § 3403, plus penalties and interest. The employer should establish procedures to identify § 409A income events and process withholding even when no cash payment accompanies the income inclusion.
• State tax conformity. California formerly imposed a parallel 20% state penalty on § 409A violations through its conformity to federal pension rules under Cal. Rev. & Tax. Code § 17501. (Cal. Rev. & Tax. Code § 17501)
  • AB 1173 (2013) reduced the California § 409A penalty from 20% to 5%, effective for taxable years beginning on or after January 1, 2013. (Cal. Rev. & Tax. Code § 17508.2)
  • New York and most other states conform to federal § 409A income inclusion timing without imposing additional state-specific penalties.
  • For California residents, the combined federal and state penalty on a § 409A violation is 25% (20% federal + 5% California) plus premium interest, regular federal and state income taxes, and FICA taxes if not previously applied.
• FICA timing interaction. § 3121(v)(2) special timing rule provides that amounts deferred under an NQDC plan are taken into FICA wages at the later of (i) when services are performed, or (ii) when there is no substantial risk of forfeiture (vesting). (IRC § 3121(v)(2)) (Treas. Reg. § 31.3121(v)(2)-1(a)(2))
  • Once amounts are taken into FICA wages under the special timing rule, neither the deferred amount nor any earnings thereon are subject to FICA tax at the future payment date. (Treas. Reg. § 31.3121(v)(2)-1(a)(2)(ii)) This is the non-duplication rule.
  • A § 409A violation causing accelerated income inclusion does NOT trigger additional FICA taxes if the special timing rule was properly applied when the amounts vested.
  • If the employer fails to apply the special timing rule, the general FICA timing rule applies and both the deferred amount and all earnings are included as FICA wages at the time of payment.
  • TRAP. FICA taxes and § 409A operate under entirely separate statutory frameworks. FICA timing is governed by § 3121(v)(2), not § 409A. A § 409A correction does not retroactively alter FICA wage timing.
• Record retention. Maintain all plan documents, election forms, account statements, distribution records, correction documentation, and specified employee lists for at least the period of limitations on assessment. (IRC § 6001) (Rev. Proc. 98-25)
  • The general statute of limitations is 3 years from the date the return was filed. (IRC § 6501(a))
  • If a § 409A failure occurs, retain records relating to the failure and correction for at least 3 years after the return for the correction year is filed.
  • Best practice is to retain plan documents and election forms indefinitely, since benefits may be payable decades after the deferral right arises and the statute may remain open if no return was filed or if there is a substantial omission of income.
• Annual compliance best practices.
  • Conduct an annual § 409A compliance audit covering all compensation arrangements. Review each arrangement for § 409A coverage (Step 1), determine the applicable plan category under the aggregation rules (Step 5), verify written plan documentation (Step 8), and confirm that payment events, election timing, and operational administration comply with the plan terms and § 409A requirements (Step 12).
  • Maintain a master schedule of all compensation arrangements organized by plan category, identifying which documents govern each arrangement and the applicable payment events and timing.
  • Train HR and payroll personnel on § 409A basics, including the prohibition on acceleration, the six-month specified employee delay, and the requirement to follow plan terms exactly.
  • Review all plan documents before and after mergers, acquisitions, and corporate reorganizations. A change in control or corporate restructuring may trigger payment events, alter plan aggregation categories, or cause a plan to terminate and liquidate under § 1.409A-3(j)(4)(ix).
  • Verify specified employee lists annually and confirm that the six-month delay is applied to all separation-from-service payments for affected employees.
  • Document all correction actions contemporaneously, including the date the failure was discovered, the date correction was completed, the method used, and the affected participants.
