M&A Transaction Cost Capitalization (Reg. § 1.263(a)-5; INDOPCO)

This checklist guides the analysis of whether costs incurred in connection with a merger, acquisition, restructuring, or other covered transaction must be capitalized or may be deducted. Use this checklist whenever a client incurs investment banking fees, legal fees, accounting fees, or other professional service costs in connection with any M&A transaction, whether as acquirer, target, or deal participant. The analysis covers the general capitalization framework, the specific categories of transactions subject to Reg. § 1.263(a)-5, the facilitative versus investigatory distinction, the bright-line date rule for covered transactions, inherently facilitative costs, success-based fees and the Rev. Proc. 2011-29 safe harbor, treatment of capitalized costs for acquirers and targets, broken-deal costs, and coordination with § 195 (start-up expenditures) and § 248 (organizational expenditures).

Step 1. The General Capitalization Framework

"Although the mere presence of an incidental future benefit may not warrant capitalization, a taxpayer's realization of benefits beyond the year in which the expenditure is incurred is undeniably important in determining whether the appropriate tax treatment is immediate deduction or capitalization." (INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 86 (1992))

• INDOPCO and the future-benefits test.
  • The Supreme Court held that investment banking fees, legal fees, and miscellaneous expenses incurred by National Starch and Chemical Corporation in connection with its friendly acquisition by Unilever were nondeductible capital expenditures. (INDOPCO, Inc. v. Commissioner, 503 U.S. 79 (1992))
  • National Starch paid Morgan Stanley $2.2 million in fees plus expenses, Debevoise & Plimpton $490,000 in legal fees, and $150,962 in miscellaneous costs for accounting, printing, proxy solicitation, and SEC filings.
  • The acquisition transformed National Starch from a publicly held freestanding corporation into a wholly owned subsidiary of Unilever. The Court found significant long-term benefits including access to Unilever's capital resources, research and development capabilities, marketing network, and operational synergies.
  • The Court rejected National Starch's argument that capitalization requires creation of a "separate and distinct asset." Creation of such an asset is a sufficient condition for capitalization but not a necessary one.
  • The decisive distinction between current expenses and capital expenditures "are those of degree and not of kind," and each case "turns on its special facts." (INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 86 (1992), quoting Welch v. Helvering, 290 U.S. 111, 114 (1933) and Deputy v. Du Pont, 308 U.S. 488, 496 (1940))
  • TRAP. Do not tell a client that a cost is deductible simply because it does not create a separable asset. The "no separate asset" argument lost in INDOPCO and will lose again.
• The origin-of-the-claim doctrine in the M&A context.
  • Expenses incurred in defending title to property or in acquiring property are capital in nature. (Woodward v. Commissioner, 397 U.S. 572 (1970))
  • In Woodward, legal and accounting fees incurred in purchasing a minority stock interest were capital expenditures because the origin of the claim was the acquisition of stock, an inherently capital transaction.
  • Fees incurred in an appraisal proceeding to determine the value of minority stock for compulsory acquisition are capital expenditures. (United States v. Hilton Hotels Corp., 397 U.S. 580 (1970))
  • By contrast, expenses directly related to the employment relationship (such as officer salaries) are only indirectly related to an acquisition and remain deductible as ordinary business expenses. (Wells Fargo & Co. v. Commissioner, 224 F.3d 874 (8th Cir. 2000))
• The Lincoln Savings "separate and distinct asset" test as a sufficient but not necessary condition.
  • Commissioner v. Lincoln Savings & Loan Assn., 403 U.S. 345 (1971) held that an additional premium paid to the FSLIC that created a separate and distinct asset (a pro rata interest in the Secondary Reserve) was a capital expenditure.
  • The Court stated that "the presence of an ensuing benefit that may have some future aspect is not controlling. Many expenses concededly deductible have prospective effect beyond the taxable year."
  • After INDOPCO, the "separate and distinct asset" test remains relevant but is no longer the exclusive test. Practitioners must analyze both whether a separate asset is created AND whether significant future benefits extend beyond the taxable year. (INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 84-87 (1992))

Step 2. The Scope of Reg. § 1.263(a)-5

"A taxpayer must capitalize an amount paid to facilitate each of the following transactions, without regard to whether the transaction is comprised of a single step or a series of steps carried out as part of a single plan and without regard to whether gain or loss is recognized in the transaction." (Treas. Reg. § 1.263(a)-5(a))

• General rule of mandatory capitalization.
  • Reg. § 1.263(a)-5 requires capitalization of amounts paid to facilitate nine categories of transactions listed in paragraphs (a)(1) through (a)(10). The rule applies even if no gain or loss is recognized and even if the transaction involves multiple steps carried out as part of a single plan.
  • The regulation applies to costs paid or incurred in taxable years beginning on or after December 19, 2003. For costs incurred before that date, the common law INDOPCO analysis governs. (Treas. Reg. § 1.263(a)-5(m))
  • CAUTION. The regulation uses the word "facilitate" as its operative term. A cost facilitates a transaction if it is paid "in the process of investigating or otherwise pursuing" the transaction. (Treas. Reg. § 1.263(a)-5(b)(1))
• Ordering rules when multiple provisions apply.
  • When both Reg. § 1.263(a)-5 and Reg. § 1.263(a)-4 (amounts paid to acquire or create intangibles) apply to the same cost, the rules of Reg. § 1.263(a)-5 govern the treatment of that cost. (Treas. Reg. § 1.263(a)-5(b)(2))
  • An amount required to be capitalized by Reg. § 1.263(a)-1 (general capitalization), Reg. § 1.263(a)-2 (acquisition of tangible property), or Reg. § 1.263(a)-4 does not "facilitate" a transaction described in Reg. § 1.263(a)-5(a). (Treas. Reg. § 1.263(a)-5(b)(2))
  • EXAMPLE. A cost to acquire an intangible asset (such as a trademark) is capitalized under Reg. § 1.263(a)-4. It is not recharacterized as a facilitative cost under Reg. § 1.263(a)-5 simply because the acquisition occurs as part of a larger transaction.
• Costs that do NOT facilitate a transaction.
  • Costs that result from the transaction but are not incurred to investigate or pursue it do not facilitate the transaction. (Treas. Reg. § 1.263(a)-5(b)(1))
  • Examples include a fee to terminate a management agreement required by an IPO, representation and warranty insurance premiums, and directors' and officers' insurance required by the transaction agreement. These are not facilitative costs but may be capitalizable under other provisions.
  • Costs that are not facilitative and not capitalizable under Reg. § 1.263(a)-5(a) may be deductible as ordinary and necessary business expenses under § 162, capitalizable as start-up expenditures under § 195, or capitalizable under another provision of § 263(a). (Treas. Reg. § 1.263(a)-5(c) introductory text)

Step 3. The Nine Categories of Transactions

• Acquisitions of a trade or business.
  • § 1.263(a)-5(a)(1) covers "an acquisition of assets that constitute a trade or business (whether the taxpayer is the acquirer in the acquisition or the target of the acquisition)."
  • Whether assets constitute a trade or business is determined under the principles of § 1.197-2. Generally, a trade or business is a group of assets capable of being conducted and managed for the purpose of providing a return to investors.
  • § 1.263(a)-5(a)(2) covers "an acquisition by the taxpayer of an ownership interest in a business entity if, immediately after the acquisition, the taxpayer and the business entity are related within the meaning of section 267(b) or 707(b)." For acquisitions where the parties do not become related, Reg. § 1.263(a)-4 governs instead.
  • § 1.263(a)-5(a)(3) covers "an acquisition of an ownership interest in the taxpayer (other than an acquisition by the taxpayer of an ownership interest in the taxpayer, whether by redemption or otherwise)." This is the provision that applies to target-side costs in a stock acquisition.
• Changes in capital structure.
  • § 1.263(a)-5(a)(4) covers "a restructuring, recapitalization, or reorganization of the capital structure of a business entity (including reorganizations described in section 368 and distributions of stock by the taxpayer as described in section 355)."
  • This paragraph captures tax-free reorganizations (Types A through G), spin-offs, split-offs, split-ups, and other divisive transactions under § 355.
  • CAUTION. Costs incurred in connection with a reorganization described in § 368(a)(1)(D) in which stock or securities of the corporation to which assets are transferred are distributed in a transaction qualifying under § 354 or § 356 are treated as a separate category for covered transaction purposes. (Treas. Reg. § 1.263(a)-5(e)(3)(ii))
• Entity formations and contributions.
  • § 1.263(a)-5(a)(5) covers "a transfer described in section 351 or section 721 (whether the taxpayer is the transferor or transferee)."
  • § 1.263(a)-5(a)(6) covers "a formation or organization of a disregarded entity."
  • § 1.263(a)-5(a)(7) covers "an acquisition of capital."
• Stock issuances and borrowings.
  • § 1.263(a)-5(a)(8) covers "an issuance of stock."
  • § 1.263(a)-5(a)(9) covers "an issuance of indebtedness."
  • § 1.263(a)-5(a)(10) covers "a borrowing."
  • Stock issuance costs generally reduce the amount received for the stock (i.e., are treated as a reduction of paid-in capital) rather than being amortized. (Treas. Reg. § 1.248-1(b)(3)) Costs to facilitate a borrowing are generally treated as incurred by the borrower and may be amortized over the term of the loan under § 1.446-5. (Treas. Reg. § 1.263(a)-5(c)(1))

Step 4. Whether Costs Facilitate the Transaction

"The fact that a cost would (or would not) have been paid but for the transaction is relevant, but does not determine whether the amount facilitates the transaction." (Treas. Reg. § 1.263(a)-5(b)(1))

• The facts-and-circumstances inquiry.
  • Whether a cost facilitates a transaction is determined based on all the facts and circumstances. The regulation rejects a pure "but for" test.
  • A cost is facilitative if it is paid "in the process of investigating or otherwise pursuing" the transaction. (Treas. Reg. § 1.263(a)-5(b)(1))
  • Examples of facilitative costs include fees paid to an appraiser to determine the value or purchase price of acquired assets, fees paid to an attorney to assist in executing an IPO, and fees paid to an investment banker to market a bond issuance. (Treas. Reg. § 1.263(a)-5(b)(1))
  • The purchase price of corporate assets or stock is NOT an amount paid to investigate or pursue the transaction and therefore is not a facilitative cost. (Treas. Reg. § 1.263(a)-5(b)(1))
• The "final decision" framework for investigatory costs.
  • Before the bright-line date rule was created, courts distinguished between investigatory costs (incurred to determine whether and which business to enter) and costs to facilitate consummation of a specific acquisition. (Rev. Rul. 99-23, 1999-1 C.B. 998)
  • Rev. Rul. 99-23 established that investigatory costs to determine "whether" to enter a new business and "which" business to enter are eligible for treatment as start-up expenditures under § 195. Costs incurred in the attempt to acquire a specific business are capital in nature and are not start-up expenditures.
  • The "final decision" is the point at which a taxpayer decides whether to acquire a business and which business to acquire, not the point at which the taxpayer and seller are legally obligated to complete the transaction. (Rev. Rul. 99-23)
  • The Eighth Circuit applied this framework in Wells Fargo v. Commissioner, holding that $83,450 of legal expenses Davenport Bank incurred before its "final decision" to merge with Norwest were deductible investigatory costs. The remaining $27,820 incurred after the final decision (the Agreement and Plan of Reorganization on July 22, 1991) were facilitative and had to be capitalized. (Wells Fargo & Co. v. Commissioner, 224 F.3d 874 (8th Cir. 2000))
  • The Wells Fargo court also held that $150,000 of officer salaries were fully deductible because they arose out of the employment relationship and were only indirectly related to the acquisition. (Wells Fargo & Co. v. Commissioner, 224 F.3d 874 (8th Cir. 2000))
  • TRAP. The "final decision" test from Wells Fargo remains relevant for non-covered transactions and for costs incurred before the bright-line date in covered transactions. However, practitioners should not rely on it as a bright-line rule. The court explicitly stated that its determination was fact-specific and "not to be construed as a bright line rule." (Wells Fargo & Co. v. Commissioner, 224 F.3d 874, 884 (8th Cir. 2000))
• Business integration costs do not facilitate the transaction.
  • Integration costs incurred to combine two or more businesses do not facilitate the transaction that resulted in the combined business. (Treas. Reg. § 1.263(a)-5(c)(6))
  • Examples of integration costs include relocating equipment and personnel, combining records and information systems, providing severance benefits to terminated employees, preparing financial statements for the combined entity, and reducing redundancies in combined operations.
  • CAUTION. Integration costs are not facilitative but they may still be capitalizable as ordinary and necessary business expenses if they create or enhance a separate asset. If they do not create an asset, they are generally deductible under § 162.
• Borrowing costs.
  • Costs incurred to facilitate a borrowing are generally treated as incurred by the borrower. Where the loan proceeds and repayment obligation are assumed by a successor, the successor may amortize the capitalized costs over the loan term under § 1.446-5. (Treas. Reg. § 1.263(a)-5(c)(1))

Step 5. Covered Transactions and the Bright-Line Date Rule

Step 5A. What Constitutes a Covered Transaction

• The three types of covered transactions.
  • The bright-line date rule applies only to "covered transactions" described in Treas. Reg. § 1.263(a)-5(e)(3).
  • 1. A taxable acquisition by the taxpayer of assets that constitute a trade or business. (Treas. Reg. § 1.263(a)-5(e)(3)(i))
  • 2. A taxable acquisition of an ownership interest in a business entity if, immediately after the acquisition, the acquirer and target are related within the meaning of § 267(b) or § 707(b). (Treas. Reg. § 1.263(a)-5(e)(3)(ii))
  • 3. A reorganization described in § 368(a)(1)(A), (B), or (C), or a reorganization described in § 368(a)(1)(D) in which stock or securities of the corporation to which assets are transferred are distributed in a transaction qualifying under § 354 or § 356. (Treas. Reg. § 1.263(a)-5(e)(3)(iii))
  • Whether the taxpayer is the acquirer or the target does not matter for covered transaction status.
• Determining related-party status.
  • For § 267(b), key relationships include parent-subsidiary (more than 50% ownership), brother-sister corporations (same persons own more than 50% of each), and certain attribution rules through § 267(c).
  • For § 707(b), the test applies to partnerships and partners where the partner owns more than 50% of capital or profits interests.
  • CAUTION. If the acquisition is of a non-related party's stock, the transaction is NOT a covered transaction and the bright-line date rule does not apply. Instead, all facilitative costs must be capitalized without the pre-bright-line date deduction opportunity.

Step 5B. The Bright-Line Date

"The bright line date is the earlier of (A) the date on which a letter of intent, exclusivity agreement, or similar written communication, other than a confidentiality agreement, is executed by representatives of the acquirer and the target; or (B) the date on which the material terms of the transaction are authorized or approved by the taxpayer's board of directors (or, in the case of a taxpayer that is not a corporation, its governing officials)." (Treas. Reg. § 1.263(a)-5(e)(1))

• Costs incurred BEFORE the bright-line date.
  • Costs incurred before the bright-line date that are NOT inherently facilitative are generally treated as not facilitating the transaction and may be deductible as ordinary and necessary business expenses under § 162. (Treas. Reg. § 1.263(a)-5(e)(1))
  • This is the single most taxpayer-favorable provision in the regulation. It allows deduction of investigatory and due diligence costs incurred early in the process.
  • To take advantage of this rule, taxpayers must maintain documentation showing when services were performed relative to the bright-line date.
• Costs incurred ON OR AFTER the bright-line date.
  • Costs incurred on or after the bright-line date are presumed to facilitate the transaction and must be capitalized unless they fall within an exception or simplifying convention. (Treas. Reg. § 1.263(a)-5(e)(1))
  • This presumption can be rebutted only if the cost falls within a specific exception (such as integration costs, employee compensation, or de minimis costs) or if the taxpayer can demonstrate that the cost was not paid in the process of investigating or otherwise pursuing the transaction.
• Inherently facilitative costs are ALWAYS capitalized regardless of timing.
  • Even if incurred before the bright-line date, inherently facilitative costs must be capitalized. The bright-line date rule does not apply to inherently facilitative amounts. (Treas. Reg. § 1.263(a)-5(e)(2))
• Mutually exclusive transactions.
  • If a taxpayer investigates multiple potential transactions and only some are consummated, costs incurred to facilitate an abandoned transaction that was mutually exclusive with a consummated transaction must be capitalized as facilitating the consummated transaction. (Treas. Reg. § 1.263(a)-5(c)(8))
  • EXAMPLE. If a target pays due diligence costs and a break-up fee related to a potential white knight merger (with LOI dated March 10), but then accepts a competing bidder's offer because the two transactions are mutually exclusive, the white knight due diligence costs and break-up fee are capitalized as facilitating the transaction with the competing bidder. (Treas. Reg. § 1.263(a)-5(l), Example 13)
  • If the transactions are NOT mutually exclusive (e.g., the taxpayer had resources to complete both), costs to facilitate the abandoned transaction may be recovered as a loss under § 165 when the transaction is abandoned. (Treas. Reg. § 1.263(a)-5(l), Example 14)

Step 6. Inherently Facilitative Costs

"An amount is treated as an inherently facilitative amount if the amount is paid for (i) An appraisal or written evaluation or a fairness opinion; (ii) Advice and assistance in structuring the transaction; (iii) Advice and assistance in obtaining regulatory approval of the transaction; (iv) Obtaining shareholder approval of the transaction (including proxy solicitation and promotion costs); (v) Conveying property between the parties to the transaction (including transfer taxes and title registration fees); or (vi) Services performed to investigate or otherwise pursue the transaction, including due diligence costs, provided that the services relate to activities performed after the bright line date." (Treas. Reg. § 1.263(a)-5(e)(2))

• The six categories of inherently facilitative costs.
  • 1. Appraisals, written evaluations, and fairness opinions. (Treas. Reg. § 1.263(a)-5(e)(2)(i)) These must be capitalized regardless of when incurred. Even a fairness opinion obtained during defensive measures against a hostile takeover is inherently facilitative if it relates to the eventual transaction. (Treas. Reg. § 1.263(a)-5(l), Example 11)
  • 2. Advice and assistance in structuring the transaction. (Treas. Reg. § 1.263(a)-5(e)(2)(ii)) This includes tax structuring, entity selection, and transaction architecture.
  • 3. Advice and assistance in obtaining regulatory approval. (Treas. Reg. § 1.263(a)-5(e)(2)(iii)) Includes HSR filings, SEC filings, state regulatory approvals, and antitrust clearance.
  • 4. Obtaining shareholder approval. (Treas. Reg. § 1.263(a)-5(e)(2)(iv)) Includes proxy preparation, solicitation, and promotion costs.
  • 5. Conveying property between the parties. (Treas. Reg. § 1.263(a)-5(e)(2)(v)) Includes transfer taxes, title registration, and deed recording fees.
  • 6. Due diligence and other investigatory services performed after the bright-line date. (Treas. Reg. § 1.263(a)-5(e)(2)(vi)) Pre-bright-line date due diligence is NOT inherently facilitative (it may be deductible), but post-bright-line date due diligence is.
• Inherently facilitative costs and the bright-line date.
  • The bright-line date rule does NOT apply to inherently facilitative costs. These costs must be capitalized even if incurred before the bright-line date. (Treas. Reg. § 1.263(a)-5(e)(2))
  • EXAMPLE. If a target obtains a fairness opinion on January 15 before signing an LOI on March 1, the fairness opinion cost is inherently facilitative and must be capitalized even though it predates the bright-line date. (Treas. Reg. § 1.263(a)-5(l), Example 11)
  • TRAP. Many practitioners mistakenly believe the bright-line date is a universal dividing line for ALL costs. It is not. Inherently facilitative costs are always capitalized.

Step 7. Success-Based Fees and the Documentation Requirement

"A success-based fee is presumed to facilitate the transaction and must be capitalized. A taxpayer may rebut the presumption that the cost facilitates the transaction by providing sufficient documentation to establish that a portion of the fee is allocable to activities that do not facilitate the transaction." (Treas. Reg. § 1.263(a)-5(f))

• The presumption of facilitative status.
  • A success-based fee is any fee that is payable upon the successful closing of a transaction. Investment banking fees structured as a percentage of transaction value payable only at closing are the classic example.
  • The presumption is that 100% of the success-based fee facilitates the transaction and must be capitalized. (Treas. Reg. § 1.263(a)-5(f))
  • The presumption can be rebutted ONLY by maintaining sufficient documentation to establish that some or all of the fee is allocable to activities that do not facilitate the transaction. (Treas. Reg. § 1.263(a)-5(f))
• What constitutes sufficient documentation.
  • The regulation requires "sufficient documentation" but does not specify exact requirements. The practitioner should aim for contemporaneous records that identify specific activities performed and the time allocable to each.
  • Best practices include engagement letters that specify the scope of services, detailed time records from investment bankers showing hours spent on facilitative versus non-facilitative activities, and allocation agreements signed by the service provider.
  • TRAP. The IRS has challenged documentation as insufficient where investment banker allocation letters were prepared after the fact or lacked sufficient detail. CCA 201830011 indicated that a mere letter from the investment banker allocating a percentage of fees may be inadequate without underlying time records.
  • In practice, very few taxpayers maintain documentation robust enough to rebut the presumption successfully. This is precisely why the Rev. Proc. 2011-29 safe harbor was created.
• The practical reality of the documentation requirement.
  • Proving a negative (that activities did NOT facilitate a transaction) is inherently difficult when the fee is contingent on closing.
  • Investment banks typically do not track time by facilitative versus non-facilitative categories. Their engagement letters describe services in general terms.
  • For most practitioners, the analysis should proceed directly to the Rev. Proc. 2011-29 safe harbor. Attempting to rebut the presumption through documentation is rarely successful and invites IRS scrutiny.

Step 8. The Rev. Proc. 2011-29 Safe Harbor

"The Service will not challenge a taxpayer's allocation of a success-based fee between activities that facilitate a transaction described in § 1.263(a)-5(e)(3) and activities that do not facilitate the transaction if the taxpayer treats 70 percent of the amount of the success-based fee as an amount that does not facilitate the transaction, capitalizes the remaining 30 percent as an amount that does facilitate the transaction, and attaches a statement to its original federal income tax return." (Rev. Proc. 2011-29, Section 4.01)

• The 70/30 safe harbor election.
  • Rev. Proc. 2011-29 provides a safe harbor under which 70% of a success-based fee is treated as not facilitating the transaction (generally deductible under § 162 unless another provision such as § 195 applies) and 30% is treated as facilitative (capitalizable).
  • The safe harbor applies ONLY to success-based fees paid in connection with covered transactions described in Treas. Reg. § 1.263(a)-5(e)(3). If the transaction is not a covered transaction, the safe harbor is unavailable.
  • The safe harbor applies to taxable years ending on or after April 8, 2011. (Rev. Proc. 2011-29, § 5)
  • The election is per-transaction and irrevocable. Once made, it applies to ALL success-based fees paid or incurred by the taxpayer in that transaction. (Rev. Proc. 2011-29, § 4.02)
• How to make the election.
  • The election is made by attaching a statement to the taxpayer's ORIGINAL timely-filed federal income tax return (including extensions) for the taxable year in which the success-based fee is paid or incurred. (Rev. Proc. 2011-29, § 4.01(3))
  • The statement must include (1) a statement that the taxpayer is electing the safe harbor, (2) identification of the transaction to which the election relates, and (3) the success-based fee amounts that are deducted (70%) and capitalized (30%).
  • TRAP. The election CANNOT be made on an amended return, a refund claim, or during an IRS examination. If missed, the taxpayer must request 9100 relief under Reg. § 301.9100-3, which requires a $10,000 user fee, a showing of reasonable cause and good faith, and filing before the IRS discovers the failure.
  • The election does not constitute a change in method of accounting. No § 481(a) adjustment is permitted or required. (Rev. Proc. 2011-29, § 4.03)
• The effect of making the safe harbor election.
  • If the election is made, the IRS will not challenge the 70/30 allocation. The taxpayer does not need to maintain documentation showing what portion of the success-based fee facilitated the transaction.
  • The 70% treated as non-facilitative is generally deductible under § 162 as an ordinary and necessary business expense, unless another Code provision overrides the deduction.
  • The 30% treated as facilitative is capitalized under the rules of Reg. § 1.263(a)-5(g). Its subsequent treatment depends on whether the taxpayer is the acquirer or target and whether the transaction is structured as a stock or asset deal. (See Step 11.)
• Interaction with § 195 for acquisition vehicles.
  • If a newly formed entity (such as a merger subsidiary) incurs success-based fees, the 70% treated as non-facilitative may still be subject to § 195 as start-up expenditures if the entity was not engaged in an active trade or business before the transaction.
  • Under § 195(b), start-up expenditures qualify for a $5,000 deduction (phased out dollar-for-dollar when total start-up expenditures exceed $50,000) with the balance amortized over 180 months.
  • CAUTION. For a newly formed acquisition vehicle, the 70% portion may NOT be currently deductible under § 162. It may instead be a capitalizable start-up expenditure under § 195. The safe harbor election affects only the facilitative versus non-facilitative determination under Reg. § 1.263(a)-5. It does not override § 195. (See Step 13.)
  • EXAMPLE. A newly formed acquisition subsidiary pays a $10 million success-based fee. It elects the Rev. Proc. 2011-29 safe harbor. The $7 million (70%) is treated as non-facilitative. However, because the subsidiary is a new entity with no pre-existing trade or business, the $7 million may be a start-up expenditure under § 195, yielding only a $5,000 immediate deduction (assuming the $50,000 phase-out threshold is exceeded) and the balance amortized over 180 months.
• Recent IRS scrutiny of the safe harbor election.
  • In PLR 202308010, the IRS denied a target company's request for 9100 relief to make a late safe harbor election. The IRS concluded that the success-based fee was properly treated as a capitalized cost incurred by the selling shareholders (a private equity fund), not the target corporation.
  • The IRS reasoned that the selling shareholders economically bore the cost of the success-based fee because the purchase price was reduced by the amount of the fee. If the target deducted the fee, the ruling claimed, this would create a double tax benefit by reducing the shareholders' amount realized and the target's taxable income simultaneously.
  • TRAP. The IRS position in PLR 202308010 runs contrary to many prior rulings and common market practice. Taxpayers should (1) always make the safe harbor election on the original timely-filed return, (2) include language in purchase agreements requiring the election, and (3) flag the requirement for tax preparers. If the election is timely and properly made, the IRS cannot raise the "wrong party" issue as a basis for denying the deduction.
  • PLR 202349003 (issued later) granted 9100 relief to a widely held corporation with no controlling shareholder, suggesting the IRS may be focusing its scrutiny on private-equity-sponsored transactions.

Step 9. Special Rules for Specific Cost Types

Step 9A. Employee Compensation

• Employee compensation is generally non-facilitative.
  • Employee compensation (including salaries, wages, bonuses, and commissions) paid to employees of the taxpayer is generally treated as not facilitating a transaction under Reg. § 1.263(a)-5. (Treas. Reg. § 1.263(a)-5(d)(1))
  • This simplifying convention applies regardless of whether the employee works on transaction-related matters. The regulation presumes that employee compensation relates to the employment relationship, not to the transaction.
  • EXAMPLE. A target corporation pays $500,000 in bonuses to employees who worked on the sale process. Under the simplifying convention, this compensation is not facilitative and is deductible as an ordinary business expense (or treated as compensation expense for tax purposes). (Treas. Reg. § 1.263(a)-5(l), Example 5)
  • CAUTION. The simplifying convention does NOT apply to compensation paid to non-employees (such as independent contractors or consultants hired specifically for the transaction). Those payments are analyzed under the general facilitate test.

Step 9B. De Minimis Costs

• De minimis costs of $5,000 or less per transaction.
  • A taxpayer is not required to capitalize amounts paid in the process of investigating or otherwise pursuing a transaction if the amounts in the aggregate do not exceed $5,000. (Treas. Reg. § 1.263(a)-5(d)(3)(i))
  • This de minimis rule is applied on a transaction-by-transaction basis. A taxpayer involved in multiple transactions gets a separate $5,000 de minimis amount for each.
  • If the aggregate costs exceed $5,000, the de minimis exception does not apply to ANY of the costs. It is not a threshold below which only the first $5,000 is excluded. (Treas. Reg. § 1.263(a)-5(d)(3)(i))
  • Commissions paid to a person that is not related to the taxpayer are excluded from the de minimis calculation. (Treas. Reg. § 1.263(a)-5(d)(3)(ii))

Step 9C. Costs of Terminating or Abandoning Transactions

• Termination payments in mutually exclusive transactions.
  • If a taxpayer pays a break-up fee or other termination payment in connection with abandoning a transaction, and the abandoned transaction was mutually exclusive with a consummated transaction, the termination payment facilitates the consummated transaction and must be capitalized. (Treas. Reg. § 1.263(a)-5(c)(8))
  • If the transactions are not mutually exclusive (the taxpayer had resources to complete both), the termination payment does not facilitate the consummated transaction and is not capitalized under Reg. § 1.263(a)-5. (Treas. Reg. § 1.263(a)-5(l), Example 14)
  • TRAP. The mutual exclusivity determination is fact-specific. If the taxpayer could have completed both transactions but chose not to, the break-up fee may not be facilitative. If completing both was impossible (e.g., a target cannot merge with two different acquirers simultaneously), the break-up fee is facilitative of the consummated transaction.

Step 9D. Costs of Defending Against Unwanted Acquisitions

• Defensive measures against hostile takeovers.
  • Legal fees paid to seek an injunction against a hostile takeover are not amounts paid in the process of investigating or otherwise pursuing a transaction with the hostile bidder. They are not facilitative and need not be capitalized. (Treas. Reg. § 1.263(a)-5(l), Example 11)
  • Investment banking fees paid to search for a white knight acquirer are treated differently depending on outcome. If no white knight transaction reaches the bright-line date, the costs are not facilitative. If a white knight transaction reaches the bright-line date, post-bright-line date costs are facilitative. (Treas. Reg. § 1.263(a)-5(l), Example 12)
  • A fairness opinion obtained during the defense against a hostile takeover is inherently facilitative with respect to the eventual transaction and must be capitalized regardless of when obtained. (Treas. Reg. § 1.263(a)-5(l), Example 11)

Step 9E. Registrar, Transfer Agent, and Maintenance Fees

• Routine corporate maintenance fees.
  • Fees paid to a registrar or transfer agent for the maintenance of capital stock records are not treated as amounts that facilitate a stock issuance or other transaction. (Treas. Reg. § 1.263(a)-5(c)(7))
  • This exception applies only to maintenance fees, not to fees paid in connection with a specific issuance, transfer, or transaction.

Step 10. Simplifying Conventions

• Employee compensation exclusion.
  • As described in Step 9A, employee compensation is generally not treated as facilitative. (Treas. Reg. § 1.263(a)-5(d)(1))
  • "Employee compensation" includes amounts treated as employee compensation for federal income tax withholding purposes, such as certain golden parachute payments and certain director fees. (Treas. Reg. § 1.263(a)-5(d)(2))
  • This exclusion does NOT apply to compensation paid to non-employees or to success-based fees paid to investment bankers.
• Election to capitalize.
  • A taxpayer may elect to capitalize amounts that are not required to be capitalized under Reg. § 1.263(a)-5. (Treas. Reg. § 1.263(a)-5(d)(4))
  • This election is made by capitalizing the amounts on the taxpayer's timely-filed federal income tax return for the taxable year in which the amounts are paid or incurred.
  • Once made, the election is irrevocable and applies to all similar amounts in the transaction.
  • The election to capitalize is rarely advantageous but may be useful in specific planning scenarios.
• The simplifying conventions and covered transactions.
  • The simplifying conventions apply to covered transactions and non-covered transactions alike. However, they are most valuable in the covered transaction context because they allow deduction of costs that might otherwise be capitalized under the bright-line date rule.
  • EXAMPLE. A target pays $1 million in employee bonuses to employees who worked long hours during a six-month sale process. Under the employee compensation simplifying convention, the entire $1 million is not facilitative and is deductible (or treated as compensation expense), even though the employees were directly involved in facilitating the sale.

Step 11. Treatment of Capitalized Costs for Acquirers and Targets

"In the case of an acquisition, merger, or consolidation that is not described in section 368, an amount required to be capitalized under this section by the acquirer is added to the basis of the acquired assets (in the case of a transaction that is treated as an acquisition of the assets of the target for federal income tax purposes) or the acquired stock (in the case of a transaction that is treated as an acquisition of the stock of the target for federal income tax purposes)." (Treas. Reg. § 1.263(a)-5(g)(2)(i))

Step 11A. Acquirer Treatment

• Acquirer in a taxable asset acquisition.
  • Capitalized costs are added to the basis of the acquired assets. They are depreciable or amortizable over the applicable recovery periods of the underlying assets.
  • If the acquisition is treated as an asset acquisition for tax purposes (including a deemed asset acquisition under § 338(h)(10)), the acquirer recovers the capitalized costs through depreciation and amortization.
  • Costs should be allocated among the acquired assets under the residual method of § 1060. Costs specifically traceable to particular assets (such as appraisal costs allocated to specific property) are added to the basis of those assets. General costs (such as investment banking fees) are treated as part of the purchase price and allocated among all acquired assets.
• Acquirer in a taxable stock acquisition (without a § 338 election).
  • Capitalized costs are added to the basis of the acquired stock. (Treas. Reg. § 1.263(a)-5(g)(2)(i))
  • Stock is a capital asset under § 1221. Capitalized costs added to stock basis are NOT depreciable or amortizable. They create "dead basis" that is recovered only upon a taxable disposition of the stock.
  • TRAP. This is the worst possible tax treatment for transaction costs. The acquirer receives no current tax benefit from costs that may total millions of dollars. Recovery is deferred until the stock is sold, and any resulting loss is a capital loss subject to the limitations of § 1211.
  • TAM 202004010 confirms this treatment. The IRS ruled that target-side facilitative costs capitalized by an acquirer in a taxable reverse triangular merger did NOT create a separately identifiable intangible asset under § 1.263(a)-4(b)(3)(i). The costs were governed by § 1.263(a)-5 and remained capitalized without amortization for the life of the target's business enterprise.
  • Practitioners should consider structuring acquisitions as asset purchases or making § 338(h)(10) elections to convert non-amortizable stock basis into depreciable asset basis.

Step 11B. Target Treatment

• Target in a taxable asset acquisition.
  • Capitalized costs are treated as a reduction of the target's amount realized on the disposition of its assets. (Treas. Reg. § 1.263(a)-5(g)(2)(ii)(A))
  • This is the best possible tax treatment. The target recovers capitalized costs immediately by offsetting gain on the asset sale.
  • EXAMPLE. Target sells assets with a basis of $50 million for $100 million, realizing $50 million of gain. Target has $5 million in capitalized facilitative costs. The $5 million reduces the amount realized to $95 million, reducing the recognized gain to $45 million. Target effectively deducts the $5 million at ordinary capital gains rates.
• Target in a taxable stock acquisition.
  • Treas. Reg. § 1.263(a)-5(g)(2)(ii)(B) expressly RESERVES on the treatment of target costs in a taxable stock acquisition.
  • Because the regulation is reserved, there is no definitive IRS guidance on this issue.
  • Common practitioner positions include (1) treating the costs as a non-amortizable intangible asset that may be written off upon complete liquidation of the target, (2) claiming a § 165 loss deduction when the target's stock becomes worthless, or (3) in certain consolidated return contexts, recovering the costs through the investment adjustment rules of § 1.1502-32.
  • CAUTION. The lack of clear guidance creates audit risk. The IRS may argue that capitalized target costs in a stock acquisition create a non-amortizable intangible similar to the acquirer stock basis treatment. Alternatively, the IRS may argue that target costs should reduce the amount realized by the selling shareholders on the sale of their stock, which would be unfavorable to the target.
  • TAM 202004010 addressed a specific fact pattern (reverse triangular merger) but did not resolve the general question of how targets should treat capitalized costs in taxable stock acquisitions.

Step 12. Broken Deal and Abandoned Transaction Costs

• General rule for abandoned transactions.
  • Capitalized costs of an abandoned transaction are recoverable as losses under § 165 in the taxable year the transaction is terminated or abandoned. (Treas. Reg. § 1.263(a)-5(l), Examples 3 and 4)
  • This rule applies only to costs that were previously capitalized under Reg. § 1.263(a)-5. Costs that were deducted (such as pre-bright-line date investigatory costs in a covered transaction) are already reflected in income and do not generate a loss on abandonment.
  • The character of the loss depends on what was abandoned. For costs that facilitated an acquisition of assets or stock, the loss may be a capital loss if it is treated as attributable to the abandonment of a capital asset.
• § 1234A and termination fees.
  • § 1234A provides that gain or loss from the cancellation, lapse, expiration, or other termination of a right or obligation with respect to property that is (or would be) a capital asset in the hands of the taxpayer is treated as gain or loss from the sale of a capital asset.
  • The IRS has historically taken the position that break-up fees and termination fees paid in connection with failed M&A transactions are subject to § 1234A and therefore give rise to capital loss.
  • In AbbVie Inc. v. Commissioner, 164 T.C. No. 10 (2025), the Tax Court rejected the IRS position. AbbVie paid a $1.635 billion break fee after its board withdrew support for a proposed merger with Shire plc. The IRS argued the fee was a capital loss under § 1234A. The Tax Court held for AbbVie, finding that the Cooperation Agreement was fundamentally a services agreement, not a right or obligation with respect to property.
  • The AbbVie court reasoned that a right or obligation "with respect to property" within the meaning of § 1234A is a right or obligation to exchange (to buy, sell, or otherwise transfer or receive) an interest in property. AbbVie's obligations under the Cooperation Agreement were to perform services (secure regulatory approvals, recommend the merger to shareholders, provide information), not to transfer property.
  • The court also noted that AbbVie and Shire did not own their own shares. The power to transfer shares rested with public shareholders, regulators, and courts. The Agreement did not give either company the power to transfer property.
  • In February 2026, the IRS dropped its appeal of AbbVie, leaving the Tax Court decision intact.
  • TRAP. AbbVie is fact-specific. The result may differ if the break fee is paid by a party that actually owns the property subject to the transaction (such as a selling shareholder who owns the target stock). Practitioners should analyze whether the agreement creates a right or obligation to transfer property or merely to perform services.
  • CAUTION. Even if § 1234A does not apply, a break fee is not automatically deductible under § 162. The regulation requires break fees to be capitalized if the payer is terminating one transaction to enter into another mutually exclusive transaction. (Treas. Reg. § 1.263(a)-5(c)(8))
• Mutually exclusive transactions and abandonment losses.
  • If a taxpayer capitalizes costs to facilitate multiple potential transactions and abandons some but not others, the treatment depends on whether the transactions are mutually exclusive.
  • If the abandoned transaction was mutually exclusive with a consummated transaction, the abandoned costs must be capitalized as facilitating the consummated transaction and are NOT recoverable as losses. (Treas. Reg. § 1.263(a)-5(c)(8))
  • If the abandoned transaction was NOT mutually exclusive with a consummated transaction, the capitalized costs of the abandoned transaction are recoverable as losses under § 165 in the year of abandonment. (Treas. Reg. § 1.263(a)-5(l), Example 4)
  • EXAMPLE. Corporation R investigates acquiring three targets (T, U, and V). R reaches the bright-line date only with T and abandons U and V. Because the acquisitions are not mutually exclusive, R may recover the capitalized costs of investigating U and V as losses under § 165. (Treas. Reg. § 1.263(a)-5(l), Example 4)
  • EXAMPLE. Same facts, but R executes a letter of intent with white knight W and pays a break-up fee when it instead accepts Z's offer. Because R cannot merge with both W and Z, the white knight costs and break-up fee are capitalized as facilitating the Z transaction. (Treas. Reg. § 1.263(a)-5(l), Example 13)

Step 13. Coordination with § 195 (Start-Up Expenditures)

"The term 'start-up expenditure' means any amount paid or incurred in connection with (A) investigating the creation or acquisition of an active trade or business, or (B) creating an active trade or business." (§ 195(c)(1))

• What qualifies as a start-up expenditure.
  • § 195(c)(1)(A) defines start-up expenditures as amounts paid or incurred in connection with investigating the creation or acquisition of an active trade or business.
  • To qualify, the expenditure must also satisfy § 195(c)(1)(B). It must be an amount that "if paid or incurred in connection with the operation of an existing active trade or business by the taxpayer, would be allowable as a deduction for the taxable year in which paid or incurred."
  • Critically, § 195(c)(1)(B) excludes "amounts paid or incurred as part of the acquisition cost of a trade or business." Acquisition costs are capital expenditures under § 263(a), not start-up expenditures.
• The "whether and which" versus "consummation" distinction.
  • Rev. Rul. 99-23 establishes the dividing line. Expenditures incurred in the course of a general search or investigation to determine whether to enter a new business and which new business to enter qualify as investigatory costs eligible for § 195 amortization.
  • Expenditures incurred in the attempt to acquire a specific business do NOT qualify as start-up expenditures because they are acquisition costs under § 263(a). (Rev. Rul. 99-23, 1999-1 C.B. 998)
  • The "final decision" is the point at which the taxpayer decides whether to acquire a business and which business to acquire, not the point of legal obligation. (Rev. Rul. 99-23)
  • Preliminary due diligence services (research on the target's industry, review of financial projections) incurred BEFORE the decision to acquire a specific target are investigatory costs eligible for § 195.
  • Due diligence services provided AFTER that decision (reviewing internal documents, books and records, drafting acquisition agreements) are capital costs to facilitate consummation and are NOT § 195 expenditures. (Rev. Rul. 99-23)
  • The label that the parties use to describe the cost and the timing of payment do not necessarily determine the nature of the cost. (Wells Fargo & Co. v. Commissioner, 224 F.3d 874 (8th Cir. 2000), citing Rev. Rul. 99-23)
• The § 195 amortization election.
  • Under § 195(b), a taxpayer may elect to deduct start-up expenditures up to $5,000. This $5,000 amount is reduced dollar-for-dollar when total start-up expenditures exceed $50,000. (§ 195(b)(1)(A))
  • The balance of start-up expenditures is amortized ratably over 180 months (15 years) beginning with the month in which the active trade or business begins. (§ 195(b)(1)(B))
  • If the taxpayer does not make the election, the start-up expenditures are capitalized but are not amortizable until the business begins. If the business never begins, the expenditures may be deductible as a loss under § 165 when the project is abandoned.
  • TRAP. The § 195 election is made by attaching a statement to the taxpayer's timely-filed return for the year the trade or business begins. Unlike the Rev. Proc. 2011-29 safe harbor, there is no 9100 relief available for a missed § 195 election.
• Interaction with Reg. § 1.263(a)-5 for covered transactions.
  • Costs incurred before the bright-line date in a covered transaction that are not inherently facilitative may be deductible under § 162 as ordinary business expenses. (Treas. Reg. § 1.263(a)-5(e)(1))
  • If the taxpayer is a new entity with no existing trade or business, those same pre-bright-line date costs may instead be start-up expenditures under § 195. The practical difference is often minimal because both § 162 and § 195 generally allow current or near-current deduction.
  • Costs incurred on or after the bright-line date are facilitative and must be capitalized under § 263(a). They cannot be § 195 start-up expenditures because they are "paid or incurred as part of the acquisition cost of a trade or business." (§ 195(c)(1)(B))
  • CAUTION. For a newly formed acquisition vehicle, even the 70% of a success-based fee treated as non-facilitative under Rev. Proc. 2011-29 may be subject to § 195 rather than § 162. Because the new entity has no existing trade or business, the non-facilitative costs may be start-up expenditures rather than currently deductible ordinary expenses.
• New holding company structures.
  • When a new holding company is formed to acquire a target, costs the holding company incurs to investigate the acquisition may be § 195 start-up expenditures if incurred before the acquisition is consummated.
  • After the acquisition, the holding company may be considered to have begun an active trade or business (through the acquired subsidiary). Start-up expenditure amortization begins in the month the business begins.
  • TRAP. If the holding company is a passive investment entity that does not actively operate the acquired business, the Service may argue that the holding company has not begun an active trade or business and therefore § 195 amortization has not commenced.

Step 14. Coordination with § 248 (Organizational Expenditures)

• The scope of organizational expenditures.
  • § 248 allows a corporation to elect to deduct organizational expenditures. Under § 248(a), the corporation may deduct up to $5,000 (reduced dollar-for-dollar when expenditures exceed $50,000) in the taxable year the business begins, with the balance amortized over 180 months. (§ 248(a))
  • Organizational expenditures are defined in Treas. Reg. § 1.248-1(b) as expenditures that meet ALL of the following tests.
  • 1. Incident to the creation of the corporation.
  • 2. Chargeable to the capital account.
  • 3. Of a character that, if expended incident to the creation of a corporation having a limited life, would be amortizable over such life.
• What qualifies as an organizational expenditure.
  • Examples include legal services incident to organizing the corporation (drafting the charter, bylaws, minutes of organizational meetings, terms of original stock certificates), necessary accounting services, expenses of temporary directors and of organizational meetings, and fees paid to the state of incorporation. (Treas. Reg. § 1.248-1(b)(2))
• What does NOT qualify.
  • Expenditures connected with issuing or selling shares of stock or other securities (commissions, professional fees, printing costs) are NOT organizational expenditures. They reduce the amount received for the stock. (Treas. Reg. § 1.248-1(b)(3))
  • Expenditures connected with the transfer of assets to a corporation are NOT organizational expenditures. (Treas. Reg. § 1.248-1(b)(3))
  • Expenditures connected with the reorganization of a corporation are NOT organizational expenditures unless directly incident to the creation of a corporation. (Treas. Reg. § 1.248-1(b)(3))
• Distinction from Reg. § 1.263(a)-5 and § 195.
  • § 248 applies to costs of creating the corporation itself (charter, bylaws, organizational meetings). It does NOT apply to costs of investigating, negotiating, or consummating an acquisition.
  • § 195 applies to investigatory costs of acquiring a trade or business. Reg. § 1.263(a)-5 applies to facilitative costs of consummating an acquisition.
  • In a typical acquisition structure, three different provisions may apply to three different categories of costs incurred by a new acquisition vehicle.
  • 1. Organizational costs (charter, bylaws) are § 248 expenditures.
  • 2. Pre-bright-line date investigatory costs are § 195 start-up expenditures.
  • 3. Post-bright-line date facilitative costs are capitalized under § 263(a).
• Practical guidance for acquisition vehicles.
  • When forming a merger subsidiary or acquisition vehicle, separately track (1) costs to organize the entity, (2) costs to investigate the acquisition, and (3) costs to consummate the acquisition.
  • The same $5,000 immediate deduction limit applies to both § 195 and § 248, but they are calculated separately. A new corporation could potentially deduct up to $10,000 immediately ($5,000 under § 195 and $5,000 under § 248) if it has qualifying expenditures under both provisions.
  • CAUTION. Do not include stock issuance costs or acquisition negotiation costs as organizational expenditures. The IRS will recharacterize them, potentially resulting in disallowed deductions and penalties.

Step 15. Recovery of Capitalized Costs Through Basis, Amortization, and Depreciation

• Recovery path depends on transaction structure and party role.
  • The table below summarizes how capitalized costs are recovered. This is a critical planning consideration because the same $10 million in transaction costs can produce dramatically different tax outcomes depending on structure.
  • Acquirer in asset acquisition. Costs are added to asset basis and recovered through depreciation (§ 168 for tangible property, § 197 for intangibles over 15 years). Recovery period ranges from 3 to 39 years for tangible assets and is uniformly 15 years for § 197 intangibles including goodwill.
  • Acquirer in stock acquisition (no § 338). Costs are added to stock basis and are NOT recoverable until the stock is sold. This is "dead basis" that produces no amortization or depreciation deductions. Any loss on sale is a capital loss subject to § 1211 limitations.
  • Acquirer in stock acquisition (with § 338(h)(10)). Costs are added to AGUB and allocated to deemed purchased assets. They are recovered through depreciation and amortization like an asset acquisition.
  • Target in asset acquisition. Costs reduce amount realized on the asset sale. Target recovers costs immediately by offsetting gain. This is the most favorable treatment.
  • Target in stock acquisition. Reserved in the regulations. The target may recover costs upon a § 165 loss event (worthlessness, liquidation) or through consolidated return investment adjustments.
• The § 197 intangible framework.
  • § 197 requires amortization of "section 197 intangibles" over 15 years using the straight-line method, beginning in the month of acquisition. (§ 197(a))
  • § 197 intangibles include goodwill, going concern value, workforce in place, information base, know-how, customer-based intangibles, supplier-based intangibles, licenses, covenants not to compete, franchises, trademarks, and trade names. (§ 197(d) and (f))
  • When transaction costs are added to the basis of acquired assets under § 1060, they are allocated among the seven asset classes. Costs allocated to Class VII (goodwill and going concern value) are amortized over 15 years under § 197.
  • TRAP. Self-created intangibles are generally excluded from § 197. However, this exclusion does not apply to intangibles created in connection with a transaction subject to § 1060 (an applicable asset acquisition). Thus, goodwill created in an asset acquisition is a § 197 intangible even though it is newly created.
• The § 338 deemed asset purchase framework.
  • If a qualified stock purchase is accompanied by a § 338 election (or § 338(h)(10) election), the stock acquisition is treated as a deemed asset purchase. (§ 338(a))
  • The acquirer's costs are added to AGUB (adjusted grossed-up basis). The target's costs reduce the amount realized on the deemed asset sale.
  • AGUB is allocated among the deemed purchased assets under the residual method of § 1060. Costs allocated to tangible assets are depreciated under § 168. Costs allocated to § 197 intangibles are amortized over 15 years.
  • A § 338(h)(10) election converts otherwise non-amortizable stock basis into depreciable asset basis. This is often the single most valuable tax planning technique for transaction cost recovery.
  • CAUTION. A § 338(h)(10) election requires agreement between buyer and seller. The seller must recognize gain or loss on the deemed asset sale, which may create adverse tax consequences. The election is not available in all transactions.
• Economic performance and timing of deductions.
  • For accrual-method taxpayers, success-based fees are not deductible until the "all-events test" is satisfied and economic performance has occurred. (§ 461(h))
  • A success-based fee is contingent on closing. Until the transaction closes, the liability is not fixed and the all-events test is not satisfied.
  • If a transaction straddles the taxable year end, the success-based fee is not deductible until the year of closing (assuming the safe harbor election is made in that year).
  • TRAP. For transactions closing in January of Year 2, the success-based fee is deductible in Year 2 even though services were performed throughout Year 1. This timing rule can create ASC 740 book-tax differences because the costs are typically accrued for book purposes in Year 1.

Step 16. Economic Substance, Business Purpose, and Anti-Abuse Considerations

• The transaction cost analysis assumes a bona fide transaction.
  • Reg. § 1.263(a)-5 applies to costs incurred in connection with transactions described in the regulation. If the transaction lacks economic substance or business purpose, the transaction cost analysis may be irrelevant because the purported transaction is disregarded for tax purposes.
  • Courts have held that expenses incurred in connection with transactions that lack economic substance are not deductible. (Gregory v. Helvering, 293 U.S. 465 (1935))
  • The economic substance doctrine requires that a transaction (1) have economic substance beyond tax benefits (objective test) and (2) be entered into for a valid business purpose (subjective test). (Codified at § 7701(o) by the Health Care and Education Reconciliation Act of 2010)
  • CAUTION. Economic substance analysis is rarely implicated in ordinary-course M&A transactions. It becomes relevant when the transaction is structured primarily to generate tax benefits with minimal non-tax economic effect.
• Step-transaction doctrine and transaction cost allocation.
  • Under the step-transaction doctrine, formally separate steps may be integrated into a single transaction if they are part of a unified plan.
  • If pre-transaction investigatory costs and post-transaction integration costs are part of a single integrated plan, the IRS may argue that costs incurred at different times should be treated consistently.
  • In most M&A contexts, the step-transaction doctrine does not alter the facilitative versus investigatory analysis because Reg. § 1.263(a)-5 already addresses multi-step transactions ("without regard to whether the transaction is comprised of a single step or a series of steps carried out as part of a single plan").
• Substance-over-form in characterizing costs.
  • The IRS may recharacterize costs based on their substance rather than their label. A cost labeled as "consulting" may be treated as an investment banking fee if it is contingent on closing and compensates the provider for transaction-related services.
  • In PLR 202308010, the IRS looked through the formal structure (target corporation was the contracting party) to the economic substance (selling shareholders bore the cost through a purchase price reduction) and reallocated the success-based fee to the shareholders.
  • TRAP. Parties should ensure that the economic substance of cost allocations matches the formal documentation. Flow of funds should reflect the intended cost allocation. A purchase agreement stating that the target pays a success-based fee while simultaneously reducing purchase price by that fee creates recharacterization risk.
• The INDOPCO legacy for aggressive positions.
  • Before INDOPCO, many taxpayers deducted M&A transaction costs as ordinary business expenses. The Supreme Court's rejection of this position in INDOPCO was a watershed moment.
  • Today, the default rule is clear. Facilitative costs must be capitalized. The only exceptions are those explicitly provided in the regulation (bright-line date rule for covered transactions, simplifying conventions, and the Rev. Proc. 2011-29 safe harbor).
  • Practitioners should not take aggressive positions that treat clearly facilitative costs as deductible. The IRS actively examines transaction cost deductions, particularly success-based fees.

Step 17. State Tax Conformity

• General state conformity patterns.
  • Most states that impose corporate income taxes conform to the Internal Revenue Code for the treatment of transaction costs. States that adopt federal taxable income as the starting point for state taxable income generally follow the same capitalization and deduction rules.
  • However, state conformity dates vary. Some states conform to the IRC as of a specific date (rolling or fixed). Others decouple from specific federal provisions or impose their own modifications.
• California.
  • California does not automatically conform to federal capitalization rules. California has historically followed its own rules for the deductibility of business expenses, which may result in different treatment of transaction costs.
  • California generally follows the IRC as of a specific date (updated periodically), but California's Franchise Tax Board may assert independent positions on whether costs should be capitalized or deducted.
  • CAUTION. California's treatment of success-based fees may differ from federal treatment. Taxpayers should verify current California conformity status before assuming the Rev. Proc. 2011-29 safe harbor applies for California purposes.
• New York.
  • New York conforms to federal taxable income but imposes modifications. For example, New York's interest disallowance provisions may affect the treatment of debt financing costs in leveraged acquisitions.
  • New York City has its own corporate tax rules that may decouple from certain federal provisions.
• Texas.
  • The Texas franchise tax (margin tax) is based on taxable margin, not federal taxable income. Texas conforms to the IRC for determining taxable income but applies its own rate and base.
  • Texas updated its IRC conformity for the 2026 report year. Transaction costs that reduce federal taxable income generally reduce Texas margin tax base as well.
• Other state considerations.
  • States that do not conform to the federal covered transaction rules may not recognize the bright-line date rule or the Rev. Proc. 2011-29 safe harbor.
  • Some states have their own capitalization rules that are broader or narrower than Reg. § 1.263(a)-5.
  • TRAP. State tax treatment of transaction costs should be analyzed separately from federal treatment. Do not assume that a deduction allowed for federal purposes is automatically allowed for state purposes.
  • Practitioners should verify the conformity date and any state-specific modifications before preparing state tax returns.
• Local and foreign jurisdiction considerations.
  • Municipal income taxes (such as those imposed by Ohio cities) may have their own rules for the treatment of transaction costs.
  • Foreign jurisdictions may have completely different frameworks for characterizing acquisition costs. Cross-border transactions require separate analysis in each relevant jurisdiction.

Step 18. Documentation and Reporting Obligations

• Contemporaneous documentation requirements.
  • Taxpayers should maintain detailed records of all transaction costs including itemized invoices from service providers, engagement letters specifying the scope of services, board resolutions and minutes approving the transaction, the letter of intent or exclusivity agreement, the purchase agreement, and the flow of funds statement showing who paid each cost.
  • For covered transactions, taxpayers should document the bright-line date (earlier of LOI execution or board approval) and maintain records showing when services were performed relative to that date.
  • For success-based fees, taxpayers should maintain documentation sufficient to establish what portion of the fee is allocable to facilitative versus non-facilitative activities. If the Rev. Proc. 2011-29 safe harbor is elected, no further documentation is required for the 70/30 split.
  • Best practice. Create a transaction cost memorandum contemporaneously with the transaction. The memorandum should identify all costs, categorize them under the regulatory framework, state the bright-line date, document the rationale for each categorization, and be signed off by both the deal team and the tax department.
• Rev. Proc. 2011-29 safe harbor election statement.
  • The election statement must be attached to the taxpayer's original timely-filed federal income tax return (including extensions) for the taxable year the success-based fee is paid or incurred. (Rev. Proc. 2011-29, § 4.01(3))
  • The statement must include
  • 1. A statement that the taxpayer is electing the safe harbor under Rev. Proc. 2011-29.
  • 2. Identification of the transaction to which the election relates (name of target, date of transaction, or other identifying information).
  • 3. The amount of the success-based fee that is treated as not facilitating the transaction (70%) and the amount treated as facilitating (30%).
  • TRAP. Do not wait until the transaction is certain before preparing the election statement. If the return is filed before the transaction closes and the safe harbor is not elected, the election cannot be made on an amended return. Consider protective elections if there is uncertainty about whether a transaction will be a covered transaction.
• Form 3115 for accounting method changes.
  • If a taxpayer has been improperly deducting transaction costs that should have been capitalized (or vice versa), a change in accounting method may be required.
  • Form 3115, Application for Change in Accounting Method, must be filed to obtain IRS consent for most accounting method changes.
  • A § 481(a) adjustment may be required to prevent duplication or omission of items due to the change in method.
  • The IRS has issued automatic consent procedures for certain changes related to transaction costs. Check Rev. Proc. 2024-23 (or current year procedure) for applicable automatic method change numbers.
  • CAUTION. Changes from an impermissible method to a permissible method generally require IRS consent and may trigger a § 481(a) adjustment. Changes from one permissible method to another permissible method may qualify for automatic consent.
• IRS examination readiness.
  • The IRS has identified transaction costs as an area of focus. LB&I and SB/SE examiners are trained to review transaction cost deductions.
  • The IRS Practice Unit "Examining a Transaction Costs Issue" sets forth a three-step framework for examiners. (1) Identify all costs related to the transaction. (2) Determine which costs facilitate a transaction described in Reg. § 1.263(a)-5(a). (3) Apply exceptions and simplifying conventions.
  • Common audit issues include whether the transaction was a covered transaction, whether costs were properly allocated between facilitative and non-facilitative activities, whether the bright-line date was correctly determined, whether inherently facilitative costs were identified, and whether success-based fees were properly documented or the safe harbor election was timely made.
  • If examined, the taxpayer should be prepared to produce all contemporaneous documentation including engagement letters, invoices, board minutes, and the transaction cost study if one was performed.
  • CAUTION. If the IRS challenges a position, penalties may apply if the position lacks reasonable basis. Maintaining thorough documentation strengthens the reasonable basis defense and may help avoid accuracy-related penalties under § 6662.
• Financial statement considerations.
  • Under ASC 805, transaction costs are expensed as incurred by the acquirer for GAAP purposes. This creates a permanent book-tax difference because the same costs are capitalized for tax purposes.
  • The ASC 740 deferred tax accounting for transaction costs depends on (1) which taxpayer is incurring the cost, (2) whether the transaction is an asset or stock acquisition, (3) the income tax treatment of the costs, and (4) the acquirer's tax accounting policy regarding whether the transaction is assumed to close.
  • TRAP. Financial statement auditors may scrutinize the tax treatment of transaction costs because it affects the effective tax rate. Ensure that the book-tax difference is properly documented and supported.
• Final practitioner checklist.
  • Before closing the file, confirm that all of the following have been addressed.
  • 1. All transaction costs have been identified and catalogued.
  • 2. The transaction has been classified under the correct category of Reg. § 1.263(a)-5(a).
  • 3. If a covered transaction, the bright-line date has been determined.
  • 4. Inherently facilitative costs have been identified and segregated.
  • 5. Success-based fees have been analyzed under either the documentation requirement or the Rev. Proc. 2011-29 safe harbor.
  • 6. If the safe harbor was elected, the election statement was attached to the original timely-filed return.
  • 7. The treatment of capitalized costs has been determined for each party (acquirer and target).
  • 8. Coordination with § 195 and § 248 has been analyzed for any new entities.
  • 9. The recovery method (depreciation, amortization, basis, or loss offset) has been identified.
  • 10. State tax conformity has been verified.
  • 11. Contemporaneous documentation has been maintained.
  • 12. The transaction cost memorandum has been completed.
