IRC 280G Golden Parachute Payments: Practitioner Guide

Why IRC 280G Matters in M&A Transactions

IRC 280G is one of the most consequential provisions in M&A tax practice, yet it is frequently underweighted in deal diligence until it is nearly too late to mitigate. The statute disallows the employer's deduction for "excess parachute payments" made to "disqualified individuals" in connection with a change in ownership or control. The companion provision, IRC 4999, imposes a 20% excise tax on the disqualified individual (the executive or key employee) on the same excess parachute payment amount. The result is a double-edged tax cost: the company loses its deduction, and the employee bears a significant excise tax that is not creditable against ordinary income tax liability.

Parachute payment issues arise in virtually every M&A transaction that involves a change in corporate ownership: stock acquisitions, mergers, asset sales structured as deemed stock sales under IRC 338(h)(10), and tax-free reorganizations under IRC 368. Any payment made, or benefit accelerated, to a disqualified individual that is contingent on a change in ownership or control must be analyzed under the IRC 280G framework. The list of payments that qualify is broad: salary continuation, bonus acceleration, accelerated equity vesting, lump-sum consulting agreements, non-compete payments, enhanced severance, and certain retirement benefit enhancements all potentially fall within the statute's scope.

For privately held companies, the shareholder vote safe harbor under Treas. Reg. 1.280G-1 Q&A-7 provides a powerful planning opportunity to avoid the IRC 280G and IRC 4999 costs entirely. For publicly traded companies, no analogous escape valve exists, and planning centers on structuring compensation arrangements to avoid tripping the 3x trigger or to minimize the excess parachute payment amount. The OBBBA's 2025 M&A incentives have contributed to increased deal volume and higher transaction valuations, which means more executives at companies that previously cleared the 280G computation are now subject to it.

This guide provides a practitioner-level walkthrough of the IRC 280G framework, the Reg. 1.280G-1 computational structure, the shareholder vote safe harbor mechanics, IRC 4999, gross-up clauses, and the interaction with IRC 162(m). All analysis is hedged to statute and regulation; practitioners should verify current rules at IRS.gov and consult independent tax counsel before completing any 280G calculation or advising on any transaction.

The Parachute Payment Trigger Test: The 3x Base Amount Floor

Before IRC 280G applies to any payment, the statute must be triggered. The trigger test has two components. First, the payment must be contingent on a change in ownership or control of a corporation (or on a change in the ownership of a substantial portion of its assets). Second, the aggregate present value of all payments contingent on that change, made to a particular disqualified individual, must equal or exceed 3x the individual's "base amount." See IRC 280G(b)(2)(A)(ii) and Treas. Reg. 1.280G-1 Q&A-3.

If the aggregate present value of all contingent payments is below 3x the base amount, none of the payments are parachute payments under IRC 280G. There is no partial application: the 3x floor is an all-or-nothing trigger. This means that structuring total contingent compensation to stay just below 3x the base amount is a legitimate and commonly used planning strategy, often called a "280G cutback" or "better-after-tax" analysis.

Once the 3x threshold is crossed, the "excess parachute payment" is computed differently. The excess is the amount of each parachute payment that exceeds the allocable portion of 1x the base amount -- not 3x. The 3x figure is used only as the trigger threshold. The 1x base amount acts as a floor below which no excess exists. See IRC 280G(b)(1) and Treas. Reg. 1.280G-1 Q&A-38. This distinction is computationally significant: an executive whose parachute payments slightly exceed 3x the base amount will have a relatively small excess parachute payment (the amount above 1x), but will owe a 20% excise tax on that entire excess under IRC 4999.

A payment with a present value below 1x the base amount is completely excluded from IRC 280G coverage under IRC 280G(b)(4)(A). This "de minimis" exclusion applies to any single payment, not to the aggregate. Payments below this individual-payment floor are not parachute payments regardless of how large other payments to the same individual may be.

Base Amount Computation: The 5-Year Averaging Rule

The "base amount" is the cornerstone of every IRC 280G computation. Under IRC 280G(b)(3) and Treas. Reg. 1.280G-1 Q&A-34, the base amount is the disqualified individual's average annual compensation from the corporation (or from a related entity within the controlled group) that was includible in gross income for the most recent five taxable years ending before the date of the change in ownership or control. If the individual has been employed for fewer than five years, the averaging period is the actual period of employment with the corporation.

What Counts in the Base Amount Computation

For employees, the primary source of includible compensation is Form W-2, Box 1 (wages, tips, and other compensation). This includes regular salary, bonuses, commissions, and any other compensation that was includible in gross income for the year. It excludes employer contributions to qualified plans (which are not includible in gross income for the year of contribution), employer-paid health insurance premiums excluded under IRC 106, and fringe benefits excluded under IRC 132. For shareholder-employees of S corporations, the relevant amount includes both W-2 wages and allocable S corporation income includible in gross income via Schedule K-1, but only to the extent that amount was actually includible. Verify the current scope of includible compensation under Q&A-34 through Q&A-36 of Treas. Reg. 1.280G-1 at IRS.gov before computing any base amount.

Key Base Amount Traps for Practitioners

Several edge cases affect the base amount averaging that are frequently overlooked in deal diligence. First, if an executive received a large one-time bonus in one of the five prior years, that amount inflates the base amount and may reduce or eliminate the excess parachute payment. Conversely, if one of the five years had low or zero compensation (for example, a year in which the individual was employed for only part of the year), that year's actual includible amount -- potentially a partial-year figure -- is averaged into the denominator. Q&A-35 of Treas. Reg. 1.280G-1 addresses how to handle short years. Second, compensation from related corporations within the controlled group is included in the base amount computation under Q&A-34(c), meaning the practitioner must gather compensation data from all related entities, not just the direct employer. Third, compensation that was deferred and has not yet been included in gross income is not in the base amount for the year deferred -- it enters the computation in the year of inclusion. Verify the current treatment of deferred compensation in the base amount under Treas. Reg. 1.280G-1 Q&A-34 at IRS.gov.

What Counts as a Payment in the Nature of Compensation

Under IRC 280G(b)(2)(A) and Treas. Reg. 1.280G-1 Q&A-11 through Q&A-14, a parachute payment is any payment in the nature of compensation to (or for the benefit of) a disqualified individual, if the payment is contingent on a change in ownership or control and the aggregate-present-value trigger test is met. The phrase "payment in the nature of compensation" is broad enough to encompass virtually any economic benefit transferred to an executive in connection with a transaction, including items that might not initially appear to be "compensation" in the conventional sense.

Accelerated Salary, Bonus, and Severance

The most straightforward category of parachute payments consists of cash compensation that is accelerated or paid exclusively because of a change of control: change-in-control severance payments, accelerated bonus payments (whether discretionary or formula-based), and salary continuation arrangements. These payments are contingent on the change of control by definition and are payments in the nature of compensation. Their present value is included at face value (or at discounted present value if deferred) in the aggregate computation.

Accelerated Equity Vesting

Accelerated vesting of restricted stock, restricted stock units (RSUs), stock options (both incentive stock options under IRC 422 and nonstatutory stock options), and other equity awards is one of the most commonly encountered -- and frequently undervalued -- components of a 280G computation. Under Treas. Reg. 1.280G-1 Q&A-24(b), the portion of an equity award that vests on an accelerated basis as a result of a change of control is treated as contingent on the change. The value of the acceleration is generally the present value of the vesting acceleration benefit: the value the award has at the time of the change of control, discounted back (using the applicable federal rate) by the period of acceleration. For unvested stock options, the value is generally measured using the spread (the excess of the stock's fair market value over the exercise price at the time of the change of control), multiplied by the fraction of the option that is accelerated, discounted by the acceleration period. Confirm the current valuation methodology for accelerated equity under Q&A-24 of Treas. Reg. 1.280G-1 at IRS.gov.

Non-Compete Payments and Post-Closing Consulting Agreements

Non-compete payments and post-closing consulting agreements made to disqualified individuals require careful analysis. Under Treas. Reg. 1.280G-1 Q&A-38, a portion of a payment may be excluded from the parachute payment calculation if the taxpayer can establish by "clear and convincing evidence" that the payment represents reasonable compensation for services actually rendered (or to be rendered) after the change of control, or represents reasonable consideration for an enforceable covenant not to compete. The allocation between parachute and non-parachute amounts is proportionate, and the burden of proof falls on the taxpayer. The IRS scrutinizes this allocation closely, particularly for non-competes entered into contemporaneously with a transaction, because the market rate for a non-compete executed under the duress of an acquisition closing is rarely the product of arm's-length bargaining.

COBRA Premiums, Enhanced Retirement Benefits, and Perquisites

Other payments that are sometimes overlooked in a 280G analysis include employer-paid COBRA continuation premiums for a post-termination period that commences on account of a change of control, enhanced employer contributions to nonqualified deferred compensation plans that vest upon a change of control, the value of accelerated vesting of supplemental executive retirement plan (SERP) benefits, and the value of accelerated post-retirement welfare benefits. All of these are potentially "payments in the nature of compensation" that are contingent on a change in ownership or control if the governing agreement conditions them on that event.

Change in Ownership or Control: The Three Definitional Triggers

IRC 280G(b)(2)(A)(i) defines a "parachute payment" as a payment contingent on a "change in the ownership or effective control of a corporation, or in the ownership of a substantial portion of the assets of a corporation." Treas. Reg. 1.280G-1 Q&A-27 through Q&A-29 elaborate three separate change-in-control tests. A transaction need satisfy only one of these three tests to trigger the IRC 280G analysis.

Test 1: Change in Ownership (More Than 50% of FMV or Voting Power)

A change in ownership occurs when any one person (or more than one person acting as a group) acquires ownership of stock of the corporation that, together with stock already held by that person or group, constitutes more than 50% of the total fair market value or total voting power of the stock of the corporation. See Treas. Reg. 1.280G-1 Q&A-27(b). A transaction that is clearly a majority stock acquisition -- a private equity buyout, a strategic merger in which one party holds over 50% after closing -- satisfies this test without further analysis. However, the test looks at accumulated ownership over time (it is not limited to a single transaction), so a series of incremental acquisitions by the same person or group can eventually cross the 50% threshold and trigger a retroactive 280G analysis of all change-of-control-contingent payments at that point.

Test 2: Change in Effective Control (20% Voting Power in 12 Months)

A change in effective control occurs when, during any 12-month period, any one person (or group acting in concert) acquires stock possessing 20% or more of the total voting power of all outstanding stock of the corporation, or a majority of the members of the corporation's board of directors is replaced during any 12-month period by directors whose appointment or election was not endorsed by a majority of the members of the board prior to the appointment or election. See Treas. Reg. 1.280G-1 Q&A-27(c). The 20% voting power acquisition and the board-change test are independent: either one constitutes a change in effective control. This test is particularly relevant for minority acquisitions, activist investor campaigns, and post-IPO governance restructurings where no single shareholder crosses 50% but a 20% block shifts voting dynamics significantly.

Test 3: Change in Ownership of Substantial Portion of Assets (One-Third of Total Gross Assets)

A change in the ownership of a substantial portion of the corporation's assets occurs when, during any 12-month period, any one person (or group acting in concert) acquires assets from the corporation that have a total gross fair market value equal to or greater than one-third of the total gross fair market value of all the assets of the corporation immediately prior to the acquisition. See Treas. Reg. 1.280G-1 Q&A-29. "Total gross fair market value" means the value of all assets of the corporation, including assets held by a subsidiary, without reduction for liabilities. The one-third test is measured against total gross assets, not net assets, which means an asset-light corporation whose goodwill or intellectual property constitutes a significant portion of total gross fair market value can trip this test on an IP licensing transaction or partial asset sale.

The Private Company Shareholder Vote Safe Harbor (Reg. 1.280G-1 Q&A-7)

For privately held corporations, the shareholder vote safe harbor under Treas. Reg. 1.280G-1 Q&A-7 is the single most powerful planning mechanism available under IRC 280G. If the safe harbor requirements are properly satisfied, none of the approved payments are treated as parachute payments, and neither IRC 280G (the employer deduction disallowance) nor IRC 4999 (the employee excise tax) applies to those payments. The safe harbor is entirely elective and must be actively implemented; it does not apply automatically.

Eligibility: No Publicly Traded Stock

The threshold eligibility requirement is that the corporation must have no "stock which is readily tradeable on an established securities market (or otherwise)" immediately before the change in ownership or control. See Treas. Reg. 1.280G-1 Q&A-7(b). This means the safe harbor is available to closely held C corporations and S corporations but not to any company whose equity is listed on a national securities exchange, traded over the counter on an established market, or otherwise readily tradeable. A company that completes an IPO and then undergoes a change of control cannot use the safe harbor for the post-IPO transaction, even if it was privately held immediately before the IPO.

The Vote Mechanics: 75% Approval, Excluding Disqualified Individuals

The core of the safe harbor is a shareholder vote. The payments contingent on the change of control must be approved by shareholders holding more than 75% of the voting power of all outstanding shares entitled to vote, excluding the shares held by any disqualified individual who receives (or is to receive) a payment in the nature of compensation contingent on the change. See Treas. Reg. 1.280G-1 Q&A-7(c).

The exclusion of disqualified individual shares from the voting pool is a critical and frequently overlooked computational step. Because disqualified individuals are typically founder-executives or controlling shareholders, their exclusion from the vote universe can dramatically reduce the pool of shares eligible to vote and make the 75% supermajority threshold harder (or in some ownership structures, impossible) to reach with the remaining non-disqualified shares. For example, if two co-founder executives each hold 40% of the company's voting shares, their shares are both excluded from the eligible voting pool, leaving only 20% of total shares in the voting universe. The 75% threshold then requires 75% of that 20% pool to approve, which requires the approval of all remaining shareholders holding 15% or more of total voting power. In a company whose non-disqualified shareholders hold only 20% in aggregate, obtaining 75% of that pool may still be feasible, but the math must be run in advance.

The Adequate Disclosure Requirement

A shareholder vote obtained without adequate disclosure does not qualify for the safe harbor. Under Treas. Reg. 1.280G-1 Q&A-7(e), adequate disclosure requires that the shareholders receive sufficient information about all payments contingent on the change of control to make an informed judgment about whether to approve the payments. In practice, this means preparing a disclosure document that identifies each parachute payment (or prospective parachute payment) by amount and recipient, describes the triggering conditions, and provides a summary of the tax consequences (the IRC 280G deduction disallowance and the IRC 4999 excise tax). The disclosure should be sent to all shareholders eligible to vote, not just the largest shareholders, and the voting mechanism should allow each shareholder to cast votes proportionate to their non-disqualified shares.

IRC 4999: The 20% Excise Tax on the Disqualified Individual

IRC 4999(a) imposes an excise tax equal to 20% of the amount of any "excess parachute payment" received by a disqualified individual. The excise tax is imposed on the disqualified individual -- the employee or executive who receives the payment -- not on the corporation. The excise tax is not deductible by the disqualified individual; it is an out-of-pocket cost that reduces the net economic value of the change-of-control payment. See IRC 275(a)(6) (disallowing deduction for IRC 4999 excise taxes).

The 20% excise tax applies to the excess parachute payment: the amount of each parachute payment that exceeds the individual's allocable base amount. As discussed above in the trigger test section, the excess is computed by subtracting 1x (one times) the allocable portion of the base amount from each parachute payment -- not by subtracting 3x the base amount. The excise tax is not imposed on the total parachute payment; it is imposed on the excess, which can be substantially smaller than the total payment. However, because the excise tax is computed on the excess -- and is non-deductible -- its after-tax cost to the executive can be large relative to the incremental parachute payment amount.

The corporation must withhold the IRC 4999 excise tax from payments to affected disqualified individuals under IRC 3403 and report the excise tax on Form W-2. See IRC 4999(c). In a deal context, the target company is typically responsible for the withholding on change-of-control payments made at or around closing, and practitioners must coordinate with the payroll department to ensure proper withholding calculations and reporting. Verify current withholding and reporting requirements with a qualified payroll tax specialist and at IRS.gov.

Who Is a Disqualified Individual?

A "disqualified individual" is defined in IRC 280G(c) and Treas. Reg. 1.280G-1 Q&A-15 through Q&A-21. The category includes officers of the corporation (generally defined by reference to functional authority rather than title), shareholders who own (directly or constructively under IRC 318) more than 1% of the corporation's outstanding stock (or more than 1% of the fair market value of all outstanding stock), and highly compensated individuals (those whose annualized compensation for the base period exceeds a threshold amount specified in Reg. 1.280G-1 Q&A-19). The disqualified individual category is broader than most practitioners initially assume: mid-level executives with meaningful equity stakes and senior managers with functional authority may be disqualified individuals even if they do not carry C-suite titles. Verify the current disqualified individual definition and applicable thresholds under Q&A-15 through Q&A-21 of Treas. Reg. 1.280G-1 at IRS.gov.

Gross-Up Clauses: The Circular Computation and Why They Are Disfavored

A gross-up clause is a contractual provision in an executive employment agreement or change-in-control agreement under which the employer agrees to pay the executive an additional amount sufficient to cover the IRC 4999 excise tax, so that the executive receives the same after-tax economic benefit as if the excise tax had not applied. Gross-up clauses were more common in change-in-control agreements executed before approximately 2010. They have since become increasingly disfavored and, for most publicly traded companies, are now effectively prohibited by institutional shareholder advisory policies and market practice.

The Circular Computation Problem

The fundamental computational problem with an IRC 4999 gross-up clause is that the gross-up payment is itself a parachute payment. Under Treas. Reg. 1.280G-1 Q&A-24, a gross-up payment to cover the IRC 4999 excise tax is a payment in the nature of compensation to a disqualified individual that is contingent on a change of control. As a result, the gross-up payment is included in the aggregate present value of parachute payments to the disqualified individual, which increases the total excess parachute payment, which increases the excise tax, which increases the gross-up payment required, and so on. This circularity means the true cost of the gross-up cannot be computed by simple arithmetic: it requires solving a set of simultaneous equations (or iterating to convergence) to determine the gross-up amount that, when added to the other parachute payments, exactly covers the resulting excise tax. The formula can be derived algebraically, but the computational burden is significant and the results are highly sensitive to the marginal tax rates assumed for the executive.

ISS, Glass Lewis, and Market Practice

Institutional Shareholder Services (ISS) and Glass Lewis, the two dominant proxy advisory firms for publicly traded companies, have for many years identified IRC 4999 gross-up clauses as a negative governance factor in their executive compensation voting guidelines. Companies that include gross-up provisions in change-in-control agreements risk adverse say-on-pay recommendations from ISS and Glass Lewis, which can lead to a significant vote against management at annual meetings. While the proxy advisory firms' policies are not legally binding, a materially failed say-on-pay vote carries reputational and governance consequences that most compensation committees prefer to avoid. The market consensus among publicly traded companies is that gross-up clauses are not appropriate for new executive agreements entered into after approximately 2012, and many companies have actively eliminated legacy gross-up clauses through voluntary modifications to existing agreements. Privately held companies are not subject to ISS or Glass Lewis scrutiny, but the IRS examination risk remains: the IRS scrutinizes gross-up arrangements to determine whether the gross-up payment represents reasonable compensation for services rendered.

Relationship to IRC 162(m): Two Independent Deduction Disallowances

IRC 280G and IRC 162(m) are separate and independent deduction disallowance provisions that can apply simultaneously to the same payment made to the same executive in the same M&A transaction. Understanding the distinction -- and the interaction -- is important for practitioners advising publicly traded companies on executive compensation in deal contexts.

IRC 162(m) disallows a deduction for compensation paid to a "covered employee" of a publicly traded company to the extent that employee's annual compensation from the company exceeds a statutory amount. Compensation subject to IRC 162(m)'s cap includes all forms of remuneration, including salary, bonuses, equity awards, and -- after the Tax Cuts and Jobs Act of 2017 eliminated the performance-based compensation exception -- most forms of contingent compensation. The IRC 162(m) disallowance applies regardless of whether the payment is contingent on a change of control: it is a standalone annual cap on deductible compensation for covered employees.

IRC 280G, by contrast, disallows a deduction for "excess parachute payments" regardless of whether the recipient is a covered employee under IRC 162(m) and regardless of the annual compensation level. IRC 280G applies only when the change-of-control trigger test is met, and the disallowance is limited to excess parachute payments (amounts above 1x the base amount). But when both IRC 280G and IRC 162(m) apply to the same executive in the same year, the deduction disallowances stack: the employer loses the IRC 162(m) deduction for the portion of compensation exceeding the IRC 162(m) cap, and separately loses the IRC 280G deduction for the excess parachute payment amount. There is no ordering rule or priority between the two provisions; each operates independently on its own computational basis.

For practitioners advising on publicly traded company M&A transactions, the practical consequence is that a senior executive at a public company who receives change-of-control compensation may generate simultaneous disallowances under IRC 162(m) and IRC 280G, meaning no portion of the excess parachute payment may be deductible even if it falls below the IRC 162(m) cap, and vice versa. Verify the current interaction of IRC 280G and IRC 162(m) at IRS.gov, and review our companion guide on IRC 162(m) for the post-TCJA and post-OBBBA cap mechanics.

OBBBA and the 2025-2026 M&A Surge: Why 280G Is Being Triggered More Often

The One Big Beautiful Bill Act (OBBBA), enacted in 2025, introduced several changes to the Code that have accelerated M&A deal volume in the 2025-2026 deal cycle. The most significant for 280G purposes are: the permanent restoration of 100% bonus depreciation under IRC 168(k), which makes asset acquisitions more tax-efficient for buyers and increases after-tax returns in asset-purchase structures; the expansion of IRC 338(h)(10) election mechanics for more transaction structures; and the enhancement of qualified small business stock (QSBS) benefits under IRC 1202, which has increased valuations of founder-held companies and encouraged more private company transactions. These changes have contributed to higher deal volumes and higher transaction valuations, which in turn have caused more executives -- including many at companies that previously cleared the IRC 280G computation with comfortable margin -- to cross the 3x trigger threshold.

The mechanism is straightforward: the IRC 280G base amount is computed from historical W-2 and K-1 compensation, which is generally stable over time. The parachute payments, by contrast, include accelerated equity that is valued at current fair market value, and current company valuations have risen sharply for many high-growth companies as a result of increased deal demand and more favorable tax treatment for M&A transactions. An executive who received equity grants at a valuation of $50 million two years ago and whose company is now being acquired at a $200 million valuation will have a dramatically larger accelerated equity value in the 280G computation than the historical compensation base amount would suggest -- potentially crossing the 3x threshold for the first time.

Companies undergoing their first significant M&A event since valuations increased should not assume that a prior IRC 280G analysis (or the absence of a prior 280G concern) means no analysis is needed for the current transaction. Verify updated compensation data, current equity fair market values, and current deal structure against the IRC 280G framework before closing any transaction. Consult independent tax counsel for any transaction in which executive compensation arrangements include accelerated equity vesting or change-of-control cash payments.
