280G Analysis: Disqualified Individuals, 3x Threshold, and Mitigation

A 280G analysis is the calculation that determines whether payments to executives and other key people tied to a corporate change in control will trigger the golden parachute penalties under Sections 280G and 4999 of the Internal Revenue Code. If the payments to a covered individual reach three times that person’s average annual compensation, the company loses its deduction for the excess and the recipient owes a separate 20% excise tax on top of ordinary income taxes. Running the analysis early in a merger, acquisition, or similar transaction is the single most effective way to keep surprise tax bills from reshaping deal economics for either side.

What Triggers the Analysis

The 280G framework only activates when a qualifying change in control happens. Three kinds of events count:

A change in ownership, when a person or group acquires stock representing more than 50% of the corporation’s total fair market value or total voting power.
A change in effective control, when a person or group acquires 20% or more of the voting power within a 12-month period, or a majority of the board is replaced during any 12-month period without approval from the directors already serving.
A change in asset ownership, when a person or group acquires assets with a gross fair market value equal to or more than one-third of the total gross fair market value of all the corporation’s assets.

The effective-control triggers are rebuttable presumptions and can be challenged with evidence that no actual change in control took place. The ownership and asset thresholds are bright-line tests. The date the qualifying event occurs becomes the reference point for every subsequent calculation.¹

Who Counts as a Disqualified Individual

Only “disqualified individuals” fall under the golden parachute rules. The label applies to any employee or independent contractor who, during the 12-month period before the change in control, is:

A corporate officer of the acquired company.
A shareholder owning stock with a fair market value greater than 1% of all outstanding shares.
Among the highest-paid 1% of employees, capped at the top 250, based on the year before the change in control.

The 1% shareholder test is where people most often get tripped up, because it applies constructive ownership rules under Section 318. Stock owned by a spouse, children, grandchildren, and parents is attributed to the individual. Stock held by partnerships, estates, trusts, and corporations with 50% or more common ownership is attributed proportionally.² An executive personally owning 0.3% of the stock can still qualify as disqualified if family or related entities push the total past 1%.³

Which Payments Get Counted

Once the disqualified individuals are identified, the next step is cataloging every payment to each of them that is “in the nature of compensation” and contingent on the change in control. Common items include severance packages, transaction bonuses, accelerated vesting of stock options or restricted stock, enhanced retirement benefits, and continuation of health coverage.

Two categories are excluded. First, compensation that would have been paid regardless of the change in control. If an executive was already fully vested in a bonus payable on a fixed calendar date, that payment isn’t contingent on the deal. Second, amounts representing reasonable compensation for services the executive will actually perform after the closing.

A one-year lookback presumption catches many people off guard. Any payment made under an agreement entered into or amended within the 12 months before the change in control is presumed contingent on the deal. Rebutting the presumption requires clear and convincing evidence that the agreement was not motivated by the anticipated transaction.¹

The Base Amount and the 3x Threshold

The base amount is the benchmark. It equals the disqualified individual’s average annual compensation includible in gross income over the five most recent tax years ending before the change in control date. Someone employed for fewer than five years uses the shorter period, with compensation annualized for any partial year.¹

Only compensation actually included in gross income counts. Tax-deferred contributions to a 401(k), for example, don’t count for the year deferred. Income from exercising stock options in a prior year does count for the year it hit the return. Every dollar of base amount creates three dollars of headroom under the safe harbor, so getting the number right matters.

The core test is direct. Add the present value of all contingent payments to a disqualified individual. Present values use a discount rate equal to 120% of the applicable federal rate under Section 1274(d), compounded semiannually.³ If the total is less than three times the base amount, no penalties apply and the analysis is finished. If the total equals or exceeds three times the base amount, every dollar above one times the base amount becomes an “excess parachute payment.”¹

A Worked Example

An executive has a base amount of $500,000. Her change-in-control payments, including a transaction bonus, accelerated equity, and severance, total $1,600,000 in present value. Three times her base amount is $1,500,000. Because $1,600,000 crosses that threshold, the safe harbor is blown. The excess parachute payment is $1,600,000 minus the $500,000 base amount, or $1,100,000. The company loses its deduction for the full $1,100,000, and the executive owes a 20% excise tax of $220,000 on top of her regular income taxes.

The Cliff Effect

Notice the structure. The threshold is three times the base amount, but the excess is measured from one times the base amount. That two-times-base-amount gap means the penalties hit hard the moment the line is crossed. An executive sitting at $1,499,999 in payments owes nothing extra. At $1,500,000, the excess parachute payment jumps to $1,000,000 and the excise tax bill is $200,000. This cliff is why mitigation planning matters so much.

The Tax Consequences

Crossing the 3x threshold triggers two separate penalties that compound the damage:

The company cannot deduct the excess parachute payment. At a 21% corporate rate, losing the deduction on a $1,100,000 excess costs the company $231,000 in additional federal tax.
The recipient pays a 20% excise tax on the excess parachute payment, on top of regular federal and state income taxes. This tax is not deductible by the executive.

The excise tax is imposed under Section 4999, and employers must withhold it just like income tax when the excess parachute payments constitute wages.⁴ Combined effective rates on excess parachute payments can easily exceed 60% once federal income tax, state income tax, and the 20% excise tax are stacked together.

Valuing Accelerated Equity Awards

Accelerated vesting of stock options, restricted stock, and similar equity awards is one of the trickiest inputs. When vesting accelerates because of the change in control, the regulations treat part of the value as contingent on the transaction even if the award was granted years earlier.

The contingent portion has two components. The first is any increase in the value of the payment that results directly from the acceleration. The second reflects the lapse of the executive’s obligation to keep working, calculated at 1% of the accelerated payment multiplied by the number of full months between the acceleration date and the date the award would have vested on its original schedule.³

If an executive holds restricted stock worth $300,000 that would have vested in 24 months but accelerates at closing, the contingent amount attributable to the lapse of service is 1% × $300,000 × 24, or $72,000. That $72,000 joins the pile of contingent payments for the 3x test. The 1%-per-month formula may sound modest, but for large grants with years of remaining vesting, it adds up quickly and can be the factor that pushes someone over the safe harbor.

Mitigation Strategies

Once preliminary calculations suggest a disqualified individual will exceed the 3x threshold, several strategies can reduce or eliminate the tax penalties. The right approach depends on whether the company is private or public and on the deal structure.

Shareholder Approval (Private Companies Only)

Private companies have access to the most powerful tool: a vote of shareholders to approve the payments. If shareholders owning more than 75% of the outstanding voting stock approve, the payments are completely exempt from the golden parachute rules. Shares owned by the disqualified individuals receiving the payments are excluded from both the numerator and denominator of the vote.³

The catch is disclosure. Before the vote, the company must provide voting shareholders with adequate disclosure of every material fact concerning the payments that would otherwise be parachute payments. Incomplete or misleading disclosure invalidates the entire vote. The disclosure document typically identifies each disqualified individual, describes every contingent payment, and states the aggregate dollar value at stake.

Reasonable Compensation for Post-Closing Services

Any portion of a payment that represents reasonable compensation for services performed after the closing can be excluded from the parachute calculation. The burden is steep: reasonableness must be established by clear and convincing evidence, considering the nature of the services, the executive’s historical pay, and what comparable executives earn outside a change-in-control situation.³

If the executive’s duties after the deal are substantially the same as before, annual compensation that is not significantly greater than pre-deal pay generally qualifies. Covenants not to compete can also count as reasonable compensation for “refraining from performing services,” but only if the restriction meaningfully constrains the executive and is reasonably likely to be enforced. Paper restrictions no one intends to enforce won’t survive scrutiny.

Cutback Provisions

A cutback provision in the executive’s employment or change-in-control agreement automatically reduces payments to a level that avoids triggering the 3x threshold. The simplest version, sometimes called a hard cutback, caps payments at one dollar less than three times the base amount. No penalties apply because the threshold is never crossed.

A more executive-friendly variation is the “best-net” or “better-of” cutback. The company calculates two scenarios: what the executive keeps after taxes if payments are cut back to the safe harbor, and what the executive keeps after paying the 20% excise tax and all income taxes on the full, unreduced amount. Whichever scenario leaves the executive with more money after taxes applies. Because of the cliff effect, a range of payment amounts just above the 3x threshold leaves the executive better off with a cutback than with the full payment plus the excise tax.

Gross-Up Provisions

A gross-up takes the opposite approach: the company pays the executive an additional amount sufficient to cover the 20% excise tax, plus the income tax on the gross-up itself. This makes the executive whole but is extraordinarily expensive because the gross-up payment is itself compensation subject to the excise tax, creating a compounding effect. Full gross-ups have become increasingly rare in executive agreements due to shareholder pressure and proxy advisor scrutiny. Most companies have moved toward best-net cutbacks or no 280G protection at all.

Increasing the Base Amount

Because the base amount averages five prior years of includible compensation, actions taken before a deal closes can raise the average. Exercising vested stock options, accelerating bonus payments into the current tax year, or similar timing decisions can lift the base amount and widen the safe harbor. This works only if there is enough time before the change-in-control date for the additional income to appear on the individual’s tax return for a base-period year.

The Small Business Corporation Exemption

Payments made with respect to a corporation that qualifies as a “small business corporation” immediately before the change in control are completely exempt from the golden parachute rules. The definition borrows from Section 1361(b), the eligibility criteria for S-corporation status: a domestic corporation with no more than 100 shareholders, one class of stock, and only eligible shareholders (individuals, certain trusts, and estates). The corporation does not actually need to have elected S-corporation status. Any corporation meeting those structural requirements qualifies regardless of its tax election.³

Members of an affiliated group are not treated as a single corporation for this exemption. Each entity is evaluated on its own, which matters in acquisitions involving corporate subsidiaries.

When to Start the Analysis

A 280G analysis should begin as early as possible in a deal, ideally during due diligence and well before signing. Buyers routinely request preliminary calculations as part of their diligence, and sellers need them to evaluate how deal terms affect their executives. Early timing matters for two reasons. Mitigation strategies like a shareholder approval vote or restructured compensation arrangements need lead time; a vote crammed into the days before closing is harder to execute cleanly and more likely to invite disclosure challenges. And base-amount-increasing strategies only work if additional compensation hits the individual’s return for a year inside the five-year base period, which may require action months before closing.

Companies typically engage a compensation consulting or accounting firm to model 280G exposure for each disqualified individual, run sensitivity analyses under different deal structures, and prepare the supporting documentation for any shareholder vote or executive agreement change.
