Section 280G – the golden parachute tax rule – is a hidden trap that can reduce founder payouts in a startup acquisition. For venture‑backed startup founders and executives, understanding the 280G trap is essential to protecting exit proceeds.

Section 280G applies when change‑in‑control compensation (cash bonuses, severance, and equity acceleration) for founders and executives exceeds a specific amount, triggering a 20% excise tax on “excess parachute payments” and denying the company a tax deduction on that same compensation.

Many founders only hear about Section 280G when it’s almost too late, usually when an acquisition is on the table, and the deal team is deep into diligence. That’s exactly why it feels like a trap: The rule only shows up when your startup is winning, and then threatens to claw back a meaningful piece of the upside.

What Section 280G Actually Does

The 280G trap happens when parachute payments to executives slightly exceed a strict IRS threshold, and suddenly become heavily penalized.

Under Section 280G, a parachute payment is broadly defined as compensation that is contingent on a change in control of the corporation and paid to a “disqualified individual” (certain officers, highly compensated employees, and significant shareholders). That almost always includes founders.

A change in control generally means a significant shift in who owns or controls a company, usually when a person or group acquires more than 50% of the voting power or equity, or when the company is merged, sold, or transfers substantially all of its assets to another entity. In the context of startup exits and 280G, it’s the transaction (stock sale, merger, or asset sale) that hands effective control of the company to a new owner and therefore triggers any compensation that’s contingent on that event.

When those contingent change‑in‑control payments reach or exceed three times a disqualified individual’s average W-2 compensation over five years (the “base amount”), they can trigger the 280G excise tax and loss of deduction.

Under Section 280G:

  • The IRS evaluates “parachute payments” tied to an acquisition or change in control.
  • These payments are compared to an executive’s base amount.
  • If total payments exceed 3 times the base amount, penalties apply.

The most founder‑unfriendly feature of 280G is its “cliff.” It’s not a gradual phase‑in – it’s a hard line. Crossing the threshold by even one dollar triggers:

  • A 20% excise tax on the executive.
  • Loss of the company’s tax deduction on the excess compensation.

That means less cash to the founder and worse deal economics for the buyer.

Why the Cliff Is So Dangerous

The structure of 280G creates a disproportionately serious outcome. A minimal overage can create a massive tax impact.

Let’s look at an example of an executive:

  • Base executive average salary over 5 years: $300,000
  • Threshold: 3 x $300,000 = $900,000
  • Unvested equity: $500,000
  • Change of control bonus: $300,000
  • Consulting agreement for services after closing: $100,001
  • Total parachute payments: $900,001

That single extra dollar triggers the rule.

Now the “excess parachute” becomes:
$900,001−$300,000 = $600,001

What happens as a consequence?

  • The executive pays 20% tax on $600,001, totalling $120,000.20.
  • The company loses the deduction on $600,001.

This is the essence of the 280G trap: A small oversight leads to a six-figure tax hit. And this example only covers the federal excise tax. The executive will also owe ordinary income tax, plus state, local, and Medicare taxes on certain amounts, which pushes the effective tax rate even higher.

In this situation, there’s an easy fix. Simply reduce the consulting agreement, or the change-of-control bonus. But what happens if the “disqualified individual” has significant unvested equity in the company, like a founder? Let’s look at another example:

  • Founder/CEO average salary over 5 years: $165,000 (from our Startup CEO Salary Report)
  • Threshold: 3 x $165,000 = $495,000
  • Unvested equity: $8,000,000
  • Change of control bonus: $500,000
  • Total parachute payments: $8,500,000

Now our founder’s “excess parachute” is:

8,500,000 - $495,000 = $8,005,000

And the result is:

  • The founder pays 20% tax on $8,005,000, totalling $1,601,000, plus ordinary income tax, state, local, and Medicare taxes on certain amounts.
  • The company loses the deduction on $8,005,000.

That’s a big tax bill!

What Counts as a Parachute Payment?

Many founders underestimate how much compensation gets swept into 280G calculations. Generally speaking, if the payment is contingent on a change of control, it counts as a parachute payment. From a startup accounting perspective, the following commonly qualify:

  • Accelerated vesting of stock options or restricted stock units (RSUs). This is how most founders fall into the 280G trap. When unvested stock options or RSUs accelerate because of a sale or merger, they become parachute payments.
    • There’s one qualification that can reduce the tax burden: If the payment was virtually certain to be made anyway, special rules apply. The value of the payment is set at the net present value (NPV) minus the present value of the payment on the date it would have naturally vested. Also, an amount of 1% of the full accelerated payment multiplied by the number of full months of acceleration is added.
  • Change-of-control bonuses. This includes ** ** any bonus that’s promised to become payable or paid upon a change of control.
  • Retention bonuses. Any bonuses paid to employees and founders to make sure they stay with the company through closing, contingent on the change of control occurring.
  • Salary continuation. Any commitment that allows the employee to continue to receive salary for any period after the closing.
  • Non-compete payments. Any payment for not competing with the company if the payment is contingent on the change of control.
  • Non-solicitation payments. Any fees paid as part of an agreement for not soliciting customers or employees after the acquisition.
  • Consulting agreements. Any agreement to provide consulting services after the change in control, if the engagement is contingent upon the acquisition closing.

Because these elements are often defined years earlier in employment agreements and equity plans, the trap is usually set long before the exit. And without strong startup accounting and close coordination with legal and tax advisors, it’s easy to underestimate how much parachute compensation is actually baked into your cap table and comp plans.

How Startups Accidentally Fall Into the 280G Trap

In practice, the trap usually emerges in one of a few patterns:

  • Founders with low historical cash comp but large equity stakes see big option acceleration and a deal bonus push them over the 3X threshold.
  • Companies add large change‑in‑control severance or retention packages late in the life of the startup without modeling 280G, inadvertently creating excess parachute payments.
  • Inadequate records and incomplete modeling lead teams to misjudge whether they’re above or below the line until diligence forces a re‑calculation.

These surprises are particularly painful because they show up after expectations have been set.

Strategies Startups Can Use to Manage the 280G Trap

There’s no one‑size answer, because every deal and cap table is different. But common strategies, implemented with tax and legal counsel, include:

  • Adjusting bonus amounts or timing so key individuals stay under the 3X safe harbor where that makes economic sense.
  • Re‑designing vesting and acceleration mechanics, like shifting from full single‑trigger acceleration to more nuanced double‑trigger structures. Single‑trigger acceleration (everything vesting at closing) can dramatically increase parachute payments because all remaining equity is treated as deal‑contingent compensation. Double‑trigger acceleration – where vesting requires both a change in control and a qualifying termination – often reduces 280G exposure while still protecting founders if they are let go after the acquisition.
  • Using cutback or gross‑up provisions, depending on the negotiating leverage and tax priorities of the parties. A cutback provision automatically reduces parachute payments to stay just below the 3X threshold, trading a slightly smaller headline payout for avoiding the excise tax and deduction disallowance. A gross‑up provision does the opposite: The buyer agrees to cover some or all of the excise tax, increasing the total cost of the package but preserving the founder’s intended net payout when the parties decide the tax hit is worth absorbing.
  • Obtaining disinterested shareholder approval in certain private company situations, which can “cleanse” some parachute payments and avoid excess treatment when structured properly (more on this below).

The critical point is timing. These decisions should be made before terms are fully baked into the deal – ideally well before any letter of intent (LOI).

Managing 280G Using Shareholder Approval

Founders sometimes hear that they can “fix” 280G with shareholder approval, but the mechanism is highly technical. In certain cases, however, it can turn otherwise penalized parachute payments into non‑penalized compensation if it’s used correctly.

For non‑public companies (no readily tradeable stock), Section 280G offers a special exception often called a “280G cleansing vote.” If you meet the requirements, the excess parachute payments are not treated as excess under 280G, so:

  • The 20% excise tax is eliminated.
  • The company (or buyer) keeps its tax deduction for the payments.

The core elements are:

  • The company is privately held (stock not readily tradeable).
  • Disinterested shareholders – those not receiving parachute payments and not constructively treated as disqualified individuals – owning more than 75% of the voting power approve the payments.
  • All voting shareholders receive adequate disclosure of all material facts about the parachute payments and 280G implications.
  • Each affected founder/executive signs a binding waiver of their right to the excess parachute payments if shareholder approval is not obtained (the right is restored only if the vote passes).

In practice, the process looks like this:

  1. Tax and legal advisors perform a detailed 280G analysis, including base amounts, parachute payments, present value, and potential excess.
  2. Founders and other disqualified individuals agree in writing to waive any excess parachute amounts if shareholders don’t approve.
  3. The company prepares a disclosure package describing the transaction, the change‑in‑control payments, the excess parachute exposure, and the consequences.
  4. Disinterested shareholders – excluding anyone receiving parachute payments – are asked to vote specifically on approval of the excess parachute payments.
  5. If more than 75% of the disinterested voting power approves, the waived payments are restored and treated as non‑excess, avoiding the excise tax and deduction disallowance.

Because this exception is not available to public companies and has strict procedural rules, it’s a planning tool for private, venture‑backed startups that want to address 280G before closing.

Why This Matters Before an Exit

280G is often treated as a last-mile tax issue, but it is actually a problem rooted in early decisions. The strategies outlined above work best if you understand the mechanics of Section 280G and start planning early. Here’s a timeline founders can use to address 280G.

Years before exit (ongoing)

  • Set a reasonable salary using market data. Use Kruze’s Startup CEO Salary Report and Startup Compensation Guide benchmarks to keep founder/CEO pay within a rational range for your stage, instead of underpaying yourself.
  • Design comp plans with 280G in mind. Avoid casually adding rich single‑trigger acceleration or outsized change‑in‑control severance without modeling parachute payments. Coordinate with your tax and legal advisors when updating offer letters, equity plans, and retention packages.
  • Keep your finances and cap table updated and accurate. Accurate W‑2 histories, option grants, vesting schedules, and ownership records are essential for any future 280G analysis.

6-12 months before a likely exit (or as soon as you see a path to sale)

  • Calculate your base amount. For each founder/executive who might be a disqualified individual, compute the five‑year average W‑2 compensation. This is the base amount in the 280G formula.
  • Model parachute payments. Estimate transaction bonuses, severance, and the present value of accelerated equity and other deal‑contingent compensation.
  • Run the 3X test. Determine whether projected parachute payments are likely to reach or exceed three times each person’s base amount, and quantify any excess.
  • Explore planning options early. If you’re on track to trigger 280G, talk to your advisors about:
    • Adjusting bonus amounts or timing.
    • Tweaking vesting and acceleration mechanics.
    • Allocating some payments to well‑documented noncompete or consulting arrangements.
    • Whether a disinterested shareholder approval vote is available given your cap table and investor base.

This is the window where you still have meaningful flexibility.

During acquisition negotiations (LOI through signing/closing)

  • Flag 280G early with the buyer. Make sure the acquirer’s deal team understands the potential excise tax and deduction loss. 280G is their problem too, so they usually care about getting it right.
  • Decide whether to pursue a 280G vote. If your company qualifies as private and your ownership structure supports it, work with your legal counsel to:
    • Identify disinterested shareholders and confirm you can reach the 75% voting‑power threshold.
    • Obtain waivers from founders/executives.
    • Prepare the disclosure materials and coordinate the vote timing before closing.
  • Negotiate alternative protections if a vote isn’t feasible. Consider cutback provisions (reducing payments to stay under 3X) or gross‑ups (buyer covering some of the excise tax), as well as deal structuring that minimizes contingent parachute treatment.
  • Document it clearly. Ensure your proxy/consent materials and transaction documents describe the parachute payments, the 280G analysis, and who bears the risk if a vote fails or the IRS disagrees.

Plan for the 280G Trap Before It Costs You

The best time to address 280G is long before an acquisition is imminent. Kruze Consulting works with founders, finance leaders, and boards to keep books accurate, equity records organized, and compensation data ready for detailed 280G analysis. That means fewer surprises during diligence, better coordination with legal and tax advisors, and more confidence when a change in control is on the table.

Section 280G and the 280G Trap

In simple terms, what is Section 280G?

Section 280G is a tax rule that penalizes certain “golden parachute” payments – deal‑contingent bonuses, severance, and equity acceleration – when they reach or exceed three times an executive’s five‑year average W‑2 compensation.

Why is 280G considered a trap for founders?

Because it uses a cliff test and a low historical salary can make it very easy to exceed the threshold, turning a seemingly normal exit package into an excess parachute subject to a 20% excise tax and lost deductions.

Are all change‑in‑control payments parachute payments?

No, but many are. Parachute payments are compensation “in the nature of” pay that is contingent on the change in control and made to certain disqualified individuals, including founders, executives, and major shareholders.

How does startup accounting help with 280G?

Accurate startup accounting provides accurate salary history, equity data, and transaction‑related compensation information, which advisors need to calculate the base amount, model parachute payments, and design strategies to reduce or manage excess parachute exposure.

What should founders do now to reduce 280G risk?

Use market data (like Kruze’s CEO Salary Report) to avoid setting low salaries, review change‑in‑control and acceleration terms with counsel, and make sure your books, payroll, and cap table are up-to-date and accurate so advisors can run credible exit and 280G scenarios before you’re in live deal mode.
