Section 280G Golden Parachute Calculator

IRC Section 280G & 4999 Executive Tax & Cutback Optimizer (2026 Guidelines)

Determine if change-in-control parachute payments trigger federal excise taxes, estimate lost corporate deductions, and conduct an automated "Best of Net" cutback analysis to maximize after-tax executive payout.

1. Base Amount Compensation History

The Base Amount is calculated using average annual W-2 compensation (Box 1) for the years preceding the transaction.

Calculated Base Amount:$244,000

2. Proposed Parachute Payments (Change-in-Control)

Enter any payments contingent upon the change-in-control. This includes severance, accelerated equity, benefits, and special bonuses.

Total Proposed Payments:$1,150,000

3. Individual & Corporate Marginal Tax Rates

Understanding Golden Parachutes, Section 280G, and the "Best of Net" Cutback

During mergers, acquisitions, or corporate change-in-control transactions, executive compensation plans often include protective severance clauses, retention bonuses, and accelerated vesting of unvested stock options or restricted stock. Collectively, these payments and benefits are termed "parachute payments."

The Statutory Mechanics of Section 280G

To restrict excessive executive compensation, the Internal Revenue Service imposes dual tax penalties under Internal Revenue Code (IRC) Section 280G and Section 4999. The rule targets any individual who is an officer, shareholder, or highly compensated employee of the target corporation (known as a "disqualified individual") and whose change-in-control-contingent payout meets specific thresholds.

The critical threshold is 3.0 times the individual’s Base Amount. The Base Amount is the average annual taxable compensation (W-2 Box 1) for the five calendar years preceding the year of the change-in-control. If the executive has been employed for fewer than five full years, the Base Amount is averaged over their actual employment duration.

The Cruel "Cliff Effect" and Excess Parachutes

The major pitfall of 280G is its "cliff" structure:

  • If total change-in-control payments are even $1 below 3.0 times the Base Amount, no 280G penalties apply.
  • If total payments are equal to or exceed 3.0 times the Base Amount, 280G is triggered. But crucially, the excise tax penalty is calculated on everything exceeding 1.0 times the Base Amount, not the 3.0 times threshold.

For example, if an executive has a Base Amount of $250,000, their Safe Harbor Threshold (3.0x) is $750,000.

  • A proposed payout of $749,000 is perfectly safe: the executive pays regular taxes, and the corporation deducts the full amount.
  • A proposed payout of $751,000 triggers Section 280G. The "excess" is measured as everything over 1.0x Base ($250,000). Thus, the taxable Excess Parachute is $501,000.
  • The executive owes a 20% excise tax on $501,000 (amounting to $100,200), and the corporation loses a tax deduction of $501,000 (adding $105,210 to the transaction tax cost at a 21% corporate tax rate).

The "Best of Net" Cutback Analysis

To prevent this cliff from erasing the executive's incremental payout, executive employment agreements frequently include a "Best of Net" or "Net-Best" cutback provision. This provision dictates that if Section 280G is triggered, the executive's payout will be cut back to 2.999 times their Base Amount (the safe harbor limit) ONLY IF doing so results in a higher after-tax take-home amount than receiving the full, uncapped payment.

As a general heuristic:

  • When proposed payments are only slightly above the 3x threshold: Capping the payments almost always yields a superior take-home return, because the 20% excise tax is calculated from the 1.0x Base cliff and easily exceeds the extra compensation.
  • When proposed payments are significantly above the 3x threshold: The absolute volume of the payout compensates for the tax penalty. In these cases, taking the full payment and paying the 20% excise tax will result in more cash in hand for the executive, although the corporation still loses its tax deduction.

Mitigation Strategies: The Private Company Shareholder Approval

For private corporations, Section 280G offers an invaluable escape hatch. Under IRC Section 280G(b)(5), a private company can completely avoid 280G penalties if:

  • The payments are approved by a separate vote of shareholders holding at least 75% of the voting power of all outstanding stock immediately before the transaction.
  • There has been full disclosure of all material facts concerning all parachute payments to all shareholders.

This vote must be a separate vote (not part of the general merger approval vote), and the executive must agree to forfeit the payments if the 75% shareholder approval is not obtained. This shareholder approval exception is not available for public companies.
