Section 280G of the Internal Revenue Code — commonly called the golden parachute rules — imposes significant adverse tax consequences on both employers and employees when a change in control triggers the payment of compensation that exceeds defined thresholds. Understanding how Section 280G works, who it applies to, and what strategies are available to manage its impact is essential in any M&A transaction that involves executive compensation, accelerated equity vesting, or severance arrangements tied to a change of control.

What Section 280G Prohibits and Penalizes

Section 280G does not actually prohibit the payment of change of control compensation. Instead, it penalizes such payments when they exceed certain thresholds. Specifically, Section 280G disallows the employer’s deduction for the excess portion of a “parachute payment” that constitutes an “excess parachute payment.” Section 4999 imposes a 20 percent excise tax on the recipient (the employee or executive) on the same excess amount. The result is that the employee pays income tax plus the 20 percent excise tax on the excess payment, and the employer loses its deduction. This double penalty makes large change of control compensation packages very expensive from a tax perspective.

A parachute payment is a payment contingent on a change of ownership or control of a corporation that is made to a disqualified individual. Disqualified individuals include officers (the company’s top officers by compensation), shareholders who own more than 1 percent of the company’s stock, and highly compensated individuals. The change of control trigger covers acquisitions, mergers, and other transactions in which one person or group acquires more than 50 percent of the total fair market value or voting power of the company’s stock, or a substantial portion of its assets.

How Parachute Payments Are Calculated

The determination of whether a payment constitutes an excess parachute payment requires a comparison between the present value of the total change of control payments made to the individual and the individual’s base amount. The base amount is generally the individual’s average annual W-2 compensation from the company for the five years preceding the year in which the change of control occurs (or the entire period of employment, if shorter).

A payment becomes a parachute payment when the present value of all change of control payments equals or exceeds three times the base amount. An excess parachute payment is the amount by which total parachute payments exceed one times the base amount. For example, if an executive’s average annual compensation is $1 million, the three-times threshold is $3 million. If the executive receives $3.5 million in change of control payments, the entire amount qualifies as a parachute payment, and the excess parachute payment is $2.5 million (the total payment of $3.5 million less the one-times base amount of $1 million). The 20 percent excise tax applies to the $2.5 million excess.

Payments that are counted as parachute payments include cash severance payments, accelerated vesting of stock options and restricted stock, retention bonuses, transaction bonuses, fringe benefits, and any other compensation that is contingent on the change of control. Non-compete payments and consulting arrangements that are contingent on the change of control are also counted. For equity awards, the parachute payment amount is the spread value at the time of acceleration plus any additional amount attributable to the lapse of restrictions, which can be very large for long-tenured executives with significant equity holdings.

The Private Company Shareholder Approval Safe Harbor

For public companies, there is no effective mechanism to avoid the Section 280G excise tax other than reducing the compensation amounts. However, private companies (defined as companies whose stock is not readily tradeable on an established securities market) have access to a valuable safe harbor: the Section 280G consequences can be entirely avoided if the payment is approved by shareholders holding more than 75 percent of the outstanding voting stock of the company, after adequate disclosure of the nature and amount of the payments.

The private company shareholder approval safe harbor is one of the most important planning tools in M&A compensation structuring. If a 280G analysis identifies that proposed change of control compensation will result in excess parachute payments, the seller can conduct a shareholder vote to ratify the payments before closing. If the vote achieves the required 75 percent threshold, the parachute payment rules do not apply, and neither the 20 percent excise tax nor the employer’s deduction disallowance is triggered.

Conducting the shareholder vote requires careful preparation. The company must provide each shareholder with a disclosure that adequately describes the payments being approved, including the nature, amount, and terms of each component. The disclosure must identify each disqualified individual by name. The vote must be conducted before the change of control occurs. If any shareholders cannot or will not vote — for example, because their shares are subject to transfer restrictions or because they are not reachable before closing — those shares are counted as not having voted in favor, which can make the 75 percent threshold harder to achieve.

The 280G Gross-Up Debate

In the early years of Section 280G, it was common for executive employment agreements to include gross-up provisions that obligated the company (or the buyer) to make an additional payment to the executive to compensate for the 20 percent excise tax imposed under Section 4999. The rationale was that the executive had negotiated for a specific level of after-tax compensation, and the excise tax should not reduce what the executive received. However, gross-up provisions are now strongly disfavored by institutional shareholders, governance advisors, and increasingly by private equity sponsors, because they amplify the parachute payment problem by adding more compensation that itself can trigger additional excise tax, creating an exponential gross-up obligation.

Most modern executive employment agreements and M&A deal documents use one of two alternatives to the gross-up: either a best-net cutback provision (which automatically reduces the change of control payments to the level just below the three-times threshold, so that no parachute payments are triggered and the executive receives slightly less but faces no excise tax), or no cutback at all (where the executive receives the full payment but is responsible for paying the excise tax out of pocket). The best-net cutback approach is generally preferred when the amount of the potential cutback is modest relative to the total payment; the no-cutback approach is appropriate when the executive is willing and able to bear the excise tax cost.

Pre-Closing Planning Strategies

The most effective strategy for managing Section 280G exposure is to conduct a detailed 280G analysis as early as possible in the deal process — ideally before the letter of intent is signed — so that there is time to restructure compensation arrangements to reduce or eliminate the problem. Common restructuring strategies include: reallocating compensation between change of control-contingent and non-contingent payments (non-contingent payments do not count toward the parachute payment threshold), accelerating compensation out of the change of control context so it is paid before the relevant change of control period, implementing the private company shareholder approval safe harbor, and redesigning equity awards to reduce the vesting acceleration amounts.

280G analysis and planning requires the coordinated involvement of tax counsel, compensation advisors, and M&A counsel. It should be started early enough to allow time for plan amendments, compensation agreement revisions, and shareholder vote mechanics to be implemented before the transaction closes. Companies that have not conducted a 280G analysis before their sale process is underway may find that the excise tax exposure is significant and that the available remediation options are limited by the time pressure of the deal timeline.
