Screen the transaction before promising the bonus

Certain compensation contingent on a corporate change of control can trigger section 280G deduction denial and a separate section 4999 excise tax. The analysis starts with the corporation, the transaction, the recipient, and available exceptions. It does not start by applying twenty percent to every founder bonus. Corporations that satisfy the statutory small-business exception and qualifying private-company shareholder approval arrangements require their own eligibility and procedural review.

For a seller, the immediate decision is whether the compensation terms can be signed before this analysis is complete. Put the bonus, severance, vesting acceleration, benefits, and any promised tax gross-up into one schedule. Several individually modest arrangements can become material when combined. Have the transaction team identify which arrangements depend on closing and which would have been paid anyway. The schedule should follow the contractual trigger rather than the account in which the company recorded the expense.

Compare the threshold with the excess payment

Assume a hypothetical executive has a properly computed $200,000 base amount. The three-times threshold is $600,000. A simplified $590,000 package is below that threshold, while a $610,000 package crosses it. If the whole latter amount is a parachute payment and no reduction or exception applies, the excess is $410,000 after subtracting the base amount, rather than merely the $10,000 above the threshold. A twenty-percent excise tax on that excess is $82,000.

This cliff makes a last-minute $20,000 increase economically different from an ordinary bonus increase. The example omits present-value calculations, multiple payment allocation, reasonable-compensation adjustments, and the possible exception procedures. Use it to recognize the decision point, then replace its assumptions with the recipient's actual history and agreements. Also show the corporation's lost deduction separately from the executive's excise tax; the costs fall on different parties and can affect negotiated sale economics differently.

Build the five-year compensation evidence

Request the compensation history used to establish the base amount, including payroll records, equity compensation events, and relevant tax reporting. Reconcile the history to the individual actually receiving the payment. A spreadsheet labeled founder salary may omit taxable option exercises or compensation paid by another relevant group company. Identify periods shorter than the standard history and obtain a written computation explaining the treatment rather than filling missing years with zeros.

Collect option plans, employment agreements, side letters, board approvals, retention arrangements, and proposed amendments. Ask the compensation specialist to value accelerated vesting and distinguish payment timing from the value of acceleration. Keep a version of the calculation corresponding to each material contract draft. A result based on an early purchase agreement may become obsolete when the final employment package adds guarantees, extends severance, or changes the vesting conditions immediately before closing.

Decide who bears the cost before signing

Compare a contractual cutback, an unmodified package, and any tax gross-up using the same sale assumptions. A gross-up can increase compensation and require a more involved calculation; simply adding $82,000 to the example is not a complete gross-up model. Record whether the purchase agreement treats these amounts as seller expenses, company liabilities, or buyer-funded compensation. Otherwise the founder can see both an unexpected personal tax and an unexpected reduction in equity proceeds.

Where an approval exception may be available, resolve the voting population, disclosure, waiver, and timing requirements before the vote is scheduled. An informal board acknowledgment is not a substitute for the required shareholder process. Keep the responsible legal and compensation professionals attached to this workstream through closing. Changes to the buyer's structure or the identity of the employing company should return to them for review even when the headline purchase price stays constant.

Reconcile the final agreements to payment reporting

Before funds move, compare the executed documents with the approved calculation and payroll instructions. Give payroll a recipient-level payment and withholding schedule that separates ordinary wage withholding from any applicable excise-tax reporting. Preserve the threshold calculation, exception analysis, valuation support, and approval evidence in the permanent sale file. After closing, reconcile the actual payments and vesting events to the model. A useful completion record shows what changed, who approved the final treatment, and how the owner proceeds forecast absorbed each company-level and individual-level cost.
