Retention bonus clause: sample wording and repayment rules

A retention bonus clause promises an employee a payment for staying with the employer until a set date or milestone, such as the end of a project or a sale of the business, and says what happens if the employee leaves early, is laid off, or the date is never reached.

A retention bonus, sometimes called a stay bonus, pays an employee for staying through a critical period. The clause has to answer one question above all: what happens if employment ends before the date. Resignation usually forfeits it, layoff usually pays it, and paying upfront with repayment raises state wage law issues.

Sample clause

Written for retention letter from Canyon Health IT, a fictional Phoenix software firm, to a lead engineer during a hospital system go live.

Retention Bonus. (a) Amount. The Company will pay the Employee a retention bonus of $15,000, less required withholdings, in two parts: $5,000 on the first payroll after 31 March 2027 and $10,000 on the first payroll after the Go Live Date, if the Employee is employed on each date. (b) Leaving early. If the Employee resigns, or is terminated for Cause, before a payment date, any unpaid part is forfeited. Parts already paid are not repayable. (c) Termination without Cause, death or disability. If employment ends for any of these reasons before a payment date, the Company pays any unpaid part within 30 days, subject in the case of termination without Cause to a signed release. (d) Delay. If the Go Live Date has not occurred by 30 September 2027, the second part is paid on the first payroll after that date if the Employee is still employed.

Sample wording, not legal advice.

Variants

Lump sum at the date

A simple stay bonus for a defined period, such as staying until a business sale completes.

If the Employee remains employed through the Closing Date, the Company will pay a retention bonus of $20,000 within 30 days after the Closing Date.

Paid upfront with repayment

An employer that wants to pay now to secure commitment, with repayment if the employee leaves before the date.

The Company pays the retention bonus of $15,000 on signing. If the Employee resigns before 31 December 2027, the Employee repays a pro rata share for each full month not worked, within 30 days after leaving, to the extent permitted by law.

Split by milestone

A long project where staying through each phase matters, with a payment tied to each one.

One third of the retention bonus is paid on completion of each of the design, build and go live phases, if the Employee is employed on the completion date of that phase.

What to negotiate

The risk of leaving it out

A retention bonus promised in a meeting or an email without written terms leads to disputes when someone leaves just before the date, is laid off, or the project slips. The employer may end up paying people who left, or the employee may lose a bonus they reasonably thought they had earned, and both sides argue from vague words.

Leaver cases against payment

Resignation before the date: unpaid parts forfeited. Termination for cause: forfeited. Termination without cause, death or disability: unpaid parts paid within 30 days, with a release for termination without cause. Still employed on the date: paid. This table is the core of a retention clause, and writing it out avoids most disputes. Parts already paid are not clawed back in the sample, which keeps it clear of repayment questions.

Tax treatment

A retention bonus is taxable wages. For federal income tax withholding, IRS Publication 15 treats bonuses as supplemental wages, and an employer paying one separately from regular wages may withhold at the flat supplemental rate of 22 per cent, or 37 per cent on supplemental wages above $1 million in a year. The rate of withholding does not change the tax actually owed, which is settled on the employee's return. Law checked on 21 October 2026. This page explains how the law works and is not legal advice.

Final pay rules

When employment ends, state laws set when final wages must be paid, and the US Department of Labor notes that there is no federal requirement to pay final wages immediately. Whether an earned retention bonus counts as wages due at termination depends on the state and the clause's wording, so stating the payment timing for each leaver case, as the sample does, matters.

Questions people ask

Do I get my retention bonus if I am laid off?

It depends on the clause. Many retention clauses pay the bonus, or the unpaid part, if the employee is terminated without cause before the date, because the employee did not choose to leave. If the clause is silent, the employee may have to argue for it.

Do I have to pay back a retention bonus?

Only if the agreement says so and the repayment is lawful in your state. Bonuses paid on or after the stay date are usually not repayable. Bonuses paid upfront often carry a pro rata repayment if you resign early, which some states restrict.

Is a retention bonus taxed differently?

It is taxed as ordinary wages, but employers may withhold federal income tax at the flat 22 per cent supplemental rate when paid separately. That can be more or less than your actual tax rate; the difference is settled when you file your return.

What is the difference between a retention bonus and a sign on bonus?

A sign on bonus is paid for joining and often repayable if you leave soon after. A retention bonus is paid for staying through a period or milestone, and is usually forfeited rather than repaid if you leave before the date.

Can a retention bonus be paid if the project is delayed?

Only if the clause provides for it. A long stop date, after which the bonus is paid if the employee is still employed, protects the employee from delays outside their control. Without one, a slipped milestone can postpone the bonus indefinitely.
