Lump-sum annual leave payout: what to expect

A lump-sum annual leave payout is a one-time cash payment for the annual leave you have not used. You receive it when you separate from federal service, whether you retire or resign. It pays your full unused balance at once.

It is not part of your pension. The payout comes from your agency, not OPM, and it is separate from your FERS annuity. Think of it as your last pay item, not a retirement benefit.

Unused sick leave is handled differently. It converts to service credit toward your pension, not to cash. The sick and annual leave lesson covers that split in detail.

The rest of this lesson covers the details: how the payout is calculated, what counts toward it, how it is taxed, and when it arrives. For how your date changes the payout, see timing your retirement date.

Your agency calculates the payout as the pay you would have received had you stayed and used the leave. OPM projects your leave forward from your separation date. It counts your hours across future workdays and holidays until the leave runs out.

Each hour is paid at your hourly rate of basic pay. That rate includes your locality pay and any special salary rate. So the payout reflects your real pay, not just base salary.

Raises during the projected period count too. If an across-the-board or locality pay adjustment takes effect while your leave is projected forward, the hours after it are paid at the higher rate. A later date can push more hours past a January raise.

For the date strategy behind that raise timing, see timing your retirement date. This lesson focuses on the payout itself.

Your payout includes more leave than you can normally keep. It pays your carryover balance, the use-or-lose hours above your ceiling, and any restored leave. Nothing in your annual leave account is left behind when you separate.

Most employees can carry up to 240 hours of annual leave into a new leave year. Overseas employees can carry 360 hours, and SES, SL, and ST employees can carry 720. Anything above your ceiling is use-or-lose.

Use-or-lose leave is paid, not lost, at separation. In a normal year, hours above your ceiling are forfeited if unused by the leave year’s end. When you separate, those hours are cashed out instead.

Restored leave counts too. Leave that was forfeited and later restored, after an emergency or an administrative error, is added to the payout. So your final check can include leave from more than one source.

Your lump-sum payout is taxed as ordinary income in the year you receive it. The IRS treats it as wages, reported on your W-2. There is no special or lower tax rate for it.

It is withheld as supplemental wages. Because the payout is paid separately from regular pay, your agency can withhold federal income tax at a flat supplemental rate. Social Security and Medicare taxes apply too, like any wages.

A large payout can affect your bracket. Adding weeks of pay in one year can push part of your income into a higher tax bracket. The withholding may also differ from your final tax bill, so you could owe more or get a refund.

State taxes vary. Some states tax the payout as wages, others do not, and the rules differ by where you live. Many federal retirees set aside part of the payout for taxes to avoid a surprise at filing.

You usually receive the payout within a pay period or two after you separate. It comes as a separate payment from your final salary check. The exact timing depends on your agency’s payroll cycle.

Returning to federal service has a catch. Suppose you are reemployed under a federal leave system before your lump-sum leave period ends. You must refund part of the payout, covering the days from your return to the period’s end.

The leave then comes back to you. The hours you refund are re-credited to your new annual leave account. So you do not lose the leave; you simply hold it again instead of the cash. Restored leave is excluded from the refund.

This only matters if you go back. Most retirees never trigger a refund, because they do not return to a covered federal job. If you might, the timing of your return against the lump-sum period is what counts.

Expect a sizable, one-time check, taxed as wages, arriving shortly after you separate. To plan for it, estimate your hours, apply your hourly rate, and set aside part for taxes. The date you pick can change the total.

Start with your projected hours. Add your carryover balance, your use-or-lose hours, and any restored leave. That total, times your hourly rate of basic pay, is a rough estimate of the payout before tax.

Then plan for the tax. Because the payout lands as ordinary income in one year, setting aside a portion avoids a surprise at filing. A larger balance means a larger tax bill in that year.

There is no single right way to time it; it depends on your leave, your taxes, and your plans. To see how your full retirement picture fits together, run your free readiness score. For the date mechanics, see timing your retirement date.
