Learn exactly how the FERS annual leave lump sum payout is calculated, taxed, and timed at federal retirement to maximize your check.
Quick Summary
- When you retire, all unused annual leave is paid out as a single lump-sum check.
- The payout is based on your hourly rate at the time of separation, including locality pay.
- Most employees can receive up to 448 hours in one payment. At $100,000/year, that’s roughly $21,500.
- The payment is fully taxable as ordinary income and it cannot go into your TSP or an IRA.
- Timing your retirement to maximize your leave balance can significantly increase your payout.
For most of your federal career, annual leave is used for vacation days, personal appointments, and the occasional long weekend. But as you approach retirement, that balance takes on a different meaning. For employees retiring under both FERS and CSRS, every unused hour of annual leave converts into a direct cash payment when you separate. Understanding how that payment is calculated, when it arrives, and how it’s taxed can help you make one of your final federal decisions a smart one.
How Annual Leave Accrues During Your Federal Career
Annual leave builds up every two weeks throughout your federal career, and the rate increases with your years of service. Early-career employees with fewer than three years earn four hours per pay period, which works out to 13 days per year. Between three and fifteen years, that rises to six hours per period, or about 19.5 days annually. Once you cross the fifteen-year mark, you earn eight hours per period, which equates to a full 26 days each year. Members of the Senior Executive Service (SES), Senior Level, and Scientific/Professional pay plans earn at that top rate from their first day on the job.
| Years of Service | Hours Earned Per Pay Period | Days Earned Per Year |
| Less than 3 years | 4 hours | 13 days |
| 3 to 15 years | 6 hours | ~19.5 days |
| 15 or more years | 8 hours | 26 days |
| SES / SL / ST (any tenure) | 8 hours | 26 days |

How Much Annual Leave Can You Carry Into Retirement?
There is a cap on how many hours carry over from one leave year to the next, so unused hours above that cap are forfeited at the end of each year. For most federal employees, the maximum carryover is 240 hours, the equivalent of 30 days. If you’re stationed overseas, that limit rises to 360 hours. SES, Senior Level, and Scientific/Professional employees can carry as many as 720 hours.
Annual Leave: Use It or Lose It
The carryover limit is key as you approach retirement, because the more you hold onto, the larger your payout. If your balance is above the cap at the end of the leave year and you haven’t taken time off, you lose those hours with no compensation. Building up to, but not over, the maximum in the year before retirement is a straightforward way to protect your payout.
| Employee Category | Maximum Hours Carried Over | Equivalent Days |
| Most full-time federal employees (CONUS) | 240 hours | 30 days |
| Employees stationed overseas | 360 hours | 45 days |
| SES / SL / ST employees | 720 hours | 90 days |

How Is the Annual Leave Lump Sum Payout Calculated?
When you retire, every hour of unused annual leave is multiplied by your hourly rate of pay at the time of separation. That rate includes your basic pay and locality pay, and any across-the-board raises that took effect before your retirement date. It does not include overtime or bonuses.
Here’s what that looks like in practice. Say you retire with 240 hours carried over from the prior year and you’ve accrued another 208 hours during the current leave year for a total of 448 hours. If your annual salary is $100,000, your hourly rate works out to roughly $48.08. Multiply that by 448 hours and your lump-sum check comes to approximately $21,540. That’s more than eleven weeks of base pay delivered in a single payment.
Annual Leave Lump-Sum During Interim Status
For many federal retirees, that payment also serves a practical purpose: it arrives while you’re waiting for your first full FERS pension payment. Because OPM typically takes four to six weeks (and sometimes longer) to process a new retirement claim and issue your first full annuity check, the annual leave lump sum often provides a solid cushion during that gap. Planning your leave balance with this bridge in mind is worth doing well before you submit your retirement paperwork. Retiring from the government means going from a biweekly budget to a monthly one so managing income sources after you leave federal service is an important skill to develop around this time.
How to Maximize Your Annual Leave Payout Before Retirement
The timing of your retirement date relative to the leave year can make a meaningful difference in your payout. The federal leave year does not follow the calendar year exactly. It starts with the first full pay period of January. Employees who retire at or near the end of the leave year can combine the full year’s accrual with their maximum carryover balance, producing the largest possible payout.
A few practical steps worth considering in the one to two years before your retirement date:
- Track your running balance against the carryover cap and take leave before the end of each leave year if you’re at risk of forfeiting hours
- Avoid using large blocks of annual leave in the final months if your balance is below the maximum and you want to build it up
- Confirm your retirement date with your agency’s HR office so it aligns with a pay period boundary. Small adjustments in timing can add dozens of hours, and thousands of dollars, to your final payout.
Is the FERS Annual Leave Lump Sum Payment Taxable?
Yes. The lump-sum annual leave payment is fully taxable as ordinary income in the year you receive it. Federal income tax and Medicare taxes are withheld. Social Security taxes may or may not apply depending on whether you’ve already reached the annual wage base by the time the payment is issued.
One situation worth knowing about: if you retire late in the calendar year, your lump-sum payment may push your total income higher than usual for that tax year. If your normal salary plus the lump sum crosses into a higher bracket, you could owe more at tax time than you expect. This isn’t a reason to avoid building your leave balance, but it is worth factoring into your tax planning in the year you retire.
Because of this, the lump-sum payment cannot be rolled into your Thrift Savings Plan (TSP) or an Individual Retirement Account (IRA). It is treated as regular wages, withheld and paid out like a paycheck. There is no option to defer it.
What Happens to Annual Leave If You Return to Federal Service?
There is a specific rule for retirees who return to federal work: if you are reemployed by the federal government before the period covered by your lump-sum payment has passed, you must return the portion of the payment that overlaps with your reemployment date. Those hours are then added back to your leave balance as a new federal employee. This situation is uncommon, but it applies to anyone considering a return to government service shortly after retirement.
Does This Apply to CSRS Employees Too?
Yes. Federal employees covered by the Civil Service Retirement System (CSRS) receive the same annual leave lump-sum payout under the same formula: unused hours multiplied by the hourly rate of pay at separation. The accrual rates, carryover limits, and tax treatment described in this article apply to both types of employees.
Frequently Asked Questions About the Unused Annual Leave Payout
How is the FERS annual leave lump sum calculated?
Multiply your unused annual leave hours by your hourly rate of pay at the time of retirement. Your hourly rate is your annual salary (including locality pay) divided by 2,087. Overtime and bonuses are not included.
How much annual leave can I cash out when I retire?
Most federal employees can cash out up to 448 hours: 240 hours carried over from the prior year plus up to 208 hours accrued during the current leave year. SES and overseas employees have higher carryover limits and therefore can receive larger payouts.
Is the federal employee annual leave payout taxable?
Yes, fully. The payment is taxed as ordinary income in the year you receive it. Federal income tax and Medicare are withheld. It cannot be rolled into a TSP or IRA.
When will I receive my annual leave lump sum payment?
OPM typically processes the lump-sum payment within a few weeks of your retirement date, often before your first FERS annuity check arrives. It is paid separately from your pension and arrives as a one-time payment.
What is the best time of year to retire to maximize my annual leave payout?
Retiring at or near the end of the federal leave year allows you to combine your full carryover balance with the current year’s accrual. The leave year ends with the last full pay period of December, so late December retirements often produce the largest possible payout. (This is why there is often a surge of new retirement applications at OPM at this time of year.)
Can I roll my annual leave lump sum into my TSP or an IRA?
No. The lump-sum payment is treated as regular wages and cannot be directed into a retirement account. It is subject to withholding and paid out like a final paycheck.
Next Steps: Make the Most of Your Annual Leave Before You Go
Your annual leave balance is one of the few retirement benefits you can actively build in the years leading up to separation. Knowing your carryover limit, tracking your accrual rate, and choosing a retirement date that captures the full leave year are all practical steps that cost nothing to take.
The result can be a lump-sum check that smooths the transition into retirement and gives you financial breathing room while your pension gets processed. It is also important to know the difference between unused sick leave and unused annual leave for both are treated differently when you retire.
