Unused Annual Leave at Federal Retirement: How the Lump-Sum Payment Works

A federal retirement date can affect more than the start of an annuity. It also closes out payroll, leave, insurance deductions, and personnel records. One of the largest final-payroll items for some employees is the payment for unused annual leave.

Employees often describe this as “cashing out” leave, but the federal calculation is more specific than multiplying a leave balance by a current hourly rate. The agency generally projects the unused annual leave across a period after separation and calculates the pay the employee would have received during that period.

That distinction can matter when the projected period crosses holidays, scheduled pay adjustments, or other changes in pay. It also explains why the payment comes from the former agency’s payroll operation rather than from the Office of Personnel Management.

What Happens to Annual Leave at Retirement?

Under OPM’s general rules, an employee covered by the federal annual-leave program is entitled to a lump-sum payment for accumulated and accrued annual leave when separating from federal service with a break of at least one full workday. Retirement is a qualifying separation.

The payment generally covers the annual leave credited to the employee at separation. OPM defines accumulated and accrued annual leave to include regular annual leave, restored annual leave, and use-or-lose annual leave that has not yet been forfeited. Advanced leave and donated leave are not treated the same way.

The agency must verify the balance before paying it. That is one reason employees should compare their final leave-and-earnings statements with agency records while they still have access to payroll and human-resources systems.

How the Lump-Sum Leave Period Works

The lump-sum leave period is the span of time the unused annual leave would have covered if the employee had remained employed and used the leave. The agency projects that period beginning with the first workday after separation and applies the employee’s established tour of duty.

The payment generally equals the pay the employee would have received during that projected period. Depending on the employee’s position and pay system, the calculation can include applicable basic pay and certain other forms of pay that would have been received while on annual leave.

This is why a simple estimate based only on current hourly pay may not match the agency’s result. The official calculation depends on the verified number of hours, the employee’s work schedule, the dates covered by the projected period, and the pay rules that apply to the position.

Can a Pay Adjustment Affect the Calculation?

OPM’s guidance says agencies calculate the payment using the pay the employee would have received during the lump-sum leave period. If an applicable pay adjustment takes effect during that projected period, the agency may need to apply the appropriate rate to the portion of leave falling after the effective date.

That does not mean a particular retirement date is automatically better. Retirement eligibility, annuity commencement, payroll schedules, agency processing, work obligations, and individual circumstances are separate considerations. Benefit Reviews does not recommend a separation date or calculate an expected payout.

What About Holidays?

The agency projects annual leave across workdays and holidays within the lump-sum period according to OPM’s calculation rules. A holiday can affect the pay represented within the projected period, but it does not create extra annual-leave hours or change the employee’s verified leave balance.

Employees should be cautious with online shortcuts that promise a specific payout based only on the number of holidays near a retirement date. The payroll office must apply the employee’s actual tour of duty, separation date, leave balance, and pay rules.

Annual Leave and Sick Leave Are Not Paid the Same Way

Unused sick leave is not included in the annual-leave lump-sum payment. For an eligible FERS or CSRS retirement, unused sick leave may instead be used in the annuity computation under applicable retirement rules after eligibility and service are otherwise established.

Sick leave does not generally create retirement eligibility by itself, and the conversion of sick-leave hours is a separate process from the annual-leave payout. The Sick Leave Conversion Calculator illustrates the OPM time conversion for educational purposes without determining eligibility or an annuity amount.

How Use-or-Lose Leave Fits In

Use-or-lose annual leave is leave above the employee’s applicable annual ceiling that must generally be used by the end of the leave year to avoid forfeiture. If that leave is still credited and has not been forfeited when the employee separates, OPM’s definition allows it to be included in the lump-sum payment.

Leave already forfeited is not automatically restored because an employee later retires. Restoration is governed by separate rules, deadlines, scheduling requirements, and agency findings. Employees with a disputed or recently restored balance should obtain written confirmation from their agency.

When Is the Payment Issued?

The former agency—not OPM—calculates and issues the annual-leave payment. OPM notes that many payments are issued within one or two pay cycles after retirement, but agency offboarding, leave-account audits, payroll corrections, and unusual records can extend the timeline.

A retirement annuity and an annual-leave payment therefore move through different systems. A person can receive one before the other. Our guide to OPM retirement processing explains the separate handoff from the agency to OPM.

What If the Employee Returns to Federal Service?

If a person is reemployed by the federal government before the projected lump-sum leave period expires, OPM rules generally require repayment of the portion covering the period from reemployment through the original expiration date. After the required refund is paid, the corresponding annual-leave hours are generally recredited.

Restored annual leave included in the original lump-sum payment has a special rule and is not subject to that refund requirement. A returning employee should work directly with the gaining agency because the repayment and recredit depend on the official dates and payroll records.

Why the Deposit May Differ From the Gross Calculation

The amount deposited into a bank account may be lower than the gross lump-sum calculation because payroll withholding and other applicable deductions can affect the net payment. The payment can also arrive separately from the final salary payment.

Tax treatment depends on current law and individual circumstances. Employees should use the agency’s payroll statement and year-end tax forms rather than treating an informal leave estimate as a net-payment or tax calculation.

Records to Review Before Separation

  • The most recent leave-and-earnings statement and its annual-leave balance
  • Any separate restored-leave account and its expiration information
  • Previously approved leave that may post before the separation date
  • The official separation date and final payroll cutoff
  • The agency payroll and human-resources contact information to keep after system access ends

Employees can also save copies of relevant personnel and retirement records using the organizational approach in the Retirement Road Map. The goal is not to calculate the payment independently, but to preserve enough information to recognize and question a discrepancy.

Common Questions

Is unused annual leave paid when a federal employee retires?

Employees covered by the federal annual-leave program are generally entitled to a lump-sum payment for accumulated and accrued annual leave when they separate for retirement. The employing agency calculates and issues it.

Is sick leave included in the payment?

No. OPM states that the lump-sum payment is for unused annual leave and does not include unused sick leave. Sick leave is handled under separate retirement-service-credit rules when applicable.

Does use-or-lose annual leave count?

Use-or-lose annual leave that remains credited and has not yet been forfeited can be included. Leave already forfeited is a separate issue, and restoration depends on the applicable rules and agency records.

Who handles a delayed or incorrect payment?

The former agency’s payroll or human-resources office should be the first contact. OPM does not calculate or issue the annual-leave lump-sum payment.
