Federal Employee Annual Leave: Accrual, Use, and Rules
Federal employees earn annual leave as a statutory entitlement governed by Title 5 of the U.S. Code and administered through the Office of Personnel Management (OPM). The accrual rate, rules for use, carryover limits, and payout eligibility all depend on specific variables — primarily years of service and employment category. This page covers how annual leave accrues across service tiers, how it interacts with other federal leave policies and types, and where the rules create decision points that employees and supervisors must navigate carefully.
Definition and scope
Annual leave is paid time off that federal civilian employees accrue each pay period and may use for personal needs, including vacation, personal business, and illness when sick leave is exhausted. The entitlement is established under 5 U.S.C. §§ 6301–6311, which sets the legal framework for earning, using, and cashing out annual leave across the federal workforce.
Scope is broad but bounded. Most full-time and part-time employees in the competitive and excepted service accrue annual leave, as do Senior Executive Service members. Employees paid from appropriated funds fall under this framework; certain non-appropriated fund positions and temporary appointments of 90 days or fewer are excluded from standard accrual (OPM Leave Administration). Intermittent employees — those with no fixed work schedule — do not accrue annual leave at all.
The federal annual leave system is distinct from sick leave, which is tracked in a separate balance and carries different rules. It is also separate from compensatory time, credit hours, and other leave-adjacent categories covered under the broader federal employee benefits overview.
How it works
Annual leave accrues on a biweekly basis across the federal government's 26 pay periods per year. The accrual rate is tiered by years of creditable federal civilian service:
- 0–2 years of service: 4 hours per pay period (13 days per year)
- 3–14 years of service: 6 hours per pay period, plus 4 hours in the final pay period of each leave year (19.5 days per year)
- 15 or more years of service: 8 hours per pay period (26 days per year)
These rates apply to full-time employees. Part-time employees accrue leave proportionally based on their scheduled hours. An employee in a 20-hour-per-week position accrues at half the rate of a full-time employee in the same service tier.
Carryover limits are a defining structural feature of the system. Most federal employees may carry over a maximum of 240 hours (30 days) of annual leave from one leave year to the next. Employees stationed overseas may carry over up to 360 hours. Senior Executive Service members are also subject to the 240-hour cap in most circumstances (OPM Leave Administration). Hours above the applicable ceiling that remain unused at the end of the leave year are forfeited — a mechanism commonly referred to as "use or lose."
Creditable service for accrual purposes is not limited to current federal employment. Prior military service, prior federal civilian service (even with breaks), and certain other qualifying periods may be credited toward an employee's service tier. Verification of creditable service is processed through the employing agency's human resources office.
Annual leave must generally be approved in advance, and agencies retain scheduling authority. A supervisor may deny a leave request based on mission requirements, though denial must be consistent with applicable collective bargaining agreements and agency policy. Employees represented by unions may have negotiated protections around leave scheduling — see federal employee unions and collective bargaining for context.
Common scenarios
Use-or-lose situations: An employee approaching the 240-hour carryover ceiling late in the leave year must use excess leave before the final day of the leave year or forfeit it. OPM guidance allows agencies to "restore" forfeited annual leave in specific circumstances — including when leave was scheduled in advance and was subsequently denied due to agency exigency, or when illness prevented use. Restored leave is placed in a separate account with a fixed expiration date (typically 2 years from the date of restoration).
Separation from federal service: Upon separation — whether through resignation, retirement, or reduction in force — employees receive a lump-sum payment for all accrued, unused annual leave. The payment is calculated at the employee's rate of basic pay at the time of separation. This payout is taxable as ordinary income. Employees entering federal service from private employment receive no credit for prior non-federal leave balances.
Extended medical or personal absence: When sick leave is exhausted during a prolonged medical situation, employees may substitute annual leave to maintain pay continuity. The Family and Medical Leave Act (FMLA), which covers most federal employees, may run concurrently with paid leave use — agencies may require substitution of accrued paid leave during FMLA-protected absences.
New employees and probationary periods: Employees begin accruing annual leave from their first pay period, including during the probationary period for federal employees. However, if an employee separates before completing one full pay period, no leave is earned for that partial period.
Decision boundaries
Competitive service vs. excepted service: Both categories accrue annual leave under the same statutory framework. The distinction that matters operationally is appointment type. A temporary appointment of 90 days or fewer does not carry annual leave accrual rights; a temporary appointment of more than 90 days does. This boundary is precise and consequential — a single-day difference in appointment length can affect leave eligibility.
Senior Executive Service vs. General Schedule: SES members accrue annual leave at the 8-hours-per-pay-period rate regardless of years of service, unlike General Schedule employees who climb through three tiers. The carryover ceiling is the same — 240 hours — for both populations under standard domestic assignments. For more on how SES employment differs structurally, see the Senior Executive Service overview and the General Schedule GS pay system for comparison.
Leave year vs. calendar year: The federal leave year is not the same as the calendar year. OPM defines the leave year as beginning with the first full biweekly pay period of the calendar year and ending with the last full biweekly pay period that falls before January 1. The use-or-lose deadline falls on the final day of the leave year as defined by OPM — not December 31.
Restoration eligibility: Not all forfeited leave qualifies for restoration. Leave is only restorable if the forfeiture resulted from: (1) an administrative error, (2) an exigency of the public business where leave was scheduled in advance and then denied, or (3) an illness that prevented use of previously scheduled leave. Employees who simply failed to schedule or use leave before the deadline have no restoration claim (5 U.S.C. § 6304).
