Federal Employee Leave — Annual Leave, Sick Leave, and FMLA

Federal civilian employees in the federal civil service earn paid annual leave based on years of service, starting at 13 days per year for new employees and reaching 26 days per year after 15 years. They also earn 13 days of paid sick leave each year, which accumulates without limit and can cover illness, medical appointments, or care for qualifying family members. Federal employees receive 11 paid holidays per year. They are also covered by the federal FMLA provisions, which provide up to 12 administrative workweeks of job-protected leave in a 12-month period for qualifying family and medical reasons. Since 2020, eligible employees have also been able to substitute up to 12 weeks of paid parental leave for unpaid FMLA leave following a qualifying birth or placement.

Current Law (2026)

Legal Authority

• 5 U.S.C. § 6303 — Annual leave accrual: rate increases with federal service — ½ day per pay period (<3 years), ¾ day per pay period (3–15 years), 1 day per pay period (15+ years)
• 5 U.S.C. § 6304 — Annual leave accumulation: unused annual leave carries over each year up to the maximum (240 hours for most employees; 720 hours for SES and certain senior officials); excess is forfeited at year-end unless the forfeiture resulted from exigency of the public business

Annual Leave: The Accrual System

Annual leave accrual is the most important leave benefit for new federal employees to understand. The rate jumps at two milestones:

• Years 0–3: 4 hours per pay period (26 pay periods = 104 hours = 13 days/year)
• Years 3–15: 6 hours per pay period (with a slight adjustment in the final pay period of the year) = approximately 160 hours = 20 days/year
• Year 15+: 8 hours per pay period = 208 hours = 26 days/year

Senior Executive Service (SES) members and political appointees at equivalent levels accrue leave at the 15+ year rate from their first day.

The "use or lose" rule means employees lose any annual leave above 240 hours (30 working days) at the start of each year. Employees approaching the ceiling should take leave before year-end — unless the excess leave was forced by "exigency of the public business" (an agency emergency), in which case it can be restored. Restored leave must be used within 2 years or it's forfeited permanently.

Lump-sum payment at separation: When you leave federal service — through resignation, retirement, or reduction in force — you receive a lump-sum cash payment for all unused annual leave, calculated at your rate of pay on the day of separation. A GS-13 employee with 240 hours of accrued leave receives roughly 6 weeks' pay in a lump sum. This makes annual leave carry-over genuinely valuable at retirement.

Sick Leave: The Unlimited Bank

Federal sick leave has no accumulation ceiling — it compounds indefinitely. Career federal employees who rarely use sick leave can accumulate thousands of hours over a career. This has two important consequences:

1. Long-term illness protection: Employees with large sick leave balances can cover extended illness (cancer treatment, recovery from surgery) without going into unpaid leave or losing their job.

2. Retirement credit: For employees under the Civil Service Retirement System (CSRS), unused sick leave is added to their creditable service at retirement — increasing the pension annuity. For Federal Employees Retirement System (FERS) employees retiring after January 1, 2014, unused sick leave is also fully creditable toward retirement computation at full value.

FMLA and Paid Parental Leave

Federal FMLA mirrors the private-sector concept in broad strokes: up to 12 administrative workweeks of unpaid, job-protected leave for qualifying reasons. Federal employees may elect to substitute eligible paid leave, such as annual leave or sick leave where otherwise permitted, for unpaid FMLA leave. Agencies do not simply convert every FMLA absence into paid leave automatically; the substitution rules depend on the type of leave and the reason for the absence.

Paid Parental Leave: As of October 1, 2020, eligible employees may use up to 12 administrative workweeks of paid parental leave for the birth, adoption, or foster placement of a child. This leave is not a separate free-standing benefit outside FMLA; it is a form of paid leave substituted for unpaid FMLA leave tied to a birth or placement event. Employees generally must have completed 12 months of qualifying federal service to be eligible for FMLA and therefore for paid parental leave, and they usually must sign a 12-week work-obligation agreement before using the benefit.

How It Affects You

If you're considering federal employment, the leave package represents significant total compensation. A GS-13 employee at 15+ years with 26 days of annual leave plus 13 days of sick leave plus 11 holidays receives 50 days of paid time off per year — substantially more than most private-sector jobs. Factor this into total compensation comparisons.

If you're in your first 3 years as a federal employee: You accrue annual leave at 4 hours per biweekly pay period (13 days/year). That feels limited compared to later tiers, but sick leave accrues simultaneously at 4 hours per pay period regardless of seniority — that's an additional 13 days/year that never expires and never has a "use it or lose it" ceiling. Prioritize building your sick leave balance during healthy years: it's your income protection during serious illness, covers family care under federal sick leave policy, and under FERS it converts to service credit at retirement. Two years of unused sick leave (roughly 416 hours) adds about 3 months to your calculated retirement annuity.

If you're planning your federal retirement timing: Your unused sick leave balance converts to additional service credit in your annuity calculation — 2,087 hours equals 1 full year of additional service. Every 174 hours of sick leave adds approximately 1 month. An employee retiring with 2,000 hours of accumulated sick leave effectively gains about 11.5 months of service credit, adding roughly 1.15% to a FERS annuity (the standard 1%/year formula) — worth several hundred dollars per year in additional lifetime retirement income. Ask your HR office for an OPM retirement estimate that includes your current sick leave balance before choosing your retirement date.

If you're a federal supervisor managing leave requests: FMLA designation and documentation rules matter, but the details turn on the employee's title 5 eligibility, the agency's notice process, and what type of paid leave the employee wants to substitute. Paid leave is not universally mandatory just because the absence qualifies for FMLA. When in doubt, document the request carefully and use current OPM guidance rather than relying on private-sector FMLA shorthand.

State Variations

This is exclusively federal law governing federal civilian employees. State and local government employees are subject to state-specific leave laws, which vary considerably. Note that Washington, D.C. government employees (separate from federal employees) are covered by D.C. law, not the federal system.

Implementing Regulations

• OPM annual leave fact sheets and guidance — OPM administers government-wide annual leave accrual, restoration, and carry-over policy for covered civilian employees.

• OPM sick leave guidance — OPM administers the government-wide rules on accrual, family-care usage, and retirement-service credit for unused sick leave.

• OPM FMLA guidance for most federal employees — OPM's federal FMLA materials explain eligibility, substitution of paid leave, medical certification, and military-family leave rules for title 5 employees.

• OPM paid parental leave guidance — OPM implements the substitution of paid parental leave for unpaid FMLA leave, including the work-obligation agreement and intermittent-use rules.

• 5 CFR Part 630 — Absence and Leave (147 sections across 17 subparts — OPM's complete implementing regulations for the federal leave system under 5 U.S.C. Chapter 63):

  • Subpart B — Annual and Sick Leave Definitions (12 sections): definitions of "pay period," "biweekly pay period," "day," and other terms used throughout Part 630; the full-time/part-time equivalency calculation for leave accrual
  • Subpart C — Annual Leave (10 sections): accrual rates — 4 hours per biweekly pay period for employees with fewer than 3 years of service; 6 hours (8 in final pay period) for 3–15 years; 8 hours for 15+ years; SES and equivalent positions accrue at 8 hours regardless of service; maximum biweekly carryover (240 hours for most; 360 for employees assigned overseas; 720 for SES); "use-or-lose" rule — annual leave in excess of the carryover cap is forfeited at the end of the leave year (December 31 for most); restored leave rules when forfeiture was due to administrative error, illness, or exigencies of public business
  • Subpart D — Sick Leave (8 sections): accrual at 4 hours per biweekly pay period with no maximum accumulation cap; permissible uses — personal medical needs, care of an immediate family member with a medical condition, bereavement leave for immediate family member deaths, adoption-related purposes; sick leave credited as civilian service for CSRS/FERS retirement computation (full credit under FERS since 2009)
  • Subpart E — Recredit of Leave (6 sections): when an employee is reappointed to the federal service after a break, previously forfeited annual leave may be recredited; the employing agency must recredit annual leave forfeited in the prior appointment if it would not have been forfeited but for the separation; sick leave from prior service is fully recredited
  • Subpart F — Home Leave (7 sections): additional annual leave (up to 15 days per year) for U.S. citizen employees serving in foreign countries in "difficult" or "hardship" assignments; intended to offset the cost and difficulty of returning home for rest and recreation during extended overseas tours
  • Subpart H — Funeral Leave (4 sections): up to 3 workdays of funeral leave for an immediate family member who dies on active military duty (this is separate from and in addition to sick leave for bereavement); may be taken in connection with the interment or memorial services; the 3-day limit is absolute — additional time requires use of annual or sick leave
  • Subpart I — Voluntary Leave Transfer Program (13 sections): allows employees with a medical emergency (their own or an immediate family member's) to receive donated annual leave from other employees in the same agency or, through interagency agreements, from other agencies; the employee must have exhausted all other available paid leave; donations are irrevocable; unused donated leave is returned to donors at the end of the medical emergency
  • Subpart J — Voluntary Leave Bank Program (16 sections): an alternative to the transfer program — agencies establish agency-wide leave banks to which employees voluntarily contribute annual leave; members in medical emergencies can withdraw from the bank; individual agencies choose whether to operate a bank, a transfer program, or both; CIA and a few defense agencies are excluded from these programs
  • Subpart K — Emergency Leave Transfer Program (18 sections — largest): OPM may establish a government-wide emergency leave transfer program when a presidentially declared major disaster or emergency threatens federal employees' jobs or lives; employees may donate annual leave to a special fund; affected employees can receive donations from any participating agency; unlike the voluntary bank, emergency donations are government-wide and designed for acute, geographically concentrated events
  • Subpart L — Family and Medical Leave (13 sections): implements FMLA for title 5 federal employees — 12 workweeks of unpaid leave per year for serious health condition (own or immediate family member), childbirth/adoption/foster placement, qualifying military exigencies; employees may substitute accrued paid leave (annual, sick, or PPL) during FMLA; medical certification requirements mirror FMLA private-sector rules; 26 weeks of military caregiver leave for employees caring for a seriously injured/ill servicemember
  • Subpart M — Disabled Veteran Leave (8 sections): employees with service-connected disability ratings of 30% or more receive up to 104 hours of disabled veteran leave during the first 12 months of employment (non-accruing; use it or lose it) — specifically for VA medical appointments and treatment related to the service-connected disability; enacted 2016
  • Subpart N — Administrative Leave (6 sections): excused absence (paid, non-chargeable to personal leave accounts) for activities including blood donation, voting, attending naturalization ceremonies, brief military duty, weather-related office closures when the employee is in a status other than weather/safety leave; agency heads determine specific administrative leave policies within OPM parameters; prior to 2016, administrative leave was largely unregulated — the Act now caps individual administrative leave at 10 days per year without agency head approval
  • Subpart O — Investigative Leave and Notice Leave (6 sections): created by Congress in 2017; agencies may place employees under disciplinary investigation on investigative leave (paid) or, after charges are filed, notice leave (also paid) rather than keeping them in a work status or placing them on administrative leave indefinitely; limits: investigative leave initially 70 days with extension to 90; notice leave for the duration of notice period for removal; quarterly reporting to OPM and Congress
  • Subpart P — Weather and Safety Leave (7 sections): a designated form of paid absence when employees cannot safely travel to or work at their duty station due to a weather or safety emergency; agencies may grant weather and safety leave to specific employees or all employees at a location; does not count against the 10-day administrative leave cap; distinct from office closure decisions — individual employees may be on weather and safety leave while others work
  • Subpart Q — Paid Parental Leave (8 sections): up to 12 weeks of paid parental leave (PPL) available by substituting PPL for unpaid FMLA leave in connection with a qualifying birth, adoption, or foster placement; PPL is paid at the employee's regular rate of pay; the employee must agree to work for at least 12 weeks after PPL ends (the "work obligation"); if the employee separates before completing the 12-week obligation, the PPL must be repaid unless a hardship waiver is granted; intermittent PPL requires agency agreement; PPL may be taken within 12 months of the qualifying event

• 5 CFR Part 610 — Hours of Duty: OPM rules establishing the structure of federal work schedules — the basic workweek, daily tour of duty, holiday observance, and scheduling accommodations that underlie the leave system (implements 5 U.S.C. Chapter 61):

  • § 610.111 — Basic workweek: the head of each agency must establish a basic workweek of 40 hours that does not extend over more than 6 days for full-time employees; this is the baseline work requirement from which overtime, leave, and holiday pay are calculated
  • § 610.121 — Standard work schedule: agencies must schedule employees on a 5-day, 8-hour-per-day tour whenever practicable; exceptions are permitted when operational requirements make the standard schedule impractical or when a different schedule would substantially reduce costs; the standard schedule is the presumption — deviations require justification
  • § 610.122 — Educational schedule variations: agencies may authorize a special tour of duty (not less than 40 hours per week) to allow an employee to take courses at a college, university, or other educational institution; the schedule modification accommodates learning without reducing the 40-hour work requirement or creating an overtime obligation
  • § 610.123 — Travel on official time: travel required in connection with official duty should occur during regular duty hours whenever practicable; when an employee must travel during non-duty hours and is not entitled to overtime pay for the travel time, OPM rules address how the travel hours relate to compensatory time entitlement
  • § 610.201 — Holiday identification: agencies determine which days are federal holidays under 5 U.S.C. § 6103 and Executive Order 11582; there are 11 federal holidays (New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas Day)
  • § 610.202 — In-lieu-of holiday: when a designated holiday falls on a Saturday, most full-time employees on Monday–Friday schedules observe the preceding Friday as their holiday; when a holiday falls on Sunday, the following Monday is observed; part-time employees and employees with non-standard schedules have in-lieu-of-holiday rules that map the holiday to their scheduled workday nearest the actual holiday

  Part 610's hours-of-duty framework is the scheduling infrastructure that makes the Part 630 leave system function — leave is measured in hours (or days of a defined tour), and overtime calculations depend on the basic workweek definition. The Saturday/Sunday in-lieu-of holiday rules explain a recurring source of federal employee pay questions: when Christmas falls on a Wednesday, full-time employees get December 25 off; when it falls on Saturday, they get December 24 (Friday) off; when it falls on Sunday, they get December 26 (Monday) off. These rules are consistent and predictable — but often misunderstood by employees who haven't encountered the in-lieu-of holiday concept before.

Pending Legislation

No major structural rewrite appears to be the operative current-law story as of April 8, 2026. The more important practical issues are implementation questions under existing OPM guidance, especially for intermittent paid parental leave, service-credit determinations, restored leave, and supervisor handling of FMLA-related requests.

Recent Developments

• Paid parental leave remains the biggest modern structural change: OPM's paid parental leave guidance continues to emphasize that PPL is available only by substituting it for unpaid FMLA leave tied to a birth or placement event.
• The 12-week post-leave work obligation is a real condition of use: Employees generally must agree to return to work for at least 12 weeks after PPL concludes, unless a statutory exception or waiver basis applies.
• Intermittent PPL is limited: OPM guidance allows intermittent or reduced-schedule use of paid parental leave only when the employing agency agrees.
• Core annual and sick leave accrual rules remain stable: The 4/6/8-hour annual leave structure, unlimited sick-leave accumulation, and 240-hour general carryover cap remain the baseline framework in 2026.
