Firefighter Retirement Eligibility: Age 50 with 20 Years or Any Age with 25 Years

The Two Paths to Voluntary Retirement

Federal firefighters under FERS qualify for immediate voluntary retirement through one of two service combinations under 5 U.S.C. § 8412(d):

• Age 50 with 20 years of creditable special category (covered) service
• Any age with 25 years of creditable special category (covered) service

These thresholds are significantly more favorable than standard FERS rules, where the earliest voluntary retirement is typically at your Minimum Retirement Age (56–57) with 30 years of service. A firefighter who started at 25 could theoretically retire at 50 — a full six or seven years before a standard FERS employee with the same start date.

What Counts as Covered Service

Only service in positions designated as 6(c) primary or secondary firefighter positions counts toward the 20-year or 25-year threshold. This is not your total federal service — it is specifically the time you spent in positions where fire suppression or fire management was the primary or secondary duty and the position carried 6(c) special provision coverage.

Time in non-covered federal positions (a detail to a regional office administrative role, a temporary assignment outside the fire organization) accrues as standard FERS service. It still counts toward your annuity computation, but at the standard 1.0% rate, not the enhanced 1.7% rate, and it does not count toward the 20 or 25-year covered service threshold.

Military buyback time adds to your total federal service but does not count as covered firefighter service.

Unused sick leave is credited toward total service time for annuity computation but cannot be used to meet the 20-year or 25-year eligibility requirement.

Can Firefighters Retire Before 50?

Yes, if you reach 25 years of covered service before age 50. A firefighter who entered a permanent 6(c) position at age 22 and served continuously would hit 25 years at age 47. Under the "any age with 25 years" rule, they could file for immediate voluntary retirement at that point.

In practice, very few firefighters accumulate 25 years of unbroken covered service before 50. The more common path involves seasonal time early in the career — years that may or may not be creditable depending on appointment type and whether deposits were made for pre-1989 service. A firefighter who started as a temporary seasonal in their early 20s and converted to permanent at 28 likely has only the post-conversion years counting toward covered service, unless pre-1989 deposits were completed.

Verifying Your Covered Service Total

Block 31 on your SF-50 is the Service Computation Date (Leave); it reflects service used for leave accrual, not your retirement-creditable or 6(c)-covered-service total. To determine your 6(c) covered service total, you need to:

1. Pull every SF-50 from your eOPF
2. Identify which periods carry retirement Code K in Block 30
3. Total only the Code K periods, subtracting any excess LWOP beyond six months per calendar year
4. Cross-check against your position descriptions to confirm each period's 6(c) designation

If you transferred between agencies, changed series, or moved from primary to secondary positions, this audit becomes critical. A period coded as standard FERS (Code 1 or Code 8) does not count toward the 20 or 25-year threshold even if you were actually performing firefighter duties.

The Annuity You Get at Each Threshold

The enhanced annuity formula for firefighter retirement pays 1.7% of your high-3 average salary for each year of covered service up to 20 years, plus 1.0% for each year beyond 20. Any non-covered service accrues at 1.0% (or 1.1% if you are age 62 with 20+ total years).

For a firefighter retiring at age 50 with exactly 20 years of covered service and a high-3 of $90,000:

• 20 years × 1.7% × $90,000 = $30,600 per year

For a firefighter retiring at any age with 25 years of covered service and the same high-3:

• 20 years × 1.7% × $90,000 = $30,600
• 5 years × 1.0% × $90,000 = $4,500
• Total: $35,100 per year

Both retirees receive the FERS Special Retirement Supplement immediately upon separation, bridging the gap until Social Security begins at age 62.
