Unlike employees covered by the older Civil Service Retirement System (CSRS), FERS employees pay into Social Security throughout their federal careers and are entitled to Social Security benefits in retirement. The timing of when you claim Social Security is one of the most consequential financial decisions you'll make — and it interacts with your FERS annuity in important ways. This guide covers the key concepts.
Social Security Basics for FERS Employees
As a FERS employee, you pay Social Security taxes on your federal salary, just as private-sector employees do. Your Social Security benefit is based on your lifetime earnings record — including both federal and any non-federal employment.
Full Retirement Age (FRA)
Your Full Retirement Age is 66 or 67 depending on your birth year. Claiming at FRA gives you 100% of your earned benefit.
Early Claiming (Age 62)
You can claim Social Security as early as age 62, but your benefit is permanently reduced — by up to 30% if your FRA is 67.
Delayed Claiming (Up to Age 70)
For every year you delay claiming past your FRA, your benefit increases by 8% per year. Waiting until age 70 maximizes your monthly benefit.
The FERS Special Retirement Supplement
FERS employees who retire before age 62 with an immediate, unreduced annuity may be eligible for the FERS Special Retirement Supplement (SRS). This supplement approximates the Social Security benefit you earned from federal service and bridges income until you reach age 62.
Who Qualifies
Employees who retire at their MRA with 30+ years, at age 60 with 20+ years, or under certain early retirement authorities. Not available for MRA+10 retirements.
Earnings Test Applies
The SRS is subject to the Social Security earnings test. If you have earned income above the annual exempt amount, your SRS is reduced.
Ends at Age 62
The SRS stops automatically when you reach age 62, regardless of whether you claim Social Security at that point.
Breakeven Analysis
The breakeven analysis helps you think about the trade-off between claiming early (more years of payments, smaller amount) versus claiming later (fewer years of payments, larger amount).
The Basic Concept
If you claim early, you receive smaller payments for more years. If you delay, you receive larger payments for fewer years. The breakeven point is where the cumulative lifetime benefit is equal.
Typical Breakeven
The breakeven between claiming at 62 versus 67 is typically around age 78–80. If you expect to live past that age, delaying may produce more lifetime income.
Other Factors
The breakeven analysis is a starting point, not the whole picture. Spousal benefits, survivor benefits, tax implications, and your overall income needs all affect the optimal claiming strategy.

Important Federal Rules to Know
- FERS employees are not subject to the Windfall Elimination Provision (WEP) or Government Pension Offset (GPO) — those apply to CSRS employees

- You can work and receive Social Security after FRA with no earnings test penalty
- Social Security benefits receive annual Cost of Living Adjustments (COLAs)
Questions to Consider
- What is my Full Retirement Age, and what is my estimated benefit at FRA versus age 62 and age 70?
- Will I be eligible for the FERS Special Retirement Supplement, and how long will it last?
- Does my spouse have Social Security benefits, and how does spousal or survivor benefit strategy affect our timing decision?
- What is my breakeven age, and how does my health and family history factor into the analysis?
- How will Social Security income affect the taxability of my other retirement income?
