Understanding the FERS Special Retirement Supplement
The FERS Special Retirement Supplement (SRS)—often called the "annuity supplement"—is one of the most valuable yet misunderstood benefits available to federal employees. For eligible retirees, it can provide an extra $500 to $1,500+ per month to bridge the gap between federal retirement and Social Security eligibility.
However, many federal employees who expect to receive the supplement discover too late that they don't qualify, or that working part-time in retirement eliminates the benefit entirely. This guide explains exactly how the FERS Supplement works, who qualifies, how it's calculated, and critical mistakes to avoid.
What Is the FERS Special Retirement Supplement?
The FERS Special Retirement Supplement is designed to bridge the income gap between FERS retirement and Social Security eligibility at age 62. Since FERS employees don't receive the more generous CSRS pension, the supplement helps replace some of that lost income during the early retirement years.
Think of it as a temporary Social Security payment before you're eligible for actual Social Security.
Key Characteristics
Temporary benefit: Only paid until age 62 (when you can claim Social Security)
Approximate amount: Roughly equivalent to the Social Security portion of your FERS retirement benefit
Subject to earnings test: Reduced or eliminated if you earn too much after retirement
Not automatic: Only certain retirement scenarios qualify
Eligibility Requirements
Not all FERS retirees receive the supplement. You must meet specific age and service requirements.
You qualify if you retire under one of these scenarios:
-
- Minimum Retirement Age (typically 56-57) + 30 years
- Most common qualification path
-
- Age 60 + 20 years of service
- Standard for many federal employees
-
- Age 50 with 20 years of covered service, OR
- Any age with 25 years of covered service
- Must be in special provisions category
How Is the FERS Supplement Calculated?
The calculation estimates what your Social Security benefit would be at age 62 if your only earnings were your federal service.
The Formula:
(Years of FERS service ÷ 40) × Estimated Social Security benefit at age 62
Real-World Example: 30-year federal career
- FERS service: 30 years
- OPM Estimated Social Security at 62: $2,000/month
- Calculation: (30 ÷ 40) × $2,000 = $1,500/month
- Annual supplement: $18,000
The Earnings Test: The Trap That Eliminates Your Supplement
This is where many FERS retirees get caught by surprise. The FERS Supplement is subject to the Social Security earnings test—if you work after retirement and earn too much, your supplement is reduced or eliminated entirely.
For 2026, the annual earnings limit is $24,480 (adjusted annually for inflation). If earnings exceed this amount, the supplement is reduced by $1 for every $2 earned over the limit.
Many federal retirees plan to work part-time to supplement income during early retirement—but this can eliminate the FERS Supplement entirely.
Income Does NOT count:
- FERS pension/annuity
- Social Security benefits
- TSP withdrawals
- Investment income (dividends, interest, capital gains)
- Rental income (if not self-employment)
- Pensions from other sources
When Does the FERS Supplement Start and End?
If you retire at MRA or later: Your supplement starts with your first annuity payment.
If you retire under VERA before MRA: Your supplement doesn't start until you reach MRA.
Your supplement automatically stops at age 62, regardless of when you claim Social Security.
Even if you delay Social Security until age 67 or 70 for a larger benefit, your supplement still ends at 62.
Special Provisions Employees: Enhanced Benefits
If you're in a special provisions category (law enforcement officer, firefighter, air traffic controller, etc.), you receive more favorable treatment:
- Retire at age 50 with 20 years of special provisions service
- Retire at any age with 25 years of special provisions service
- Supplement starts immediately upon retirement
For special provisions retirees, the supplement typically continues until the later of:
- Age 62, OR
- One year after retirement
This means if you retire at age 55, your supplement continues until age 62. If you retire at age 61, it continues until age 62 (one year after retirement).
FERS Supplement and VERA: What You Need to Know
If you're offered VERA (Voluntary Early Retirement Authority), understanding how it affects the supplement is critical.
If you retire under VERA before reaching MRA:
- Your pension starts immediately
- Your supplement does NOT start until you reach MRA
- You face an income gap of potentially 5-10 years
If you retire under VERA at or after your MRA:
- Both pension and supplement start immediately
- Supplement continues until 62
- No income gap
This is one reason why waiting until MRA for VERA (if possible) can make financial sense.
Planning Tip
The supplement increases your taxable income during early retirement years (before 62). This might be an opportunity for:
- Roth conversions while in a lower bracket (after 62 when supplement stops)
- Strategic TSP withdrawal timing
- Tax-loss harvesting in taxable accounts
