Understanding the FERS Special Retirement Supplement
Last reviewed: September 2026 · Educational, not individual advice
The FERS Special Retirement Supplement pays eligible federal retirees a bridge income from retirement until age 62, roughly your years of FERS service divided by 40, times your estimated Social Security benefit at 62. It stops at 62 no matter when you claim Social Security, and in 2026 wages above $24,480 reduce it by $1 for every $2 you earn.
The supplement, often called the annuity supplement, is one of the most valuable and most misunderstood benefits in federal retirement. For a 30-year employee it can be $1,000 to $1,500 a month or more. But many federal employees who expect it discover too late that they do not qualify, or that part-time work after retirement wipes it out. This guide explains who qualifies, how it is calculated, how the earnings test works in 2026, and the mistakes to avoid. We use a hypothetical composite household, Sam and Dan, to keep the numbers concrete; they are not clients.
What is the FERS Special Retirement Supplement?
The supplement bridges the gap between a FERS retirement before 62 and Social Security eligibility at 62. Because FERS pensions are smaller than the old CSRS pensions, the supplement replaces the Social Security portion of your retirement income during those early years. Think of it as a temporary, government-paid stand-in for Social Security.
Four characteristics matter:
- Temporary. Paid only until the month before you turn 62.
- Approximate. Roughly the Social Security you earned from your federal service alone.
- Subject to an earnings test. Wages and self-employment income above the annual limit reduce it.
- Not automatic. Only certain retirement types qualify, and OPM computes it as part of your retirement application.
Who qualifies for the FERS supplement?
| Retirement type | Requirement | Supplement? |
|---|---|---|
| Immediate, unreduced at MRA | Minimum Retirement Age (55 to 57 by birth year) with 30+ years | Yes, from the first annuity payment |
| Immediate at 60 | Age 60 with 20+ years | Yes, until 62 |
| Special provisions | Law enforcement, firefighter, air traffic controller, CBP officer: age 50 with 20 years, or any age with 25 | Yes, immediately; earnings test does not apply until MRA |
| VERA (early-out) before MRA | Age 50 with 20 years, or any age with 25 | Yes, but not until you reach MRA |
| MRA+10 (reduced annuity) | MRA with 10 to 29 years | No |
| Deferred or disability retirement | Left service, or retired on disability | No |
The most common path is MRA with 30 years. Sam, in our composite, is a program director at NIH retiring at 57 with 31 years of service, which qualifies.
How is the FERS supplement calculated?
OPM estimates what your Social Security benefit at 62 would be if your only earnings were your federal service, then prorates it by your FERS service:
(Years of FERS civilian service ÷ 40) × estimated Social Security benefit at 62
Illustrative example, Sam: 30 full years of FERS service (military service bought back does not count toward this fraction) and an OPM-estimated age-62 Social Security benefit of $2,000 a month.
- (30 ÷ 40) × $2,000 = $1,500 a month, or $18,000 a year, until the month before he turns 62.
Two things people miss: the supplement is not increased by cost-of-living adjustments, so it loses purchasing power over a five-year bridge, and it is taxable as ordinary income, federal and Maryland.
What is the FERS supplement earnings test for 2026?
This is where retirees get caught. The supplement is subject to the same earnings test Social Security applies before full retirement age. For 2026 the annual limit is $24,480. Earn more than that from wages or self-employment, and OPM reduces the supplement by $1 for every $2 above the limit.
| Part-time wages after retirement | Over the $24,480 limit by | Annual supplement reduction | Sam's $18,000 supplement becomes |
|---|---|---|---|
| $20,000 | $0 | $0 | $18,000 |
| $40,000 | $15,520 | $7,760 | $10,240 |
| $60,480 | $36,000 | $18,000 | $0 |
| Counts | Does not count |
|---|---|
| Wages from any employer, including federal reemployment | Your FERS annuity and the supplement itself |
| Net self-employment income | TSP withdrawals and other pensions |
| Bonuses and severance treated as wages | Interest, dividends, capital gains, rental income (unless self-employment) |
| Social Security benefits |
Three mechanics to know:
- OPM checks once a year. Each spring OPM sends an Annuity Supplement Earnings Report asking for the prior year's earnings. The reduction begins the following July and runs for twelve months.
- Reductions are permanent. Unlike the Social Security earnings test, which credits withheld benefits back later, money lost to the FERS earnings test does not come back.
- The year you retire counts. Earnings after your retirement date in that first year are tested; your federal salary before retirement is not.
When does the supplement start and end?
- Retire at MRA or later: it starts with your first annuity payment.
- Retire under VERA before MRA: your annuity starts immediately, but the supplement waits until you reach MRA. That can be a gap of several years.
- It ends at 62 for everyone, regardless of when you claim Social Security. Delaying Social Security to 67 or 70 for a larger benefit does not extend the supplement.
Special provisions retirees: what changes
Law enforcement officers, firefighters, air traffic controllers, and Customs and Border Protection officers retire earlier and get two advantages. The supplement starts immediately at retirement, even at 50. And the earnings test does not apply until they reach their regular FERS Minimum Retirement Age; until then they can earn any amount without a reduction. Once they reach MRA the normal test applies, and the supplement still ends at 62.
VERA and the supplement
If your agency offers Voluntary Early Retirement Authority, the timing matters.
- VERA before MRA: pension starts now, supplement starts at MRA. Plan for an income gap of one to seven years.
- VERA at or after MRA: pension and supplement both start immediately, and the supplement runs to 62.
When the offer allows any flexibility, retiring at MRA rather than a year or two before it can be worth tens of thousands of dollars of supplement.
Planning the bridge years
For Sam and Dan the supplement is one of three bridge-year income sources: Sam's FERS annuity, the supplement, and modest TSP withdrawals, while Dan keeps working until 62. Three planning points:
- Decide on part-time work with the earnings test in front of you. Consulting for $40,000 in this illustration costs $7,760 of supplement, so the real after-tax value of that work is lower than it looks. Sometimes the answer is to earn under the limit, sometimes to earn well above it and treat the supplement as gone.
- Roth conversions usually wait until 62. The supplement adds taxable income before 62; once it ends and before Social Security and required distributions begin, a lower-income window often opens. That is the logic behind TSP Roth in-plan conversions after 62.
- Model the whole picture. The supplement is a five-year number inside a thirty-year plan. Our guides to how much you need to retire as a federal employee, when to claim Social Security, and Medicare Part B with FEHB at 65 cover the next decisions, and the five biggest federal retirement mistakes covers the ones to avoid on the way.
If you want your bridge years modeled with the supplement, TSP, and your spouse's income together, book a call. More guides are on our hub for federal employees.
FAQ: the FERS supplement
Who qualifies for the FERS supplement?
FERS employees who retire on an immediate, unreduced annuity: at your Minimum Retirement Age with 30 years, at 60 with 20 years, or under special provisions for law enforcement, firefighters, and air traffic controllers. VERA retirees qualify once they reach MRA. MRA+10, deferred, and disability retirees do not receive it.
What is the FERS supplement earnings limit for 2026?
The 2026 limit is $24,480 of wages or net self-employment income, the same exempt amount Social Security uses before full retirement age. Above that, OPM reduces the supplement by $1 for every $2 earned. The reduction is applied after OPM's annual earnings survey and is permanent.
Does TSP or pension income count toward the earnings test?
No. Only wages and net self-employment income count. Your FERS annuity, the supplement itself, TSP withdrawals, other pensions, Social Security, and investment income such as interest, dividends, capital gains, and rent are all excluded. Federal reemployment wages do count.
Does the FERS supplement get a cost-of-living adjustment?
No. The supplement is fixed at the amount OPM computes when you retire and is not increased by COLAs, unlike your FERS annuity after age 62. It is also taxable as ordinary income. Over a five-year bridge that fixed amount loses purchasing power, so budget for it.
What happens to the supplement if I take VERA?
If you take early retirement before your Minimum Retirement Age, your annuity begins immediately but the supplement does not start until you reach MRA, then runs to 62. If you take VERA at or after MRA, both start immediately. Special provisions retirees receive it right away either way.
