The Special Retirement Supplement (SRS)
The Special Retirement Supplement (SRS) is a monthly bridge payment for federal employees who retire before age 62. It approximates the Social Security you earned during FERS service, and OPM pays it from your retirement date until you turn 62. Only an immediate, unreduced retirement qualifies.

What the Special Retirement Supplement is
The Special Retirement Supplement, or SRS, fills a gap that FERS built into early retirement. A federal employee can retire as early as their Minimum Retirement Age, but Social Security cannot start until age 62. The SRS bridges those years, paying an estimate of your earned Social Security from your retirement date until the month you turn 62.
FERS was designed around this gap on purpose. Under the older CSRS system, the pension alone replaced most of a career employee's income, so no bridge was needed. The FERS pension is smaller because the Thrift Savings Plan (TSP) and Social Security carry part of the load.
OPM pays the supplement, not the Social Security Administration. It is part of your FERS package, calculated by OPM and paid in the same monthly payment as your pension. You do not file a separate claim for it.
The supplement is temporary by design, and that is its defining feature. Every other pillar of FERS continues for life; the SRS is the one that ends. It stops the month you reach 62, whether or not you actually claim Social Security that year. The rest of this lesson covers who qualifies, how OPM sizes the payment, and the earnings test that can reduce it.

What is the Special Retirement Supplement?
The Special Retirement Supplement (SRS) is a monthly payment for FERS employees who retire before age 62 on an immediate, unreduced annuity. It approximates the Social Security benefit you earned through federal service. OPM pays it from your retirement date until the month you turn 62, when Social Security itself becomes available. It is sometimes called the FERS annuity supplement.
Who pays the SRS, OPM or Social Security?
OPM pays the supplement, not the Social Security Administration. It is computed and paid as part of your FERS retirement, arriving in the same monthly payment as your basic annuity. Because OPM handles it, you do not file a separate Social Security claim to receive it. Your actual Social Security benefit is a separate payment that can begin at 62 or later.
Why does FERS have a supplement at all?
FERS lets career employees retire before 62, but Social Security cannot start that early. The supplement bridges the gap so an early retiree is not left without that pillar of income. Under CSRS, the pension was large enough that no bridge was needed. FERS pairs a smaller pension with the TSP and Social Security, so the supplement fills in until Social Security can take over.
Is the SRS the same as Social Security?
No. The SRS only approximates the Social Security you earned in federal service, and OPM pays it rather than the Social Security Administration. It ends at 62, while Social Security continues for life. Your eventual Social Security benefit is based on your full earnings record, so it is usually larger than the supplement. The two are separate benefits with separate rules.
Who qualifies for the SRS
You qualify for the SRS only if you retire on an immediate, unreduced FERS annuity before age 62. In practice that means two main paths: retiring at your Minimum Retirement Age with 30 years of service, or at age 60 with 20 years. Several common retirements do not qualify.
The supplement rewards reaching full, unreduced eligibility before 62. Three groups are left out, and the reasons matter.
Special-provision employees follow their own timeline. Law enforcement officers, firefighters, and air traffic controllers can retire earlier and start the supplement right away. Their earnings test does not begin until they reach their MRA, unlike standard retirees.
Early-out offers add one more case. Employees who take a Voluntary Early Retirement Authority (VERA) separation can be eligible, but the supplement does not begin until they reach their MRA. If you are unsure which path applies to you, your agency benefits office can confirm before you set a retirement date.
- MRA+10 retirees: the annuity is reduced for age, so no supplement is paid.
- Deferred retirees: leaving federal service and claiming a pension later earns no SRS.
- Disability retirees: a FERS disability retirement is computed differently and carries no supplement.
Who is eligible for the FERS Special Retirement Supplement?
You are eligible if you retire on an immediate, unreduced FERS annuity before age 62. The two standard paths are your Minimum Retirement Age with 30 years of service, or age 60 with 20 years. Special-provision employees and some early-out retirees also qualify under their own rules. Retiring at 62 or older means there is no supplement, because Social Security is already available.
Does MRA+10 retirement qualify for the SRS?
No. The MRA+10 option lets you retire at your Minimum Retirement Age with 10 to 29 years of service, but the annuity is reduced for each year you are under 62. Because the annuity is reduced rather than immediate and unreduced, no supplement is paid. Retirees choosing MRA+10 should plan to bridge the years before Social Security from other income, such as the TSP.
Do deferred or disability retirees get the SRS?
No. Deferred retirees, who leave federal service and claim a pension at a later age, do not receive the supplement. Disability retirees do not receive it either, because a FERS disability annuity is computed under a separate formula. The SRS is reserved for employees who retire on an immediate, unreduced annuity before 62. Both groups can still claim their own Social Security at 62 or later.
How is the SRS different for law enforcement and firefighters?
Special-provision employees, including law enforcement officers, firefighters, and air traffic controllers, can retire earlier than other feds and begin the supplement right away. The key difference is the earnings test: for these retirees it does not apply until they reach their Minimum Retirement Age. A firefighter who retires at 52, for example, can earn wages with no supplement reduction until MRA, then the standard test begins.
How OPM calculates the SRS
OPM sizes the supplement with a simple proration. It starts from an estimate of the Social Security benefit you earned, as if you were 62 on your retirement day. Then it multiplies that estimate by your years of FERS service divided by 40.
In words, the formula is the estimated age-62 Social Security benefit times your FERS years over 40. The 40 stands for a notional full Social Security career of 40 years. OPM rounds the result down and pays it monthly.
Walk through an example. Say a federal employee named Dana retires at 60 with 30 years of FERS service, and her estimated age-62 Social Security benefit is an example $1,800 a month. OPM divides 30 by 40 to get 0.75, then multiplies: $1,800 times 0.75 is $1,350 a month. (Figures are illustrative; see our assumptions for the values the calculator uses.)
One detail trips people up. The estimate counts only your federal FERS earnings, not any private-sector Social Security you also earned. That is why the supplement is usually smaller than your eventual Social Security check. The supplement covers the federal share, and your full Social Security record catches up the rest at 62.
The supplement counts only your federal earnings. Your full Social Security record catches up the rest at 62.
How is the FERS Special Retirement Supplement calculated?
OPM estimates the Social Security benefit you earned through federal service, as if you were 62 on your retirement day. It then multiplies that estimate by your total years of FERS service divided by 40, and rounds down. For example, an estimated $1,800 benefit with 30 years of service is $1,800 times 0.75, or $1,350 a month. The result is paid monthly until you turn 62.
Why is my SRS smaller than my Social Security estimate?
The supplement counts only the Social Security you earned in federal FERS service, and it prorates that by your years over 40. Any Social Security you earned from private-sector work is left out of the supplement. Your eventual Social Security benefit at 62 or later is based on your full earnings record, so it is usually larger. The supplement is a partial, federal-only bridge, not your whole benefit.
Does the SRS use my actual Social Security statement?
Not directly. OPM produces its own estimate of the benefit you earned through federal service, then applies the years-over-40 proration. Your Social Security statement at ssa.gov reflects all of your work, federal and private, so it will not match the supplement amount. Use the statement to understand your full benefit at 62, and treat the supplement as a separate, smaller, OPM-calculated figure.
Does the SRS get cost-of-living raises?
No. The supplement is never increased by a cost-of-living adjustment (COLA). The amount OPM sets at retirement stays flat until the supplement ends at 62. Because of that, inflation slowly chips away at its buying power over the bridge years. Your basic FERS pension has its own COLA rules, but those adjustments do not extend to the supplement.
The SRS earnings test, in brief
If you work after retiring, the SRS earnings test can reduce your supplement. It mirrors the Social Security earnings test. Earn more than the annual limit and OPM cuts the supplement by $1 for every $2 you go over.
The reduction is based on the prior year's earnings. Each year OPM mails an Annuity Supplement Earnings Report to non-disability retirees between their MRA and 62. You report wages and self-employment income; your pension and TSP withdrawals do not count.
The annual limit is the same exempt amount the Social Security earnings test uses, and it changes each year. We do not list the figure here because it moves annually; see our assumptions for the current value. A part-time job under the limit has no effect on the supplement.
The earnings test has a few more wrinkles, including how the first year is handled and the special-provision exemption until MRA. A dedicated Late Career lesson on the SRS earnings test covers the timing and the reporting form in detail. The short version: steady wages above the limit can shrink or even erase the supplement.
How does the SRS earnings test work?
If your wages and self-employment income exceed an annual limit, OPM reduces your supplement by $1 for every $2 over that limit. The limit is the same exempt amount the Social Security earnings test uses, and it changes each year. The reduction is based on the prior year's earnings, reported on a form OPM mails you. Earnings at or below the limit have no effect.
What income counts toward the SRS earnings test?
Only earned income counts: wages from a job and net self-employment income. Your FERS pension, the supplement itself, TSP withdrawals, investment income, and rental income do not count. That distinction matters for retirees who take a part-time job but draw most of their income from the pension and the TSP. Those passive sources never trigger a reduction, no matter how large.
Does the earnings test apply to law enforcement and firefighters?
Not right away. Special-provision retirees, including law enforcement officers, firefighters, and air traffic controllers, are exempt from the earnings test until they reach their Minimum Retirement Age. A firefighter who retires at 52 can earn wages freely until MRA, then the standard $1-for-$2 reduction begins. This exemption recognizes that these employees are required to retire earlier than other feds.
Can earnings wipe out my supplement entirely?
Yes. Because the reduction is $1 for every $2 over the limit, high enough earnings can reduce the supplement to zero for the year. A retiree who returns to substantial full-time work may receive little or no supplement until the wages stop or the supplement ends at 62. The dedicated SRS earnings-test lesson walks through the timing and how a return to work is handled.
What the SRS is not
The SRS is easy to misunderstand because it looks like Social Security. Four differences cause the most surprise at retirement. Knowing them up front keeps your income plan honest.
The missing COLA matters more than it looks. A fixed payment loses buying power every year inflation runs above zero. Over a five-year bridge that erosion is modest, but it is real, and your pension's own COLA does not backfill it.
The age-62 cliff is the trap that catches planners. Many federal retirees assume the supplement rolls into Social Security automatically. It does not: the supplement simply stops, and you decide separately when to claim Social Security, which you can delay past 62 for a larger benefit.
- No cost-of-living raises. The supplement is never increased by a COLA, so inflation slowly erodes its value.
- It is taxable. The SRS is taxed as ordinary income, like the rest of your FERS annuity.
- It ends hard at 62. The supplement stops the month you turn 62, even if you delay claiming Social Security.
- It is not your Social Security. Claiming, or not claiming, at 62 does not change the supplement; the two are separate benefits.
The supplement does not roll into Social Security. It stops at 62, and your claiming decision is a separate choice.
Does the SRS get cost-of-living adjustments?
No. OPM never applies a cost-of-living adjustment to the supplement. The monthly amount set at retirement stays flat until the supplement ends at 62. Inflation gradually reduces its buying power over the bridge years, which is worth factoring into an early-retirement budget. The basic FERS pension follows its own COLA rules, but those do not extend to the supplement.
Is the Special Retirement Supplement taxable?
Yes. The supplement is taxed as ordinary income, the same way the rest of your FERS annuity is taxed. It is not treated under the special rules that can make a portion of Social Security tax-free. Plan for the supplement as fully taxable federal income in the years you receive it. Your state may tax it differently, so confirm your state's treatment of federal annuities.
Does the SRS continue past age 62?
No. The supplement stops the month you reach 62, whether or not you file for Social Security that month. It is a bridge, not a permanent benefit. At 62 you choose when to claim Social Security, and you can delay past 62 to increase that benefit. If you delay, you bridge the gap from other income, because the supplement will already have ended.
Does the SRS reduce my future Social Security benefit?
No. The supplement is a separate OPM payment and does not subtract from your Social Security. Your Social Security benefit is based on your full earnings record and is unaffected by the supplement you received before 62. Receiving the SRS does not use up or reduce any part of your Social Security. The two benefits are calculated and paid independently.
How the SRS fits your retirement plan
Think of the SRS as a temporary pillar that hands off to Social Security at 62. In the early retirement years it sits beside your pension and any TSP withdrawals. At 62 it stops, and the Social Security claiming decision takes over.
Your income statement changes shape at 62. Before then, a typical early retiree draws the FERS pension, the SRS, and TSP withdrawals. After the supplement ends, Social Security can replace it, either right away or later if you choose to wait for a larger benefit.
The handoff is where planning pays off. The supplement ends whether or not you claim, so some retirees claim Social Security at 62 to replace it. Others bridge with TSP withdrawals and delay for a larger lifetime benefit. There is no single right answer; it depends on your other income, your health, and your spouse.
The supplement is one piece of a larger picture. To see how the SRS, your pension, Social Security, and your TSP fit together against your target, run your free readiness score. It models the bridge years and the age-62 handoff so you can stress-test the plan before you set a date.
What happens to my income when the SRS ends at 62?
The supplement stops, and Social Security becomes available to replace it. If you claim Social Security at 62, the new benefit picks up where the supplement left off, often at a higher amount because it reflects your full earnings record. If you delay, you cover the gap from the TSP or other savings until you claim. Your pension and any TSP withdrawals continue throughout.
Should I claim Social Security when my SRS stops?
That is a personal decision, not a rule. Because the supplement ends at 62 regardless, some retirees claim Social Security then to keep their income steady, while others delay for a larger lifetime benefit and bridge the gap with TSP withdrawals. The right choice depends on your other income, your health, your spouse, and your tax picture. We explain the factors rather than recommend a claiming age.
How do I know if I am on track with the supplement included?
Model your full income picture, including the supplement, the pension, the TSP, and Social Security. Our free readiness score does this for FERS retirees and shows how the bridge years compare with your target. It highlights the age-62 handoff, where many plans have a gap. Reviewing it before you set a retirement date gives you time to adjust contributions or timing.
Where can I confirm my own SRS eligibility and amount?
Your agency benefits office and OPM are the authorities for your specific case. They can confirm whether your retirement is immediate and unreduced, and estimate your supplement based on your service. The OPM types-of-retirement page lays out the eligibility rules. Use our calculator for planning, then verify the exact figures with OPM before you commit to a date.
