FERS Annuity Supplement: What It Is, Eligibility & Earnings Test
The FERS annuity supplement—also called the Special Retirement Supplement (SRS)—is a benefit paid to eligible FERS employees who retire before age 62. It acts as a bridge payment until Social Security benefits become available. Although the House-passed version of the One Big Beautiful Bill Act proposed eliminating the supplement, that provision was removed by the Senate before final passage. The supplement remains in effect under current law.
What Is the Annuity Supplement?
The FERS annuity supplement approximates the Social Security benefit you earned during your years of federal service. It is authorized by 5 U.S.C. §8421 and paid monthly from the day you retire until the month you turn 62, regardless of whether you actually apply for Social Security at that point.
Who qualifies (current law): FERS employees who retire with an immediate, unreduced annuity before age 62. This typically includes: employees retiring at their Minimum Retirement Age (MRA) with 30+ years of service, employees age 60+ with 20+ years, and LEOs/firefighters/air traffic controllers retiring under special provisions.
How It Is Calculated
The supplement estimates what your Social Security benefit would be at age 62, then prorates it based on how much of your career was under FERS. The formula:
Estimated SS benefit at 62 × (Years of FERS service ÷ 40)
For example: if your estimated Social Security benefit at 62 is $2,000/month and you have 30 years of FERS service, the supplement would be approximately $2,000 × (30/40) = $1,500/month. CBO estimates the average supplement is approximately $18,000 per year for affected annuitants.
Proposed Elimination (Not Enacted)
Still in effect: The FERS annuity supplement remains available under current law. The House-passed version of the One Big Beautiful Bill Act (H.R. 1) included a provision to eliminate the supplement for new retirees, but the Senate removed this provision before final passage. P.L. 119-21 as signed does not amend 5 U.S.C. §8421.
What was proposed: The House version of H.R. 1 included language that would have eliminated the FERS annuity supplement for individuals not yet entitled to it, with a LEO exemption for certain special-provision employees. This provision, along with other proposed federal employee benefit changes (increasing FERS contributions to 4.4% and changing the high-3 to high-5 calculation), was removed during Senate consideration.
Current status: Because the elimination provision was removed before enactment, all existing eligibility rules for the FERS annuity supplement remain unchanged. Eligible FERS employees who retire with an immediate, unreduced annuity before age 62 continue to receive the supplement under 5 U.S.C. §8421.
What This Means for Your Retirement Planning
Because the proposed elimination was not enacted, the annuity supplement remains part of your retirement benefits if you qualify. For eligible employees planning to retire before age 62, the supplement can represent a significant portion of pre-62 income—typically $1,000–$2,000 per month depending on your salary and years of service.
The supplement does not affect current take-home pay—it is a retirement benefit, not a paycheck deduction. However, future legislative proposals could revisit changes to the supplement, so it is worth monitoring congressional activity as part of long-term retirement planning.

Who Currently Qualifies for the Supplement
Under current law (5 U.S.C. §8421), you qualify for the FERS annuity supplement if you retire with an immediate, unreduced FERS annuity before age 62. Specifically:
Voluntary retirement at MRA + 30: If you reach your Minimum Retirement Age (55-57 depending on birth year) with 30 or more years of creditable service, you qualify for an immediate annuity and the supplement.
Voluntary retirement at 60 + 20: If you are at least 60 with 20 or more years of service, you qualify.
Special provision employees: Law enforcement officers, firefighters, and air traffic controllers who retire under their mandatory or special provisions also qualify.
Discontinued service / Early out: Employees who retire under agency-offered early retirement (discontinued service or early-out) also qualify, provided they meet the age and service requirements.
You do NOT qualify if you retire at MRA + 10 (with the 5% per year age reduction) or if you voluntarily separate before meeting unreduced retirement eligibility.
The Earnings Test
The FERS annuity supplement is subject to an earnings test similar to Social Security's. If you work after retiring and earn above the Social Security annual exempt amount ($24,480 in 2026; adjusted annually), your supplement is reduced by $1 for every $2 of earnings above the threshold. This means retirees who take significant post-retirement employment may see their supplement reduced or eliminated entirely.
Planning With the Supplement
Since the supplement remains in effect, eligible FERS employees can continue to factor it into their retirement planning. Key considerations:
Know your eligibility: Confirm that you will retire with an immediate, unreduced FERS annuity before age 62. The supplement is only available under those conditions.
Account for the earnings test: If you plan to work after retiring, remember that earnings above the annual exempt amount will reduce your supplement. Factor this into any post-retirement employment plans.
Monitor future legislation: Although the proposed elimination was not enacted this time, similar proposals may be reintroduced in future legislation. Stay informed about congressional activity affecting federal retirement benefits.
Legislative Background
The FERS annuity supplement has been a target of cost-saving proposals in multiple budget cycles. The House-passed version of the One Big Beautiful Bill Act (H.R. 1, 2025) included a provision to eliminate the supplement, but this was removed by the Senate before P.L. 119-21 was signed into law. Federal employee organizations (AFGE, NARFE) successfully advocated against the provision. Similar proposals could resurface in future legislation, as CBO has estimated the supplement costs approximately $10 billion over 10 years.
The Supplement and Your Retirement Budget
For employees planning to retire before 62, the supplement can represent 15-25% of total pre-62 retirement income (pension plus supplement). Consider a typical scenario: a GS-13 retiring at 57 with 32 years of service and a $120,000 high-3 might receive approximately $38,400 in annual pension and $12,000-$15,000 in annual supplement. This bridge income helps cover the gap between retirement and age 62 when Social Security benefits become available.
Even with the supplement available, financial advisors recommend diversifying retirement income sources. Maximizing TSP contributions, considering phased retirement options (which allow reduced work schedules while drawing a partial annuity), and planning for the earnings test are all important steps for pre-62 retirees.
