FERS Annuity Supplement: What It Is and What's Changing in 2028
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. And under the One Big Beautiful Bill Act (P.L. 119-21), it is being eliminated for most new retirees starting in 2028.
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.
OBBBA §90001: Elimination Effective January 2028
Enacted law: Section 90001 of P.L. 119-21 (the One Big Beautiful Bill Act, signed July 4, 2025) eliminates the FERS annuity supplement effective January 1, 2028, for individuals not yet entitled to it before that date.
Who is affected: FERS employees who retire on or after January 1, 2028 and were not already entitled to the supplement before that date. If you retire before January 1, 2028 and are already receiving (or entitled to) the supplement, you keep it.
Who is exempt: Law enforcement officers and related personnel who are separated under mandatory retirement provisions (generally age 57 for LEOs, age 56 for air traffic controllers) or who qualify for immediate retirement under special provisions (age 50 with 20 years, or any age with 25 years). Source: CRS In Focus IF13020 (June 2025).
What Was Removed (Not Enacted)
The original HOGR committee print also proposed increasing FERS contributions to 4.4% for all tiers (Section 90001 of that earlier version) and changing from high-3 to high-5 (Section 90003). Both provisions were removed before H.R. 1 passed the House on May 22, 2025. Only the annuity supplement elimination survived into the enacted law. Source: CRS IF12996, IF13020.
What This Means for Your Retirement Planning
If you are planning to retire before age 62 and your retirement date is on or after January 1, 2028, you may lose the supplement entirely (unless you qualify under the LEO/mandatory retirement exception). This could represent a loss of $1,000–$2,000 per month in bridge income between retirement and age 62. Employees approaching MRA+30 eligibility should carefully evaluate their timeline.
The supplement does not affect current take-home pay—it is a retirement benefit, not a paycheck deduction. However, its elimination changes the calculus of when to retire, which many federal employees are actively reconsidering.

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 ($23,400 in 2025; 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 Around the 2028 Elimination
For employees approaching retirement eligibility, the January 1, 2028 deadline creates urgency. Here are key planning considerations:
If you will be eligible to retire with an unreduced annuity before January 1, 2028: You may want to retire before the deadline to lock in supplement eligibility. Even if you plan to work longer, establishing entitlement before 2028 preserves your supplement rights.
If you will not be eligible until after January 1, 2028: Factor the loss of the supplement into your retirement planning. For a typical employee, this could mean $1,000-$2,000 per month less in income between retirement and age 62. You may need to increase TSP savings, plan to work longer, or adjust your retirement budget.
If you are a LEO or special provision employee: Review whether your specific retirement category qualifies for the exemption under §90001. The exemption covers both mandatory retirement separations and immediate retirement under special provisions (age 50 + 20 years, or any age + 25 years).
Legislative Uncertainty
While the elimination is enacted law (P.L. 119-21), future Congresses could modify or repeal this provision before January 2028. Federal employee unions (AFGE, NARFE) have actively advocated for repeal of §90001. However, given the $10 billion CBO cost estimate for the supplement over 10 years, repeal faces significant fiscal obstacles. Employees should plan as if the elimination will proceed as enacted while monitoring legislative developments.
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). Its elimination creates a meaningful gap. 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. Without the supplement, that employee would need to replace $1,000-$1,250 per month from other sources (TSP withdrawals, savings, or part-time employment) until reaching age 62.
Financial advisors commonly recommend building additional savings to bridge this gap. Increasing TSP contributions by 3-5% in the years before retirement can help offset the supplement loss. Some employees are also exploring phased retirement options, which allow reduced work schedules while drawing a partial annuity, as an alternative to full retirement before 62.
