FERS Supplement 2026: How It Works, Earnings Limit, and FIRE Planning Guide

The FERS Annuity Supplement is one of the most valuable — and most misunderstood — pieces of the federal employee retirement package. It pays you a Social Security-equivalent monthly income from the day you retire until you turn 62, bridging the gap between early retirement and Social Security eligibility.

In 2026, two things drove a surge in FERS Supplement Google searches: (1) the OBBB scare — a provision in H.R. 1 would have eliminated the supplement starting 2028, causing widespread panic among federal employees planning to retire in their 50s; and (2) the annual earnings limit update to $24,480 for 2026. This guide covers both, plus the complete FIRE planning math.

Quick answer on the OBBB: The Senate removed the FERS Supplement elimination provision before the bill was signed. The supplement is fully intact under current law as of July 2026.

What Is the FERS Supplement?

The FERS Annuity Supplement (also called the Special Retirement Supplement or SRS) is a monthly payment that FERS retirees receive from OPM from the date of retirement until age 62.

Its purpose: to bridge the gap between federal retirement and Social Security eligibility at 62. Unlike Social Security, which most workers can't access until 62 at the earliest, FERS employees who meet the age and service requirements can retire in their mid-to-late 50s — and the supplement fills the income gap.

Key facts:

• Paid by OPM (Office of Personnel Management), not Social Security
• Designed to approximate what your Social Security benefit would be at 62
• Stops the month you turn 62 — regardless of whether you claim Social Security
• Subject to an earnings test (like Social Security before full retirement age)
• Taxable as ordinary income (federal and most states)

---

Who Qualifies?

You receive the FERS Supplement if you:

Who does NOT qualify:

• Employees who retire under Voluntary Early Retirement Authority (VERA) before age 60 (VERA at 60+ with 20 years does qualify)
• Disability retirees
• Deferred retirees (left federal service before MRA and are waiting to collect pension)
• CSRS employees (CSRS has Social Security coverage through a different mechanism)

What Is Your MRA?

Your Minimum Retirement Age depends on your year of birth:

Most federal employees born after 1970 (the majority of the current federal workforce) have an MRA of 57.

How to Calculate Your FERS Supplement

The formula is straightforward:

FERS Supplement = (Estimated Social Security benefit at 62 ÷ 40) × Years of FERS service

The "÷ 40" in the formula represents 40 years of Social Security-covered work — the approximate full career. Your supplement is prorated based on how many of those 40 years you spent in FERS service.

Step 1: Find Your Social Security Estimate at Age 62

Log into ssa.gov/myaccount and view your Social Security Statement. Look for the "If you stop working now" estimate at age 62 — this is the figure OPM uses in the formula.

Note: This figure changes over time as OPM does a final calculation at retirement using your actual SS earnings record. But the Statement estimate is close enough for FIRE planning.

Step 2: Apply the Formula

Example 1 — 30 years of service, $2,400/month SS estimate:

• ($2,400 ÷ 40) × 30 = $1,800/month
• Annual supplement: $21,600/year

Example 2 — 25 years of service, $2,200/month SS estimate:

• ($2,200 ÷ 40) × 25 = $1,375/month
• Annual supplement: $16,500/year

Example 3 — 20 years of service, $2,000/month SS estimate:

• ($2,000 ÷ 40) × 20 = $1,000/month
• Annual supplement: $12,000/year

The 2026 Earnings Limit: $24,480

The FERS Supplement has an earnings test — if you continue working after retirement, your supplement is reduced if your earned income exceeds the annual limit.

2026 earnings limit: $24,480

Reduction formula: For every $2 you earn over the limit, your supplement is reduced by $1.

What Counts as "Earnings"?

Counts (reduces supplement):

• Wages from a job (W-2 income)
• Net self-employment income (Schedule C/SE)

Does NOT count:

• FERS pension payments
• TSP withdrawals
• Social Security benefits
• Investment income (dividends, capital gains, interest)
• Rental income
• Roth IRA withdrawals
• Inheritance or gifts

Earnings Limit Impact Examples

Key insight for FIRE planning: The earnings limit primarily affects federal retirees who pursue Barista FIRE — working part-time after leaving federal service. If your post-retirement income is from investments, Roth withdrawals, or rental income (very common FIRE income sources), the earnings test does not apply.

FERS Supplement FIRE Planning: The Complete Bridge Strategy

For FIRE-minded federal employees, the FERS Supplement is a core pillar of the income bridge from federal retirement to either Social Security at 62 or full portfolio independence.

The Federal FIRE Income Bridge (Ages 57–67)

A typical FIRE-optimized federal employee might retire at MRA (57 for those born 1970 or later) with 30 years of service and structure their income like this:

The FERS Supplement FIRE Number Reduction

Using the 4% rule: every $1 of annual supplement income reduces your required portfolio by $25.

A federal employee receiving $1,800/month in supplement income needs $540,000 less in portfolio to sustain the same lifestyle vs. a private-sector peer with no pension/supplement support. This is the mathematical advantage of federal FIRE.

Key Tactical Decision: Work to 30 Years or Exit at 20?

Watch out: MRA+10 retirements — retiring at MRA with 10–29 years of service — do not include the FERS Supplement. Many federal employees discover this too late. If you're planning an MRA+10 exit, you need a larger brokerage bridge to compensate for the missing supplement income.

---

FERS Supplement vs. Social Security: Key Differences

The most important difference: the FERS Supplement has no COLA. Social Security adjusts for inflation annually. A $1,800/month supplement in 2026 is still $1,800/month in 2033 — its real purchasing power declines over time. Plan your budget with inflation in mind: at 3% inflation, your supplement loses roughly 20% of its real value over 7 years.

---

FERS Supplement and Taxes

The FERS Supplement is taxable as ordinary income at the federal level. It is reported on your OPM 1099-R (the same form as your pension) and is subject to federal income tax withholding.

State taxes: Most states that tax pension income also tax the FERS Supplement. A few states (Pennsylvania, New York for government pensions, Illinois) exempt federal retirement income — check your state's rules.

Tax Planning Opportunity: Filling the 0% and 12% Brackets

In early retirement, FERS pensioners on a supplement often have room in the 0% and 12% federal brackets for Roth conversions. Here's why:

If your FERS pension + FERS supplement = $50,000/year, and the standard deduction is $15,000 (single) or $30,000 (MFJ), your taxable income is $35,000 (single) or $20,000 (MFJ). The 12% bracket runs to $47,150 (single) or $94,300 (MFJ) in taxable income — leaving significant room for Roth conversions at 12% before hitting 22%.

Use the Roth Conversion Ladder guide to model how to fill these brackets strategically during the supplement years.

Was the FERS Supplement Eliminated? (OBBB 2026)

In early-mid 2026, a provision in the One Big Beautiful Bill (H.R. 1) would have eliminated the FERS Annuity Supplement for employees retiring after December 31, 2027. This caused widespread alarm among federal employees — particularly those with 20–29 years of service who hadn't yet reached MRA.

What happened:

1. The House passed H.R. 1 with the FERS Supplement elimination included
2. The provision was scored as a savings measure — eliminating the supplement would reduce long-term federal retirement costs
3. When the bill moved to the Senate, the FERS Supplement elimination was removed — it violated the Byrd Rule, which prohibits provisions in budget reconciliation bills that are "extraneous" to the budget (have primarily non-budgetary effects on federal employee benefits)
4. The final bill signed into law does not include any change to the FERS Supplement

Current status as of July 2026: The FERS Annuity Supplement is fully intact and operates exactly as it did before H.R. 1. No changes to the supplement are currently in law or in pending legislation.

What this means for your FIRE planning: You can plan on the FERS Supplement as a reliable income source, subject to the standard earnings test and the age-62 cutoff. The elimination risk has been removed for now — though long-term legislative risk always exists for any government benefit program.

Step-by-Step: Building Your Federal FIRE Bridge

Here is a concrete action plan for federal employees targeting FIRE in their mid-to-late 50s:

Step 1: Calculate Your Pension Income

Use OPM's FERS pension formula: 1% × years of service × High-3 average salary (or 1.1% if retiring at 62+ with 20+ years).

Example: 30 years × 1% × $90,000 High-3 = $27,000/year pension.

Step 2: Calculate Your FERS Supplement

Log into ssa.gov/myaccount → get your SS estimate at 62 → apply the formula: (SS at 62 ÷ 40) × years of service.

Example: ($2,400 ÷ 40) × 30 = $1,800/month = $21,600/year.

Step 3: Calculate Your Federal FIRE Number

Federal FIRE Number = (Annual spending − Pension − Supplement) ÷ 0.04

Example: ($80,000 spending − $27,000 pension − $21,600 supplement) ÷ 0.04 = ($31,400) ÷ 0.04 = $785,000

Without the pension and supplement, this household would need $2,000,000 at 4%. The federal package reduces the required portfolio by $1,215,000.

Use the FIRE Calculator to model your specific numbers with pension income inputs.

Step 4: Build Your Bridge Assets

You need enough in taxable brokerage + Roth IRA contributions to bridge:

• From retirement age to TSP access (if before 55) or to cover any supplemental spending
• The 5-year Roth conversion wait (start conversions immediately at retirement)
• Any healthcare gap before Medicare at 65 (see Health Insurance Early Retirement 2026)

Rule of thumb: accumulate 2–3 years of spending in taxable/accessible accounts before retiring, even with a full pension + supplement.

Step 5: Optimize the Supplement Earnings Limit

If you plan to do any consulting, part-time work, or side projects after retirement:

• Stay under $24,480 in earned income to preserve your full supplement
• Or use investment income (which doesn't count) to supplement lifestyle while keeping wages below the threshold
• Consider structuring business income as passive rental or investment returns where possible

Step 6: Model the Age-62 Transition

When the supplement stops at 62, your income drops by the supplement amount. Plan for this:

• Delay TSP withdrawals until 62+ when supplement stops to maintain similar total income
• Evaluate whether to claim Social Security at 62 (reduced benefit) or delay to maximize lifetime income
• Use the Retirement Calculator to model Social Security timing decisions

FERS Supplement Calculator

While OPM does the official calculation at retirement, you can estimate your supplement using these inputs:

Your FERS Supplement Estimate:

1. Go to ssa.gov/myaccount and note your estimated Social Security benefit at age 62
2. Count your years of FERS civilian service (shown on your SF-50)
3. Apply the formula: (SS at 62 ÷ 40) × FERS service years

Or use our FIRE Calculator — enter your pension + supplement combined as "pension income" to see your adjusted FIRE number.

Key Takeaways

• The FERS Annuity Supplement bridges the gap between federal retirement and Social Security at 62 — approximating your SS benefit prorated for FERS service years
• The 2026 earnings limit is $24,480 — investment income, rental income, and pension income do NOT count toward this limit; only wages and self-employment income do
• The supplement was NOT eliminated by the One Big Beautiful Bill — the Senate removed that provision; it remains fully intact
• MRA+10 retirees do not receive the supplement — this is the most common planning mistake federal FIRE employees make
• Every $1,000/month in supplement income reduces your required FIRE portfolio by $300,000 (at the 4% rule)
• Build a Roth conversion strategy during the supplement years using the bracket room below your supplement + pension income
