Military Buyback After WEP and GPO Repeal: What the Social Security Fairness Act Changes

WEP and GPO Are Gone — What Does That Mean for Military Buyback?

The Social Security Fairness Act (P.L. 118-273), signed into law on January 5, 2025, completely repealed two provisions that had reduced Social Security benefits for federal retirees for decades: the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO). The repeal is retroactive for benefits payable after December 2023, and SSA completed over 3.1 million retroactive payments totaling $17 billion by July 2025.

For federal employees weighing whether to buy back military time, the repeal changes the calculus — but not in the direction you might expect. The military buyback decision is actually simpler now, and the case for completing the deposit is stronger than it was before the repeal.

How WEP Used to Complicate the Buyback Decision

Before the repeal, WEP reduced Social Security benefits for people who received a pension from employment not covered by Social Security — most notably CSRS employees and some FERS transferees who had CSRS service. The reduction was based on a modified formula that lowered the first-bend-point factor in the Social Security benefit calculation.

Some employees factored WEP into their military buyback analysis like this: "If I buy back my military time and increase my CSRS pension, WEP will reduce my Social Security benefit. The higher pension might trigger a bigger WEP reduction, partially offsetting the annuity gain."

That logic no longer applies. With WEP repealed, your Social Security benefit is calculated using the standard formula regardless of your CSRS or FERS pension amount. Increasing your annuity through military buyback has zero effect on your Social Security benefit.

How GPO Used to Affect Spousal Calculations

GPO reduced Social Security spousal and survivor benefits by two-thirds of the government pension amount. A CSRS retiree receiving a $30,000 annuity would have their Social Security spousal benefit reduced by $20,000 — often eliminating the spousal benefit entirely.

Some employees and their spouses worried that increasing the CSRS annuity through military buyback would increase the GPO reduction, wiping out more of the spousal Social Security benefit.

With GPO repealed, this concern is eliminated. A spouse receiving Social Security benefits based on the federal employee's record (or their own) will receive the full amount regardless of the size of the government pension. Military buyback increases the annuity without any offsetting Social Security reduction for either spouse.

The Simpler Math After the Repeal

With WEP and GPO off the table, the military buyback financial analysis reduces to a clean comparison:

Cost: The deposit amount (3% of military basic pay for FERS, 7% for CSRS) plus any accrued interest.

Benefit: The annual annuity increase from the additional years of credited service, received for every year of retirement.

There is no longer a secondary effect on Social Security to model. The return on the deposit is purely a function of the annuity formula: your high-3 salary, total creditable service years, and the applicable multiplier (1.0% or 1.1% for FERS, tiered for CSRS).

For most employees, this makes the decision clearer. A FERS employee with 4 years of military service, a $95,000 high-3, and a deposit cost of $5,000 gains roughly $3,800-$4,180 per year in additional annuity. The deposit pays for itself within 15-18 months of retirement, and every year after that is pure gain. No Social Security offset complicates the arithmetic.

CSRS Employees: The Age 62 Deposit Still Matters

For CSRS employees who first entered civilian service after September 30, 1982, the post-1956 military service deposit carries an additional rule: if you do not complete the deposit, OPM reduces your annuity at age 62 to account for the Social Security benefit attributable to your military service.

The repeal of WEP does not change this reduction. The age-62 CSRS reduction is a separate provision under 5 U.S.C. § 8332(j) — it is built into the civil service retirement statute, not the Social Security Act. It operates independently of WEP and GPO.

The practical impact: CSRS employees with post-1956 military service still need to complete the deposit to avoid the age-62 annuity reduction. The WEP/GPO repeal does not remove this requirement. If anything, it makes the deposit more valuable because the full Social Security benefit is now preserved alongside the unreduced CSRS annuity.

Previously Offset Beneficiaries Should Check Their Records

If you are already retired and your Social Security benefits were previously reduced by WEP or GPO, SSA has processed automatic adjustments and retroactive payments back to January 2024. You do not need to file a new claim for the adjustment if you were already receiving benefits.

However, if you never applied for Social Security benefits because you believed WEP or GPO would eliminate them entirely, you must file a new claim. The adjustment is not automatic for people who never applied — SSA cannot adjust a benefit that was never established.

This applies to both current and former federal employees, including those who completed or did not complete a military buyback. The repeal restores full Social Security benefits regardless of your federal pension status.

The Bottom Line for Buyback Decisions

The Social Security Fairness Act removed the last remaining argument against military buyback for employees who were concerned about cross-system benefit reductions. The deposit increases your annuity, the annuity increase does not reduce your Social Security, and your spouse's Social Security benefits are fully preserved regardless of your pension amount.

The Military Buyback Guide for Federal Employees includes updated worksheets that reflect the post-repeal landscape, so every annuity calculation accounts for the current statutory framework — no stale WEP/GPO adjustments baked in.
