Social Security and Divorce for Federal Employees: The 10-Year Rule and WEP/GPO Repeal

The WEP and GPO Repeal Changed Everything

For decades, federal employees under CSRS (and some dual-status FERS employees) faced two provisions that dramatically reduced or eliminated their Social Security benefits and their former spouses' access to them:

• The Windfall Elimination Provision (WEP) reduced a federal retiree's own Social Security benefit by adjusting the primary insurance amount formula — dropping the first bend-point replacement rate from 90% to as low as 40%
• The Government Pension Offset (GPO) reduced Social Security spousal and survivor benefits by two-thirds of the government pension amount, often zeroing them out entirely

The Social Security Fairness Act, signed into law on January 5, 2025, repealed both provisions retroactively to January 2024. The practical effect: former spouses of federal employees who were previously told they'd receive little or nothing from Social Security can now claim full, unreduced benefits.

This is the most significant change to the intersection of federal retirement and divorce law in a generation. Nearly all divorce guidance published before 2025 that discusses WEP or GPO is now incorrect.

The 10-Year Marriage Rule Still Applies

Social Security's basic eligibility rules for divorced spouses remain unchanged:

• The marriage must have lasted at least 10 years
• The former spouse must be at least 62 years old
• The former spouse must be currently unmarried (or remarried after age 60 for survivor benefits)
• The former spouse must not be entitled to a higher Social Security benefit based on their own work record

If these conditions are met, the former spouse can receive up to 50% of the worker's primary insurance amount as a spousal benefit (while the worker is alive), or up to 100% as a survivor benefit (after the worker dies).

The repeal of WEP and GPO means these benefits are now calculated without any reduction for a government pension. A CSRS retiree's former spouse who was previously told the GPO would reduce their Social Security spousal benefit to zero is now eligible for the full amount.

Who Needs to Take Action

Former spouses already receiving reduced benefits: SSA automatically adjusted monthly payments starting February 25, 2025, and issued retroactive lump-sum payments back to January 2024. No application was needed for this group.

Former spouses who never applied because of the WEP or GPO: This is the critical group. If you assumed the GPO would zero out your benefit and never filed a Social Security application, your benefits are not retroactive to January 2024. Under standard SSA rules, retroactive payments for retirement and spousal benefits are limited to a maximum of six months before the month you file.

Every month of delay past that six-month lookback window is lost permanently. Former spouses of CSRS employees who have not yet applied should file immediately.

Former spouses planning future claims: If you're approaching age 62 and your marriage to a federal employee lasted at least 10 years, the WEP/GPO repeal means Social Security benefits that previously weren't worth claiming are now available in full. Factor these benefits into your retirement income projections.

How This Interacts With FERS and CSRS Divorce Benefits

The Social Security benefit a former spouse receives is completely separate from the pension division under a COAP or the TSP division under an RBCO. Social Security benefits are not divided by court order — they're individual entitlements based on the marriage duration and each person's earnings record.

This means a former spouse can potentially receive three separate income streams from a federal divorce:

1. Their share of the FERS or CSRS pension — as divided by the COAP
2. Their share of the TSP — as divided by the RBCO
3. Social Security spousal or survivor benefits — based on the 10-year marriage rule, now unreduced

For CSRS employees specifically, the repeal is transformative. CSRS retirees paid nothing into Social Security during their federal careers, and the GPO previously wiped out most spousal and survivor benefits. With the repeal, former spouses of CSRS employees can now claim full Social Security benefits — in addition to whatever pension share the COAP awards.

The Six-Month Filing Trap

This bears repeating because the financial stakes are high: if you're a former spouse of a federal employee, you're eligible for Social Security benefits, and you haven't yet filed, the six-month retroactive limit means you're losing money every month you wait.

SSA's standard retroactive payment window works as follows:

• You file your application in August 2026
• SSA can pay retroactive benefits back to February 2026 (six months)
• Any months between January 2024 (when the repeal took effect) and January 2026 are permanently lost

For a spousal benefit of $1,200 per month, a 12-month delay in filing costs $14,400 in lost retroactive payments. The former spouse still receives future benefits going forward, but the missed months are gone.

The filing process is through SSA directly — not through OPM, not through the TSP, and not through the former spouse's state court. Applications can be submitted online at ssa.gov or at a local Social Security office.
