Social Security Fairness Act and FERS Disability Retirement

What the Social Security Fairness Act Changed

The Social Security Fairness Act (H.R. 82), signed into law on January 5, 2025, repealed two provisions that had reduced Social Security benefits for federal employees and other public-sector workers for decades: the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO).

WEP had reduced Social Security retirement benefits for workers who also received a pension from employment not covered by Social Security — primarily CSRS employees, but also some state pension recipients. GPO had reduced or eliminated Social Security spousal and survivor benefits for the same group.

The repeal is retroactive to benefits payable for January 2024 onward. SSA completed automatic adjustments and paid retroactive lump sums starting in February 2025. Implementation is finished.

What This Means for FERS Disability Annuitants

If you're a FERS disability retiree, WEP likely never applied to your Social Security benefit in the first place. FERS employees pay into Social Security throughout their careers, so their Social Security benefits were calculated using the standard formula — WEP only hit people with non-covered pension income.

Where the Fairness Act matters for FERS disability retirees:

Spousal and survivor benefits. If your spouse was a CSRS retiree or received a non-covered state pension, GPO previously reduced or eliminated the Social Security spousal or survivor benefit you might receive based on their record. That reduction is gone. If you were denied a survivor benefit because of GPO, file a new claim with SSA — restoration is not automatic for people who never applied.

Dual-career situations. If you had earlier career service under CSRS before converting to FERS, WEP may have reduced your Social Security retirement benefit. That reduction is now repealed. Check with SSA to confirm the adjustment was applied to your record.

What Did Not Change: The FERS-to-SSDI Offset

The most common point of confusion in federal retirement forums is conflating the WEP/GPO repeal with the FERS disability annuity offset against SSDI. These are entirely different legal mechanisms.

Under 5 U.S.C. § 8452, your FERS disability annuity is reduced by your SSDI benefit: 100% of SSDI in Year 1, and 60% of SSDI from Year 2 until age 62. This offset remains fully active. The Social Security Fairness Act did not touch it — the FERS statutory offset has a separate legal basis and serves a different purpose (preventing double payment for the same disability).

So if you're calculating your FERS disability annuity and wondering whether the Fairness Act eliminated the SSDI offset — it did not. Your Year 1 formula is still 60% of High-3 minus 100% of SSDI, and Year 2 onward is still 40% of High-3 minus 60% of SSDI.

Action Steps for FERS Disability Retirees

If you're currently receiving FERS disability retirement: Check whether any of your Social Security benefits (retirement, spousal, or survivor — not SSDI) were previously reduced by WEP or GPO. If so, SSA should have already applied the adjustment. Verify on your my Social Security account at ssa.gov.

If you never applied for a Social Security benefit because WEP or GPO would have zeroed it out: File a new claim with SSA. Automatic enrollment does not apply to people who never filed.

If you're currently applying for FERS disability retirement: The mandatory SSDI filing requirement under 5 CFR § 844.201 is unchanged. You must apply for SSDI and provide proof to OPM. The SSDI offset against your FERS annuity still applies. But if you also qualify for Social Security spousal or survivor benefits based on a spouse's record, those benefits are no longer subject to GPO.

The FERS Disability Retirement for Mental Health Conditions guide includes a financial planning worksheet that accounts for both the SSDI offset and the post-Fairness Act landscape, so you can project your actual income across the Year 1, Year 2, and age 62 conversion stages.
