What WEP did. A Social Security benefit is computed by running your average indexed monthly earnings through a three-tier progressive formula. The first tier replaces the largest share, 90 cents on the dollar, because it exists to protect low lifetime earners. WEP replaced that 90% factor with a substantially smaller one, on the theory that a worker with a modest covered earnings record but a substantial non-covered pension only looks like a low earner because most of their career is invisible to Social Security. The reduction phased out with years of substantial covered earnings, disappearing entirely at 30 years, and a separate guarantee capped it at half the non-covered pension.
What GPO did, and why it hit harder. GPO reduced a spousal or survivor benefit by two-thirds of the monthly non-covered pension. Because that offset was measured against the pension rather than against the Social Security benefit, a moderate government pension could exceed one and a half times the spousal benefit and erase it completely, which is exactly what happened to many surviving spouses. (The offset was originally dollar-for-dollar; Congress softened it to two-thirds in 1983.) In 2022, its last full year of ordinary operation, GPO applied to roughly 735,000 spousal and widow(er) beneficiaries, about 12.6% of that population.
Who the two rules reached. Teachers in the states whose systems opted out of Social Security, firefighters, police officers, other municipal employees, federal retirees under the older Civil Service Retirement System, and people drawing a foreign social security pension. Both rules were widely resented for reasons beyond the money: the arithmetic was opaque, and many people learned of it only when a benefit statement arrived, long after the career decisions were irreversible.
What the repeal did, and did not, fix. Social Security recomputed affected benefits without either adjustment and issued retroactive payments back to January 2024, completing over 3.1 million payments worth roughly $17 billion by July 2025. But the Act removed formula adjustments, not the underlying arithmetic of a short covered career. Your benefit is still based on your highest 35 years of Social-Security-covered earnings, and years in non-covered work enter that average as zeros. A teacher with twelve covered years still has twenty-three zeros, and her benefit is still modest. People routinely attribute that outcome to WEP and expect the repeal to have cured it. It could not: that is how the formula treats any gap in covered earnings.
The cost, stated plainly. Repeal was popular and its beneficiaries were largely career public servants on modest pensions, but it was not free. Social Security's Office of the Chief Actuary estimated it moved projected trust-fund depletion forward by roughly six months and worsened the program's long-range actuarial balance by about 0.14% of taxable payroll. The policy argument the two rules rested on was also not frivolous: the progressive formula assumes a short covered record means low lifetime earnings, and for these workers that assumption was false.
