What was the Windfall Elimination Provision?
WEP cut the Social Security of people who also earned a pension from work that didn't pay Social Security tax — many teachers, police officers, firefighters and federal workers hired before 1984. Instead of replacing the first slice of earnings at 90%, the formula used as little as 40%. (SSA POMS: WEP formula)
| Years of substantial covered earnings | First-slice rate under WEP |
|---|---|
| 20 or fewer | 40% |
| 21 | 45% |
| 25 | 65% |
| 29 | 85% |
| 30 or more | 90% (no reduction) |
Two limits softened it: the cut could never be more than half your non-covered pension, and 30 years of substantial earnings exempted you entirely. The calculator applies both, using the bend point for the year you turned 62.

Social Security Fairness Act Payments: Retro Pay and the Monthly Raise
The repeal brought two payments. A higher monthly check, starting with the April 2025 payment, and a one-time retroactive payment covering the higher amount back to January 2024. Both went out automatically to people already receiving benefits. (SSA: Social Security Fairness Act)
The monthly raise equals what WEP had been taking, grown by every cost-of-living adjustment since you turned 62 — 3.6% more in 2027. The calculator shows it in 2027 dollars. Your exact figure also depends on SSA's rounding and the month you started.
If your check didn't change, log in to your my Social Security account, compare the benefit letters, and call SSA if the new amount is missing.

Our take: verify, don't assume
The repeal is permanent law, but your amount still depends on SSA having your pension and earnings data right. Five minutes with your benefit letter is worth it.
Married or widowed too? The same act ended the Government Pension Offset, which may pay you a spouse or survivor benefit for the first time. To see where your restored benefit comes from, run the Social Security formula, and if you haven't claimed yet, pick an age on the break-even calculator.
