What is the Windfall Elimination Provision?
The Windfall Elimination Provision (WEP) was a formula that could reduce the size of your Social Security retirement or disability benefit if you also received a pension from a job in which you did not pay Social Security taxes. Congress voted in December 2024 to repeal the WEP, ending benefit cuts for those receiving such “non-covered” pensions.
The repeal law, the Social Security Fairness Act, was retroactive to benefits paid for 2024, which meant people previously subject to the WEP would receive a lump-sum repayment of the benefits withheld during that year.

The Social Security Administration (SSA) says it adjusted monthly payment amounts for WEP-affected beneficiaries in February 2025 and completed sending retroactive payments in July to all those whose benefits were reduced by the provision in 2024. You can find more information on the act and its implementation on the Social Security website.
How did the Windfall Elimination Provision work?
Under the WEP, the SSA could reduce your monthly benefit payment by up to half of the amount of your pension. (By law, it could not eliminate your benefit; Social Security set a cap on the maximum reduction, which in 2024 was $587 a month.)
About 2.1 million people — roughly 3 percent of Social Security recipients — were affected by the provision, according to a February 2024 report by the Congressional Research Service. Most worked for state or local government bodies such as school systems, police and fire departments, and other public service agencies, many of which do not participate in the FICA payroll-tax withholding that provides most of Social Security's funding.
The WEP’s effect was proportional: The more years in which you did “covered” work (in which you paid Social Security taxes), the less the provision cut into your benefits. If you had 30 or more years of covered work, the WEP did not apply.
Congress approved the Windfall Elimination Provision in 1983 as part of a larger package of Social Security reforms (including an increase in the full retirement age). The intent was to remove an unintended advantage for workers who collect non-covered pensions but also did some "covered" work in jobs that paid into Social Security.
Because relatively little of their lifetime income was reflected in their Social Security earnings records, these workers benefited from Social Security’s progressive formula for figuring retirement payments, which is weighted in favor of low-wage workers. In other words, someone who collected a healthy government salary for decades received the same advantage in Social Security calculations as did a longtime low-income worker.
The WEP compensated for this by tweaking the formula for people also receiving non-covered pensions in a way that reduced their Social Security retirement benefits. Critics of the provision said it penalized public-sector workers who also paid into Social Security via other employment.
Another pension rule repealed
The Windfall Elimination Provision affected Social Security retirement and disability benefits. A separate rule, the Government Pension Offset (GPO), covered people who received spousal or survivor benefits in addition to a non-covered government pension.
The Social Security Fairness Act repealed both rules, and the SSA says it has also completed GPO-related adjustments and repayments. In all, the agency says it made 3.1 million retroactive payments totaling $17 billion to beneficiaries affected by the WEP and the GPO.
