Windfall Elimination Provision (WEP)

The Windfall Elimination Provision (WEP) is a modified formula used by the Social Security Administration to calculate retirement benefits for individuals who receive a pension from employment that was not covered by Social Security (meaning Social Security taxes were not paid on those earnings). This situation commonly arises with certain federal, state, and local government workers, as well as employees in some foreign countries.

The standard Social Security benefit formula is progressive, meaning it replaces a higher percentage of income for lower earners. WEP exists because without it, a worker who spent most of their career in non-covered employment would appear to be a low earner in the Social Security system and would receive a disproportionately high benefit relative to their covered earnings.

The WEP formula reduces the first factor in the Social Security benefit calculation from 90% to as low as 40%, depending on the number of years of substantial covered earnings. Workers with 30 or more years of substantial earnings covered by Social Security are exempt from WEP entirely. The maximum WEP reduction for 2025 is $621 per month, and the reduction cannot exceed more than half of the non-covered pension amount.

It is important to note that WEP affects only the worker's own benefit — it does not directly reduce spousal or survivor benefits (those may be affected by the related Government Pension Offset provision). Additionally, WEP does not apply if the non-covered pension is based on work before 1957, or if you receive benefits under certain exceptions.

The Social Security Fairness Act has been a topic of ongoing legislative discussion aimed at repealing or modifying WEP and GPO. Staying informed about potential legislative changes may be relevant for those affected by these provisions.
