Windfall Elimination Provision (WEP)
The Windfall Elimination Provision or WEP applies to a benefit you earned because of private sector employment. A modified benefit formula is used to calculate your Social Security benefit amount if you receive an MPERS pension, resulting in a lower Social Security benefit. Its purpose is to remove an unintended advantage or “windfall” that you might otherwise receive as a result of the interaction between the regular Social Security benefit formula and a relatively short career in Social Security-covered employment.
