I paid into SS and have my 40 quarters and also paid into FERS and am fully vested. Is my SS reduced because of double dipping?
No. Your Social Security benefits wouldn't be reduced due to receipt of a FERS (Federal Employee Retirement System) pension, because earnings covered under FERS are also subject to Social Security taxes. Social Security benefits are only subject to reduction under the Windfall Elimination Provision (WEP) if a person receives a pension based on their work that was exempt from Social Security taxes.
