Retroactive payments for 2024–2025 are primarily going to over 1.1 million retirees, spouses, and survivors—particularly police officers, firefighters, teachers, and federal employees (CSRS)—whose benefits were previously reduced by the Windfall Elimination Provision (WEP) or Government Pension Offset (GPO). These one-time, lump-sum payments cover benefits from January 2024 onward.
