This final rule adopts, with clarifying changes, the proposed rule we previously published in the Federal Register on August 3, 2007. This final rule revises our Government Pension Offset (GPO) regulations to reflect changes to the Social Security Act ("Act") made by section 9007 of the Omnibus Budget Reconciliation Act of 1987 (OBRA 1987) and section 418 of the Social Security Protection Act of 2004 (SSPA). These regulations explain how and when we will reduce the Social Security spouse's benefit for some people who receive Federal, State, or local government pensions if Social Security did not cover their government work.
