Under PRWORA, Congress eliminated AFDC's open-ended entitlement and replaced it with TANF's State Block Grants. Although states still have flexibility to determine eligibility requirements and benefit levels under TANF, those benefits are subject to Federal time limits and work requirements. The Federal time limit is five years, though states can choose a shorter limit. In general, states must place adult TANF recipients in work no later than their twenty-fourth month of assistance. TANF recipients who do not satisfy the work requirements are subject to either reduced benefits or benefit termination, and states whose caseloads do not meet certain participation requirements are subject to financial penalties.
