H.R. 4435 would reduce budgetary levels for any federal program that lacks an authorization of appropriations over a three-year period starting in fiscal year 2024. The bill defines budgetary levels as spending allocations provided to the Committee on Appropriations of the House or the Senate. CBO tracks authorizations of appropriations that have specified expiration dates and annually identifies appropriations provided for expiring and expired authorizations. Most recently, 1,108 authorizations of appropriations have been identified as having expired before the beginning of fiscal year 2023; 355 authorizations are set to expire before the end of 2023. CBO also identified $510 billion in appropriations for 2023 that were associated with 428 expired authorizations.
