Requires both the House and Senate to complete two key budget actions — approving a concurrent budget resolution and enacting all regular appropriations bills — before the start of the fiscal year. If those actions are not finished by October 1 each year, affected Members of Congress may have pay withheld for the periods of noncompliance, and the withholding cannot later be repaid for those periods. The chamber budget and appropriations chairs certify compliance each year at the request of chamber administrative officers. The law takes effect September 29, 2027.
