This bill, known as the "Return to Sender Act," aims to eliminate certain funding provisions established by the Inflation Reduction Act. Specifically, it proposes to repeal sections 70002 and 70003 of Public Law 117-169, which is commonly referred to as the Inflation Reduction Act. Furthermore, the legislation mandates the rescission of any unobligated balances of funds that were appropriated or made available under these two sections as of the bill's enactment date. The practical impact of this bill would be to remove significant funding allocated to the Internal Revenue Service for purposes such as enforcement and operations support.
