The main purpose of this legislative text is to redirect funding that was initially set aside for improvements to the Internal Revenue Service (IRS). The bill proposes to take back unspent money that was allocated for the IRS and instead use those funds to create and manage a new entity called the External Revenue Service. Key provisions of the bill include the rescinding of all unspent funds that were designated for enhancing the IRS under a previous law known as the Inflation Reduction Act of 2022.
