This bill aims to significantly alter the operational capabilities of the Internal Revenue Service by prohibiting its involvement with firearms and ammunition. It explicitly states that no appropriated funds may be used by the Commissioner of Internal Revenue to purchase, receive, or store any firearms or ammunition. Within 120 days of enactment, the bill requires the IRS to transfer all existing firearms and ammunition under its control to the Administrator of General Services. Following this transfer, the Administrator must initiate the sale or auction of these firearms to licensed dealers and ammunition to the general public, with all proceeds dedicated to federal deficit reduction. A major provision of the bill also transfers the responsibility for administering and enforcing criminal provisions of internal revenue laws from the IRS to the Attorney General and the Department of Justice. This includes the transfer of authorities, functions, personnel, and assets of the Criminal Investigation Division (CID) of the IRS , which will be maintained as a distinct entity within the Criminal Division of the Department of Justice.
