This bill would prohibit states and local governments from imposing excise taxes on firearms, ammunition, and related parts sold by manufacturers and dealers in interstate commerce. The legislation would essentially block the ability of states to collect their own special taxes on gun and ammunition sales, though it would not affect the existing federal Pittman-Robertson tax, which funds wildlife conservation programs. The bill affects gun manufacturers, dealers, and state governments that currently collect revenue from such taxes. No specific funding amounts or implementation timeline are specified in the bill text. The legislation was introduced in March 2025 by a group of Republican senators and was referred to the Senate Committee on Finance for review.
