This bill aims to prevent state and local governments from imposing financial requirements on firearm and ammunition ownership or commerce. It specifically prohibits mandates for liability insurance , taxes, user fees, or similar charges as a condition for manufacturing, importing, acquiring, transferring, or continuing to own firearms or ammunition. The legislation amends both Title 18 of the U.S. Code and the Internal Revenue Code to establish these prohibitions. While generally banning such fees, it makes an exception for generally applicable sales taxes , allowing them to be assessed on firearms and ammunition at the same rate as other goods and services. This measure seeks to remove financial barriers to gun ownership and related commercial activities at the state and local levels.
