Imposes gross receipts tax on firearms and firearms ammunition.

This bill imposes a 2.5% gross receipts tax on retail sales of firearms and a 10% tax on retail sales of firearms ammunition within New Jersey. It directly affects retailers selling these items in the state, excluding sales delivered outside New Jersey, mailed to out-of-state purchasers, or sold to federal, state, or local government entities. The tax applies to gross receipts from qualifying sales and must be reported monthly to the Division of Taxation. Definitions clarify that "firearms" include weapons expelling lethal projectiles via combustion, and "firearms ammunition" covers cartridges, components, and propellants. The tax takes effect 30 days after enactment for sales beginning in the first full quarter after that date.
