A suppressor tax stamp is a federal tax paid to the U.S. government for the legal purchase of NFA (National Firearms Act) items, including silencers, short-barreled rifles (SBRs), and machine guns.
This tax is required by the ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) as part of the approval process for all Form 4 submissions.
Starting January 1st 2026, under the Big Beautiful Bill, all tax stamps will be included at no additional cost — making the effective tax stamp price $0 on all new orders.
