Suppressors go through a Class 3 (SOT) dealer, and the federal tax on them has been $0 since January 1, 2026. You still pay the dealer's transfer fee. Some states only allow suppressors and SBRs that are federally registered or possessed in compliance with federal law. Check your state's statute before you buy.
