What is a Class 3 Firearms License?
The term “Class 3 License” commonly refers to a Class 3 Special Occupational Taxpayer (SOT) registration that Federal Firearms Licensees can obtain to deal in items regulated under Title II of the National Firearms Act (NFA). This NFA item dealer license designation allows qualified firearms dealers to legally possess, transfer, and sell regulated NFA firearms and NFA firearms to qualified customers or other SOTs across the United States.
Class 3 SOT holders face additional ATF and Department of Treasury oversight and must maintain strict compliance with additional federal, state, and local laws governing NFA firearm transactions and/or prohibitions. This elevated status requires meticulous recordkeeping and adherence to specialized transfer procedures that go beyond standard firearm transactions, including federal registration, FBI identification and background check requirements, and tax stamp coordination (at this time).
This elevated status requires meticulous recordkeeping and adherence to specialized transfer procedures that go beyond standard firearm transactions. Machine guns and destructive devices remain subject to NFA approval and registration requirements, with a $200 tax on taxable transfers. Under ATF’s October 9, 2026 guidance, the agency is no longer enforcing prior NFA approval, registration, or related tax-stamp requirements for suppressors, short-barreled rifles, short-barreled shotguns, and AOWs. ATF continues to accept voluntary NFA applications for these items. Other applicable federal, state, and local requirements remain in effect.
Types of NFA Items That a Class 3 SOT Can Work With
Class 3 SOT licensees can legally handle various categories of NFA-regulated items:
- Short-Barreled Rifles (SBRs) – Rifles with barrel length shorter than 16 inches or overall length under 26 inches.
- Short-Barreled Shotguns (SBS) – Shotguns with barrel length shorter than 18 inches or overall length under 26 inches.
- Suppressors/Silencers – Sound suppression devices for firearms that require tax stamp approval.
- Machine Guns – Full auto firearms or devices, representing the most regulated NFA weapons category.
- Any Other Weapons (AOWs) – Unique NFA devices like cane guns, pen guns, and disguised weapons.
- Destructive Devices – Large caliber weapons and explosive devices requiring special federal government authorization (requires a Type 09, Type 10, or Type 11 FFL).
Obtaining a Class 3 SOT License
Before submitting your application for Class 3 SOT status, you must hold a valid Federal Firearm License. Eligible firearm license types include:
- Type 01 FFL – Dealer in firearms other than destructive devices
- Type 02 FFL – Pawnbroker dealing in firearms
- Type 09 FFL – Dealer in destructive devices
The application process requires submitting a completed application (ATF Form 5630.7) along with the necessary annual tax payment. Whether operating as a sole proprietor or any other legal entity type, this registration must be renewed yearly by July 1st via a renewal application, and ongoing compliance with additional federal, state, and local firearms regulations is mandatory.
What FFLs Should Know About the Class 3 SOT
Operating as a Class 3 SOT involves several critical responsibilities that differ significantly from standard firearm dealer operations:
- Enhanced Recordkeeping – Detailed tracking of all NFA item acquisitions, transfers, and inventory with specialized documentation requirements beyond typical dealer license obligations.
- NFA Transfer Process – Dealers must follow the applicable approval, registration, and tax requirements for machine guns and destructive devices. For suppressors, short-barreled rifles, short-barreled shotguns, and AOWs, ATF accepts NFA applications voluntarily. Dealer transfers of these items to unlicensed persons still require Form 4473 and, unless an exemption applies, a NICS background check.
- Inventory Management – Proper storage and security protocols for regulated NFA firearms with regular inventory accountability, often requiring enhanced security measures.
- State and Local Law Compliance – Understanding varying state and local regulations regarding NFA item possession, ownership and transfer restrictions, including special license/permission requirements in certain jurisdictions.
- Stricter ATF Compliance Expectations – Meeting elevated standards for inspections, audits, and regulatory adherence, including impeccable documentation and filing for all transactions.
- Market Opportunities – Access to specialized customer segments, including firearm enthusiasts seeking NFA items for personal use, collectors building a personal collection, and law enforcement agencies requiring specialized equipment.

FAQs
In order to get a Class 3 SOT, you must first obtain and maintain a valid FFL (Type 01, 02, or 09) before submitting your application for Class 3 Special Occupational Taxpayer status.
The annual Special Occupational Tax (SOT) fee for a Class 3 dealer is $500, provided the business’s gross receipts are under $500,000 per year. If receipts exceed that threshold, the fee increases to $1,000. The SOT tax year runs from July 1 to June 30, and payment must be submitted using ATF Form 5630.7 before July 1 each year for renewals. This fee is separate from your FFL renewal, which operates on a three-year cycle.
A Class 1 SOT allows importing NFA items, a Class 2 SOT permits manufacturing NFA items, and a Class 3 SOT enables dealing NFA firearms under federal law.
While not federally required, specialized insurance and enhanced security measures are recommended due to the increased liability exposure and valuable nature of short barrel rifles, machine guns, and other NFA devices.
