The Three Classes
Your class follows your underlying license.
- Class 1 — Importer of NFA firearms
- Class 2 — Manufacturer of NFA firearms (pairs with a Type 07 or 10)
- Class 3 — Dealer in NFA firearms (pairs with a Type 01 or 02)
Filing And Tax Year
You register and pay using ATF Form 5630.7. The special tax year runs July 1 through June 30, so a mid-year registration still expires on June 30 and must be renewed for the next tax year.
Annual Renewal
SOT renews every year, and payment is made through Pay.gov. Missing the renewal means losing the ability to deal in or manufacture NFA items until it is cured. FFL Elite's SOT program includes a step-by-step Pay.gov renewal walkthrough.
Fees, forms and processing rules change through ATF rulemaking. Confirm current requirements with ATF and your state and local authorities before you file.
