1. The federal tax to make or transfer a short-barreled shotgun (SBS) is now $0.[1][2] 2. Since October 9, 2026, ATF says it is not enforcing NFA approval and registration for SBSs, SBRs, suppressors and certain AOWs.[3] 3. That does not change your state's law — and many states only allow an SBS that's registered under the NFA.[4] 4. ATF says this policy could end.[5]
What counts as a short-barreled shotgun
Federal law calls a shotgun "short-barreled" if its barrel is under 18 inches, or if it's a weapon made from a shotgun with an overall length under 26 inches.[6] A "shotgun" itself is defined as a gun designed and intended to be fired from the shoulder.[7]
That shoulder part is why the Mossberg Shockwave and Remington TAC-14 aren't SBSs at all: they ship with a bird's-head grip instead of a stock, aren't designed to be fired from the shoulder, and are over 26 inches long — so federally they're plain "firearms."[8][9] Mossberg warns that swapping the grip for a buttstock may change that classification.[9]
How we got here: the timeline
| Date | What happened |
|---|---|
| Jul 4, 2025 | Public Law 119-21 — widely called the One Big Beautiful Bill Act — is signed.[10] It cuts the NFA making and transfer tax to $0 for SBSs, SBRs, suppressors and AOWs; machine guns and destructive devices stay at $200.[2] |
| Jul 4, 2025 | Silencer Shop Foundation v. ATF is filed in the Northern District of Texas, arguing the NFA's rules can't apply to untaxed items.[11] |
| Aug 1, 2025 | Brown v. ATF is filed in the Eastern District of Missouri with a similar challenge.[12] |
| Jan 1, 2026 | The $0 tax takes effect.[1][13] Registration, photos, fingerprints and CLEO notice were still required at this point.[13] |
| Aug 5, 2026 | The Texas court enters final judgment for the plaintiffs in Silencer Shop.[14] |
| Oct 5, 2026 | The government's deadline to appeal passes with no appeal.[15] |
| Oct 9, 2026 | ATF announces it will stop enforcing NFA approval and registration for these items nationwide.[3] |
| Oct 22, 2026 | Status conference scheduled in Brown v. ATF, which is still pending.[15] We'll update this page after it. |
What you still have to do (federally)
- Buy through a dealer the normal way. An SBS is still a Gun Control Act firearm, so the dealer still completes a Form 4473 and runs a NICS background check.[5]
- File a Form 20 before you cross state lines with it. ATF says this still applies, registered or not.[5]
- Follow your state and local law. ATF's guidance doesn't override it, and dealers still can't transfer an SBS where state or local law forbids it.[4]
One odd wrinkle: federal law separately bars dealers from selling SBSs without specific authorization. ATF says it won't enforce that rule until it writes new regulations.[5]
Should you still register? Why some owners will
Form 1 (making) and Form 4 (transferring) are now voluntary, and ATF says it will keep approving forms people submit.[5][3] ATF's own reason for keeping the process open: many state laws require NFA firearms to be registered.[4]
Your state. In many states, owning an SBS is legal only if it's registered under the NFA. Reporting on the new policy points to states such as Ohio, Michigan, Georgia and Alaska, where the state exception or defense refers to federal registration — and notes a Form 4473 alone doesn't put an item in the federal registry.[16]
Reversal risk. ATF warns enforcement could resume, and federal law generally doesn't allow unregistered NFA items to be registered later.[5]
Right now our state checker lists 39 jurisdictions where an SBS is legal only with NFA registration, and SBSs are prohibited in: California, Delaware, District of Columbia, Hawaii, Illinois, Massachusetts, Minnesota, New Jersey, New York, Rhode Island, Washington. Check your state.
What we still don't know
- How long ATF takes on voluntary forms — ATF doesn't publish a processing time we could cite.
- Whether a vertical foregrip changes a Shockwave or TAC-14's classification — we couldn't find an ATF or maker statement on it, so we're not guessing.
- What Brown v. ATF will add after the October 22 status conference.
FAQ
Do I still need a tax stamp for a short-barreled shotgun?
No. The federal making and transfer tax for short-barreled shotguns is $0 as of January 1, 2026, and since October 9, 2026 ATF says it is not enforcing NFA approval and registration for them. State law may still require registration.
Is registering an SBS with ATF still possible?
Yes. ATF says Form 1 and Form 4 filings are now voluntary and it will keep processing them, largely because many state laws still require NFA registration.
Can I take an SBS to another state?
ATF says you must still file a Form 20 before transporting a short-barreled shotgun across state lines, and the destination state's law applies.
Is a Mossberg Shockwave an SBS?
No. It is classified as a Gun Control Act 'firearm,' not a shotgun, because it isn't designed to be fired from the shoulder and is over 26 inches long. Adding a buttstock may change that. Some states treat these differently.
Could the rules change again?
Yes. ATF says enforcement could resume if the court ruling is overturned, Congress acts, or the policy is rescinded, and federal law generally doesn't allow late registration.
