Suppressor and SBR law in 2026: what changed, what didn't

As of October 11, 2026. This page is not legal advice. Every claim below comes from a document you can read yourself; they are listed under Sources.

Bottom line

Congress cut the federal making and transfer tax on suppressors, short-barreled rifles, short-barreled shotguns and "any other weapons" to $0 effective January 1, 2026, a federal district judge then held that the National Firearms Act's registration and approval rules could no longer be justified for those four items, and on October 9, 2026 ATF said it will stop enforcing those rules against everyone. In a state that does not restrict them, you can now buy a suppressor the way you buy a rifle, on a Form 4473 and a NICS check, with no tax stamp, no fingerprints and no wait. None of this is a repeal, because ATF can change the policy back, there is no provision that would automatically grandfather an unregistered item if it does, and state law is untouched.

How it happened

July 4, 2025 — the tax goes to zero on paper. The One Big Beautiful Bill Act, Pub. L. No. 119-21, 139 Stat. 72 (2025), reduced the NFA making and transfer taxes to $0 for short-barreled rifles, short-barreled shotguns, silencers and "any other weapons" as defined in 26 U.S.C. § 5845(e). It left registration, the forms, the fingerprints and the registry in place.

January 1, 2026 — the $0 tax takes effect. The tax cut applies to the four item classes above. Machine guns and destructive devices keep the $200 tax.

August 5, 2026 — the ruling. A U.S. district judge in the Northern District of Texas enjoined ATF from enforcing the NFA's making, registration and transfer provisions as applied to the four untaxed classes, in Silencer Shop Foundation v. ATF, No. 6:25-CV-056-H, 2026 WL 2255460 (N.D. Tex. Aug. 5, 2026). The court held that with no tax there was no exercise of the taxing power left to support those rules, and that Congress had not relied on its commerce power when it passed the NFA in 1934.

August 12, 2026 — the injunction takes effect, for some people. ATF's letter gives the effective date as August 12, 2026, and says the injunction "applies only to the plaintiffs and to NFA firearms for which the One Big Beautiful Bill Act eliminated existing taxes." Everyone else was still bound. That is the part the general coverage got wrong — the court order was never nationwide.

October 5, 2026 — no appeal. The Department of Justice did not appeal and the window closed.

October 9, 2026 — ATF applies it to everyone. Director Robert Cekada issued an open letter to all federal firearms licensees and the public. Forty-seven members of the House and Senate had asked ATF to apply the ruling nationwide. The letter says that effective that day ATF "will no longer require individuals to seek ATF approval under the NFA before making or transferring" the four classes, and "will also no longer require such items to be registered in the National Firearms Registration and Transfer Record," and that "these policies apply uniformly to anyone otherwise subject to these requirements, not just to the plaintiffs in the litigation." A 24-question FAQ was issued the same day.

The nationwide part is ATF policy, not a court order. ATF says so itself, and its FAQ adds that a district court order "generally ha[s] no binding effect on other federal courts or on state courts" and that other courts "could reach different conclusions."

What you do at the counter today

A suppressor

Buy it, fill out a Form 4473 and pass a NICS check. ATF says licensees should process these transactions "as they would any other statutory 'firearms' under the GCA." There is no Form 4, no fingerprint card, no photo and no federal waiting period, because ATF has stopped requiring prior approval to transfer and stopped requiring registration in the NFRTR. The dealer still has to be an FFL, still keeps records, and still generally may only sell to residents of the state where it is licensed. Your dealer can still insist on running a Form 4 if it wants to. Nothing in the policy forces a dealer to change how it does business.

A short-barreled rifle or shotgun

Same counter process, with one piece of plumbing missing underneath it. The Gun Control Act still bars an FFL from selling or delivering an SBR or SBS "except as specifically authorized by the Attorney General" under 18 U.S.C. § 922(b)(4). NFA approval used to be that authorization. The court enjoined the NFA process and did not touch the GCA requirement, so ATF says "no regulatory mechanism exists" right now and that it will not enforce § 922(b)(4) until it writes one. That gap is why some dealers still refuse factory SBR sales. The sale rests on enforcement discretion covering a statute nobody has enjoined.

Taking an SBR or SBS across a state line

File an ATF Form 5320.20 first, even if the gun is unregistered. ATF's FAQ is explicit that individuals "must continue to file a Form 20 before engaging in interstate transportation of a short-barreled rifle or short-barreled shotgun, even if it is unregistered," citing 18 U.S.C. § 922(a)(4). The open letter uses softer wording and says people "should continue to file Form 20s," but the statute it points to was not enjoined either way. Suppressors and AOWs are not on the Form 5320.20 list and never were. ATF has also stopped enforcing 26 U.S.C. § 5861(j), the NFA provision that barred transporting an unregistered NFA firearm in interstate commerce.

Making your own

No Form 1 and no approval. ATF's FAQ says unlicensed individuals "no longer need to file a Form 1 and receive ATF approval before making or transferring such items," and may file one voluntarily if they want the item in the registry. You still may not engage in the business of making or transferring them without a license, and you may not transfer to a resident of another state or to anyone prohibited from possessing a firearm.

What did not change

Machine guns and destructive devices. The $200 tax stands and every NFA provision still applies to them.

The entire Gun Control Act. Suppressors and the rest are statutory "firearms" under 18 U.S.C. § 921(a)(3). Prohibited persons still may not possess them, and recordkeeping and background check requirements are all in place.

Serial numbers. The NFA marking requirement is among the rules ATF stopped enforcing, but GCA serialization by manufacturers is not. ATF's FAQ tells licensed manufacturers they "must serialize all firearms and silencers."

The special occupational tax. A business may not deal in these items without paying SOT. The court did not touch it.

State and local law. ATF's letter says the injunction and the policy "do not affect state or local laws that govern NFA weapons," and the GCA still bars an FFL from transferring in violation of state or local law under 18 U.S.C. § 922(b)(2).

No new statute. The Hearing Protection Act and the SHORT Act did not pass. Nothing has been removed from the NFA. Machine guns and destructive devices are proof of that, and so is the fact that ATF is still running the registry for anyone who wants to use it.

Where the risk sits

This is non-enforcement, not repeal. ATF spells out how it could end. "Material changes in legal or factual circumstances could cause NFA enforcement to resume. For example, Congress could impose a new tax on NFA firearms, the district court's injunction could be dissolved or overturned, or the Department could rescind the enforcement guidelines." The same answer adds that "the NFA treats unregistered firearms as contraband" and that people who make, possess, transfer or receive unregistered NFA firearms "are subject to felony penalties and forfeitures."

There is no grandfather clause. ATF says "[f]ederal law does not generally permit subsequent registration of unregistered NFA items nor are there provisions that would automatically grandfather unregistered NFA firearms." The Attorney General may hold an amnesty of up to 90 days, but "is not required… to hold an amnesty or to provide forbearance."

State law is the live problem. ATF's own words, in two separate answers, are that it "cannot opine on whether holding an unregistered firearm or silencer pursuant to ATF's enforcement discretion will qualify for state-law purposes as lawfully held (or registered) under federal law," and that people should "[c]heck with state and local authorities."

The § 922(b)(4) hole. Dealer sales of SBRs and SBSs currently rest on discretion covering a statute the court did not enjoin, and ATF has published no proposed rule to fix it.

Form 5320.20 is an easy thing to forget. Crossing a state line with an SBR or SBS without filing one is a GCA problem whether or not the gun is registered.

Driving through a state that bans the item. ATF says it "is unclear whether state courts will apply the safe harbor created by 18 U.S.C. § 926A to interstate transportation of unregistered NFA items," and that people "should exercise caution before transporting unregistered NFA items through states in which such items are prohibited by law, even if the items are not prohibited in the originating and destination states."

De-registration only goes one way. If you pull an item out of the registry, "it cannot be re-registered unless the Attorney General declares an amnesty."

If your state's law keys off federal registration

About twenty states make the legality of a suppressor, an SBR, or both turn on federal registration or federal compliance. The wording varies. Some say "registered under the National Firearms Act." Some say "in compliance with federal law." Some put it on you as an affirmative defense. ATF has expressly declined to say whether an item held under its enforcement policy satisfies any of them.

If you live in one of those states, file the Form 4 anyway. It costs $0 since January 1, 2026, ATF says it "will continue to maintain the National Firearms Registration and Transfer Record and approve all NFA forms for those who voluntarily wish to submit them," and a stamp keeps the state-law predicate intact at no cost. If you are making the item yourself in one of those states, the same point applies to a Form 1.

Check your own state's page for the wording of the statute that applies to you. We quote the section rather than tell you what a prosecutor in your county will do with it.

Questions people ask

Do I still need a tax stamp for a suppressor?

No. ATF stopped requiring prior approval to transfer and stopped requiring registration on October 9, 2026, and the tax has been $0 since January 1, 2026. Registration is available if you want it.

Are suppressors legal now?

Federally, ATF is not enforcing the registration and approval rules against anyone. Nine jurisdictions ban civilian suppressor possession outright under their own law, and ATF's policy does not change that.

Did Congress legalize suppressors?

No. Congress cut the tax to $0 in the One Big Beautiful Bill Act. The registration rules are still on the books and ATF is choosing not to enforce them.

Did the Supreme Court do this?

No. It was a single federal district judge in the Northern District of Texas, in a case about Congress's taxing power. ATF's own FAQ says the order does not bind other courts and that other courts could decide differently.

Can I walk out of the shop with a suppressor the same day?

Federally, yes, subject to the Form 4473 and the NICS check. Your state may have its own waiting period, and your dealer may have its own process.

Do I need a Form 1 to make my own suppressor or SBR?

No. ATF says unlicensed individuals no longer need to file one and receive approval first. You still cannot engage in the business without a license, and you still cannot transfer to an out-of-state resident.

Can I take an SBR to another state?

File a Form 5320.20 first. ATF says individuals must continue to file one before interstate transportation of an SBR or SBS, even if the gun is unregistered.

Can I take a suppressor to another state?

There is no Form 5320.20 for suppressors and ATF has stopped enforcing § 5861(j). The open thing is state law along the way, since ATF says it is unclear whether the § 926A safe harbor applies to unregistered items.

What happens to my unregistered suppressor if the policy is reversed?

ATF says federal law does not generally permit later registration of unregistered NFA items and that nothing automatically grandfathers them. An amnesty of up to 90 days is possible and is not required.

Should I register anyway?

If your state's statute conditions legality on federal registration or federal compliance, a voluntary Form 4 or Form 1 costs nothing and preserves that condition. ATF is still approving forms for anyone who files them.

Can I un-register a suppressor I already have a stamp for?

You can write the NFA Division at NFAFAX@atf.gov. ATF says that once an item is removed it cannot be re-registered unless the Attorney General declares an amnesty.

Are machine guns next?

No. The $200 tax on machine guns and destructive devices survived the One Big Beautiful Bill Act, and every NFA provision still applies to them.

Can my dealer still refuse to sell me one without a Form 4?

Yes. ATF stopped requiring the paperwork; it did not require anyone to drop it.

State by state

Each state's own law, from its statutes. "Ties to federal registration" means the statute makes legality depend on NFA compliance or registration, the case where filing the free Form 4 matters. Open a state for the statute text.
