ATF NFA Guidance: No Form 4 or Registration for Suppressors, SBRs, SBSs and AOWs

New ATF NFA guidance ends Form 4, Form 1, registration and tax-stamp enforcement for suppressors, SBRs, SBSs and AOWs as of October 9, 2026.

As of October 9, 2026, ATF no longer requires its approval, federal registration or a tax stamp to make or buy a suppressor, short-barreled rifle, short-barreled shotgun or “any other weapon,” but the dealer background check, your state’s law and the Form 20 for taking an SBR or SBS across state lines all still apply, and machine guns have not changed at all.

What Did ATF Announce on October 9?

In over 20 years as a professional in the firearms industry, I have watched ATF tighten the NFA plenty of times. I have never watched it let go like this. On October 9, 2026, ATF Director Robert Cekada signed an open letter to all federal firearms licensees and the public, and ATF posted a page of frequently asked questions with it. Here is the heart of the letter, word for word:

“Effective October 9, 2026, ATF will no longer require individuals to seek ATF approval under the NFA before making or transferring short-barreled rifles, short-barreled shotguns, silencers, and “any other weapon[s]” as defined in 26 U.S.C. § 5845(e). ATF will also no longer require such items to be registered in the National Firearms Registration and Transfer Record.”

The next sentence is the one gun owners have been waiting since August to read: “These policies apply uniformly to anyone otherwise subject to these requirements, not just to the plaintiffs in the litigation.” ATF’s press release says the policy follows Attorney General Todd Blanche’s decision not to appeal the Texas ruling and to apply it to everyone, not only the people the court order covered. Cekada’s line in that release: “The direction from the President, Congress, and the courts is clear.” (I looked at his record in our profile of ATF Director Robert Cekada, and this is the biggest thing he has signed by a mile.)

Why Did ATF Stop Enforcing the NFA on These Items?

Two things got us here. First, the One Big Beautiful Bill Act cut the NFA making and transfer tax on suppressors, SBRs, SBSs and AOWs to $0 starting January 1, 2026, while the $200 stayed on machine guns and destructive devices. Second, on August 5, 2026, Judge James Wesley Hendrix of the U.S. District Court for the Northern District of Texas ruled in Silencer Shop Foundation v. ATF, No. 6:25-cv-056, consolidated with Jensen v. ATF, that once the tax hit zero, the NFA’s registration and approval rules for those items were no longer a valid use of Congress’s taxing power. ATF’s letter adds that the court refused to save them under the commerce power either, because Congress “did not rely on its power over interstate commerce when it first passed the NFA in 1934.” I covered that legal theory in our breakdown of why the NFA ruling turned on the taxing power.

The catch was that the injunction only protected the plaintiffs, their members and their customers, the Trump v. CASA problem I wrote about in September. Everybody else was stuck on the wrong side of a members-only rope line. The Justice Department let the October 5 appeal deadline pass, and ATF says it heard from litigants, Members of Congress, state attorneys general, the industry and the public, including an August 11 letter to the Attorney General from 47 members of the House and Senate, led by Rep. Andrew Clyde, asking for the ruling to be applied nationwide. ATF’s FAQ says the new policy is “designed to eliminate the inequity and disuniformity created by the district court’s injunction, which is limited only to certain parties.” Translation: the rope line is gone.

Do You Still Need a Tax Stamp for a Suppressor?

No, not under federal law. The tax on a suppressor has been $0 since January 1, 2026, and as of October 9, ATF stopped requiring the Form 4 approval and the registration that came with it. Buying a suppressor from a dealer now works like buying any other gun at the counter: you fill out a Form 4473, the dealer runs the NICS background check, and if the check comes back “proceed” and your state allows it, you take it home. No fingerprint cards, no passport photos, no eForms queue. (I will miss refreshing the eForms status page about as much as I miss dial-up.)

Two things ride along with that. ATF’s FAQ says that, with limited exceptions, dealers may sell these items only to residents of the state where they are licensed, so an online order still ships to a dealer in your state. And your state may still want the item registered, which is the part most people are going to get wrong (more on that below).

Which NFA Items Are Covered, and Which Are Not?

ATF drew the line at the tax. If Congress zeroed the tax on an item, ATF stopped enforcing the paperwork on it. If the $200 survived, so did every NFA rule. Measured against the October 9 letter and FAQ, here is where each NFA category stands.

An AOW, for anyone who has never owned one, is the NFA’s catch-all for concealable guns that are not ordinary pistols or revolvers: think pen guns, cane guns and smooth-bore pistols. They get the same treatment as suppressors in this guidance.

What Rules Still Apply Under the ATF NFA Guidance?

ATF’s letter lists five limits, and every one of them can still land somebody in trouble:

1. Business taxes. Anyone in the business of making, importing or dealing in NFA items still pays the special occupational tax. The court never touched it, so manufacturers and dealers (my shop included) still write that check.
2. Machine guns and destructive devices. The $200 tax and every NFA rule still apply, and the ban on civilian machine guns made after May 19, 1986, in 18 U.S.C. 922(o), is untouched.
3. The Gun Control Act. Suppressors, SBRs, SBSs and AOWs are still “firearms” under 18 U.S.C. 921(a)(3), so prohibited persons still cannot have them, and dealers still run the Form 4473, the background check and the recordkeeping.
4. SBR and SBS transport and sales. You still need ATF’s approval on a Form 20 before taking an SBR or SBS across state lines (18 U.S.C. 922(a)(4)). The dealer-sale rule in 922(b)(4) is on hold until ATF writes a replacement approval process.
5. State and local law. Nothing in the letter overrides it.

Two NFA crimes also stay fully in force for every item: possessing an NFA firearm with an obliterated serial number, and possessing one that was illegally imported (26 U.S.C. 5861(h) and (k)).

Can You Make a Suppressor or SBR Without a Form 1?

Federally, yes. ATF’s FAQ says it in one line: “unlicensed individuals no longer need to file a Form 1 and receive ATF approval before making or transferring such items.” ATF also stopped enforcing the NFA’s marking requirement on them.

What ATF did not do is make you a manufacturer. The Gun Control Act still bars an unlicensed person from being in the business of making or selling these items, from transferring one to a resident of another state, and from transferring one to anyone prohibited from having a firearm. Building one for yourself is a long way from building them for the neighborhood, and your state’s law applies to a homemade item exactly the way it applies to a store-bought one.

One more thing before you start cutting. If there is any chance you will want the item registered (for your state, for travel or for your own records), the safest order is to file the Form 1 and wait for the approval before you build it. ATF’s FAQ says federal law “does not generally permit subsequent registration of unregistered NFA items” once the legal ground shifts, so do not count on registering it after the fact.

Can You Sell a Suppressor or SBR to Someone Privately?

Under federal law, a sale between two people who live in the same state now works like any other private gun sale. The federal lines ATF’s FAQ points to for unlicensed sellers are no selling these items as a business, no transfers to residents of other states, and no transfers to anyone prohibited from having a firearm. Plenty of states draw more lines than that (several require a background check on private sales, and the registration-tied states below may want the item to stay registered), so check your state before you hand anything over. If the item is registered to you and you want it to stay registered to the new owner, a voluntary Form 4 is still how that happens.

What Happens to Pending Form 4 and Form 1 Applications?

ATF keeps processing them. The letter says ATF “will continue to administer the NFA on a voluntary basis” and will accept Form 1, Form 3 and Form 4 applications, and manufacturers can still report new items on a Form 2. The press release explains why: “Because many state laws require individuals to register NFA firearms, ATF will continue to process NFA applications that are submitted.”

If you want out, ATF’s FAQ says to write the NFA Division at NFAFAX@atf.gov to withdraw a pending application or to remove an item that is already registered. Read the next sentence before you hit send: “once an item is removed, it cannot be re-registered unless the Attorney General declares an amnesty.” The guidance says nothing about refunds for the $200 stamps people paid before 2026, so do not hold your breath on that one.

Should You Still Register Your Suppressor or SBR?

This is the question I expect to hear most at the counter, and ATF answered the scary half of it in its own FAQ. It lists three ways enforcement could come back: “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.” If that happens, the NFA still “treats unregistered firearms as contraband,” with felony penalties and forfeiture, and ATF says there is no automatic grandfathering. The NFA lets the Attorney General hold an amnesty of up to 90 days, but nobody is required to hold one.

So here is how I would think it through:

• If your state’s law ties legal possession to federal registration, register. That is the only answer that is clean under both sets of law.
• If your suppressor or SBR is already registered, I would leave it registered. Once it comes off the books, it does not go back on without an amnesty.
• If you travel with it, especially an SBR, a registered item and an approved Form 20 are the cleanest paperwork you can carry.
• If you live in a state with no suppressor law and you are comfortable with the policy risk, ATF has said it will not come after you for skipping registration. Notice I said it WILL not, not that it cannot.

Can You Travel Across State Lines With a Suppressor or SBR?

With a suppressor or an AOW, ATF says yes. The NFA makes it a crime to move an unregistered NFA firearm across state lines (26 U.S.C. 5861(j)), and ATF says it will not enforce that against anyone, covered by the injunction or not. Its FAQ explains why: enforcing 5861(j) would make it hard to ship between dealers or send a suppressor back to the maker for repair, and individuals could not go target shooting in another state or move with one.

An SBR or SBS is different, because that rule lives in the Gun Control Act, not the NFA. In ATF’s words, “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.” That is ATF Form 5320.20, and you still wait for the approval before you leave. If you saw a headline saying ATF still requires approval for interstate travel, that line in the press release is about SBRs and SBSs, not suppressors.

Then there is the route. ATF’s letter warns that “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.” In plain English, the federal safe-passage law that protects you while you drive through a strict state may not cover an unregistered suppressor, so plan your route around the ban states instead of through them.

What Do Gun Dealers Have to Do Now?

On my side of the counter, the change is easy to describe and a project to put in place. ATF tells dealers to process suppressors and AOWs “as they would any other statutory ‘firearms’ under the GCA”: a Form 4473, a NICS check unless an exemption applies, the records, in-state buyers only with limited exceptions, and nothing that breaks state or local law. Dealer-to-dealer sales of suppressors and AOWs no longer need a Form 3, though one can still be filed voluntarily, and a dealer who already sold an NFA item on a 4473 can ask ATF to take it off the shop’s NFA inventory by writing NFAFAX@atf.gov.

SBRs and SBSs are the odd ones out. The Gun Control Act bars a dealer from selling one “except as specifically authorized by the Attorney General” (18 U.S.C. 922(b)(4)), and the NFA approval used to be that authorization. ATF admits that “no regulatory mechanism exists” yet, says it is “creating forms and drafting regulations as quickly as possible,” and will not enforce 922(b)(4) until those rules exist. Some shops will wait for the forms anyway, and I would not blame them. And no, a dealer who does not pay the special occupational tax cannot jump into the NFA business because the paperwork got lighter.

Does Your State Still Require NFA Registration?

This is where most people will get tripped up. From ATF’s FAQ: “Most states require that individuals who possess NFA items comply with federal law or register them under the National Firearms Act.” ATF also says it “cannot opine” on whether an item held under this policy counts as lawfully held, or registered, for state-law purposes. That is a big reason ATF is keeping the registry open.

For suppressors, the states sort into three groups:

• Ban states. California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island and Washington, D.C. ban civilian suppressor ownership, and nothing ATF did touches that. Our state-by-state suppressor guide covers each one.
• Registration-tied states. These allow suppressors only when the item is registered or held in compliance with federal law. Silencer Shop’s August list put 15 states in this group, and Popular Suppressors mapped which states fall in each group. In these states a registered suppressor is the safe path, and a voluntary Form 4 or Form 1 is how you get one.
• States with no suppressor law of their own. Here the federal change is the whole story. Read your state’s SBR and SBS laws separately, though, because short-barrel rules are written apart from suppressor rules and do not always match.

Update, Oct 11, 2026: On October 9, Firearms Policy Coalition asked the attorneys general of the 15 registration-tied states to stop enforcing those laws now and then work toward repeal (FPC’s letters to the 15 states). When we checked on October 10, we found no reply from any of them. ATF’s October 9 announcement says its guidance “does not supersede state and local laws,” so if you live in one of those 15 states, nothing changes for you until your attorney general or legislature acts.

Dealers are bound by the same line. The Gun Control Act still bars a dealer from selling any firearm in violation of state or local law (18 U.S.C. 922(b)(2)), and ATF warns that dealers who willfully do it “face federal criminal penalties and license revocation.” So if your local shop keeps running Form 4s for a while, that is not stubbornness. That is a dealer who would like to keep his license.

Is the NFA Gone for Good?

No. The National Firearms Act still sits in Title 26 word for word. What changed is that the Justice Department decided not to enforce parts of it for four kinds of items, and ATF’s own FAQ names the three ways that could end. Only Congress can take suppressors and short-barreled guns out of the NFA for good. Until it does, this is a policy, and a future administration could undo it with a letter just like this one.

Other courts are not bound by the Texas ruling either. ATF’s FAQ says so, and the Third Circuit held on September 1, 2026, in United States v. Berger, that silencer registration does not violate the Second Amendment. That was a different legal argument from the Texas tax case, but it shows how fast the ground can shift.

The lawsuits keep going. In the Texas case, the government owes the court its answer on the plaintiff states’ request to clarify who is covered by October 12, 2026. In Missouri, Brown v. ATF has a status conference on October 22, 2026, and our map of the Brown and Roberts cases explains why gun-rights groups still want a ruling that does not depend on who runs the Justice Department. The Second Amendment Foundation put it plainly in its statement on the guidance: it “cannot, and does not, provide a permanent fix.” Rep. Clyde, for his part, called it the “biggest restoration of Americans’ 2A rights in history.” I covered where the court case stood before this letter in our update on NFA registration being struck down.

Frequently Asked Questions

Is the $200 tax stamp gone?

For suppressors, SBRs, SBSs and AOWs, yes. The tax has been $0 since January 1, 2026, and ATF stopped enforcing the stamp and registration requirements on October 9, 2026. Machine guns and destructive devices still carry the $200 tax.

Do I need a Form 4 to buy a suppressor now?

No, not under federal law. A dealer runs a Form 4473 and a background check instead. Your state may still require registration, and ATF will process a Form 4 if you choose to file one.

Can I buy a suppressor online?

You can order one online, but it ships to a licensed dealer in your state, who runs the Form 4473 and background check before you take it home.

Do I still need a Form 20 to travel with an SBR?

Yes. The Gun Control Act still requires ATF approval before an SBR or SBS crosses state lines, registered or not. A suppressor does not need a Form 20.

Can I remove my suppressor from the NFA registry?

Yes, by writing the NFA Division at NFAFAX@atf.gov. Once it is removed, it cannot be re-registered unless the Attorney General declares an amnesty.

Read your state’s statute before you order, not after. Keep every approval and receipt you already have. And if you are torn on registering, remember the math: one email takes an item off the registry, and no number of emails puts it back. Have safe and legal range days.
