ATF no longer requires Form 4 approval for suppressors. Confirm fit and state law, then buy on a Form 4473 dealer transfer or file a voluntary $0-tax eForm 4 for state registration, trust ownership, or a registered record.

Since October 9, 2026, ATF does not require Form 4 approval to buy a suppressor. Confirm the can, state law, ownership method, and travel plan, then buy on Form 4473 or file a voluntary $0-tax eForm 4 for a registered record.
The One Big Beautiful Bill Act, signed in July 2025 and effective January 1, 2026, zeroed the $200 NFA making and transfer tax on suppressors, SBRs, SBSs, and AOWs. For applications finalized in July 2026, ATF reported average processing times of 9 days for individual eForm 4 and 33 days for trust eForm 4. Individual waits can be longer. Our suppressor tracker carries current windows by filing type.
A federal judge struck down NFA registration for suppressors and SBRs on August 5, 2026 in Silencer Shop Foundation v. ATF, but that injunction covered only the plaintiffs, their members, and their customers. On October 9, 2026, the Justice Department extended the result to everyone as a matter of enforcement discretion: ATF no longer requires Form 4 approval or NFA registration for suppressors, SBRs, SBSs, and AOWs. A dealer sale now runs on Form 4473 and NICS, with no fingerprints, passport photo, CLEO notice, or ATF pre-approval wait. The statute was not repealed, state law still applies, and ATF still accepts Form 4 voluntarily; our Form 4 article covers when filing one still makes sense. The suppressor buying guide ranks cans by caliber; the suppressor compatibility basics guide covers thread, mount, and over-gassing.
The open question is state law. Most states tie NFA-item possession to federal registration or federal compliance, and ATF says it cannot opine on whether an unregistered suppressor held under its enforcement discretion counts as lawfully held for state purposes. Non-enforcement can also end: ATF says enforcement could resume if Congress imposes a new tax, the injunction is overturned, or the Justice Department rescinds its guidelines, and there is no automatic grandfathering for unregistered items. A voluntary $0-tax eForm 4 keeps the can on the registry.
Start with the gun you shoot most and match the can and thread pitch to it. A 9mm pistol with a tilting barrel also needs a booster (Nielsen device) so the action cycles with the can attached.
A 5.56 can earns its keep on an AR-15, a 9mm can quiets a pistol and doubles on a PCC, a .30-cal multi-host can covers a whole safe with one can, and a rimfire can is the cheapest way to start. S&W sells M&P GVAC upper receivers direct for a suppressor-ready AR: a pinned low-profile gas block that manages blowback at the source, in three 5.56 configs with the BCG included. The suppressed home-defense build prices host, optic, and can together.
Four cans that make sense as a first stamp, sorted by host. Match the can to the gun you shoot most and confirm the thread before you file.

Deep dives by host: best 5.56 suppressors ranks AR-15 cans by suppression score, best 9mm suppressors covers threaded handgun hosts, best .300 Blackout suppressors the subsonic crowd, best .300 Win Mag suppressors the magnum-rated cans, best .22 suppressors rimfire first cans, best multi-caliber suppressors the one-can picks from 9mm to .308, and best shotgun suppressors the six choke-mounted 12-gauge cans.
The default federal path is now a standard dealer sale: Form 4473, a NICS background check, and the dealer's records. FFLs generally sell only to residents of their own state, and they may not transfer a suppressor in violation of state or local law, so buy from a dealer in your state of residence.
If you want the suppressor registered, because your state requires it, you want trust ownership, or you want a registered record, choose the voluntary eForm 4 service model that is easiest to complete. A local Class III dealer provides in-person help. A kiosk-assisted dealer can capture fingerprints and pre-fill the eForm. A remote dealer can manage the Form 4 process and arrange delivery after approval.
A local Class III (SOT) dealer is the traditional route. You buy the can in the shop, the dealer files the Form 4 on your behalf, and you return to pick it up once approved. This is the best path if you want a person across the counter to walk you through the form and answer mount and thread questions on the spot.
A kiosk-assisted dealer can capture your fingerprints, demographics, and signature digitally and pre-fill the Form 4. The service may also store your biometrics for later filings. You still complete the dealer's pickup steps after ATF approval.
A remote Form 4 dealer can manage the application without an initial store visit and arrange delivery after approval, where state and federal rules allow it. This model can help buyers who live far from a Class III dealer, but confirm the delivery and identity-verification steps before ordering.

Register as an individual if you are the only person who will ever possess the can and you want the cheapest, fastest path. Use an NFA gun trust if you want more than one person to legally handle the suppressor or you want the trust to keep holding it after your death. A corporation is rarely the right answer for a single private buyer and mostly makes sense for dealers and businesses. Here is how the three compare for a normal first-time buyer.
This choice only applies to a voluntary eForm 4. A Form 4473 sale is made to you as an individual, so trust or entity ownership means filing the Form 4.
| Registration | Setup Cost | eForm 4 Wait (July 2026) | Who Can Possess It | Best For |
|---|---|---|---|---|
| Individual | $0 beyond the can | 9 days average (July 2026) | Only you, while present | Solo owners who want the simplest, fastest stamp |
| NFA gun trust | ~$100-300 to draft | 33 days average (July 2026) | Any named trustee (spouse, family) | Shared possession and passing the can to an heir |
| Corporation | Filing + annual fees | Varies | Authorized officers | Dealers and businesses, not private buyers |
The tax being $0 changed the trust math. People used to buy a trust partly to amortize the old $200 stamp across multiple items. Now the reason to use a trust is purely possession and inheritance: a trust lets your spouse or adult kids legally use the can without you standing next to them, and because the trust itself keeps owning the suppressor when you die, a successor trustee takes over with no new transfer. Without a trust, keeping a registered can on the registry when it passes from an estate to an heir means a tax-free ATF Form 5. Solo owners with no shared-possession or inheritance plans should file as an individual and save the trust drafting fee.
Since October 9, 2026, Form 4473 alone is the federal default wherever state law allows it. Every dealer transfer still includes Form 4473 and a NICS background check, but ATF no longer requires Form 4, fingerprints, a passport photo, CLEO notification, or a separate ATF approval wait for a suppressor.
File a voluntary eForm 4 if your state ties suppressor possession to federal registration, you are buying into a trust, or you want a registered record in case federal enforcement resumes. The dealer starts the application and you certify your section. The federal transfer tax is $0 for suppressors, and electronic filing is much faster than the old paper process.
One distinction trips up first-timers: Form 4 is for buying an existing suppressor from a dealer. ATF Form 1 is for making your own suppressor, which is a separate application and out of scope here; since October 9, 2026, both are voluntary for suppressors. If you are leaning toward making one, read what ATF's Form 1 parts-photo request means for builders first, because the filing order matters more than the paperwork.
Suppressors are not the only $0-tax NFA buy worth knowing about. If you are weighing a short-barreled rifle on the same trip, the best SBRs guide covers the same federal changes for those builds, plus the Form 20 an SBR still needs before interstate travel.
A voluntary Form 4 applicant submits fingerprints and a passport-style photo, and you send a notification copy to your chief law enforcement officer (CLEO). Fingerprints go in either as two FD-258 cards or as an electronic capture at a kiosk. Some filing services store the digital prints for reuse and accept the photo through an app. For an individual filing, the responsible person is just you. For a trust, it is every trustee.
A Form 4473 transfer skips those Form 4 attachments, but it does not skip the dealer background check. Complete Form 4473, pass NICS, and keep the bill of sale with the suppressor.
The CLEO notification is still part of every Form 4 filing. The ATF published a proposed rule in May 2026 to remove the CLEO notification requirement (RIN 1140-AA65), with a public comment period that closed July 6, 2026. That is a proposed rule, not a final one. Until the ATF publishes a final rule, a voluntary Form 4 still includes the CLEO copy.
A NICS background check runs as part of the transfer. This is the same check you pass to buy any firearm from an FFL, and it is why a suppressor purchase is gated to people who can legally own guns. The $0 tax did not loosen the background check; it only removed the fee.
A Form 4473 transfer is released once the NICS check and the dealer's process are complete. A voluntary Form 4 waits on ATF: For applications finalized in July 2026, ATF reported average processing times of 9 days for individual eForm 4 and 33 days for trust eForm 4. Individual waits can be longer. The individual eForm 4 median was 8 days in July 2026. Once the ATF approves your Form 4, you can take possession.
For a Form 4 filing, where you take possession depends on the service model you chose in Step 2. A local or kiosk-assisted dealer releases the suppressor after approval. A remote dealer may arrange delivery where state and federal rules allow it. Keep a copy of the approved Form 4 with the suppressor so you can produce it when required. Once it is in hand, the suppressor compatibility basics guide walks through mounting and tuning the host for the added backpressure. If the can is going on a pistol, the pistol suppressor setup guide covers the booster piston, fixed-barrel spacer, and suppressor-height sights that make a Glock or P320 run with a can.
For travel, ATF is not enforcing the NFA ban on moving unregistered items across state lines, and a suppressor needs no Form 5320.20. Destination-state law still applies, and ATF says it is unclear whether state courts will apply the 18 U.S.C. 926A transport safe harbor to an unregistered NFA item. If you hunt or compete in a state that ties possession to federal registration, register the can on a voluntary Form 4 before you go.
Suppressors are legal to own in 42 states. Eight states restrict or ban civilian suppressor ownership: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. If you live in one of those eight, the federal $0 tax does not help you, state law controls and a Form 4 will not clear you to possess a can there.
State law sits on top of the federal process, not under it. Even in the 42 legal states, confirm your county and city have no additional restrictions before you buy, and whether your state ties possession to federal NFA registration. ATF's October 2026 non-enforcement policy does not change state law, and neither Form 4473 nor Form 4 overrides a state or local ban.
You are responsible for complying with all federal, state, and local laws governing suppressor ownership, including NFA registration, transfer requirements, and state-level restrictions.

Suppressor buying in 2026 looks nothing like 2024: $0 federal tax, Form 4 approval no longer required federally, and a modern catalog of flow-through and HUB-standard cans. This hub explains what changed, what didn't, and which suppressors to start with by caliber.
One registered can that runs 9mm, 5.56, .300 BLK, and .308. We rank the true multi-caliber suppressors of 2026 and explain the bore-diameter, mount, and pressure tradeoffs that decide whether one can now beats dedicated cans later.
Florida's 2026 holiday runs September 1 through December 31 with no price caps and suppressors newly exempt. Here is what to buy first, ordered by dollar savings and commercial intent: suppressors, optics, magazines, then triggers, stocks, holsters, slings, and cleaning kits.
