Confirm fit, state law, manufacturer coverage, dealer participation, ownership, and travel before choosing the injunction-covered Form 4473 path or the traditional $0-tax Form 4.

Buying a suppressor now starts with a path choice. Confirm the can, state, dealer, ownership method, and travel plan before you use Form 4473 or file the traditional $0-tax Form 4.
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.
Most purchases still use the Form 4 process below. One exception: a federal judge struck down NFA registration for suppressors and SBRs on August 5, 2026 in Silencer Shop Foundation v. ATF, and the first transfers with no Form 4 ran at 12:01 a.m. on August 13. SilencerCo made that path concrete on August 31 by listing 27 states where a participating dealer may transfer a qualifying new SilencerCo suppressor on Form 4473 and NICS. That removes Form 4, fingerprints, a passport photo, CLEO notice, and the separate ATF pre-approval wait for that transaction. Coverage remains party-specific, not nationwide; our current Form 4 coverage article explains the boundaries, and the transfer-path checker tests the manufacturer, state, dealer, transaction, ownership, and travel factors together. The suppressor buying guide ranks cans by caliber; the suppressor compatibility basics guide covers thread, mount, and over-gassing.
The largest open question is travel. SilencerCo says interstate treatment of suppressors acquired through its Form 4473 process remains unresolved and strongly encourages buyers to keep them in the purchase state. It recommends the traditional $0-tax Form 4 for trusts and for buyers who travel, hunt, or compete out of state.
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 on one stamp, and a rimfire can is the cheapest way to learn the NFA process. 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 pistol and PCC hosts, best .300 Blackout suppressors the subsonic crowd, best .300 Win Mag suppressors the magnum-rated cans, best .22 suppressors rimfire first stamps, best multi-caliber suppressors the one-can picks from 9mm to .308, and best shotgun suppressors the six choke-mounted 12-gauge cans.
Ask the transferring dealer which process applies before you order. A qualifying new SilencerCo suppressor may use Form 4473 and NICS in one of the company's 27 listed states, but only when the dealer participates and the product moved through SilencerCo or an authorized distributor. B&T USA, plaintiff-organization membership, and other manufacturer programs need their own coverage confirmation. SilencerCo's state list is not universal.
If the Form 4473 path does not fit, choose the Form 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 traditional 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.
If you want trust or entity ownership, use the Form 4 path. SilencerCo recommends the established registration process for trusts rather than treating a Form 4473-only purchase as a substitute for the trust's ownership and responsible-person structure.
| 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 that $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, moving a can from an estate to an heir requires a tax-free ATF Form 5 and ATF approval before the heir can take it. Solo owners with no shared-possession or inheritance plans should file as an individual and save the trust drafting fee.
Use Form 4473 only when the exact purchase is injunction-covered, state law allows it, and the dealer confirms participation. Every dealer transfer still includes Form 4473 and a NICS background check. A qualifying SilencerCo transfer does not add Form 4, fingerprints, a passport photo, CLEO notification, or a separate ATF approval wait.
Use eForm 4 for every uncovered transfer, trust purchase, or plan that includes interstate travel. The dealer starts the application and you certify your section. The federal transfer tax was eliminated for suppressors. 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. If you are buying a finished can off the shelf outside a confirmed Form 4473 pathway, Form 4 is your path. If you are leaning toward making one instead, 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 identical Form 4 and eForm process for those builds.
A 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 qualifying 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 and documents that show the product and transaction were covered.
The CLEO notification is still required as of mid-2026. The ATF published a proposed rule in May 2026 to remove the CLEO notification requirement (RIN 1140-AA65), with a public comment period that closes July 6, 2026. That is a proposed rule, not a final one. Until the ATF publishes a final rule, you still send the CLEO copy as part of your Form 4. Do not skip it on the assumption that it has already gone away, because it has not.
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.
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.
Where you take possession depends on the Form 4 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 a qualifying Form 4473 transfer, the dealer may release the can after the required background check and store process are complete. Keep it in the purchase state while interstate treatment remains unresolved. If you expect to travel, hunt, or compete out of state, use the Form 4 route before taking possession.
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 file. SilencerCo's 27-state pathway is not the same thing as the 42-state possession map: manufacturer coverage and state legality answer different questions. 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 for most buyers, 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.
