Yes. Suppressors are still NFA items under federal law, sitting in the same regulatory category as machine guns, short-barreled rifles, and destructive devices. Owning one legally means registering it in a federal database, getting ATF approval, passing a background check, and submitting fingerprints and a passport-style photograph. A recent change to the tax code dropped the $200 transfer and making tax for suppressors to $0, but every other step in the registration process still applies.
How Federal Law Defines a Suppressor
Two statutes put suppressors under NFA control. The National Firearms Act includes “any silencer (as defined in section 921 of title 18, United States Code)” in its definition of “firearm.”1Office of the Law Revision Counsel. 26 U.S. Code 5845 – Definitions The Gun Control Act supplies the working definition: a “firearm silencer” or “firearm muffler” is any device that reduces the sound of a portable firearm, along with any combination of parts designed for assembling one and any part intended only for that purpose.2Office of the Law Revision Counsel. 18 U.S. Code 921 – Definitions
That last clause reaches further than most buyers expect. A suppressor tube without baffles, a set of baffles without a tube, or components marketed as “solvent traps” can each qualify as a silencer if the ATF finds they were designed or intended for suppressor assembly. The ATF has examined many solvent trap kits and classified them as silencers. Possessing one of those without NFA registration carries the same penalties as possessing an unregistered, fully assembled suppressor.
What NFA Classification Requires
Every NFA firearm in civilian hands has to appear in the National Firearms Registration and Transfer Record maintained by the ATF.3Office of the Law Revision Counsel. 26 U.S. Code 5841 – Registration of Firearms Suppressors, machine guns, short-barreled rifles, short-barreled shotguns, destructive devices, and “any other weapons” all live in the same framework under 26 U.S.C. Chapter 53.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act
In practice, that means you cannot walk out of a store with a suppressor the way you can with an ordinary rifle. Before any transfer, the ATF has to approve the paperwork, run the background check, and register the item to you. The dealer holds the suppressor until that approval comes through.
What Changed With the Tax, and What Did Not
For decades, acquiring any NFA item meant paying a $200 tax per item. Congress amended that. The transfer tax is now $200 only for machine guns and destructive devices; for every other NFA item, including suppressors, it is $0.5Office of the Law Revision Counsel. 26 U.S. Code 5811 – Transfer Tax The making tax follows the same split: $200 for machine guns and destructive devices, $0 for everything else.6Office of the Law Revision Counsel. 26 U.S. Code 5821 – Making Tax
Nothing else changed. You still file an application, still get fingerprinted, still submit a photograph, still wait for ATF approval, and still must be registered as the lawful possessor. Many online guides and dealer pages still describe a $200 suppressor tax stamp. Expect that outdated language to persist for a while.
Buying a Suppressor From a Dealer
Most people acquire a suppressor through a licensed dealer who holds a Federal Firearms License with a Special Occupational Tax status. The dealer walks the paperwork through ATF Form 4. Federal law requires the following before the transfer can be approved:7Office of the Law Revision Counsel. 26 U.S. Code 5812 – Transfers
- A written application on ATF Form 4, filed in duplicate, identifying both the buyer and the specific suppressor.
- Payment of any applicable tax before transfer. For suppressors this is currently $0.
- Fingerprints and a passport-style photograph, if you are registering as an individual.
- ATF approval and registration before you take possession. The dealer holds the item until that clears.
The ATF will deny an application if the transfer would put the buyer in violation of any law, including state laws that ban suppressor ownership. If you register through a trust or other legal entity, every responsible person associated with that entity must also submit fingerprints and a photograph. A responsible person generally means anyone who can direct the management or policies of the trust, which usually covers all trustees and sometimes the person who created it.
How Long Approval Takes
The ATF processes suppressor transfers electronically through its eForms system. As of February 2026, the ATF reports average processing times of roughly 10 days for individual eForm 4 applications and 26 days for trust-based eForm 4 applications.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times Those averages move with application volume and with whether an individual file needs extra research. Some approvals return in under a week; others stretch past a month.
Making Your Own Suppressor
You can legally make a suppressor for personal use, but ATF approval has to come first. The application is ATF Form 1 rather than Form 4. You identify yourself and the item you intend to make, including model, caliber, and a serial number you assign. Individuals submit fingerprints and a photograph, same as with a Form 4.9Office of the Law Revision Counsel. 26 U.S. Code 5822 – Making The application will be denied if making or possessing the suppressor would violate any law that applies to you.
Approval must be in hand before you drill, assemble, or otherwise create the suppressor. Buying suppressor parts and putting them together before your Form 1 is approved is a federal crime, even if you fully intend to register the finished item. The ATF has enforced this aggressively against solvent trap kits that are one drilling operation away from a functional suppressor.
Penalties for Skipping the Process
The NFA lists a dozen prohibited acts. The ones that catch suppressor owners most often are possessing an unregistered suppressor, possessing a suppressor that is not registered to you in the National Firearms Registration and Transfer Record, and making a suppressor without prior ATF approval.10GovInfo. 26 U.S. Code 5861 – Prohibited Acts Altering or removing a serial number and transporting an unregistered NFA item across state lines are also federal offenses under the same statute.
Any violation carries a maximum penalty of 10 years in federal prison, a fine of up to $10,000, or both.11Office of the Law Revision Counsel. 26 U.S. Code 5871 – Penalties The $0 tax made acquisition cheaper. It did nothing to the penalties for skipping the paperwork.
Traveling Across State Lines
Some NFA items require you to file ATF Form 5320.20 and get written approval before crossing state lines. That form covers destructive devices, machine guns, short-barreled rifles, and short-barreled shotguns.12Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Transport Interstate or to Temporarily Export Certain National Firearms Act Firearms Suppressors are not on the list. You can travel with a registered suppressor across state lines without notifying the ATF.
State law is the other half. Carrying a registered suppressor into a state that bans them is still a state-law violation, federal paperwork or not. Keep your approved Form 4 or Form 1 with the item when traveling; it is your proof of registration if a law enforcement officer asks.
What Happens When the Owner Dies
NFA items do not turn into contraband when the owner dies. An executor or personal representative can hold them during administration of the estate, kept secure and inaccessible to anyone else. To permanently transfer a suppressor to an heir named in the will, the heir files ATF Form 5 with a copy of the death certificate and documentation showing them as a lawful beneficiary. Transfers by bequest or inheritance are exempt from the transfer tax under federal law.13GovInfo. 26 U.S. Code 5852 – Transfer Tax Exemptions The heir still passes a background check and still ends up with the suppressor registered to them. Someone not named in the will who wants to acquire the item from the estate goes through the standard Form 4 process instead.
State Law Still Governs
Federal NFA compliance does not override state law. Roughly 42 states allow civilian suppressor ownership; eight prohibit it outright. Some states that allow ownership still restrict use for activities like hunting. Verify your state’s rules before you buy. A local dealer will usually know the restrictions, but the legal responsibility is yours.
If you move to a state that bans suppressors, you cannot bring your registered suppressor with you. The workable options are selling or transferring it to someone in a state where it remains legal, storing it with someone in such a state, or surrendering it. Moving with an NFA item you cannot lawfully possess in your new state creates a violation even though the item is federally registered.
