There is no federal limit on how many suppressors you can own. The National Firearms Act regulates each suppressor individually through registration and, until recently, a transfer tax, but the statute says nothing about a ceiling on collections. If you clear the eligibility requirements and live in a state that allows civilian ownership, you can register one suppressor or fifty. The real constraints are the per-item paperwork, your state’s laws, and the storage arrangements you set up at home.
No Federal Limit on Quantity
The National Firearms Act classifies suppressors as “firearms” alongside machine guns and short-barreled rifles.1Office of the Law Revision Counsel. 26 U.S. Code 5845 – Definitions Each one must be entered in the National Firearms Registration and Transfer Record and tied to a specific lawful owner.2GovInfo. 26 U.S. Code 5841 – Registration of Firearms As long as every suppressor in your possession has an approved registration in your name, or in the name of a trust or entity you control, you are within the law. Shooters who run different calibers routinely own several because a single can rarely fits every host firearm well.
State Bans That Override the Federal Rule
Federal permission doesn’t help if your state prohibits ownership. Eight states and the District of Columbia ban civilian possession outright: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. In those jurisdictions the answer to “how many” is zero, no matter how carefully you follow the NFA process.
Among the 42 states that allow ownership, Connecticut is the notable outlier: you can legally own a suppressor there but cannot use it for hunting. The other 41 states permit both ownership and hunting use, though specific game rules can apply. Local ordinances sometimes add requirements on top of federal law, so confirm your jurisdiction’s rules before you buy.
Who Is Eligible to Own One
Suppressors are firearms for purposes of the federal prohibitor list, so the same disqualifications that block someone from owning a rifle block them from owning a suppressor.3Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts You cannot legally own one if any of the following applies to you:
- A felony conviction, meaning any crime punishable by more than one year in prison, whatever the actual sentence.
- A misdemeanor domestic violence conviction, which is a permanent bar.
- An active restraining order protecting an intimate partner or their child.
- Unlawful use of or addiction to a controlled substance. Federal law still treats marijuana as a controlled substance even in states that have legalized it.
- A court finding of mental incompetence or an involuntary commitment to a mental institution.
- A dishonorable discharge from the military.
- Fugitive status.
- Renunciation of U.S. citizenship, and most nonimmigrant visa categories.
If you use an NFA trust, every “responsible person” listed on the trust must independently clear these requirements, submit fingerprints and a photograph, and pass a background check.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act (NFA) Responsible Person Questionnaire A prohibited person on a trust doesn’t create a workaround. It just gets the application denied.
What Each Additional Suppressor Costs You in Time and Paperwork
The reason “how many” is really a question about process is that every suppressor goes through its own approval. Five suppressors means five applications, five background checks, and five approvals. Here is what each purchase involves:
- You buy from a Federal Firearms Licensee who holds a Class 3 Special Occupational Tax license. The dealer keeps the suppressor until the ATF approves the paperwork. Processing fees at the dealer typically run $25 to $100 on top of the suppressor’s price.
- The dealer files ATF Form 4 (Application for Tax Paid Transfer and Registration of Firearm) on your behalf. The application identifies you with fingerprints and a passport-style photograph.5Bureau of Alcohol, Tobacco, Firearms and Explosives. eForms Applications6Office of the Law Revision Counsel. 26 U.S. Code 5812 – Transfer of Firearms
- You pay the federal transfer tax. As of 2026, the tax on suppressor transfers is $0. Recent changes to 26 U.S.C. ยง 5811 set the $200 rate only for machine guns and destructive devices, so suppressors now transfer at a $0 rate.7Office of the Law Revision Counsel. 26 U.S. Code 5811 – Transfer Tax
- The ATF runs a background check through NICS and, once approved, issues a tax stamp for that specific suppressor. The dealer then releases it.
Timing depends heavily on how you file. As of February 2026, the ATF reported average Form 4 processing times of 10 days for individual eForm 4 filings, 26 days for trust eForm 4 filings, 21 days for paper Form 4 individual filings, and 24 days for paper Form 4 trust filings.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times These averages shift month to month, but the electronic route is consistently faster, and there is little reason to file on paper.
Individual Registration vs. an NFA Trust
You can register each suppressor to yourself as an individual, to an NFA trust, or to a legal entity such as a corporation. For someone who owns a single suppressor and doesn’t plan to share it, individual registration is the simpler path. Once you’re building a collection, or you want a spouse or adult child to be able to use a suppressor without you standing beside them, a trust becomes the more useful structure.
An NFA trust is a legal document that names “responsible persons” who may lawfully possess the items registered to it. Each responsible person submits fingerprints, a photograph, and a background check when the trust acquires a new NFA item.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act (NFA) Responsible Person Questionnaire That extra paperwork is the price of the flexibility. When a suppressor is registered to you individually, no one else may possess it outside your direct supervision. Hand your suppressor to a friend at the range and walk away, and that friend is in illegal possession of an unregistered NFA firearm.
Storing Multiple Suppressors Without Creating a Constructive Possession Problem
Owning several suppressors introduces a storage issue most people don’t think about until it becomes one. Only the registered owner, or a responsible person on the trust, may possess an NFA firearm. Possession isn’t limited to physical handling. If someone in your household has unsupervised access to the safe where your suppressors sit, the ATF could treat that as constructive possession, which amounts to an unlawful transfer.
The practical fix is simple: store suppressors so that only you, or authorized trust members, can open the safe. A combination or key that no one else in the house knows or has is the standard approach. This matters most for people with roommates, adult children living at home, or a spouse who is not named on the trust.
Passing Suppressors to Heirs
Suppressors don’t disappear from the NFA registry when the owner dies. Federal law lets a lawful heir receive an NFA firearm without paying the transfer tax, as long as the executor files the correct paperwork and the heir is not a prohibited person.9GovInfo. 26 U.S. Code 5852 – Certain Transfers The heir still has to register the suppressor in their own name through the ATF. The tax exemption does not eliminate the registration requirement. For individually registered suppressors, the executor files an ATF Form 5 (tax-exempt transfer to a lawful heir). Skipping that step leaves the heir holding a suppressor registered to someone else, which is illegal under the NFA.
Trust registration changes the picture. The trust itself owns the items, so when the settlor dies, co-trustees or successor trustees named in the document continue to possess them without filing new ATF transfer paperwork. That continuity is one of the strongest reasons to use a trust when you plan to pass a collection down.
Penalties for Getting It Wrong
NFA violations are not calibrated to how minor the underlying mistake feels. Possessing an unregistered suppressor, failing to pay a required tax, or transferring one outside proper channels are all federal crimes.10Office of the Law Revision Counsel. 26 U.S. Code 5861 – Prohibited Acts A conviction carries up to 10 years in prison and a fine of up to $10,000.11Office of the Law Revision Counsel. 26 U.S. Code 5871 – Penalties
If an unregistered suppressor is used during a violent crime or drug trafficking offense, the penalties climb sharply: a mandatory minimum of 30 years in prison, with a possible life sentence for a second offense, and those terms run consecutively to any sentence for the underlying crime.12Office of the Law Revision Counsel. 18 U.S. Code 924 – Penalties The registration process is not optional, and the point at which those penalties attach is the moment of unregistered possession, not any later act.
