Yes, every suppressor you own needs its own tax stamp — meaning its own separate ATF registration tied to that specific serialized device. What has changed is the price: under current federal law, the tax on a suppressor transfer or making is $0, not the familiar $200. The paperwork is still per-item, but the per-item fee is gone.
Every Suppressor Is Registered Individually
Federal law treats each suppressor as its own firearm. The National Firearms Act defines “firearm” to include “any silencer,” placing suppressors in the same regulatory category as short-barreled rifles, machineguns, and destructive devices.1Office of the Law Revision Counsel. 26 USC 5845 – Definitions Because each suppressor is a distinct firearm with its own serial number, each must be registered separately in the National Firearms Registration and Transfer Record.2Office of the Law Revision Counsel. 26 USC 5841 – Registration of Firearms
There is no bulk registration, no multi-item form, and no volume discount. Own five suppressors, hold five approved forms. Each registration ties a specific serialized device to you by name and address, and the ATF keeps that record indefinitely.
Why the Tax Is Now $0
For decades, every suppressor transfer or build carried a $200 federal tax, a figure unchanged since the NFA passed in 1934. Under current law, the $200 transfer tax applies only to machineguns and destructive devices. For any other NFA firearm, suppressors included, the transfer tax is $0.3Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax The same change applies to the making tax if you build your own suppressor on a Form 1; that tax is also $0 for anything other than a machinegun or destructive device.4Office of the Law Revision Counsel. 26 USC 5821 – Making Tax
People still say “tax stamp” out of habit, and the ATF’s approval process is otherwise unchanged. You file the application, submit fingerprints, pass a background check, and wait for approval before taking possession. The per-suppressor paperwork is identical. The per-suppressor fee is zero.
What You Still File for Each One
The form depends on how you acquire the suppressor. Buying from a licensed dealer means ATF Form 4. Building your own means ATF Form 1. Both require your full legal name and address, the suppressor’s manufacturer, model, and serial number, two passport-style photographs, and two FBI fingerprint cards (Form FD-258).5Office of the Law Revision Counsel. 26 USC 5812 – Transfers
Applications go through the ATF’s eForms online portal, where you create an account and submit everything digitally.6Bureau of Alcohol, Tobacco, Firearms and Explosives. eForms Applications Profile information must match your application documents exactly; mismatches cause delays. You must also notify your local Chief Law Enforcement Officer as part of the filing. The ATF then runs the background check and reviews the application. You cannot take possession until your form is approved.5Office of the Law Revision Counsel. 26 USC 5812 – Transfers
Every suppressor you add means another full application cycle. The forms are the same, the fingerprints are the same, the wait is the same. Just no $200.
How Long Approval Takes Now
Wait times have dropped sharply with eForms. The ATF’s most recently published figures show Form 4 applications filed electronically by individuals averaging around 10 days, and Form 4 applications filed through a trust averaging around 26 days.7Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times Those numbers fluctuate, and the ATF updates them periodically. Anyone who remembers six-month or year-long paper waits is working from an outdated picture.
Transfers and Second Owners
A suppressor registration is not transferable. When you sell or gift a suppressor, the new owner files their own Form 4, passes their own background check, and waits for their own ATF approval before taking possession.5Office of the Law Revision Counsel. 26 USC 5812 – Transfers Until that approval comes, the suppressor stays with the seller or at the dealer’s location. The process mirrors a new purchase.
With the transfer tax at $0, the financial side of changing hands is now limited to the sale price, any dealer transfer fee, and fingerprinting costs.3Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax
Inheriting a Suppressor
If a suppressor owner dies, the device can pass to an heir or estate beneficiary using ATF Form 5, a tax-exempt transfer specifically for items moving through an estate.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Transfer and Register NFA Firearm Tax-Exempt – ATF Form 5320.5 The beneficiary still needs ATF approval and must not be a prohibited person, but no tax is owed regardless of item type. This is one of the few situations where an NFA item changes hands outside the standard Form 4 process.
State Laws and Travel Still Matter
Federal registration is only half of what governs ownership. Roughly eight states ban private suppressor ownership entirely, and several more prohibit using suppressors while hunting even where ownership is legal. Confirm your state permits civilian possession before you start any federal application. State laws change, so check current law rather than any static list.
Interstate travel with a suppressor does not require ATF permission. Several categories of NFA firearms — machineguns, short-barreled rifles, short-barreled shotguns, and destructive devices — require ATF Form 5320.20 and prior approval before crossing state lines.9Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF Form 5320.20 – Application to Transport Interstate Suppressors are not on that list. Still, carrying a properly registered suppressor into a state that bans them is a state crime no matter what your federal paperwork says. Keep a copy of your approved registration with the suppressor whenever you travel.
What Happens If You Skip the Registration
Possessing a suppressor that is not registered to you in the National Firearms Registration and Transfer Record is a federal felony.10Office of the Law Revision Counsel. 26 USC 5861 – Prohibited Acts A conviction carries up to a $10,000 fine, up to ten years in prison, or both.11Office of the Law Revision Counsel. 26 USC 5871 – Penalties Because the maximum sentence exceeds one year, a conviction also permanently bars you from possessing any firearm or ammunition under federal law.12Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
The same rule applies to unassembled parts. If you possess components with no lawful purpose other than building a suppressor, such as certain thread adapters or drilled solvent trap kits, federal prosecutors can pursue a constructive possession theory. Having everything needed to assemble an unregistered suppressor, with no legal reason to own those parts separately, is treated as possession of the finished device. This is where people most often slip into felony territory without realizing it.
Penalties are the same whether you built, bought, or inherited the unregistered item. With the tax at $0 and approvals measured in days, the old cost-and-wait argument for cutting corners has largely disappeared. Each suppressor still needs its stamp. The stamp just no longer costs anything.
