Yes, suppressors are legal in Louisiana. The state adds nothing on top of federal law: no state permit, no waiting period, no registration beyond what the ATF already requires. And as of January 1, 2026, the federal transfer tax for suppressors dropped from $200 to $0, so the paperwork is still mandatory but the cost is not. You buy through a federally licensed dealer, pass a background check, and wait for ATF approval.
State Law and Local Preemption
Federal law treats a suppressor as an NFA “firearm,” which triggers registration through the Bureau of Alcohol, Tobacco, Firearms and Explosives.1Office of the Law Revision Counsel. 26 U.S. Code 5845 – Definitions Louisiana layers nothing on top. Meet the federal requirements and you’re legal in every parish.
Cities and parishes can’t change that. Louisiana Revised Statute 40:1796 preempts any political subdivision from enacting rules more restrictive than state law on firearms, ammunition, components, or firearms accessories, and suppressors fall inside that protection. Any local ordinance that tries to go further is void, and affected gun owners can sue for declaratory and injunctive relief plus attorney fees.2Louisiana State Legislature. Louisiana Revised Statutes 40:1796 – Preemption of State Law
How to Buy One
Every purchase runs through a federally licensed dealer with an SOT. You can’t buy from a private seller or an online vendor without a dealer handling the transfer.
- Pick your suppressor and pay the full purchase price at the dealer, or have one shipped to your local dealer from an online retailer.
- Complete ATF Form 5320.4, the application to transfer and register an NFA firearm. Individual applicants submit fingerprints and a photograph.3Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Application to Transfer and Register NFA Firearm (Tax-Paid) – ATF Form 5320.4
- Forward a completed copy to your local chief law enforcement officer. This is notification only. The CLEO cannot approve or deny.4Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Background Checks for Responsible Persons (Final Rule 41F)
- Wait for the ATF background check. Once approved, the Form 4 comes back to your dealer, who releases the suppressor.
The $0 Tax Stamp
Effective January 1, 2026, the federal transfer tax for suppressors is $0. The $200 NFA transfer tax now applies only to machine guns and destructive devices. Suppressors, short-barreled rifles, and short-barreled shotguns all transfer tax-free.5Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax This is a permanent statutory change, not a temporary waiver. The Form 4 and background check still apply.
How Long the Wait Takes
The multi-month Form 4 backlog is largely gone. As of February 2026, ATF reports average processing times of 10 days for individual eForms, 21 days for individual paper filings, 26 days for trust eForms, and 24 days for trust paper filings.6Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Current Processing Times These are averages. Some applications take longer when the background check needs additional research or when submission volume spikes.
Individual Registration or an NFA Trust
You can register a suppressor to yourself or to a gun trust. Both are legal in Louisiana. The choice affects who else can lawfully possess the item and what happens when you die.
Under individual registration, only the registered owner can legally possess the suppressor. Handing it to a friend at the range or leaving it with a gunsmith while you travel creates a legal gray area. A trust names multiple responsible persons, and each of them can possess the suppressor without the owner present. A trust also lets you designate successor trustees who take over when you die, avoiding the Form 5 process heirs face with individually registered items.
The tradeoff is paperwork. Under the ATF’s 41F rule, every responsible person on the trust must submit fingerprints on two FD-258 cards, attach a photograph to a completed Form 5320.23, undergo a background check, and send a copy of Form 5320.23 to their local chief law enforcement officer.4Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Background Checks for Responsible Persons (Final Rule 41F) A trust with six co-trustees generates six times the paperwork per purchase.
Who Cannot Own a Suppressor
Federal law under 18 U.S.C. § 922(g) prohibits several categories of people from possessing any firearm or ammunition, and that includes suppressors:
- Anyone convicted of a crime punishable by more than one year of imprisonment
- Fugitives from justice
- Unlawful users of a controlled substance, including anyone addicted to one
- Anyone adjudicated as mentally defective or committed to a mental institution
- Undocumented immigrants
- Anyone discharged from the military under dishonorable conditions
- Anyone who has renounced U.S. citizenship
- Anyone subject to a court order restraining them from harassing, stalking, or threatening an intimate partner or their child
- Anyone convicted of a misdemeanor crime of domestic violence
Anyone under indictment for a crime punishable by more than one year of imprisonment is also barred from shipping, transporting, or receiving firearms or ammunition.7Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Identify Prohibited Persons Registration doesn’t cure prohibited status. Possession by a prohibited person is a separate federal crime.
Penalties for Unregistered Possession
Possessing an unregistered suppressor is a federal felony. Under 26 U.S.C. § 5871, the NFA authorizes fines up to $10,000 and imprisonment up to 10 years.8Office of the Law Revision Counsel. 26 U.S. Code 5871 – Penalties The general federal sentencing statute, 18 U.S.C. § 3571, allows fines up to $250,000 for any felony conviction, and courts routinely apply the higher figure.9Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine
You do not need a fully assembled suppressor to face charges. Federal prosecutors can pursue constructive possession, meaning you knowingly had the ability and intent to assemble a suppressor from parts on hand. A solvent trap kit paired with an adapter that threads onto your barrel can be enough, depending on the circumstances. The test is whether you had the parts and the intent, not whether the device was assembled.
Once you own a registered suppressor, keep proof of registration available for any ATF officer who asks.10Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Application to Make and Register NFA Firearm (ATF Form 5320.1) Instructions Many owners keep a digital copy of the approved Form 4 on their phone.
Hunting With a Suppressor
Louisiana explicitly allows it. Under RS 56:116.6, anyone authorized to possess a suppressor, evidenced by the required federal tax stamp, may use a suppressed firearm to take game birds, wild quadrupeds, outlaw quadrupeds, nutria, and beaver.11Louisiana State Legislature. Louisiana Revised Statutes 56:116.6 – Sound Suppressors
Using a suppressor to hunt without proper federal authorization is a class six violation under state wildlife law. The penalty is a fine between $900 and $950, up to 120 days in jail, and forfeiture of anything seized in connection with the violation.12Justia. Louisiana Revised Statutes 56:36 – Class Six Violation That’s on top of any federal charges for the unregistered item itself.
One federal boundary applies to migratory birds. Federal regulations prohibit rifles and pistols for taking migratory game birds, so a suppressed rifle or pistol cannot be used for ducks, geese, doves, and similar species. The suppressor isn’t the problem. The firearm platform is.
Traveling Out of State
Suppressors are among the easier NFA items to travel with. Unlike short-barreled rifles, short-barreled shotguns, and machine guns, they do not require prior ATF approval on Form 5320.20 before crossing state lines. You can transport a registered suppressor interstate with no additional paperwork.
Your destination has to allow them. As of 2026, eight states still ban civilian suppressor possession outright. Verify the law before you drive through or visit. A Louisiana registration will not protect you from a state that prohibits the item.
Passing One On When You Die
A suppressor does not automatically transfer to next of kin. The executor or administrator of the estate files ATF Form 5320.5 to transfer the item to a lawful heir. The transfer is tax-exempt, the heir pays nothing, and no dealer is needed.
Form 5 requires the decedent’s name, address, and date of death, along with documentation showing the heir’s legal entitlement. The executor signs the form and the ATF processes the transfer. If the heir is a prohibited person, the transfer is denied.13Bureau of Alcohol, Tobacco, Firearms and Explosives. Application for Tax Exempt Transfer and Registration of Firearm (ATF Form 5)
Until Form 5 is approved, the suppressor should stay in the possession of the estate, not the heir. Handing it over before the paperwork clears puts the heir in possession of an unregistered NFA firearm. The ATF recommends that executors contact the NFA Division early in the process. The Division can be reached at (304) 616-4500 or NFAFAX@ATF.GOV.
