Firearms registry laws in the United States split three ways: federal law forbids a general registry of gun owners, a narrow federal registry does exist for a small category of heavily regulated weapons under the National Firearms Act, and a handful of states run their own registration systems. Which set of rules touches you depends on what you own and where you live.
The Federal Ban on a General Gun Registry
The Firearms Owners’ Protection Act of 1986 bars the federal government from building a searchable database of gun owners. Under 18 U.S.C. § 926, no federal regulation may require that dealer records be transferred to any government-controlled facility, and no system for registering firearms, firearm owners, or firearm transactions may be created.1Office of the Law Revision Counsel. 18 USC 926 – Rules and Regulations That prohibition covers the guns most Americans own: handguns, hunting rifles, shotguns, and modern sporting rifles that don’t fall under the National Firearms Act.
The federal system relies instead on a paper trail scattered across thousands of independent gun dealers. Every licensed dealer must keep ATF Form 4473 on file for at least 20 years after each sale, recording the buyer’s identity and the firearm’s details.2Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 478.129 – Record Retention Those records live at the dealer’s place of business, not in a government system. When a dealer goes out of business, the records ship within 30 days to the ATF’s Out-of-Business Records Center in Martinsburg, West Virginia, where they’re archived under the same restrictions that prevent them from becoming a searchable registry.3Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 478.127 – Discontinuance of Business
Why Tracing Isn’t the Same as a Registry
When police recover a firearm at a crime scene, the ATF’s National Tracing Center works down the distribution chain rather than looking the gun up in a database.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Tracing Center The manufacturer identifies which wholesaler received the gun, the wholesaler identifies the dealer, and the dealer checks their Form 4473 records for the original buyer. Each step is a separate contact, and a single trace can take days.
That design is intentional. The government can trace a specific gun when it has a reason to, but it cannot run broad queries like “show me every firearm registered to this person.” No instant lookup exists for the roughly 400 million firearms in private hands nationwide. In states that don’t require background checks on private sales, the paper trail may end at the original retail purchase, with no record of any later transfer.
The National Firearms Act Registry
The exception to the federal ban is the National Firearms Registration and Transfer Record, maintained by the ATF under 26 U.S.C. § 5841.5Office of the Law Revision Counsel. 26 USC 5841 – Registration of Firearms This is a real federal registry: it records every covered item by identification, date of registration, and the name and address of the person entitled to possess it. The covered category is narrow, defined under 26 U.S.C. § 5845:6Office of the Law Revision Counsel. 26 USC 5845 – Definitions
- Machine guns, meaning any weapon that fires more than one round per trigger pull
- Short-barreled rifles, with barrels under 16 inches or an overall length under 26 inches
- Short-barreled shotguns, with barrels under 18 inches or an overall length under 26 inches
- Silencers, meaning any device designed to muffle the sound of a firearm
- Destructive devices, including explosives, grenades, and firearms with a bore over half an inch (most shotguns excluded)
- Any other weapons, a catch-all for concealable firearms that don’t fit standard categories, such as pen guns or smooth-bore pistols
Every manufacturer, importer, and private maker must register each of these items, and every transfer to a new owner must be recorded.7Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 479.101 – Registration of Firearms Possessing an unregistered NFA item is a federal felony carrying up to ten years in prison.8Office of the Law Revision Counsel. 26 USC 5871 – Penalties The NFA itself caps the fine at $10,000, but the general federal sentencing statute allows fines up to $250,000 for any felony, which is the figure prosecutors typically cite.9Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine Each unregistered item counts as a separate offense.
How to Register an NFA Firearm
The process depends on whether you’re making a new NFA item or buying an existing one. If you’re building something yourself, such as assembling a short-barreled rifle from a standard rifle, you file ATF Form 1 (Application to Make and Register a Firearm).10Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Make and Register NFA Firearm, ATF Form 5320.1 If you’re buying from a dealer, the dealer files ATF Form 4 (Application for Tax Paid Transfer and Registration of a Firearm) on your behalf.11Bureau of Alcohol, Tobacco, Firearms and Explosives. eForms Applications Both forms can be filed through the ATF’s eForms portal or on paper.
Tax Stamp Costs
The transfer tax under 26 U.S.C. § 5811 is $200 for machine guns and destructive devices, and $0 for every other NFA firearm, including silencers, short-barreled rifles, short-barreled shotguns, and any-other-weapons.12Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax The making tax under 26 U.S.C. § 5821 follows the same split: $200 for machine guns and destructive devices, $0 for everything else.13Office of the Law Revision Counsel. 26 USC 5821 – Making Tax The tax is non-refundable and paid at the time of application. Once approved, the ATF issues a tax stamp that serves as proof of registration.
Required Documentation
Both Form 1 and Form 4 require detailed information about the firearm: manufacturer, model, caliber, barrel length, overall length, and serial number. On the personal side, you’ll provide your full legal name, address, date of birth, and (optionally, but recommended for faster processing) your Social Security number. Two sets of fingerprints on FBI Form FD-258 cards and a passport-style photograph must accompany the application.
You must also send a completed copy of the application to the chief law enforcement officer in your area, typically the local police chief or county sheriff. This is a notification only; the CLEO does not approve or deny the application.14Bureau of Alcohol, Tobacco, Firearms and Explosives. Open Letter to Chief Law Enforcement Officers
Registering Through a Gun Trust
Many NFA owners register items through a gun trust rather than as individuals, which simplifies sharing access among family members. Under ATF Rule 41F, every “responsible person” named in the trust, including trustees, grantors, and any beneficiary with authority to possess firearms on behalf of the trust, must individually undergo a background check, submit fingerprints, provide a photograph, and complete ATF Form 5320.23.15Bureau of Alcohol, Tobacco, Firearms and Explosives. Background Checks for Responsible Persons (Final Rule 41F) Each responsible person also sends a copy of that form to their local CLEO. Adding a new trustee later means repeating the process for the next NFA application.
Current NFA Processing Times
The gap between electronic and paper filing has narrowed considerably, and in some cases paper is actually faster. Based on ATF data for applications finalized in March 2026:16Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times
- Form 1 (making a new NFA item): 49 days via eForms, 64 days on paper
- Form 4 to an individual (buying from a dealer): 6 days via eForms, 30 days on paper
- Form 4 to a trust: 25 days via eForms, 20 days on paper
- Form 5 (tax-exempt transfer, such as inheritance): 1 day via eForms, 27 days on paper
These are averages. The ATF notes that individual applications may take longer due to additional research or spikes in volume. A few years ago, wait times commonly stretched past a year, so the current turnaround is a dramatic improvement. Filing through eForms is faster for most applicants, with the notable exception of trust-based Form 4 transfers, where paper edges ahead slightly.
State Registration Requirements
Most states do not require firearm registration, and some have passed laws specifically prohibiting local governments from creating registries. Fewer than ten states plus the District of Columbia maintain any form of registration system. The scope varies widely. A few require registration of all firearms, while others track only handguns or weapons classified as assault firearms under local definitions. Some states use their permitting system as a de facto registry by linking handgun serial numbers to individual licenses.
If you live in or move to a state with a registration requirement, the window for compliance is often short, sometimes as few as five days after acquiring a firearm or bringing one into the state. Missing the deadline can bring criminal charges. State registration forms typically ask for the same core information as federal forms, including firearm make, model, serial number, caliber, and the owner’s personal identification. Some also require proof of residency or completion of a safety course. Administrative fees where they exist are generally modest, though certain cities impose substantially higher fees than the statewide baseline.
Owners who move between states face the most practical risk. A firearm that requires no registration in one state may need to be registered within days of crossing the border into another. Before relocating, check the specific requirements of your destination state and any municipality within it, because city-level rules sometimes go beyond what the state requires.
Registration Status After a Loss, Death, or Move
A few situations put an owner’s registration status in question and are worth flagging.
If a registered NFA item is lost or stolen, the registered owner must report it to the ATF immediately upon discovering the loss, with no grace period. The report must include the owner’s name and address, the firearm’s type, serial number, model, caliber, and manufacturer, along with the date, location, and circumstances of the theft or loss.17Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 479.141 – Stolen or Lost Firearms
When an NFA owner dies, the executor or trustee has a reasonable window, generally before probate closes, to arrange proper transfers. A lawful heir can receive registered items tax-free using ATF Form 5, though the heir still needs to submit fingerprints and pass a background check.18Bureau of Alcohol, Tobacco, Firearms and Explosives. Transfers of National Firearms Act Firearms in Decedents’ Estates Any unregistered NFA items found in an estate are contraband; the executor cannot register them after the fact and should contact the local ATF office to arrange surrender.
Interstate travel with a machine gun, destructive device, short-barreled rifle, or short-barreled shotgun requires prior written ATF authorization on Form 20 under 18 U.S.C. § 922(a)(4).19Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Silencers and any-other-weapons are not listed in that section and do not require Form 20, though they still need to be legal at the destination.
