At a Glance: Selling firearms legally comes down to two paths: selling as a licensed dealer or selling as a private individual. A licensed dealer runs every sale through a background check and federal paperwork, no matter where the sale starts. A private seller has narrower options and is bound by both federal and state law. The sales channel, online or in-store, does not change the legal core. What changes the rules is who is selling, who is buying, and where the buyer lives. This guide walks through both paths, the federal laws behind them, a 2026 update to firearm dealer licensing, and how dealers keep every firearm sale compliant.
How Do You Sell Firearms Legally?
To sell firearms legally, you either hold a Federal Firearms License and run each sale through a background check and recordkeeping, or you make an occasional private sale within the limits federal and state law allow. Anyone in the business of selling firearms for profit must be licensed. Every commercial firearm sale, online or in person, ends with a licensed dealer completing an ATF Form 4473 and a background check before the buyer takes the gun.
Here is the difference between the two paths at a glance:
| Factor | Licensed Dealer (FFL) | Private Seller |
|---|---|---|
| Who it covers | Anyone engaged in the business of selling firearms | An individual making an occasional sale from a personal collection |
| Background check | Generally required on every transfer through NICS | Federal law generally does not require a background check for a lawful private, in-state transfer, but state or local laws may require one. |
| Form 4473 and bound book | Required and retained | Not required under federal law for a same-state transfer between two unlicensed individuals. State or local rules may still apply. |
| Out-of-state buyers | Ship to an FFL in the buyer’s state for transfer | Cannot sell directly across state lines; must route through an FFL |
| Selling to a prohibited person | Prohibited, with mandatory screening | Prohibited if the seller knows or has reasonable cause to believe |
The rest of this guide breaks down each path so you can find where your situation fits.
Do You Need a License to Sell Firearms?
You need a Federal Firearms License if you are engaged in the business of dealing in firearms, which federal law defines under 18 U.S.C. § 921(a)(21)(C). The Bipartisan Safer Communities Act of 2022 describes that as devoting time, attention, and labor to dealing in firearms to predominantly earn a profit through repeated purchase and resale. Selling a few guns from a personal collection is generally not considered dealing. Buying and reselling firearms for profit regularly is illegal, and doing it without a license can carry up to five years in prison.
The line between a private seller and an unlicensed dealer has been in motion. ATF issued a 2024 regulation that added examples and presumptions to the “engaged in the business” definition, but federal courts have since vacated those regulatory provisions, and in May 2026, ATF proposed formally rescinding them while keeping the statutory definition Congress wrote. The current status is tracked on the ATF rule page. Because the test is fact-specific and still developing, confirm your situation with the ATF or qualified counsel before you start selling. This article is general information, not legal advice.
If you plan to sell firearms as a business, you apply for a license through the Bureau of Alcohol, Tobacco, Firearms and Explosives. A standard Type 01 dealer license, used by a gun shop or a pawn shop that handles firearms, costs $200 for three years.
Selling as a Licensed Dealer: The In-Store Process
A licensed dealer follows the same process on every sale: verify the buyer, run a background check, complete the Form 4473, hand over the firearm only after a process, and record the transaction. This sequence applies to a first-time buyer and a repeat customer alike, and it is the backbone of legal firearm transactions in the United States.
Run the background check
A federal firearms licensee must run a NICS background check on the prospective purchaser before transferring a firearm, under 18 U.S.C. § 922(t). The buyer fills out the Form 4473, and you submit the check through the National Instant Criminal Background Check System. A proceed clears the sale. A denial stops it. This screening is the federal system’s frontline tool for public safety in firearm sales. You also confirm the buyer meets the federal age minimums for a licensee sale: 18 for a long gun and 21 for a handgun.
Keep accurate records
Every firearm a dealer acquires or sells goes into the acquisition and disposition record, the bound book, with the make, model, serial number, and the parties involved. Under ATF Ruling 2021R-05F, both A&D records and Form 4473s must be retained for the life of the FFL, until business or licensed activity is discontinued. Paper records older than 20 years may be moved to a separate warehouse, but they remain subject to ATF inspection. Accurate records are what let ATF and law enforcement trace a firearm and what protect your license during an inspection. A dealer who sells two or more handguns to the same potential buyer within five business days also files a multiple sale report with the ATF.
Refuse prohibited persons
It is unlawful to sell or deliver a firearm to anyone you know or have reasonable cause to believe is a prohibited person, under 18 U.S.C. § 922(d). Federal law in 18 U.S.C. § 922(g) lists who cannot receive or possess a firearm, including a person with a felony conviction, an unlawful user of a controlled substance, and a person under certain domestic violence orders. A straw purchase, where a buyer is secretly acquiring the firearm for someone else, is also a federal crime.
Selling Firearms Online
Selling firearms online is legal, but the internet is a sales channel, not a transfer method. A buyer can order online, yet the firearm never ships directly to that private individual. It ships to a licensed dealer near the buyer, who completes the Form 4473 and the background check before handing it over. This holds true on your own store site and on marketplaces like GunBroker.
Payment processing is a common snag, since many mainstream processors restrict firearm sales and can suspend accounts without warning. A firearm-friendly setup keeps checkout running. Gearfire’s eCommerce platform routes each order to the buyer’s chosen FFL and validates the license at checkout, paired with firearm-friendly payment processing built for the industry.
Private Sales: What Individuals Can and Cannot Do
A private seller may sell a firearm to a resident of their own state, as long as they are not engaged in the business and do not know or have reasonable cause to believe the buyer is prohibited. Federal law does not require an FFL to facilitate a lawful transfer between two unlicensed residents of the same state, though state or local laws may add requirements. It never allows a sale to a prohibited person, and it does not allow a private firearm sale directly across state lines.
A few rules govern every private transaction:
- Same-state buyers only, without a dealer. A private seller cannot sell directly to a resident of another state. That sale has to go through an FFL in the buyer’s state, who runs the check and completes the transfer.
- No sales to prohibited persons. The reasonable cause standard in 18 U.S.C. § 922(d) applies to private sellers too. If you suspect the buyer cannot legally own a firearm, do not sell.
- Keep a record. Federal law does not require a bill of sale for a private transaction, but a written bill of sale with the date, the parties, and the firearm details protects the seller.
Many private sellers choose to run the deal through a local gun shop for a small fee, so a background check is on record. In states with universal background check laws, that step is not optional.
State Laws Add Requirements
State law layers on top of federal law, and it often goes further. Before any firearm sale, check the rules in your state, because state legal requirements vary widely, and a legal transaction federally can still be illegal locally. The ATF state laws reference is a starting point, and your state attorney general’s office has the current details.
State law is the area where sellers get caught off guard most often, so treat it as a required check, not an afterthought.
Special Categories: NFA Items, Consignment, and Pawn
Some sales follow extra rules on top of the standard process. The most regulated items are those under the National Firearms Act, such as machine guns, short-barreled rifles, short-barreled shotguns, and suppressors. These require an ATF Form 4 transfer, registration, fingerprints, a background check, and ATF approval before the item changes hands. As of January 1, 2026, the federal making and transfer tax for NFA firearms other than machine guns and destructive devices was reduced to $0, though the registration and approval process still applies.
Consignment and pawn sales follow the standard dealer rules at the point of transfer. When a dealer sells a firearm on consignment for an owner, or sells a forfeited pawn item, the dealer still completes a Form 4473 and a background check with the buyer and logs the firearm in the bound book. A consignment sale does not skip any compliance step. It simply changes who originally owned the firearm.
Sell Firearms Online and In Store With Gearfire
The hardest part of selling firearms legally is not knowing the rules. It is applying them to every single transaction without a gap. A missed background check, a 4473 with a blank field, or a firearm that never made it into the bound book is what turns a normal sale into a violation. Running the business on one connected system removes most of that risk.

FAQs About Selling Firearms Legally
Do I need a license to sell my own guns?
Generally, no, if you are making an occasional private sale from a personal collection to a resident of your own state, and the buyer is not prohibited. You need a Federal Firearms License if you are engaged in the business of selling firearms to predominantly earn a profit. The line is fact-specific, so confirm your situation with the ATF or an attorney.
Can I sell a firearm to someone in another state?
Not directly. A private seller cannot transfer a firearm across state lines to another private individual. The firearm must go to a licensed dealer in the buyer’s state, who completes the Form 4473 and the background check before the buyer takes possession.
Is selling firearms online legal?
Yes. Online is a sales channel, not a transfer method. The buyer can order and pay online, but the firearm ships to a licensed dealer near the buyer, who runs the background check and completes the transfer in person. A firearm never ships directly to a private buyer.
Do private sellers have to run a background check?
Federal law does not require a background check on most private intrastate sales, but many states do require one, usually through a licensed dealer. A private seller may never sell to someone they know or have reasonable cause to believe is a prohibited person. Always check your state law.
Who is a prohibited person?
Under 18 U.S.C. § 922(g), a prohibited person includes someone with a felony conviction, an unlawful user of a controlled substance, and a person subject to certain domestic violence orders, among others. Selling or delivering a firearm to a prohibited person is a federal crime.
What records does a dealer keep on a firearm sale?
A licensed dealer completes a Form 4473 for each transfer and records the firearm in the acquisition and disposition bound book, including the serial number and the parties involved. Under ATF Ruling 2021R-05F, these records must be retained for the life of the FFL, with paper forms over 20 years old eligible for off-site warehouse storage that remains subject to ATF inspection.
