Selling a gun privately is legal in the United States under federal law — but the full picture is more nuanced than a simple yes or no. Depending on where you live, a perfectly legal private sale in one state can require extra steps just across the border. If you’ve searched “is it legal to sell a gun privately” and gotten conflicting answers, it’s because the law operates on two levels: federal and state.
What Federal Law Says About Private Gun Sales
Under the Gun Control Act of 1968, individuals who are not “engaged in the business” of selling firearms can legally sell guns without holding a Federal Firearms License (FFL). This exemption applies to private sellers — people selling from their personal collection, not as a commercial enterprise. The critical distinction is intent: occasional personal sales are permitted; repeatedly buying and selling for profit without an FFL is not.
The Prohibited Persons Rule
The one hard federal line: you cannot knowingly sell a firearm to a prohibited person. Under 18 U.S.C. § 922, prohibited persons include convicted felons, domestic violence misdemeanants, those under certain restraining orders, undocumented immigrants, and others. Selling to any of these individuals is a federal felony, regardless of whether a background check was conducted. This is why careful private sellers always ask to see a valid government-issued ID and use a signed bill of sale.
How State Laws Change the Picture
Federal law sets the floor. States can — and many do — add requirements. As of 2026, more than 20 states have enacted universal background check laws that require all firearm transfers, including private sales, to go through a licensed FFL dealer. States with these requirements include California, New York, Colorado, Washington, Oregon, New Jersey, Massachusetts, Connecticut, and Illinois.
States With No Additional Requirements
In states that have not passed universal background check laws — including Texas, Florida, and Arizona — private sales can occur directly between two individuals without involving an FFL or background check. The seller’s only federal obligation is not knowingly selling to a prohibited person.
What Makes a Private Sale Illegal
- Straw purchases: Buying a gun on behalf of someone prohibited from owning one
- Knowingly selling to a prohibited person
- Dealing without an FFL while engaged in the commercial business of selling firearms
- Shipping directly to an out-of-state individual rather than through an FFL
- Transferring NFA items without the proper tax stamp and registration process
How to Protect Yourself as a Private Seller
Even where private sales require no background check, a few steps reduce your legal exposure significantly. Use a written bill of sale recording both parties’ names, addresses, ID numbers, and the firearm’s serial number. Ask to see the buyer’s government-issued photo ID. If they have a concealed carry permit, request it as a secondary indicator of eligibility. Consider voluntarily going through an FFL even when not legally required — the typical $25–$50 transfer fee is a small price for meaningful peace of mind. For the full federal regulatory framework, the ATF’s Firearms Regulations Reference Guide is the authoritative source.

- More than 20 states require all transfers — including private sales — to go through an FFL
- Knowingly selling to a prohibited person is a federal crime regardless of state law
- A signed bill of sale and ID check are the minimum protections every private seller should use
Frequently Asked Questions About Selling a Gun Privately
Do I need a license to sell my personal guns?
No — federal law does not require a license for individuals who occasionally sell firearms from their personal collection. An FFL is required only for those engaged in the business of dealing firearms commercially for profit on a recurring basis.
Can I sell a gun to a friend without paperwork?
In states without universal background check laws, yes. But a written bill of sale is strongly recommended regardless — it creates a paper trail showing the gun legally changed hands on a specific date, which protects you if the firearm is ever involved in a crime after the transfer.
What if the buyer lies about being prohibited?
If a buyer lies to you and you had no reasonable cause for suspicion, federal law generally protects the seller. If you ignored obvious red flags, however, liability becomes more complicated. Always ask for ID, document the sale, and trust your instincts.
Is the gun show loophole real?
The term refers to private sellers at gun shows being subject to the same rules as private sellers anywhere — no federally mandated background check in states without universal check laws. Licensed dealers at gun shows must still conduct NICS checks regardless of venue.
How do I verify my state’s requirements?
Your state attorney general’s website, the Giffords Law Center’s state law database, or the ATF’s published state laws page are the most reliable current sources. Laws change frequently, so always verify before completing any transfer.
