A buyer submitting false information on a Form 4473 is a federal crime. What happens to the dealer depends almost entirely on what the dealer knew — or should have known — at the time of the transfer.

The Dealer's Legal Standard

Federal law prohibits FFL dealers from transferring a firearm to a buyer they know or have reasonable cause to believe is prohibited. The key phrase is "reasonable cause to believe." You are not required to be a mind reader or a lie detector. You are required to ask the questions on the form, verify the buyer's identity with acceptable ID, and act on any red flags that are apparent.

The "knowing" standard matters: If a buyer lies about their state of residence, their prohibited status, or the purpose of the purchase, and nothing about the transaction indicated they were lying, the legal exposure falls on the buyer — not the dealer. The crime is the buyer's false statement under 18 U.S.C. § 922(a)(6).

Red Flags You Cannot Ignore

Where dealers get into trouble is ignoring obvious indicators of a problem. A buyer who hesitates on Question 21, asks a companion which boxes to check, or is purchasing a specific firearm they say is for someone else are all red flags that should stop the transaction. Completing the transfer while ignoring these signals creates exposure for the dealer.

Common red flags include: a third party paying for the firearm, the buyer asking for help filling out the form, inconsistencies between the ID and the form, the buyer being unfamiliar with basic details about the firearm they are purchasing, and any direct statement suggesting the purchase is for another person.

What to Do When You Suspect a Problem

You have the right to refuse any transfer for any reason that is not discriminatory. If something about a transaction feels wrong, you are not obligated to complete it. Refusing a transfer that turns out to be legitimate is an inconvenience. Completing a transfer that turns out to be a straw purchase or an attempt to circumvent the background check is a federal compliance problem.

Document your refusal. If you refuse a transfer due to suspected false information, note it in your records with the date, reason, and description of the transaction. This documentation protects you if the situation is later investigated.

After the Transfer: Discovering a False Statement

If you complete a transfer and later learn the buyer provided false information — a gun comes back in a trace, law enforcement contacts you, or you discover an inconsistency — cooperate fully with law enforcement and contact your attorney. Your records of the completed Form 4473 are evidence that you followed the required process.

The Form 4473 is your protection in this scenario. A properly completed form documenting the buyer's answers, your ID verification, and the NICS result demonstrates that you fulfilled your legal obligations at the time of transfer.
