About the Gun / Firearm Bill of Sale

A firearm bill of sale documents private gun sales and must include the weapon's serial number, caliber, make, and model. Federal law generally allows private firearm sales between residents of the same state without a dealer transfer, but many states have enacted universal background check laws that require all transfers β€” including private sales β€” to go through a licensed dealer (FFL). Our form includes fields for both compliant and restricted-state transactions.

When to Use This Form

Use a firearm bill of sale for private sales of handguns, rifles, shotguns, and other legal firearms. Always verify your state's private transfer laws before completing the sale β€” many states now require FFL dealer involvement even in private transactions.

Legal Tip

In states with universal background check laws (including California, Colorado, Illinois, New York, Oregon, and Washington), private firearm sales must be processed through a licensed FFL dealer. Do not complete a private transfer without checking your state's current law.

Frequently Asked Questions

Is a gun bill of sale required by law?
Federal law does not require a bill of sale for a private firearm transfer, but most states strongly recommend one. Some states require it as part of the background check process. It is always good practice to document the transfer.
What states require background checks for private gun sales?
As of 2026, states requiring background checks for all private firearm transfers include: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, Nevada, New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Virginia, and Washington. This list changes as laws are updated β€” always verify current state law.
Should I keep a copy of a gun bill of sale?
Yes. Both buyer and seller should keep signed copies indefinitely. If the firearm is later used in a crime, the bill of sale documents when and to whom you transferred the weapon, which can be critical evidence.
