Idaho is a bastion of gun ownership, but even in the Gem State, 'straw purchases' are a serious federal concern. Using an Idaho Firearm Bill of Sale is the gold standard for responsible private sales in 2026. This document captures the firearm’s frame-stamped serial number and the buyer’s residency status, ensuring the transaction stays within the bounds of Idaho’s liberal yet clear property laws. It’s not just a receipt; it’s your personal insurance policy against future liability or ownership disputes.
How to fill out a Idaho Gun Bill of Sale
Idaho Firearm Transfer FAQ
Is a Bill of Sale required for private sales in Idaho?
Idaho does not legally require a bill of sale, but it is the standard practice for responsible owners. It serves as your only proof that the firearm was legally sold if it is ever lost, stolen, or used in a crime.
What are the rules for 'Constitutional Carry' in Idaho?
Idaho allows any law-abiding resident 18+ to carry a firearm concealed without a permit. However, the seller must still ensure the buyer is an Idaho resident and not a prohibited person.
Can I sell to a buyer from another state in Idaho?
No. Federal law strictly prohibits private, person-to-person sales between residents of different states. If the buyer is not an Idaho resident, you must use an FFL.
What is the minimum age for a private sale in Idaho?
In Idaho, a resident can purchase a firearm (including a handgun) in a private sale at age 18. Dealers are restricted to 21 for handguns, but private individuals are not.
Is there a gun registry in Idaho?
No. Idaho law explicitly forbids the creation of any list or registry of privately owned firearms. Your Bill of Sale remains a private record between you and the buyer.
Who is a 'prohibited person' in Idaho?
Convicted felons, people under a domestic violence restraining order, or those adjudicated as 'mentally ill' or 'insane' by a court.
Is there a waiting period in Idaho?
No. Idaho has no waiting period. Once the Bill of Sale is signed and payment is made, the transaction is complete.
Should I keep a copy of the buyer’s ID?
Yes. Recording the Idaho Driver’s License number on the Bill of Sale proves you verified the buyer's residency and age, which is your primary defense against federal 'straw purchase' allegations.
