Idaho Vehicle Bill of Sale (2026)
An Idaho vehicle bill of sale is a critical legal document that serves as an official receipt for the transaction between a buyer and a seller. It outlines the specific details of the vehicle transfer, including the purchase price, vehicle identification number (VIN), and the contact information of both parties. This document protects the seller from future liability and allows the buyer to legally prove ownership of the newly purchased vehicle.
In Idaho, a bill of sale is legally required by the Idaho Transportation Department (ITD) to verify the vehicle's purchase price for sales tax calculation. Fortunately, the state of Idaho does not require a vehicle bill of sale or the title signatures to be notarized. However, sellers must complete a Release of Liability within 5 days of the sale, and buyers have exactly 30 days to title and register the vehicle at their local county assessor's motor vehicle office.

Step-by-Step Guide to Selling a Vehicle in Idaho
Step 1: Negotiate the final purchase price and confirm the payment method for the vehicle. Acceptable secure methods for private sales typically include a cashier's check, wire transfer, or cash.
Step 2: Complete the Idaho Vehicle Bill of Sale (Form ITD 3738) and fill out the odometer disclosure reading. Both the buyer and seller must print and sign their names, verifying the exact purchase price, date, and vehicle details.
Step 3: Idaho does not require you to notarize the bill of sale or the vehicle title. Simply ensure all signatures are clear, written in ink, and perfectly match the names printed on the official title document.
Step 4: The seller must sign the vehicle title over to the buyer. Under Idaho law, license plates belong to the seller and must be removed from the vehicle before the buyer takes possession. The seller must also file a Release of Liability (Form ITD 3858) with the DMV within 5 days.
Step 5: The buyer must take the signed title, bill of sale, and proof of Idaho auto insurance to their local county assessor's office within 30 days to register the vehicle. Note that residents of Ada and Canyon counties may also need to provide a passing emissions testing certificate.
Frequently Asked Questions: Idaho Vehicle Bill of Sale
Do I need a bill of sale to sell a vehicle in Idaho?
Yes. The Idaho Transportation Department (ITD) requires a bill of sale to verify the final purchase price for sales tax purposes. The official state document is Form ITD 3738, though a generic bill of sale that contains all required information is generally accepted.
Does an Idaho vehicle bill of sale need to be notarized?
No, Idaho law does not require a vehicle bill of sale or the certificate of title to be notarized for a standard private party sale.
Can I write my own bill of sale in Idaho?
Yes, you can draft your own bill of sale or use a generic template as long as it includes the vehicle year, make, model, VIN, purchase price, date of sale, and the signatures of both the buyer and seller. However, using the state's official Form ITD 3738 is highly recommended by the DMV to prevent any processing delays.
Are private vehicle sales in Idaho considered 'as-is'?
Yes, private vehicle sales in Idaho are strictly considered 'as-is'. Idaho does not have a Lemon Law that applies to used vehicles sold by private parties. Buyers assume all risk and are strongly encouraged to have the vehicle inspected by a trusted mechanic prior to purchase.
How is sales tax calculated on a private vehicle sale in Idaho?
Idaho charges a 6% state sales tax on private vehicle purchases. This tax is calculated based on the final purchase price listed on your signed bill of sale, minus the value of any vehicle traded in during the transaction.
What documents does the buyer need to bring to the Idaho DMV?
To transfer ownership, the buyer must bring the original signed title, a completed Bill of Sale (Form ITD 3738) to prove the purchase price, an Odometer Disclosure Statement (typically located on the title itself), valid personal identification (like an Idaho driver's license), proof of current auto insurance, and payment for title fees, registration fees, and sales tax. A VIN inspection (Form ITD 3403) is also strictly required if the vehicle currently has an out-of-state title.
