Idaho vehicle bill of sale

Fill in the free Idaho bill of sale on this page and print it.

ITD says a bill of sale is not needed if the seller enters the selling price and date in the spaces on the title and signs it off. A bill of sale is used when the title has no price, as a release of interest if the seller did not sign off the title, as a 72-hour permit for the buyer, and, with extra steps, when a properly released title cannot be obtained. ITD's bill of sale form has no notary section, and we found no notary requirement.

Use the official form if you prefer it: Bill of Sale (ITD 3738).

Idaho doesn't publish a required list. A complete bill of sale usually has:

• The seller's and buyer's names and addresses
• Year, make, model and VIN
• Odometer reading
• Sale date and price
• An "as is" statement if there's no warranty
• Both signatures and the date

1. Make sure the title is in your name. Reselling a vehicle you have not titled is illegal unless you are a licensed dealer.
2. Sign off the title and enter the date of sale and the true selling price in the spaces on the title.
3. Record the odometer reading if the vehicle needs disclosure (newer than model year 2010 and under 16,000 lbs).
4. Give the buyer the properly signed title, plus a bill of sale (ITD 3738) if the title has no space for the price.
5. Remove your license plates. You keep them.
6. File a release of liability within 5 days of delivery, online or with the tear-off portion at the bottom of the title.

ITD says the seller signs off the title and enters the selling price and date in the spaces designated on the title, along with the odometer reading when required. The release of liability is the tear-off portion at the bottom of the title. ITD's current pages do not say which side of the title holds these fields. The title signature does not need a notary in Idaho.

Required. File Release of liability tear-off portion at the bottom of the Idaho title within 5 days of the sale. You can file it online. It protects you if the buyer gets tickets or tolls, or abandons the car, before retitling it.

Idaho Code 49-431 says the license plates and registration card stay with the seller. Take the plates off before the buyer drives away. You can transfer them to another vehicle you own and get credit for the time left on the registration, paying a $5 transfer fee plus any difference in registration fees. Black and white restricted use plates on off-highway vehicles stay with the vehicle.

Inspection. None tied to a sale between Idaho owners. A VIN inspection by a law officer, DMV employee, military police officer or licensed Idaho dealer is needed when the vehicle comes from another state or has never been titled in Idaho, and the buyer handles it when titling. Idaho's vehicle emissions testing requirement was repealed effective July 1, 2023.

Odometer disclosure. Required for vehicles newer than model year 2010 that weigh under 16,000 lbs. The seller records the mileage on the title when signing it off. ITD's bill of sale (ITD 3738) also has odometer fields with boxes for actual miles, not actual, and exceeds mechanical limits.

Sales tax. The buyer pays Idaho's 6% sales or use tax when titling at the county assessor's motor vehicle office, and a title is issued only after the tax is paid (Idaho Code 63-3619 and 63-3623(l)). ITD says a bill of sale price may be used for the tax if it reflects fair market value, generally the NADA clean retail value. Entering a false selling price on a title or bill of sale is a felony. A qualifying gift can be exempt using form ST-133.

The buyer has 30 days to apply for a new title. The title fee is $14.

Forms used in the transfer:
