Free Idaho Vehicle Bill of Sale Form (ITD 3738 Compliant PDF)

Q: Is a bill of sale required to transfer a car title in Idaho?

Yes. When purchasing a vehicle from a private party in Idaho, the County Assessor Motor Vehicle office mandates a completed Bill of Sale (Form ITD 3738 compliant) whenever the sales price or full odometer disclosure is not directly documented on the Certificate of Title.

Q: What is Idaho Form ITD 3738?

Form ITD 3738 is the official Idaho Transportation Department Bill of Sale format. It establishes the purchase price for Idaho 6.0% state sales/use tax calculation and includes the statutory Federal Truth-in-Mileage odometer disclosure statement.

Q: How long does a seller have to report a vehicle sold in Idaho?

Under Idaho Code § 49-509, the seller MUST file Form ITD 3126 ('Notice of Release of Liability') with the Idaho Transportation Department within strictly 5 calendar days of the sale to cancel legal liability for moving violations, toll charges, or abandoned towing fees.

Q: What is the penalty for not titling a vehicle within 30 days in Idaho?

Under Idaho Code § 49-507, the buyer must apply for title and registration at the local County Assessor’s Motor Vehicle office within 30 calendar days of the sale. Failing to title within 30 days incurs a mandatory $20 late penalty fee.

Q: Does an Idaho vehicle bill of sale need to be notarized?

While standard private sales with clear title do not statutorily require notarization if both parties sign the title transfer, having Form SBF-ID-3738 notarized is strongly recommended by County Assessors to prevent disputed sales prices, identity fraud, and rejected title applications.
