Fill Out an Idaho Bill of Sale Online in 2026

An Idaho bill of sale is a written legal document that records the transfer of ownership of personal property from a seller to a buyer. It provides both parties with evidence of the transaction, including the terms of the sale: the identities of the buyer and seller, a description of the item, the purchase price, and the date.

Idaho Transportation Department (ITD) provides Form ITD 3738 as a standard motor vehicle bill of sale. This form is used when transferring a vehicle title in Idaho and helps establish the taxable purchase price for sales tax calculation. Bills of sale for other personal property can be drafted using any written format that includes the essential transaction details.

An Idaho bill of sale is used to formally document the transfer of personal property and protect both parties in a private sale. Specifically, it is used to:

• Document the transfer of personal property (vehicle, boat, firearm, equipment, or other items) from seller to buyer
• Establish the agreed purchase price on record — Idaho Transportation Department uses this to calculate applicable sales tax, use tax, or registration fees when the buyer applies for a new title
• Protect the seller from future liability related to the property after the sale date
• Give the buyer proof of ownership pending receipt of a new title
• Serve as evidence in any dispute about the terms, price, or condition of the item at the time of sale
• Support insurance documentation — the buyer can present the bill of sale to their insurer as proof of acquisition and value

An complete Idaho bill of sale should include the following information:

• Full legal name and current address of the seller
• Full legal name and current address of the buyer
• Detailed description of the item being sold — for vehicles: year, make, model, color, body type, and VIN; for other property: a clear description with any serial number
• Agreed purchase price
• Date of the transaction
• Current odometer reading at the time of sale (required by federal law for all motor vehicle transfers)
• Signatures of both the buyer and the seller

Idaho law does not require a bill of sale for all private property transfers. For motor vehicle title transfers, the Idaho Transportation Department accepts Form ITD 3738 as supporting documentation to establish the purchase price for sales tax and title transfer purposes.

For Idaho boat and vessel transfers, the Idaho Department of Parks and Recreation may request a bill of sale. In all cases, a bill of sale is advisable to protect both parties.

No. Idaho does not require a bill of sale to be notarized. An Idaho bill of sale is legally valid and enforceable without a notary's signature for personal property transactions, including motor vehicles.

The Idaho Transportation Department does not require notarization for vehicle title transfers. Notarization is optional.

An Idaho bill of sale has no expiration date. Once both parties sign it, it becomes a permanent legal record of the transaction. Neither party needs to renew or re-execute the document—it remains valid indefinitely as long as it accurately reflects the completed sale.

Both the buyer and the seller should keep their signed copies for their personal records. For vehicle transactions, retain the bill of sale until the Idaho Transportation Department has processed the title transfer and issued a new title in the buyer's name. The document may also be needed as proof of purchase for insurance, tax verification, or future ownership disputes.
