How to Register

You have up to 30 days to title and register your vehicle after the time of purchase in the state of Idaho. Once the 30 days expire, you can no longer legally operate your vehicle on public roadways. To begin the registration process, you must appear in person before your local county assessor at an Idaho Transportation Department office with:

• The bill of sale (if there was no available space to record the purchase price).
• The title is signed by the previous owner, transferring ownership to the individual registering the vehicle.
• With this particular bill of sale, the seller must execute an Idaho Release of Liability Statement (Form ITD—3858). Once completed, the document must be delivered to the Idaho Transportation Department and processed for a fee of $3.50.
• Applicant must provide a completed Application for Certificate of Title (Form ITD 3337).
• A Vehicle Identification Number Inspection Certification – Form ITD 3403 (filled out with the requested information and signed by the applicant(s) and authorized official).
• If the vehicle being processed for registration is less than ten years old and weighs less than 16,000 pounds, the odometer reading must be disclosed.
• An Idaho-issued driver’s license or ID.
• Some form of proof confirming the existence of an auto insurance policy.
• Payment for any mandatory registering fees and/or state taxes.

How to Register a Vessel

To lawfully employ the use of a watercraft upon waters located in the State of Idaho, you must officially register the boat within the jurisdiction. Also, when purchasing a new boat, you must register within the first 15 days to avoid penalty fees. Any vessel that uses a sail or is mechanically propelled by a motor is held by this standard with the following exemptions:

• Non-motorized vessels.
• Emergency lifeboats.
• Sailboards.
• Vessels registered in an alternate state or country are to be utilized for a period of time of less than 60 continuous days in any one-year time period.
• Vessels owned by the federal or state authorities.

The registration application process can be completed at your nearest Idaho DMV facility or a participating boat registration vendor with the following materials:

• A fillable Idaho Boat Registration Application (made available on-site at the time of registration).
• A regulated Idaho Certificate of Title (If the vessel is purchased new or from out-of-state, you must apply for one. If you are purchasing the boat from a private seller, have the previous owner sign over the title to you at the time of purchase).
• A unique identifier is associated with the boat owner, such as a social security number, photo ID, or company employer identification number.
• A photograph of your vessel’s hull identification number may need to be verified to grant registration.
• Certificate of completion of the Official Idaho Boating Safety Course exam available online.
• Funds to compensate the registration fees and applicable taxes.
