Title & Registration in Idaho

Idaho does not issue titles for recreational boats. Instead, vessels are registered with the state. The registration certificate and bill of sale serve as proof of ownership.

Idaho does not title boats. Register the vessel with Idaho Parks and Recreation within 30 days. Bring a bill of sale and current registration.

Lien Search in Idaho

Before completing any private-party purchase, run a lien search to confirm the vessel has no outstanding loans or encumbrances.

For USCG-documented vessels, also search the National Vessel Documentation Center (NVDC).

Bill of Sale Requirements

Idaho requires a bill of sale to transfer title. Your bill of sale should include:

Hull Identification Number (HIN) or VIN
Make, model, and year of the vessel
Full legal names and addresses of buyer and seller
Purchase price and date of sale
Odometer reading (motorhomes/RVs)
Signatures of both parties
Notarization if required by Idaho

Sales Tax on Boats & Powersports in Idaho

Idaho charges 6.00% sales tax on boat and powersports purchases. Sales tax is typically collected when you register the vessel with the state. Some counties add additional local taxes. Check with your local Idaho agency for the full rate.

USCG Documentation in Idaho

USCG documentation is generally not applicable for Idaho inland waters. All motorized vessels must be registered with Idaho Parks & Recreation.

USCG-documented vessels carry a Certificate of Documentation (COD) issued by the National Vessel Documentation Center. This is recognized internationally and is preferred by lenders for boats over 26 ft. Even with USCG documentation, Idaho may still require state registration for operation on in-state waters.
