Title & Registration in Wisconsin

Wisconsin requires a certificate of title for boats and personal watercraft. When you purchase a vessel, the seller must sign the title over to you. You then have a limited window to apply for a new title in your name.

Apply at a county clerk's office or DMV customer service center within 30 days. Bring the out-of-state title and proof of Wisconsin use tax payment.

Lien Search in Wisconsin

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

Wisconsin 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 Wisconsin

Sales Tax on Boats & Powersports in Wisconsin

Wisconsin charges 5.00% 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 Wisconsin agency for the full rate.

USCG Documentation in Wisconsin

Lake Michigan and Lake Superior border Wisconsin; USCG documentation is common for sailboats and large powerboats.

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, Wisconsin may still require state registration for operation on in-state waters.
