Washington Boat Bill of Sale Overview
Washington registers boats through the Department of Licensing (DOL) with boating safety oversight by State Parks. The Evergreen State's Puget Sound, San Juan Islands, Columbia River, and Lake Chelan offer world-class boating. All motorized vessels must be registered.
Washington's 6.5% state sales tax applies to boat purchases, and local taxes may increase the total. The tax is calculated from the purchase price stated on the bill of sale, making accurate documentation essential.
Washington does not require notarization of boat bills of sale for most transactions, though having the document notarized is recommended for higher-value vessels. The Washington State Parks / DOL processes title transfers and new registrations.
