Boat tabs in Washington State run from about $30 for a small vessel to several hundred dollars or more for a larger one. The total combines three things: a length-based registration fee set by statute, a 0.5 percent watercraft excise tax on the boat’s fair market value, and a one-dollar derelict vessel removal surcharge.1Washington State Legislature. Washington Code 88.02.640 – Fees by Type, Disposition, Distribution For most owners, the excise tax is the biggest piece of the bill.
The Excise Tax Is Usually the Largest Piece
Washington charges an annual watercraft excise tax equal to 0.5 percent of a noncommercial boat’s fair market value, with a five-dollar minimum.2Washington Department of Revenue. Watercraft Excise Tax Fair market value is calculated by depreciating the most recent purchase price on a schedule developed by the Department of Revenue. If the boat wasn’t bought through a normal sale, or the price doesn’t reflect true value, DOR may appraise it directly.
The math is straightforward once you know the value. A boat with a depreciated fair market value of $20,000 owes $100 in excise tax. A $50,000 vessel owes $250. A $150,000 vessel owes $750. Even a heavily depreciated old boat pays the five-dollar floor. This tax is collected together with your registration fee, so it all shows up as a single payment when you get your tabs.
The Registration Fee and Surcharges
The base registration fee is set by vessel length under RCW 88.02.640, with longer boats paying more.1Washington State Legislature. Washington Code 88.02.640 – Fees by Type, Disposition, Distribution Because the fee schedule has numerous length brackets and your total also depends on the excise tax, the most reliable way to get an exact number for your boat is the Department of Licensing’s online calculator, which factors everything in at once.3Washington State Department of Licensing.

Every registration also includes a one-dollar derelict vessel removal surcharge, which funds cleanup of abandoned boats in Washington waters.1Washington State Legislature. Washington Code 88.02.640 – Fees by Type, Disposition, Distribution If you’re titling a boat in Washington for the first time, a five-dollar title application fee applies as a one-time charge.
A Quick Example
A 20-foot powerboat bought two years ago for $25,000 and now valued at roughly $20,000 would owe its length-based registration fee, plus $100 in excise tax, plus $1 for the derelict vessel surcharge. On boats worth more than a few thousand dollars, the excise tax drives the bill more than the registration fee itself does.
Do You Actually Need Tabs?
Any vessel propelled by a motor or sail that operates on Washington waters must be registered and display its assigned number and decals, and that includes boats with electric trolling motors.4Washington State Department of Licensing. Register a Boat A few categories are exempt:
- Human-powered vessels such as canoes and kayaks, and any boat without a motor or sail.5Washington State Parks. Boat Registration – Section: Exemptions
- Vessels under 16 feet with a motor of 10 horsepower or less, used only on non-federal waters.5Washington State Parks. Boat Registration – Section: Exemptions
- Boats documented with the U.S. Coast Guard, though they may still owe the watercraft excise tax.
- Vessels legally registered in another state, for their first 60 days on Washington waters.
Visiting boaters with an out-of-state registration and a vessel 19 feet or longer also need a $20 aquatic invasive species prevention permit, valid for one year.6Washington State Legislature.

When to Renew and How to Pay
All Washington vessel registrations expire June 30, regardless of when you first registered.7Thurston County. Boat Tab Renewal FAQ You can start renewing as early as January 1 for the year beginning July 1. Licensing offices get busy in June, and operating with expired tabs can bring penalties, so give yourself some cushion.
You have three options:
- Online through the DOL’s License Express portal, if your decals expire within six months. New tabs are mailed to you.8Washington State Department of Licensing. Renew Your Boat Decal
- In person at any vehicle and boat licensing office. Bring a check or money order payable to the Department of Licensing, since many offices don’t accept cards.4Washington State Department of Licensing. Register a Boat
- By mail, with completed forms and payment sent to the DOL.
For a first-time registration, expect to bring proof of ownership (a bill of sale, manufacturer’s statement of origin, or a current out-of-state title), a completed Vessel Title Application, your Hull Identification Number, proof you paid Washington sales or use tax on the boat, and a valid driver’s license or state ID. Boats over 35 feet long and more than 40 years old must also show proof of marine insurance covering general, legal, and pollution liability when the title is transferred or the vessel is first registered.
The Trailer Is a Separate Bill
Boat trailers carry their own license plates and registration in Washington, which is not covered by your vessel tabs. Trailer registration fees depend on the trailer’s weight and type and go through the standard vehicle registration process at the DOL. If you’re buying a boat-and-trailer package for the first time, budget for this as a separate annual cost on top of the numbers above.
