Forming an LLC for your boat in Washington

The 0.5% annual excise tax, the new 0.5% vessel tax at purchase, use tax, and the 60-day nonresident window — everything a boat LLC on Puget Sound actually pays, and doesn't avoid.

Washington is one of the friendlier states to own a boat in on paper — no state income tax — but the water isn’t free. The state charges an annual 0.5% watercraft excise tax on a boat’s value in place of property tax, layers use tax plus a new 0.5% vessel tax on when you buy, and it watches the marinas on Puget Sound closely. An LLC can be the right way to hold a boat kept in Seattle, Tacoma, or the San Juans, but it changes liability and ownership — not the tax bill.

The excise tax is billed by the Department of Licensing at annual renewal; use tax and the new vessel tax are administered by the Department of Revenue. A nonresident gets 60 days on Washington waters without registering, extendable once via a nonresident vessel permit (six-month cap). Registration itself runs through WA DOL (a WN number) or USCG documentation for vessels of 5+ net tons.

Why Washington boat owners form LLCs

The core reasons match our national boat LLC guide, and none of them are about tax:

  • Liability separation. A guest hurt on the swim step, a crewed weekend gone wrong, a fuel-dock incident — when an LLC owns the boat, a boat-related claim is aimed first at the LLC and its assets rather than everything you own. It never shields you from your own negligence at the helm, and marine insurance stays your first line of defense.
  • Co-ownership. Partnership boats are common in expensive Seattle and Bellingham slips. An LLC gives shared owners real percentages, an operating agreement, and a buyout mechanism that doesn’t require re-titling the boat every time someone joins or leaves.
  • Privacy. The LLC’s name — not yours — appears on registration, documentation, and marina paperwork.
  • Transfers. Selling membership interests can move the boat without re-documenting the hull — with the honest caveat that Washington tax agencies look at substance, and a transfer built to dodge tax invites scrutiny.

What an LLC does not do in Washington: make the use tax, the new vessel tax, or the annual watercraft excise tax disappear. Here’s each, precisely.

The 0.5% watercraft excise tax

This is Washington’s signature boat tax, and the one most out-of-state owners underestimate. Under RCW 82.49, registered recreational vessels owe an annual watercraft excise tax of 0.5% of the boat’s fair market value (with a $5 minimum) — charged in lieu of the personal property tax that would otherwise apply. It’s collected through the Department of Licensing, typically bundled into your annual registration renewal and due by June 30.

The math is simple and recurring. A boat valued at $200,000 owes about $1,000 a year; a $500,000 vessel, about $2,500. Fair market value is the latest purchase price run through a Department of Revenue depreciation schedule tied to the boat’s age, so the bill drifts down as the boat gets older — but it never falls below the $5 minimum while the boat is registered in Washington.

Buying a boat: use tax and the new 0.5% vessel tax

Buy a boat from a Washington dealer and retail sales tax is collected at the sale. Buy from a private party, or out of state, and Washington use tax applies instead when the boat is brought in for use here. The rate is the combined state-and-local rate for where the boat is kept — the state portion is 6.5%, and local add-ons push the total to roughly 8% to 10.6% depending on the marina’s jurisdiction. A boat kept in Seattle is taxed at Seattle-area rates; one in Anacortes at Skagit County rates.

New for 2026: on top of sales or use tax, Washington now imposes a recreational vessel tax of an additional 0.5% on the full purchase price of a recreational vessel — with no threshold or trade-in deduction for vessels the tax actually covers — effective July 1, 2026. Under RCW 82.49.020, it exempts vessels under 16 feet in overall length, vessels used exclusively for commercial fishing, and vessels owned by certain nonprofit organizations. It’s due at the time of purchase or at first use in Washington: a Washington dealer collects it at the sale, and a buyer who bought elsewhere pays it when registering with the Department of Licensing.

The nonresident vessel permit

Washington has a real accommodation for visiting boats — but it’s narrower than most owners assume. A nonresident can use a boat on Washington waters for up to 60 days without registering here, no permit required. To stay beyond 60 days, the owner must buy a nonresident vessel permit from the Department of Licensing before the 61st day; it can be renewed once for another period, and total exempt time can’t exceed six months in any continuous 12-month period. After that, the boat must be registered in Washington or removed from state waters.

No income tax — but watch the B&O line

Washington’s big structural advantage is that it has no state personal or corporate income tax. A single-member LLC that simply holds a boat for personal use generally has no Washington income-tax filing on that basis, and no franchise-tax equivalent of the kind California charges. For a pure holding structure, that’s a clean picture.

The exception to keep in view is Washington’s business and occupation (B&O) tax, which is levied on gross business revenue rather than profit. A holding LLC with no revenue typically has no B&O activity. But the moment the LLC charters the boat — even occasionally — it’s operating a business, and charter income can be B&O-taxable, on top of the different insurance, Coast Guard, and licensing exposure that commercial operation brings. If chartering is any part of the plan, design it with a Washington tax professional rather than discovering the B&O line after the fact.

DOL registration vs USCG documentation

Washington runs the same two-track ownership system as the rest of the country, and an LLC can be the owner on either track:

  • WA DOL registration. Undocumented vessels register with the Department of Licensing, which issues the WN number for the hull and collects the annual watercraft excise tax at renewal. This is also where a private-party purchase gets reconciled against use tax and the new recreational vessel tax.
  • USCG documentation. Vessels of at least five net tons (a volume measure — many boats from roughly the mid-20-foot range up qualify) wholly owned by U.S. citizens can be federally documented with the National Vessel Documentation Center instead of titled by the state. Documented vessels still owe Washington’s watercraft excise tax and register with DOL for a validation decal, but they carry a federal Certificate of Documentation rather than a state title. An LLC can be the documented owner if it meets the Coast Guard’s citizenship requirements — for a recreational endorsement, NVDC guidance requires the LLC’s members to be U.S. citizens.

Either way, the state finds the boat: DOL and marina reporting mean the excise and use-tax bills arrive whether the hull carries a WN number or a federal documentation number.

The Seattle and Puget Sound hook

Most of Washington’s recreational fleet lives in a narrow band of saltwater, and that’s exactly where enforcement is tightest:

  • Seattle / Lake Union / Shilshole. The densest cluster of high-value slips in the state. Marinas here report slip holders, and a boat wintering at Shilshole is not a “visiting” boat under the permit rules.
  • Tacoma / Gig Harbor / South Sound. Lower slip costs, same tax regime — the excise tax follows value, not location.
  • San Juan Islands / Anacortes / Bellingham. Prime cruising ground and a common landing point for boats coming down from British Columbia. This is where the nonresident permit gets used legitimately — and where DOR pays attention to boats that quietly stop leaving.

None of these locations changes the tax math. A boat kept anywhere on Puget Sound is a Washington-taxed boat; the LLC’s value is in liability, co-ownership, and privacy, not geography.

Before transferring a boat you already own into a new LLC, check the tax consequences and get lender consent if the boat is financed — Washington can treat a transfer for consideration as a taxable event, and a title change can re-trigger use-tax questions.

Where FilingDesk fits

FilingDesk doesn’t file directly in Washington — but Washington’s boat taxes attach to the boat, not the LLC’s home state, so most owners don’t need a Washington entity anyway. FilingDesk forms Wyoming, Florida, and Delaware LLCs today — flat $99 plus the state fee ($199, $224, and $209 all-in respectively), with a human specialist reviewing every filing, EIN and operating agreement included, no upsells. For a Washington-kept boat, many owners hold the vessel in a Wyoming LLC for its low cost and privacy.

Describe your business in plain English and we’ll file it — the boat-specific steps (titling, USCG documentation, insurance, and the tax at purchase) stay with you and your marine pros.

Frequently asked questions

How much is the annual watercraft excise tax in Washington?
Washington charges a watercraft excise tax of 0.5% of the vessel's fair market value each year, with a $5 minimum, collected in lieu of personal property tax on registered recreational boats. The Department of Licensing bills it at annual registration renewal, due by June 30. A boat valued at $200,000 owes about $1,000 a year. Value follows a state depreciation schedule, and an LLC-owned boat pays it the same as a personally owned one.
Does Washington charge sales or use tax when I buy a boat?
Yes, and as of July 1, 2026 there are two charges at purchase. A Washington dealer collects retail sales tax; a private-party or out-of-state boat brought in for use here owes use tax instead, at the combined state-and-local rate where the boat is kept — roughly 8% to 10.6%. On top of that, a new 0.5% recreational vessel tax now applies to the full purchase price, due at purchase or first use in Washington. Both are separate from the recurring 0.5% annual excise tax.
What is the nonresident vessel permit?
A nonresident can use a boat on Washington waters for up to 60 days without registering here. To stay beyond 60 days, you buy a nonresident vessel permit from the Department of Licensing before day 61; it can be renewed once, and total exempt time can't exceed six months in any 12-month period. For entity-owned boats the permit only covers vessels 30 to 300 feet, for personal use, with no Washington resident as a principal — so a Washington owner's LLC generally can't use it.
Does a Wyoming or Montana LLC avoid Washington boat tax?
No. Washington's use tax, the new 0.5% recreational vessel tax, and the annual watercraft excise tax attach to a boat used and moored in Washington, not to the owner's state of formation. If the boat lives on Puget Sound, Washington's rules apply regardless of an out-of-state LLC on the title. Out-of-state LLCs remain useful for liability, co-ownership, and privacy — they are not a device to escape Washington's boat taxes.
Does Washington have a state income tax on an LLC that holds a boat?
Washington has no state personal or corporate income tax, so a single-member LLC holding a boat generally has no state income-tax filing on that basis. Washington does levy a business and occupation (B&O) tax on gross business revenue, which can reach an LLC that charters the boat commercially. A pure holding LLC with no revenue typically has no B&O activity, but confirm with a Washington tax professional.
Do I register my boat with Washington or the Coast Guard?
Undocumented vessels register with the Washington Department of Licensing, which issues the WN number and collects the excise tax at renewal. Boats of at least five net tons can instead be federally documented with the USCG; documented vessels still owe Washington's watercraft excise tax and register with DOL for a validation decal, but skip state title. An LLC can be the owner in either system, subject to Coast Guard citizenship rules for documentation.
