Should you put your boat in an LLC?

A boat is an unusual asset: expensive, publicly registered, capable of hurting people, and often shared between friends or family. That combination is exactly what LLCs were built for — and it’s why marinas from Fort Lauderdale to Marina del Rey are full of boats titled to companies rather than people. But there’s also a persistent myth attached to boat LLCs: that the right out-of-state LLC makes sales tax disappear. It usually doesn’t, and believing it can cost you real money.

This guide covers what a boat LLC actually does, how ownership works with state registration and Coast Guard documentation, and the honest version of the tax question.

Why boat owners use LLCs

Liability separation

Boats generate liability in ways a brokerage account never will: a guest slips on a wet swim platform, a crew member is hurt handling lines, your wake swamps a smaller boat, a fuel-dock mishap turns expensive. If you own the boat personally, a serious claim can reach past the boat to everything else you own.

When an LLC owns the boat, a claim arising from the boat is — in principle — a claim against the LLC and its assets.

Insurance remains the first line of defense; the LLC is the second. You want both.

Privacy

State vessel registrations and USCG documentation records are public. Title the boat to “Blue Heron Holdings LLC” and it’s the company’s name — not yours — that shows up in registry lookups, marina paperwork, and the documentation database. States vary in how much they disclose about LLC owners; Wyoming, notably, doesn’t put member names on the public formation record, which is one reason it’s a popular home for holding companies. (See our Wyoming LLC guide.)

Shared ownership

Two couples splitting a trawler, four friends buying a fishing boat, siblings inheriting the family cruiser — co-ownership without a structure is a handshake deal on a six-figure asset. An LLC gives you membership percentages, an operating agreement that spells out who pays for the bottom job and who gets July 4th weekend, and a clean mechanism for one owner to buy out another without re-titling the boat.

Easier transfer

When the LLC owns the boat, selling or gifting the boat can be done by transferring LLC membership interests instead of re-titling or re-documenting the vessel. For estate planning, membership interests can pass to heirs while the boat’s title and documentation never change hands. A word of honesty: some states look through LLC-interest transfers for tax purposes, and a buyer purchasing your LLC inherits its liabilities too — so real transactions still deserve professional advice.

Registration, titling, and USCG documentation

Boats have two parallel ownership systems in the U.S., and your LLC can be the owner in either one:

• State registration and titling. Every state registers boats used on its waters, and most title them, through its motor-vehicle or natural-resources agency. An LLC can be the registered/titled owner — you’ll list the company name and typically its EIN on the application.
• USCG documentation. Larger boats can instead (or additionally) be federally documented with the Coast Guard’s National Vessel Documentation Center. Eligibility starts at five net tons — a volume measure, not weight; many boats from roughly the mid-20-foot range up qualify — and the vessel must be wholly owned by U.S. citizens. Documentation is voluntary for recreational boats and mandatory for most commercial vessels of five net tons or more in coastwise trade or fisheries.

Lenders often prefer documented vessels because they can record a preferred ship’s mortgage against the documentation — worth knowing if your LLC will finance the boat.

The sales-tax truth: an LLC is not a tax dodge

Here is the section that separates honest advice from marina folklore.

The pitch you’ll hear: form an LLC in Montana (no general sales tax) or Delaware (no sales tax on boats), have the LLC buy the boat, and skip your home state’s sales tax. The problem is that sales tax has a twin — use tax — and use tax follows the boat, not the LLC. Every sales-tax state imposes use tax on boats principally used, moored, or stored in that state, regardless of where they were purchased or who owns them.

Concretely, from the states’ own rules:

• Florida imposes its 6% use tax (plus county surtax, capped overall at $18,000 per boat) on boats brought into the state within six months of purchase — and boats bought anywhere in the world that take up residence at a Miami, Fort Lauderdale, or Tampa dock get registered, and registration is where the tax gets collected. Florida’s nonresident-purchase exemption explicitly does not apply to entities controlled by Florida residents. Full detail in the Florida DOR’s boat tax brochure (GT-800005) and our Florida boat LLC guide.
• California applies use tax at the rate in effect where the boat is principally moored — a boat kept in San Diego, Marina del Rey, or a San Francisco Bay marina owes tax at that local rate — and presumes a boat brought into the state within 12 months of purchase was bought for California use. The CDTFA identifies vessels through registration and documentation records and contacts owners. Details in our California boat LLC guide.
• Maryland charges a 5% vessel excise tax on boats used principally in Maryland, per the Maryland DNR — the rule that matters for the Annapolis and Chesapeake crowd, and for Washington, DC-area boaters on the Potomac, where a slip on the Maryland side puts you squarely in the DNR’s system. The tax is capped ($16,100 as of July 1, 2026, adjusted annually) with registration due within 30 days.

Enforcement isn’t hypothetical. States cross-reference marina slips, registration databases, USCG documentation records, and insurance addresses. An LLC named on the title doesn’t hide the boat; the boat is the most visible asset you own.

One more tax trap worth flagging: re-titling a boat you already own into your new LLC can itself be treated as a taxable transfer in some states — especially if the boat carries a loan. Check your state’s transfer rules (or ask a professional) before you move an existing boat in.

Insurance: call before you transfer

Insurance is the piece people forget, and it’s the one that can actually sink you. Before the LLC takes title:

• The named insured must match the owner. If the LLC owns the boat, the LLC needs to be the named insured (with you added as an additional insured or operator). A mismatch invites a denied claim.
• Be straight about use. Recreational policies exclude commercial use. If the LLC will charter the boat — even occasionally — you need a charter or commercial marine policy, and bareboat-charter arrangements have their own insurance and Coast Guard implications.
• Financed boats need lender consent before any title change.

Most marine insurers handle LLC-owned recreational boats routinely; it’s a phone call, not a crisis. Skipping the phone call is the crisis.

What it costs

The LLC is a rounding error next to the boat:

Add a registered agent service if you don’t have an address in the state (typically $50–$150/year), your state’s title-transfer or documentation-exchange fees, and any insurance premium change.

How to do it

1. 1

   Form the LLC

   Pick the right state — usually the state where the boat lives, or Wyoming/Delaware for a pure holding structure — and file the formation documents.

2. 2

   Get the LLC's EIN and open a bank account

   The EIN is free from the IRS. Open a business bank account in the LLC’s name before anything else moves through it.

3. 3

   Sign an operating agreement

   Especially with co-owners — this is where usage schedules, expense splits, and buyouts live.

4. 4

   Transfer or take title in the LLC's name

   State title/registration, USCG documentation exchange, or both. Buying new? Have the LLC purchase from day one and you skip the transfer step (and its tax questions) entirely.

5. 5

   Update insurance and lender paperwork

   Do this before, not after, the title changes hands.

Flat $99 plus the state fee: Wyoming $199, Delaware $209, Florida $224 all-in, no upsells. The boat-specific steps — titling, documentation, insurance — stay with you and your marine professionals, but the company that holds the boat can be done today. Start here.
