Connecticut boating runs the full length of Long Island Sound — Greenwich, Stamford, Norwalk, Milford, the Connecticut River up to Essex and beyond, Mystic and Stonington at the eastern end. And unlike most of its neighbors, Connecticut has spent four decades deliberately making itself cheap for boats: it dropped its vessel sales tax to a flat 2.99% in 2018 to stop losing sales to Rhode Island, it hasn’t charged property tax on a boat since 1981, and it doesn’t tax winter storage or repair work at all. That inverts the usual boat-LLC story. In most states, the guide has to talk you out of a tax scheme; in Connecticut, there’s barely any tax to scheme against. What’s left are the reasons an LLC actually earns its keep — liability, co-ownership, privacy — and a set of registration mechanics worth getting right the first time.

Why Connecticut boat owners form LLCs
The reasons track our national boat LLC guide, with Connecticut color:
- Liability separation. A boat that hosts guests off Norwalk or rafts up in Essex is a liability generator. When an LLC owns it, a boat-related claim aims first at the LLC and its assets rather than your home and savings. It never shields you from your own negligence at the helm — insurance stays your first line of defense.
- Co-ownership. Partnership boats are everywhere on the Sound, where slips are scarce and the season is short. An LLC gives shared owners real percentages, an operating agreement, and a buyout mechanism that doesn’t require re-registering the boat every time someone joins or leaves.
- Privacy. The LLC’s name — not yours — goes on the registration, the title, and the marina contract. How much anonymity that buys depends on the formation state: a Wyoming LLC discloses less about its members than a Connecticut filing.
- Estate and succession planning. Membership interests can transfer without re-titling the vessel — useful for family boats and larger yachts. Connecticut looks at substance, so transfers engineered purely around tax invite scrutiny; get advice first.
- Charter operations. If the LLC will rent or charter the boat — even casually — you’ve crossed into commercial territory with different insurance, Coast Guard, and tax consequences. That’s a different structure; see our boat charter LLC guide.
The 2.99% vessel tax: how it works
Connecticut’s general sales tax rate is 6.35%. But since July 1, 2018, vessels, motors for vessels, and trailers used for transporting a vessel are taxed at a reduced flat rate of 2.99% — the rate cut the legislature passed after watching boat sales drain to no-tax Rhode Island next door. The mechanics, per the DRS’s IP 2021(10), Q & A on Purchases of Vessels:
- Which boats qualify: as a general rule, a vessel of a type that must be registered with the DMV. That covers all motorboats (any watercraft fitted with propulsion machinery, whatever its size), non-motorized vessels 19½ feet or longer that aren’t propelled solely by paddles or oars (sailboats, principally), and personal watercraft. Canoes, kayaks, and non-motorized boats under 19½ feet don’t qualify — those purchases pay the standard 6.35%.
- Trade-ins reduce the taxable price. Trade a vessel in to a retailer toward another vessel and tax is computed on the difference (Conn. Gen. Stat. §12-430(4)).
- No cap. Unlike New York, New Jersey, Florida, or Maryland, Connecticut has no ceiling — a $2 million boat pays 2.99% on all $2 million.
- Credit for tax paid elsewhere. Sales or use tax lawfully paid to another state offsets Connecticut use tax on the same boat, provided you paid it before Connecticut issued a use-tax assessment.
- Dyed diesel at the fuel dock sold by a licensed marine fuel dock exclusively for marine purposes is also taxed at 2.99% (since October 1, 2019).
Buy from a Connecticut dealer and the dealer collects the 2.99%. Buy from a private party or out of state and the tax doesn’t vanish — the DMV collects it when you register the vessel, per its sales-tax-at-registration rules. Gifts are the main exception: a vessel received as a genuine gift, with a signed Gift Declaration (form AU-463) and no consideration flowing back, owes no sales or use tax.
How Connecticut stacks up against its neighbors
| State | Boat sales/use tax | The mechanics |
|---|---|---|
| Connecticut | 2.99% flat | No cap; applies to vessels, motors, and trailers (CT DRS IP 2021(10)) |
| Rhode Island | None | Boats fully exempt from sales and use tax since 1993 (R.I. Gen. Laws §44-18-30) |
| New York | 4% + local (8%–8.875% in most boating counties) | Only the first $230,000 of the price is taxable (TSB-M-15(2)S) |
| New Jersey | 3.3125% — half the general rate | Capped at $20,000 per vessel (NJ Division of Taxation) |
| Massachusetts | 6.25% | No cap; due on Form ST-6 by the 20th of the month after purchase or entry (Mass.gov) |
What that means in dollars, at New York City’s 8.875% combined rate for the New York column:
| Boat price | Connecticut (2.99%) | Rhode Island | New York (NYC) | New Jersey | Massachusetts |
|---|---|---|---|---|---|
| $150,000 | $4,485 | $0 | $13,312.50 | $4,968.75 | $9,375 |
| $400,000 | $11,960 | $0 | $20,412.50 (capped) | $13,250 | $25,000 |
| $1,000,000 | $29,900 | $0 | $20,412.50 (capped) | $20,000 (capped) | $62,500 |
What Connecticut doesn’t tax at all
The 2.99% headline is only half of Connecticut’s pitch to boat owners. The quieter half, all from IP 2021(10) and the legislative record:
- No property tax on boats — since 1981. Public Act 81-423 exempted boats (and aircraft) from local property tax and replaced it with the annual state registration fee. The legislature’s own debate records tell the story: shoreline towns couldn’t collect a tax that boat owners legally avoided by moving moorings, and registrations were leaking to other states. Compare that with a state like California, where county assessors value boats as of January 1 each year and tax them at the 1% basic rate plus local voter-approved add-ons, or the personal-property regimes in much of New England — over a decade of ownership, this exemption is worth real money.
- Repair and maintenance services to vessels are exempt from sales and use tax — the yard’s labor bill for mending, refit work, shrink wrapping, washing, painting, and varnishing is untaxed, as long as parts are separately stated (parts are taxable — most at 6.35%, replacement motors at 2.99%). Fabrication labor to customize an existing vessel is exempt on the same separately-stated terms.
- Winter storage and mooring are exempt from sales tax from October 1 through May 31. Storage or mooring of a noncommercial vessel is taxable only outside that window — and a boat that comes into Connecticut during those months solely for storage, maintenance, or repair doesn’t trigger Connecticut use tax by being here. One exception worth knowing: where mooring and storage are billed as dues to a social, athletic, or sporting club — a yacht club, in practice — those charges are subject to Connecticut’s dues tax without regard to the time of year, so the winter window doesn’t rescue them.
- Marine vessel brokerage services are exempt when a broker sells the boat for its owner.
The two 60-day rules
Connecticut has two separate 60-day tests that boat owners routinely conflate. They come from different statutes and do different things:
- Registration (the decal rule). A vessel that’s USCG-documented or numbered by another state must display a Connecticut registration decal once it’s used on Connecticut waters for more than 60 days in a calendar year — Conn. Gen. Stat. §15-142(b). A summering visitor on New York or Rhode Island papers who stays past 60 days owes Connecticut a registration.
- Sales tax (the CERT-143 exemption). A purchaser — resident or nonresident — who will dock the newly bought boat in Connecticut for 60 or fewer days in a calendar year can buy from a Connecticut retailer exempt from sales and use tax, claiming the exemption on form CERT-143. This is how Connecticut dealers sell to buyers whose boats will live elsewhere without losing the deal to an out-of-state broker.
Registering the boat in your LLC’s name
Connecticut registers vessels through the DMV — by appointment at a DMV hub or branch office, or at a participating dealership, rather than online — and an LLC can be the registrant. Registration is where the state’s paperwork, tax collection, and fee-in-lieu-of-property-tax all converge, so here are the mechanics that matter:
- Who must register: every motorboat regardless of size, non-motorized vessels 19½ feet and over (unless propelled solely by oars or paddles), and personal watercraft. Non-motorized boats under 19½ feet, and paddle craft of any length, are exempt.
- Fees run by length, per the DMV’s vessel fee chart: from $7.50 for a fiberglass or metal hull under 12 feet, stepping up to $480 at 64–65 feet and $525 for 65 feet and over. Wood hulls get a discount — 50% of the fee at 15–24 years old, 25% at 25 years or older — and a non-houseboat pontoon boat is a flat $40; canoes with motors and low-power vessels (under 15 feet and under 15 hp) are $7.50.
- Registrations expire April 30 and renew annually. Note for entity owners: organizations can’t renew online — an LLC-owned boat renews by mail or in person.
- Titles: Connecticut titles vessels with a model year of 2017 or newer ($25 title fee, $10 lien fee if financed). Older boats are registered without a Connecticut title.
- USCG-documented vessels can’t receive a Connecticut title, but they still register and display a CT decal when the 60-day use threshold is crossed. An LLC can be the documented owner, subject to the Coast Guard’s citizenship requirements for a recreational endorsement.
- Tax is collected at the counter. If 2.99% wasn’t paid to a Connecticut dealer, the DMV collects it at registration, based on the purchase documentation you bring.
- One Connecticut-specific trap: the DMV blocks vessel registration and renewal when you have outstanding property tax obligations — its renewal page lists unpaid property tax on the vessel, and unpaid taxes generally, as a bar to renewing online, by mail, or in person. Clear any municipal tax compliance holds before the trip to the DMV hub.
One more line item since October 1, 2024: the Aquatic Invasive Species stamp is no longer bundled into vessel registration. Anyone operating a registrable vessel on Connecticut’s inland waters — DEEP puts the dividing line at roughly the first bridge upstream from a river’s mouth, so Long Island Sound itself sits outside it — needs an AIS stamp from DEEP’s licensing system: $7 per person per calendar year, or a $25 vessel decal ($20 plus a $5 processing fee) that covers the boat.
Moving a boat you already own into the LLC
Transferring a boat you personally own into a new LLC is a change of ownership — new registration and title work at the DMV, and potentially tax. Connecticut’s DMV treats transfers for consideration as taxable sales; the recognized exceptions are narrow: a genuine gift (Gift Declaration AU-463, signed by the donor, with no consideration of any kind — cash, property, service, or assumption of debt — flowing back), and certain business organization, reorganization, or liquidation transfers that meet all four conditions on the DMV’s Form Q-20.
Read the Q-20 conditions closely before you count on them. As the DMV states them, the transfer must be in connection with the organization, reorganization, or liquidation of an incorporated business; the last taxable sale, transfer, or use must already have been subjected to Connecticut sales or use tax; the transferee must be an incorporated entity or a stockholder of the transferring entity; and no gain or loss may be recognized to the transferor under the federal income tax code. An LLC has members, not stockholders — so whether contributing a boat to your own LLC fits Q-20 at all is a genuinely open question on the face of the form. Put it to the DMV or a Connecticut tax professional before the transfer rather than assuming a paper move into your own LLC is automatically tax-free. And if the boat is financed, your lender’s consent comes first; buying through the LLC from day one is always cleaner than moving a boat in later.
Form the LLC in Connecticut — or Wyoming, Delaware, or Florida?
For a boat that lives on Connecticut water, the honest answer depends on why you’re forming the entity:
- The tax outcome is identical everywhere. The 2.99%, the DMV’s collection at registration, and the 60-day rules apply to the boat’s Connecticut use regardless of the formation state. No formation choice changes the DRS’s math — and at Connecticut’s rates, there’s less math than usual.
- Connecticut is the simple choice if you’re all-in local. The Certificate of Organization is $120, filed through Business.CT.gov, and the annual report is $80 — due every year in the January 1 – March 31 window for every LLC, not on your formation anniversary, which surprises owners expecting an anniversary date. Connecticut’s old $250 biennial Business Entity Tax was repealed effective 2020, so there’s no separate entity-level tax on top.
- Out-of-state formation buys entity-level advantages. A Wyoming LLC offers stronger privacy and lower ongoing cost ($60/yr minimum annual report vs $80); Delaware brings well-worn entity law for multi-partner boats. The trade-off: if the LLC’s Connecticut activity rises to transacting business here, a foreign registration in Connecticut may follow with its own fees — a facts-and-circumstances threshold that belongs with an attorney, not a formation checklist. A boat that merely floats here, on its own, is a genuinely gray case — get advice rather than assuming either answer.
Where FilingDesk fits
FilingDesk forms the holding LLC that will own your boat — describe what you need in plain English, we run the name check, prepare and file the paperwork, and a human specialist reviews every filing before it goes to the state — then handle your EIN and operating agreement. Flat $99 plus the state fee: Wyoming $199, Delaware $209, Florida $224 all-in, no upsells. Connecticut formation is on our roadmap.
We’ll also tell you what a formation service usually won’t: in Connecticut, the tax case for an exotic out-of-state structure is weaker than almost anywhere in the Northeast, because the state already took the deal — 2.99% on the boat, nothing on the yard bill, no sales tax on winter storage, no property tax while you own it. Form the entity for the right reasons — liability, co-ownership, privacy, succession — and keep the boat-specific steps (DMV registration, the AIS stamp, insurance) with you and your marine pros. When you’re ready, start your holding LLC.
