Boat Taxes by State: Sales and Use Tax, Yearly Property or Excise Tax, Visiting Limits and Moving

Taxes follow where the boat is kept (its "situs") and sometimes where you live. Call or check the websites of three offices:

• State boating or titling agency (often a DMV, wildlife agency or county tax collector acting as its agent): registration, title and any tax collected at registration.
• State revenue department: sales and use tax rules for boats, exemptions, and any statewide boat excise tax.
• County or city assessor / commissioner of the revenue: yearly personal property tax, filing deadlines and how boats are valued.

Ask each one: "What do I owe when I register a boat I just bought, and what will I owe every year?"

• Sales tax is charged by a dealer at the sale.
• Use tax is the same idea for purchases where no sales tax was collected: a private sale, an out-of-state purchase, or an online purchase. It's commonly collected when you title or register the boat.

In a private sale there's usually no one collecting tax at the handshake, but that doesn't make the sale tax-free. Nassau County, Florida, for example, says sales tax will be collected when a used boat is transferred, if applicable, and new boats need proof of tax paid or proof of an exemption.

The tax is based on the price (or a book value), so the bill of sale matters:

• Write the true price. Under-reporting it is illegal. In Florida, for example, the sales tax law makes reporting a lower price than you paid on an occasional sale a first-degree misdemeanor, and the party owes the missing tax plus a penalty of twice that amount. (The same paragraph lets the state tax a low-priced used car on a pricing-guide value; that pricing-guide rule is written for motor vehicles, so ask the tax collector how it values a boat.)
• List the trailer separately from the boat and motor. Texas Parks and Wildlife, for example, asks for the trailer price to be shown separately on a handwritten bill of sale, because trailers are handled by a different agency.
• Keep receipts for any tax already paid, especially to another state.

Late registration often adds penalties and interest. Two examples: Texas requires title transfer applications within 45 working days of purchase or tax penalties and interest apply, and the California DMV handbook lists a 10% use tax penalty if fees and use tax aren't paid within 30 days of the transfer. Your state's deadline may be shorter or longer, so ask on day one.

Many states charge use tax on a boat bought elsewhere and brought home, and give credit for tax paid to the selling state. The California DMV handbook shows how this works: if you paid 5% in the other state and your California rate is higher, you pay the difference. If the selling state charged nothing (a private sale), you may owe your home state's full rate. Our out-of-state buying guide covers the rest of the trip home.

Some states give nonresidents an exemption if the boat leaves the state quickly, and some buyers try to time deliveries or offshore trips to avoid tax. These exemptions come with strict conditions. Florida's law, for example, ties its exemption for nonresidents buying through a registered dealer to removing the boat within a set number of days (10 days in the basic case; a dealer-issued decal can allow up to 90 days for qualifying larger boats, with one extension to a 180-day maximum), providing proof such as out-of-state fuel or dockage receipts, and a sworn affidavit. A buyer who doesn't meet the conditions, or brings the boat back within six months, owes the use tax plus a penalty equal to the tax. Texas has a similar idea: the Comptroller lists a tax-free purchase only if the boat leaves the state within 10 days, or within 90 days with a paid temporary use permit. If anyone suggests a tax-saving delivery plan, get it reviewed by a tax professional before you sign.

Ask your county or state:

• Is there a yearly property tax or excise tax on boats, and on motors and trailers?
• What's the tax day (often January 1) and the filing deadline?
• How is the boat valued (a pricing guide, purchase price, or a depreciation schedule)? Loudoun County, for example, uses a used trade-in value from a marine pricing guide; Washington uses a depreciation schedule set in state rules.
• Is it prorated if you buy or sell mid-year? Washington prorates new registrations; Roanoke County does not.

Put the number in your yearly budget (our ownership budget guide has a line for it).

Your home-state registration lets you boat in another state for a while, but not forever:

• Federal law says a state must recognize your registration while you're temporarily operating there, and when a boat moves to a new state of principal use, that state honors the old number for 60 days (33 CFR 173.17).
• States set their own visitor periods. Florida, for example, lets nonresident pleasure boats with valid out-of-state registration use its waters for 90 days before they must register there.

Staying past the visitor period can trigger registration, and registration can trigger use tax or a yearly tax. If you plan a long season away (a winter in the South, a summer up north), ask the destination state before you go.

• Register in the new state within its deadline (the federal 60-day recognition is a ceiling, not a guarantee of more time).
• Ask whether use tax applies to a boat you already own and used elsewhere. Some states exempt boats owned for a certain time before the move or give credit for tax paid; others don't. Bring proof of what you paid and when. Two examples as of October 2026: the Texas Comptroller lets a new Texas resident pay a flat $15 new resident tax instead of the 6.25% use tax on a boat they bring with them, and Virginia Tax bases its 2% watercraft tax on current market value instead of price when a boat bought 6 months or more earlier first has to be titled in Virginia. Rules like these change, so ask the new state's revenue department.
• Tell your old county you've moved the boat so it stops billing you, and keep that confirmation.
• Update your address with the registration authority (our registration guide covers number and decal changes).

Coast Guard documentation is a federal record of ownership and nationality, not a tax exemption. BoatUS notes that some states still require documented boats to keep a state registration, and that every owner must follow state law and pay applicable state taxes. Because a documented boat may never pass through the DMV, the tax can land on you directly: California's tax agency (CDTFA), for example, says use tax on a documented vessel is paid straight to CDTFA, while the DMV collects it for undocumented boats at registration. Ask your state how it handles documented boats (and see our guide to buying a documented boat if the documentation has lapsed).

Keep the bill of sale, tax receipts, registration records and yearly tax bills together. They answer questions if a state or county audits the purchase, and they help the next buyer and their state when you sell.
