How to Register a Boat in Wisconsin: DNR Fees, the 16-Foot Title Rule and Transfers
How to register a boat in Wisconsin: DNR 3-year fees by length, the 16-foot title rule, Go Wild renewals, transfers and sales tax.

Learning how to register a boat in Wisconsin means dealing with one agency and two documents. The Department of Natural Resources (DNR) registers every motorized boat for three years, and a titling rule draws its line at exactly 16 feet: at that length or over, the boat also carries a certificate of title; under it, the registration card alone does the paperwork. Wisconsin's 617,000-plus registered boats are the fifth-largest fleet in the country. The national picture sits in our guide on how to register a boat — this page is the Wisconsin version.
Who Registers Boats in Wisconsin
The DNR administers boat registration and titling under Chapter 30 of the Wisconsin Statutes, and its boat registration page is the working source for every procedure below. Applications run online through the department's Go Wild system, in person at DNR service centers, or by mail on the Boat Registration and Titling Application (Form 9400-193), sent to the DNR Processing Center, PO Box 78701, Milwaukee, WI 53278-0701. Buy new and the dealer hands you the Manufacturer's Statement of Origin (MSO). Dealers who file for a customer must mail the application within seven days of the sale.
Which Boats Need a Wisconsin Registration
Every motorized vessel used on Wisconsin waters must be registered, whatever its size — an electric trolling motor makes a canoe a motorboat. Sailboats over 12 feet register too, motor or not. A boat registered in another state joins the system after more than 60 consecutive days on Wisconsin waters.
Outside the net, per the DNR: nonmotorized non-sailboats, sailboats of 12 feet or less and sailboards, visiting boats inside the 60-day window, foreign and public boats, ship's lifeboats, and race boats in the state no more than 10 days under permit. Exempt boats may register voluntarily for $11.
How to Register a Boat in Wisconsin: The 3-Year Fee Schedule
Wisconsin charges once for the whole three-year period — there is no annual bill. The DNR fee schedule scales with length and propulsion:
| Wisconsin boat registration fees — DNR schedule (3-year term) | Fee |
|---|---|
| Motorized boats — less than 16 ft | $22 |
| Motorized boats — 16 ft to less than 26 ft | $32 |
| Motorized boats — 26 ft to less than 40 ft | $60 |
| Motorized boats — 40 ft and over | $100 |
| Non-motorized sailboats (over 12 ft) | $17 |
| Voluntary registration (exempt boats) | $11 |
Read the table as the full three-year price: $22 keeps a small fishing boat legal for three springs, $60 runs 26 to under 40 feet, and the state's biggest cruisers pay $100 for the same term. A non-motorized sailboat over 12 feet pays $17, an exempt boat registered voluntarily $11. A federally documented vessel registers at the same length-based fee as any other boat. The DNR's small numbers: transfer $3.75, and a $1 issuing fee on each renewal.
When a Wisconsin Boat Title Is Required
Since February 1, 1989, the owner of a boat 16 feet in length or greater in Wisconsin has been required to hold a certificate of title — whether or not the boat is ever operated on state waters. The DNR's general information page states the exemptions: under-16 boats, voluntarily registered boats, nonresident purchases headed for another state's registration, and registration-exempt boats. A title costs $5 to issue, $5 to replace, and $5 to record a lien on.
Two precision points. First, the line sits at 16 feet, not above it: contrast Minnesota's registration guide, where the titling definition starts over 16 feet — a boat exactly 16 feet long is titled in Wisconsin and untitled in Minnesota. Second, a financed boat's lien prints on the title itself; before a title can pass to a new owner, the seller must satisfy it and hand over a release identifying the lien holder, the boat owner, and the hull identification number (HIN) or Wisconsin registration number.
Buying Used: Transfers, Titles and the 10-Day Rule
Wisconsin puts the deadline on the buyer. Under Wis. Stat. § 30.549, a sale terminates the old title and registration, and the buyer must apply for a new title and certificate of number within 10 days after the date of purchase. The seller's half is a hand-off: the registration card goes to the new owner, and so does the title on a titled boat.
- Titled in Wisconsin (16 feet and up): the seller signs the original certificate of title. If two owners are joined by "and," all must sign; if by "or," any one can.
- Under 16 feet (registered, never titled): no title exists to sign — the seller's registration card anchors the transfer; keep a written record of sale.
- Titled in another state: bring the original signed title. From a non-titling state, the seller's registration card does the same job.
- Never registered anywhere: a new boat files on its original MSO. A home-built boat substitutes materials receipts.
The fee for taking over the remainder of the seller's term is $3.75 — plus the $5 title issuance on a titled boat, $8.75 all-in. File online in Go Wild and you can print a 60-day temporary operating receipt and run the boat while the card and decals travel by mail — though on a 16-foot-plus boat, the signed title or MSO still follows by post before the file completes. File by mail and you wait for the new certificate and decals before legally operating, unless a DNR-authorized dealer submitted the application for you. Lien chains sit in our boat title transfer guide; an out-of-state boat can arrive with transportation providers, and owners moving on can sell your boat on the same marketplace.
The 3-Year Term, Renewals and Replacements
Registrations run on fixed springs, not your purchase date: the period begins April 1 of the year of issue and expires March 31 of the third year — a registration issued in 2026 runs to March 31, 2029. The DNR mails a renewal notice ahead of the deadline; renew online in Go Wild, in person, or by mail (Form 9400-622), paying the same length-based fee plus the $1 renewal issuing charge.
Losing the paper is cheap — replacement certificate $2.50, replacement decals $2.50, replacement title $5 — and the certificate and title travel in separate envelopes, so a thin delivery explains only half a missing set. Two habits keep the file clean: the certificate of number and the registration ride on one waterproof card carried on board, and state law gives you 15 days after a move to notify the DNR of your new address, so the next renewal notice finds you.
Sales Tax: 5% at the State Rate, Plus Where the Boat Is Kept
A 5% state sales tax must be collected for all nonexempt private-party and dealer sales — on a private sale you settle it with your registration application, not to the seller. County and city use taxes layer on top, keyed to where the boat is customarily kept: most counties levy one, and since January 1, 2024, a boat kept in the city of Milwaukee carries the city's 2% tax. Buy across the state line untaxed, and the same structure lands as use tax; keep the paid receipt in your file either way.
Documented Vessels and Visiting Boaters
A federally documented vessel skips the Wisconsin title, not the Wisconsin registration: it must register here if Wisconsin is its state of principal use or after 60 consecutive days on state waters, applying with a photocopy of both sides of its federal certificate of documentation. Documented boats display the two expiration decals either side of the vessel's name on the transom and need not paint on a state number. Titling a formerly documented boat instead takes the Coast Guard letter of deletion from the previous owner. Visiting boaters run on the same 60-day rule — inside it, a valid home-state registration carries the boat.
How to Register a Boat in Wisconsin FAQs
Does my kayak or canoe need a Wisconsin registration?
Not while it stays unpowered — nonmotorized non-sailboats are exempt, and so are sailboats of 12 feet or less. You may register voluntarily for $11. Add any motor — even an electric trolling motor — and the boat registers on the motorized ladder: $22 under 16 feet for three years.
How much does it cost to register a boat in Wisconsin?
One fee covers the full three-year term: $22 under 16 feet, $32 from 16 to under 26 feet, $60 from 26 to under 40 feet and $100 at 40 feet and over; a non-motorized sailboat over 12 feet pays $17. Boats 16 feet and longer add the $5 title issuance, and a transfer into your name costs $3.75 for the rest of the current term.
Does a Wisconsin boat under 16 feet need a title?
No. The titling requirement starts at 16 feet, so a shorter boat is registered but never titled; it sells on its registration card, which the seller must hand to the buyer under § 30.549, plus a written record of sale.
I bought a boat out of state and keep it at a Wisconsin lake house. What do I need?
Inside 60 consecutive days, your home-state registration carries you. Past that, the boat needs Wisconsin registration — and, at 16 feet or longer, a Wisconsin title. Apply in Go Wild or by mail with the out-of-state title (or its registration card, from a non-titling state), and expect the 5% state tax, plus any county or city tax where the boat is kept, to settle with the application.
Bottom line: how to register a boat in Wisconsin is one length-based fee, one three-year April-to-March term and one bright line at 16 feet — under it you register and sell on the card; at it and over it, you title too, and a buyer files within 10 days either way.
