How to register a boat in Iowa
Register within 30 days of purchase
A new owner has 30 days after a private sale to register the vessel with the county recorder. The initial transfer of the boat into your name must be processed in the county where you reside; a nonresident registers in the Iowa county where the boat is principally used. Renewals can be done at any Iowa county recorder office.
Bring proof of ownership and the application
Complete the DNR Application for Boats, Snowmobiles, ATVs and ORVs (form 542-8067) and bring proof of ownership. For a brand-new boat that is a bill of sale plus the manufacturer's certificate of origin (MCO); for a used boat, bring the prior registration and the assigned title if the boat has one. Bring a photo ID.
Pay the fee and any tax
Pay the registration fee for your vessel's length class and type (see the fee table), plus the $13.50 title fee if the boat requires a title and another $13.50 if a lien is being recorded. Iowa charges 6% state sales/use tax (plus any local option tax) on the purchase price, collected at the time of registration.
Display your Iowa number and decal
The county recorder issues your Iowa registration number (an "IA" number) and a validation decal. The number must be painted or applied to the forward half of each side of the hull in bold, BLOCK characters at least 3 inches high, in a color contrasting with the hull. The current decal goes on each side toward the stern of the number, 4 inches from and in line with it.
Iowa registration fees
Iowa sets the registration fee by the boat's length class and type. Because registrations run in three-year cycles, the amounts below cover the full cycle. Personal watercraft, federally documented vessels, and boats with no motor or sail have their own flat rates. On top of the registration fee, add the $13.50 title fee for boats 17 feet and longer (and another $13.50 for a lien).
| Class | Vessel length | Base fee |
|---|---|---|
| Motor or sail — under 16 ft | Less than 16 ft | $28.15 |
| Motor or sail — 16 to 26 ft | 16 ft to less than 26 ft | $41.65 |
| Motor or sail — 26 to 40 ft | 26 ft to less than 40 ft | $80.65 |
| Motor or sail — 40 ft and over | 40 ft and over | $155.65 |
| Personal watercraft | Any length (jet ski / PWC) | $50.65 |
| No motor or sail | Non-powered craft that must register (e.g. canoe/kayak 13 ft+) | $17.65 |
| Federally documented vessel | Any length | $30.65 |
Full three-year-cycle base fees (the amounts published for the cycle beginning 1/1/25). A boat first registered partway through a cycle pays a reduced, prorated amount, and a $5.00 late penalty is added to renewals not completed by July 1. Confirm the current total — including the title fee, any lien fee, and a $2.00 surcharge for mail renewals — with your county recorder or the Iowa DNR boat-registration fee schedule.
Titling in Iowa
Iowa titles boats, but not all of them. A certificate of title is required for every boat 17 feet or longer (canoes and kayaks are excepted regardless of length), and for any boat of any size that has a lien recorded against it. Shorter boats with no lien are registered but not titled. The title is issued by the same county recorder that handles your registration, and the title fee is $13.50 (an additional $13.50 applies to record a lien).
A federally documented vessel is a separate case: the U.S. Coast Guard Certificate of Documentation is the ownership record, so Iowa does not issue a state title for a documented boat — but a documented vessel used on Iowa public water still must be registered with the DNR through the county recorder. This is the classic "documented but not state-titled" setup explained in state registration vs USCG documentation.
HIN requirements
A Hull Identification Number (HIN) is the 12-character code the manufacturer permanently affixed to the hull of any boat built after 1972. Iowa records that HIN on the registration and, where a title is issued, on the title, so the number on the hull must match the paperwork exactly before the county recorder can complete the transfer.
If a boat coming in from another state, a homemade boat, or an older boat has no HIN, a damaged or unreadable HIN, or a hull number that does not match its documents, the county recorder works with the Iowa DNR to verify or assign a state HIN before the vessel can be registered. Homemade and rebuilt hulls are the usual case for a DNR-assigned number.
Before you file, decode any existing hull number with the HIN decoder to confirm the manufacturer and model year match the bill of sale and the title — catching a transposed character on paper is far easier than untangling it after the record is created.
Renewal
Iowa boat registrations run on a three-year cycle, and every registration in the state expires on April 30 of the final year of the cycle — the current cycle runs May 1, 2025 through April 30, 2028. Renewal for the new cycle opens January 1 of that year, so you can renew several months before the April 30 deadline. Registrations not renewed on time carry a $5.00 penalty added beginning July 1; you cannot legally operate on public water on an expired registration.
Exemptions
Iowa exempts a narrow set of vessels from registration: inflatable vessels 7 feet or shorter with no motor or sail; canoes and kayaks 13 feet or shorter (including inflatable models) that have no motor or sail; vessels owned by a public school and used for research; and government search-and-rescue boats. Note the flip side — a canoe or kayak longer than 13 feet, or any craft carrying a motor or sail, is NOT exempt and must be registered.
Out-of-state boats get a reciprocity window: a nonresident may operate a vessel on Iowa public water for up to 60 nonconsecutive days per year while displaying a valid current registration from another state. Beyond that, the boat must be registered in Iowa.
Frequently asked questions
Do kayaks and canoes need to be registered in Iowa?
It depends on length. A canoe or kayak 13 feet or shorter with no motor or sail is exempt from registration in Iowa. A canoe or kayak longer than 13 feet must be registered, and so must any paddle craft that has a motor or sail attached. Registered non-powered craft pay a flat $17.65 fee for the cycle.
Does Iowa title boats?
Yes, but only some. A certificate of title is required for every boat 17 feet or longer (except canoes and kayaks) and for any boat that has a lien against it. Smaller boats with no lien are registered but not titled. Titling is done at the county recorder alongside registration, and the title fee is $13.50.
When does my Iowa boat registration expire?
All Iowa boat registrations expire on April 30 at the end of a three-year cycle — the current cycle ends April 30, 2028. Renewal opens January 1 of the expiration year, and a $5.00 penalty is added to renewals not completed by July 1.
Where do I register my boat in Iowa?
At the county recorder's office. The Iowa DNR sets the rules, but registration and titling are processed by the recorder in the county where you live (or, for a nonresident, the county where the boat is used most). You have 30 days after buying a boat in a private sale to register it.
Can I use my out-of-state boat in Iowa without registering it here?
For up to 60 nonconsecutive days a year, yes — as long as the boat displays a valid current registration from another state. If you exceed that window or become an Iowa resident, you must register the boat in Iowa.
