Frequently asked questions
Do I have to register a kayak or canoe in Iowa?
Yes — Iowa requires registration of unpowered craft as well. Adding any motor, including an electric trolling motor, always triggers the requirement.
How often do I renew a boat registration in Iowa?
Every 3 years — the fee shown covers the full 3-year period.
Do I have to register my boat trailer separately in Iowa?
Yes — in Iowa the boat and the trailer are two separate registrations. The boat's fee is above; the trailer registers as a utility trailer with the motor-vehicle agency, priced by the trailer's weight (often a low flat fee or a one-time permanent plate). See our Iowa trailer registration calculator for that cost.
Do I need a title for my boat in Iowa?
Yes — Iowa issues a boat title for a one-time $13.5 fee, generally required for larger or newer motorized vessels (smaller craft are often exempt). The title is separate from the registration fee shown above.
Do I have to register a jet ski or PWC in Iowa?
Yes — personal watercraft (jet skis, Sea-Doos, WaveRunners) are motorized vessels, so they register just like boats in Iowa, usually in the smallest length class. The same county recorder (Iowa DNR system) handles them, and the same fee schedule applies.
Where do I register a boat in Iowa?
Boat registration in Iowa is handled by the county recorder (Iowa DNR system). You can generally register in person, by mail, or online, and you'll need proof of ownership (a bill of sale or title) plus the fee shown above. Renew every 3 years before your decal expires.
