How Much Does It Cost to Register a Boat in Missouri?
In Missouri, boat registration is handled by the Missouri Department of Revenue and renews every 3 years. The fee is based on boat length — from $25 for the smallest class up to $150 for the largest per cycle. Non-motorized craft like kayaks and canoes are generally exempt (check local rules for sailboats). Boats with motors — including trolling motors on otherwise unpowered craft — almost always require registration.
Cost by boat size
| Boat | Per year | One-time (title etc.) |
|---|---|---|
| 14-ft motorboat | $8.33 | $7.50 |
| 20-ft motorboat | $18.33 | $7.50 |
| 28-ft motorboat | $33.33 | $7.50 |
| Kayak/canoe (no motor) | Free — exempt from registration | |
- Add a $9 processing fee per transaction; outboard motors title/register separately ($5 + $2 + processing).
- Paddle/oar craft of any length and sailboats 12 ft and under are exempt. All registrations expire June 30 of the decal year.
