How Much Does It Cost to Register a Boat in South Dakota?
Registering a boat in South Dakota costs $35–$60 per year, based on length. It's handled by the county treasurer (SD Game, Fish & Parks rules) and renews annually. 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 | $35.00 | $10.00 |
| 20-ft motorboat | $60.00 | $10.00 |
| 28-ft motorboat | $60.00 | $10.00 |
| Kayak/canoe (no motor) | Free — exempt from registration | |
- Totals include the $3 admin and $2 technology fees ($30/$55 base). Non-motorized boats over 12 ft register for $18 base.
- Small non-motorized craft 12 ft and under are exempt from registration and title.
South Dakota: common questions
Do I have to register a kayak or canoe in South Dakota?
Generally no — unpowered craft are exempt in South Dakota. But the moment you mount any motor, including an electric trolling motor, registration is required.
How often do I renew a boat registration in South Dakota?
Annually.
Do I have to register my boat trailer separately in South Dakota?
Yes — in South Dakota 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 South Dakota trailer registration calculator for that cost.
Do I need a title for my boat in South Dakota?
Yes — South Dakota issues a boat title for a one-time $10 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 South Dakota?
Yes — personal watercraft (jet skis, Sea-Doos, WaveRunners) are motorized vessels, so they register just like boats in South Dakota, usually in the smallest length class. The same county treasurer (SD Game, Fish & Parks rules) handles them, and the same fee schedule applies.
Where do I register a boat in South Dakota?
Boat registration in South Dakota is handled by the county treasurer (SD Game, Fish & Parks rules). 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 year before your decal expires.
