How to sell a boat in South Dakota
A boat bill of sale identifies the vessel by its Hull Identification Number (HIN), covers the motor and trailer if they are part of the deal, and records the price and date. Most states register boats through the wildlife or parks agency rather than the DMV, and nearly all of them accept a signed bill of sale as proof of purchase.
Seller steps
- Confirm you hold clear title. If a lender is on the title, get the lien release before you list it.
- Agree on the price and fill in the South Dakota boat bill of sale above with the buyer. Record the HIN.
- Both parties sign and each keeps a copy. South Dakota does not require a notary.
- Sign the title over to the buyer exactly as your name appears on it, and complete the odometer section on the title if the boat has one.
- Hand over the boat and keep your signed copy of the bill of sale for your records.
Buyer steps
- Bring the signed bill of sale (or South Dakota's Form 1025), the signed title and your ID to the South Dakota Department of Revenue.
- Expect to pay sales or use tax on the price shown on the bill of sale, plus title and registration fees.
- Register within South Dakota's deadline, commonly 10 to 30 days from the sale date, to avoid late penalties.
Before you sign
- The HIN is on the transom (back right corner), 12 characters.
- List the outboard motor separately with its serial number; motors are often registered or titled on their own.
- If a trailer is included, add its VIN; the trailer is titled through the DMV, not the boat office.
- Note whether the sale includes electronics, life jackets or other gear.
Why a bill of sale matters for a boat
- Boats, motors and trailers can be three separate pieces of property; one bill of sale ties them to one sale.
- The state boat registration office needs the price for tax.
- Many used boats have no title; the bill of sale is the ownership chain.
- An as-is clause matters more on boats, where hidden hull or engine damage is common.
