What You Need to Register a Vehicle in South Dakota
South Dakota requires you to register your vehicle with the Department of Revenue before you can legally drive it on public roads. Registration is handled through your county treasurer's office, not a state office. You will need a completed Form 14-1 (process for Certificate of Title and Registration), proof of ownership, proof of South Dakota residency, and a valid photo ID. If the vehicle is financed, you will also need the lender's information.
The state requires a vehicle inspection before first registration if the vehicle is new to South Dakota or if you are registering it for the first time. You can have the inspection done at any authorized inspection station — your county treasurer can direct you to nearby locations. Bring the vehicle's VIN, current odometer reading, and proof of insurance to the inspection.
Registration fees in South Dakota are based on the vehicle's age and type. A passenger vehicle typically costs between $40 and $80 for a one-year registration, though the exact amount depends on the model year. Trucks, motorcycles, and other vehicle types have different fee schedules. Your county treasurer's office can quote the exact fee before you pay.

How to Register a Vehicle You Just Bought
If you purchased a vehicle in South Dakota, the seller should provide you with the title document and a bill of sale. Take both documents to your county treasurer's office along with your completed Form 14-1. The treasurer will verify ownership, collect the registration fee, and issue your registration certificate and license plates. This process typically takes one business day if you have all documents in order.
If you bought the vehicle from a private seller and the title is in their name, you will need their signature on the title transfer section. If the title is held by a lender, the lender must sign off on the transfer. Your county treasurer can explain what signatures are required based on your specific title document.
If you purchased the vehicle out of state, bring the out-of-state title, bill of sale, and proof that you now live in South Dakota. South Dakota will issue a new title in your name. You will still need the vehicle inspection before registration is complete.
Registering a Vehicle You Inherited or Received as a Gift
If you inherited a vehicle, bring the title, a copy of the will or probate court order showing you as the beneficiary, and your completed Form 14-1 to your county treasurer. The treasurer will transfer the title into your name. If the vehicle is financed, the lender's name will remain on the title even after the transfer.
For a vehicle received as a gift, the giver must sign the title transfer section. Bring the signed title, a bill of sale (which can be a straightforward written statement signed by both parties showing the date and vehicle details), and your Form 14-1. Gift vehicles are still subject to the standard registration fee and inspection requirement.
Documents You Will Need at the County Treasurer's Office

| Form 14-1 | process for Certificate of Title and Registration | Your county treasurer's office or the South Dakota Department of Revenue website |
| Title or ownership proof | The current title document or bill of sale from the seller | The seller or previous owner |

License Plates and Registration Stickers
When you register your vehicle, South Dakota issues you a set of license plates and a registration sticker. The sticker goes on your windshield and shows the month and year your registration expires. You must display both the plates and the sticker while driving.
If you need replacement plates because yours are damaged, lost, or stolen, contact your county treasurer's office. Replacement plates cost around $10 to $15. If your registration sticker is damaged or missing, the treasurer can issue a replacement at no charge.
South Dakota does not require you to return old plates when you register a new vehicle or move out of state. However, if you sell your vehicle, the new owner will need to register it in their name and receive new plates.
Renewing Your Registration
Your registration is valid for one year from the date it is issued. About 30 days before expiration, the county treasurer will mail a renewal notice to the address on file. You can renew by mail, in person, or online through the South Dakota Department of Revenue website, depending on your county's options.
To renew by mail, fill out the renewal form included in the notice, include proof of current insurance, and mail it with the registration fee to your county treasurer. Processing by mail typically takes one to two weeks. Renewing in person at the treasurer's office is faster — usually same-day — and you can pay the fee when ready.
If your registration expires before you renew, you cannot legally drive the vehicle until it is renewed. Driving with an expired registration can result in a traffic citation. If you miss the renewal important date, contact your county treasurer about late renewal options.
Special Registration Types in South Dakota
South Dakota offers several registration options beyond standard annual registration. Temporary permits are available if you need to drive a vehicle before registration is complete — for example, if you just bought a vehicle and are waiting for the inspection appointment. Temporary permits are valid for up to 30 days and cost around $10.
If you own a vehicle that is rarely driven — such as a classic car or seasonal vehicle — you may be able to register it as a seasonal vehicle. Seasonal registration is available for shorter periods and costs less than a full-year registration. Contact your county treasurer to learn whether your vehicle qualifies and what the fee would be.
Vehicles used for commercial purposes, such as taxis or delivery vehicles, require commercial registration, which has different fee structures and may require additional documentation. If your vehicle is used for business, ask your county treasurer whether commercial registration applies to you.
Frequently Asked Questions
Can I register my vehicle online in South Dakota?
Some counties allow online renewal for vehicles already registered in South Dakota, but new registrations and title transfers must be done in person at your county treasurer's office. Check your county treasurer's website to see whether online renewal is available in your area.
What if I move to a different county in South Dakota?
You do not need to re-register your vehicle if you move within South Dakota. Your registration remains valid until the expiration date. When you renew, you can renew through your new county treasurer's office, and they will update your address on file.
Do I need insurance before I register my vehicle?
South Dakota requires proof of liability insurance to register a vehicle. You must show proof of current insurance at the time of registration. If your insurance lapses, your registration can be suspended, so keep your policy active.
What happens if I register a vehicle with a lien on the title?
You can register a vehicle even if a lender holds the title. The lender's name will appear on the registration and title documents. You own and can drive the vehicle, but the lender has a legal claim until the loan is paid off. When you pay off the loan, the lender will release the lien and you can request a new title in your name only.
How much does it cost to register a vehicle in South Dakota?
Registration fees depend on the vehicle's age and type. A one-year passenger vehicle registration typically costs between $40 and $80. Trucks, motorcycles, and other vehicle types have different fees. Your county treasurer can provide an exact quote based on your vehicle's year, make, and model.
