What you need to register a car in South Dakota
To register a car in South Dakota, you need to visit your county treasurer's office in person with your vehicle title, proof of identity, and proof of residency. The treasurer's office handles all vehicle registration — not the DMV, which South Dakota does not have. You will pay a registration fee based on your vehicle's age and weight, and you will receive your registration certificate and license plates on the same day or within a few days.
South Dakota does not require an emissions test or safety inspection before registration, which makes the process faster than in many other states. However, you must have a clear title to the vehicle, meaning no liens or claims against it, or you must bring proof that any lien has been satisfied.
Key Takeaways
- Registration happens at your county treasurer's office, not a state DMV office, and you must go in person with your title and ID.
- You will need proof of South Dakota residency, such as a utility bill or lease agreement dated within the last 60 days.
- Registration fees depend on your vehicle's model year and gross vehicle weight rating, not on its value or condition.
- You receive your registration certificate and license plates the same day or within a few business days, so you can drive legally when ready after paying.
- South Dakota does not require emissions testing or safety inspections before you can register.
Documents to bring to the treasurer's office
Bring your vehicle's title — the original document showing ownership. If the title is in someone else's name, you will need a bill of sale signed by the previous owner, or a power of attorney if someone else is signing on your behalf. If the title has a lien on it (meaning a bank or lender still owns part of the vehicle), bring proof that the lien has been paid off, such as a letter from the lender or a release of lien document.
Bring a government-issued photo ID, such as a driver's license, passport, or military ID. Bring proof that you live in South Dakota, dated within the last 60 days. A utility bill, lease agreement, mortgage statement, or bank statement with your name and current address will work. If you just moved to South Dakota and do not yet have a utility bill in your name, a signed lease or rental agreement is usually accepted.
If you are registering a vehicle that is new to you, bring the bill of sale or purchase agreement showing the price you paid. This helps the treasurer's office verify the transaction and calculate any applicable taxes.
Registration fees and what they cover
South Dakota registration fees are based on your vehicle's model year and its gross vehicle weight rating (GVWR), not on the vehicle's value. A passenger car typically costs between $60 and $100 per year, depending on its age. Trucks and heavier vehicles cost more. The treasurer's office will tell you the exact fee when you arrive with your vehicle information.
Your registration fee covers your registration certificate (the paper document) and one set of license plates. If you need a second set of plates, there is an additional charge. If you are registering a vehicle with a salvage title or a branded title (such as a flood-damaged or rebuilt vehicle), the fee may be different, and the treasurer's office will explain this when you explore.
South Dakota does not charge sales tax on vehicle registration itself, but you may owe sales tax on the vehicle purchase if you bought it from a dealer. The treasurer's office can explain whether sales tax applies to your transaction.
How to find your county treasurer's office
Each of South Dakota's 66 counties has its own treasurer's office. Search online for "[your county name] South Dakota treasurer" to find the office address, phone number, and hours. Most offices are open Monday through Friday during standard business hours, though some have limited hours on certain days. Call ahead if you want to confirm they have received your documents or if you have questions about what to bring.
Some counties allow you to mail in your registration if you have already obtained your title and other documents, but most require you to appear in person. Call your county treasurer's office to ask whether mail-in registration is an option in your county.
What happens if your vehicle has a lien
If you are financing your vehicle through a bank, credit union, or dealership, the lender's name will appear on the title as a lienholder. You can still register the vehicle, but you must bring proof that the lien has been satisfied (paid off) before the treasurer will issue your registration. This proof is usually a letter from the lender stating that the loan is paid in full, or a release of lien document signed by the lender.
If you are still making payments on the vehicle, you cannot register it in your name alone. The lender must either sign the title or provide a power of attorney allowing you to register on their behalf. Contact your lender to ask what documents they need to provide. Some lenders will mail the release directly to the treasurer's office, which speeds up the process.
Renewing your registration each year
South Dakota registration is valid for one year from the date you register. Before your registration expires, you will receive a renewal notice in the mail from your county treasurer's office. You can renew by mail, online, or in person. To renew by mail, send the renewal notice with your payment to the address shown on the notice. To renew online, visit your county treasurer's website — most counties now offer this option.
If you renew online or by mail, you do not need to bring your vehicle or appear in person. Your new registration certificate will arrive by mail within a week or two. If you renew in person at the treasurer's office, you will receive your new certificate the same day.
Registering a vehicle you just moved to South Dakota with
If you moved to South Dakota from another state and already have a vehicle registered in your previous state, you must register it in South Dakota within 30 days of establishing residency. Bring your out-of-state title, your new proof of South Dakota residency, and your ID to your county treasurer's office. The treasurer will issue you a South Dakota title and registration.
You do not need to return your old license plates to your previous state — you can keep them as a souvenir or dispose of them. South Dakota will issue you new South Dakota plates. If your out-of-state title has a lien on it, follow the same process as described above: bring proof that the lien has been satisfied, or contact your lender to arrange for them to release the lien.
Frequently Asked Questions
Can I register a car online in South Dakota?
You cannot complete your initial registration online — you must visit your county treasurer's office in person with your title and ID. However, you can renew your registration online in most counties. Check your county treasurer's website to see if online renewal is available in your area.
What if my title is lost or damaged?
Contact your county treasurer's office. They can issue a duplicate title if you provide proof of ownership, such as a bill of sale or previous registration. There is a small fee for a duplicate title, usually around $10 to $15.
Do I need a South Dakota driver's license to register a car here?
No. You need proof of South Dakota residency (such as a utility bill or lease) and a government-issued photo ID, but your ID does not have to be a South Dakota driver's license. An out-of-state license, passport, or military ID will work.
How long does registration take on the day I explore?
The process usually takes 15 to 30 minutes at the treasurer's office, depending on how busy they are. You will receive your registration certificate and plates the same day in most cases, though some counties may mail your plates to you within a few days if they are out of stock.
What if I bought a vehicle from a private seller and do not have a title yet?
Contact your county treasurer's office before you visit. If the seller lost the title, the treasurer can help you obtain a duplicate from the previous owner's county. This process takes longer than a standard registration, so ask about the timeline and what documents you will need.
