What you need to register a vehicle in South Dakota

South Dakota requires you to register any vehicle you own within 30 days of purchase or moving to the state. You'll register through your county treasurer's office, not a state DMV — each of South Dakota's 66 counties handles its own registrations. The process is the same across all counties, but office hours and wait times vary by location.

To complete registration, bring these documents to your county treasurer: proof of ownership (title, bill of sale, or manufacturer's certificate), proof of South Dakota residency (utility bill, lease, or mortgage statement dated within 60 days), a completed process for Certificate of Title and Registration (Form 2-69), and payment for registration fees. If you're registering a vehicle titled to someone else, bring a power of attorney or notarized consent from the owner.

You'll also need proof of insurance. South Dakota requires liability coverage of at least 25/50/25 (25,000 dollars bodily injury per person, 50,000 dollars per accident, 25,000 dollars property damage). Your insurance company can provide a declarations page or binder as proof — bring the original or a certified copy.

  • Bring your title or bill of sale, proof of residency, completed Form 2-69, proof of insurance, and payment for fees.
  • Registration fees depend on your vehicle's age and weight, and you can find the exact amount before you go by contacting your county treasurer.
  • Your registration is valid for one or two years depending on your vehicle type, and renewal notices are mailed 30 days before expiration.

Registration fees and what they cover

South Dakota registration fees are based on your vehicle's model year and gross vehicle weight rating (GVWR). Newer vehicles and heavier vehicles cost more to register. A passenger car typically costs between 50 and 150 dollars for a two-year registration, but the exact amount depends on the year and weight of your specific vehicle.

Your county treasurer can tell you the exact fee before you visit — call ahead or check their website. Some counties accept payment by phone or mail, which saves a trip. You'll also pay a one-time title fee (usually around 10 to 15 dollars) if this is your first registration in South Dakota or if you're transferring a title from another state.

Your registration covers two years for most passenger vehicles, though some vehicle types register for one year. When your registration expires, you'll receive a renewal notice in the mail about 30 days before the expiration date. You can renew by mail, online through some county treasurers' offices, or in person.

Registering a vehicle with a lien or loan

If you financed your vehicle, the lender holds a lien on the title. You can still register the vehicle, but the lienholder's name will appear on your registration certificate. Bring your loan documents or a letter from the lender showing the lien information when you register.

Once you pay off the loan, contact your lender to request a lien release. They'll send you a document showing the lien has been removed. Take this to your county treasurer to update your registration. Some lenders release the lien electronically, in which case the county treasurer can look it up in the state system — ask your lender which method they use.

Out-of-state vehicles and title transfers

If you're moving to South Dakota with a vehicle titled in another state, you must transfer the title to South Dakota within 30 days. Bring your out-of-state title, proof of residency, and completed Form 2-69 to your county treasurer. You'll pay a title transfer fee (usually 10 to 15 dollars) plus registration fees.

Some states issue electronic titles that the county treasurer can request directly from the other state's DMV. Others require you to mail the physical title to South Dakota. Your county treasurer will tell you which applies to your vehicle's state of origin — call before you visit so you know whether to bring the title with you.

If your out-of-state title is lost or damaged, you'll need a duplicate from that state before you can transfer it to South Dakota. This can take several weeks, so contact the other state's DMV as soon as you know you're moving.

Registering a vehicle you inherited or received as a gift

If you inherited a vehicle or received one as a gift, you'll need a title transfer document from the previous owner. For an inheritance, bring the will or a letter from the estate executor showing you're the new owner. For a gift, the previous owner must sign the title over to you — they can do this at the county treasurer's office with you present, or sign it beforehand and bring it with you.

Bring the signed title, proof of residency, completed Form 2-69, proof of insurance, and payment for registration and title fees. If the vehicle has a lien, the lienholder must also sign off on the transfer, which usually requires a letter from them.

Duplicate registration certificates and plates

If your registration certificate or license plate is lost, stolen, or damaged, you can get a replacement from your county treasurer. Bring your driver's license or other photo ID and payment for the replacement fee (usually 5 to 10 dollars for a certificate, 10 to 15 dollars for a plate). Replacement plates typically arrive within one to two weeks.

If your plate is stolen, file a police report first and bring a copy to the county treasurer. Some counties waive the replacement fee if you have a theft report. If your registration certificate is damaged but still readable, some counties will replace it at no charge — ask when you call.

Frequently Asked Questions

Can I register my vehicle online in South Dakota?

Some county treasurers offer online renewal for vehicles that are already registered in South Dakota, but initial registration and title transfers must be done in person or by mail. Check your county treasurer's website to see if online renewal is available in your county. Mail-in registration is also an option — call your county treasurer for the process and required documents.

What happens if I don't register my vehicle within 30 days?

Driving an unregistered vehicle in South Dakota is illegal and can result in a fine. If you're stopped by law enforcement, you may be cited. If you've missed the important date, register as soon as possible. The county treasurer won't charge a late fee, but you should not drive the vehicle on public roads until it's registered.

Do I need to register a vehicle I'm only keeping temporarily?

If you own the vehicle, you must register it even if you plan to sell it soon. If you're borrowing a vehicle from someone else, the owner is responsible for registration. If you're buying a vehicle and plan to drive it home before the paperwork is complete, ask the seller for temporary tags or a bill of sale to show law enforcement if you're stopped.

How do I register a vehicle with an out-of-state title that has a lien?

Bring your out-of-state title showing the lien, a letter from the lienholder confirming the lien, proof of residency, completed Form 2-69, proof of insurance, and payment for fees. The lienholder's name will appear on your South Dakota registration. Once you pay off the loan, get a lien release from the lender and take it to your county treasurer to update your registration.

What if my vehicle is registered to a business or trust?

Bring the business license or trust documents along with the title, proof of the business or trust address in South Dakota, completed Form 2-69, proof of insurance, and payment for fees. If you're registering on behalf of the business or trust, bring a power of attorney or notarized authorization showing you have the right to register the vehicle.
