How much is car sales tax in South Dakota?
South Dakota charges a 4% motor vehicle excise tax instead of sales tax on vehicles, and no city or county sales tax is added on top.
If you buy from a licensed dealer, your trade-in comes off the price. If you buy privately, you pay 4% of the purchase price with no trade-in credit. A $1 'sale' is still a sale.
Title and lien notation are $10 each, plus a $2 technology fee. Registration adds $1 for solid waste and $1 for the Highway Patrol, along with a license fee based on weight, age and use. That fee comes from your county treasurer, as does any county wheel tax.
Electric vehicles charged from an external source pay $100 a year. If you title more than 45 days after purchase, interest and late title fees start; after 60 days a penalty of 10% of the tax (at least $10) applies.
- Dealer: taxable = price - trade-in; private: taxable = price
- Tax = taxable x 4%
- Total = tax + title + technology + lien + admin + solid waste + highway patrol + EV fee + license fee + wheel tax + mail fees + late charges + doc fee

Dealer purchase with a trade-in
You buy a truck from a South Dakota dealer for $28,000 and trade in your old vehicle for $8,000.
- Taxable amount: $28,000 − $8,000 = $20,000.
- Excise tax: $20,000 × 4% = $800.
- Add the $10 title and $2 technology fee: $12.
- Estimated total: $812, plus your county's license fee and wheel tax.
