How South Dakota works out this bill
South Dakota charges a 4% excise tax on the purchase price of a vehicle, instead of a sales tax. Registration is paid every year and depends on the vehicle's weight and age.
The excise tax is 4% of the purchase price on most motor vehicles. The credit or trade-in value allowed by the seller is deducted from the price.

For a vehicle bought outside the state, proof of tax paid is required when you apply for a title, and you may owe more tax.

License fees depend on the weight and year of the vehicle, and vehicles ten or more years old pay less.

Each example runs the same calculation as the calculator above. Local tax and county fees are left out unless the example says otherwise, because they depend on where you live. Estimates only.
What this calculator does not cover
- License fee amounts come from the department's staggered fee chart, dated 2015; the department says fees follow the weight and year of the vehicle.
- Plate mailing ($12) and registration mailing ($2.50) fees are not included.
- Registration is renewed in the month set by the first letter of the owner's last name; the first payment can cover more or fewer months than 12.
