How South Dakota Taxes Leases
Unlike buying, where you pay sales tax on the full negotiated price of the vehicle, leasing taxes vary wildly by state.
- Monthly Tax: South Dakota applies sales tax to each monthly lease payment. You only pay tax on the portion of the car you use.
A worked example for South Dakota
Take a $35,000 vehicle. Buying it in South Dakota means paying its 6.4% sales tax on the full price — roughly $2,240 in tax alone, due up front or rolled into your loan (where you also pay interest on it).
- Leasing instead spreads tax across your monthly payments, so you only ever pay tax on the portion of the car you actually use during the lease — typically a fraction of that $2,240.
These are illustrative figures. Registration, title, and documentation fees are extra and vary by county — confirm them with your South Dakota DMV or dealer.
