How to work out South Dakota sales tax
Add the state rate and your local rate to get the combined rate. Then:
- Tax on a price: price × combined rate. At 4.2%, $100 carries $4.20, so you pay $104.20.
- Tax inside a total: total ÷ (1 + combined rate) gives the price before tax. The difference is the tax.
Some goods are taxed at a different rate or not at all, such as groceries in many states. Check the state's page for the item you're pricing.
