South Dakota Sales Tax Calculator
Figure the tax, the total, or the pre-tax price for any U.S. state or city rate
South Dakota levies a state sales tax of 4.2% on most retail purchases — a rate temporarily reduced from 4.5% in July 2023, set to revert in July 2027. On top of the state base rate, most cities and towns add a local sales tax of 1% to 2%, pushing the average combined rate to roughly 6.11% statewide, according to the Tax Foundation. Larger cities like Sioux Falls and Rapid City commonly reach a combined rate of 6.2%.
One important detail for shoppers: unlike many states, South Dakota taxes groceries at the full sales tax rate. Unprepared food for home consumption is not exempt — only purchases made with SNAP or WIC benefits escape the tax. Prepared food, candy, and soft drinks are fully taxable as well.
Worked example: Buy $100 worth of groceries in Rapid City. Apply the combined rate of 6.2%: $100 × 0.062 = $6.20 in sales tax, for a total of $106.20 at checkout.
To use this calculator, enter the purchase amount in dollars and set the rate to your local combined rate. If you're unsure, the 6.11% statewide average is a solid default. The result shows both the tax amount and the final purchase total — helpful for budgeting before you head to the register.
Practical example — South Dakota
A $250 electronics purchase in Sioux Falls at the combined 6.2% rate adds $15.50 in sales tax, bringing the total to $265.50 at checkout.

Some cities also levy a 1% gross receipts tax on specific services such as lodging and entertainment. Always check the rate for the specific city where a purchase is made.
Are groceries taxed in South Dakota?
Yes — South Dakota is one of the few states that taxes groceries at the full sales tax rate. Unprepared food for home consumption is subject to the 4.2% state rate plus any applicable local rate. The only exemption is for purchases made using federal SNAP or WIC benefits. Prepared food, candy, and soda are fully taxable.
Why did South Dakota lower its sales tax rate?
The South Dakota Legislature temporarily reduced the state sales tax from 4.5% to 4.2% effective July 1, 2023, to provide relief to consumers during a period of elevated inflation. The reduction is set to expire on July 1, 2027, at which point the rate will return to 4.5% unless the legislature acts to extend it.
What purchases are exempt from South Dakota sales tax?
South Dakota exempts certain items including prescription drugs, some medical equipment, and agricultural inputs like seeds and fertilizer. Groceries purchased with SNAP/WIC benefits are also exempt. However, most everyday retail goods — including clothing, electronics, and food — are taxable. Services are generally subject to sales tax as well, which is broader than many other states.
