Madison Sales Tax Rate — Economic Context & Calculation

The combined sales tax rate in Madison is 6.200%, composed of the South Dakota state rate of 4.200% plus a local portion of 2.000%. On a receipt, that stacks up as: 4.2% state rate + 2% City of Madison rate = 6.2% combined. SD has no state income tax. Groceries are fully taxable in South Dakota at the combined rate — one of the few states with no grocery break; a 2024 ballot measure to exempt them failed. DSU's cybersecurity focus makes it unique among SD universities.

For a $150.00 purchase in Madison: tax is $9.30 ($150.00 × 0.06200), total is $159.30.
