South Dakota Sales Tax Guide

South Dakota charges a 4.2% state sales tax on most retail purchases, and it is unusually broad: the rate reaches not just tangible goods but a wide range of services, which many other states leave untaxed. On top of the state rate, cities can add a municipal sales tax of up to 2%, and some also levy a 1% municipal gross receipts tax on lodging, prepared food, and similar categories. That means the total you pay at a register in Sioux Falls or Rapid City typically runs above the bare 4.2%, depending on the local add-ons in that town.

South Dakota gives fewer everyday exemptions than most states. Prescription drugs are exempt, but groceries are not carved out the way they are in many neighboring states, so food bought to prepare at home is generally taxable at the full rate. The South Dakota Department of Revenue administers the tax and collects it through sellers. The state also enforces a companion use tax: when you buy from an out-of-state or online seller that does not charge South Dakota tax, you owe the same rate directly, which keeps a remote purchase from undercutting a local store on tax alone.

South Dakota Sales Tax FAQ

What is the sales tax rate in South Dakota?
The state rate is 4.2%, applied to most retail sales of goods and many services. Municipalities can add a local sales tax of up to 2%, plus a possible 1% municipal gross receipts tax on things like lodging and prepared food, so the combined rate at checkout varies by city and usually exceeds 4.2%. The South Dakota Department of Revenue administers the state portion.
Are groceries and medicine taxed in South Dakota?
Prescription drugs are exempt from South Dakota sales tax, but groceries generally are not. Unlike several neighboring states, South Dakota taxes most food bought for home preparation at the full state rate, plus any local add-on. That broad base, including the tax on many services, is part of how the state funds itself without a personal income tax.
Do I owe tax on something I bought online or out of state?
Yes, through South Dakota's use tax. If an out-of-state or online retailer does not collect South Dakota sales tax on a taxable item you bring into or use in the state, you owe the equivalent rate directly to the Department of Revenue. Many large online sellers now collect it automatically, but where they do not, the obligation to report and pay falls on the buyer.
Why does South Dakota tax so many services compared to other states?
South Dakota applies its 4.2% rate to a broad list of services, not just physical goods, which is less common nationally. With no personal income tax, the state leans heavily on a wide sales tax base for revenue, so things like certain professional and personal services that escape tax elsewhere can be taxable here. The exact treatment depends on the service category, which the Department of Revenue defines.
