South Dakota's 4.2% is temporary, and groceries are fully in
Two things make South Dakota unusual. First, the 4.2% state rate is not a permanent figure: it was cut from 4.5% under 2023 legislation and is scheduled to return to 4.5% after June 30, 2027 unless lawmakers extend the reduction. Anyone modeling costs into 2027 and beyond should treat 4.2% as provisional rather than fixed.
Second, South Dakota is one of the few states that taxes groceries at the full rate. There is no general food exemption; only purchases made with SNAP or WIC benefits escape the tax. So a grocery cart in Sioux Falls is taxed at the same 6.2% combined rate as a television, a meaningful difference from most neighboring states that exempt or discount food.
Local tax here is municipal, not county. Cities may add up to 2%, and most that levy it choose the full 2%, giving the common 6.2% combined rate. A few, such as Pierre with a 1% municipal rate, land lower at 5.2%. Importantly, municipalities can only change their rate on January 1 or July 1, so mid-year surprises are rare and the table below stays stable between those two dates. Prescription drugs are exempt statewide, which is the main relief in a state that otherwise keeps most goods, including food, inside the tax base.
