Sales tax in Ziebach County, South Dakota
There is no single sales tax rate in Ziebach County. It runs from 4.2% to 6.2% depending on the exact address, because South Dakota counties cannot levy a sales tax and the cities inside Ziebach County set their own. The 4.2% state rate applies everywhere in the county; everything above that depends on where you are standing.
What is the sales tax rate in Ziebach County?
| South Dakota state rate | 4.2% |
|---|---|
| Lowest combined rate in the county | 4.2% |
| Highest combined rate in the county | 6.2% |
The two combined figures are the lowest and highest totals found anywhere inside the county. They are not a state rate plus a county rate added together, and adding the rows above will not reproduce them, because cities and special districts levy in between.
Why the rate here is not the whole story
South Dakota's state sales tax is 4.2 percent and South Dakota counties have no authority to levy a general sales tax at all, so this county's own rate is a confirmed zero. Only incorporated municipalities may add one, capped at 2 percent by SDCL 10-52-2, and a city may start or change its rate only on January 1 or July 1. 2 municipalities in Ziebach County charge a municipal sales tax, the highest being 2 percent in Eagle Butte, so the combined rate runs from 4.2 percent in the unincorporated county to 6.2 percent at the top. The 6.2 percent ceiling comes from Eagle Butte, which the department lists under Dewey County but whose corporate limits cross the line so that roughly a seventh of the town sits in Ziebach County. Away from that town the highest rate in the county is Dupree's 1 percent, giving 5.2 percent, so print the ceiling only with this explanation. Most of Ziebach County lies inside the Cheyenne River Sioux Tribe reservation, which the department treats as a Special Jurisdiction under a comprehensive tax collection agreement. Sales there carry the same 4.2 percent rate, reported under the jurisdiction's own code and shared between the state and the tribe, and any municipal tax listed for a town inside it still applies, so the rate a buyer pays does not change. A separate municipal gross receipts tax of up to 1 percent applies to lodging, prepared food, alcohol and admissions in many South Dakota cities. It is a different tax and is not included in these figures.
