Sales tax in Butte County, South Dakota

By Brent Chudoba, editor Updated

There is no single sales tax rate in Butte 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 Butte County set their own. The 4.2% state rate applies everywhere in the county; everything above that depends on where you are standing. These rates were read from South Dakota's own published schedule and checked on September 9, 2026.

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. 3 municipalities in Butte County charge a municipal sales tax, the highest being 2 percent in Belle Fourche and 2 other cities, so the combined rate runs from 4.2 percent in the unincorporated county to 6.2 percent at the top. 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.

How do I find the exact rate for an address in Butte County?

Use South Dakota's own address lookup. In Butte County the rate depends on the address, anywhere from 4.2% to 6.2%.
