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 Clark County charge a municipal sales tax, the highest being 2 percent in Bradley 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.
