Why the rate here is not the whole story
Nebraska's state rate is 5.5 percent and local sales tax is levied almost entirely by cities and villages rather than by counties, at 0.5 percent up to 2 percent adopted at a local election under the Local Option Revenue Act. Dakota County is the only county in Nebraska levying a county sales tax, so Sioux County's own levy is a confirmed zero and the county line is not the tax boundary. The one incorporated place in Sioux County that charges a local rate is Harrison, at 1.5 percent, so the combined rate is 7 percent inside Harrison and 5.5 percent everywhere else in the county, including the unincorporated area and any village that has not adopted a tax. Nebraska rates change only on January 1, April 1, July 1 and October 1, and the department's Sales Tax Rate Finder is the only thing that answers the question for one address.
How do I find the exact rate for an address in Sioux County?
