Why the rate here is not the whole story
North Dakota charges 5 percent state sales tax, and both cities and counties may add a local sales, use and gross receipts tax on top, so the rate usually changes at a city limit rather than at the county line. Billings County levies no county sales tax of its own, so any address outside a taxing city pays the bare 5 percent state rate. One city in the county, Medora, imposes a city tax of 2.5 percent, which puts the highest combined rate in the county at 7.5 percent. North Dakota lets a city or county cap the local tax on a single transaction, and a buyer charged more than the cap can apply to the Tax Commissioner for a refund of the excess, so the effective local rate on a large purchase falls below the posted rate. Local rates change only on January 1, April 1, July 1 and October 1, and the department posts each change at least 60 days ahead. Use the department address lookup rather than a single county figure.
