Why the rate here is not the whole story

Minnesota's state rate is 6.875 percent and local sales taxes are not automatic. A city or a county has to get specific authority from the Legislature and then win a local referendum, so the local layer is assembled one jurisdiction at a time and the county line is frequently not the tax boundary. Martin County itself levies a 0.5 percent Martin Transit sales tax, which reaches every address in the county. Fairmont adds a city tax of its own on top, which is why the rate reaches 7.875 percent there and sits at 7.375 percent elsewhere in the county. Clothing is exempt from Minnesota sales tax at every rate shown here, which is unusual among states and changes none of the rates. Use the department's Sales Tax Rate Calculator for a specific address rather than a single county figure.
