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. Blue Earth County itself levies a 0.5 percent Blue Earth Transit sales tax, which reaches every address in the county. Mankato and North Mankato each add a city tax of their own on top, and the highest combined rate in the county is 7.875 percent in Mankato and North Mankato. 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.
