As of 2015, the sales and use tax in Minnesota is 6.875 percent, according to Hennepin County, Minnesota. Hennepin and other counties in the state assess additional local sales taxes on services and retail sales, such as a 0.15 percent ballpark tax and a 0.25 percent tax to improve transit.
Cities such as Bloomington and Minneapolis in Hennepin County also assess local taxes, notes Hennepin County, Minnesota. The Minnesota Department of Revenue offers a sales tax rate calculator on its website to help taxpayers compute the correct rates for local and state sales and use taxes. To use the calculator, taxpayers must submit the 9-digit ZIP codes for the sale locations and choose the sale time periods, according to the Minnesota Department of Revenue.
