How to calculate Minnesota sales tax
Multiply the price by the combined rate. At the 6.875% state rate, a $250.00 sale carries $17.19 of sales tax, for a total of $267.19. Add the county, city or district rate for the delivery address to get the full rate for that sale.
To find the tax inside a total that already includes it, divide the total by 1 plus the rate. A $107.00 receipt at 6.875% is $100.12 before tax and $6.88 of tax.
