Add state + county + city sales tax to any price, or reverse-calculate the pre-tax price from a total. Supports bulk quantity calculations and shows each tax portion separately.
Sales tax in the US is collected at the state, county, and city level — and combined rates vary from 0% (Oregon, Montana, New Hampshire, Delaware, Alaska) to over 11% in some Louisiana and Tennessee cities. Five states have no sales tax at all. When calculating backwards from a receipt total, always divide — never subtract — to find the true pre-tax amount.
