All but six states in the United States—Alaska, Delaware, Hawaii, Montana, New Hampshire, and Oregon—levy sales taxes in the United States on purchases. The amounts each state charges vary with some states even having a local sales tax in addition to a state sales tax. In some states the addition of the local tax can make the tax extremely high such as in New York State where the sales tax is only four per cent statewide, but in New York City, the combined tax is 8.375 per cent.
In addition to the percentages that the states charge, another difference lies in what is subject to sales tax. In some states sales taxes in the United States include everything you purchase, while others exempt medicines and non-prepared food items. In Pennsylvania, clothing and most footwear are also exempt from sales tax in the United States.
