消费税
Sales tax is calculated by multiplying the purchase price by the applicable tax rate. The seller collects it at the time of the sale. Use tax is self-assessed by a buyer who has not paid sales tax on a taxable purchase. Unlike the value added tax, a sales tax is imposed only at the retail level. In cases where items are sold at retail more than once, such as used cars, the sales tax can be charged on the same item indefinitely.
