What is Sales Tax?
Sales tax is a consumption tax imposed by the government on the sale of goods and services. In the United States, sales tax is usually collected by the retailer at the point of purchase and then passed on to the state or local government. Unlike many European countries where VAT is included in the sticker price, US prices are almost always listed "pre-tax."
