Some states (I'm not sure how many) have a sales tax; the end customer pays a percentage of the retail price of the item, in addition to the price itself. The sales tax in my state is currently 8.875 percent. (The seller must collect the taxes and send them to the government.)And what do Americans have then?
Although a sales tax and a value added tax are very different things. That is why you can get VAT refunded if you are a tourist, but if you ask for a refund of sales tax all you will get back is a puzzled look.I think saying vee-eh-tee is more common, particularly in more formal situations. In places where the term used is GST (goods and services tax) like Australia, Canada or Singapore, I might use that term instead; and to Americans I might just say sales tax.
