What is VAT and Sales Tax?
Value Added Tax (VAT) and Goods & Services Tax (GST) are consumption taxes placed on products and services whenever value is added at each stage of the supply chain, from production to the point of sale. Sales tax, commonly used across US states, is applied directly at the final retail purchase.
