Value added tax (VAT)

Value added tax (VAT), or goods and services tax (GST), is tax on exchanges. It is levied on the added value that results from each exchange. It differs from a sales tax because a sales tax is levied on the total value of the exchange. For this reason, a VAT is neutral with respect to the number of passages that there are between the producer and the final consumer. A VAT is an indirect tax, in that the tax is collected from someone who does not bear the entire cost of the tax. To avoid double taxation on final consumption, exports (which by definition, are consumed abroad) are usually not subject to VAT and VAT charged under such circumstances is usually refundable.

VAT was invented by a French economist in 1954 as taxe sur la valeur ajoutée (TVA in French). Maurice Lauré, joint director of the French tax authority, the Direction générale des impôts, was first to introduce VAT with effect from 10 April 1954 for large businesses, and it was extended over time to all business sectors. In France, it is the most important source of state finance, accounting for approximately 45% of state revenues.^{[citation needed]}

Personal end-consumers of products and services cannot recover VAT on purchases, but businesses are able to recover VAT on the materials and services that they buy to make further supplies or services directly or indirectly sold to end-users. In this way, the total tax levied at each stage in the economic chain of supply is a constant fraction of the value added by a business to its products, and most of the cost of collecting the tax is borne by business, rather than by the state. VAT was invented because very high sales taxes and tariffs encourage cheating and smuggling. It has been criticized on the grounds that (like other consumption taxes) it is a regressive tax.
