VAT (Value-Added Tax) is a tax assessed to compensate services and infrastructure that were used in production and distribution processes and were provided by the state. The VAT tax raises about a fifth of the total revenue provided by the taxing system in most countries where it is implemented. Currently, 166 countries employ a VAT. The United States replaced the VAT with a sales tax system. In the European Union (EU). the VAT is obligatory by the EU VAT directive and is implemented in every country of European Union. Most countries also use reduced rates for VAT in order to liberate certain industries and encourage their development.
