What does VAT and GST mean?

Value added tax (VAT) and goods and services tax (GST) are taxes on sales that a business collects from customers and passes to the government. VAT is used in the UK, the European Union and several Gulf countries, including the UAE and Saudi Arabia; India and Singapore use GST. The US uses state and local sales taxes instead. Reported revenue excludes these taxes, so check whether a price you are given includes them.
