VAT

What is VAT, and why does a business only pay over the difference?

GlossaryUpdated 11 October 2026

Definition

Value added tax (VAT) is a consumption tax charged at each stage of supply: businesses charge VAT on their sales, reclaim the VAT paid on their purchases and pay the difference to the tax authority.

What is VAT in practice?

Each business in a supply chain charges VAT on its sales, reclaims the VAT it paid on its purchases and pays over the difference, so the tax is borne by the final consumer. VAT-registered businesses must issue tax invoices, keep records and file periodic returns. Some supplies, such as many exports, are zero-rated, and some are exempt. Similar taxes elsewhere are called GST, as in India.

Rates and rules are set by each country. The UAE and Saudi Arabia both introduced VAT at 5% on 1 January 2018, and Saudi Arabia raised its rate to 15% from 1 July 2020. The two sides of the return are explained under input and output VAT.
