The value added tax (VAT) revolution began in the 1950s and has since expanded to over 170 countries. Designed as a consumption tax, VAT is widely recognised as an efficient revenue-generation mechanism, contributing approximately 35% of total tax revenues worldwide. It is also considered more conducive to economic growth and easier to administer than other forms of taxation. A well-designed VAT system has a broad base, minimal exemptions, a single rate, and an administratively feasible registration threshold. Effective implementation requires self-assessment, digital compliance mechanisms, robust refund systems, and efficient tax administration.
