What is VAT & Withholding Tax?

Value Added Tax (VAT) is a consumption tax added to goods and services at each stage of the supply chain. Withholding Tax (WHT) is tax deducted at source from payments like services, rent, or professional fees.

In Thailand, standard VAT is 7% and common WHT rates range from 1-5% depending on the service type. Understanding both helps you price correctly and comply with tax regulations.

Add VAT: Total = Amount × (1 + VAT/100) Remove VAT: Net = Amount ÷ (1 + VAT/100) WHT: Deduction = Base × (WHT/100) Net Received = Total − WHT
All values in same currency (USD, THB, EUR, etc.)
