“Add tax” starts from a net price. “Remove tax” works backwards from a total that already includes tax. This is the STANDARD rate in Thailand — reduced rates, zero-rating and exemptions may apply to specific items. If you know a different rate applies to your item, type it into the rate field.

How to calculate Thailand VAT in 3 steps

  1. Enter your amount. Type the price you are working with — either before tax or tax-inclusive, depending on what you have.
  2. Pick the rate and direction. The 7% standard rate is pre-filled and editable; choose “Add tax” or “Remove tax”.
  3. Read the split instantly. You get the net amount, the exact tax, and the gross total — ready to quote, invoice, or check a receipt against.

Why getting the Thailand split right matters

Tax is the part of the price most people get wrong, because the headline rate is rarely the whole story: reduced rates, zero-rating and exemptions all change what applies to a given item. This calculator starts from the standard rate — and if your item qualifies for a different rate, type it in and it calculates that instead.
