Withholding Tax in Thailand

Withholding tax (“WHT”) is a deduction from payments made to suppliers who provide a service. Whether WHT is applicable and what rate to deduct depends on the nature of the service provided.

WHT also applies to interest and dividend payments.

Remittances made to overseas suppliers may also incur a WHT deduction.

Countries with a double tax treaty with Thailand have different applicable rates.

How to calculate

The following will require the deduction of WHT:

  1. Expenses greater than 1,000 Baht; and
  2. Expenses less than 1,000 Baht for which a long term contract is in place (e.g. telephone)

However, no deduction is made for payments to non-taxpayers (e.g. the Government, BOI promoted company).
