Withholding Tax in Thailand

Withholding Tax ?

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.

*****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 Withholding Tax?

Withholding Tax does not apply to amounts less than THB 1000. However, you are required to deduct this Thai tax whatever the amount if you are linked by a long-term agreement to the service provider. Withholding tax therefore applies when you pay phone or internet bills of your company.

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

The fine for late submission is:

  • 100 baht within the first 7 days

  • 200 baht after 7 days
