Withholding Tax

Better understand Withholding Tax System & Calculation in Thailand


Withholding tax known as "WHT" refers to the deducting of tax from payments made by suppliers who provide services. The rates of withholding tax can be different depending on income, nature of the service and resident status. Withholding Tax also applies to interest and dividend payments in Thailand. Sending money to overseas suppliers could also result in a WHT deduction. Different rates apply to countries that have a double tax treaty in place with Thailand. However, no deduction is made for payments to non-taxpayers (e.g. the Government, BOI promoted company).

Dividends to a Thai company might be eligible for withholding taxes exemption if certain conditions are fulfilled under the Revenue Code, investment promotion law or investment code. Dividends to non-resident individuals and companies are subject to 10% tax. This tax may be reduced under a treaty. Interest paid to a nonresident company or individual will be subjected to 15% withholding tax, unless it is reduced by a tax treaty. Non-resident persons or companies pay royalties that are subject to a 15% final tax. These taxes can be reduced by a tax treaty.

The Withholding Tax deducted will be paid to Revenue Department within seven days after the month in the which the payment was made. For example, a payment to a supplier on the 28th of August 2018 will need the Withholding Tax deducted in order to be paid to the Revenue Department by September 7, 2018. The Revenue Department has announced that companies who have registered for efiling will be allowed an additional eight days in order to file their tax returns. This incentive will be available until 31 January 2024.

The fine for late submission is 100 baht within the first 7 days and 200 baht after 7 days. An additional penalty of 1.5% of the outstanding amount calculated monthly.

Consider a company making a THB 107,000 net payment to a Law Firm for its services. Taxes are at 3%. Withholding tax is calculated net from VAT, and the amount to be withheld would equal 3,000 THB (=3%) of Net. The final result is that the legal firm does not receive THB 107,000. Instead, it receives THB 114,000. Once the company submits its tax returns to the Revenue Department the withheld THB 3,00 will be added to the final tax liability. Effectively, clients pay the firm's corporate income taxes on their behalf. As proof of the deduction, the paye/company must also issue a tax certification to the firm. The main purpose of withholding is for Revenue Department to be able to collect the tax earlier than having to wait until the end.
