The purpose of withholding tax in Thailand is to reduce to burden of the taxpayer and not have to pay a lot of tax at once at the end of the year.

Let’s look further into withholding tax.

Withholding tax is the deduction of tax from payments made to suppliers who provide a service. The withholding tax rates can vary depending on the types of income and the status of the resident.

Expenses are required to withhold tax

Expenses that require the deduction of withholding tax are:

  • Expenses of more than THB 1,000
  • Expenses less than THB 1,000 in the case that a long-term contract is in place (ie telephone or internet bills)

The withholding rates for Thai residents are as follows:

ServiceWithholding tax rate

Dividends paid to a non-resident company and individual are also subject to 10% withholding tax which may be reduced under a tax treaty.

Calculation of withholding tax in Thailand

Suppose a company is making a THB 107,000 gross payment to a legal firm for its services (taxed by the rate of 3%).

Since withholding tax is calculated net of VAT (Net = THB 100,000), the amount to be withheld will account for 3,000 THB (=3% of Net). In the end, instead of getting paid THB 107,000, the legal firm receives only THB 104,000 and the withheld THB 3,000 will be credited against its final tax liability once submitted by the company to the Revenue Department.

Effectively, the clients of the legal firm pay its corporate income tax on the firm’s behalf. The company/payer is also required to issue the legal firm a tax certificate as a proof of the deduction.

In essence, the whole point of withholding tax is for the Revenue Depart to able to collect the tax from liable entities in advance instead of having to wait until the end of financial the year.

When is withholding tax due?

Companies withholding tax for other firms, employees or other entities have a duty of submitting the withholding tax to the Revenue Department within the first seven days of the following month in which the payment was made.

Late submission penalties

Failure to submit the tax returns to the Revenue Department on time will result in a fine of THB 100 within the first seven days after the deadline and THB 200 after the first seven days of the deadline.

An additional penalty of 1.5% of the unpaid amount will also be charged each month.

Withholding tax relief measures in response to COVID-19

The Ministry of Finance released the Ministerial Regulation (No.361) on 27 March 2020 to provide guidelines for the withholding tax relief.

The withholding tax imposed on certain payments will be reduced from 3% to 1.5% from 1 April 2020 to 30 September 2020.

The withholding tax will be reduced from 3% to 2% from 1 October 2020 to 31 December 2021 if the payment is made through the e-withholding tax system.

The withholding tax reduction, however, will not be applicable to payments made to charitable foundations and associations.

The types of income based on the Thai Revenue Code that are eligible for the 2% withholding tax relief through the e-withholding tax are:

  • Income derived from a performance or work, meeting allowance, gratuity, house rent allowance, bonus, the monetary value of rent-free residence provided by a payer of income, etc. (section 40 (2))
  • Only income derived from goodwill, copyright and other rights in a similar nature as royalty (section 40 (3))
