What are the rates of withholding tax for an individual in Thailand?
At the end of each tax year, every taxpayer in Thailand must submit a tax computation to the Revenue Department, which should include their total annual income from all sources. The department uses this information to calculate the total personal income tax owed, considering any withholding tax already deducted throughout the year. Depending on the final calculation, an individual may be eligible for a refund or required to make an additional payment.
In Thailand, taxpayers can include their dividend or interest income in their taxable income while earning revenue. For your reference, here are the tax rates for individuals:
| Type of income | WHT Rate |
| Salary and wages | 0-35% |
| Provision of services | 0-35%. 15% if the recipient (foreigner) of the income is not a resident of Thailand. |
| Interest | 15% (of payment), |
| Rent | 5% (of payment), |
| Dividend | 10% (of payment), |
| Royalties | 0-35%. 15% if the recipient (foreigner) of the income is not a resident of Thailand. |

Nevertheless, certain income sources mandate withholding tax (WHT) payments, including.:
| Type of income | WHT Rate |
| Services provided | 3% of the payment |
| Interest | 1% of the payment paid to a Thai Company, 0% of the payment paid to a Thai Bank |
| Rent | 5% of all rental payments made; or 10% of rental payments made to associations and foundations |
| Income from liberal profession (e.g. laws, arts of healing, engineering, and architecture) | 3% of the payment |
| Income from payments to contractors who provide essential materials besides tools: | 3% of the payment |
| Royalties | 3% of the payment |
| Income paid by Government Agency | 1% of the payment |
| Income paid from the sale of goods | 0% of the payment |
What are the rates of withholding tax for Foreign companies that do not conduct business in Thailand?
Section 40 of the Revenue Code states that a foreign corporation receiving income in Thailand is typically subject to Thai Income Tax despite not conducting business there. Therefore, those making payments to these foreign entities are required to withhold income tax from their payments. Here are the key withholding tax rates based on the type of income received:
| Type of income | WHT Rate |
| Services provided | 15% of the payment |
| Interest | 15% of the payment |
| Dividends | 10% of the payment |
| Rent | 15% of the payment |
| Income from liberal profession (e.g. laws, arts of healing, engineering, and architecture) | 15% of the payment |
| Royalties | 15% of the payment |
However, there is a possibility that the withholding tax rate may be reduced if there is a double taxation agreement (DTA) between Thailand and the foreign country in question (see annexed list of contracting states).
a) Compared to other tax rates, the dividend tax payable is relatively low at 10%. This is due to the Thai government’s tax policy, which aims to avoid double taxation on dividends, as the Corporate Income Tax is already at a rate of 20%.
b) When a foreign company rents property to a Thai company, the latter is generally required to withhold tax at a rate of 15% on rental payments.
c) However, if the foreign company is conducting business in Thailand by renting property to a Thai company, the latter must withhold tax at 5% on the rent payment. Additionally, the foreign company is subject to a corporate income tax of 20% on its net profits from the rental business.
d) In most DTAs (such as the one between Thailand and Germany), the withholding tax rate on interest is reduced from 15% to 0% if the lender is a (German) bank. Similarly, the rate on capital gains is also reduced to 0% if the seller of a Thai company’s stock is a German company.
What are the withholding tax rates for Foreign companies conducting business in Thailand?
Foreign companies that conduct business in Thailand, such as having a branch office (read more: Set Up a Branch Office in Thailand), employment, representative, or intermediary in Thailand and earning income in the country, are typically subject to Thai Income Tax under Revenue Code Section 40. Consequently, payers to such companies are obligated to withhold income tax. The key withholding tax rates based on income categories are outlined below:
| Type of income | WHT Rate |
| Services provided | 5% of the payment |
| Interest | 1% of the payment |
| Dividends | 10% of the payment |
| Rent | 5% of the payment |
| Income from liberal profession (e.g. laws, arts of healing, engineering, and architecture) | 3% of the payment |
| Royalties | 5% of the payment. 3% of the payment if the foreign entity has a permanent branch office in Thailand |
Departmental Instruction No. Paw 8/2528 stipulates that a foreign contractor is deemed to have a permanent branch office in Thailand only if they meet the following conditions:
a) Own an office in Thailand, or
b) Conduct other businesses in Thailand in addition to the contract works, such as buying and selling goods, or
c) Set up a provident fund for the benefit of their employees in Thailand.
Typically, employees and employers establish the provident fund voluntarily to encourage savings so that employees who retire or are dismissed from work can support themselves without relying on state welfare or family.
At least one employer and one employee can establish the provident fund, and the law requires that a Fund Management Company that is neither the employer nor the employee manages the fund. Employee contributions are deducted from wages at a rate not less than 2% but not exceeding 15%.
In comparison, employer contributions are made at a rate not less than the employee’s contribution but not exceeding 15% of wages.
A withholding tax rate of 3% of the payment applies to income from royalties. Regarding the repatriation of profits, a withholding tax rate of 10% applies to payments made from the branch in Thailand to the foreign company.
In addition, foreign companies in Thailand must pay corporate income tax at a rate of 20% on their net profits from doing business in Thailand. Still, they may use the withheld tax as a credit against income tax.

How do you calculate withholding Tax?

What is a withholding tax certificate?
A withholding tax certificate in Thailand, also known as a P.N.D. 3 or P.N.D. 53 form, is a document that confirms the amount of withholding tax deducted from a payment made to a recipient.
