Taxes in Thailand: rates and deadlines
The five taxes every Thai company deals with, and the monthly and yearly filing deadlines for each.
Taxes in Thailand are collected mainly by the Revenue Department (RD). In its first year, a Thai company deals with five of them: value added tax (VAT), the tax invoice rules that support it, withholding tax (WHT), corporate income tax (CIT) and personal income tax (PIT) on its employees’ salaries. Each card below summarizes one of them and links to the full guide.
Value added tax (VAT)
VAT is charged on most sales of goods and services in Thailand. The rate is 7%, a reduced rate extended to 30 September 2027 (the statutory rate is 10%). Exports are taxed at 0%, and some activities are exempt. Registration is mandatory once annual turnover exceeds THB 1.8 million.
Tax invoice
A tax invoice is the document a VAT-registered seller must issue for each sale. The buyer needs it to claim back the input VAT it paid, so a missing or incorrect tax invoice costs your customer money.
Withholding tax (WHT)
WHT is deducted at source by the payer when paying for services, rent, advertising and other items. Between Thai companies the rate is usually 1% to 5%, depending on the type of payment. The payer files it with the RD and gives the supplier a WHT certificate.
Personal income tax (PIT)
PIT is charged at progressive rates from 0% to 35%. Tax residents, meaning individuals who stay in Thailand 180 days or more in a calendar year, pay PIT on Thai-source income and on foreign income they bring into Thailand. Non-residents pay PIT on Thai-source income only.
Corporate income tax (CIT)
CIT is charged at 20% on the net profit of companies incorporated in Thailand, and of foreign companies that do business in Thailand or receive income from Thailand. Small companies pay 0% on their first THB 300,000 of net profit and 15% up to THB 3 million.
