Costs of Business in Thailand - Taxation

Typically, we will advise our clients to analyze the potential costs of running a business in Thailand. Like all countries in the world, there are different types of costs required to run a business in Thailand. For this article, we will cover the Revenue Code Law in Thailand. The code covers three key segments: 1) Corporate Income Tax, 2) Value Added Tax (VAT), and Personal Income Tax.





1) Corporate Income Tax in Thailand


Corporate income tax in Thailand is a direct tax placed on a legal entity or partnership doing business in Thailand, or not doing business in Thailand but earning certain types of income there.


Thai & foreign entities operating their business in Thailand are required to file their tax returns (Form CIT 50) within 150 days from the closing date of their accounting periods. Tax payment must be submitted together with the tax returns. Any company transferring profits out of Thailand is also required to pay tax on the sum so disposed within 7 days from the transferred date (Form CIT 54).


In addition to the annual tax payment, any company subject to CIT on net profits is also required to make tax prepayment (Form CIT 51). A company is obliged to estimate its annual net profit as well as its tax liability and pay half of the estimated tax amount within 2 months after the end of the first 6 months of its accounting period. The prepaid tax is creditable against its annual tax liability.


Any income paid to foreign company not carrying on business in Thailand is required to be taxed. The payer must file the return (Form CIT 54) and make the payment to the Revenue Department within 7 days of the following month in which the payment is made.

Certain types of enterprises are exempt from VAT and will instead be subject to SBT (SBT). Taxable products are any tangible or intangible property that is accessible for sale, personal use, or any other purpose under the VAT regime. It also includes any articles that are brought into Thailand. Any activity carried out for the benefit of a person or an organisation that is not a delivery of products is referred to as a service.
