Thai and foreign companies doing business in Thailand are required to file their Corporate Income Tax returns (Form PND 50) within 150 days from the closing date of their accounting period. Tax payment must be submitted together with the tax returns. The deadline for payment is extended for a few more days if the company is registered with the Revenue Department’s online tax filing system.

In addition to the annual tax filing, any company subject to corporate income tax on net profits is also required to file its Interim Corporate Income Tax Return or Half-Year Income Tax (PND 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. For example, if the accounting period of the company is on December 31, PND 51 has to be submitted within August of the following year.
