One of the questions our clients ask us the most is how much tax rate to use when calculating Corporate Income Tax in Thailand.

The corporate income tax rates depends on the amount of capital and its net income during the year. To explain it further:

1. If the company has less than THB 5 million capital and has less than THB 30 million income, the tax rates to be used are as follows:-

Tax Rate

First THB 300,000 = 0%

300,001 – 3,000,000 = 15%

Over 3,000,000 = 20%

2. If the company has more than THB 5 million capital and even if they decrease it later, it is fixed to 20% every year as long as the company is existing.

3. If the company has more than THB 30 million income and if the income decreases next year, it is also fixed to 20% as long as the company is existing.

Make sure your accounting and taxes are done properly and be mindful of the deadline for submission of corporate income tax and audited financial statements. Contact MSNA for consultation on Thai taxes and filing of requirements for your company in Thailand.
