Corporate Income Tax In Thailand

From 2017 Thailand's corporate income tax has been set at 10 to 20 percent of net profit. All juristic companies and partnerships registered in Thailand are subject to income tax on the revenues earned from within and outside of Thailand. If you have a branch of a foreign company in Thailand you are subject to corporate income tax on the revenues earned inside of Thailand.

Generally foundations will pay income taxes at a rate of 2 to 10 percent of gross revenues depending on the type of income. The foundations and associations mentioned by the notification of the Ministry of Finance as a public charity organization are exempt from income tax.

      International transport companies pay an income tax rate of 3 percent of gross ticket receipts with 3 percent of gross freight charges.

Your annual tax return must be filed by the taxpayer within 150 days from the accounting year-end. Every accounting period is 12 months except for newly incorporated companies. Returns must be filed together with audited financial statements.

A corporate taxpayer must also file a half-year tax return paying 50% of the estimated annual income tax by the end of the 8th of that accounting year. Failure to pay this (including underpayment) by more than 25% may subject you to a fine up to 20% of the amount in deficit.

Double taxation treaties between Thailand foreign countries will cover taxes on income and the capital of individuals and juristic entities.
