Tax Losses

Tax losses incurred by a company can be carried forward for five years for corporate income tax purposes and for 10 years for petroleum income tax purposes. Tax losses cannot be transferred to related companies.

Withholding Taxes

Thailand has an extensive withholding tax system that requires withholding tax to be deducted from specified domestic and international payments, such as dividends, interest, rents and royalty payments.

Foreign Tax Credits

Thai-incorporated companies are entitled to claim a foreign tax credit for tax paid in a foreign country on income which is also subject to Thai corporate income tax. The foreign tax credit cannot exceed the amount of Thai corporate income tax payable on the income.

Transfer Pricing

Transfer pricing guidelines have been issued by the Revenue Department based on the arm’s-length principle, supplementing the requirements under Thai tax law for market-rate pricing in both related and unrelated party dealings.
