Achieving long-term success as a foreign entrepreneur in Thailand extends beyond successful business registration and securing the correct visas. A fundamental, and arguably more complex, pillar of sustainable operation is a thorough understanding of the kingdom’s tax system. Governed by the Thai Revenue Department, the tax landscape has several distinct layers that impact both your corporate entity and you as a foreign professional.
For any foreigner doing business here, comprehending these obligations is not optional—it is essential for legal compliance, financial health, and strategic planning. This guide provides a clear overview of the primary Thailand tax for foreigners to help you navigate this intricate maze.
Part 1: Corporate Tax Obligations (For Your Company)
Your Thai limited company is a distinct legal entity with its own set of tax responsibilities. The primary obligations include:
Corporate Income Tax (CIT): This is a direct tax levied on the net profit your company earns during its accounting period. Businesses are required to manage their CIT obligations twice a year: first through a semi-annual filing (Form PND 51) to pay an estimated tax for the first half of the year, and second with an annual filing (Form PND 50) to finalize the year’s tax liability. It is worth noting that companies with SME status may be subject to different progressive rates, and those with BOI promotion can benefit from significant corporate income tax exemptions.
Value Added Tax (VAT): VAT is an indirect tax applied to most sales of goods and provisions of services in Thailand. If your company’s annual revenue exceeds a legally defined threshold, VAT registration with the Revenue Department is mandatory. Once registered, your business is responsible for collecting VAT from its customers on every transaction and remitting it to the government on a monthly basis.
Withholding Tax (WHT): The concept of Withholding Tax is crucial for day-to-day operations. When your company makes certain types of payments (such as for rent, advertising, or professional services), it is legally required to “withhold” a portion of that payment and remit it directly to the Revenue Department. This system acts as an advance tax payment on behalf of the person or entity receiving the income, ensuring more consistent tax compliance in Thailand.
Part 2: Personal Tax Obligations (For You, the Foreigner)
Beyond your company’s taxes, you have personal tax duties as a foreign resident working in Thailand.
Personal Income Tax (PIT): Your liability for PIT is determined by your residency status. According to Thai tax law, any individual—regardless of nationality—who resides in Thailand for a cumulative period of 180 days or more in any calendar year is considered a “resident” for tax purposes.
- Taxable Income & The 2024 Rule: Thai residents are taxed on all income earned from sources within Thailand. Crucially, under a new rule effective from January 1, 2024, tax residency in Thailand now means that any income from foreign sources that is brought into the kingdom is also subject to Thai PIT. This is a significant change from previous regulations.
- Progressive Rates & Annual Filing: PIT is calculated using a progressive rate structure, where the tax rate increases as income rises. All tax residents are required to file an annual personal income tax return (using Form PND 90 or PND 91) by March 31st of the following year.
Double Taxation Agreements (DTA): To prevent individuals from being taxed on the same income twice, Thailand has entered into Double Taxation Agreements with many countries around the world. These treaties outline rules for determining which country has the right to tax different types of income, providing relief for expatriates from treaty countries.
Conclusion: Your Path to Full Compliance
Successfully managing your Thailand tax for foreigners is a dual responsibility that demands careful attention to both your company’s financial reporting and your personal income.
