Guides & Insights
Practical explainers on this topic: general information, not professional advice.
Tax & Accounting
Tax Identification Number in Thailand: How to Get a Thai TIN
A Thai national's ID card number is already their tax ID, and a company's DBD registration number is already its own. Who still has to apply, on which form, and inside which 60 days.
Tax & Accounting
How to File a Tax Return in Thailand: PND 90 and PND 91
Filing is triggered by how much you earned, whether or not any tax is due. Which form applies, the March and April deadlines, online versus paper, paying, refunds, and what late filing costs.
Tax & Accounting
Thailand Tax Residency and Income Tax for Foreigners
Thailand tax residency turns on 180 days in a calendar year, not on your visa. What that means for Thai income, foreign income, deductions and the rate you pay.
Tax consultants in Thailand handle the moves your accountant usually doesn't: cross-border structures, transfer pricing documentation, tax treaty relief, and Revenue Department audit response. They also run tax planning before a transaction or restructuring, not after the return is filed.
Hire a tax consultant when the stakes justify the cost: a material acquisition, a related-party transaction over 200 million THB, or a Revenue Department audit notice. Standard monthly compliance (VAT, withholding tax) usually stays with accounting services. The consultant comes in for the exceptions.
For corporate filing work (PND 50 and 51, BOI incentive claims, treaty applications), see corporate income tax. Personal income tax advice is separate and usually handled by the same accountant who does your payroll.
