Understanding the Latest Tax Rule Changes for Expats in Thailand

19th July 2024
As of January 1, 2024, significant changes to Thailand's tax regulations have come into effect, impacting all expats residing in the country for more than 180 days per tax year. These changes primarily concern the taxation of foreign-sourced income, which was previously exempt if brought into Thailand in a different tax year from when it was earned. Here’s a detailed summary of the new rules and what they mean for you.
Key Changes in Tax Rules

  • Taxation of Foreign Income: Under the new regulations, any foreign income brought into Thailand will now be subject to Thai personal income tax regardless of the year it was earned. This marks a significant shift from the previous rule where only income earned and brought into Thailand within the same year was taxable​.

  • Progressive Tax Rates: The tax rates applied to this income range from 5% to 35%, based on the total amount of income and existing personal income tax brackets​​.
  • Double Taxation Agreements (DTAs): Thailand has DTAs with 61 countries, which aim to prevent double taxation. If your income has already been taxed in another country, you can claim a credit for the tax paid abroad when filing your Thai tax return. However, it’s essential to understand the specific provisions of the DTA relevant to your situation as they can vary.

  • Tax Residency Definition: You are considered a tax resident of Thailand if you stay in the country for an aggregate period of 180 days or more in any given tax year. This status obligates you to declare and pay taxes on worldwide income brought into Thailand.

  • Compliance and Documentation: To comply with these new rules, expats need to obtain a Thai Tax Identification Number (TIN) and prepare detailed documentation of their foreign earnings and the taxes paid abroad. This includes income statements, tax certificates from the country of origin, and relevant bank statements.

Implications and Planning

These changes have substantial implications for financial planning:

  • Increased Tax Burden: Expats may face a higher tax burden due to the inclusion of previously untaxed foreign income. It’s crucial to calculate potential tax liabilities and plan accordingly.

  • Cashflow Modelling: At Brigantia Private Wealth Management, we have been conducting extensive cashflow modelling to illustrate the "before" and "after" scenarios. This helps provide clarity on how these changes will affect your specific financial situation.

  • Early Action is Essential: We strongly urge all our clients to review their financial arrangements immediately. Waiting until the last minute could result in penalties or missed opportunities for strategic tax planning.
