Navigating Thailand’s tax system is crucial for expats. Here’s a concise guide on personal income taxes for foreigners in Thailand for 2024, updated to reflect the latest changes announced in September 2023.

Tax Residency

Criteria for Tax Residency:

  • A foreigner is considered a tax resident if they stay in Thailand for more than 180 days in a calendar year.
  • Tax residents are taxed on their worldwide income, whereas non-residents are taxed only on income earned within Thailand.

2024 Income Tax Rates

Thailand uses a progressive tax rate system. For 2024, the rates are:

  • Up to THB 150,000: 0%
  • THB 150,001 – THB 300,000: 5%
  • THB 300,001 – THB 500,000: 10%
  • THB 500,001 – THB 750,000: 15%
  • THB 750,001 – THB 1,000,000: 20%
  • THB 1,000,001 – THB 2,000,000: 25%
  • THB 2,000,001 – THB 5,000,000: 30%
  • Over THB 5,000,000: 35%

Filing Requirements

  • Tax Year: January 1 to December 31.
  • Filing Deadline: March 31 of the following year.
  • Penalties: 1.5% per month on the outstanding tax amount for late filing.

Deductions and Allowances

  • Personal Allowance: THB 60,000.
  • Spouse Allowance: THB 60,000 (if the spouse has no income).
  • Child Allowance: THB 30,000 per child (up to three children).
  • Education Allowance: THB 15,000 per child.
  • Parent Allowance: THB 30,000 per parent (if over 60 and earning less than THB 30,000 annually).

Double Taxation Agreements (DTAs)

Thailand has DTAs with many countries to prevent double taxation. These agreements allow expats to receive credit for taxes paid in Thailand against their home country’s tax liabilities. To understand the benefits and requirements, it’s essential to check the specific DTA between Thailand and your home country.

Taxation of Foreign Income

Critical Update for 2024:

  • For tax residents, foreign income is now taxable if remitted to Thailand, regardless of when it was earned. Any foreign income brought into Thailand in 2024 will be subject to Thai tax, even if earned in a previous tax year.

Social Security Contributions

Expats must contribute to the Thai Social Security Fund unless exempted. The contribution rate is 5% of the employee’s salary, capped at THB 750 monthly.

Practical Tips for Expats
