Thai tax residents are liable for tax on foreign sourced income if remitted to Thailand. From January 1, 2024, new tax rules apply to income from outside Thailand. If you’re a Thai tax resident and you bring in more than 120,000 THB (or 220,000 THB for married couples) from foreign retirement income to Thailand, you will need to file a Thai tax return. You do get Thai allowances and deductions, and can potentially use tax paid on that retirement income as a tax credit against tax owed in Thailand, but this depends on the specific DTA between the jurisdiction where your retirement pension is based and Thailand.
