Understanding Thai Tax as an Expat
Personal and business tax basics, explained simply.
You become a Thai tax resident for a calendar year if you spend 180 days or more in Thailand during that year, any part of a day counts as a full day. Your visa type does not matter: a retiree, a DTV holder, or a tourist on repeated entries can all become tax residents purely based on physical presence.
Since 1 January 2024, foreign-sourced income remitted (transferred) into Thailand by a Thai tax resident is potentially taxable, regardless of the year the income was earned. This closed the previous loophole of simply waiting a year before transferring funds. Income that stays in a foreign account and is never brought into Thailand is generally not taxed by Thailand.
As a Thai tax resident, you generally must file a personal income tax return if your annual assessable income exceeds THB 120,000 (single) or THB 220,000 (married couple), even if no tax is ultimately due. Returns are typically due by 31 March of the following year (8 April for e-filing). These thresholds and dates can change, always confirm the current figures with a professional before filing.
If you become liable to file or pay Thai tax, you'll need a Thai Tax Identification Number from the Revenue Department. Our partner can guide you through this process as part of a broader tax consultation.
Some foreign residents qualify for Thailand's Long-Term Resident (LTR) visa, which can offer an exemption on foreign-sourced income for qualifying categories (such as Wealthy Pensioners or Work-from-Thailand professionals). This is a separate track from company formation, ask our partner if it's relevant to your situation.
