Thailand

Thailand is a major lifestyle and business base in Southeast Asia. For internationally mobile individuals, the key tax feature is that Thailand does not generally tax foreign-sourced income unless it is brought into Thailand, but the rules have tightened for income earned from 2024 onward.

Thailand personal income tax is progressive up to 35%. Dividends from Thai companies are generally subject to 10% withholding. There is no standalone capital gains tax for individuals; many gains are treated as assessable income and taxed at ordinary rates depending on the asset and facts.

For Thai tax residents (commonly triggered by 180 days or more in a calendar year), foreign-sourced income earned from 2024 onward is taxable if it is remitted into Thailand, even if the remittance occurs in a later year. Foreign income that is not remitted is generally not taxed in Thailand. Income earned before 1 January 2024 is generally excluded from the newer remittance rule under official guidance.

Thailand is accessible through a wide range of visas and long-stay options (including membership-style long-stay visas), but visa status and tax residency are separate. In practice, planning hinges on clearly documenting the source and year of foreign funds and checking treaty relief where relevant.
