Thai Personal Income Tax

There are 2 types of taxpayers in Thailand for personal income tax. They are “resident” and “non-resident”. The term “Resident” would explain any individual who is residing in Thailand for a period of more than 180 days in any calendar tax year. This person would be liable to pay income tax on income from sources in Thailand as well as on the portion of income from foreign sources which enters Thailand. The “non-resident” is taxable on from sources in Thailand.
