Taxable Person

In order to understand what is Income Tax (PND 90, 91, 94), we have to clarify what is a taxable person in Thailand as personal income tax is the tax on income of a person.  The Thai Revenue Code defines a person as an individual, an ordinary partnership, a non-juristic body of persons and an undivided estate, a deceased person for their assessable income and estate throughout the year in which death occurred. A person is liable to personal income and therefore must compute, file and pax tax according to the calendar year deadlines.

Any person, Thai or foreign, who resides in Thailand for a period or periods aggregating to a period of 180 days or more in any tax (calendar) year will be regarded as a resident of Thailand for tax purposes. A resident of Thailand is liable for personal income tax on income from sources inside Thailand and on assessable income derived from sources outside Thailand. However, the imposition of tax on income derived outside Thailand will apply only to income derived and brought into Thailand in the same year in which such income is earned. A non-resident is subject to pay tax only on income from sources within Thailand irrespective of the place of payment. Click here to find more details from Thailand Revenue Department.
