The 2 main types of tax that are levied on the INDIVIDUAL are Personal Income Tax (PIT) and Withholding Tax (WHT), which are important to note when you’re doing business in Thailand. In the previous article we discussed that there are various rates of tax charged depending on the individuals income, where it is generated from as well as their personal status.  The varying rates and rules for both of these taxes are dealt with in greater detail below.

Personal Income Tax (PIT)

PIT is a direct tax levied on an individual.  The taxpayer who is doing business in Thailand is liable to pay this to the Revenues Department as well as filing a tax return on an annual basis.  Taxpayers are classed as either “resident” and “non resident”.  For tax purposes a resident is anyone living in Thailand for more than 180 days each year.  A resident is liable for tax earned in Thailand via their business, as well as a portion of income earned from foreign sources and brought into Thailand.  A non resident is liable for income earned in Thailand only.

Taxable income is calculated in the following manner: Assessable Income minus Deductions minus Allowances.  Details of Deductions and Allowances are given below (source:

PIT is a progressive tax, basically meaning the more you earn, the higher the amount of tax that you will pay in a similar manner to most western countries.  The rates are relatively easy to understand as most people will be familiar with the practice.  Earned income between THB0 – THB150,000 is tax exempt; income between THB150,001 – THB500,000 is charged  at 10%; THB500,001 – THB1,000,000 is charged at 20%; THB1,000,001 – THB4,000,000 is charged at 30% and any amount over and above this is charged at 37%

 Withholding Tax (WHT)

WHT for the individual is somewhat easier to calculate.  The tax is generally taken at source at a rate of between 5 and 37%.  The payment should be made to the District Revenue Office and shall be credited against the individual PIT liability at the time of filing.
