A Regulation for Employers in Thailand.

There is a regulation for employers in Thailand to deduct the withholding tax from their employee’s income every month.

For those income will be calculated to annual amount which is calculate by income times total payment period in one year.

In case of start working in the middle of the year will be calculated by income times total payment period in that year. For example, if start date on April, income will be times by 9 (April to December). Annual income will be in sum of monthly income and onetime payout to be the input of computation.

After getting the total amount of annual income will be calculated same as personal income tax, including those tax deduction and allowance. Then what come out is the personal tax for the annual period. That amount will be divided by the total period of the current year.

In case of increasing income during year, the theory of annual income still applied. The income will be times by total payment period and tax will also divided by the total payment period.

For onetime payment will not be considered to spread annually. The total amount will be subjected to deduct only for that certain payment period.
