  2. Fill in the allowances you have; the 60,000 personal allowance is taken off by itself. Leave the rest empty or 0.
  3. Read the tax for the year, the tax a month and the take-home pay. The tables below show where the numbers come from and what each bracket costs.

Questions and answers

How is Thai personal income tax for 2569 (2026) worked out?

Take the year's income, deduct 50% expenses (up to 100,000) and the allowances (60,000 personal, social security, funds, insurance) for the net income, then apply the 0–35% brackets. The tool shows each step.

How is the net monthly salary worked out?

Salary less 5% social security (at most 875 baht in 2569), less the provident fund at the % you set, less the tax the employer withholds, spread over the months. Real payslips can differ a little.

Can I file my taxes with these numbers?

They are an estimate for planning, not tax advice. Some allowance ceilings have extra conditions; the Revenue Department (rd.go.th) and its filing system are what count. Nothing is sent or kept.
