Personal income tax is the money individuals are legally required to pay to the government. Paying taxes is a duty of Thai citizens because our income contributes to the nation’s overall revenue, which funds public services such as education, healthcare, and public utilities.
If your net income per year is less than 150,000 baht, you are exempt from tax.

The higher your income, the higher the tax rate you must pay according to the brackets.
