About My Thai Taxes

My Thai Taxes is a free online calculator and information resource designed to help individuals understand and estimate their Thai personal income tax obligations. Whether you are a salaried employee, freelancer, sole proprietor, or company director, the tools here are built to walk you through Thailand's tax system in plain language — without requiring an accounting background.

Thailand's personal income tax rules can be confusing, especially for expats and digital nomads navigating the 180-day residency rule, foreign income remittance requirements, and the range of allowances available to reduce taxable income. This site exists to make that process clearer and more accessible.
