If you stay over 180 days in a calendar year on a DTV visa, you become a tax resident. You must apply for a Tax ID Number and file an annual tax return. You pay personal income tax on income earned in Thailand and foreign income brought into Thailand. Double Taxation Agreements may offer credits to avoid paying tax twice.

We recommend you speak to our team to fully understand your personal tax situation. Book a call,  they will be happy to help.
