In Thailand, you need to file taxes if you live in the Kingdom for 180 days or more, or if the money was for work conducted in Thailand and your assessable income is over 120,000 THB as an individual or 220,000 THB as a joint filing married couple. The tax year is from January to December, and you usually have until the end of March the next year to file your taxes.
Do I need to register with the Thai Revenue Department if I have no income but stay over 180 days?
Yes. If you are in Thailand for more than 180 days in a calendar year, you are considered a Thai tax resident. Even if you have no current income, you should still obtain a Tax ID Number to ensure compliance. If you later remit income into Thailand, you will already be registered and ready to file.
