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.
