Do I have to file taxes in Thailand if I stay more than 180 days?

If you do not like to pay any tax than the solution is stay not more 170 day's in one country. Example. Go 30 day's holiday and 170 day's in your country and 170 day's in Thailand and live the tax free life !

Yes

No

Only if you have an income in Thailand 🇹🇭

Just leave Thailand go for a day trip to Malaysia and your 180 days start again

If you become tax resident in Thailand then you are required to file a tax return only if you have assessable income above certain minimal thresholds. The requirement to file a tax return has not changed. It has always been the case for tax residents. For this year you should have filed your return for 2023 by 1st April or electronically by 9th April. From 1st Jan 2024 the interpretation of what is assessable income was modified by the Revenue Dept. That is all that happened.

you can ask to be issued a Thai Tax ID number from the revenue department on your location. But you don't have to file anything before January 1st, 2025. The annual tax for 2024 then needs to be declared until May 30th, 2025

Tax will start for 2024 calendar year. So nothing to report for 2023 even if you did stay there more than 180 days in 2023.

You need to consult a Thai tax expert not a Facebook group. Everyone's financial situation is different.
