If I stay for 90 days in Thailand, then fly out to Malaysia for a week, then I repeat the above process 1 more time in a year ,
, and I do this every year, do I still need to pay tax to Thailand ?
TLDR : Answer Summary
If you stay in Thailand for 90 days, then spend a week in Malaysia before returning, you will repeat this cycle. It is important to note that if you accumulate 180 days or more in Thailand within a year, you may qualify as a tax resident. However, whether you owe taxes depends on your specific income situation and any applicable double tax treaties. Some individuals, such as retirees or those who earn income outside Thailand, might not be subject to Thai taxes even if they meet the residency threshold.
