I get a lot of questions regarding Tax Residence. Folks want to know about Tax Residence and we are going to get into this a little bit. Now understand one's factual situation is going to drive the analysis regarding tax residence. Do not take this video as dispositive or as the end all be all with respect to your specific case. If you are worried about your tax residence in Thailand, it is probably a good idea to contact a legal or tax professional or accounting professional to gain some insight and guidance into how to deal with that or your overall status. 

We went ahead and pulled this from the Revenue Department, that is rd.go.th, and this is under Taxable Person, quoting directly: "Taxpayers are classified into "Resident" and "Non-resident". “Resident” means any person residing in Thailand for period or periods aggregating more than 180 days in any tax, that is calendar year. A resident of Thailand is liable to pay tax on income from sources in Thailand as well as on a portion of income from foreign sources that is brought into Thailand. A “non-resident” however is subject to tax only on income from sources in Thailand." So again, there is some discrepancy there and when you get into sources abroad you have to look at the timing. There is a lot of nuance in the analysis regarding offshore income; offshore earnings; things like capital gains and things. It really is a good idea to get some insight from a tax professional here in Thailand as to how exactly this applies to you. Generally speaking and the thing to take away from this is the number of days, just have it in the back of your mind, is 180 days.

For those who again they feel worried about their taxable situation, especially foreign nationals who have substantial assets abroad, it may be a good idea to go ahead and contact a legal professional, gain some insight and guidance as to the situation in your case.
