In my case, I get dividends and rental income in Romania of course I have to pay tax on that income in Romania, but over a certain threshold I have to pay state health insurance. At 3 times the normal rate, unless I am tax resident in a different country.
Therefore I will be becoming a tax resident in Thailand to not have to pay that money.
I didn’t post this on the tax perspective, but more on the renewal process. ie easier to leave and come back rather than renew at immigration. Anyone in an official position I ask says dtv is just a posh tourist visa. So does a tourist have to pay tax???
