Until they will start taxing the worldwide income (soon)...Thailand is easy.
Do a Elite Visa, Investor Visa or other.
*Which investor visa? The LTR you mean? I can't find it. I see a youtube post that saying you need $300K in condos; but in any case - if exists - is it tax-free/exempt ?
No it's not. Depends on the country. And yes you are right for the wife but not the DTA. What the DTA has to do if you don't have any income from your citizenship country? And you only have from a third country. I think nothing to do. Am i wrong? Thank you!The certificate is worthless in most cases. Why? Because it is issued by the country that has low tax. You need to check the DTA details and what you other country may consider.
