My answer refers specifically to men with Thai partners. And in this case, I am drawing up a will that benefits my partner.But that doesn't change the fundamental problem. How do you live in Thailand when there is no capital available? And there are more than one example of failed existences in Thailand. The golden days of gross for net are over when Thailand takes tax advantage of capital. That is why many people are now feeling uncertain.
If your income is taxed in Australia, this will not happen. Australia also has a double taxation agreement with Thailand. Just read the terms and conditions there. 35% tax would only be due on income of 5 million baht. 30% on 2-5 million, 25% on 1-2 million, etc. So don't let it drive you crazy. At the moment there is just a lot of hot air.
