Correct. It's very easy for Australians to be dual tax residents of both Thailand and Australia. The steps are followed in the DTA to determine which country is the predominant one.
Not for Australians. The DTA contains a test process which determines which residency takes precedence when a dual residency exists. When this is done, pensions are dealt with under the laws of the respective country
I guess it depends on the DTA. I do know Australian pensions cannot be taxed in Thailand if the recipient retains Australian tax residency (which is easy to do).
I easily qualify for LTR, but why pay 50,000 instead of 10,000? That part doesn't add up. Paying 50,000 to avoid visiting immigration once a year also doesn't add up. I guess I've got better things to do with my money than throw it at Thai immigration. To each their own
Just as I tried to tell you a few days ago and you spouted the insults telling me that extensions would cost 10,000 baht every six months. Never mind. Your LTR visa now looks like crap.
