All these comments, clearly indicate that no one understands what Australians living long-term in Thailand or maybe what tax that will be...all speculation so far?
...It may well be that if my pension is free of taxation in Australia then the full amount I would be liable for in Thailand as the only tax is Thailand tax. So far nothing is really crystal clear and there are speculators galore on these sites. The USA and Australia have an agreement that you pay tax where you are domiciled in either USA or Australia. e.g. If you win the lotto in the USA, Americans do pay tax on gambling winnings if you are and American but if you are Australian you do not pay any tax...gambling winnings in Australia are tax-free unless you are a professional gambler. If an American wins the lotto in Australia that US taxpayer does pay US tax in their home country. If it was a $10,000.000 winnings tax maybe $3.000.000 for a US citizen back in the US would be payable.
If the funds are in the commercial area they will be taxed like any other income but if it is invested in a superannuation fund in Australia or in units spread across the AX 200 or Dow Jones, S&P 500 in the USA or other gilt-edged securities. or similar investments the tax by the Australian Govt is extracted before a dividend is paid It is free of any further tax. What you get now is tax-free. For low amounts of investments it may be better to be out of Superannuation but for wealthy people they may have to pay 47% in the dollar. I believe that occurs when your investment is over Aus $2 million dollars.
Well, perhaps there are a hundred different options worldwide if you invest your savings on international markets. that would be difficult and different for anyone but that is likely to affect and application you make for the Australian Aged Pension in Australia. or overseas. Good luck.
Well you get to spend the money Bt 500,000 if you like when you arrive in Thailand after you pay Bt10,000 to get the visa, you can renew your visa in Thailand after 6 months of that first year and the other 4 years is the same. As far as I can see you really have to be able to prove you're going to Thailand for a reason. Being a self-employed digital nomad seems to be already a popular reason, many posts on this site and other seems to be acceptable. but This is Thailand TIT.
The OA retirement visa is almost obsolete now. the Destination Thailand Visa (DTV) now will cost you Bt10,000 application proof that you have Bt500,000 in a bank anywhere outside of Thailand, you can spend it after you arrive in Thailand if you like than 4 border runs to anywhere or more than 4 extensions of cost Bt1900 each year and it's multi-entry. You must have a purpose for getting a DTV. Sound good to me.
It seems as a digital nomad you could apply for the new DTV and it will likely provided residency in Thailand for 5 years with just 4 visa nuns to Cambodia or similar for you and your wife over that time. It may be the best way to spend the money once you get the DTV and arrive in Thailand. The details are almost clear and simpler, a few months may make a retirement visa obsolete.... Things are happening and more soon is to come. The biggest change in Thailand's visas is about to happen.
If you do not advise Centrelink you going overseas the AAP supplement will stop the day you leave. If you give them a date you are going overseas that AAP supplement will stop after 6 weeks. You can give them a date you think you may return but that can be anything. After 6 weeks' absence from Australia, you will not be paid the AAP supplement until you return. Your residency in or out of Australia will register as soon as you go through immigration. Centrelink and Immigration are linked, they will know the moment you leave Australia.
