f you go to live in Thailand on the Australian Aged Pension (AAP) you will receive from Centrelink about Bt 620,000 per year or about Bt12,000 per week (Aus $27,000 per year). You can rent a condo in Hua Hin or a similar A/C condo long-term for about Bt 84,000 per year. The other Bt 530,000 or so is for you to do as you like, perhaps you might have to pay some tax or perhaps not. The Thai Tax department does not know...yet

I know this is not a tax profession site, but if on an OA retirement visa, how do taxes on my US pension work? Tips? Experience? TIA

Looks like they're still trying to figure-out foreigner taxation

Sounds like all the people who said they know... still don't know, the same as the rest of us.

After reading the Tax Treaty between the US and Thailand, it specifically states that social security income and govt pensions can only be taxed by the US unless you become a resident AND a Thai national. A tax resident who lives in Thailand greater than 180 days is not a Thai National. See Article 20 and 21.
