I contact ato - they said as a citizen you never lose tax residency. He asked 2 other ppl he works with who also confirmed this. He said only way to lose it would be picking up citizenship in another country.

Hi does anyone know if the 180 days or less to avoid tax implications start from each calendar year Jan to Dec? Or is it rolling fron time of entry? For example you arrive in beginning of November get 60 days extend another 30 and your now at start of Feb. Does that mean you only have 90 days max left until November or 120/130 days from the new calendar year?

If you have a tax-free pension in your home country such as Australia will that pension be tax-free in Thailand? It is essential to know if my pension of about US $2,700 or Aus $4000 a month with tax-free super will be taxed otherwise I will spend 179 days in Thailand and the rest in Cambodia or maybe the Philippines or back in Australia. Presently it's all up in the air with no clear result. No one seems to know.
