I have never once suggested pension portability would be scrapped.
What I have suggested is it MAY be possible that EVERY expat, that's everyone from Paul Hogan to someone on an old age pension in Thailand, will be deemed a non resident for taxation purposes because the new laws, if passed, simply classify everyone outside of Australia for 183 as a non resident, with no grey areas to argue.
I have posted the non resident tax brackets previously, and they are very high, with the first bracket being $0 to $120,000, which would scoop up most expats. Note it's from $0. The first $18,500 is not exempt.
ANY and ALL income, including pensions, MAY be taxed at non resident rates. That's Paul Hogan's income, and that's the old age pensioner's "income" of the pension.
Discussion about means testing, pensions being exempt etc have been posted, but losing portability, completely, has never been suggested, and I doubt that would ever happen.
Currently, a lot of money is leaving Australian shores, legally, because the old criteria of resident / non resident had a lot of grey area one could manoeuvre around. The new criteria, if passed, is simple, with no grey area. In Australia 183 days, resident. Outside Australia 183 days, non resident. Why wouldn't the tax man want a piece of that action?
