Can anyone clarify if this applies to those whom are declared by the ATO to be "non-residents for tax purposes" or to those whom are out-and-out non residents (i.e. a citizen from another country)?
Re the former, I obtained that status from the ATO moons ago but didn't lose my "resident" status.
As for
For all you non-resident brothers with CGT assessable assets, don't sell them til you're a resident again! Not that hard is it?
I'd get proper advice on that. When I was a "non-resident for tax purposes", the family home was subject to CGT assessment for the period that I held that status. As most would know, the family home is generally exempt from CGT. Mind you it was rented.
I'd be concerned that the same mind-set could apply and any capital gains between 8 May and when you return to Australia to become a resident again would lose the concession.
