I declare and pay CGT on all overseas investments including Australian shares in the country I am tax resident in. I have just one passport "Australia" but Ive been overseas so long Im non domiciled in Australia, not just non resident.
This is on the advice of my accountant in Australia.
One day when I return the ATO may wish to know where I have been paying CGT all these years.
In my experience though, if you have moved several times overseas the international tax rules become so murky and complex that even expert accountants do not agree on who owes what where. Thats been my experience.
