G'day milesy. You may not recall but there were a few posts a while ago on setting up superfunds. I posted that my superfund was registered for GST and that this enabled me to claim back the GST payed out on brokerage fees. There were a few subsequent posts, yours included, saying that this was not legal.
Shock Horror!!!!..... After a few sleepless nights I contacted my accountant who said he thought it was OK but that he would contact the tax office. Their comment apparently was "why shouldn't it be?"
I gather you are an accountant yourself, so I respect your views on this but someone has definitely got the wrong end of the pineapple...???
