I have recently refinanced to a split home loan to access the equity for investment in managed funds/shares: SubLoan1: $25,000 still owing SubLoan2 (I/O): $210,000 placed in a margin loan The split loan is in my name and my wife's name. The sub loans are not linked in any way. The margin loan is in my name only. As directed by my accountant, we have a signed letter (kept with our tax files) saying that Subloan2 is to be used to invest in my name only, thus all interest claims and capital gains tax payments will be made against my income. Until recently, I thought this would be ok to do by the ATO. But after reading some posts here and this:ATO split loans, I'm not so sure. Can anyone clarify if what I am doing is ok? Great website by the way. A fantastic investment resource.
