Within the same financial year, say you open up a US Brokerage account to trade US shares for your Self Managed Super Fund. You put in $10k and the exchange rate is AUD$1 = USD$1. You buy shares in one company on the 1st Jan for $10k and sell it for $9.5k in June making a $500 loss (5% loss). Then you decide to withdraw all your funds back to AUD but now the exchange rate is in your favour eg. AUD$1 = USD$0.75 How would you work out the tax? You've made loss on the share trade but you've made a profit overall for the currency conversions. Which dates would you use & where do you get the exchange rates?
