Just to clarify for those that don't know ... NG is only for the ongoing costs of owning IP's ... ie, interest payments, PM fees, ongoing maintenance offset against income etc.
Any Capital Loss that occurs during the sale of an asset can only be offset against a future capital gain ... it cannot be claimed against general income ... however a capital gain is taxed in the financial year it occurs.
That's probably why shares won't ever be included in the NG calcs, as there is no negative ongoing expenses to offset against income - only dividends, capital gains and capital losses.
you claim NG on shares where the dividend is less than the holding costs. The holding costs include, taxes and buy in costs, interest on loans (where the purpose was to buy income producing shares), bank fees, accounants fees, financial adviser/broker fees etc.
What I think is interesting is where the ATO deny these costs for 'speculative stocks', ones that dont pay a dividend, but allow us to NG on 'speculative' housing, where the yield is insignificant but the chances of CG are great.
changing this rule might be a good way to inflate the mining sector (if it needs any help)
