Capital gains result from selling an asset, including real estate, shares, and managed fund investments. You must declare all income from capital gains on your tax return. The difference between an asset’s cost basis (what you paid for it) and capital proceeds (what you received when you sold it) is a capital gain. Capital gains are distributed to you by a managed fund or another unit trust.
Do note that, though the ATO often refers to a ‘capital gains tax’ (CGT), there is no separate tax on capital gains. They are simply treated and taxed as part of your overall income.
