Capital gains tax (CGT) is the tax you pay on a capital gain. It is not a separate tax, just part of your income tax.
The most common way you make a capital gain - or capital loss - is by selling assets such as real estate, shares or managed fund investments. Managed funds also distribute capital gains you must report.
You make a capital gain or capital loss if a CGT event occurs, such as when you sell or otherwise dispose of a CGT asset.
The timing of a CGT event is important because it determines in which income year to report your gain or loss.
The definition of CGT events and an explanation about their timing can be found on the Australian Taxation Office (ATO) website.
