What is capital gains tax and what rate of tax do you pay?

End of attention
Capital gains tax (CGT) is the tax that you pay on any capital gain you include on your annual income tax return. It is not a separate tax, merely a component of your income tax. You are taxed on your net capital gain at your marginal tax rate.
Your net capital gain is:
- your total capital gains for the year
- your total capital losses (including any net capital losses from previous years)
- any CGT discount and small business CGT concessions to which you are entitled.
You make a capital gain or capital loss if a CGT event happens. You can also make a capital gain if a managed fund or other trust distributes a capital gain to you.
For most CGT events, your capital gain is the difference between your capital proceeds and the cost base of your CGT asset – for example, if you sell an asset for more than you paid for it, the difference is your capital gain. You make a capital loss if your reduced cost base of your CGT asset is greater than the capital proceeds.
Generally, you can disregard any capital gain or capital loss you make on an asset if you acquired it before 20 September 1985 (pre-CGT). For details of some other exemptions, see Exemptions and rollovers.
There are special rules that apply when working out gains and losses from depreciating assets. A depreciating asset is a tangible asset (other than land or trading stock) that has a limited effective life and can reasonably be expected to decline in value over the time it is used. Certain intangible assets are also depreciating assets.
If a depreciating asset is used for a taxable purpose (for example, in a business) any gain you make on it is treated as ordinary income and any loss as a deduction. It is only when a depreciating asset has been used for a non-taxable purpose (for example, used privately) that you can make a capital gain or capital loss on it. For details on the CGT treatment of depreciating assets, see CGT and depreciating assets.
To work out whether you have to pay tax on your capital gains, you need to know:

- whether a CGT event has happened to you
- the time of the CGT event
- what assets are subject to CGT
- how to calculate the capital gain or capital loss (how to determine your capital proceeds, cost base and reduced cost base, how to apply capital losses and the methods available to calculate a capital gain)
- whether there is any exemption or rollover that allows you to reduce or disregard the capital gain or capital loss
- whether the CGT discount applies, and
- whether you are entitled to any of the small business CGT concessions
