Capital gains tax
How to calculate capital gains tax (CGT) on your assets, assets that are affected, and the CGT discount.

.
What is capital gains tax?
Capital gains tax (CGT) is the tax you pay on profits from selling assets, such as property.
You report capital gains and capital losses in your income tax return and pay tax on your capital gains. Although it is referred to as 'capital gains tax,' it is part of your income tax. It is not a separate tax.
If you have a capital gain, it will increase the tax you need to pay. You may want to work out how much tax you will owe and set aside funds to cover it.
