Frequently Asked Questions

How does the 50% CGT discount work?
If you hold an asset for more than 12 months before selling, you only pay tax on half the capital gain. For example, a $100,000 gain becomes a $50,000 taxable gain. This discount applies to individuals and trusts but not companies.
Is your home subject to capital gains tax?
Your principal place of residence (the home you live in) is generally exempt from CGT under the main residence exemption. However, if you rent it out or use it for business, partial CGT may apply for the period it was not your main residence.

What is Capital Gains Tax?

Capital Gains Tax (CGT) is the tax you pay on the profit when you sell an asset like shares, property, or cryptocurrency. Australia offers a 50% CGT discount for individuals who hold assets for more than 12 months.

How this calculator works

Enter your purchase price, sale price, and any selling costs (agent fees, legal costs). The calculator computes the capital gain, applies the 50% CGT discount if you held the asset for 12+ months, and calculates the tax at your marginal rate. If you made a loss, it shows the capital loss amount which can be used to offset future capital gains. The marginal rate selector lets you choose your tax bracket (16%, 30%, 37%, or 45%) for an accurate result.
