Capital Gains Tax in Australia — 2025–26

Capital Gains Tax (CGT) in Australia is not a separate tax — it is included in your assessable income for the year you dispose of an asset. A capital gain arises when you sell an asset for more than its cost base. CGT applies to property (excluding your main residence in most cases), shares, cryptocurrency, collectibles, and most other assets acquired after 19 September 1985.

The 50% CGT Discount

One of the most significant concessions available to Australian individual taxpayers is the 50% CGT discount. If you hold an asset for more than 12 months before selling, you can reduce the capital gain by 50% before applying your marginal tax rate. The CGT 50% Discount Calculator shows the tax difference between selling before and after the 12-month threshold — often a compelling reason to hold an asset just a little longer. Companies are not eligible for the discount; superannuation funds receive a one-third discount instead.

Property and the Main Residence Exemption

Your main residence (the home you live in) is generally fully exempt from CGT. However, if you rented the property out at any point, or if it was not your main residence for the entire ownership period, a partial exemption applies. The Main Residence Exemption Calculator calculates the taxable portion of the gain based on the proportion of time the property was used as your principal place of residence. The Property CGT Calculator handles investment property where no exemption applies, factoring in the full cost base including stamp duty and capital improvements.

Shares and Crypto

Share investors need to include brokerage on both purchase and sale in the cost base — the Shares CGT Calculator does this automatically. Cryptocurrency disposals are taxable events under ATO guidance: swapping one coin for another, spending crypto, or transferring to another wallet can all trigger CGT. The Crypto CGT Calculator applies Australian CGT rules to cryptocurrency transactions. For any other asset type — from collectibles to business assets — use the General CGT Calculator.
