Capital Gains Tax on Property in Australia: What You Need to Know
Published on December 6, 2025 by Super Admin
When you sell an investment property in Australia for more than you paid for it, the profit you make is considered a capital gain, and it's subject to Capital Gains Tax (CGT). Understanding how CGT works is essential for any property investor, as it can have a significant impact on your overall return on investment.
CGT is not a separate tax; instead, the net capital gain is added to your assessable income in the financial year you sell the property, and you are taxed at your marginal income tax rate. For example, if you are on a high tax bracket, a large capital gain could push you into an even higher one for that year.
The good news is that if you hold the investment property for more than 12 months, you are generally eligible for a 50% CGT discount. This means you only need to add half of the capital gain to your taxable income. This discount is a major incentive for long-term property investment in Australia. Our first investment property guide highlights the importance of a long-term strategy.
It's also important to note that your main residence (your home) is generally exempt from CGT. However, the rules can get complicated if you have used your home to produce income, such as by renting out a room or running a business from it. Keeping good records is crucial for calculating your CGT liability correctly.
Your "cost base" is another key component in calculating CGT. The cost base includes the original purchase price of the property, plus other costs associated with acquiring, holding, and selling it. This can include stamp duty, legal fees, and the cost of major capital improvements. A higher cost base reduces your capital gain and, therefore, your tax liability. A good property consultant can advise on what to track.
Navigating CGT can be complex, and the rules are subject to change. It's always recommended to seek professional advice from a qualified accountant or financial advisor to understand your specific situation.
