Capital Gains Tax (CGT) is one of those taxes that many Australians only think about after they’ve sold an investment — often when their accountant delivers the bad news. The good thing is that CGT isn’t complicated once you understand the basics, and with a little planning, it can often be managed sensibly.
At its core, CGT is the tax you pay on the profit made when you sell an asset. That asset could be shares, an investment property, managed funds, cryptocurrency, or even certain collectables. If you sell something for more than you paid for it, the difference is called a capital gain. If you sell it for less, that’s a capital loss.
CGT isn’t a separate tax with its own rate. Instead, your capital gain is generally added to your taxable income and taxed at your marginal tax rate. This means the higher your income, the more tax you’re likely to pay on the gain.
One of the most important features of CGT in Australia is the 50% CGT discount. If you’ve owned an asset for more than 12 months, only half of the capital gain is included in your taxable income (for individuals and trusts). For example, if you made a $20,000 gain on shares you held for several years, only $10,000 is added to your taxable income. This discount is one of the key reasons why long-term investing is so tax-effective.
Capital losses are also important. If you sell an asset at a loss, that loss can be used to offset capital gains, reducing the tax you pay. If your losses are greater than your gains in a given year, the unused losses can be carried forward and used in future years. However, capital losses generally can’t be used to reduce your regular income, such as salary or wages.
Not all assets are subject to CGT. Your main residence is usually exempt, which is a significant benefit for homeowners. However, this exemption doesn’t always apply if the property was rented out, used for business purposes, or was never your primary home. This is where things can get tricky, and professional advice becomes important.
Timing also matters. Because CGT is triggered when you sell an asset, the financial year in which the sale occurs determines when the tax is payable. Some investors choose to delay selling until a new financial year or until their income is lower, such as after retirement, to reduce the tax impact.
The key takeaway is that CGT is not something to fear, but it should be considered before making investment decisions, not after. Understanding how long you’ve held an asset, whether you have losses to offset gains, and how CGT fits into your overall tax position can make a meaningful difference.
If you’re unsure how CGT applies to your investments, or you’re planning a major sale, speaking with your accountant or adviser at the SWU Group before pulling the trigger can help avoid surprises — and potentially save you a lot of tax.
