What Is the Capital Gains Tax Discount?
The Capital Gains Tax (CGT) discount is one of the most significant tax concessions available to Australian investors. It allows eligible taxpayers to reduce the taxable portion of a capital gain from the sale of an asset, potentially halving the amount that is included in their assessable income. Understanding how the discount works, who qualifies, and how to apply it correctly is essential for anyone who holds investment property, shares, or other CGT assets.
At Trinity Accounting Practice, we help individuals, trusts, and self-managed super funds across Sydney and Australia navigate the CGT rules and develop tax-effective strategies for asset disposal.
Who Is Eligible for the CGT Discount?
The CGT discount is available to three categories of taxpayers, each receiving a different discount rate.
Individuals (including sole traders) are entitled to a 50% discount, meaning only half of the net capital gain is included in their assessable income and taxed at their marginal tax rate.
Complying superannuation funds (including self-managed super funds) are entitled to a 33.33% discount, meaning two-thirds of the net capital gain is included in the fund's assessable income and taxed at the concessional super rate of 15%.
Trusts are entitled to a 50% discount, which is generally applied before the net capital gain is distributed to beneficiaries. The way the discount interacts with trust distributions requires careful planning, and the ATO has specific rules (including Section 115-215 of the ITAA 1997) governing how trustees and beneficiaries apply the discount.
Companies are not eligible for the CGT discount. A company that makes a capital gain includes the full amount in its assessable income and pays tax at the company rate (currently 25% for base rate entities with aggregated turnover under $50 million, or 30% for other companies).
Qualifying for the CGT Discount
To qualify for the discount, three conditions must be met.
First, the asset must have been owned for at least 12 months before the CGT event occurs. The 12-month period is calculated from the date of acquisition (usually the contract date, not the settlement date) to the date of the CGT event (usually the contract date for the sale). If the asset is held for 11 months and 29 days, no discount is available.
Second, the taxpayer must be an Australian resident for tax purposes at the time of the CGT event, or the gain must relate to taxable Australian property (such as real property situated in Australia).
Third, the asset must be subject to CGT rules. Some assets are exempt from CGT, including your main residence (subject to the main residence exemption), personal use assets acquired for $10,000 or less, and motor vehicles.
How to Calculate the CGT Discount
The CGT discount is applied after any capital losses have been offset against the capital gain. The correct order of calculation is important and is often applied incorrectly by taxpayers.
The steps are as follows. First, calculate the capital gain by subtracting the cost base from the capital proceeds. The cost base includes the original purchase price plus incidental costs such as stamp duty, legal fees, and any capital improvements made during ownership.
Second, offset any current-year or carried-forward capital losses against the gross capital gain. Capital losses must be applied before the discount, not after.
Third, apply the CGT discount to the remaining net capital gain. For an individual, this means multiplying the net gain by 50%. For a super fund, multiply by 66.67% (the taxable portion after the 33.33% discount).
For example, suppose you purchase an investment property for $500,000 (including stamp duty, legal fees, and other cost base elements) and sell it three years later for $700,000. The gross capital gain is $200,000. If you have $20,000 in capital losses from other investments, the net gain is $180,000. Applying the 50% individual discount reduces the taxable amount to $90,000, which is then added to your other assessable income and taxed at your marginal rate.
Foreign Residents and the CGT Discount
Since 8 May 2012, foreign residents and temporary residents are no longer entitled to the CGT discount on capital gains that accrue after that date. If you were an Australian resident when you acquired the asset but became a foreign resident before selling, the discount is apportioned based on the number of days you were an Australian resident during the ownership period relative to the total ownership period.
For assets acquired before 8 May 2012, transitional rules may apply that preserve some or all of the discount for the period before that date. These calculations can be complex, and professional advice is essential to ensure the correct amount is claimed.
If you are an Australian resident who owns property jointly with a foreign resident spouse, each co-owner's eligibility for the discount is assessed independently based on their own residency status.
CGT Discount and the Main Residence Exemption
Your main residence is generally exempt from CGT entirely, meaning the discount is not relevant. However, the discount becomes important when a partial main residence exemption applies. This occurs when you use your home as a rental property for part of the ownership period, or when you are absent from the property for more than six years without another main residence.
In these situations, a proportion of the capital gain is assessable, and the 50% CGT discount can then be applied to the assessable portion. Careful record-keeping of the dates your property was your main residence versus income-producing is essential for calculating the correct exemption percentage.

Strategies to Minimise CGT
There are several legitimate strategies that can help reduce or defer a capital gains tax liability. Holding assets for at least 12 months ensures eligibility for the discount. Timing the sale of an asset to fall in a financial year where your other income is lower can reduce the marginal rate applied to the gain. Offsetting gains with capital losses from other investments — including shares, managed funds, or other property — reduces the net gain before the discount is applied.
For business owners, the small business CGT concessions can provide additional relief beyond the general discount. These include the 15-year exemption, the 50% active asset reduction, the retirement exemption (up to $500,000 lifetime limit), and the rollover relief. To access these concessions, the business must meet either the $2 million aggregated turnover test or the $6 million maximum net asset value test. Our business advisory team can assess your eligibility and model the most tax-effective disposal strategy.
For investors holding assets through an SMSF, the combination of the 33.33% discount and the 15% tax rate on accumulation phase income means the effective tax rate on a discounted capital gain in super can be as low as 10%, making superannuation one of the most tax-effective structures for long-term investment.
