Capital gains tax (CGT) reduces net proceeds by adding the profit from a property sale to the owner’s assessable income, which is then taxed at their marginal income tax rate. The final liability is influenced by the ownership duration, main residence exemptions, and the specific financial year in which the contract is signed.
For many investors in Melbourne’s eastern suburbs and the peninsulas, CGT is the final variable in determining whether to hold or divest. With Victoria carrying Australia’s heaviest property tax burden in 2026, the interaction between CGT and cumulative state taxes is now a primary driver of selling decisions.
How CGT is calculated on a property sale
CGT is not a separate tax but is integrated into the income tax system. A capital gain is added to the owner’s assessable income for the financial year and taxed at their marginal rate. Owners who have held the property for more than 12 months are generally eligible for a 50% discount on the taxable portion.
The importance of the contract date
The CGT event crystallises on the date the contract of sale is signed, not the settlement date. This distinction is critical for vendors managing their tax liability around 30 June. Selling in a low-income year, such as during retirement or maternity leave, can minimise the effective tax rate on the gain.
Impact of the 2026 Victorian tax environment
Investors are increasingly selling to crystallise COVID-era gains as net rental yields for inner-city investors have been materially compressed (Forge Property, February 2026). The cumulative effect of land tax rises, VRLT expansion, and the Short Stay Levy has pushed many negatively geared investors into unsustainable cash flow positions.
The timing risk
Price recovery is underway, but the window for optimal results is shifting as listed stock competition rises. While RBA rate cuts in 2025 improved the buyer pool, subsequent hikes in 2026 have partially reduced that demand, leaving vendors to weigh potential future growth against an increasingly onerous state tax environment.
Frequently asked questions
When is the CGT event triggered during a sale?
The CGT event occurs on the date the contract of sale is signed, not the settlement date. This means if you sign a contract on 29 June but settle in August, the gain is attributed to the financial year ending 30 June, regardless of when funds are received.
Can I avoid CGT if I rented out my home?
A partial main residence exemption applies if the property was lived in as a principal place of residence and then rented. Additionally, the 6-year rule allows owners to treat a former home as their main residence for up to six years if they do not nominate another property.
How do joint ownership and capital losses affect tax?
Splitting a gain between joint owners allows each person to report 50% of the gain at their own marginal rate, which often lowers the overall tax liability. Furthermore, any existing capital losses held on other assets can be used to offset the taxable property gain.
Why are Melbourne investors selling more in 2026?
Selling is driven by Victoria’s heavy property tax burden, including land tax rises, the congestion levy expansion, and restrictive tenancy law reforms. Many investors who purchased between 2017 and 2020 are choosing to crystallise gains now to avoid further erosion of net yields.
