The CGT main residence exemption debate explained -what's been proposed, what's unlikely, and what it means for you
Published April 2026
Under current Australian tax law, when you sell your primary place of residence -your family home -any capital gain you make is fully exempt from Capital Gains Tax (CGT). This has been the case since CGT was introduced in Australia in 1985. It means that if you bought your home for $500,000 and sold it for $1,200,000, the $700,000 gain is tax-free.
This exemption applies regardless of how large the gain is, and regardless of your income. It is one of the most generous tax concessions in the Australian system and is widely seen as a foundational element of the "Australian dream" of home ownership.
Pressure on Australia's housing market -with median home prices in major cities pushing well beyond $1 million -has led several economists and housing policy groups to argue that the CGT exemption contributes to housing demand and price inflation.
The most commonly discussed proposals have included:
Groups that have publicly discussed reform include the Grattan Institute, the Australian Housing and Urban Research Institute (AHURI), and various academics in economics and public policy. Their arguments typically frame reform as a way to improve housing supply signals, reduce speculative demand, and make the tax system more equitable.
The family home is deeply embedded in Australian culture and policy. Roughly two-thirds of Australian households own their home (or are paying it off), and for most of them, the family home is their single largest asset. The prospect of paying CGT on the sale of their home is something that resonates emotionally even with people who may be years away from selling.
From a political standpoint, any party that seriously proposed removing the main residence exemption would face a severe backlash from the large bloc of voting homeowners. This dynamic has led both Labor and the Coalition to explicitly rule out touching the exemption on multiple occasions.
There is also an argument around fairness: many homeowners bought their properties decades ago and have seen substantial gains driven by broader market forces rather than active investment decisions. Retrospectively taxing those gains -particularly when many retirees rely on the proceeds from a home sale to fund their retirement -is a complex policy question that goes well beyond simple economics.
It's important to be clear: the debate around the main residence CGT exemption is specifically about the family home. The CGT treatment of shares, ETFs, managed funds, and investment properties is not under any active proposal to change.
Under current law, when you sell shares or other investments:
These rules remain unchanged and are not part of the housing CGT debate. For now, the 50% discount on shares and investment properties is intact.
It's worth clarifying a common point of confusion: investment properties have never been exempt from CGT. The main residence exemption only applies to the home you live in. What investment property owners do benefit from is the 50% CGT discount -if you hold the property for more than 12 months, only half of your capital gain is included in your taxable income.
There is a separate and ongoing debate about reducing or removing this 50% discount on investment assets, including rental properties and shares. Think tanks such as the Grattan Institute have argued that the CGT discount -introduced in 1999 -inflates demand for investment properties by making them tax-advantaged compared to other savings, which in turn drives up house prices and makes ownership harder for first home buyers.
Labor went to the 2019 election proposing to halve the CGT discount (from 50% to 25%) for new investments, but abandoned the policy after losing that election. Since then, no major party has put forward a formal proposal to change the CGT discount on investment assets, and as of April 2026 the 50% discount remains in place and is not part of any current legislative agenda.
In summary: the debate about the family home CGT exemption and the debate about the 50% CGT discount on investment properties are two distinct policy conversations, both politically sensitive, and neither has progressed beyond think tanks and academic discussion under the current government.
Given that no legislation has been introduced and both major parties have ruled out taxing the family home, there is no immediate action required for most homeowners. However, it's reasonable to stay informed, particularly if:
A financial adviser or tax professional can help you understand how existing CGT rules apply to your specific situation, particularly if you have a mixed-use property or are planning a significant sale.
As of April 2026, the main residence CGT exemption remains fully in place. No government has introduced legislation to change it. The discussion remains in the realm of policy papers, think tank reports, and academic debate.
The housing affordability crisis continues to drive calls for reform from researchers and some independent economists, but the political calculus makes it extremely unlikely that any major party will adopt this policy in the near term. Any future change would almost certainly involve a lengthy consultation period and grandfathering arrangements for existing homeowners.
