There is something almost ritualistic about Australia's negative gearing debate. It surfaces, it inflames, it recedes. Investors brace, first-home buyers hope, and economists argue past each other in op-ed columns until the political temperature drops and the whole thing is quietly shelved. But this time, something may be different.
Government sources have confirmed to the Sydney Morning Herald that Treasury is actively modelling changes to negative gearing that would restrict the practice to two investment properties per investor. The work is not yet policy, and no announcement is imminent. But the fact that Treasury has been tasked with producing numbers at all signals that the Albanese government is, at minimum, seriously weighing options that previous Labor administrations retreated from under electoral pressure.
Negative gearing allows property investors to deduct losses on their rental properties from their taxable income. Combined with the 50 per cent capital gains tax discount available on assets held longer than twelve months, the arrangement has become one of the structural pillars of Australian residential property investment. According to the Australian Taxation Office, well over two million Australians hold investment properties, and a significant portion of those claim net rental losses each year.
The centre-right case for preserving negative gearing is not without substance. The arrangement, its defenders argue, encourages private capital into the rental market, increasing supply and moderating rents over time. Landlords take on genuine financial risk, they say, and the tax treatment simply reflects standard deductibility principles that apply to virtually every other form of investment. Restricting access, the argument goes, would reduce rental supply precisely when Australia's housing shortage is most acute.
Those arguments deserve to be taken seriously. But they sit alongside a growing body of evidence that the current system disproportionately benefits wealthier Australians who already hold multiple properties, while doing relatively little to address the supply shortage where it matters most: affordable housing in high-demand areas. The Reserve Bank of Australia and various independent economists have noted over the years that demand-side tax incentives tend to inflate prices rather than meaningfully expand supply, since most negative gearing activity involves the purchase of existing dwellings rather than new builds.
A two-property cap, as Treasury appears to be examining, would be a deliberately moderate reform. It would leave the vast majority of investors untouched; most Australians who hold an investment property hold only one. The cap targets what some economists describe as portfolio investors, those with three, four, or more properties, who critics argue are the primary beneficiaries of a tax concession originally designed with a far more modest investor in mind.
The political history here matters. Labor took a more ambitious negative gearing reform to the 2016 and 2019 elections and lost, at least in part, on the back of a sustained campaign by property and real estate interests warning of market collapse. The Morrison government's success in weaponising that policy against Labor remains a cautionary tale inside ALP strategy circles. A cap of two properties, rather than an outright restriction, could be read as an attempt to draw a more defensible political line.
What strikes you about the current moment is how the housing affordability crisis has shifted the terms of the conversation. The Australian Bureau of Statistics has documented years of declining home ownership rates among younger Australians, and public tolerance for arrangements that appear to favour established investors over aspiring buyers has worn noticeably thin. That political shift does not automatically make a particular tax reform wise, but it does change what is electorally survivable.
The honest answer is that nobody knows with certainty what a two-property cap would do to rents, prices, or supply. Modelling helps, but the housing market is shaped by dozens of overlapping forces: zoning rules, construction costs, interest rates, migration levels, and state government planning decisions that sit largely outside federal control. Treasury's work will be important, but it will not be the last word.
If there is a lesson here, it is one that resists simple telling. Good housing policy requires holding two things at once: the legitimate interests of investors who provide rental accommodation to millions of Australians, and the equally legitimate interests of those locked out of ownership by a market that has, for two decades, moved faster than wages. A cap on negative gearing may or may not strike the right balance. That is precisely why the modelling matters, and why the debate that follows it deserves more rigour than it usually gets.
