Australia's federal government has unveiled sweeping changes to property tax arrangements in its 2026 budget, targeting two pillars of the country's investment-friendly housing system: negative gearing and the capital gains tax (CGT) discount. The reforms will limit negative gearing — which allows property investors to deduct rental losses from their taxable income — to new builds only, while replacing the existing CGT discount with a markdown tied to inflation. A minimum tax rate of 30% will also apply to future capital gains and to trust distributions, closing avenues that wealthier taxpayers have long used to reduce their bills. Existing investments are fully grandfathered under the negative gearing changes, but the CGT reforms will apply to all gains from 2027 onwards, meaning current investors are not entirely shielded from the new rules.

The changes come amid one of the most acute housing affordability crises in the developed world. Australian homes now cost nearly ten times the average household's annual income — quadruple the ratio of roughly 25 years ago — while rents have doubled over a similar period. The combination of negative gearing and the CGT discount, introduced around the turn of the millennium, is widely seen as a turning point that decoupled house prices from wages. Treasury data reveals the stark inequality these concessions have created: the top 1% of earners, with incomes around A$800,000 per year, have received an average benefit of more than A$700,000 since 2000, compared with just A$12,400 for a typical worker earning around A$62,000. The government argues the reforms begin to rebalance a tax system that has long favoured income from wealth over income from work.

Opponents of the changes are vocal. The Coalition opposition, led by Shadow Treasurer Tim Wilson, accuses the government of "intergenerational warfare" and warns the reforms will backfire. The government's own budget documents acknowledge that the tax changes will put upward pressure on rents and result in approximately 35,000 fewer homes being built over the next decade — figures critics say will harm the very young Australians the government claims to be helping. Investors such as retired Melbourne couple Cliff and Christine Hill, who own multiple investment properties, argue the changes will prompt landlords to raise rents or exit the market entirely, worsening supply without solving affordability.

Independent economists offer a more nuanced verdict. Treasury estimates the reforms will push property prices roughly 2% lower than they would otherwise be, as reduced investor demand creates more room for first-home buyers and owner-occupiers. The revenue impact is initially modest, but is projected to reduce the deficit by more than A$20 billion per year within a decade. However, analysts stress that tax changes alone cannot fix a housing shortage built up over decades. Australia's restrictive planning laws, slow construction approvals — build times have lengthened by around 40% in the past 15 years — and a chronic undersupply of social housing remain the structural roots of the crisis. The budget attempts to address this with a new A$2 billion Local Infrastructure Fund designed to encourage states to loosen planning restrictions, which researchers suggest could unlock more than 60,000 additional homes per year.

The political backdrop is significant. Labor proposed similar reforms at the 2016 and 2019 elections, losing both times in part due to the housing policies. But a worsening crisis, a shifting voter base of younger Australians facing bleak ownership prospects, and a strong parliamentary majority have given the government confidence to act. For the roughly 13-year-olds already running the numbers on their future housing affordability, the reforms represent a symbolic if incomplete step. As Danielle Wood, chair of the government's independent Productivity Commission think tank, puts it: the tax changes are "not a panacea on house prices" — but meaningful reform on multiple fronts, including planning and construction, may gradually shift a market that has long been defined by inequality.
