7:30pm, 12 May: The Night Australia's Property Tax Rules Changed

At 7:30pm on Tuesday 12 May 2026, Treasurer Jim Chalmers rose in Parliament to deliver the Federal Budget. From that minute, every established home bought by an Australian investor stopped attracting a tax treatment that had shaped the property market for generations. Six weeks later the changes were law. They take effect on 1 July 2027, and they are already reshaping how investors, developers and buyers behave.
This analysis argues that the reforms are best understood not as a tax on investors but as a deliberate redirection of capital toward new housing, and that redirection will only succeed if the market has the confidence, capacity and credibility to build. On each of those three counts, Brisbane in late 2026 is under strain.
The reform in numbers
- 7:30pm AEST, 12 May 2026 : the cut-off for negative gearing on established dwellings
- 25 June 2026 : the legislation passes Parliament with Greens support
- 1 July 2027 : the new rules commence
- 50% → indexation + 30% : the capital gains discount is replaced with cost-base indexation and a 30% minimum tax on gains
- ~75,000 : the government's claim of additional Australians helped into home ownership over ten years
- 4.60% : RBA cash rate, a 15-year high

### What actually changed
The Treasury Laws Amendment (Tax Reform No. 1) Bill 2026 makes two headline changes for residential property.
Negative gearing. For established residential dwellings acquired after 7:30pm AEST on 12 May 2026, net rental losses can no longer be deducted against wages or other income from 1 July 2027. Those losses can still be offset against residential rental income and carried forward. Properties held before budget night are grandfathered, and new residential dwellings are unaffected.
Capital gains tax. From 1 July 2027, the 50% CGT discount for individuals, trusts and partnerships is replaced with cost-base indexation, together with a 30% minimum tax rate on net capital gains. The change applies to gains accruing from that date; assets are deemed to be disposed of and reacquired at market value on 1 July 2027, so earlier gains are preserved under the old rules until sale. Owners of eligible new dwellings and affordable housing can choose between the existing 50% discount and the new indexation method.
A related amendment, secured by the Greens, ends the ability of self-managed super funds to take out new limited recourse loans to buy residential property. The government has also announced a separate 30% minimum tax on discretionary trust distributions from 1 July 2028, which has not yet been legislated.
The design is unambiguous: established housing loses its preferential treatment, while new housing keeps it. Overnight, new apartments became the only tax-favoured game in town.
### The case for the reform
The government's argument is that decades of tax concessions have encouraged investors to compete with first-home buyers for the existing housing stock, adding demand without adding supply. By confining the most valuable concessions to new construction, the reform aims to steer investment capital toward building.
The government says the package could help around 75,000 more Australians into home ownership over the next decade. Reported Treasury modelling points to slower house-price growth rather than an immediate fall, with rents possibly slightly higher than otherwise in the short term. Supporters also point to equity: Prime Minister Anthony Albanese framed the changes around people who have "nothing to sell but their time."
For build-to-rent operators and institutional investors, the settings are broadly favourable. Widely held trusts and superannuation funds sit outside the negative gearing change, and the overall direction rewards long-term rental supply.
### The case against
Critics come from several directions at once, which is part of what makes the reform so contested.
Industry groups warn that reduced investor demand will mean fewer homes, not more. The Property Council has been reported projecting around 35,000 fewer homes over a decade, a figure that, like the government's own estimate, is a contested projection rather than an observed outcome. The Housing Industry Association expects investor demand and near-term apartment development to soften.
Academics question the scale. Remy Davison of Monash University described the government's estimate as "a drop in the bucket" against the size of the housing shortfall, and argued that a two-tier system favouring new builds could push up land prices as developers compete for sites suitable for multi-dwelling projects. He also described the indexation approach as adding complexity that may change when owners choose to sell.
From the other side of politics, the opposition is direct. Opposition Leader Angus Taylor called the measures "toxic taxes", and the Coalition has said it wants to scrap the negative gearing limits. On 19 October, Pauline Hanson pledged that One Nation would reverse the CGT and trust changes and restore negative gearing for all investors, capped at two properties. Meanwhile the Greens, who supported the bill, argued that grandfathering existing concessions was a missed opportunity.
The reform is too much for investors, too little for its critics on the left, and politically reversible. That uncertainty is itself a cost.
### The market reaction
Investors appear to have reacted before the legislation was even passed. Rental listings fell across every capital city in May, the month of the Budget, according to Neoval data reported in October. Auction clearance rates have fallen to around 51%, the lowest reading in about five years, according to Cotality data.
Attributing these movements solely to the tax changes would be a mistake. As our analysis of Brisbane's market earlier this week showed, rising interest rates, falling consumer confidence and a sharp increase in listings were already reshaping conditions. But the direction is consistent with what the reform intends: established-stock investors are pausing, and the question is whether new-build investment will rise to replace them.
### Why the timing is brutal
The reform arrives in the most difficult macroeconomic environment for property in more than a decade.
- Interest rates are at 4.60%, a 15-year high, following the RBA's fourth increase of 2026 in late September. Westpac economists have flagged the possibility of another rise.
- Unemployment rose to 4.7% in September, a five-year high.
- Consumer sentiment fell to 80.4 in October on the Westpac–Melbourne Institute index, a reading consistent with deep household pessimism.
- Business confidence fell to 76.5 in September on Roy Morgan's measure, its sixth straight month below 80 and just above its all-time low. A record 76.3% of businesses expect "bad times" over the next five years, and only around a quarter say now is a good time to invest in growing their business.
Tax incentives work by changing the relative attractiveness of decisions people are already willing to make. When households and businesses are this cautious, even a well-targeted incentive struggles to convert into action. A buyer who is worried about their job, their mortgage repayments and the direction of prices is not easily persuaded by a better tax treatment on a new apartment.
### Brisbane: rewarding the thing that is hardest to do
Nowhere is this tension sharper than in South-East Queensland. Research by Urbis for the Property Council found that inner Brisbane is falling short of its apartment needs by roughly 4,000 to 5,000 dwellings a year, and that around 35% of projects scheduled beyond 2027 are rated moderate to high delivery risk. Apartment construction costs rose 14% in the 2025 financial year, and the existing apartment stock is often cheaper to buy than new product is to build. Competition for labour and materials is expected to intensify as Olympic infrastructure ramps up ahead of 2032.
The policy rewards precisely the thing Brisbane is struggling hardest to do: build.
If feasibility remains out of reach for many projects, the redirection of investor capital may produce higher prices for the limited new stock that does get built, rather than more homes. That outcome would reward developers who can deliver, but it would not necessarily improve affordability.
### What it means for business and consumers
For developers , the new-build advantage is real and should be communicated clearly. But the same environment that creates the advantage also erodes buyer confidence. Marketing that leans on tax benefits without addressing completion risk, builder quality and price certainty will struggle. The developers who benefit most will be those whose brands buyers already trust to deliver.
For investors , the calculus has shifted from "which property" to "which kind of property". Established-home investors face weaker after-tax returns on new purchases, while new-build investors retain the old treatment but take on construction and resale risk. Professional advice has rarely been more important.
For first-home buyers , reduced investor competition for established homes may help at the margin, but higher interest rates and borrowing constraints remain the dominant barrier.
For businesses beyond property , from agencies and trades to retailers, the reform is another signal of a market in transition. Weak consumer and business confidence will shape spending decisions well beyond housing.
### The Studio Orris perspective
Tax settings can redirect money. They cannot create confidence, builders, or buyers who feel safe to commit. The negative gearing and CGT overhaul is one of the most significant changes to Australian property in a generation, and it has a coherent logic: reward new supply rather than competition for existing homes. Whether it works will depend less on the legislation than on the conditions around it, including interest rates, construction capacity, political durability and, above all, confidence.
For the businesses we work with, the lesson is familiar. Incentives open a door; trust is what gets people to walk through it. In a market where buyers are cautious and the rules may change again after the next election, clarity, credibility and a brand people believe in are worth more than any tax line.
So we will leave you with the question we put in our video: did Canberra just fix housing, or did it simply pick a winner?

### Sources and research
Research note: the government's 75,000 figure and the Property Council's ~35,000 figure are projections, not observed outcomes. Market movements since May reflect interest rates and broader conditions as well as the tax changes. The discretionary trust measure had not been legislated at the time of writing.
