How Chalmers’ sweeping tax reforms, restricting negative gearing, overhauling capital gains, and redirecting billions, will reshape property investing, home ownership, and the nation’s fiscal future
Treasurer Jim Chalmers delivered a budget on Tuesday night that analysts are already calling the most transformative since the Hawke-Keating era, one that bets Australia’s generational housing crisis can be solved, in part, by dismantling the tax architecture that helped create it
The centrepiece: rewriting property tax rules
For decades, negative gearing and the 50% Capital Gains Tax discount have been the twin pillars of Australia’s property investment system. As of Budget night, both are being fundamentally restructured, in what the government frames as a pursuit of “intergenerational equity.”

Negative gearing: restricted to new builds
From 1 July 2027, investors who purchase established residential properties will lose the ability to offset rental losses against other income such as wages. The change applies from Budget night for new purchases, investors holding properties before 12 May 2026 are fully grandfathered. Investors in new builds retain the full deduction and can continue to offset losses against all income.
How negative gearing works, and why it matters
When a property costs more to hold than it earns in rent, the investor is “negatively geared.” Under current law, that loss reduces taxable income from all sources, including wages.
Illustrative example
Rental income $30,000
Mortgage interest (−$38,000)
Other holding costs (−$7,000)
Annual property loss (−$15,000)
Salary $120,000
Taxable income (currently) $105,000
Taxable income (after reform, established property)$120,000
After the reform, that $15,000 loss cannot reduce salary income for established-property investors, it can only be carried forward against future property income.
Capital gains tax: 50% discount replaced with inflation indexing
From 1 July 2027, the 50% CGT discount for assets held more than 12 months will be replaced by cost-base indexation, meaning investors pay tax only on the gain above inflation, not on a flat half-price basis. A 30% minimum tax on net capital gains will also apply. Investors in new residential housing may choose whichever method is more favourable to them.
Old system vs. new system, a worked example
Current 50% discount
Purchased for $500,000
Sold for $800,000
Nominal gain $300,000
50% discount (−$150,000)
Taxable gain $150,000
New inflation-indexed system
Purchased for $500,000
Inflation adj. (20%)+$100,000
Indexed cost base $600,000
Sold for $800,000
Taxable gain $200,000
In a high-growth, moderate-inflation market, most established-property investors will pay more tax under the new system. In high-inflation environments, the indexed method can occasionally be more favourable, particularly for slower-appreciating assets.
Editorial Analysis
The numbers tell a stark story. According to SuperGuide, 83% of the CGT discount’s benefit flows to the top 10% of taxpayers by income, and 83% of new investor loans in 2025 went to established properties, not new housing. Chalmers is targeting a self-reinforcing loop: wealthier investors outcompeting first-home buyers for the same finite pool of existing homes, subsidised by the tax system. The policy logic is sound. The execution risk is real, particularly if rental supply contracts before new supply comes online.
Supporters argue the reform will:
- Reduce speculative demand for existing homes
- Redirect investment toward new housing supply
- Tackle intergenerational wealth inequality
- Tax real gains, not inflationary noise
- Improve first-home buyer access at auctions
Critics warn the reform could:
- Reduce total rental stock as investors exit
- Push rents higher in the short term
- Damage investor confidence broadly
- New builds ≠ affordable housing in practice
- Be reversed by future governments
Treasury modelling cited by SBS News estimates house price growth will temper from around 6% to 4% annually for a couple of years, described by one economist as “a less bad outcome” rather than a meaningful affordability fix. Prices do not fall; they simply rise more slowly.
“It doesn’t take house prices backwards, it’s just a less bad outcome. It’s not necessarily fixing the problem.”
Personal tax relief: money in Australian pockets
The government paired its structural property reforms with meaningful personal tax relief, partly as political counterbalance, partly as genuine cost-of-living support in a period when Treasury forecasts inflation near 5% by mid-2026.
Tax relief implementation timeline
Now (2025–26)
$250 Working Australians Tax Offset, over 13 million taxpayers benefit
July 2026
Income tax rate drops 16% → 15%; $1,000 instant work-related deduction introduced, no receipts required, 6.2 million workers, average saving of $205
July 2027
Income tax rate drops 15% → 14%; negative gearing and CGT reforms take full effect for new purchases
July 2028
30% minimum tax on discretionary trusts, closing a major wealth-sheltering vehicle used by high-net-worth families
Editorial Analysis
The $1,000 instant deduction is a politically elegant move. It costs the budget far less per person than complex deduction regimes, benefits workers who previously couldn’t be bothered claiming deductions, and reduces ATO compliance costs by around $380 million annually. Per Budget.gov.au, for high-income investors, the property tax changes will likely outweigh these personal relief measures significantly in net impact, but for middle Australia earning $60,000–$120,000, the combined effect of rate cuts, the offset, and instant deduction represents a meaningful real-terms improvement in take-home pay.
Housing infrastructure and foreign investor restrictions
Beyond tax reform, the government is deploying direct spending to unlock new housing supply, acknowledging that tax changes alone cannot build the homes Australia needs.
- A $2 billion Local Infrastructure Fund to unlock up to 65,000 new homes by co-funding roads, sewers, and utilities that make development economically viable
- The ban on foreign investors purchasing established homes extended to 2029, reducing offshore demand competition
- Infrastructure funding structured to require state and local government co-investment, creating accountability for delivery
Editorial Analysis
The infrastructure fund is arguably the most direct supply-side intervention in the budget. Per API Magazine, enabling infrastructure is what makes new housing development financially viable for developers. However, 65,000 homes over an unspecified period barely registers against Australia’s cumulative housing deficit, estimated at over 200,000 dwellings. Meaningful supply response requires sustained state government cooperation on rezoning and planning approvals, which no federal budget can mandate. The gap between announcement and delivered dwellings is historically large in Australian housing policy.
What this means for new property investors
For Australians considering property investment, particularly younger first-time investors, the new environment demands a fundamental shift in approach. The era of tax-driven property investing is ending. The era of fundamentals-driven investing is beginning.
1
Cash flow is now king
With negative gearing restricted for established properties, assets that can’t approach neutral gearing become structurally harder to justify. Before purchasing, calculate rental yields, vacancy rates, strata fees, interest costs, insurance, and land tax, then stress-test at higher rates.
2
New builds get better tax treatment, but quality varies enormously
New residential builds retain access to negative gearing and the choice of CGT method. However, off-the-plan developments often carry oversupply risk, inflated developer pricing, and construction quality risks. The tax incentive is real; the investment quality must be assessed independently. Buy quality, not just “new.”
3
Location fundamentals matter more than ever
In a lower-tax-benefit environment, the underlying quality of the asset, population growth, employment hubs, infrastructure investment, transport access, school catchments, becomes the primary return driver. Chasing social-media “hot spots” is now riskier than before.
4
Don’t assume endless capital growth
Treasury’s own modelling shows growth moderating. A sound investment should survive on fundamentals, rental yield, tenant demand, asset condition, even if price growth is slower than the last two decades. “Property always doubles” is an inheritance of an unusually favourable policy era that is now changing.
5
Keep debt conservative; maintain generous buffers
With inflation near 5% and further rate movements possible, over leveraged investors face compounding pressure: higher interest costs, tighter deductions, and forced-sale risk. Conservative borrowing and meaningful cash buffers, for repairs, vacancies, rate rises, strata surprises, are not optional in this environment.
6
Ask the most important question before every purchase
“Would this still be a good investment even without the tax benefits?” If the honest answer is no, walk away. That single question filters out most decisions that will look poor in hindsight.
