Australia's 2026 Federal Budget: What the Property Tax Reforms Mean for You

Treasurer Jim Chalmers handed down his fifth federalbudget on 12 May 2026, describing it as the most ambitious in over 25 years. Atits heart is a sweeping overhaul of property taxation — one the government sayswill give younger Australians a more level playing field in the housing market.The budget introduces significant changes to negative gearing and capital gainstax (CGT), but with carefully designed grace periods that protect existinginvestors and give those in the middle of transactions time to adjust.

Negative Gearing: New Builds Only

The most significant change for investors is the restriction of negative gearing. From 1 July 2027, negative gearing for residential property will be limited to new builds only, removing the tax advantage for investors purchasing established homes. Properties already owned— or under contract — before 7:30pm AEST on 12 May 2026 (budget night) are fully exempt, so existing investors are not affected. Investors in affordable housing programs are also exempt.

What this means in practice: investors who buy established housing after budget night will still be able to deduct losses against residential property income and carry forward unused losses to future years, but will not be able to deduct them against other income like wages.

Capital Gains Tax Overhaul

The long-standing 50% capital gains tax (CGT) discount is also on the way out. From 1 July 2027, it will be replaced with inflation-adjusted indexation, aimed at ensuring tax is paid on real capital gains rather than nominal price growth. The government will also introduce anew minimum 30% tax on capital gains. Importantly, the existing 50% CGT discount will continue to apply to gains arising before 1 July 2027, and the changes will not impact the exemptions for main residences or superannuation tax arrangements.

Understanding the Grace Periods: What Applies to You

The budget's transitional arrangements are more nuanced than much of the initial coverage suggested. The key dates are budget night (12 May 2026) and the commencement of the new rules (1 July 2027) — not the end of the financial year, which has no specific significance under these reforms.

The table below sets out how the three groups of investors are treated:

One important point of clarity: the budget papers explicitly state that properties under contract (exchanged but not yet settled) before 7:30pm AEST on 12 May 2026 are included in the grandfathered group. Settlement date is irrelevant for this purpose. If you exchanged contracts before budget night, you are fully protected regardless of when settlement occurs.

The one remaining area of ambiguity concerns the grace period. The budget papers do not specify whether purchased in the grace period is determined by exchange date or settlement date. That question will be resolved when the draft legislation is released — likely within weeks.

What This Means for the Property Market

The government's stated goal is to cool investor demand for established homes while redirecting investment into new housing supply. Treasury modelling for this budget projects house prices growing approximately 2% more slowly as a result of the changes. The government says the changes will help 75,000 more first home buyers into the market over the next decade.

The rental market impact is a separate question. Limiting negative gearing to new builds directs investor activity toward outer growth corridors, apartment precincts, and masterplanned communities — areas that contribute to overall supply but do not necessarily address demand in established suburbs near employment centres, hospitals, universities, and public transport.

Record Housing Investment

The reforms are paired with a significant boost to supply-side investment. The 2026 federal budget commits to lifting total federal investment in housing to a record $47 billion, with an additional $2 billion to be spent on essential infrastructure such as roads, power, and drainage to unlock new housing developments. Labor has also committed $10 billion to build up to 100,000 homes sold exclusively to first home buyers, with construction on the first projects expected to begin in 2026–27.

The Bottom Line

These are the most significant changes to property taxation in a generation. If you own investment property, or had exchanged contracts before budget night, your position is protected for now. If you are currently in the grace period — having exchanged after budget night — you can still negatively gear until 1 July 2027, but your tax position from that point forward is materially worse than under the old rules.

If you are planning to buy an investment property or structure your finances through a trust, the landscape has fundamentally shifted. We strongly recommend speaking with your financial adviser or accountant before making any decisions — and watching closely for the draft legislation, which will resolve the remaining ambiguities around exchange versus settlement dates.
