How the Federal Budget Could Reshape Property Investing for Existing and Future Investors
For years, Australian property investing has been built on a familiar formula: negative gearing on the way in and a capital gains tax discount on the way out. The 2026–27 Federal Budget proposal puts both pillars under pressure — and that could change how investors buy, hold and sell property for years to come.
While the proposals are not yet law, they send a clear signal: existing investors may keep important tax advantages, but future buyers — especially those targeting established properties — may face a very different investment equation.
The Big Budget Changes at a Glance
· From 1 July 2027, negative gearing for residential property investments is proposed to be limited to new builds.
· Existing properties held before 7:30 pm AEST on 12 May 2026 are proposed to be grandfathered for negative gearing purposes.
· For established dwellings purchased after Budget night, rental losses would generally no longer be deductible against wages and other non-property income from 1 July 2027; instead, unused losses could be carried forward or offset against residential property income.
· From 1 July 2027, the 50% capital gains tax discount is proposed to be replaced with an inflation-based cost base indexation method, together with a minimum 30% tax on capital gains.
· Investors in new builds are proposed to be able to choose between the current 50% CGT discount and the new CGT method.
· From 1 July 2028, discretionary trusts are proposed to face a 30% minimum tax, which may affect some property holding structures.
What It Means for Existing Property Investors
For existing investors, the biggest takeaway is simple: negative gearing stays.
If you held a residential investment property before 7:30 pm AEST on 12 May 2026, the proposal is that your current negative gearing treatment would remain in place. In practical terms, that means you could continue offsetting eligible rental losses against salary or other assessable income under the current rules, even after 1 July 2027.
Capital gains tax is where things become more complex. The proposed CGT reform would only apply to gains arising after 1 July 2027, so existing investors are not completely untouched. A future capital gain may need to be split across two periods, with growth before that date treated under the old framework and later growth potentially taxed under the new indexed method and 30% minimum tax rules. That makes valuations, record-keeping and sale timing far more important than many investors may be used to.
For many current landlords, this Budget proposal is not an immediate trigger to sell. In fact, investors who already own well-located established properties may find their position becomes relatively more valuable, because grandfathering could leave them with a more favourable tax treatment than someone buying the same type of asset after the cut-off date.
What It Means for Future Property Investors
Future investors are looking at a more selective and less generous tax landscape. Under the proposal, operating losses on established dwellings would effectively be ring-fenced from 1 July 2027, meaning they could no longer be used to reduce tax on wages or business income. That weakens one of the most common reasons investors have historically accepted weaker cash flow in the early years of ownership.
New builds, by contrast, appears to be a relative winner. Investors who purchase eligible new dwellings are proposed to retain full negative gearing and gain flexibility on exit, because they may be able to choose between the current 50% CGT discount and the new indexed CGT method. For higher-income investors, that could create a much wider after-tax return gap between new and established property.
In practical terms, future investors may need to rely less on tax settings and more on investment fundamentals: rental yield, holding costs, location quality and supply-demand dynamics. Established properties may still stack up where they offer strong land value, renovation upside or genuine scarcity, but the tax-driven case for buying them as a negatively geared investment is proposed to become much less attractive.
What qualifies as a New Build
Properties that meet the proposed definition of a new build include:
· Newly constructed apartments bought off-the -plan
· A duplex built through a knock-down rebuild replacing a single house
· Any residential construction on vacant land
· A newly built property occupied less than 12 months before the first sale.
Why the Capital Gains Tax Change Matters
The proposed CGT change may prove just as significant as the negative gearing reform. Under the current system, individual investors who hold an asset for more than 12 months can generally access a 50% discount on the capital gain. The Budget proposes replacing that with indexation for inflation and imposing a minimum 30% tax on gains from 1 July 2027. The policy logic is that tax should apply to real gains, not inflationary gains, but for many investors the outcome may still be a higher tax bill than under the current discount model.
This matters because residential property in Australia has often been built around a two-part tax story: ongoing deductions through negative gearing and concessional tax on eventual sale through the CGT discount. If both settings are tightened for established property, investment decisions are likely to change. Investors may hold assets for longer, favour new developments, or become more focused on entities and structures that offer different tax outcomes.
Ownership Structure Will Matter
The Budget also proposes a 30% minimum tax on discretionary trusts from 1 July 2028, with rollover relief available from 1 July 2027 for some restructures. This is highly relevant for investors who hold property through family trusts. Traditionally, discretionary trusts have offered flexibility in distributing income and managing family wealth, but the proposed changes could reduce that flexibility and increase the effective tax cost of holding investments in that structure.
That does not mean every investor should rush to restructure. But it does mean that ownership choice is becoming a more strategic decision. Investors considering future acquisitions may increasingly compare personal ownership, company structures, trusts, and superannuation-based strategies, with a stronger focus on long-term tax efficiency, asset protection, financing flexibility, and estate planning.
Why Borrowing Power Could Be Affected
With the proposed changes to negative gearing, there should be no change to the borrowing capacity for:
· Existing investors that are grandfathered under the old rules
· Investors buying new builds
· Investors with positively geared portfolios
The pressure point is for investors buying established properties after Budget night. From 1 July 2027, they are proposed to lose the ability to offset rental losses against salary and other income. Because lenders often add back the expected tax benefit from negative gearing when assessing serviceability, that tax benefit may effectively disappear under the new arrangement. If that happens, assessable income falls and borrowing capacity shrinks. While the legislation has not yet passed, lenders are already reviewing their servicing models, and early estimates suggest borrowing power could fall by around 10% to 20% in some cases.
How This Could Play Out in Practice
Existing investor: An investor who bought an established rental property before budget night would keep current negative gearing benefits. However, if the property is sold after 1 July 2027, the CGT calculation may become more complex and may produce a less favourable outcome than under today’s full 50% discount model.
Future investor buying an established dwelling: An investor who buys an older property after Budget night may still claim deductions, but from 1 July 2027 any net rental loss would generally be quarantined from salary income and carried forward or offset against residential property income instead.
Future investor buying a new build: An investor who buys an eligible new dwelling after Budget night is proposed to retain full negative gearing and may have a choice of CGT method on sale, making the after-tax profile materially stronger than for an established property.
Conclusion
For existing property investors, the Federal Budget proposal is more about protection than disruption. Grandfathering could preserve the current tax treatment of properties already held, which may leave many current owners in a comparatively stronger position.
For future investors, however, the message is much sharper: what you buy, how you hold it and how you model after-tax returns may matter more than ever. If these measures become law, the advantage may shift away from established properties and towards investments that add new housing supply. That makes this Budget less than a tax update and more of a potential reset in Australian property strategy. Because the measures are still proposed and subject to legislation, investors should use them as a planning signal — and seek tailored tax and financial advice before making major decisions.
