The 2026 Federal Budget delivered the most significant changes to property investment taxation in over two decades. Treasurer Jim Chalmers announced measures that will reshape how Australians invest in residential property — with some investors significantly affected and others entirely protected.

Here is a precise breakdown of what changed, what didn't, and what it means for your investment strategy.

The Core Changes

Negative Gearing — Limited to New Builds from 1 July 2027

From 1 July 2027, negative gearing deductions will only be available on new residential properties. Investors who purchase established residential property after Budget night (12 May 2026) will only be able to deduct losses from rental income — not against wages or salary.

The key facts:

The policy takes effect from 1 July 2027, giving investors in new builds approximately 12 months to settle before the rules change.

CGT Discount — Replaced by 30% Flat Rate on Real Gains

The 50% Capital Gains Tax discount (available for assets held more than 12 months) is being replaced with a new system from 1 July 2027:

Whether the new system is better or worse depends on your hold period, inflation over that period, and your marginal tax rate. For long hold periods with moderate inflation (2-3%), the 30% real-gain method can actually produce a lower tax bill than the old 50% discount.

What Did NOT Change

This is as important as what did change:

What This Means for Existing Investors

If you own investment property purchased before 12 May 2026, the direct answer is: nothing changes for you in the immediate term.

Your existing loans are grandfathered under current rules. You keep full negative gearing deductibility on those properties indefinitely. The only thing you need to think about is whether any future purchases will be new builds or established.

The medium-term consideration is the CGT reform. If you plan to sell properties in the next 5-10 years, you'll want to model whether the new 30% real-gain method works better or worse for your specific situation. For most investors with long hold periods, the outcome is neutral to slightly positive.

What This Means for New Buyers

The calculus has changed materially for anyone planning to buy investment property after Budget night.

Established property now requires a fundamentally different investment framework. The deal has to work without the tax subsidy from wage deductibility. This doesn't mean established property is a bad investment — it means the underwriting needs to be tighter and the cashflow needs to work on its own merits.

New builds have become significantly more attractive on a relative basis. Full negative gearing is retained, plus the option to choose between CGT methods. For investors in higher income brackets, the tax advantage of new builds is now substantial.

Running the Numbers

To understand the real impact, you need to model your specific situation — your income, your marginal rate, the expected rental loss, and your planned hold period.

As a rough guide for an investor on $120,000 taxable income:

| Scenario | Old Annual Tax Saving | New Annual Tax Saving | Difference | |---|---|---|---| | $10,000 annual rental loss, established | $3,700 | $0 against wages | −$3,700/yr | | $10,000 annual rental loss, new build | $3,700 | $3,700 | No change | | $200k gain after 5yr hold, 3% inflation | $14,800 CGT | ~$13,200 CGT (new) | −$1,600 |

The impact on established property cashflow is meaningful — approximately $71/week in lost tax savings for a $10,000 annual loss at the 37% marginal rate. This has to be priced into any investment decision on established property from here.

The Strategic Response

If you own established investment properties bought before Budget night: Review your hold period and model whether to sell before or after 1 July 2027. Check whether your CGT position is better under the old or new system for your expected sale date.

If you're planning to buy investment property: The case for new builds has strengthened considerably. Run a side-by-side comparison of new vs established for any market you're considering. The tax difference is now significant enough to change the investment calculus.

The Bigger Picture

Budget 2026 is a supply-side policy. The stated goal is to redirect investor demand toward new construction rather than competition for existing stock. Whether it achieves this is an open question — but the tax incentives now clearly favour new builds, and that will shape where capital flows over the next decade.

For sophisticated investors, this creates two distinct opportunities: new build markets where full tax advantages are retained, and high-cashflow established markets where the numbers work even without the negative gearing subsidy.

The PropTime scoring model already captures both — vacancy rates, rental yields, and supply dynamics are all reflected in suburb scores. The Suburb Intelligence tool lets you filter and rank all 690 Australian suburbs to find the markets that match your new strategy.
