Negative Gearing and CGT Changes Explained: What Should Melbourne Property Owners Do Before July 2027?

The federal government’s negative gearing and capital gains tax reforms have now moved beyond proposal stage. The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 and Income Tax Rates Amendment (Tax Reform No. 1) Act 2026 were registered on 26 June 2026, with the core negative gearing and CGT changes scheduled to apply from 1 July 2027.

For Melbourne property owners, the key point is this: properties held before 7:30pm AEST on 12 May 2026 are generally grandfathered for negative gearing until sold, while established residential properties bought after that time will face tighter loss-deduction rules from 1 July 2027. The 50% CGT discount is also being replaced with cost base indexation and a 30% minimum tax rate on real capital gains accruing from 1 July 2027. For most owners, the practical step before July 2027 is to model the numbers carefully rather than rush to sell.

What Is Actually Changing?

Negative Gearing Changes

Negative gearing — using rental losses to reduce salary or other non-property income — will be limited for established residential investment properties. Under the Treasury summary of the 2026–27 tax changes, new builds can continue to be negatively geared before and after 1 July 2027.

For established residential property:

Properties held before 7:30pm AEST on 12 May 2026 are grandfathered and can continue to use existing negative gearing rules until sold.

Properties bought between Budget night and 30 June 2027 may be negatively geared during that period, but not from 1 July 2027.

Properties bought from 1 July 2027 will not be able to use rental losses to reduce salary or wage income.

Unused losses can still be carried forward and used against future residential property income, including relevant capital gains.

The Budget tax reform page frames the change as limiting negative gearing to new builds so tax support is directed toward additional housing supply.

CGT Changes

From 1 July 2027, the 50% CGT discount for individuals, trusts and partnerships will be replaced with cost base indexation and a 30% minimum tax rate on real capital gains. The reforms apply prospectively, so gains accruing before 1 July 2027 can still be treated under the current 50% discount rules, while gains after that date are treated under the new regime.

For assets already owned before 1 July 2027, the transitional approach effectively splits the gain. The value at 1 July 2027 becomes central to separating the old-rule gain from the new-rule gain, which is why owners considering a future sale should think seriously about valuation evidence.

New residential builds receive special treatment. Investors who buy eligible new builds can continue to negatively gear them and, when selling, can choose either the 50% CGT discount or the new indexation and minimum-tax approach.

What It Means for a Melbourne Seller

The widely shared idea that “holding one extra year per eleven offsets the extra tax” is too neat. Treasury’s own negative gearing and CGT tax explainer shows that outcomes vary with inflation, capital growth, holding period and marginal tax rate.

For example, using 2.5% inflation, a $500,000 asset held for 10 years and a 5% annual return, Treasury’s example produces a higher taxable gain under indexation than under the current 50% discount. At lower real returns, indexation may reduce tax. At higher real returns, it may increase tax. That means the right decision is property-specific, not rule-of-thumb driven.

For an investor “stuck with a dud” — for example, a flat-growth villa unit with rising maintenance costs — the tax change alone rarely justifies a fire sale. Grandfathered properties keep existing negative gearing treatment until sold, so the decision should still rest on the asset’s fundamentals: rental yield, vacancy risk, owners corporation costs, maintenance, suburb growth outlook, debt levels and alternative uses for the capital.

Market conditions matter too. AMP chief economist Shane Oliver has warned that rate hikes, lower confidence and investor tax changes are likely to weigh on prices, with AMP expecting national average property prices to fall around 5% over 2026–27. That is a forecast, not a certainty, but it reinforces the need to stress-test sale price, rent, interest rates and holding costs.

Practical Steps Before July 2027

1. Confirm Your Key Dates

Start with the contract date and settlement history. For negative gearing, the critical timing is whether the property was held, or a contract had been entered into, before 7:30pm AEST on 12 May 2026. For CGT, the critical date is 1 July 2027, because gains before and after that date are treated differently.

2. Get a Valuation Strategy

If you expect to sell after 1 July 2027, ask your accountant or tax adviser whether you should obtain a valuation around that date. The Budget materials say taxpayers may be able to use a valuation or an ATO-supported apportionment method, but the right approach will depend on the property, records and future sale timing.

3. Model Hold-Versus-Sell Scenarios

Compare at least three scenarios: selling before 1 July 2027, holding for several years, and holding long term. Include tax, selling costs, vacancy, repairs, insurance, land tax, owners corporation fees, rental growth and likely capital growth. The “best” answer may change if your property is highly leveraged, has poor rental demand or needs major works.

4. Use Registered Advice

This is not an area for guesswork. Work with a registered tax agent or adviser and check their registration through the Tax Practitioners Board public register. If financial product advice is involved, speak with an appropriately licensed financial adviser.

5. Review the Property Itself

The tax outcome is only one part of the decision. Older Melbourne apartments, villa units and houses should also be assessed for defects, future maintenance, accessibility, renovation scope and resale appeal. If long-term liveability or accessible upgrades could affect the property’s buyer pool, providers such as Mobility Access Modifications can help owners understand practical changes like ramps, grab rails and accessible bathroom modifications before committing to a hold-or-sell plan.

What This Means for You

The reforms are now law, but the main property tax changes still hinge on future start dates and transitional rules. For Melbourne property owners, that creates a planning window rather than a panic deadline.

Before July 2027, confirm your purchase timing, gather valuation evidence, model the tax impact and make the decision based on the property’s fundamentals. Some agencies, such as Forge Real Estate, offer investment property reviews, rental yield analysis, suburb-level growth data and vendor support designed to avoid forced discounting. Used alongside a registered tax professional, that kind of review can help turn the new rules into a practical hold, improve or sell decision.
