More than 1.12 million Australian property investors recorded a net rental loss in 2022–23, according to ATO data — that’s nearly half of all investors. The tax deduction that offset those losses is about to be severely restricted for established properties, and the 50% capital gains tax discount you may have been counting on is being replaced with inflation indexation from 1 July 2027. For an investor selling a property with a $400,000 gain, the difference between the current rules and the new system could be tens of thousands of dollars in extra tax. The decisions you make between now and the grandfathering cut-off on 12 May 2026 — and the 1 July 2027 implementation date — will determine which tax rules apply to your exit.

The 2026–27 Federal Budget didn’t just flag these changes — it set a hard grandfathering cut-off of 7:30 pm AEST on 12 May 2026 for negative gearing on existing properties. Properties bought after that time fall under the new restrictions from day one. For investors who bought years ago and are thinking about selling, the choice between the current 50% CGT discount and the new indexation-plus-30%-minimum system could change the net proceeds by five figures on a typical portfolio property. Understanding how rental markets respond to policy shifts helps frame why timing matters so much right now. Here’s what you actually need to know.
The single most important concept to grasp right now is grandfathering. It means existing tax treatment is preserved for assets already held before a rule change takes effect. In this case, properties purchased before 7:30 pm AEST on 12 May 2026 keep their full negative gearing deductibility indefinitely — until you sell. Properties bought after that time lose the ability to offset rental losses against salary or business income, unless they are new builds. That distinction changes the economics of every property in your portfolio.
What I tend to notice is that investors often assume grandfathering is automatic and permanent for everything. It is — but only for the properties you already own. The moment you buy another established property after the cut-off, that new purchase sits under entirely different rules, even if the rest of your portfolio is protected. That’s the kind of split treatment that catches people off guard when they expand a portfolio late in 2026.
Capital Gains Tax Scenarios: Current Rules Versus Indexation
The headline change is straightforward: the 50% CGT discount on assets held longer than 12 months disappears on 1 July 2027. In its place comes cost base indexation using CPI, plus a 30% minimum tax rate on net capital gains. But the real-world impact depends entirely on how long you’ve held the property and what your marginal tax rate is. A property bought in 2002 for $300,000 and now worth $1.3 million carries a $1 million gain. Under the current 50% discount, you pay tax on $500,000. Under the new indexation system, that gain is adjusted for inflation — but the tax rate on the adjusted gain could be higher depending on your bracket and the holding period.

| Scenario | Taxable portion of gain | Tax on $400K gain (45% rate) | Extra tax vs current |
|---|---|---|---|
| Current 50% discount | 50% of gain | $90,000 | — |
| Indexation + 30% minimum (new) | CPI-adjusted gain | Varies by holding period | Depends on CPI |
| 33% discount (previously proposed) | 67% of gain | $120,600 | +$30,600 |
| Discount removed entirely | 100% of gain | $180,000 | +$90,000 |
The table shows the 33% discount and full removal scenarios for comparison — those were proposals that were debated but not enacted. The actual new system (indexation + 30% minimum) falls somewhere between the current 50% discount and the 33% proposal, depending on inflation. For a long-held asset, the indexation adjustment can be significant, but the 30% minimum tax floor means no investor pays less than 30% on net capital gains from 1 July 2027. Income support recipients are exempt from that floor.
For investors in the top tax bracket (47% including Medicare Levy), every dollar of rental loss currently generates 47 cents in tax savings. Under the new rules for established properties acquired after the cut-off, that loss can only offset future rental income or capital gains from the same property — not your salary. The practical implications for landlord-tenant tax planning are worth reviewing with a professional who understands the transitional arrangements.
Where Property Investors Get the Exit Strategy Wrong
Assuming all properties are grandfathered the same way
Grandfathering protects the properties you already own — but only those purchased before 7:30 pm AEST on 12 May 2026. If you bought a property in 2020 and another in July 2026, the first is fully protected and the second is not. The split treatment creates a two-tier portfolio where the same investor has different deduction rules for different assets. What tends to happen is that investors treat their entire portfolio as one unit and miss the fact that their newest acquisition needs separate modelling. The fix: list every property with its purchase date and confirm which side of the cut-off each one falls on.
Ignoring the discretionary trust changes
From July 2028, discretionary trusts face a minimum 30% tax on distributions. A trust with $60,000 in taxable profit distributed to a single beneficiary currently generates roughly $8,788 in tax; under the new rules, the trustee pays $18,000 — more than double — before the beneficiary receives anything. Australia has more than 800,000 discretionary trusts, and a significant proportion are held by property investors. The three-year CGT rollover relief starting 1 July 2027 allows restructuring out of a trust without triggering a tax bill, but that window closes in 2030. If you hold property through a discretionary trust, the exit strategy needs to account for both the property sale and the trust restructuring.
Selling without modelling both CGT systems
For a property sold after 1 July 2027, gains are apportioned: the gain accrued before 1 July 2027 is taxed under the current 50% discount rules, and the gain after that date is taxed under the new indexation system. That means selling before 1 July 2027 locks in the 50% discount on the entire gain. Selling after that date splits the calculation. A formal valuation as at 1 July 2027 is required to apportion the gain, unless you use an ATO-approved alternative method. Investors who skip this valuation step end up arguing with the ATO about the split — a position that’s hard to win without documentation. My first move would be to get that valuation date on the calendar now, even if a sale is years away.
Overlooking the new build advantage
New builds retain full negative gearing against all income after 1 July 2027, plus a choice between the 50% CGT discount or indexation at sale. This is a material advantage that changes the investment case for new construction versus established properties. Investors who sell an established property and reinvest in a new build can preserve the tax benefits they’re losing on the old property. The research suggests that getting clear financial modelling on the swap is worth the cost of professional advice — the difference in after-tax outcome can be substantial.
How to Structure a Tax-Efficient Rental Exit Before the Rules Change
Audit every property against the grandfathering cut-off
Start with a spreadsheet. List each property, its purchase date, the purchase price, estimated current market value, and the type of ownership structure (individual, trust, company, SMSF). Properties purchased before 7:30 pm AEST on 12 May 2026 are fully grandfathered for negative gearing. Those purchased after that time — even by one minute — are restricted unless they are new builds. This audit tells you which properties can be sold under the current CGT discount and which ones trigger the new rules. For SMSF-held properties, the changes do not apply — the effective rate on long-held assets remains 10% — so those can be treated separately.
Model the CGT outcome under both systems before you decide to sell
For any property you’re considering selling, run the numbers under the current 50% discount and under the new indexation-plus-30%-minimum system. The difference is most pronounced on long-held assets with large unrealised gains. A property bought for $300,000 in 2002 and now worth $1.3 million carries a $1 million gain. Under the current rules at the top rate, that’s roughly $235,000 in tax. Under the new system, the CPI-adjusted gain might be $600,000–$700,000 depending on inflation, with a 30% minimum floor — resulting in $180,000–$210,000 in tax. The difference is real but smaller than the full-discount-removal scenario, because indexation softens the blow for long holders. The optimal sale date depends on your marginal rate, the holding period, and the CPI figures for the relevant quarters.
Restructure trust-held properties before 2030
If you hold property through a discretionary trust, the 30% minimum tax on distributions from July 2028 changes the economics of that structure. The government has provided three years of CGT rollover relief from 1 July 2027 to support restructuring out of a discretionary trust without triggering a tax bill. That means you can transfer the property to a different ownership structure — individual, company, or SMSF — and defer the CGT event. The window is tight: the rollover relief runs from 1 July 2027 to 30 June 2030. Planning needs to start now, because the restructuring itself may take months to execute, especially if multiple beneficiaries are involved.
Consider the timing of sale against the 1 July 2027 boundary
Selling before 1 July 2027 locks in the 50% CGT discount on the entire gain. Selling after that date splits the gain into pre- and post-1 July 2027 portions, with the pre-portion taxed under the old rules and the post-portion under the new indexation system. For a property that has already accrued most of its gain before 2027, there is relatively little advantage to waiting. For a property still appreciating, selling later means more of the gain is taxed under the new, potentially less favourable system. The PBO modelling suggests removing both concessions would reduce the overall rate of return on investment property by 15–30%, so the decision is not marginal — it changes the investment outcome by thousands of dollars per property.

Why the 12 May 2026 Cut-Off Changes the Timeline
The single most consequential date on the calendar is not 1 July 2027 — it’s 7:30 pm AEST on 12 May 2026. That is the moment the tax treatment of any new established property purchase is permanently locked in. For existing investors, the window to sell under the current 50% CGT discount runs until 30 June 2027. For anyone considering expanding a portfolio, every week after 12 May 2026 narrows the options for established properties. The trusts change in July 2028 adds another layer for investors using discretionary structures. What makes this period different from previous tax reforms is the combination of three moving parts — negative gearing, CGT, and trust taxation — all shifting at different dates. The investors who come out ahead will be the ones who map each property against each deadline, not the ones who treat it as a single problem to solve later.
