Australian property investors need to reassess how they evaluate investment properties, loan structures and future cash flow. From the 2027–28 income year, the Australian Government’s negative gearing changes will restrict how rental losses from many established residential properties can be used.
The key change is straightforward:
- Established residential properties acquired after 7:30pm AEST on 12 May 2026 will generally have rental losses quarantined.
- Those losses can no longer reduce salary, wages or other non-property income.
- Properties held before the announcement time are grandfathered under the existing rules.
- Eligible new residential builds remain able to access negative gearing against broader taxable income.
The changes do not make property investment impossible. However, they mean your investment property Australia strategy should be based on more than the potential tax deduction.

What is negative gearing?
Negative gearing occurs when the deductible costs of an investment property are greater than the rental income it produces.
Common property expenses may include:
- Loan interest
- Property management fees
- Council rates
- Insurance
- Repairs and maintenance
- Certain eligible depreciation expenses
Under the current rules, an individual investor may generally use a net rental loss to reduce taxable income from other sources, such as salary or wages. This can reduce tax payable in the year the loss occurs.
However, negative gearing does not mean an investor is making a profit. A tax deduction only reduces part of the cost of an investment loss. You still need to fund the property’s cash-flow shortfall, loan repayments and unexpected expenses.
What are the Australian Government negative gearing changes?
From 1 July 2027, rental losses from affected established residential properties will be quarantined.
“Quarantined” means the loss is recorded and carried forward, but it cannot immediately be used against non-property income. Instead, it may generally be used against:
- Rental income from other residential properties
- Future residential property income
- Capital gains from residential property, subject to the relevant tax rules
The change applies primarily to established residential properties acquired after the announcement cut-off.
The rules at a glance
| Property position | Treatment from 2027–28 |
|---|---|
| Residential property held before 7:30pm AEST on 12 May 2026 | Grandfathered under the existing negative gearing rules |
| Established residential property acquired after the cut-off | Rental losses are quarantined |
| Eligible new residential build acquired after the cut-off | Full negative gearing remains available |
| Commercial property and other asset classes | Generally outside these specific residential property changes |
The Government’s official Negative Gearing and Capital Gains Tax Reform explainer provides further detail.
Existing properties are grandfathered
If you held an eligible residential investment property before 7:30pm AEST on 12 May 2026, it is generally grandfathered.
This means rental losses from that property can continue to be deducted against other taxable income, including salary and wages, until the property is sold. The grandfathering provisions also recognise certain contracts entered into before the announcement time, even if settlement occurred later.
As a result, investors should carefully confirm:
- When the contract was signed
- When the property was acquired for tax purposes
- Whether the property was held at the announcement cut-off
- Whether a change in ownership, subdivision or restructuring affects its status
Keep contracts, settlement documents and ownership records. If you are uncertain about your position, ask your accountant or tax adviser to review the documentation.
What happens if you buy an established property after 12 May 2026?
Established properties acquired after the announcement cut-off receive transitional treatment.
Until 30 June 2027, the existing rules may continue to apply. From 1 July 2027, however, losses from those properties will generally be quarantined.
For example, suppose an established property produces a net rental loss of $12,000 in a financial year. Under the new rules, that loss could not simply be used to reduce the investor’s salary income. Instead, it would be carried forward for use against eligible residential property income or a future residential property capital gain.
This may affect your annual tax refund or tax liability, but it does not remove the underlying property expenses. Loan interest, maintenance and other costs still need to be paid.
The practical impact may include:
- A smaller immediate tax benefit
- Greater pressure on monthly cash flow
- More importance placed on rental yield
- Greater need for cash reserves
- A longer wait before some deductions can be used
- More detailed record-keeping across a property portfolio
In reality, investors should assess whether a property remains affordable without relying on an immediate tax offset.
Why eligible new builds may become more attractive
Eligible new residential builds remain able to access full negative gearing under the announced reforms. This means rental losses from a qualifying new build may continue to offset other taxable income, including salary and wages.
The policy intention is to direct investment towards properties that genuinely add to Australia’s housing supply.
Examples of eligible new builds may include:
- A newly constructed apartment bought off the plan
- A dwelling built on previously vacant land
- A duplex created through a knock-down rebuild that increases the number of dwellings
- A newly built property occupied for less than 12 months before being sold for the first time
However, not every property marketed as “new” will qualify.
Examples that may not meet the definition include:
- An established home that has simply been extended
- A freestanding replacement dwelling that does not increase supply
- A granny flat added beside an existing property
- A newly built property that was occupied for more than 12 months before being sold to another investor
Always verify the property’s eligibility with your tax adviser and obtain appropriate documentation from the builder, developer or vendor.
Established property versus new build: which strategy is better?
There is no universally correct answer. The right strategy depends on your objectives, available deposit, borrowing capacity, preferred location and tolerance for risk.
Established property considerations
Established properties may offer:
- A clearer rental history
- Greater certainty about the surrounding neighbourhood
- More predictable construction quality
- Immediate access to established amenities
- Potentially stronger tenant demand in proven locations
The trade-off is that post-cut-off established properties may have quarantined rental losses from 2027–28. You may therefore need to place more emphasis on rental income and long-term capital growth rather than the short-term tax outcome.
New build considerations
New builds may offer:
- Continued access to broader negative gearing benefits if eligible
- Modern fixtures and lower initial maintenance requirements
- Potential depreciation benefits, subject to professional advice
- Access to construction finance or staged progress payments
- A contribution to additional housing supply
There are also risks to consider:
- Construction delays
- Builder or developer risk
- Valuation changes before settlement
- Defects and warranty issues
- Body corporate expenses
- Rent assumptions that do not match the local market
- The property’s location being less established
The key is to assess the complete investment case. A tax advantage cannot compensate for an unsuitable location, excessive debt or unrealistic rental projections.
How a mortgage broker can help structure your investment loan
A mortgage broker Australia investors can trust should look beyond the headline interest rate. Loan structure, lender policy and cash-flow management can materially affect the flexibility of your investment strategy.
A broker may help you consider:
1. Borrowing capacity under different scenarios
Lenders assess rental income, existing debts, living expenses and interest-rate buffers differently. A broker can compare how lenders may treat:
- Existing investment income
- Interest-only repayments
- Proposed rent
- Construction loans
- Negative gearing benefits
- Multiple properties
- Personal and company income
This can help you understand the difference between the amount you may be approved to borrow and the amount you can comfortably afford.
2. Established property and new-build scenarios
Before making an offer, you can model the potential cash flow of:
- An established property with quarantined losses
- An eligible new build retaining broader negative gearing
- A property with interest-only repayments
- A property with principal-and-interest repayments
- A portfolio with positive and negative rental income
This comparison may make the policy implications easier to understand.
3. Loan features and account separation
Depending on your circumstances, a broker may discuss options such as:
- Variable, fixed or split-rate loans
- Offset accounts
- Redraw facilities
- Interest-only periods
- Separate loan splits for different purposes
- Equity release for a future deposit
- Construction loan progress payments
Loan purpose and account separation are important. Your broker can help you understand the finance structure, while your tax adviser should confirm the tax treatment.
4. Cash-flow and risk planning
A sound investment loan strategy should allow for:
- Vacancy periods
- Interest-rate changes
- Repairs and maintenance
- Insurance increases
- Council and body corporate costs
- Construction variations
- Delayed rental income

A practical checklist for investors
Before buying or refinancing an investment property, consider the following:
-
Confirm the acquisition date
Determine whether the property is grandfathered, transitional or affected by the new rules. -
Classify the property correctly
Establish whether it is an established property or an eligible new residential build. -
Model cash flow without the immediate tax benefit
This provides a more conservative view of affordability. -
Review your loan structure
Consider repayment type, loan splits, offsets and future equity needs. -
Allow for a financial buffer
Do not rely on perfect occupancy or unchanged interest rates. -
Obtain tax advice
Confirm deductions, quarantined losses, ownership structures and capital gains tax implications. -
Compare the whole investment case
Location, rental demand, property quality and long-term objectives remain central.
Plan your next move with greater confidence
The 2027–28 negative gearing reforms change the way many investors will assess established residential property. Nevertheless, grandfathered properties and eligible new builds retain important advantages, while established properties may still suit investors seeking strong locations, reliable rental demand and long-term growth.
The most effective approach is to understand the policy, test several scenarios and structure your finance around your broader goals: not tax deductions alone.
