Important: The 2026 Federal Budget measures discussed in this article are proposed, not yet legislated. As of May 2026, the Prime Minister has indicated the changes will be progressed through Parliament. Seek tailored advice before making investment or structural decisions.
The negative gearing changes announced in the 2026 Federal Budget do not affect all property investors equally. Four distinct investor situations exist under the proposed rules. Each produces a different outcome. The situation that applies to you depends entirely on what you held on 12 May 2026 and what you purchase next. Understanding which situation applies is the most important step before making any property decision before July 2027.
What the 2026 Negative Gearing Changes Propose, and When They Start
From 1 July 2027, negative gearing for established residential properties purchased after 7:30 pm AEST on 12 May 2026 will be restricted. Rental losses from those properties can no longer offset salary, wages, or other non-property income. Losses will be quarantined, carried forward to offset future residential rental income or capital gains only.
Two categories are explicitly excluded from the changes: widely held trusts and superannuation funds, including SMSFs. Commercial property, shares, and all non-residential asset classes remain fully unaffected.
The four investor situations below each carry a different outcome.
Situation 1: You Held the Property Before 12 May 2026
Properties held at 7:30 pm AEST on 12 May 2026 are fully grandfathered. This includes properties where a contract had been signed, but settlement had not yet occurred at that time.
Grandfathering means the current negative gearing rules continue to apply for as long as you hold the property. Rental losses continue to offset salary and all other income. Nothing changes while the property is held. Grandfathering ends when the property is sold, and the next buyer does not inherit the status.
One planning angle has received limited coverage. An owner-occupier who purchased their home before budget night, moves out, and begins renting it out, retains full grandfathered negative gearing eligibility. The AFR described this as a carve-out allowing millions of Australians to continue negative gearing their homes. The condition is ownership before the cut-off, not the property’s use as an investment at that date.
For grandfathered investors, no restructuring is required before July 2027.
Situation 2: You Buy an Established Residential Property After Budget Night
Properties purchased between 12 May 2026 and 30 June 2027 can still be negatively geared during that transition window. From 1 July 2027, the quarantine rules apply. Rental losses can only offset income from other residential properties or the eventual capital gain at sale. Excess losses carry forward indefinitely; they are not lost, they are deferred.
The annual financial impact depends on income level. Treasury’s own data shows that on a $1 million property with a $14,810 annual rental loss:
An investor earning $80,000: deduction currently worth $4,761 per year in tax savings
An investor earning $210,000: deduction currently worth $6,961 per year in tax savings
Under quarantine, neither investor receives that annual cash saving. The higher the income, the more value is deferred each year.
A second impact applies to borrowing capacity. Many lenders currently factor expected negative gearing tax savings into serviceability calculations. When that annual saving is no longer immediately realised, the effective income position changes. Investors planning to use rental losses as part of their borrowing calculation should model their position under the new settings before committing.
Situation 3: You Buy a New Build
New residential builds are fully exempt. An investor purchasing an eligible new build can still offset rental losses against salary and other income. The CGT discount choice is also preserved; new build investors can elect between the 50% discount and the new indexation model at sale.
The definition of a new build matters. The property must genuinely add to the housing supply:
Eligible: Off-the-plan apartment, duplex replacing a single house, construction on vacant land, newly built property occupied under 12 months before first sale.
Not eligible: Single house replacing a single house, granny flat added to an existing property, renovation that does not increase the number of dwellings, new build occupied for over 12 months before sold to an investor.
The knock-down rebuild distinction is the most commonly misunderstood point. Replacing one house with another house does not qualify. Replacing one house with two or more dwellings does.
Tax benefits alone should not drive a new build decision. Construction costs remain elevated. New properties on outer suburban fringes often carry limited capital growth potential. The negative gearing exemption improves annual cash flow; it does not change the investment’s commercial fundamentals.
Situation 4: Your Property Is Commercial
Commercial property is entirely outside the proposed negative gearing changes. Office, retail, industrial, and mixed-use properties retain full negative gearing under existing rules. Rental losses continue to offset salary and other income regardless of purchase date.
This matters significantly for middle-market business owners who hold or plan to hold commercial premises alongside residential investments. The AFR reported a projected shift toward commercial real estate following the budget announcement. For business owners with retained profits in a company structure, commercial property acquisition retains the full deductibility advantage that established residential property loses after July 2027.
One important clarification: the CGT changes do apply to commercial property from 1 July 2027. The 50% discount is replaced by indexation and a 30% minimum tax on gains accruing after that date. Negative gearing is preserved, but the exit calculation changes.
The Quarantined Loss Is Not Gone
The most persistent misconception in current coverage is that the negative gearing deduction is lost for restricted properties. It is not. It is timed differently.
Treasury’s own modelling confirms this. Yoonseo purchases an established property for $519,000 after budget night, rents it out, and sells it ten years later for $814,447. She accumulates $22,879 in carry-forward losses, applies them against positive rental income in later years, and uses the remainder at sale to reduce her capital gain. Over the entire ten-year investment, she pays $186 more in total nominal tax compared to the old settings.
The deduction is deferred. For a long-term investor, the quarantine is a timing difference, not a permanent tax cost.
Four Situations, One Deadline
The negative gearing changes do not operate as a single rule. They produce four separate outcomes depending on what you hold and what you buy next.
Existing grandfathered investors face no immediate change. Investors considering established residential purchases after budget night should model carry-forward scenarios before proceeding. Investors evaluating new builds must assess the commercial case independently of the tax position. Business owners with commercial assets face no negative gearing disruption at all.

Frequently Asked Questions
Is negative gearing being abolished for all properties?
No. Existing properties held before 12 May 2026 are fully grandfathered. New builds are exempt. Commercial property and shares are completely unaffected. The restriction applies only to established residential properties purchased after budget night.
I own my home. If I move out and rent it, can I still negative gear it?
Yes, if the home was purchased before 7:30 pm AEST on 12 May 2026. The grandfathered status applies to the current owner, not the property type. It does not transfer to the next buyer at the sale.
What happens to carry-forward losses when I eventually sell?
Carry-forward losses from restricted established properties can be applied against the capital gain at sale. They reduce the taxable capital gain, providing a deferred tax benefit at the exit point.
What counts as a new build?
The property must add to the housing supply. A duplex replacing a single house qualifies. A single house replacing a single house does not. Off-the-plan apartments and construction on vacant land qualify. The property cannot have been occupied for more than 12 months before the first investor sale.
Does the negative gearing change affect my SMSF?
No. Superannuation funds, including self-managed super funds, are explicitly excluded from the proposed changes. Existing rules continue to apply.
