For decades, governments of both stripes promised they would never touch negative gearing. On Budget night, 12 May 2026, that promise finally cracked. The Government used the 2026-27 Federal Budget to announce the biggest shake-up of property investor tax in a generation. The negative gearing changes 2026 has thrown up will reshape how Australians buy, hold and sell investment property.
Here is the part that matters before you panic or celebrate. Most of the changes do not start until 1 July 2027, and if you already own an investment property, you are almost certainly protected. The detail is where it gets interesting, so let's walk through what was actually announced, who it touches, and what to do next.
The two reforms, at a glance
The 2026-27 Federal Budget announced two linked reforms aimed squarely at property investors. From 1 July 2027, negative gearing will be limited to new builds, and the long-standing flat 50% capital gains tax discount will be replaced with an inflation-based discount plus a minimum 30% tax on gains.
The Government's stated logic is to point tax support at new housing supply rather than bidding wars over existing homes. Whether it works is a separate question, and one the economists are already arguing about. For now, here is the shape of it.
| Measure | Now (pre-1 July 2027) | From 1 July 2027 |
|---|---|---|
| Negative gearing | Available on any rental property | Limited to new builds for new purchases |
| Losses on established property | Deductible against any income (e.g. wages) | Deductible only against residential property income, carried forward |
| CGT discount | Flat 50% for assets held 12+ months | Inflation-based discount, minimum 30% tax on the gain |
| New-build advantage | Same rules as any property | Keeps full negative gearing against any income |
| Your existing properties | Current rules | Grandfathered, current rules continue |
One important caveat up front. These are announced measures, not yet enacted law. As of mid-2026 the reforms have been outlined in the Budget and a Prime Ministerial media release, but the legislation still has to pass Parliament. The mechanics, including the exact indexation method and how carry-forward losses work, can change before they commence. Treat everything below as the announced policy, not settled fact.
The two key dates you need to know: Budget night and 1 July 2027
There are two dates doing all the heavy lifting here, and people keep confusing them.
The first is Budget night, 12 May 2026, the moment the Treasurer rose to deliver the Budget. That is the grandfathering cutoff. A contract exchanged before that night is treated differently from one signed after it.
The second is 1 July 2027. That is when the new rules actually bite for the measures that affect property. The gap between announcement and commencement is more than a year, which is deliberate. It gives investors and the market time to adjust, and it gives the Government time to legislate.
Why the announcement date matters more than the start date
This trips people up, so it is worth being blunt. Grandfathering is pegged to when you committed to buy, not when the new rules start. If you owned (or were under contract for) an established investment property before Budget night on 12 May 2026, you keep the existing negative gearing treatment indefinitely, even though the new regime begins in July 2027.
Buy an established property the day after Budget night and you are in the new camp, even though the rules do not formally start for another year. The announcement date locks you in. The start date just sets the clock running. If you are within a whisker of either date, this is exactly the kind of timing question to run past a registered tax agent before you sign anything.
Negative gearing changes 2026, explained in plain English
What is negative gearing?
Negative gearing is when the cost of owning an investment property, mostly the interest on your loan plus rates, insurance and maintenance, is higher than the rent it brings in. That shortfall is a loss. Under the current rules, you can deduct that loss against your other taxable income, including your salary, which lowers your overall tax bill.
It has been a cornerstone of Australian property investing for years. It is also one of the most contested tax settings in the country, and it sits at the centre of the long-running housing tax reform debate that finally forced the Government's hand.
Negative gearing is being limited to new builds from 1 July 2027
The headline change is simple to state. From 1 July 2027, full negative gearing will only be available on new builds.
Buy a brand-new dwelling and you can still deduct rental losses against your other income, wages included, exactly as investors do today. The Government has kept this incentive specifically to push investor money into new construction. So the tax break does not vanish, it gets redirected towards the kind of property the country is short of.
What happens if you buy an established property after Budget night
This is where it tightens. If you buy an established (existing) property after Budget night on 12 May 2026, the negative gearing rules change for you from 1 July 2027.
You can still claim your losses, but only against residential property income, not against your salary or other income. If your losses are bigger than your rental income that year, you do not lose them. You carry the unused portion forward to offset future property income. The deduction still exists, it just cannot reach into your pay packet anymore. For a high-income earner relying on negative gearing to soften the holding cost of an established rental, that is a meaningful shift in the numbers.
Capital gains tax changes: the end of the flat 50% CGT discount
What is the CGT discount?
When you sell an asset for more than you paid, the profit is a capital gain, and it gets added to your taxable income. The CGT discount is the rule that, if you have held the asset for at least 12 months, you only pay tax on half the gain. The other 50% is effectively tax-free. That discount applies to individuals, trusts and partnerships.
The new inflation-based discount and the 30% minimum tax on gains
From 1 July 2027, the flat 50% discount is being replaced. In its place comes a discount based on inflation, paired with a minimum 30% tax on the gain.
The thinking is that the old discount rewarded all gains equally, even gains that were largely just inflation rather than real profit. An inflation-based approach is meant to tax the real gain more accurately. The minimum 30% tax sets a floor, so that very high earners cannot use the discount to push their effective rate on gains too low. The exact indexation formula has not been finalised, which is one more reason to treat this as a moving target until the legislation lands.
Who and what the CGT changes apply to (property is only part of it)
Here is a detail plenty of headlines missed. The CGT changes are not limited to residential property. They apply to all CGT assets held by individuals, trusts and partnerships: shares, business assets, the lot.
The transitional rules matter. The new treatment only applies to gains arising on or after 1 July 2027. Any gain you accrued before that date keeps the current 50% discount. And assets acquired before 1985, the so-called pre-CGT assets, stay exempt as they were.
Who this hits, and who it leaves alone
Owner-occupiers and your family home: the main residence exemption is safe
If you own the home you live in and nothing else, you can largely stop reading. The main residence exemption is unaffected. Your family home is not taxed when you sell it, just as before. Income support recipients are also exempt from the minimum 30% tax.
Existing investors: how grandfathering protects you
If you already held an investment property before Budget night on 12 May 2026, your existing arrangements continue unchanged. You are grandfathered. The old negative gearing rules and the 50% CGT discount on gains up to the cutoff still apply to you. That is genuine certainty for the many Australians who already own a rental, and it is the reason the changes have not sparked a panic sell-off.
New investors after Budget night: established vs new builds
For anyone buying from here on, the property type decides your tax treatment.
- New builds: full negative gearing against any income, including your wages, exactly as investors claim it today. The most generous treatment on offer.
- Established property: losses quarantined to property income and carried forward, and the new CGT rules apply to gains from 1 July 2027.
That gap is the whole point of the policy. It is designed to steer buyers towards new stock, which connects directly to the broader push to close Australia's housing shortfall, and sits alongside other levers shaping who buys what, including shifting foreign investment trends.
What it means for the new-build market and housing supply
If the policy works as intended, expect investor demand to lean towards new and off-the-plan dwellings. A new-build investor keeps full negative gearing against their wages while every other purchase loses it. That is a deliberately sweet deal, and developers will market it hard.
There is a catch worth naming. Off-the-plan and new builds carry their own risks: construction delays, valuation shortfalls at settlement and weaker capital growth in the early years compared with established homes in blue-chip suburbs. A tax incentive does not erase those risks, it just changes the maths. If you are weighing a new build purely for the tax treatment, that is precisely the moment to get independent advice rather than a developer's spreadsheet. For investors thinking about long-term strategy, the broader principles of building wealth through property still apply, and the tax tail should not wag the investment dog.
Could this affect property prices?
This is the question everyone wants answered, and honestly, nobody knows for certain.
The grandfathering does a lot of work to soften any sudden shock. Existing investors have no reason to dump stock, because their treatment does not change, so you are unlikely to see a wave of forced selling. The more likely effect is at the margin, where new buyers weigh established homes against new builds and the after-tax numbers nudge some of them one way or the other.
Any prediction beyond that is a forecast, not a fact. Modelling the price impact depends on assumptions about interest rates, supply and how investors actually behave, and the real-world outcome could easily land somewhere else. If the changes do gently cool established-home competition, that may give owner-occupiers and first-home buyers a touch more breathing room, which has long been part of the appeal of strategies like rentvesting.
Frequently asked questions about the 2026 negative gearing and CGT changes
Do I lose negative gearing on a property I already own?
No. If you held the property before Budget night on 12 May 2026, you are grandfathered. Your existing negative gearing arrangements continue unchanged, including the ability to deduct losses against your wages.
Will my family home be taxed when I sell?
No. The main residence exemption is unaffected by these reforms. Your principal home remains exempt from capital gains tax on sale, exactly as it is today.
Should I buy before or after 1 July 2027?
It depends entirely on what you are buying and your own tax position, so there is no universal answer. Buying an established property before the new rules start does not grandfather you unless you committed before Budget night on 12 May 2026. The protection is tied to the announcement date, not the start date. If full negative gearing matters to your strategy, a new build will keep that treatment regardless of when you buy. This is exactly the kind of decision to model with a registered tax agent rather than guess at.
What property buyers should do next (and why a buyer's agent helps)
First, do not make a rushed decision on the back of a Budget announcement that is not yet law. The most important point in this entire article is that these are announced, not enacted, measures. The detail can shift before 1 July 2027, and acting on assumptions can cost you.
Second, get your timeline straight. Know whether your purchase falls before or after the Budget night cutoff, and whether the property is established or a new build, because those two facts decide your treatment.
Third, build the right team. A good buyer's agent can help you read the new-build versus established trade-off with clear eyes, source property that stacks up on fundamentals rather than tax breaks alone, and avoid the off-the-plan traps. You can connect with a buyer's agent through GoMatch to find someone who knows your target market. And because the negative gearing changes shift the holding-cost calculation on established stock, it is worth running your borrowing position past a professional too. You can talk to a mortgage broker to understand how the numbers change for your situation.
This article is general information only and is not financial, legal or tax advice. The reforms described are announced measures that are not yet law and may change, so please consult a licensed professional, such as a registered tax agent or financial adviser, before acting on anything here.
The headline is dramatic. But the timeline is generous, and existing owners are genuinely protected. Get the dates right, know your property type, and take advice before you sign. That is how you turn a confusing policy change into a clear plan.
