The New Property Tax Rules Explained Through a Real Investor Scenario

What the Negative Gearing Changes Really Mean: A $1 Million Investor Scenario

There has been a lot of noise around negative gearing and capital gains tax.

But behind the politics is a very practical real estate question:

Will the numbers still work for future property investors?

That is the question buyers, sellers, developers and landlords should be asking.

The most important point is this: the changes do not wipe out existing investors. Properties already held before 7:30pm AEST on 12 May 2026 are protected from the negative gearing changes. That includes properties where a contract had already been entered into but settlement had not yet occurred. In other words, if an investor had already exchanged before budget night, the existing negative gearing treatment continues until that property is sold.

That matters.

Real estate decisions are not made overnight. Investors exchange contracts, organise finance, settle later, lease the property, manage repairs, and plan around tax settings that may affect them for years.

Changing the rules after people had already committed would have been far more damaging.

The government has avoided that.

The real impact is on future purchases, especially investors buying additional established rental properties after the reform.

What Is Actually Changing?

From 1 July 2027, negative gearing for residential property will be limited to new builds that genuinely add to housing supply. Existing investment properties held before budget night remain protected, but future purchases of established rental properties will be treated differently.

For established residential investment properties purchased from 7:30pm AEST on 12 May 2026, rental losses will no longer be deductible against wages or salary from 1 July 2027. Those losses will instead be deductible only against other residential property income, including residential property capital gains. If the investor has excess losses, they can carry those losses forward to future years.

That is the major shift.

The government is not saying, “We do not want investors.”

It is saying: if taxpayers are going to subsidise investment losses, that support should be directed toward new housing supply.

That is why new builds are treated differently.

An investor buying a genuine new dwelling can still access negative gearing. The policy is designed to push investor demand toward new housing rather than established homes that first-home buyers and owner-occupiers are also trying to buy.

What Has Negative Gearing Cost the Tax System?

This is not only a housing affordability debate.

It is also a debate about the cost of tax concessions.

Negative gearing is the part of the rental deduction system where an investor’s rental property produces a net loss, and that loss reduces other taxable income.

For years, the investment model was simple:

Buy the property.
Accept the annual rental loss.
Use the tax system to soften the cash-flow pain.
Hold for capital growth.
Sell later with a discounted capital gain.

That model has been powerful because negative gearing and capital gains tax worked together.

The government’s view is that if billions of dollars in tax benefits are going to support property investment, that support should help create new homes — not simply help investors compete for existing stock.

That is the policy message.

It does not remove every rental deduction. It does not retrospectively attack existing investors. It does not remove support for new dwellings.

It narrows the subsidy.

How Many People Are Actually Affected?

The immediate impact is narrower than many headlines suggest.

The people most affected are not existing investors who already hold property under the old rules. They are future buyers of established investment properties, especially those relying on tax refunds to carry weak cash flow.

The Budget papers say the reforms are aimed at reducing distortions that favour highly leveraged investment in existing housing. The policy is expected to shift some demand from investors to owner-occupiers and redirect tax support toward new supply.

That is important for the market because real estate prices are not only shaped by who owns property today.

They are shaped by who is willing to buy tomorrow.

The Rental Supply Question

This is the part that deserves more attention.

Australia still needs rental properties.

Every rental property must be owned by someone. It may be a private investor, a build-to-rent operator, a super fund, a community housing provider or the government. But historically, private investors have supplied a large part of Australia’s rental housing.

So the practical question is simple:

If future investors receive less tax support for buying established rental properties, will some of them step back?

Some will.

Others will shift toward new builds. Some will demand higher rental yields. Some will avoid older apartments with high strata levies, rising insurance, repairs and limited growth prospects.

That could reshape the market.

Older apartments with weak yields may become less attractive to investors.

New apartments may receive more attention because the tax treatment remains more favourable.

Some established rental properties may move from investors to owner-occupiers.

That may help first-home buyers.

But it does not automatically increase rental supply.

Rental supply increases when more dwellings are built and made available for rent. That is why the government is trying to push investor demand into new housing.

The idea is logical.

The execution is the test.

For the policy to work, developers need feasible projects. They need finance. They need pre-sales. They need construction costs to stack up. And they need investors to believe the rules will remain stable long enough to justify the risk.

Why Negative Gearing and CGT Worked Together

Negative gearing by itself is not a profit.

It means the property is losing money each year.

The attraction was that the annual loss could reduce the investor’s taxable income, while the investor waited for capital growth.

Capital gains tax was the second part of the equation.

Under the old system, many investors could sell after holding the property for more than 12 months and receive the 50 per cent CGT discount. The new rules move back toward an inflation-indexation model, with a minimum tax on real capital gains applying from 1 July 2027. The Budget papers state that the reforms will reintroduce capital gains tax cost-base indexation and introduce a 30 per cent minimum tax on capital gains.

That changes the psychology of property investment.

The old mindset was:

“I can lose money each year, receive a tax benefit along the way, then hopefully make it back through capital growth and a discounted capital gain.”

That equation is now weaker for future buyers of established properties.

A Real Example: The $1 Million Investor Test

Let’s move away from theory.

An investor buys an established apartment in NSW for $1,000,000.

But the real starting point is not $1 million.

On a $1 million NSW purchase, current transfer duty is approximately $40,432, based on Revenue NSW’s standard transfer duty scale. This excludes legal costs, loan costs and other settlement costs.

So the investor starts here:

This matters.

People often say, “If I buy for $1 million and sell for $1.2 million, I made $200,000.”

Not really.

The investor starts behind the line.

Now assume the property rents for $900 per week, or $46,800 per year.

The annual costs might look like this:

Under the old negative gearing system, that $23,200 annual loss could be deducted against the investor’s salary income.

If the investor was on a 47% marginal tax rate, the tax benefit could be about $10,904.

The investor is still losing money.

But under the old system, the tax benefit softened the loss.

That is why many investors accepted weak or negative cash flow. They were not buying the property for rent alone. They were buying for future capital growth, while the tax system helped carry the holding cost.

Under the new rules, for an established property bought after the reform applies, that immediate salary tax benefit disappears.

The investor may still have the $23,200 annual rental loss, but they cannot use it to reduce wage or salary income. The loss is carried forward and may only be useful later against residential property income or residential property capital gains.

That is a very different cash-flow position.

Before and After: Negative Gearing Cash Flow

Now Add Capital Growth

Let’s test the same property over 10 years.

Assume:

After the first three years, the property is still worth $1,000,000.

After the next seven years growing at 3 per cent per annum, the estimated value is approximately $1,229,874.

At first glance, that looks like a gain.

But once stamp duty is included, the gain is lower.

The headline gain of $229,874 becomes about $189,442 before selling costs, vacancy, extra repairs, land tax, agent’s fees, legal fees or any unexpected strata levy.

That is the real-world difference.

CGT Before the Reform: 50% Discount

Under the old system, if the investor held the property for more than 12 months, the 50 per cent CGT discount would generally apply.

Stamp duty and other acquisition costs are generally included in a CGT cost base. The ATO explains that the cost base is generally what it cost to buy the asset plus other costs incurred to hold and dispose of it; the ATO’s own CGT examples include stamp duty as part of the cost base.

Using our simple example:

Under the old system, the investor may pay around $44,519 in CGT.

But during the 10-year holding period, the investor may also have received annual negative gearing benefits.

If the annual tax benefit was about $13,837, over 10 years that could be worth about $138,370.

That is why the old model was attractive.

The investor carried annual losses, received tax relief along the way, and then paid tax on only half the capital gain.

CGT After the Reform: Inflation Indexation at 3%

Under the new system, the focus shifts to the real gain after inflation.

Using 3 per cent inflation per year for 10 years, the indexed cost base becomes approximately:

$1,398,000

Now compare that with the sale price.

In this scenario, there is no taxable real capital gain under the indexed system.

Why?

Because the property had no growth for three years, then grew at only 3 per cent per annum for the next seven years. Once stamp duty and inflation are included, the property has not produced a real capital gain.

So the CGT change is not always the biggest problem.

In a low-growth environment, indexation may reduce or even eliminate the taxable capital gain.

The bigger issue is cash flow.

Before and After: The Real Investor Result

This is the real point.

Under indexation, the investor may not pay CGT if the property only keeps pace with inflation or underperforms it.

But that does not mean the investment worked.

The investor still had to fund the annual cash loss year after year without the same negative gearing benefit.

That is why future investors will look much harder at rental yield, strata levies, insurance, repairs, interest rates, land tax and genuine capital growth prospects.

The Gut Feeling Test: Can Investors Trust the Rules?

There is another issue sitting underneath the numbers.

Confidence.

Investors make property decisions over long timeframes. They do not buy for six months. They buy, borrow, hold, lease, repair, refinance and plan around rules that may affect them for 10, 15 or 20 years.

So even if the government says existing investors are protected, and even if new builds are favoured today, investors will naturally ask:

What happens if the rules change again?

That is the gut feeling test.

The current reform is designed to push investor demand toward new housing supply.

But first-home buyers are also being encouraged into new housing through grants, concessions and government support.

That creates a new tension.

If investors and first-home buyers are both pushed toward the same new apartments and townhouses, the competition may simply move from the established market into the new-build market.

And then the political question becomes obvious:

If investor demand later helps push up the price of new homes, will a future government change the rules again?

That uncertainty matters.

A tax concession only works if investors believe it will last.

If investors think today’s new-build concession may become tomorrow’s political target, some will hesitate. Others will demand a higher return before buying. Some may avoid long-settlement off-the-plan contracts unless the numbers are very strong.

That is why confidence is just as important as the tax rate.

For new supply to be delivered, developers need pre-sales.

For pre-sales to happen, investors need confidence.

For investors to have confidence, they need stable rules.

The biggest concern is not only what the government has changed today.

It is whether investors trust that the rules will not be changed again tomorrow.

Alan’s View

This reform does not wipe out existing investors.

That needs to be said clearly.

Existing holdings are protected. Contracts entered into before budget night are protected. New builds continue to receive favourable tax treatment.

The real impact is on future investment decisions.

If an investor buys an established property after the reform applies, the property has to stand more on its own. It cannot rely as heavily on annual tax refunds to make weak cash flow feel acceptable.

And when we model a realistic scenario — 0 per cent growth for three years, then 3 per cent per annum, with stamp duty included — the numbers become much clearer.

The CGT outcome may not be the biggest issue.

The cash-flow burden is.

The investor may avoid CGT under indexation if the property barely beats inflation. But they still have to carry the annual losses without the same tax relief along the way.

That is where the market will change.

Good properties will still attract investors.

But weak-yielding, high-cost, low-growth properties will be harder to justify.

In real estate, tax rules matter.

But fundamentals matter more: rent, location, scarcity, quality, construction risk and long-term buyer demand.
