Negative Gearing Changes Explained: What the Federal Budget Means for Property Investors

Editor’s Note (May 2026): This article is based on the Federal Budget 2026-27 announcement and currently available information. We will continue updating this article as draft legislation and explanatory materials are released.

Following the Federal Budget 2026-27 announcement on negative gearing changes, many Australian property investors are trying to understand exactly how the proposed rules will work.

One of the biggest questions is whether losses will be quarantined to individual properties or whether investors can continue offsetting profits and losses across their property portfolio.

The answer could have a significant impact on future tax outcomes.

Ever since the Government announced proposed negative gearing changes, property investors have been asking the same question:

“Hang on… are losses quarantined to each individual property, or can they still be offset across my portfolio?”

It’s a pretty important detail.

Because the answer could be the difference between a minor inconvenience and a completely different investment landscape.

What Has Actually Been Proposed?

Under the Federal Budget 2026-27 proposal, negative gearing would generally be limited to new residential builds purchased from 1 July 2027, while existing investment properties held before Budget night would be grandfathered.

The proposed negative gearing changes are designed to encourage investment in new housing supply, although the detailed legislation has not yet been released.

While the headline announcement has received significant attention, the detailed legislation is still being drafted and many technical questions remain unanswered.

Can You Still Offset Property Losses Across Your Portfolio?

The Good News (Sort Of)

Based on the information released so far, the proposed changes do not appear to quarantine losses on a property-by-property basis.

Instead, the current understanding is that losses from affected residential properties would be quarantined within a residential property pool.

In plain English:

If one property loses money and another property makes money, the loss can still offset the profit.

Under the proposed rules, the $20,000 loss would likely offset the $20,000 profit from the other properties.

Net result?

Zero taxable rental income.

So far, so good.

What Changes?

The major change is that losses from affected established residential properties would no longer be used to reduce:

• Salary and wages
• Business income
• Interest income
• Other non-property income

Instead, those losses would generally be restricted to:

• Residential rental income
• Future residential property capital gains

In other words, the Government appears to be saying:

“We’re still happy for property losses to offset property profits… we just don’t want them offsetting everything else.”

The Scenario Nobody Wants

Now imagine a different version.

Let’s say losses were quarantined per property.

Using the same example:

Under a strict property-by-property system:

• You would pay tax on the $20,000 profit from Properties B and C.
• The $20,000 loss from Property A would be trapped.
• You couldn’t use it until that specific property became profitable or was sold.

That would be a dramatically harsher outcome.

Fortunately, that’s not what the Government appears to be proposing.

At least not yet.

The Problem? Nobody Knows For Certain

And this is where things get interesting.

The Budget announcement provides the broad policy direction, but the actual legislation is where the detail lives.

Questions still remain around:

• Trust ownership structures
• Mixed-use properties
• Former principal residences
• Carried forward losses
• How future capital gains will interact with quarantined losses
• Ownership percentages and joint ownership arrangements

As always, the devil isn’t in the headline.

It’s buried somewhere around page 437 of the explanatory memorandum.

What Does This Mean For Investors?

For investors with multiple properties, the impact may be significantly less severe than many headlines suggest.

If the current interpretation proves correct, portfolios with a mix of positively and negatively geared properties may still be able to offset losses against profits within the portfolio.

The biggest impact falls on investors who currently rely on rental losses to reduce PAYG income each year.

Those annual tax refunds could look very different in the future.

As more detail emerges around the proposed negative gearing reforms, investors will need to closely monitor how the legislation is drafted and ultimately implemented.

The TaxTank Take

The biggest lesson isn’t really about negative gearing.

It’s about visibility.

Every time tax rules change, investors who only look at their numbers once a year are left scrambling to understand the impact.

The investors who know their rental position, deductions, depreciation, capital growth and tax outcome throughout the year are the ones who can adapt quickly when Governments inevitably decide to “simplify” things again.

Because if there’s one thing we can guarantee, it’s that tax legislation changes far more often than property investors would like.

And occasionally, the explanation is longer than the legislation itself.

We’ll keep monitoring the proposed legislation as it’s released and provide updates as the details become clearer.

Until then, don’t believe every headline you read.

Especially the ones written before anyone has actually read the legislation.

Key Takeaways

• Existing investment properties are expected to be grandfathered.
• Negative gearing would generally be limited to new residential builds from 1 July 2027.
• Property losses appear likely to be offset against other residential property income within a portfolio.
• Losses may no longer be available to offset salary and wage income.
• The final outcome depends on legislation that is yet to be released.
