Budget 2026 didn't abolish negative gearing. It quarantined it — for a specific category of property, from a specific date. If you understand exactly where the line sits, you can make decisions that put you on the right side of it.

Here is precisely what changed, who is affected, who is protected, and what to do about it.

What Negative Gearing Actually Is

When an investment property costs more to hold each year than it earns in rent, it's negatively geared. That annual loss — interest, expenses, depreciation minus rental income — has historically been deductible against your wages and salary, reducing your income tax.

For a high-income investor on a 47% marginal rate with a $25,000 annual property loss, that deduction was worth $11,750 per year. It was a genuine subsidy from the tax system to property investors — and a significant one.

Budget 2026 removed that subsidy for a defined category of investor.

What Changed on 12 May 2026

From 1 July 2027, negative gearing losses on established residential property purchased after 12 May 2026 can no longer be deducted against wages or salary.

The losses don't disappear — they carry forward. But they can only be:

In practical terms: the cash tax saving you used to get each year on a negatively geared property is gone. You carry the full cashflow cost until sale.

The Three Categories

Category 1: Grandfathered — Fully Protected

Any property you purchased before Budget night (12 May 2026).

Your negative gearing deductions continue permanently and without change. Nothing about the 2026 Budget affects your existing investments. You can continue to deduct losses against wages exactly as before, indefinitely.

If you have a portfolio of established properties bought before May 2026, your situation is unchanged.

Category 2: New Builds — Fully Retained

New residential construction, purchased at any time (before or after the Budget).

Full negative gearing against wages and salary is maintained. The policy was designed to encourage new housing supply, so new builds were entirely carved out. This includes off-the-plan purchases, house-and-land packages, and newly completed dwellings.

Category 3: Established — Restricted

Established residential property (not new construction) purchased after 12 May 2026.

From 1 July 2027, losses from these properties cannot be deducted against wages. Losses carry forward.

The Cashflow Reality for Restricted Properties

For a typical negatively geared established investment property:

| Scenario | Pre-Budget (or grandfathered) | Post-July 2027 (restricted) | |---|---|---| | Weekly rent | $650 | $650 | | Weekly interest + expenses | $980 | $980 | | Pre-tax loss/wk | −$330 | −$330 | | Tax saving (37% MTR) | +$122 | $0 | | Net weekly cashflow | −$208 | −$330 |

The $122/wk difference is the tax saving that disappears. On an annual basis, that's $6,344 per year in additional out-of-pocket cost for this investor — for as long as the property remains negatively geared.

This isn't a trivial amount. On a $750,000 property, it represents a meaningful reduction in effective yield.

What Happens to the Carried-Forward Losses?

Losses that can't be claimed immediately aren't lost permanently. They accumulate and sit on account against the property.

When you sell, these accumulated losses reduce your capital gain, which in turn reduces the CGT you pay.

So the tax benefit is deferred, not eliminated. But deferral matters: money now is worth more than money in 10 years. The present-value cost of deferring $6,000/yr for 10 years is significant.

What Didn't Change

It's worth being explicit about what the 2026 Budget did not do:

What Investors Should Do Now

1. Assess your current portfolio If all your properties were purchased before 12 May 2026, you're fully protected. No immediate action required. Reassess when you next buy.

2. For your next purchase, run the structure numbers An established property in an SMSF is exempt from the restriction. A new build in personal name retains full negative gearing. Before choosing, model both options against your specific numbers.

3. Don't assume negative gearing made the property a good investment The most common mistake: investors who relied on the tax subsidy to make cashflow work will find it no longer does. If a property only stacks up with negative gearing against wages, it needs to be reassessed on a post-Budget basis.

4. Consider holding period The longer you hold, the more the carried-forward losses accumulate and eventually reduce your CGT. For very long hold periods, the present-value cost of deferral decreases. Short-term investors feel the pain most acutely.

5. Model the Budget 2026 impact with PropTime's calculators PropTime's Cashflow Calculator shows you both the current rules figure and the post-July 2027 figure for your specific property. The Structure Optimiser compares personal name, company, trust, and SMSF to find which gives the best outcome under the new rules.

The Bigger Picture

Budget 2026 didn't kill property investment. It changed its tax treatment for a specific category of new purchases — established residential property — while leaving everything else intact.

The investors most affected are high-income earners buying established investment property with a plan to negatively gear it against wages. For them, the subsidy is gone.

The investors unaffected: existing portfolio owners (grandfathered), new build buyers (exempt), SMSF investors (exempt), and positively geared investors (there was never a benefit to begin with).

Understanding exactly where you sit in this map is the first step to making good decisions under the new rules.
