The 2026 budget changes are not really about negative gearing or capital gains tax in isolation. They are about structure. The reason your accountant, financial planner, and mortgage broker need to work together is that every decision—how you borrow, what you own, who owns it—affects your tax position. This is especially true now.
What Negative Gearing Actually Does
Negative gearing is not a tax dodge. It is a policy designed to encourage rental property supply. If a property does not generate enough rental income to cover all costs, you can offset that loss against other income.
For decades, this created an incentive: buy property, use the loss against salary, let capital growth do the work. Tax relief plus capital appreciation equals wealth building.
The 2026 changes say: existing investors, you keep this benefit. New investors buying existing properties do not. But new investors buying newly built or off-the-plan properties do.
This is where structure matters. The rules are now complex enough that property-by-property thinking does not work anymore. You need portfolio thinking.
Portfolio Thinking: How It Actually Works
Let us say you are an existing investor with one investment property that is negatively geared by A$10,000 per year. You use that loss against your salary and save tax.
Now you want to buy a second property. You have two options:
Option 1: Buy a new property and structure it to be neutrally or positively geared. Keep your original property negatively geared. Use the combined portfolio—first property loss offset against second property income. Refinance the first property to fund the second. The total portfolio is tax-efficient.
Option 2: Buy an existing property (cheaper than a new property). It cannot be negatively geared. It needs to be cash-flow positive from day one. This is harder and reduces your borrowing capacity.
The math says Option 1 is better. But only if you think of the two properties as one portfolio unit, not two separate investments.
Why Your Broker, Accountant, and Planner Need to Align
Your broker structures the debt. Your accountant structures the ownership (personal, trust, company, SMSF). Your planner integrates it into your overall financial position.
If these three are not talking, you end up with problems:
Your broker might recommend debt structure that is tax-inefficient. Your accountant might recommend an ownership structure that does not match your borrowing needs. Your planner might not see the integrated picture.
When they align, you get strategy. When they do not, you get costs.
The Refinancing Strategy
Here is a real example of why structure matters:
You own Property A, worth A$500,000, mortgaged at A$300,000, with a negative gearing of A$10,000 per year. You want to buy Property B, an existing property for A$400,000. Normally, you would need a deposit and new borrowing.
But Property A has grown. It is now worth more than the mortgage. You can refinance: borrow A$150,000 more against Property A. Use that as a deposit for Property B. Structure Property B debt to be positively geared or neutral.
Now you have:
Property A: A$450,000 debt, negatively geared, loss offsets against salary. Property B: A$250,000 debt, positively geared, some income left after costs. Combined: tax-efficient, both properties working together.
This does not happen accidentally. It happens because your broker, accountant, and planner planned it together.
The Real Advantage
Existing investors have grandfathering. That is the advantage. But the advantage only works if you use it strategically. Portfolio thinking lets you use it.
New investors do not have negative gearing on existing properties. But they can still build portfolios—they just need better structure, better planning, and better coordination between professionals.
The 2026 changes make integrated advisory not optional. They make it essential.
