CGT and Negative Gearing Changes: What Property Investors Need to Know Before the 2026 Budget

The Short Version

The federal government is looking at changing two of the biggest tax benefits property investors rely on: the capital gains tax (CGT) discount and negative gearing. Nothing has been locked in yet, but the May 2026 Federal Budget is when we'll likely find out what's happening.

If you own investment property or you're thinking about buying, here's what's actually being proposed, what it means for you, and what smart investors are doing right now.

What's Being Proposed

There are a few different ideas floating around parliament. The one getting the most attention comes from Independent MP Allegra Spender, backed by a Senate committee report. Here's what's on the table:

CGT discount cut from 50% to 30%. Right now, if you hold an investment property for more than 12 months and sell it at a profit, you only pay tax on half the gain. The proposal would change that to 70% of the gain being taxable instead of 50%. That's a meaningful difference on a big sale.

Ring-fencing negative gearing. Currently, if your investment property costs you more than it earns (mortgage interest, rates, insurance, repairs), you can offset that loss against your salary income and pay less tax overall. The proposal would stop that. You'd only be able to offset investment losses against other investment income, not your wages.

Minimum investment tax of 27.5%. This one targets trusts and income splitting. It would set a floor tax rate on investment income, including property, to stop high earners from using structures to pay less tax than they should.

Is This Actually Going to Happen?

Honestly, nobody knows for sure. The Senate committee that looked into this was split. Most members supported reform. The Coalition said the real problem is housing supply, not tax settings, and pushed back hard.

The Parliamentary Budget Office estimates the current CGT discount costs the government around $247 billion in lost revenue over the next decade. That's a big number, and it's one reason this isn't going away quietly.

The May 2026 Federal Budget is the date to watch. That's when we'll know if these are real changes or just political noise.

What About Properties You Already Own?

This is the question every investor is asking. The answer depends on something called "grandfathering", which just means whether the old rules keep applying to properties you already own.

Under Spender's proposal, any gains your property has made up to the date the new rules kick in would still get the full 50% discount. Only future gains from that point forward would be taxed at the new rate.

But that's just one version. Some politicians have argued against grandfathering entirely. If that happens, the new rules would apply to all investment properties regardless of when you bought them.

Until we see the final detail, nobody can tell you exactly how your existing properties will be treated. But planning ahead is better than scrambling after the fact.

What This Means in Real Numbers

Let's say you bought an investment property for $500,000 and sell it five years later for $700,000. That's a $200,000 capital gain.

Under current rules: You get a 50% discount. So you pay tax on $100,000. If your marginal tax rate is 37%, that's $37,000 in tax.

Under the proposed 30% discount: You pay tax on $140,000 instead. At 37%, that's $51,800 in tax.

That's an extra $14,800 in tax on the same sale. Not the end of the world, but it adds up, especially if you're building a portfolio and selling multiple properties over time.

What About Negative Gearing?

If ring-fencing goes ahead, it changes the maths on holding negatively geared properties. Right now, a lot of investors accept short-term losses because the tax deduction against their salary softens the blow. Take that away and you're wearing the full cost of the loss each year.

For investors who rely on negative gearing to make the numbers work, this could be the bigger hit. A property that was "affordable" with the tax offset might not be without it.

That said, not every investment strategy depends on negative gearing. If your property is positively geared (earning more than it costs) or if you're building equity through development rather than waiting for capital growth, these changes matter a lot less.

Why the Smart Money Isn't Panicking

Here's the thing. Every time tax changes get floated, the headlines scream "investor exodus" and "property crash." It happened in 2019, it's happening again now. And every time, the investors who do well are the ones who focus on fundamentals instead of fear.

Property investment has never been just about tax breaks. Yes, the CGT discount and negative gearing make it more attractive. But the core reason property works as an investment is because you're buying a real asset in a country with strong population growth, limited housing supply, and increasing demand.

Tax settings change. Governments come and go. But people always need somewhere to live.

What Smart Investors Are Doing Right Now

Instead of freezing up or panic-selling, here's what we're seeing the sharpest investors do:

Focusing on cash flow, not tax deductions. If your investment strategy only works because of negative gearing, it was always fragile. The best investments work on their own numbers. Positive cash flow means you're not exposed if the tax rules shift.

Building equity through development, not just waiting. This is the big one. If you buy a property on a large block, subdivide it, and build a new home on the new lot, you create equity through the development itself. You're not sitting around hoping the market goes up 5% a year so you can eventually sell and use the CGT discount. You're creating two separately titled properties from one purchase, and the value you build comes from the work you put in, not the tax system.

Looking at the whole portfolio. If you already own a property on a decent sized block, you might not need to buy anything new to grow. Subdivide what you've got, build on the new lot, and you've created a second asset without a second deposit, stamp duty, or auction. The tax treatment of that development income is different from a straight capital gain, and often more favourable.

Getting advice before the budget, not after. If you're planning to sell a property in the next 12 months, it's worth talking to your accountant now about timing. If grandfathering doesn't apply to existing properties, selling before the changes take effect could save you real money. But don't rush a sale based on rumours. Get proper advice first.

The Bottom Line

Yes, changes are probably coming. No, it's not the end of property investment in Australia.

The investors who get hurt are the ones who built their whole strategy around tax benefits. The investors who do well are the ones who buy good assets, create value through development, and focus on cash flow.

If your strategy depends entirely on the CGT discount and negative gearing to make the numbers work, now is the time to rethink it, regardless of what the government does.

And if you're sitting on property with untapped potential, a big block that could be subdivided, or an underperforming rental that could become two properties with the right development approach, that opportunity doesn't change based on what happens in the budget.

That's the kind of strategy that works in any tax environment.
