Australian Budget 2026: Capital Gains Tax and Negative Gearing Changes

The 12th of May 2026 changed the rules for every property investor in Australia. What was once a reliable tax strategy built around negative gearing and capital gains discounts now looks very different, and for many investors, the full picture is still unclear. The Australian budget delivered some of the biggest shifts to property taxation in nearly three decades. 

This blog breaks down exactly what changed, how the capital gains tax changes affect your position, and what the Australian budget 2026 means for investors holding or planning to buy residential property. At S & H Tax Accountants, we work closely with Melbourne property investors and small business owners, so we have put this together to give you clarity, not confusion.

What Has the Australian Federal Budget Actually Changed?

The Australian federal budget handed down on 12 May 2026 introduced two major reforms that directly affect property investors. These changes reshape how rental losses can be used and how capital gains will be taxed when a property is eventually sold.

Before diving into the details, here is a clear side-by-side view of what has shifted:

It is also worth noting that capital gains tax rules for superannuation funds in Australia remain unchanged. The one-third CGT discount inside super is not affected by these reforms, which makes SMSF structures worth reviewing for some investors.

How Do the Negative Gearing Changes Actually Work?

For years, negative gearing in Australia has worked as a straightforward tax strategy for residential property investors. When a rental property costs more to hold than it brings in through rent, that loss would reduce your taxable income across the board, including wages and business earnings.

The Australian budget 2026 has changed that arrangement, but not for everyone equally. Understanding exactly where the line falls is important before making any decisions about buying, selling, or holding property.

What Is Still Allowed?

• Negative gearing remains fully available for newly built residential properties.
• Losses on existing properties purchased before 7:30 pm AEST on 12 May 2026 are fully grandfathered.
• Commercial property and shares are not affected by these changes.
• Properties supporting government housing programs, including affordable housing, retain existing arrangements.

What Is No Longer Allowed?

For residential investment properties purchased after budget night, rental losses can no longer be offset against wages, business income, or other unrelated income sources. These losses are now quarantined.

This applies from the date of purchase, not from 1 July 2027. So if you bought an established residential property after budget night, the new rules already apply to you.

What Are the Capital Gains Tax Changes in Australia?

The capital gains tax changes announced in this budget affect anyone holding investment property, shares, or other assets for more than 12 months. The 50% CGT discount has been sitting in place since 1999, and for the first time in over two decades, that is changing.

The new system does not work the same way for every investor. What you owe depends on when your gains were made, what type of asset you hold, and how your investments are structured.

Here is what the new rules cover:

• The 50% flat discount ends for future gains: Gains that accrue from 1 July 2027 onwards will no longer qualify for the flat 50% reduction.
• Inflation indexation takes its place: Rather than a flat discount, your cost base gets adjusted for inflation. Tax is then calculated on the real gain only, not the full amount.
• A 30% floor on capital gains tax: Regardless of what your income looks like in the year you sell, the tax on net capital gains will not fall below 30% from 1 July 2027.
• Gains built up before the cutoff stay protected: The portion of your gain that accrued before 1 July 2027 is still assessed under the current rules, and the 50% discount applies to that part.
• Pre-1985 assets follow the old rules until cutoff: Gains on these assets that arose before 1 July 2027 remain exempt from capital gains tax Australia calculations.
• Super funds sit outside these changes: The one-third CGT discount that applies inside superannuation funds is not touched by this budget.
• New build buyers get to choose: If you purchase a new residential property, you can assess both the old and new CGT methods and apply whichever produces a lower tax bill.

These Australian budget tax changes cover individuals, trusts, and partnerships across the board. Investors running assets through a family or discretionary trust should also be aware that a 30% minimum tax on trust income arrives separately from 1 July 2028, meaning two rounds of structural review may be needed in the years ahead.

Who Is Most Affected by These Australian Budget Tax Changes?

The impact of these reforms is not the same for every investor. It depends on what you own, when you bought it, how it is structured, and what your income looks like. Some investors will feel very little change, while others will need to rethink their strategy entirely.

1. High-income earners with established investment properties

These investors are most exposed to the changes, as they lose the ability to offset rental losses against wages or business income. Combined with the new CGT minimum tax, the after-tax return on established residential property has shifted considerably for this group.

2. Investors using family or discretionary trusts

The Australian budget 2026 introduces a 30% minimum tax on discretionary trust income from 1 July 2028, which adds a new layer of planning for investors who distribute rental income or capital gains through a family trust. Existing trust structures will need to be reviewed well before that date.

3. Small business owners who also hold investment property

Many small business owners hold residential investment properties alongside their business assets, and this group is often overlooked in broader coverage of these Australian budget tax changes. The quarantining of rental losses away from business income changes how their overall tax position needs to be managed.

4. First-time or newer property investors

Anyone entering the established residential property market after budget night is now working with a different cash flow reality. The loss quarantine rules need to be factored into any new purchase decision from the outset.

5. SMSF Investors

Self-managed super funds sit outside the CGT changes and the negative gearing restrictions, so existing arrangements carry on as normal. For Australian property investors looking at this structure, it remains a solid and protected option that is worth a proper conversation with a specialist.

How Can S & H Tax Accountants Help You Navigate the Australian Budget Changes?

These reforms go beyond property. They reach into business structures, trust arrangements, and long-term financial plans that many investors have spent years building. For Australian property investors and small business owners across Melbourne, S & H Tax Accountants brings together property tax, business advisory, and SMSF accounting under one roof, so nothing gets missed.

• Property Purchase Timing Advice: Before you commit to buying an established property or a new build, we walk you through exactly how the updated negative gearing changes and CGT rules apply to your numbers, not just the general rules.
• Tax Structure Review: Family trusts and business-linked properties sit in a more complicated spot under the new rules, and we go through your current setup to flag what has shifted and where action may be needed.
• CGT Planning Before 1 July 2027: Gains that built up before the cutoff still fall under the current system, so we look at your portfolio with you to work out whether selling certain assets before that date puts you in a better position.
• SMSF and Investment Strategy Guidance: If you are thinking about whether an SMSF makes more sense for holding assets under the new rules, we look at your actual holdings, your timeframe, and your retirement plans to give you a grounded answer.

What Should Australian Property Investors Do Right Now?

The window to act under current rules is narrowing. Gains accruing before 1 July 2027 are still protected under the old CGT arrangements, and negative gearing Australia rules for established properties have already changed as of budget night. Every decision made between now and that cutoff date carries real tax consequences that will be difficult to reverse later.
