Tax Changes Every Investor Should Know

Three tax changes worth watching closely

Tax rules rarely stand still, and increasingly, neither does the information available to the Australian Taxation Office (ATO).

From expanded data matching around rental properties and high-value lifestyle assets to significant changes to negative gearing announced in the 2026–27 Federal Budget, there is plenty for property owners, investors and business owners to keep across.

At Yield Business Advisory, our professionals believe changes like these reinforce an important point: good tax management is no longer something to think about only when it is time to lodge a return.

Here are three key tax changes and compliance areas worth having on your radar.

1. Rental Properties and Holiday Homes Are Firmly in the Spotlight

The ATO continues to use an extensive range of third-party information to check rental property income and deductions.

Its data-matching programs draw information from a range of third-party sources to help identify common problems including omitted properties and rental income, incorrect deductions and errors involving jointly owned properties.

Holiday homes also require particular care.

If you rent out a holiday home, the rental income generally needs to be declared. However, deductions are generally only available to the extent the property is rented or genuinely available for rent.

That can become complicated when a property is also used privately, reserved for family or friends, offered at below-market rates or only made available for rent during selected periods.

The ATO’s rental property guidance provides further information about declaring rental income and claiming eligible expenses.

It is exactly the type of situation where working with an accountant can help ensure income and deductions are treated correctly.

2. Lifestyle Assets Are Being Data Matched Too

It isn’t only property data attracting ATO attention.

Under its lifestyle assets data-matching program, the ATO obtains insurance information relating to certain high-value assets.

The program covers caravans and motorhomes, motor vehicles and thoroughbred horses valued at $65,000 or more; fine art valued at $100,000 or more per item; marine vessels valued at $100,000 or more; and aircraft valued at $150,000 or more.

The information can help the ATO build a broader picture of a taxpayer’s assets and accumulated wealth and identify potential issues involving income tax, capital gains tax, GST, fringe benefits tax and superannuation.

You can read more about how the ATO collects and uses this information through its lifestyle assets data-matching program.

Owning a valuable boat, vehicle, artwork or horse doesn’t automatically mean there is a tax problem. What matters is whether your financial affairs and reporting accurately reflect your circumstances.

The team at Yield Business Advisory can help clients understand where lifestyle assets may have taxation implications, particularly where an asset is owned through a business, related entity or self-managed super fund.

3. Negative Gearing Is Changing

One of the headline tax measures from the 2026–27 Federal Budget is a significant change to negative gearing for residential property.

From 1 July 2027, negative gearing will generally be limited to new residential builds. Importantly, properties already held before 7.30pm AEST on 12 May 2026 are exempt from the negative gearing changes, meaning existing investors are not automatically losing their current arrangements.

For established residential properties acquired after that Budget-night cut-off, from 1 July 2027 rental losses will generally be able to offset other residential property income, including relevant capital gains, but not unrelated income such as salary and wages. Excess losses can be carried forward for use against residential property income in future years.

New builds will continue to qualify for negative gearing, reflecting the Government’s intention to encourage investment in additional housing supply.

The Australian Government provides further information about these changes in its 2026–27 Budget tax changes.

The Budget also included significant changes to capital gains tax arrangements from 1 July 2027, adding another consideration for investors when making future decisions.

This Is Where Professional Tax Advice Counts

ATO data matching, rental deductions, private use, capital gains and changing negative gearing rules can quickly become complicated, and the correct approach will depend on individual circumstances.

Rather than trying to interpret every announcement yourself, this is where having a professional who understands both the rules and your financial position can be invaluable.

At Yield Business Advisory in Tanunda, our team can help clients understand what changes apply to them, identify potential issues early and plan ahead.

Tax rules will continue to evolve. The important thing is making sure your strategy evolves with them.
