Labor's Capital Gains Tax Plan: What the Senate Inquiry Means for Property Investors

A Senate inquiry into Labor's proposed capital gains tax changes kicked off this week, with economists offering cautious but notable support for the government's plans — describing them as flawed yet still an improvement on the current system. For property investors across Australia, that kind of qualified endorsement from economists is worth paying attention to.

What Is Labor Proposing?

Labor's capital gains tax proposal is now under formal Senate scrutiny, with the inquiry hearing opening on 15 June 2026. The specifics of the changes are being examined by a Senate committee, and economists who appeared on the first day broadly agreed that while the plan is imperfect, it moves in the right direction compared to the existing framework.

Australia's current CGT system — which includes a 50% discount on capital gains for assets held longer than 12 months — has long been a flashpoint in debates about housing affordability and investment incentives. Any changes to that discount directly affect how property investors calculate their after-tax returns.

Why Economists Are Offering Qualified Support

The fact that economists are backing the proposal — even with reservations — signals that there is growing professional consensus that the status quo needs reform. The phrase "better than what we have" is significant language in policy circles. It suggests the existing CGT framework has real structural problems that a broad range of experts want addressed.

For property investors, this matters because it shifts the political and intellectual centre of gravity. When economists publicly support change at a Senate inquiry, it gives legislators cover to move forward with reform, even if the final legislation looks different from what was originally proposed.

What Could Change for Property Investors?

Any adjustment to the CGT discount would change the effective tax rate on investment property profits. Under the current rules, individuals who sell an investment property held for more than 12 months pay tax on only half of their capital gain — taxed at their marginal income tax rate.

If the discount is reduced or restructured, investors would pay more tax on the same gain. That could affect:

• Decisions about when to sell — investors may choose to hold or offload properties before any changes take effect
• Yield calculations — higher effective CGT changes the net return profile for new and existing investors
• Property demand — if after-tax returns fall, some investors may exit the market or reduce their portfolios
• Pricing in investment-heavy suburbs — areas popular with landlords could see shifts in supply and competition

The Senate Inquiry Process — What Happens Next?

A Senate inquiry is not legislation. It is a formal process where the committee hears evidence, receives submissions, and eventually publishes a report with recommendations. The government is not bound by those recommendations, but inquiries do shape final policy.

Day one of this inquiry featured economist testimony. Further hearings are likely, and the committee will examine submissions from a wide range of stakeholders including real estate bodies, tax professionals, and community groups. The final report could take weeks or months to land.

Property investors would be well-advised to watch the inquiry closely rather than make major decisions based on the proposal alone — the final shape of any legislation could differ significantly from what is currently on the table.

What This Means for You

If you own an investment property or are planning to buy one, now is the time to have a conversation with your accountant or financial adviser about how potential CGT changes could affect your strategy. Review your existing portfolio's holding periods and gain positions. Think about whether your current plan accounts for a scenario where the discount changes.

The Senate inquiry gives you a window of time to plan. Use it. Reforms of this nature rarely happen overnight, but the direction of travel is now clearer — and the economists advising government seem to agree that change is coming.
