Picture a typical Saturday morning at a property auction. In the crowd, you will likely find an aspiring first-time buyer hoping to secure a place to live, standing shoulder to shoulder with an everyday investor looking to build financial security for their retirement. Both parties are participating in a system shaped by long-standing tax policies.
Our housing market is a frequent topic of conversation across the country. Recently, the Federal Government confirmed it is examining changes to two major property tax policies ahead of the May 2026 budget: negative gearing and the Capital Gains Tax (CGT) discount.
Let’s explore what these proposed changes look like and what they could mean for everyday Australians.
Understanding the Basics
To make sense of the proposed reforms, we first need to define the terms.
- Negative Gearing: This occurs when the cost of owning an investment property (like mortgage interest, maintenance, and council rates) is higher than the rental income it generates. Under current Australian tax law, investors can deduct this financial loss from their regular wage income, which reduces their overall tax bill.
- The CGT Discount: When you sell an investment property for a profit, you pay Capital Gains Tax. However, if you have owned that property for more than 12 months, the government currently gives you a 50% discount on the tax applied to that profit.
These policies have historically made property a highly attractive investment vehicle. But as housing prices have soared, pressure has mounted to review them.
What is on the Table for 2026?
According to recent reports and statements from Treasurer Jim Chalmers, the government is modelling a few specific adjustments ahead of the May budget (The Guardian, 2026). Rather than completely scrapping these benefits, the proposed changes are more targeted:
- Capping Negative Gearing: Instead of unlimited deductions, the Treasury is looking at new rules that would limit the use of negative gearing to a maximum of two investment properties per person.
- Reducing the CGT Discount: The government is also considering winding back the CGT discount from 50% down to 33% for assets held longer than 12 months.
The Case for Reform
Supporters of the changes argue that the current tax settings heavily favour wealthy investors over first-home buyers.
Advocates for reform, including the Australian Greens, argue that the existing massive tax breaks allow cashed-up investors to outbid everyday Australians, artificially inflating demand). Furthermore, policy experts at the Grattan Institute suggest that curbing these concessions is simply good economic management. They estimate that reducing the CGT discount and limiting negative gearing could save the federal budget billions of dollars annually while marginally reducing property prices and helping more renters become homeowners (Grattan Institute, 2024). Modelling by the Parliamentary Budget Office (PBO) also confirms that adjusting these tax levers could raise substantial public revenue over the next decade (PBO, 2024).
The Counter-Argument
On the other side of the debate, critics warn that tweaking these tax incentives could have unintended negative consequences for the broader housing market.
The Opposition has stated it is highly unlikely the Coalition would support winding back these concessions, arguing that taxing housing further will not solve the core issue of a lack of new building supply. Industry groups have also expressed concern. The Property Council of Australia recently cautioned that reducing the CGT discount for existing properties could force investors to raise rents to cover their costs, further squeezing an already tight rental market and deterring the future development of new housing stock.
What Happens Next?
At this stage, these changes are purely proposals being examined. If they are introduced, it is highly likely that existing property investments would be “grandfathered.” This means the new rules would only apply to future purchases to avoid unfairly penalising Australians who have already invested under the current laws.
