Treasurer Jim Chalmers is expected to secure tax-reform measures in the upcoming federal budget scheduled for May 12, 2026 [1].

These reforms target negative gearing and capital gains tax to improve housing affordability and ensure long-term fiscal sustainability. The measures would likely be grandfathered, meaning changes would apply to new acquisitions rather than those who already hold assets [2, 3].

Chalmers is expected to attend last-minute budget meetings this week to finalize these reforms, Andrew Clennell of Sky News Australia said [4]. The treasurer recently returned from a G20 finance ministers meeting in Washington, where he said he felt more certain than ever of the need for major reform in the May budget [5].

Despite the push for reform, Chalmers has cautioned against expectations of a massive financial windfall. "People shouldn't expect there to be this huge amount of new revenue," Chalmers said [6].

Reports on the scale of the reform vary. Some sources suggest senior ministers are expected to sign off on a reduction in capital gains tax concessions and an overhaul of negative gearing [2]. However, other reports indicate that Chalmers has done little to quell the ongoing debate as the budget deadline approaches [7].

The government's strategy appears to balance the need for systemic change with the desire to avoid market instability. By grandfathering existing properties, the administration aims to reduce the tax incentives for property speculation without triggering a mass sell-off by current homeowners [2, 3].

"People shouldn't expect there to be this huge amount of new revenue."

The focus on grandfathering suggests the Australian government is attempting to address the housing affordability crisis without alienating current property owners. By targeting new investments, the administration seeks to curb the growth of the investor-led market while maintaining political stability ahead of the May 12 budget delivery.
