The Australian Greens have agreed to support the Australian Labor Party's tax reform package involving capital gains tax and negative gearing.

This agreement resolves a legislative deadlock in Canberra, allowing the government to move forward with controversial tax changes that had previously faced significant opposition. The deal ensures the passage of reforms aimed at altering how investment properties and assets are taxed.

In exchange for their support, the Greens secured an eight-week extension [1] of the inquiry into the National Disability Insurance Scheme (NDIS). The extension provides more time to examine the government's proposed overhaul of the disability support system.

Beyond the NDIS timeline, the agreement included a super-fund amendment as part of the concessions required by the Greens. The deal was reported Tuesday, June 23, 2026, as a strategic compromise between the two parties to ensure the tax bill's success in Federal Parliament.

The tax reforms specifically target negative gearing and capital gains tax, two of the most debated elements of the Australian tax code. By securing the support of the Greens, the Labor Party avoids a potential defeat of the bill in the Senate.

Legislators in Canberra have long debated these reforms as a means to address housing affordability and tax equity. The eight-week extension [1] of the NDIS inquiry serves as a critical win for the Greens, who have pushed for more rigorous scrutiny of how the NDIS reforms will impact participants.

“The Greens will support Labor's controversial tax reforms in exchange for an eight-week extension of the NDIS inquiry.”

This deal represents a tactical trade-off where the Labor government prioritizes fiscal policy over the speed of administrative reform. By conceding a delay in the NDIS inquiry, Labor secures the legislative numbers needed to pass high-stakes tax changes that would likely have failed without the Greens' bloc. For the Greens, the extension provides a window to intensify advocacy for disability services before the government implements its overhaul.
