The 2026 Australian federal budget introduces modest changes to capital gains tax, family trusts, and negative gearing. However, economists argue these adjustments barely scratch the surface and call for broader tax reforms to better support the startup ecosystem and the wider economy.
- Minor CGT adjustments will yield limited budget improvement by 2031
- Stamp duties hinder housing mobility and should be replaced by land taxes
- More effective taxation of windfall profits and carbon emissions needed
What happened
The 2026 Australian federal budget implemented incremental reforms to capital gains tax (CGT), family trusts, and negative gearing. These changes aim to modestly strengthen public finances but are projected to increase the budget surplus by only 0.2% of GDP over the next five years. Most new revenue is expected to arise from minimum taxes imposed on family trusts.
Despite their high-profile nature, these adjustments fall short of addressing the more fundamental tax challenges facing Australia. Economists highlight that a broader, more structural tax reform is required to support startup innovation, economic flexibility, and fiscal sustainability.
Why it matters
Australia’s reliance on property stamp duties creates significant barriers to housing mobility, imposing hefty upfront costs on homeowners relocating or trading properties. These duties can amount up to $60,000 on a $1 million home depending on the state. Transitioning to annual land taxes could remove these burdens, promoting a more dynamic housing market with less economic friction.
In addition, Australia’s current tax system insufficiently targets windfall and monopoly profits, such as those from resource extraction and digital platform dominance, missing opportunities to capture fair revenue. Furthermore, the lack of an effective, broad carbon price means that emissions are curtailed inefficiently and at higher economic costs. Addressing these gaps is crucial for fiscal health, economic fairness, and environmental objectives.
What to watch next
Observers should monitor government initiatives aimed at phasing out stamp duties and introducing annual land taxes, which will require careful negotiation due to potential short-term revenue losses for states. Federal support or incentives could accelerate these reforms but political will remains a key variable.
In parallel, attention will focus on proposals for a revamped business tax system, such as adopting a cash flow tax that incentivizes investment while capturing excess profits, and the implementation of a comprehensive carbon pricing mechanism. These reforms would align tax policy with sustainable growth goals and global competitiveness, especially for Australia’s high-potential startup sector.
