Proposed changes to Australia's capital gains tax aimed at improving housing affordability could impose significant financial and compliance burdens on startups and small business owners, warns CPA Australia, estimating costs could exceed half a billion dollars annually.
- New CGT rules end 50% discount, apply CPI indexation from June 2027
- CPA estimates up to $825 million in one-off and $500 million annual costs
- Startups and small businesses fear increased tax burden without clear valuation guidance
What happened
The Australian government has introduced legislation to overhaul the capital gains tax (CGT) framework, ending a 1999-era 50% discount and replacing it with consumer price index (CPI) adjustments for assets acquired after 30 June 2027. This change is presented as a measure to enhance housing affordability.
While the bill has passed the House of Representatives, it is currently under Senate review. CPA Australia and other stakeholders have voiced concerns, highlighting that owners of startups and small businesses may face substantial unexpected tax liabilities and compliance costs that have not been fully disclosed or examined.
Why it matters
The reforms could drastically increase tax costs for founders, employees, and small business owners who typically acquire shares and assets at nominal values, contrary to the legislation's intention of targeting property investors. CPA Australia estimates the initial one-off costs to establish market values for affected assets could reach as high as $825 million, with ongoing costs annually estimated between $295 million and $542 million, far exceeding government budget estimates.
Key policy details are still undecided, including valuation methodologies and tax rate determination, relying on multiple future ministerial instruments. This uncertainty complicates compliance and planning for affected companies and investors, risking damage to Australia’s startup ecosystem, as highlighted by submissions from FinTech Australia and Innovation Bay calling for tax concessions and better grandfathering provisions.
What to watch next
The Senate committee will conduct public hearings and deliver a report soon, with the potential to amend or reject the current legislation. Stakeholders are particularly awaiting clarified valuation formulas and final policy guidelines that could mitigate some adverse impacts on startups and small businesses.
Investor groups warn the changes could dampen innovation by increasing the cost of capital and reducing incentives for risk-taking. Monitoring the Senate inquiry's outcomes and any government responses to calls for exemptions or carve-outs will be critical for assessing the future viability of venture investment and entrepreneurial growth in Australia.
