Australia’s startup sector has become an unexpected flashpoint in the Albanese government’s post-budget tax agenda, with ministers now signalling that the proposed capital gains tax overhaul may need startup-specific adjustments. The controversy follows plans to replace the existing 50% CGT discount with cost base indexation and introduce a 30% minimum tax on real capital gains from 1 July 2027. The issue has gained momentum because founders, investors and employee-equity advocates argue the reform could weaken the incentives that underpin early-stage company creation.
Budget Context
The official Budget papers frame the CGT changes as part of a wider package aimed at improving housing affordability, shifting tax support away from established residential property and making asset income taxation more consistent. They also state that the government will consult stakeholders on key design issues, including the treatment of early-stage and startup businesses because of the sector’s distinct characteristics. Alongside the contentious CGT measure, the Budget includes startup-relevant initiatives such as loss refundability for small startup companies, expanded venture capital incentives and broader business tax reforms intended to encourage risk-taking.
Startup Backlash
Founders and investors say the design problem is straightforward: many startup shares begin with a negligible or zero cost base, which means indexation may offer little practical benefit when a successful exit occurs. SmartCompany and Startup Daily reported that the backlash has widened beyond venture capital circles to include concerns about employee share ownership plans, hiring, retention and the risk of startups moving talent or headquarters offshore. On LinkedIn, Square Peg co-founder Paul Bassat warned that higher CGT settings could discourage company formation, while other founders and industry bodies argued that the policy could make Australia less competitive for ambitious technology companies.
Government Response
Assistant Treasurer Daniel Mulino has acknowledged the sector’s concern, describing startups as a special case because gains can arise from very low cost bases rather than from inflation-adjusted asset appreciation. Media reports indicate the government is reluctant to create broad carve-outs, but is considering whether changes to cost-base calculations could soften the impact for founders and investors. The government has not yet released detailed consultation terms, leaving open whether any adjustment will cover founders, early employees, venture investors or employee share schemes.
Broader Industry Effects
The debate is not limited to tax rates or founder exits, because startup compensation often relies on equity when young companies cannot match large-company salaries. Employee Ownership Australia has said it has raised concerns with the Treasurer and Assistant Treasurer, warning of unintended consequences for employee ownership and early-stage talent incentives. Legal and advisory commentary has also highlighted the possibility that unchanged rules could encourage some founders to sell before the July 2027 start date, adding urgency to the consultation process.
The government’s challenge is to preserve the broader objectives of its housing and tax reform package while avoiding collateral damage to innovation policy. The Budget papers already recognise that startups have unique features, but the industry is now looking for concrete design choices rather than general assurances of consultation. Unless the government can clarify the treatment of startup equity, the CGT debate is likely to remain a live political and economic issue for founders, investors and policymakers through the next stage of reform.
