Key Points
New 30% CGT base rate replaces 50% discount from July 1, 2027.
Property renovation strategy faces punitive tax hit when selling and boosting super.
$372 billion in super-linked assets potentially affected with $55 million annual tax impact.
Treasurer faces mounting pressure from industry and opposition to reverse the changes.
Australia’s capital gains tax system is about to change dramatically. From July 1, 2027, the government will scrap the current 50 per cent discount and introduce a new 30 per cent base rate alongside an inflation-adjusted rate. The shift will hit share investors, property renovators, and superannuation funds, triggering fierce pushback from industry bodies and opposition politicians demanding the changes be reversed.
How the new CGT rules work
Until now, if you held an asset for more than 12 months before selling it, you paid tax on only 50 per cent of the profit at your marginal income tax rate. From July 1, 2027, that changes. The new system introduces a 30 per cent base rate on capital gains, alongside an inflation-adjusted rate that complicates the calculation. A $1 million share profit that once triggered a 50 per cent discount now faces a steeper tax bill under the new formula.
Property renovations and super funds face steep bills
Property owners who sell and reinvest in renovations will face a “massive trap,” according to industry analysis. The strategy of selling an investment property and boosting superannuation with the proceeds before retirement will trigger punitive tax hits when the new CGT regime starts. Superannuation funds holding assets in trusts face particular pressure, with $372 billion in super-linked assets potentially affected and an estimated $55 million annual tax impact.
Treasurer faces mounting pressure to reverse the changes
Treasurer Jim Chalmers is under intense pressure to axe the new “stealth super tax.” The self-managed superannuation fund industry’s peak body has joined calls for a reversal, and opposition politicians argue the changes will hit millions of ordinary Australians saving for retirement. The government says super funds are excluded from the new rules, but confusion over the exact scope has fuelled the backlash. The changes are part of Labor’s broader push to address what it calls intergenerational wealth inequality.
What investors need to do now
Financial advisers recommend reviewing your investment strategy before July 1, 2027. If you hold unlisted assets, businesses, or property, you may need a professional valuation before 2027 to lock in current values under the old rules. Selling high-value shares or property before the deadline could save thousands in tax, but timing the market carries its own risks. Speak to a tax adviser to model your specific situation.
Final Thoughts
The July 2027 CGT overhaul will reshape how Australians pay tax on investment gains. With billions in super assets at stake and industry bodies demanding a rethink, the final shape of the rules remains uncertain. Investors should act now to understand their exposure and plan accordingly.
