Australia’s Biggest CGT Shake-Up in Decades is Coming
The 2026-27 Federal Budget has proposed the most significant overhaul of Australia's capital gains tax system in nearly three decades. From 1 July 2027, the familiar 50 per cent CGT discount, a cornerstone of investment planning since 1999, is set to be replaced by an inflation-adjusted indexation model accompanied by a new 30 per cent minimum tax on real gains. For property investors, shareholders, and anyone sitting on long-held assets, the changes will fundamentally alter how investment returns are calculated and taxed. With transitional rules, new build carve-outs, and the surprise inclusion of pre-1985 legacy assets all forming part of the package, understanding the detail now, well ahead of the 2027 start date, will be essential.
