Australian equity investors are facing a critical portfolio decision as the clock ticks down to June 30, 2027, when new capital gains tax (CGT) indexation rules will replace the current 50% discount system.
The policy shift has triggered a wave of tax-loss selling and strategic rebalancing among retail and institutional holders alike, who are racing to determine which regime yields the lower effective tax rate for their specific holdings.
The core dilemma lies in the trade-off between locking in gains under the existing 50% discount versus waiting for the new indexation mechanism, which adjusts the cost base for inflation but removes the blanket discount.

For investors with substantial unrealized profits, the math is complex: those with high marginal tax rates and assets purchased during periods of low inflation may find the current discount more favorable, while others with older, low-cost bases could benefit from indexation.
However, the removal of loss offsets under the new framework complicates the calculation, potentially pushing effective tax rates as high as 80% for certain investor profiles, according to analysis of the legislation’s mechanics.
Market activity reflects this uncertainty.
