Important: This calculator is a rough guide only, intended to illustrate the potential difference in outcome between the current 50% CGT discount and the proposed indexation method under anticipated legislative changes. The indexation method and the 30% minimum tax rate shown are based on proposals that have not yet been enacted — the final law may differ. This does not constitute tax advice and should not be relied upon for financial decisions. Your actual CGT liability will depend on your full circumstances, applicable exemptions, and cost base adjustments. You should obtain advice from a registered tax agent or qualified accountant before making any decisions.
