30 June 2027 valuation

Under the 2027 capital gains changes, shares and ETF units you still hold at the end of 30 June 2027 are treated as sold that day at market value and bought back on 1 July. Nothing goes on your 2026-27 return: the gain or loss waits until you really sell, so every later sale needs each parcel's value.

Until then this page shows what you hold today, with each parcel's cost base, so you can fill any gaps in your history before the date. ATO: capital gains tax reform
