Work out CGT on a share sale with parcels

A broker's annual summary says 300 shares were sold. The client bought them in several parcels at different prices. One average purchase figure would hide which units were sold and whether each parcel was held long enough for a discount.

Reconstruct the parcels

For 2025–26, get purchase and sale contract notes, the opening holdings register or prior workpaper, and any corporate-action records. Use the trade date for the sale and each acquisition date for its parcel. Record units, total purchase cost including brokerage, sale proceeds and the source note for both sides. Match the sale against the oldest parcel first unless the records support a specifically identified parcel; split a sale across rows when it crosses parcels.

The holding-period check belongs to each parcel's own dates. Under the repo's 2025–26 rate book, the individual CGT discount is 50% where the parcel qualifies. Apply losses in the capital-gains summary before the discount calculation. A missing purchase cost or date is outstanding evidence; zero would assert a known nil and distort the gain.

Review the register and summary

Upload the notes and prior-year register to an individual Workpapers case. The investment register records the parcels and feeds the share component of item 18 and the capital-gains summary. Check that closing units and cost agree with the holding statement, then follow a disposal row to its source. Resolve a provisional cost base through review points rather than treating the computed total as final.

The 50% figure is from skills/individual-itr-workpaper/reference/rate-book.json for 2025–26; eligibility depends on the parcel facts.
