Questions and answers
Which CommSec file does FiscalFox need?
Use the confirmations export for domestic trades. A portfolio profit figure or Transaction Summary total cannot identify every acquisition parcel.
Is the CommSec profit figure my Australian taxable gain?
Use it as a cross-check. Australian CGT depends on the parcels, original costs, AUD conversions, capital losses and applicable discount; the calculator rebuilds those figures from the records.
Do I need earlier purchases as well as this year’s sales?
Yes, whenever a sale uses shares bought before the income year. Include the original acquisitions and any relevant transfers, reinvestments or fund cost base adjustments.
