What you can do with this tool
If you use a myGov account to access the tool, you'll be able to save your CGT records to the ATO for use in your tax return. This will save you time when you complete your tax return.
For assets with a capital gains tax (CGT) event date, the tool works out your net capital gain or loss amount for the year. It will apply the CGT calculation method that gives you the best result (the smallest net capital gain).
The tool results are based on the information you provide at the time. You should use the results as an estimate and for guidance purposes only.
