Capital gains tax record keeping tool

The capital gains tax (CGT) record keeping tool allows you to record and save your asset and CGT event details, and calculate your capital gains or losses.

For assets with a 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).

You can print a copy of the calculation results for your records and you may remain anonymous throughout the 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.

If you access the tool without a myGov account, you won't be able to save your records to the ATO.

You may need the following information when using the tool:

• asset purchase/acquisition costs
• expense records (such as legal fees, stamp duty, advertising, brokerage)
• borrowing expenses (such as loan application and mortgage discharge fees)
• records of any repairs, maintenance and improvement costs.

If you change or add any details relating to an income year for which you've already lodged a tax return, you may need to amend that return.

For 2018 and later income years Foreign or temporary residents can now use this tool.
