As the ATO’s data-matching capabilities increase, they are paying close attention to capital gains made on shares, property and cryptocurrency.
Therefore, it’s important to let us know about any asset disposals (which can include an asset’s sale, loss or destruction) and to keep records relating to CGT events, including asset disposal, for at least five years after the year in which the event occurred (and maybe longer if you make a capital loss). Good records will also help to work out a capital gain or loss correctly.
