Crypto-asset exchanges: your records, obligations and responsibilities
When filing your taxes, you have to report any income or capital gains from crypto-asset activities on your income tax return. To meet your obligations for proper record keeping, it is strongly recommended that you download and keep any information related to transactions involving your exchange accounts.
It is important to download this information at regular intervals while you still have access to your account. Failure to do so may result in you being unable to access this information if an exchange stops its operations. If you are unable to access your exchange information, it will be difficult to determine your income from crypto-asset activities, or to support amounts filed should the Canada Revenue Agency (CRA) conduct an audit.
