Do you believe that your cryptocurrency transactions are anonymous? This is not the case. Over the past few years, governments have put in place numerous initiatives to better oversee this fast-paced environment and Canada is no exception to the rule.
The tax authorities have conducted an increasing number of audits related to cryptocurrency transactions to ensure that taxpayers meet their tax obligations.

These rules will become effective in Canada as of 2026 and the first reports and information exchanges will take place in 2027.

Revenu Québec is going even further with the creation of the TP-21.4.39, Cryptoasset Return Form.

The form applies to all individuals, corporations and trusts that own cryptocurrency.
Please note that you must still fill out this form if you own cryptoassets, but have not conducted any transactions. Otherwise, you may be subject to penalties.
The tax authorities have carried out extensive work in recent years to inform taxpayers that cryptocurrency transactions are taxable.
