How long should you keep your income tax records?
Generally, you should keep your supporting documents for six years. Even if you do not have to attach certain supporting documents to your return, or if you are filing your return electronically, keep them in case we select your return for review. We may request documentation other than official receipts as proof of any deduction or credit you claim, such as cancelled cheques or bank statements. For more information, see the General Income Tax and Benefit Guide and Information Circular IC78-10R5, Books and Records Retention/Destruction.
