The Canada Revenue Agency (CRA) has transitioned to online mail as the default method for business correspondence for most existing businesses and taxpayers.
This change applies to all new business number and program account registrations (for registrations as of May 12, 2025), as well as all existing businesses registered for My Business Account and all businesses who allow a representative (such as Crowe BGK) to access these services on their behalf, whether or not your business has been registered for My Business Account (as of June 16, 2025).
The types of correspondence that have automatically transitioned to online only delivery include but are not limited to notices of assessment/reassessment, letters, audit notifications and statements of account. With the change to online mail, your business correspondence will be considered as received by the business on the date that it is posted to your online account (including notices of assessment/reassessment, for which date the 90-day clock for filing a notice of objection will commence whether you have checked your account or not).
Given this important change, it is crucial that you verify that the email address the CRA has in your account is correct and up-to-date, and that you set up email notifications so that you receive all CRA correspondence regarding your business as it is posted.
Please find the step-by-step guide with instructions on how to set this up, as well as information on how you can opt out of online mail for your business and continue to receive the documents by regular mail.
