As of June 16, 2025, the Canada Revenue Agency (CRA) has changed its default correspondence method for most businesses to online-only. This means important notices will no longer arrive by paper mail unless you opt out. All correspondence is presumed received on the date it is posted to CRA’s My Business Account, which can create issues if time-sensitive messages go unnoticed.

To receive email notifications when new mail is posted online, businesses must provide CRA with an email address and register it for each applicable program (e.g., GST/HST, payroll, corporate tax). However, even without registering for notifications, businesses will still be transitioned to online mail, and the presumption of receipt applies regardless.

What can you do?

• Ensure you have access to My Business Account and monitor it regularly.
• If you prefer paper mail, opt out by updating your settings in the Profile section of My Business Account or by submitting Form RC681 – Request to Activate Paper Mail for My Business. Note: CRA may still send online mail during processing, and communications posted within 30 days of your request are considered received on the posting date.

Requests can only be made by someone with signing authority (owner, director, or legal representative). Paper mail preferences must be renewed every two years, and new accounts require separate requests.

Action: Decide your preferred method and take steps now to avoid missing critical CRA correspondence.
