For Canadian businesses, staying on top of Canada Revenue Agency (CRA) updates is essential to ensuring smooth operations and full compliance. Earlier this year, the CRA made a significant shift: most correspondence is now sent electronically through My Business Account rather than by paper mail.
This change impacts all business owners and their authorized representatives. Missing a notice could mean missed deadlines, penalties, or added complications during CRA audits. Understanding how to adapt is crucial—and an experienced accounting firm can help you stay on track.
The CRA’s New Digital-First Approach
As of June 16, 2025, the CRA has made online mail the default communication method for businesses. Instead of receiving letters or statements in the mail, you will find them electronically in your My Business Account. The CRA also sends optional email alerts to notify you when new correspondence is available.
While this improves efficiency, it requires businesses to take a more proactive role in monitoring their accounts. That’s where a trusted tax accountant can provide valuable support, ensuring that no important communication is overlooked.
Important Deadlines Every Business Should Note
The CRA introduced two key deadlines in 2025, marking the shift to mandatory online mail through My Business Account.
- May 12, 2025: Online mail became the default for newly registered business numbers and program accounts (such as GST/HST, payroll, and corporate tax Canada filings).
- June 16, 2025: Online mail became the default for all existing business accounts, including those managed through the Represent a Client portal.
These changes affect virtually every business in Canada, whether you are a small company or a larger corporation. Partnering with a qualified business advisory team ensures you don’t miss key CRA mail and deadlines.
Steps to Stay Ahead of the Transition
To ensure a smooth adjustment to CRA online mail, business owners should:
- Confirm Access: If you already receive CRA communications digitally, confirm that you can log in to your My Business Account.
- Register if Needed: If you are not yet enrolled, create a My Business Account as soon as possible.
- Verify Emails: You can add up to three email addresses per program account for notifications.
- Check Regularly: Build in a routine, supported by your bookkeeping services or accountant, to review correspondence and notices.
- Paper Mail Option: If preferred, you can opt in to paper mail by filing Form RC681. Keep in mind, this must be renewed every two years.
Working with a tax advisor or consulting firm can simplify this process and provide peace of mind that no important notice goes unseen.
The Risks of Missing CRA Online Mail
Electronic communications mean faster delivery, but also fewer reminders arriving in your mailbox. Businesses that fail to adapt may face missed deadlines, delayed responses, or complications if audited by the CRA.
