Action Required: Important Change to CRA Online Mail for Businesses

The message below provides details of significant changes recently implemented by the Canada Revenue Agency (CRA). Please read this information thoroughly and confirm your business-related CRA mail preferences via the link provided below. You will receive a follow-up email if we do not receive a response.

The CRA is shifting to online mail as the default method of communicating with businesses. Most businesses will now receive CRA correspondence — including notices and requests for information — exclusively through CRA’s My Business Account (MyBA) portal.

Key details:

• Starting June 16, 2025, the majority of existing businesses will automatically receive CRA correspondence online through MyBA.
• New business and program account registrations are already set up to receive online correspondence by default as of May 12, 2025.
• Correspondence is considered received on the date it is posted to MyBA. This date is critical, as it determines various response deadlines, including CRA requests for documents to support tax return claims and filing objections.
• This change also applies to businesses who have given online access to a representative (e.g., MrA) to view and/or modify information on their behalf via Represent a Client (RaC) — regardless of whether the business has MyBA access.
• Businesses must register to receive email notifications from the CRA to be alerted of new mail to view in MyBA. While MrA may be authorized as a representative through RaC, MrA will not receive any email notifications.
• Email alerts are intended to notify the business owner (or another individual within the business) directly of new correspondence posted in MyBA. Your email address must be up to date in MyBA or you may miss important notifications from the CRA.

Businesses can choose to activate paper mail by notifying the CRA.

Next steps:

To ensure you don’t miss important CRA correspondence, you will need to do one of the following:

• For business owners registered with MyBA: Confirm that your email address is current for all relevant business accounts.
• You can log in to MyBA here.
• Instructions to add an email notification can be found here.
• For business owners not yet registered for MyBA: You can register and enable email notifications from the CRA here.
• To continue receiving paper correspondence from the CRA: You can activate paper mail through your MyBA portal or by submitting Form RC681 – Request to Activate Paper Mail for My Business by mail.
• Note: To maintain paper delivery, you must renew this request every two years and ensure your mailing address is accurate and up to date

Exceptions

Some organizations will continue to receive CRA mail by paper as the default, including:

Charities

• Businesses not registered for MyBA and without an authorized representative (e.g., MrA) via the CRA’s RaC service
• Certain non-resident businesses that do not have a Canadian-resident owner or director and no authorized CRA representative
• For additional information on this change, please refer to CRA’s page for online mail for business.
