tarting in spring 2025, the Canada Revenue Agency (CRA) will transition to online mail as the default method of delivering most business correspondence. This means you'll start receiving most of your business notices and other correspondence through the CRA's secure online portal, My Business Account, instead of by mail.

This change applies to all:

• new business number and program account registrations
• existing businesses registered for My Business Account
• businesses who have a representative that accesses the CRA's services on their behalf via Represent a Client

This change is part of the CRA's ongoing efforts to improve service delivery by making it faster, easier, and more secure for businesses to manage their tax obligations online. Online mail means businesses will need to sign in to My Business Account to receive correspondence, such as a notice of assessment. For more information you can visit online mail for business.

How to prepare for this change – make sure your email address is in your account and up to date

To prepare for the switch to online mail, the CRA recommends signing into My Business Account and making sure your email address is up to date. This allows the CRA to notify you when important changes are made on your account and when you have mail to view in My Business Account. You can have up to three email addresses on file for each program account, so you can also add your representative, accountant, or other authorized individuals. Without an updated email address, you may miss important notifications about updates and correspondence.

Owners of new businesses should register for My Business Account and provide a valid email address after they register for their business number and program accountss, so they do not miss notifications about updates and correspondence.

Business correspondence

Business correspondence refers to notices, letters, forms, statements, and other documents that the CRA sends to communicate important information about your business tax account or returns.

Businesses registering for a new business number or program account will need to register for My Business Account to access their business correspondence.

With the change to online mail, your business correspondence will be considered as received on the date that it is posted to your My Business Account. To access, view, print, or download your business correspondence, follow the steps below:

Step 1: Sign in to My Business Account (if you are an authorized representative sign into Represent a Client
Step 2: From the navigation menu on the left, go to "Correspondence" heading and select "Mail"
Step 3: Select and review your mail

Exceptions

Existing businesses not registered for My Business Account through the business owner or an authorized representative (via Represent a Client) will continue to receive their CRA correspondence by paper mail.

Charities will continue to receive their CRA correspondence by paper mail unless they sign up to receive online mail.

Non-resident businesses that do not have access to My Business Account through their representative or an owner that is a Canadian resident will continue to receive their correspondence by paper mail.
