CANADA REVENUE AGENCY (CRA) ONLINE SERVICES - UPDATES

Effective May 12, 2025, the CRA will begin transitioning to online mail as the default method for sending most business correspondence. Instead of traditional paper mail, notices, letters, and statements will now be delivered through the My Business Account portal. 

This change applies to: 

• All newly registered business numbers and program accounts 

• Existing businesses enrolled in My Business Account 

• Businesses with authorized representatives using Represent a Client 

Businesses not registered for My Business Account, certain charities, and non-resident businesses without a Canadian-resident owner or authorized representative will continue to receive paper mail. 

The CRA will implement the transition to online mail in phases as follows: 

• May 12, 2025: Online mail becomes the default for new business and program account registrations. 

• June 16, 2025: The default shifts for existing businesses registered with My Business Account. 

To view any correspondence, employers must: 

1. Sign in to My Business Account or Represent a Client 

2. Navigate to Correspondence > Mail 

3. Select and review your documents 

Mail is considered received on the date it's posted to the employer’s online account. 

The CRA has enhanced the My Business Account portal to improve usability: 

• Enhanced message filtering and sorting 

• Quick links like “Access services,” “Reply,” “Proceed to pay,” and “Submit document” 

• Ability to easily switch between multiple business accounts 

Employers may opt out of online mail, but only by request. To do so: 

• Sign in to My Business Account and request paper mail, or 

• Complete and mail Form RC681 – Request to Activate Paper Mail for My Business 

Only individuals with signing authority (owners, directors, or legal representatives) can make this request. Paper mail requests must be renewed every two years, and addresses must remain up to date. Any undeliverable mail will result in a return to online mail. 

Employers must ensure: 

• Their email address is current in My Business Account. This allows the CRA to notify them when new mail arrives. 

• New business owners should register for My Business Account immediately after receiving their business number and program account to avoid missing important messages.
