Online Mail Now the Default for Businesses

Beginning May 12, 2025, CRA will transition to online mail as the default for most business correspondence, delivering notices and updates through My Business Account instead of by paper mail. They have produced a timeline for the transition to online mail:

May 12, 2025: new business and program account registrations receive most of their business correspondence online in My Business AccountJune 16, 2025: existing businesses with a My Business Account, or who have authorized a representative to access their information through CRA's Represent A Client portal started receiving online mail. This is a problem for businesses that do not have an online account, but use an authorized representative, because those representatives are unlikely to monitor the client's online mail.

Existing business without a My Business Account and without an authorized representative will continue to get paper mail, as will charities and non-resident businesses.

Requesting Paper Mail From CRA

Starting May 12, 2025, paper mail can be requested (and the request must be made every 2 years to keep receiving paper mail):

in your CRA My Business Account, orby completing, signing and mailing to your Tax Centre form RC681 - Request to Activate Paper Mail for Business. This will be a problem if there is a Canada Post strike.

The request for paper mail can only be made by an individual with signing authority such as an owner or their legal representative.
