Missed a CRA business notice? Check online mail before the next deadline

Open the actual correspondence

CRA moved most business correspondence to online delivery by default beginning in 2025. Check the business's mail settings and access to My Business Account. An email notification and the correspondence available in the account are different things; review the actual notice before deciding what it requires.

Sign in through the official CRA service you normally use. If an unexpected message raises a concern, verify it through the official account rather than treating the message itself as proof.

Turn the notice into a clear next action

• Identify the business account and reporting period.
• Read what information, payment or response is requested.
• Record any stated response date in an appropriate planning system.
• Agree who will prepare and review the response.
• Keep submission evidence and follow-up correspondence.

A general annual deadline list may not contain a response date created by an individual notice. Do not assume the next routine filing deadline is also the deadline for answering a specific request.

Agree who checks the account

If an accountant or bookkeeper also has authorized access, agree who monitors correspondence and informs the owner. Avoid assuming another person has already read a notice simply because they handle tax preparation.

Keep calendar reminders and CRA notices distinct

Compliance Calendar helps organize recurring deadlines and related notes. It does not connect to CRA accounts, monitor CRA mail or automatically calculate every notice-specific response period. Use it alongside the official account and your agreed correspondence routine, and ask for advice when a notice needs interpretation.
