The Canada Revenue Agency (CRA) now sends most business correspondence online through the My Business Account portal in your CRA account, instead of by paper mail.
To make sure you receive notifications when new mail or important changes occur, add or update your email address in your CRA account.
Why updating your email address matters
Keeping your email address current in your CRA account ensures you receive notifications when:
- New mail (such as notices of assessment, statements, or letters) is available to view
- Important changes are made to your account
If your email address is missing or incorrect, you won’t receive these alerts, even if new mail is posted in My Business Account.
How to add or update your email address
- Sign in to your CRA account to access My Business Account (or Represent a Client if you are an authorized representative)
- From the left navigation menu, select Profile
- In the Notification preferences section, choose Manage notification preferences
- Check your email address and add or update it if needed
New businesses: After you receive your business number and program accounts, register for a CRA account and add your email address.
How to view your online mail
Correspondence is considered received on the date it’s posted in My Business Account. To view your mail:
- Sign in to your CRA account to access My Business Account (or Represent a Client if you are an authorized representative)
- From the left navigation menu, select Correspondence > Mail
- Select and review your mail
