Contacting us on someone else's behalf
Only authorized representatives are able to call on someone else's behalf. Representatives are individuals you authorize to help manage your business' tax information. It's important to know who your representatives are and what information they have access to. You can remove representatives that are not current by using My Business Account.
Authorized representatives can do one or more of the following:
- Access your personal tax information, tax assessment or reassessment
- Get information about your business tax accounts
- Update some of your business number and program account information
- Access or update your non-resident tax account information
- Access or update trust account information
- Verify their authorization by referring to their Client List in Represent a Client (not applicable for non-resident accounts or trust accounts)
To learn more, go to New: Confirm a representative using My Account or My Business Account.
