You can use Form T1013, Authorizing or Cancelling a Representative, to:
If you have a legal representative, you do not need to complete Form T1013 to update him or her as your legal representative on your account. The legal representative has to provide a copy of the legal document that names him or her as acting in that capacity. A legal representative can be someone with your power of attorney, your guardian, or an executor or administrator of the taxpayer's estate.
You do not need to complete this form if another person (such as your spouse or common-law partner, a friend, or your accountant) is only preparing your income tax return. However, if you want us at the CRA to deal with that person as your representative for income tax matters, you must complete Form T1013.
You do not need to complete a new form every year if there are no changes.
If you are preparing returns for several tax years at once, only one Form T1013 is required.
If you want to authorize a representative for your business accounts, complete the RC59 Business Consent Form.
You can authorize your representative to deal with us through our online services for representatives. You have to provide the RepID if your representative is an individual, the GroupID if your representative is a group of individuals, or the Business Number (BN) if your representative is a business. You also have to provide the name associated to the RepID, GroupID, or BN.
You can do this by completing part 2 of the Form T1013 (see example) or by using the Authorize my representative service found under our My Account online service.
Our online services do not have a year-specific option. Therefore, your representative will have access to all tax years.
