You have the absolute right to change your tax lawyer or accountant at any point during a CRA dispute. To do this securely, you must use the CRA’s online “Authorize a Representative” (Auth-A-Rep) system to grant your new law firm Level 2 access, while simultaneously cancelling the access of your former representative.
Battling the Canada Revenue Agency (CRA) is a high-stress endeavour. Whether you are fighting a personal income tax reassessment in Edmonton or defending a massive corporate audit in Ottawa, having complete trust in your legal representation is vital. Sometimes, relationships with accountants or tax lawyers break down. Perhaps they are not communicating effectively, or maybe your case has escalated to the Tax Court of Canada and requires a specialized litigation firm. Changing your representative mid-dispute is completely legal and very common. However, the federal government has strict privacy protocols. You must properly update your authorized representatives to ensure sensitive financial data does not fall into the wrong hands and that your new lawyer receives all critical CRA correspondence on time.
The days of mailing paper forms are largely over. The CRA now relies heavily on digital authorization. Managing your representative profile correctly ensures a seamless transition without missing any crucial 90-day legal deadlines for your Notice of Objection or Appeal.
Step-by-Step Process for Changing Your Tax Representative in Canada
Transitioning to a new law firm requires coordination. You must ensure the new firm is fully authorized before the old firm completely drops your case, to avoid missing vital letters from the CRA Appeals Division.
Step 1: Retaining the New Law Firm
💼 Before firing your current representative, secure your new legal team. You will sign a formal retainer agreement with the new Canadian law firm. Your new lawyer will then provide you with their RepID (a unique federal identification number for tax professionals) or their firm’s BN (Business Number), which you will need for the CRA portal.
Step 2: Accessing the CRA Portal
Log into your CRA My Account (for individuals) or My Business Account (for corporations) using your secure banking sign-in or GCKey. Navigate to the “Profile” section and select “Authorized Representatives.” Here, you will see a list of every accountant, bookkeeper, and lawyer who currently has permission to view your federal tax data.
Step 3: Cancelling the Old Representative
Locate the name of your former lawyer or accountant on the active list. Select “Cancel Authorization.” This change is instantaneous across the entire federal system. From that exact second, your former representative can no longer view your files or speak to CRA auditors on your behalf.
Step 4: Authorizing the New Lawyer
Click “Add a Representative” and input the RepID provided by your new law firm. You must select the level of authorization. For a law firm fighting an active dispute, you must grant Level 2 Access (Update and Communicate). This allows the lawyer to submit documents, file objections, and negotiate directly with the CRA Appeals Officer on your behalf.
Step 5: Facilitating the File Transfer
🗂 Your new lawyer will send a formal “Direction to Transfer File” letter to your old representative. Under Canadian law society rules, your previous lawyer is legally obligated to hand over your file, including all CRA correspondence and working papers. Once the new firm has the file, they will officially notify the assigned CRA Appeals Officer or the Department of Justice that they are taking over the dispute.
Understanding CRA Authorization Levels
| Authorization Level | What the Representative Can Do | Best Used For |
|---|---|---|
| Level 1: View Only | Read tax returns and notices, but cannot make changes. | Basic bookkeepers or financial advisors. |
| Level 2: Update | Submit documents, negotiate settlements, and file objections. | Tax lawyers and CPAs fighting active CRA disputes. |
| Level 3: Delegate | Manage your account and authorize other representatives. | Corporate directors or power of attorney holders. |
How Much Does Changing Lawyers Cost?
While the CRA does not charge any fees to update your representative profile online, the administrative and legal costs of changing firms can be notable.
- CRA Authorization Fee: $0 CAD. The digital Auth-A-Rep system is entirely free.
- Settling the Old Bill: You must usually pay any outstanding invoices to your former lawyer before they release your physical file, which can range from a few hundred to thousands of CAD.
- New Law Firm Retainer: Hiring a new tax lawyer to take over an active dispute typically requires an upfront retainer of $3,000 to $10,000 CAD, depending on the complexity of the audit.
- File Review Fees: Your new lawyer will charge for the hours required to read through the old file and get up to speed.
How Long Does the Process Take?
The digital side of changing representatives is incredibly fast. Updating the CRA My Account portal takes less than 5 minutes, and the access changes are processed by the CRA servers overnight. However, the physical transfer of your legal file between law firms typically takes 1 to 2 weeks. It is crucial to manage this timeline carefully if a 90-day deadline for a Notice of Objection is rapidly approaching.
Frequently Asked Questions (FAQ)
Does changing my lawyer extend my CRA deadlines?
Absolutely not. The CRA’s strict 90-day deadline to file a Notice of Objection remains fixed, regardless of your legal representation. Your new lawyer must meet the existing deadlines to protect your rights.
Can my old lawyer refuse to give me my tax files?
Generally, lawyers can place a “solicitor’s lien” on your file if you refuse to pay your final bill. However, they cannot withhold documents if doing so would cause you severe prejudice, such as missing a looming court deadline.
Can I authorize a representative using a paper form?
Yes. If you cannot access the online portal, you can fill out and mail CRA Form AUT-01. However, physical forms take 4 to 6 weeks to process, which is often too slow during an active dispute.
Will the CRA notify my old accountant that they are fired?
No. When you cancel authorization online, the CRA simply revokes their digital access. The government will not send them a notification letter. It is your responsibility to inform them professionally.
