Filing a Service Complaint: How to Address Unfair Treatment by CRA Staff – A Complete Guide by a Montreal CPA Firm Near You

Introduction
While CRA has significant authority to audit, reassess, and collect taxes, taxpayers also have the right to fair, respectful, and professional treatment. When CRA agents act unprofessionally, delay your file, ignore your documentation, miscommunicate instructions, or apply procedures improperly, you have the right to file a Service Complaint. Many Canadians don’t realize this is a formal process with real consequences: CRA must investigate the complaint and correct improper behavior. This guide explains how CRA’s Service Complaint process works, when you should consider filing one, and how to structure a complaint that gets results.
Legal and Regulatory Framework
CRA’s Service Complaint process is governed by the Taxpayer Bill of Rights, particularly:
Right 5: To be treated professionally and courteously
Right 6: To receive complete, accurate, and timely information
Right 8: To lodge a service complaint
Right 15: To have a complaint resolved promptly
The complaint process is not for disputing tax assessments. Instead, it is designed to address service issues, including mistreatment, administrative delays, lost documents, rude behavior, failure to follow CRA guidelines, and unreasonable timelines. Complaints are reviewed by CRA’s internal Service Feedback Program and can be escalated to the Office of the Taxpayer Ombudsperson.
Key Court & Policy Insights
While courts do not decide service complaints, jurisprudence emphasizes procedural fairness. In Hickman Motors v. Canada, the Supreme Court held that CRA must act fairly in its decision-making. The Ombudsperson has published multiple reports criticizing CRA for poor communication, unreasonable delays, and inconsistent procedures—showing service complaints are taken seriously.
When You Should File a CRA Service Complaint
You should file a complaint when CRA:
Ignores or loses your documents
Fails to return calls or respond to letters
Provides contradictory instructions
Delays your return, refund, or objection without reason
Treats you disrespectfully
Uses aggressive or inappropriate language
Refuses reasonable extensions
Mishandles your Taxpayer Relief request
Repeatedly transfers your call without answering your questions
Applies procedures inconsistently
If your concern relates to tax correctness, file a Notice of Objection instead. Complaints are purely for service.
How to File a Service Complaint (Step-by-Step)
Step 1: Attempt to Resolve the Issue With CRA First
Call the agent or supervisor. Explain the service issue calmly. Many cases are resolved at this stage.
Step 2: Submit a Formal Service Complaint (Level 1)
Use Form RC193 or submit through CRA My Account / My Business Account. Clearly describe:
What happened
Why the service was unacceptable
Dates, times, and names of agents involved
How it affected you or your business
What outcome you expect
Attach supporting documents (emails, call logs, letters).
Step 3: Escalate to Level 2 (CRA Complaints Intake Centre)
If Level 1 does not resolve the issue, request Level 2 review. A specialized team will review staff conduct and service failures.
Step 4: Escalate to the Taxpayer Ombudsperson (Level 3)
If CRA still fails to address the issue, file a complaint with the Office of the Taxpayer Ombudsperson. This office is independent from CRA and investigates systemic and individual service failures.
What a Service Complaint Can Achieve
Faster processing of delayed files
Correcting CRA administrative mistakes
Reinstating denied benefits caused by CRA error
Replacing problematic auditors
Clarifying misapplied procedures
Securing written apologies from CRA
Reopening files mishandled due to service issues
While it cannot reverse assessments, it can fix the process affecting your file.
What a Service Complaint Cannot Do
It cannot cancel tax owing
It cannot remove penalties or interest
It cannot override CRA’s legal interpretation of tax law
It cannot reverse audit results (use Objection instead)
It cannot stop collections (payment plans are required)
How to Write an Effective Service Complaint
1. Stay Professional and Factual
Avoid emotional language. Focus on facts.
2. Provide Dates, Names, and Evidence
The strongest complaints document every interaction.
3. Explain the Impact
Describe delays, financial harm, stress, or missed deadlines caused by CRA’s service failure.
4. Include Your Desired Resolution
E.g., reassignment of an auditor, expedited processing, corrected communication.
5. Attach Proof
Call logs, copies of letters, audit proposals, incorrect CRA instructions, etc.
Examples of Valid Service Complaints
CRA lost documents twice, delaying a refund for months
Auditor demanded unreasonable deadlines despite medical issues
CRA agent provided incorrect tax instructions leading to reassessment
Collections officer used threatening or inappropriate language
CRA failed to process a Taxpayer Relief application for over 12 months
These are legitimate reasons to file a complaint.
When to Avoid Filing a Complaint
Do not file a complaint because you disagree with CRA’s audit results. That requires:
Notice of Objection
Tax Court appeal
Service complaints are for behavior and administration, not tax law disagreements.
