How to Contest a Revenu Québec Assessment: Legal Survival Guide for Entrepreneurs

Receiving an assessment or reassessment from Revenu Québec or the Canada Revenue Agency (CRA) often triggers panic. Yet a notice of assessment is not an absolute truth: it is an administrative interpretation that can be contested.

At Twin Lisbet, we transform tax defense into an offensive strategy to protect your capital and reputation. Here are the critical steps to regain control.

1. Fatal Errors During a Tax Audit: Why Your Silence Is Golden

The verification phase is when most disputes are lost. The auditor is not your advisor; their role is to maximize state revenue.

  • Involuntary self-incrimination: Providing unrequested documents or answering vague questions without preparation can open “Pandora’s boxes” of
  • The role of the lawyer from day 1: Mandating Twin Lisbet at the start of the audit establishes a “legal screen.” We filter information requests to ensure the tax authorities do not exceed their powers under the Tax Administration Act.

2. The Power of Opposition: The 90-Day Deadline Is Sacred

If the assessment has already been issued, you generally have 90 days to file a Notice of Opposition. Beyond that deadline, your chances of contestation diminish drastically.

  • What is Opposition? It is an internal review by a different agent from the one who conducted the audit.
  • Surgical analysis: We do not simply say “we disagree.” We draft arguments based on recent jurisprudence from the Tax Court of Canada, challenging the facts or the auditor’s interpretation of the law.

3. Contesting Arbitrary Evaluation Methods

Often, the tax authorities use “arbitrary assessment” or “market value” methods that do not reflect the reality of your business or sector (e.g., petroleum trading or mining resources).

  • Denied business expenses: We intervene to prove the direct link between your expenses and your income generation, a frequent conflict zone for entrepreneurs.
  • Transactions between related entities: If the tax authorities question your transfer pricing or inter-company loans, we restructure the evidence to validate the legality of your tax arrangements.

4. Recourse to the Tribunal: When Negotiation Fails

If the Notice of Opposition does not yield the expected results, the next step is an appeal before the Court of Québec or the Tax Court of Canada. At this stage, Twin Lisbet’s expertise in complex litigation becomes your greatest asset. We handle your file with the same rigor as a class action: exhaustive evidence preparation, precise examinations, and impactful pleadings.
