📑 CRA Income Tax Objection: Complete Guide to Disputing Your Assessment
If you disagree with your Notice of Assessment or Reassessment, you have the legal right to file an income tax objection with the Canada Revenue Agency (CRA). This is the first formal step in challenging a tax decision.
🧭 What Is a CRA Income Tax Objection?
A Notice of Objection is a formal request asking the CRA to review a tax decision you believe is incorrect.
- 📄 Dispute tax assessments or reassessments
- ⚖ Request an independent internal review
- 🧾 Challenge penalties, interest, or income calculations
It is the required first step before you can take your case to court.
⏱ Deadlines You Must Know
- ⏳ You have 90 days from the date of your assessment to file an objection
- 📅 Late filing possible only with extension (within 1 year)
Missing this deadline may result in losing your right to dispute the assessment.
📝 How to File an Objection (Step-by-Step)
- Review your assessment carefully
- Gather supporting documents (receipts, records, explanations)
- Submit your objection:
- 💻 Online via CRA “My Account”
- 📄 By mail using Form T400A
- Explain clearly why CRA is wrong
The objection must include facts and legal reasoning—not just a statement of disagreement.
📂 What Happens After Filing?
Once submitted, your case is reviewed by the CRA Appeals Division:
- 👤 Assigned to an independent appeals officer
- 📨 You may be asked for more information
- 📊 Review can take months (or longer)
The CRA may:
- ✔ Confirm the original assessment
- ✏️ Adjust (reassess) the amount
- ❌ Cancel the assessment
If you still disagree, you can escalate the case to the Tax Court of Canada.
📊 Common Reasons for Objections
- Incorrect income calculation
- Denied deductions or credits
- Audit disagreements
- Penalty or interest disputes
Many objections arise from misunderstandings or missing documentation rather than actual errors in law.
💡 Pro Tips to Increase Your Chances
- Be detailed and structured in your explanation
- Attach all supporting evidence upfront
- Respond quickly to CRA requests
- Consider professional tax advice for complex cases
A well-prepared objection significantly improves your chances of success.
⚠️ Common Mistakes to Avoid
- ❌ Missing the 90-day deadline

- ❌ Writing vague or emotional arguments
- ❌ Ignoring CRA follow-up requests
📜 Legal Framework
The objection process is governed by the Income Tax Act and ensures taxpayers have the right to dispute decisions before going to court.
