Learn the step-by-step process to challenge a CRA decision and protect your rights.
Receiving a decision from the Canada Revenue Agency (CRA) that you disagree with can be overwhelming. Whether it’s a reassessment, denied deduction, or penalty, you have the legal right to challenge it through a structured process.
Step 1: Review the CRA Notice Carefully
Start by examining your Notice of Assessment or Reassessment. Pay close attention to what changes were made, why they were made, and any additional taxes or penalties.
Step 2: File a Notice of Objection
If you disagree with the CRA’s determination, you must file a Notice of Objection within 90 days. This can be done online through CRA My Account or by submitting Form T400A.
Step 3: Provide Supporting Documents
Supporting documentation should include receipts, contracts, and financial records. A well-supported objection improves your chances of success.
Step 4: CRA Appeals Review
The Appeals Division will independently review your case and may request additional information before making a decision.
Step 5: Appeal to Tax Court
If you still disagree, you can appeal to the Tax Court of Canada within 90 days of the CRA’s decision.
