If the CRA Appeals division rejects your Notice of Objection, they will mail you a “Notice of Confirmation.” You generally have only 90 days from the date on this notice to escalate your dispute by filing an appeal with the Tax Court of Canada. Missing this deadline usually means the tax debt becomes final and legally binding.
Dealing with the Canada Revenue Agency (CRA) is daunting, but receiving a rejection after months of waiting is incredibly frustrating. Whether you are an individual in Montreal fighting disallowed expenses, or a small business owner in Edmonton disputing a GST/HST audit, the Notice of Objection is meant to be your chance for an internal review. However, the CRA Appeals division frequently sides with the original auditor.
When your objection is rejected, the CRA issues a Notice of Confirmation, legally stating that they consider their original tax assessment to be perfectly correct. This is not the end of the road. Your next step removes the dispute from the hands of the CRA entirely and places it into the federal judicial system. You have the right to appeal to the Tax Court of Canada, an independent court dedicated to resolving disputes between taxpayers and the government.
Step-by-Step Process: Appealing to the Tax Court of Canada
Escalating to the Tax Court requires strict adherence to legal rules and deadlines. You are no longer dealing with CRA agents; you are facing Department of Justice (DOJ) lawyers. Here is how you take your case to court.
Step 1: Track Your 90-Day Deadline
The moment you receive the Notice of Confirmation, mark your calendar. Under the Income Tax Act, you have exactly 90 days from the date printed on the notice (not the date you received it) to file your Notice of Appeal with the Tax Court of Canada. If you miss this window, applying for an extension is extremely difficult and rarely granted.
Step 2: Choose the Correct Court Procedure
The Tax Court offers two tracks: the Informal Procedure and the General Procedure. If your disputed federal tax amount is under $25,000 CAD per tax year, you can choose the Informal Procedure, which is faster and allows you to represent yourself or use an accountant. If the amount exceeds $25,000 CAD, or if the matter is highly complex, you must use the General Procedure, which functions like a formal trial.
Step 3: Draft and File the Notice of Appeal
Your Notice of Appeal must outline the material facts of your case, the specific sections of the tax law you are relying on, and the reasons the CRA’s assessment is incorrect. This document is filed directly with the Tax Court registry. Once filed, the DOJ will formally reply to your appeal with a “Reply to the Notice of Appeal.”
Step 4: Engage in Settlement Discussions
Most Tax Court cases never actually go to trial. Once the appeal is filed, a DOJ lawyer takes over the file from the CRA. These lawyers evaluate “litigation risk.” If your tax lawyer presents a strong case with solid evidence, the DOJ may offer a settlement out of court to avoid wasting judicial resources.
Informal Procedure vs. General Procedure
| Feature | Informal Procedure | General Procedure |
|---|---|---|
| Financial Limit | Under $25,000 CAD (Federal tax per year). | Over $25,000 CAD (Or by taxpayer choice). |
| Representation | Self, CPA, or Lawyer. | Corporations must have a Lawyer. Individuals can self-represent but a Lawyer is highly advised. |
| Timeline to Trial | Usually 6 to 12 months. | Usually 1 to 3 years. |
How Much Does Tax Court Cost in Canada?
Taking the government to court involves filing fees and legal representation costs, which must be weighed against your total tax debt.
- Court Filing Fees: The Informal Procedure has no filing fee. For the General Procedure, filing fees range from $250 to $550 CAD depending on the amount in dispute.
- Tax Lawyer Fees: For an Informal Procedure, a lawyer might charge $3,000 to $7,000 CAD. A full General Procedure trial can easily cost $15,000 to $30,000+ CAD.
- Cost Awards: In the General Procedure, if you win, the judge may order the CRA to pay a portion of your legal fees. If you lose, you may have to pay a portion of the government’s legal costs.
How Long Does the Process Take?
The judicial system operates on its own schedule. By May 2026, if you file under the Informal Procedure, expect your hearing to occur within 8 to 12 months. The General Procedure involves formal “discovery” phases where lawyers exchange evidence, pushing the trial date to anywhere from 1.5 to 3 years after filing. During this time, the CRA is generally restricted from taking collection action on standard income tax disputes.
Frequently Asked Questions (FAQ)
Do I have to pay the CRA while waiting for Tax Court?
Generally, for personal and corporate income tax disputes, the CRA cannot seize your bank accounts or garnish your wages while an active appeal is before the Tax Court. However, this protection does not fully apply to GST/HST disputes or payroll remittance audits.
Can the CRA collections agency call me after I file an appeal?
Once your Notice of Appeal is officially filed and acknowledged by the court, CRA collections officers must legally pause their enforcement actions for standard income tax. If they call, simply provide your Tax Court file number.
Can I submit new evidence to the Tax Court?
Yes. The Tax Court conducts a “trial de novo,” meaning they look at the case fresh. You can present new documents, new witnesses, and new legal arguments that the original CRA auditor or Appeals officer never saw.
What happens if I miss the 90-day deadline?
If you miss the 90-day window, you can apply to the Tax Court for an extension of time within the following 12 months. However, you must prove you had a strictly valid reason for the delay (like severe hospitalization) and that you always intended to appeal.
