Key takeaways
  • In the informal procedure, all parties may appear in person or be represented by counsel or an agent.
  • In the general procedure, an individual may appear in person or be represented by counsel.
  • Help matters most with deadlines, the more structured general procedure, settlement offers and further appeals.

If you disagree with a CRA assessment after the objection stage, going to the Tax Court of Canada can feel intimidating. Many people wonder whether they must hire a lawyer, or whether they can simply speak for themselves.

The short answer is that the rules allow individuals to appear on their own. Whether you should is a separate question that depends on the size and complexity of the dispute and the procedure you are in.

This article covers Canadian federal tax law, which applies in every province.

Can you appear on your own?

Yes, in the situations described here. Under the informal procedure, all parties may appear in person or be represented by counsel or an agent. Under the general procedure, Tax Court of Canada Act s. 17.1 provides that an individual may appear in person or be represented by counsel.

Whether other kinds of taxpayers, such as corporations, must be represented can differ, so confirm that point before you file if it applies to you.

Who can represent you

ProcedureWho may appear
Informal procedureThe party in person, or counsel or an agent
General procedureAn individual in person, or counsel

The word agent is significant. In the informal procedure, you are not limited to a lawyer; an agent may speak for you. In the general procedure, the provision refers to counsel.

Why the procedure you are in affects the answer

The informal procedure is designed to be more accessible. The Court is not bound by legal or technical rules of evidence, and your notice of appeal sets out reasons and facts in general terms. It is available where the amounts in issue are $25,000 or less, or a loss is $50,000 or less, and you elect it, or where only interest is in dispute.

The general procedure asks more of you. The Crown replies within 60 days, and facts you allege that are not denied in the reply are deemed admitted. Each party files a list of documents within thirty days after the pleadings close. Examinations for discovery require you to answer proper questions, correct earlier answers that were wrong or incomplete, and accept that the other side may read your discovery evidence into its case at the hearing. These steps are where self-represented people most often find the process demanding.

When professional help matters most

If your dispute is under the informal limits and the facts are simple, representing yourself may be realistic. Larger or more technical disputes are where advice tends to matter most.

What to do next

Frequently asked questions

Can I represent myself in the Tax Court of Canada?

Yes, if you are an individual. In the informal procedure parties may appear in person or be represented by counsel or an agent, and in the general procedure an individual may appear in person or be represented by counsel.

Can a non-lawyer represent me?

In the informal procedure, parties may be represented by counsel or an agent. For the general procedure the provision refers to counsel, so confirm who may act for you before relying on someone else.

Is the informal procedure easier to handle without a lawyer?

It is less technical: the Court is not bound by legal or technical rules of evidence, and the notice of appeal sets out reasons and facts in general terms. It is still a court process with deadlines, so many people get advice first.

Should I get help if the CRA's deadline has already passed?

It is wise to. An extension requires an application to the Tax Court within one year after the 90-day period, and you must meet specific tests. A lawyer can confirm whether your situation fits.
