Key takeaways
  • If the Minister has not notified you of a decision, you may appeal once 90 days have passed after service of your notice of objection.
  • You do not need to wait for CRA Appeals to decide before going to the Tax Court.
  • If you miss an appeal deadline, an extension is possible but strictly limited.

You filed a notice of objection and months have gone by with no answer. It is natural to wonder whether you must keep waiting for the CRA to finish its review.

In many cases you do not. The Income Tax Act gives you a route to the Tax Court of Canada even without a decision, and this article explains how it works and what to watch for.

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

The usual route and the no-answer route

Normally, after you serve a notice of objection, you may appeal to the Tax Court of Canada to have the assessment vacated or varied once the Minister has confirmed the assessment or reassessed. The Minister must reconsider the assessment with all due dispatch and then notify you in writing.

If the Minister has not notified you of a decision, you may appeal once 90 days have elapsed after service of the notice of objection. You need not wait for CRA Appeals to decide. For GST/HST objections the wait is 180 days.

The deadline when the CRA does answer

If the CRA does respond, the clock changes. The deadline is 90 days from the day the notice was sent saying the Minister confirmed the assessment or reassessed. The CRA says the Court must receive your notice of appeal within that 90 days.

The CRA lists ways to file: delivery, mail, fax or the Court's electronic filing. Because the Court must receive the notice in time, leave room for delivery.

Exceptions to be aware of

If you miss the deadline

You may apply to the Tax Court for an order extending the time to appeal, and the Court may impose terms it considers just. The application sets out the reasons for the delay and is filed with three copies of the application and three copies of the notice of appeal.

No extension can be ordered unless the application is made within one year after the 90-day period expires. You must also show that within the 90 days you were unable to act or instruct someone to act, or had a genuine intention to appeal, that it is just and equitable to grant the application, that you applied as soon as circumstances permitted, and that there are reasonable grounds for the appeal.

A late notice of objection is different. You first apply to the Minister (Chief of Appeals) within one year after the objection deadline.

What to do next

Frequently asked questions

Can I go to the Tax Court if the CRA has not replied to my objection?

Yes. If the Minister has not notified you of a decision, you may appeal once 90 days have elapsed after service of your notice of objection. You do not have to wait for CRA Appeals to decide.

Is the waiting period the same for GST/HST?

No. For GST/HST objections the CRA states the wait is 180 days.

What if the CRA answers after I have already appealed?

That depends on the facts, so it is worth asking a lawyer. With your written consent, the Minister may reassess at any time to dispose of an appeal.

Can I still appeal if I missed the 90 days?

Possibly. You can apply to the Tax Court for an extension, but only within one year after the 90-day period expires, and you must meet the statutory conditions.
