Key takeaways
  • The Income Tax Act sets the Tax Court appeal as the step that follows a notice of objection that you have served.
  • If you missed the objection deadline, the fix is a separate application to the Minister, not a Tax Court appeal.
  • Some special situations, such as ecological gifts, follow their own appeal timelines.

You received a notice of assessment, disagreed with it, and let the objection stage slide. Now you are wondering whether you can go straight to the Tax Court of Canada and ask a judge to look at it.

The short answer is that the law is built around objecting first. This article explains how the steps fit together, what the exceptions look like, and what options may remain if you missed the objection deadline.

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

How the objection and appeal steps fit together

Under the Income Tax Act, a taxpayer may appeal to the Tax Court of Canada to have an assessment vacated or varied after serving a notice of objection and once the Minister has confirmed the assessment or reassessed. The appeal is therefore written as the second step, following the objection.

A notice of objection must be in writing and set out the reasons and all relevant facts. When the Minister receives it, the Minister must reconsider the assessment with all due dispatch, then vacate, confirm or vary it, or reassess, and notify you in writing. That written decision is what normally opens the door to the Tax Court.

The objection deadline

For individuals (other than trusts) and graduated rate estates, the objection deadline is the later of one year after the filing-due date or 90 days after the notice of assessment was sent. For others, it is 90 days.

There is a narrower rule where the Minister assesses to reflect certain matters already determined. In that case the objection must be made within 90 days, and the objection and appeal are limited to reasons that cannot reasonably be regarded as already dealt with.

Exceptions and special situations

Several situations work differently from the ordinary path. Whether one applies to you depends on the facts, so it is worth confirming with a lawyer or accountant.

If you missed the objection deadline

A late objection is handled differently from a late appeal. You first apply to the Minister (Chief of Appeals) under s. 166.1, within one year after the objection deadline. You must show that you were unable to act or had a bona fide intention to object, that granting the request is just and equitable, and that you applied as soon as circumstances permitted.

Do not confuse this with the Tax Court's power to extend the time to appeal. That power deals with a missed appeal period, and the application must be made within one year after the 90-day appeal period expires.

Penalties and interest have another route. The Minister may waive or cancel them under s. 220(3.1) on or before the day that is ten calendar years after the end of the taxation year. This is an administrative relief decision, not a Tax Court appeal. If a relief request is refused, a second administrative review is offered, and you can apply to the Federal Court for judicial review within 30 calendar days of receiving the decision.

What to do next

Frequently asked questions

Can I skip the objection and go straight to the Tax Court?

The Income Tax Act describes the appeal as following a notice of objection and the Minister's confirmation or reassessment. A few special situations, like ecological gifts, have their own timelines. A lawyer can confirm whether your case is one of them.

What if I never got a decision on my objection?

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.

I missed the objection deadline. Is it over?

Not necessarily. You can apply to the Minister (Chief of Appeals) for more time, within one year after the objection deadline. You must meet the stated tests, including that you applied as soon as circumstances permitted.

Can the Tax Court review a refused penalty relief request?

A refused relief request under s. 220(3.1) is not a Tax Court appeal. After the CRA's second review, you can apply to the Federal Court for judicial review within 30 calendar days of receiving the decision.
