- On receiving a notice of objection, the Minister must reconsider the assessment and notify you in writing.
- Your notice of objection is addressed to the Chief of Appeals and delivered or mailed to a CRA District Office or Taxation Centre.
- If you disagree with the result, you can appeal to the Tax Court of Canada.
If an auditor reassessed you, it is reasonable to doubt that another part of the same agency will look at your case fairly. Many people ask whether the appeals officer is truly separate from the auditor.
This article describes what the law and CRA guidance say about how an objection is handled, and what independent checks exist outside the CRA. It does not describe the CRA's internal reporting structure, which is something a lawyer can help you explore.
This article covers Canadian federal tax law, which applies in every province.
Where your objection goes
A notice of objection is served by addressing it to the Chief of Appeals at a CRA District Office or Taxation Centre and delivering or mailing it there. The CRA says the Appeals Intake Centre in Sudbury, Ontario receives mailed or faxed objections.
Filing through a secure portal such as My Account, My Business Account or Represent a Client gets the objection assigned to an appeals officer sooner than paper.
What the law requires on review
When the Minister receives a notice of objection, the Minister must reconsider the assessment and vacate, confirm, vary or reassess it, then tell you the result in writing. The reconsideration is a legal duty, not a courtesy.
The objection itself is your chance to put your case. It must set out the reasons and all relevant facts, and the CRA says to include copies of supporting documents. If you are a large corporation, your objection must instead reasonably describe each issue, state the relief sought for each issue and give the facts and reasons for each one.
If you held back information during the audit and give it only with your objection, the file may be sent back for a second review. That means new information may lead to the file returning for another look.
What an objection does not cover
- An auditor's proposal letter cannot be objected to.
- A statement of account cannot be objected to.
- An issue on which you waived the right of objection in writing cannot be objected to.
- Examples the CRA lists include RRSP or TFSA room statements, refund interest and nil assessments.
- A reassessment issued under the Taxpayer Relief provisions cannot itself be objected to.
If you are unsure whether what you received can be objected to, a lawyer or accountant can confirm. Objections filed late or before the notice was issued may be invalid.
The check outside the CRA: the Tax Court
The strongest assurance of fairness is that the CRA does not have the final word. If the CRA disagrees with your objection, it sends a Notice of Confirmation or a reassessment, and you can then appeal to the Tax Court within 90 days. You can also appeal once 90 days have passed since you served the objection with no decision.
The Tax Court has Informal and General procedures. Informal appeals have no filing fee, and General Procedure appeals have a fee based on the amount in dispute. After serving a notice of objection, you can appeal a resulting reassessment to the Tax Court without serving a new notice of objection. Once you appeal to the Tax Court, collection of the disputed amount is generally barred until the decision is mailed to you or you discontinue the appeal. This does not apply to some amounts, such as amounts that must be withheld and remitted, Part VIII amounts, s.281 amounts, certain s.116 tax, related penalties and interest, or cases CRA considers to be in jeopardy. A large corporation (taxable capital employed in Canada, with related corporations, over $10 million) or a taxpayer in certain tax shelter cases can also be required to pay one-half of the assessed amount within 90 days of the notice of assessment.
Practical steps if you are sceptical
- Meet the deadline, which for most individuals is the later of one year after the filing-due date and 90 days from the notice date.
- File through a secure portal if you can, since it reaches an appeals officer sooner.
- Give complete facts, reasons and documents.
- Quote your case number in all later correspondence.
- Keep the Tax Court deadline in mind if you disagree with the result.
Processing time varies by complexity. For objections resolved in August 2026, the average was 145 days for low complexity and 403 days for medium complexity. The CRA counts time within government control and excludes time you take to provide more information. A lawyer can advise on how best to present your case.
Frequently asked questions
Does my objection go to the auditor?
It is addressed to the Chief of Appeals at a CRA District Office or Taxation Centre. Mailed or faxed objections are received at the Appeals Intake Centre in Sudbury, Ontario.
Is the appeals officer's decision final?
No. If the CRA confirms or varies the assessment, you can appeal to the Tax Court within 90 days. Further appeals may follow, such as to the Federal Court of Appeal within 30 days of the Tax Court's final judgment, not counting July and August.
Can I object to the auditor's findings before a reassessment is issued?
No. You cannot object to an auditor's proposal letter. You can object to the notice of assessment or reassessment.
Do I have to pay while the objection is reviewed?
Generally, you do not have to pay disputed income tax until the objection review is complete. Interest keeps accruing unless you pay all or part of the amount.
