You can find your notice of assessment or reassessment online in your CRA MyAccount, or by mail. When you receive your assessment, it’s important to compare it with your copy of your tax return, to see where any changes were made, if any.

Keep your notice of assessment with your tax documents for that year. If you need to consult key information about your tax return for that year, it’s likely that the assessment will be useful.

Your notice of assessment contains information about how much RRSP contribution room and TFSA contribution room you have available for the coming year. This can help you plan your contribution and investing strategy to either or both accounts. If you work with a financial advisor, they may ask you about your contribution room for these accounts. Bring your NOA with you or consult it before meeting with your advisor.

What if you disagree with your notice of assessment?

If you receive your notice of assessment, and you disagree with changes made to your return or account, you can contact the CRA to file an objection. Objections lead to a review of the assessment or determination. To file an objection:

  1. Contact the CRA – You’ll find the Canada Revenue Agency (CRA) phone number on your notice of assessment. You’ll need to address the miscommunication or mistake and provide any further information needed to clear things up. You can also use this online decision tree questionnaire provided by the CRA, to help you determine whether you should file an objection. Have your notice of assessment and any other CRA correspondence on hand.
  2. File an objection – If you’re not satisfied after speaking with the CRA, you can file an objection (T400A). This is a formal dispute. You have to give the reasons for the dispute and present the relevant facts and documents.
  3. Appeal to the Tax Court of Canada – If you disagree with the CRA’s ruling on your objection, you can appeal to the Tax Court of Canada.

Consider hiring a tax professional to help you with filing a notice of objection or appealing to the Tax Court of Canada.

Summary

You will be sent a notice of assessment after your tax return has been processed. It’s an important document that should be kept alongside all other tax documents for each tax filing year.
