What is a CRA Notice of Objection? 


A notice of objection is a dispute mechanism a taxpayer has to contest an assessment, reassessment, determination, or redetermination.

There are three important points to understand when filing a notice of objection:


  • How long you have to file a Notice of Objection?
  • How do you file a Notice of Objection?
  • What should you include in your Notice of Objection?


You have 90 days from the date on the assessment or reassessment notice received from the CRA to file a notice of objection. However, if you miss this window, you are still able to request an extension of time to file. This extension must be filed within one year of missing the 90-day window, or else you are no longer able to file a notice of objection.

If you file an extension, you must include the reasons why you failed to file your notice of objection on time.

If you are within the 90-day window to file your notice of objection, you can file your objection online through CRA’s My Account, or My Business Account. If you have an authorized representative, like an accountant or a tax lawyer, they can file the objection on your behalf. However, if you miss the 90-day window, you, or your authorized representative, must file your objection by mail.

It is important to lay out as much relevant information as possible when filing a Notice of Objection. This can include why the assessment is wrong, and any argument you have to support your belief. Because every tax dispute is different, it is recommended that you seek the advice of an experienced professional before dealing with the CRA.
