Understanding Your Notice of Reassessment: A Guide for Taxpayers

Navigate the CRA's Reassessment Process with Confidence: Insights for Individuals and Businesses

Navigating the twists and turns of a Notice of Reassessment (NoR) from the Canada Revenue Agency (CRA) can seem like a daunting journey. Whether you're an individual taxpayer scratching your head over the numbers or a business trying to make sense of the revised figures, understanding your NoR is pivotal. In this guide, we'll walk you through the labyrinth, decoding each section of the reassessment notice, exploring why you might have received one, what it could mean for your finances, and how you can respond effectively.

Decoding Your Notice of Reassessment

Understanding the Components

Account Summary: At first glance, the account summary is your reassessment at a glance. It reflects the outcome of your tax return assessment, showing any changes in your balance, be it owing or refundable. It's essentially a snapshot of where you stand with the CRA post-assessment.

Tax Assessment Summary: This section dives deeper into the numbers. It outlines your taxable income, the taxes you've paid, and the credits you're entitled to. It's the nitty-gritty of your tax situation, presenting a line-by-line breakdown of your assessed tax return.

Explanation of Changes: Here's where the CRA sheds light on the adjustments made. Whether it's a discrepancy in your reported income or an error in your deductions, this section provides clarity on the modifications and their reasons.

Other Important Information: Occasionally, you might find additional notes or statements in your reassessment, such as an RRSP deduction limit statement. Understanding these can offer insights into future tax planning and compliance.

Why Did I Receive a Reassessment?

Receiving a NoR can trigger a flurry of questions. Common reasons include:

  • Data Mismatches: Perhaps the income reported doesn't match the CRA's records or third-party information (like T4 slips).

  • Miscalculated Deductions: Errors in claiming deductions or credits can prompt a second look.

  • CRA Audits: Sometimes, a reassessment follows a review or audit by the CRA, which could uncover discrepancies in your tax return.

It's crucial to remember that a reassessment isn't inherently negative. Often, it's the result of minor errors or misunderstandings that can be rectified.

The Financial Implications

What does this reassessment mean for your wallet? You might find yourself owing additional taxes or, conversely, entitled to a larger refund than initially calculated. It's vital to understand the reassessment's impact on your financial situation, including how it affects your future tax planning and compliance.

Responding to Your Notice of Reassessment

Agreeing with the Reassessment: If you find the CRA's reassessment to be accurate, your next steps may involve adjusting your financial records accordingly and settling any outstanding amounts owed.

Disagreeing with the Reassessment: Should you believe the reassessment to be incorrect, the CRA offers a formal objection process. You have the right to dispute the findings by filing an objection, typically within 90 days from the date of the reassessment notice. This process requires a detailed explanation of your disagreement, supported by relevant documents and figures.

Seeking Professional Help: Navigating a reassessment, especially if you're disputing it, can be complex. Engaging with a tax professional or a lawyer specializing in tax law can provide invaluable guidance, ensuring your objection is as robust and effective as possible.

Preventing Future Reassessments: Accuracy is key in tax filings. Ensuring your income is accurately reported and deductions correctly claimed can help mitigate the likelihood of future reassessments. Keeping thorough and organized financial records can also aid in this endeavour.


Can a notice of reassessment lead to an audit?

While a reassessment itself is not an audit, it could indicate that the CRA has questions about your tax return. It's not a given, but maintaining accurate and comprehensive records is your best defence.

How long do I have to respond to a reassessment?

Typically, you have 90 days from the issuance of the reassessment to file an objection if you disagree with the CRA's findings.

Where can I find professional help for dealing with a reassessment?

Tax professionals, accountants, and lawyers specializing in tax law can offer guidance and support in responding to a reassessment.


Understanding your Notice of Reassessment is crucial for both individual taxpayers and businesses. It's not just about interpreting the numbers but grasping the implications behind them and knowing how to respond effectively.
