Summary
- A Notice of Assessment (NOA) is a tax form issued to taxpayers by the Canada Revenue Agency after processing income tax returns.
- An NOA includes a summary of income taxes to be paid or refunded during the current tax year.
- The NOA also summarizes the Registered Retirement Savings Plan contributions during the tax year and any unused contributions.
Understanding the Notice of Assessment
The Notice of Assessment is calculated based on the tax returns submitted by a taxpayer. It is a two-page document, and it indicates the name of the taxpayer, insurance number, the tax year, and the tax center.
If a taxpayer finds errors in the NOA, they are allowed to submit an adjustment request, highlighting the errors to be fixed. The Canada Revenue Agency allows up to 90 days from the date the NOA is issued to appeal the information if there is information they do not agree with.
For example, if a taxpayer expects to receive tax refunds of $8,000, but the NOA indicates that the taxpayer owes the CRA $3,000, a taxpayer can appeal the error within 90 days. When appealing, the taxpayer is required to attach any supporting documentation that explains their objection to the assessed income tax.
After submitting an appeal, the taxpayer is not required to pay the amount in dispute until the review is completed. Any appeals after the 90 days have elapsed are not considered, and the taxpayer information will be sent to collections.
Registered Retirement Savings Plan (RRSP)
One of the important items included in the Notice of Assessment is the Registered Retirement Savings Plan (RRSP). The section lists the RRSP contributions that a taxpayer made during the tax year, any unused contributions during the tax year, and the contribution limits for the following tax year. The CRA uses the information included in the tax returns for the relevant tax year to determine the maximum contributions that individuals can contribute towards their RRSP for the following year.
Taxpayers can claim the RRSP contributions as a deduction from the taxable incomeTaxable IncomeTaxable income refers to any individual's or business’ compensation that is used to determine tax liability. The total income amount or gross income is used as the basis to calculate how much the individual or organization owes the government for the specific tax period.. The taxpayer is not required to claim the deductions during the tax year, and the deductions are carried forward to the following tax year if they expect to receive increased incomes. It allows them to claim a bigger deduction from the tax bill for the following year.
However, if a taxpayer accumulates unused contributions where previous contributions and the current year’s contributions exceed the RRSP deduction limit, a taxpayer may be penalized by the CRA. The taxpayer will be required to pay a penalty at the rate of 1% per month for the excess RRSP contribution amount.
How to Get a Notice of Assessment
After submitting tax returns for the year, a taxpayer can expect to receive the Notice of Assessment in two to eight weeks, depending on whether they submitted the tax return electronically or through paper-based returns. A taxpayer can receive the NOA in the following two ways:
1. Snail mail
If a person has not registered for online mail, the NOA is sent through regular mail.
2. Online mail service (by CRA)
Taxpayers can register to receive the NOA through online mail when filing tax returns electronically. The option is enabled under the CRA “My Account” service. Taxpayers can also check their return status and the NOA under the “My Account” tab. If the NOA is available, you can download the statement as a PDF.
CRA Audits

It includes whatever base salary an employee receives, along with other types of payment that accrue during the course of their work, which of taxpayers, especially when the agency suspects that a taxpayer has under-reported the annual income or over-reported the annual expenses to reduce the tax liability.
The tax audit involves cross-examination of all revenues and expenses incurred during the tax year by the taxpayer, and sometimes the spouse. A tax audit may also be conducted randomly for a select number of taxpayers or members of a tax group.
Once an auditor has sent a request for a tax audit, a taxpayer is required to furnish the auditor with all the requested information, such as evidence of expenses incurred during the year, financial statements for the current and previous tax years, etc.
For tax purposes, taxpayers are required to maintain a record of the tax records and relevant documents for the past six years, including the current year. If the outcome of the audit reveals discrepancies in the incomes and expenses reported, the CRA may order a reassessment of the current and previous years’ income taxes.
