No, your tax return is different from your notice of assessment. Your tax return is known as your income tax and benefit return, and it reports what you have earned as income and any deductions you have claimed to the Canada Revenue Agency. On the other hand, your notice of assessment is a document you receive from the CRA after submitting your tax return. Your notice of assessment shows the details on what you owe or will receive as a refund, information about penalties (if any), interest rates on amounts owing, and any changes that the Canada Revenue Agency makes to your tax return.
