A Notice of Assessment or Notice of Reassessment from the Canada Revenue Agency (CRA) or Revenu Québec is an official statement of the government’s calculation of your tax return, refund, balance owing, tax credits, deductions, reported income, instalments, or other tax amounts. It can be issued after an individual, self-employed person, landlord, corporation, trust, partnership, or business files a tax return, after a review or audit, or when the tax authority changes an amount originally reported.
Every notice should be reviewed carefully—even when it shows no immediate balance owing. A change may affect your personal income tax, corporate income tax, GST/HST, QST, payroll deductions, refundable tax credits, loss carryforwards, RRSP contribution room, instalment requirements, or future tax filings.
You may need a professional review if a notice differs from the return filed, denies an expense, tax credit, deduction, input tax credit, loss, or refund; adds income; changes a GST/HST or QST calculation; assesses interest or penalties; or requests payment that you do not understand. Expert Fiscaliste can compare the assessment or reassessment with your filed return and supporting documents, explain the reason for the adjustment, and help determine whether a correction, response, payment arrangement, or formal objection should be considered.
Important Deadlines
Do not delay after receiving an assessment, reassessment, review letter, demand for payment, or request for documentation. The deadline to protect your rights can be short.
For most CRA income-tax matters, corporations generally have 90 days from the date of the notice to file a Notice of Objection. Individuals—including employees, retirees, self-employed taxpayers, landlords, and many other personal taxpayers—and graduated rate estates generally have until the later of:
- 90 days after the date shown on the notice of assessment or reassessment; or
- One year after the filing deadline for the tax return in question. canada
For Revenu Québec, the standard objection deadline is generally 90 days from the date of the notice of assessment or notice of determination. In certain situations, an individual or testamentary trust may have a longer time limit, up to one year after the applicable return filing deadline, where that later date applies. revenuquebec
An objection is a formal process. A telephone call, informal discussion, or request for an explanation does not necessarily stop the objection deadline or preserve your right to contest the assessment. Contact Expert Fiscaliste as soon as possible after receiving any CRA or Revenu Québec notice so that we can review the matter, identify the applicable deadline, gather the necessary records, and help you take the appropriate next step.
