Understanding Your Notice of Assessment (And What to Do With It)

What the Notice of Assessment Includes

Your NOA contains several important pieces of information that summarize how the CRA has reviewed your tax return. Key elements include:

• Assessment summary: Shows the total income the CRA used to calculate your tax, the tax payable, and the final balance — an amount you owe, a refund, or a zero balance.
• Changes to your return: If the CRA made any adjustments, the NOA will detail these changes and explain differences in tax owing or refund.
• Instalment requirements: If required to pay tax instalments for the current year, the NOA provides amounts or thresholds.
• Carryforward amounts: Lists unused credits or deductions like tuition credits, capital losses, and RRSP contribution room that can be applied to future years.
• Credits and benefits: Updates on eligibility for benefits such as Canada Child Benefit (CCB) or GST/HST credit, which may be affected by your assessed income.
• Reassessment timeframe and objection rights: Provides the period for which the CRA can reassess your return (usually three years) and instructions for disputing assessments.
• Instalment due dates and interest: If you owe money, the NOA states payment due dates and explains interest calculations on overdue amounts.

How to Read the Key Sections of Your NOA

To ensure your tax affairs are in order, carefully review the following areas on your NOA:

• Personal and account details: Verify your name, address, and the partial social insurance number to ensure the information is accurate.
• Income and deductions: Compare the CRA’s reported income and deductions with your original filed return. Pay attention to any line-item adjustments.
• Balance owing or refund: Note the final figure. If you owe tax, the NOA will provide the due date and payment options.
• RRSP deduction limit and contribution room: Use this to plan future retirement savings and avoid penalties for over-contributions.
• Carryforward amounts: Record these amounts carefully, as they can reduce your tax liability in coming years.
• Instalment reminders: If instalments are required, note the amounts and payment deadlines to avoid interest charges.

Common Reasons Why the CRA Adjusts Your Return

Sometimes, the CRA makes changes to your return which are reflected in the NOA. Typical reasons include:

• Missing or mismatched slips: Employer or payer T slips (like T4, T5) may not match the figures you reported.
• Mathematical or transcription errors: Simple calculation mistakes or data entry errors can trigger corrections.
• Disallowed expenses: Self-employed individuals or businesses may have expenses disallowed if not properly documented or outside allowable categories.
• Unclaimed or misclaimed credits: Credits may be adjusted if eligibility is unclear without proper slips or documentation.
• Late or amended third-party information: Corrected slips submitted after you file can prompt reassessment.

What to Do When You Receive Your NOA

Receiving your NOA is an important moment in your tax cycle. To make the most of it, consider these steps:

• Compare the NOA to your filed return: Make sure the CRA’s assessment aligns with your submitted figures, particularly income, deductions, credits, and tax calculations.
• Keep it with your tax records: Store your NOA and related documents safely for at least six years in case the CRA requests proof later.
• Pay any balance owing or arrange payment: Pay on or before the due date to avoid penalties and interest. Options include online banking, CRA’s My Payment service, pre-authorized debit, or paying at your bank.
• If you cannot pay in full: Contact the CRA to discuss a payment arrangement. Be ready to provide financial details to support your situation.
• Review instalment obligations: If instalments are required, understand the schedule and amounts to avoid interest and penalties.
• File a notice of objection if you disagree: If you believe the CRA made errors, you can file a formal objection. The NOA explains timeframes and procedures. Consider obtaining professional advice before doing so.
• Use carryforward amounts in future planning: Plan ahead using available RRSP contribution room, tuition credits, or capital losses to optimize your next tax return.
• Check for benefits changes: Changes in your assessed income can affect benefits like the Canada Child Benefit or provincial programs. Report changes as required.

When to Contact a Tax Professional

While many taxpayers can handle their NOA independently, certain situations benefit from expert advice:

• Complex adjustments: Significant changes in business income, capital gains, or deductions may require professional analysis and guidance.
• Objections and appeals: Preparing a clear, well-documented objection is often easier and more effective with professional support.
• Payment arrangements: Professionals can help negotiate plans or relief applications with the CRA and prepare necessary documentation.
• Long-term tax planning: Use NOA details such as RRSP room and carryforwards to strategize for retirement, tax deferral, or corporate structuring.

Practical Tips to Avoid NOA Surprises

• File accurate, complete returns by reconciling slips and claims before submission.
• Keep organized documentation like receipts and slips for at least six years.
• Use the CRA My Account portal to access your NOA and other tax information electronically and promptly.
• Consider a professional review for business or complex returns to minimize reassessment risks.

Final Checklist After Receiving Your NOA

• Verify personal information is correct.
• Confirm assessed amounts match your records.
• Note balance owing or refund and take appropriate payment actions.
• Record RRSP contribution room and carryforward amounts for future planning.
• Decide whether to accept the assessment or file an objection timely.
• Store your NOA and supporting documents securely for six years.
