🚩 Common CRA Audit Red Flags
- Large or unusual deductions — claiming excessive medical, business, or charitable deductions
- Unreported income — CRA gets tax slips (T4, T5, T4A) directly from employers and banks
- Discrepancies between reported income and lifestyle — lavish spending without matching income
- Home office claims without justification
- Self-employment income inconsistencies — especially in cash-heavy industries (e.g. contractors, hairstylists)
- Rental income not reported — including Airbnb and secondary suite revenue
- Frequent business losses — if your business reports losses for several years, CRA may reclassify it as a hobby
✅ Best Practices to Avoid a CRA Audit
- Report all income including tips, freelance earnings, and foreign income
- Keep detailed records — invoices, receipts, mileage logs, and bank statements
- Use CRA-certified tax software and file electronically with NETFILE
- Hire a licensed tax preparer if your return is complex
- Justify all deductions and keep supporting documents for at least six years
- Separate personal and business expenses
- Review tax slips (T4, T5, T5013, etc.) for accuracy before filing
📋 What Happens During a CRA Audit?
If the CRA selects you for an audit, they will contact you by mail or phone. You may be required to:
- Submit receipts or additional documentation
- Meet with an auditor in person or provide records electronically
- Clarify income or deductions claimed
Failure to comply can result in reassessments, penalties, and even prosecution for tax evasion in severe cases.
🛡️ How to Respond If Audited
- Stay calm and cooperative — audits aren’t always adversarial
- Provide requested documents promptly
- Work with a tax professional to handle complex inquiries
- Request an extension if more time is needed
- Appeal the CRA’s decision if you disagree with the outcome
