01. Industry Outliers
The CRA compares your profit margins against the average for your North American Industry Classification System (NAICS) code. Significant deviations without documented justification trigger an immediate manual review.

Risk of Targeted Review
Statistics indicate that one-third of small to medium enterprises face some form of CRA verification within a five-year cycle. Selection is rarely random; it is driven by automated risk-assessment algorithms that flag discrepancies between reported income and industry norms.
Refer to our CRA Compliance Manual to calibrate your internal reporting systems against these automated triggers.
Technical Triggers
02. Payroll Discrepancies
Inconsistencies between T4 summaries and corporate tax returns regarding labor costs are high-priority flags. Review the Employer Payroll Tax Guide for reconciliation steps.
03. Recurring Losses
Reporting business losses for three or more consecutive years while maintaining lifestyle expenses suggests unreported income or a lack of "reasonable expectation of profit," prompting a "Personal Living Expenses" audit.
Comparative Analysis Protocol
To prevent selection, you must perform an internal audit using the same criteria as the CRA’s Business Intelligence unit. This involves calculating your gross margin percentage and comparing it to the median values in your specific sector.
⚠️ Important: Professional expenses such as travel, promotion, and vehicle use are scrutinized if they exceed 15% of gross revenue in service-based industries.
If your figures fall outside the standard deviation, prepare a "Narrative of Variance." This document should explain the economic reasons for the anomaly—such as market entry costs or supply chain disruptions—before the CRA requests it.
Compliance Maintenance Steps
- 01
Digitize Original Source Documents
Scan and categorize all receipts, invoices, and bank statements. The CRA accepts digital copies if they are clear, complete, and stored in a systematic manner that allows for easy retrieval.
- 02
Maintain a 6-Year Archive
Keep all records for six years from the end of the last tax year they relate to. Failure to produce documents during an audit results in the immediate disallowance of the associated expense.
- 03
Perform Quarterly Reconciliations
Cross-reference your internal ledger with GST/HST filings and payroll accounts every 90 days. Early detection of errors allows for correction via the Voluntary Disclosures Program.
