Frequently Asked Questions

What percentage of Canadians get audited by CRA each year?

Less than 1% of individual T1 filers are selected for a full audit annually — the rate is approximately 0.4%. However, CRA conducts over 900,000 total compliance interventions per year when desk reviews, matching programs, and targeted reviews are included. Self-employed individuals face a significantly higher risk, estimated at 3–4%.

How far back can CRA audit you in Canada?

CRA can normally reassess individual returns within 3 years of the date of original assessment (the "normal reassessment period"). However, this extends to 6 years for non-arm's-length transactions or misrepresentation. There is no time limit if CRA can establish fraud or gross negligence, making accurate record-keeping essential for all taxpayers.

What are the biggest audit red flags for Canadian taxpayers?

CRA's risk-scoring algorithms flag returns with large deductions relative to reported income, consistent self-employment losses, significant business-use vehicle or home office claims, rental income discrepancies, and unreported foreign assets. High-income individuals, those with offshore accounts, and taxpayers in cash-heavy industries face elevated scrutiny.

What happens if CRA audits you and finds unreported income?

If CRA determines income was omitted, they will reassess to include it plus interest from the original due date. If the omission is found to be negligent, a 50% gross negligence penalty under ITA s.163(2) applies. Deliberate evasion can trigger criminal prosecution. Taxpayers who come forward voluntarily through the Voluntary Disclosures Program (VDP) may avoid penalties and prosecution.

Can you dispute a CRA audit result?

Yes. If you disagree with a reassessment, you have 90 days from the date on the notice to file a formal Notice of Objection. An independent CRA Appeals Officer reviews the file. If unresolved, you can appeal to the Tax Court of Canada. Approximately 30% of reassessments are reduced or reversed at the objection or appeal stage.
