CRA Informant / Whistleblower Audit — Montreal CPA Firm Near You: Manage Tip Exposure

A CRA Informant or Whistleblower Audit is triggered when the Canada Revenue Agency (CRA) or Revenue Québec receives a confidential tip about alleged tax evasion, unreported income, or misrepresented deductions. These audits originate from the CRA’s Offshore Tax Informant Program (OTIP) or domestic leads, including employee, competitor, or ex-partner disclosures. Mackisen CPA Montreal provides full professional representation, forensic documentation, and risk-control strategies to manage tip-based audits discreetly and effectively.
Legal Foundation
Law: Income Tax Act s.239 (false or misleading statements); Excise Tax Act s.327; Tax Administration Act (Québec) s.105 (confidential informants).
Jurisprudence: R. v. Jarvis (2002 SCC) — establishes that taxpayer rights under the Charter of Rights and Freedoms apply once an investigation becomes penal in nature.
Why You Need a CPA for a Whistleblower or Informant Audit
Tip-based audits are not random—they are targeted. CRA and ARQ receive thousands of tips yearly, but only pursue those supported by evidence. Once selected, your case is investigated with higher scrutiny than standard audits. A CPA ensures your records, correspondence, and responses are complete, consistent, and legally protected.
Mackisen CPA Montreal immediately reviews the nature of the allegation, reconstructs the facts, and prepares documentary proof that neutralizes risk before CRA or ARQ escalates the matter.
Learning insight: CRA investigates claims—but prosecutes evidence gaps. A CPA fills those gaps before they’re used against you.
