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) receives a tip — often from a former employee, ex-partner, or competitor — alleging undeclared income, offshore accounts, or aggressive deductions.
These audits can create stress and reputational risk even when the allegations are false. Mackisen CPA Montreal provides confidential representation and defense, ensuring your file is handled with professionalism, evidence, and precision — not speculation.

Legal Foundation

Law: Income Tax Act s.231.1 (audit powers), s.239 (false statements and penalties), and CRA’s Offshore Tax Informant Program (OTIP) (2014).
Jurisprudence: R. v. Jarvis (2002 SCC) — clarified that once CRA’s purpose shifts from audit to investigation, the taxpayer is entitled to full Charter protections, including the right to silence and legal counsel.

Learning insight: CRA trusts whistleblowers — until your CPA shows the facts. Mackisen CPA replaces assumptions with verified documentation.

Why CRA Acts on Informant Tips

CRA receives thousands of informant submissions yearly, but only credible allegations supported by evidence are pursued. Common triggers include:

• Anonymous or named tips about hidden income or false invoices.

• Former employees revealing internal records.

• Ex-spouses sharing tax or lifestyle discrepancies.

• Competitors reporting cash-based or unregistered operations.

• Whistleblower reports under the Offshore Tax Informant Program (OTIP) involving foreign income over $100,000.

Learning insight: Whistleblowers only need to raise suspicion — your CPA must close it with facts.

The CRA Whistleblower Audit Process

1. Tip Evaluation: CRA screens the tip for credibility and relevance.

2. Preliminary Review: CRA cross-references allegations with filings, banking, and third-party data.

3. Audit Notice: If inconsistencies appear, CRA issues an audit letter requesting documentation.

4. Field Review: CRA may visit business premises or contact third parties for confirmation.

5. Audit Outcome: CRA may accept your evidence, reassess income, or escalate to its Criminal Investigations Division (CID).

Learning insight: CRA doesn’t need proof to open an audit — it needs proof to close one. Mackisen CPA delivers that proof.
