CRA Criminal Investigation (CID) Audit — Montreal CPA Firm Near You: Prevent Prosecution

A CRA Criminal Investigation Division (CID) Audit is the most serious level of tax enforcement in Canada. It occurs when the Canada Revenue Agency suspects deliberate fraud, falsification of records, or willful non-disclosure of income.
Unlike a regular tax audit, CID investigations are conducted jointly with the Department of Justice and often involve the RCMP or Revenu Québec’s penal division.
Mackisen CPA Montreal provides immediate and discreet defense strategies, ensuring your rights are protected, your records are managed properly, and your business stays operational throughout the process.
Legal Foundation
Law: Income Tax Act s. 239 (offences and penalties); Criminal Code s. 380 (fraud); Excise Tax Act s. 325 (false statements and tax evasion).
Jurisprudence: R. v. Jarvis (2002 SCC) — established the distinction between an “audit” (administrative) and a “criminal investigation” (penal). Once the CRA’s dominant purpose is prosecution, Charter rights apply.
Learning insight: Once CRA CID gets involved, it’s no longer about tax—it’s about criminal law. Every word, email, and document becomes evidence
Why CRA Launches Criminal Investigations
CRA’s Criminal Investigations Division intervenes when regular audit findings show intentional wrongdoing. Common triggers include:
Falsified or destroyed invoices and ledgers.
Double books or parallel POS systems (“zapper” software).
False refund claims or tax-shelter schemes.
Unreported cash income across multiple years.
Anonymous tips, whistleblower submissions, or competitor complaints.
Involvement in organized cash-economy or money-laundering networks.
Learning insight: CRA doesn’t “accuse first”—it builds evidence for months before you even know you’re under investigation. Mackisen CPA stops that evidence from being misunderstood.
The CRA CID Process
Preliminary Intelligence Gathering: CRA reviews prior audits, banking data, and third-party information.
Search Warrant Stage: CRA, with RCMP or ARQ assistance, may execute warrants to seize computers, ledgers, or financial data.
Formal Investigation: Evidence is analyzed, often with forensic accountants.
Prosecutorial Referral: Files are referred to the Public Prosecution Service of Canada (PPSC) if charges are recommended.
Resolution or Prosecution: CRA may offer a disclosure opportunity or proceed to criminal court.
Learning insight: CID investigations are designed to build a story—Mackisen CPA ensures your financial narrative is told accurately, not incriminatingly.
Mackisen CPA Montreal’s Criminal Audit Defense Strategy
Immediate Legal Shield: We coordinate with tax lawyers to assert Charter rights from day one.
Evidence Control: Review all CRA document requests to prevent over-disclosure or self-incrimination.
Forensic Reconstruction: Rebuild accounting ledgers to align intent with compliance, not concealment.
Voluntary Disclosure Evaluation: Assess whether a proactive filing under CRA’s VDP can neutralize prosecution.
Negotiation and Settlement: Present mitigating factors to prevent charges or minimize penalties.
Learning insight: Every CID case is a story of interpretation—Mackisen CPA ensures yours reads as correction, not crime.
Common Offenses Investigated by CRA CID
Filing false or misleading returns.
Claiming fictitious expenses or dependents.
Submitting fake invoices or refund claims.
Concealing offshore income or accounts.
Obstruction of audit by withholding documents.
Each carries severe penalties, including fines up to 200% of tax evaded and imprisonment up to 5 years.
Mackisen CPA’s role is to turn potential prosecution into negotiation through documentation, cooperation, and defense.
Learning insight: Silence is protection; documentation is defense.
Preventing a Criminal Referral
Most CRA criminal investigations begin as civil audits. Early intervention by a CPA significantly reduces escalation risk. Mackisen CPA reviews every audit finding for exposure indicators such as:
“Gross negligence” wording in CRA correspondence.
Repeated disallowance of ITCs or deductions.
CRA requesting interviews beyond normal audit scope.
CRA contacting employees, suppliers, or family members.
Learning insight: Once CRA’s tone changes from “review” to “investigation,” you must change your response from accountant to defense.
