ARQ Compliance Audit (Conformité) — Montreal CPA Firm Near You: Filings Up-to-Date

An ARQ Compliance Audit (Vérification de conformité) is a broad administrative review by Revenu Québec to confirm that your business or personal tax accounts are registered, filed, and paid up to date. Unlike investigative audits, this verification ensures compliance across all tax accounts—QST, GST/HST, source deductions, corporate income tax, and payroll remittances. Mackisen CPA Montreal manages your compliance health check from start to finish, ensuring that no filing, remittance, or declaration is missed or delayed.

Legal Foundation

Law: Tax Administration Act (Québec) art. 93 (authority to verify compliance and request filings); Taxation Act ss. 1000–1010 (filing obligations and penalties).
Jurisprudence: Bédard v. ARQ (2010 CQ) — affirmed that compliance audits must be based on clear evidence of missing filings and that taxpayers have the right to rectify omissions before reassessment.

Why You Need a CPA for a Compliance Audit

Compliance audits seem routine but can expose serious risks if not handled properly. Revenu Québec uses them to verify that all registrations (NEQ, QST, GST, payroll) are active and consistent across government databases. Missing a single return—even a nil return—can trigger penalties, interest, or suspension of tax numbers. Mackisen CPA Montreal conducts a pre-compliance review to detect and correct these issues before ARQ flags them.

Learning insight: Compliance is not about paying more—it’s about proving everything is complete. Prevention is your most profitable tax strategy.

What Mackisen CPA’s Compliance Audit Service Includes

• Full diagnostic of CRA and ARQ accounts for unfiled or duplicate returns.

• Cross-verification of QST, GST, payroll, and corporate registration data.

Learning insight: The best audit response is no audit at all. A CPA keeps your compliance invisible by keeping it perfect.

Common Triggers for ARQ Compliance Audits

• Late or missing QST, GST, or source-deduction filings.

• Payroll accounts showing inconsistent remittances vs. T4/RL-1 data.

• Businesses changing addresses or legal status without updating Revenu Québec.

• New or inactive accounts under the same NEQ.

• ARQ “risk-score” algorithms detecting long filing gaps or non-response patterns.

Mackisen CPA Montreal anticipates and corrects these issues, preventing escalation to a verification of revenues or field audit.
