Audit-Proof Your Books

An organized business is a protected business. Disorganized financial records are the number one reason CRA and Revenu Québec issue reassessments, penalties, and interest charges. Audit-proofing your books means creating systems that withstand inspection anytime, without stress or missing documents. Mackisen CPA Auditors Montreal helps businesses across Canada build audit-ready systems that combine accuracy, structure, and CPA oversight to eliminate compliance risks and maintain credibility.

Legal and Regulatory Framework

Taxation Act (Quebec) Section 34: Obligates all registered entities to retain documents supporting QST and income reporting.
CPA Canada Handbook Section 5050: Establishes audit readiness and verification standards for accountants.

Key Court Decisions

Why CRA Targets / Issues / Enforces
CRA uses artificial intelligence to flag inconsistencies between filings, bank records, and GST/QST submissions. Businesses with poor documentation face automatic audit escalation. Mackisen CPA Auditors Montreal designs systems that maintain verifiable, timestamped audit trails to protect against reassessment and ensure transparency.
