CRA Payroll Benefits Audit 2025 — Protect Your Employees, Eliminate Penalties, and Ensure Full Compliance with Mackisen CPA

In 2025, CRA’s Payroll Benefits Audit Program is more aggressive than ever, targeting businesses across Canada for employee benefit misclassifications. CRA’s audit systems now automatically cross-check T4 slips, payroll remittances, and corporate expense accounts to detect taxable benefits that weren’t reported correctly — from company cars and allowances to health plans and bonuses. Even honest administrative mistakes can result in heavy reassessments, 10% penalties, and interest charges. At Mackisen CPA Auditors Montreal, we defend businesses and directors against CRA’s payroll benefit audits. Our CPA auditors and tax lawyers review your payroll structure, correct benefit classification errors, and build a full legal defense that restores compliance while minimizing financial impact. We don’t let CRA turn technicalities into penalties — we protect your employees, your company, and your peace of mind.
Legal and Regulatory Framework
Income Tax Act (Canada)
Section 6(1)(a): Requires inclusion of taxable employment benefits in employee income.
Section 153(1): Mandates proper withholding and remittance of payroll deductions.
Section 227.1: Holds directors personally liable for unremitted payroll taxes unless due diligence is proven.
Section 220(3.1): Permits CRA to cancel or reduce penalties and interest under the Taxpayer Relief Program.
Employment Insurance Act & Canada Pension Plan Act
CRA verifies benefit-related contributions for CPP and EI during payroll audits.
Tax Administration Act (Quebec)
Revenu Québec audits QPP, QPIP, and HSF payroll benefits in parallel with CRA. Mackisen manages both authorities to ensure consistent treatment.
Key Court Decisions
Thibault v. The Queen (2022): CRA must prove a benefit was personal, not business-related, before reassessment.
Bédard v. The Queen (2022): Proper documentation of business purpose shields employers from taxable benefit penalties.
Guindon v. Canada (2015): Honest reliance on payroll or accounting professionals negates gross negligence penalties.
Jordan v. The Queen (2009): CRA cannot assume unreported benefits without verifiable evidence.
These decisions confirm that CRA payroll benefit audits can be overturned with documentation, proof of intent, and professional representation.
Why CRA Targets Payroll Benefits
CRA audits payroll benefits to capture unreported or improperly classified items that increase tax revenue. Common 2025 triggers include:
Employer-provided vehicles or allowances.
Company-paid health or life insurance premiums.
Housing, travel, or gift card benefits.
Missing or incorrect T4A/T4 reporting.
Payroll deductions inconsistent with benefits provided.
CRA assumes non-compliance — Mackisen proves accuracy.
Mackisen’s Payroll Benefits Audit Defense Strategy
Audit File Review: Examine CRA’s audit letter, payroll reports, and T4 summaries for errors or inconsistencies.
Benefit Classification Analysis: Review all taxable and non-taxable benefits against CRA guidelines.
Payroll Reconciliation: Rebuild accurate payroll data to support compliance and correct remittance differences.
Formal Objection: File a Notice of Objection within 90 days to pause CRA enforcement and protect your rights.
Penalty & Interest Relief: File under Section 220(3.1) to remove financial penalties for administrative oversight.
Our approach ensures your payroll system is compliant, fair, and defensible under Canadian tax law.
Real Client Experience
A Montreal engineering firm was reassessed $142,000 for “unreported vehicle benefits.” Mackisen recalculated taxable benefits and reduced CRA’s assessment by 92%.
A Quebec tech company faced $85,000 in penalties for employee allowances. Mackisen proved they were non-taxable reimbursements and secured a full cancellation.
