CRA Corporate Tax Penalty Appeal 2025 — Eliminate Unfair Fines, Restore Compliance, and Protect Your Business Reputation

In 2025, CRA’s Corporate Tax Penalty Enforcement Program has become more aggressive than ever. Thousands of corporations across Canada are being hit with automatic penalties for late filings, incorrect remittances, or technical reporting errors — even when caused by software glitches or external accountants. CRA’s systems apply penalties before human review, leaving many companies paying fines they don’t owe. At Mackisen CPA Auditors Montreal, we defend corporations against unfair CRA penalties and reassessments. Our CPA auditors and tax lawyers analyze every charge, identify administrative or legal grounds for relief, and file formal appeals under the Taxpayer Relief Program. We don’t let CRA automation destroy your cash flow — we fight for fairness and accountability.
Legal and Regulatory Framework
Income Tax Act (Canada)
Section 162(1): Imposes penalties for late filing or inaccurate returns.
Section 163(2): Adds 50% gross negligence penalties that Mackisen can challenge and remove.
Section 220(3.1): Authorizes CRA to cancel penalties and interest under the Taxpayer Relief Provisions.
Section 152(4): Restricts reassessment periods unless CRA proves deliberate misrepresentation.
Tax Administration Act (Quebec)
Revenu Québec enforces similar penalty structures for corporate tax, QST, and payroll filings. Mackisen coordinates both agencies to ensure relief across all jurisdictions.
Key Court Decisions
Guindon v. Canada (2015): Penalties require intent — administrative errors are not grounds for gross negligence.
Bédard v. The Queen (2022): CRA must evaluate reasonable cause before imposing late-filing penalties.
Thibault v. The Queen (2022): Courts favor businesses that acted in good faith or relied on professional advice.
Venne v. The Queen (1984): CRA cannot arbitrarily apply penalties without substantiated evidence.
These precedents confirm that CRA penalties can be removed or reduced with proper documentation and professional representation.
Why CRA Imposes Corporate Tax Penalties
CRA’s automated penalty assessments often result from data mismatches or procedural delays. Common 2025 triggers include:
Late corporate income tax or GST/HST filings.
Inaccurate payroll deductions or source remittances.
Missing or incorrect T2 schedules.
Software transmission errors or accountant oversight.
CRA system delays misattributed to taxpayers.
CRA assumes fault — Mackisen proves reasonableness.
Mackisen’s Corporate Penalty Appeal Strategy
Penalty Review: Examine CRA’s assessment notice and identify procedural or factual errors.
Documentation Collection: Gather correspondence, proof of filing, and payment confirmations to prove compliance.
Formal Appeal: File a detailed Taxpayer Relief Application under Section 220(3.1) to cancel or reduce penalties.
Negotiation & Resolution: Engage directly with CRA Appeals Officers to secure a favorable decision.
Compliance Reinforcement: Implement internal processes to prevent future penalties and protect your business.
Our method combines accounting precision with legal advocacy to remove unnecessary financial burdens.
Real Client Experience
A Montreal manufacturing firm was fined $76,000 for late remittances after system errors. Mackisen proved CRA’s delay and secured full penalty cancellation.
A Quebec professional corporation faced $41,000 in filing penalties after their accountant missed deadlines. Mackisen demonstrated due diligence and achieved a 100% reversal.
Common Questions
Can CRA remove penalties for late filing? Yes — if you show reasonable cause, Mackisen can file for full relief.
Can I appeal penalties more than once? Yes, if new evidence or circumstances arise.
Do penalties accrue during appeal? No, filing a relief application suspends additional interest accumulation.
Can CRA reject my relief request? They can, but Mackisen can escalate to Tax Court or negotiate reconsideration.
