Defending Against CRA Unremitted Source Deductions Assessments in Canada

17 Jun 2026 5 min read No comments CRA Tax Disputes & Audits Canada
💡

The CRA treats unremitted source deductions (CPP, EI, and Income Tax) as stolen government trust funds. If a corporation fails to pay, the CRA will hold the corporate directors personally liable for the debt. You must act immediately, as you only have 90 days to file a Notice of Objection and mount a due diligence defence.

Understanding Unremitted Source Deductions in Canada

When a Canadian business runs into cash flow problems, owners often make the fatal mistake of prioritizing their suppliers and rent over their Canada Revenue Agency (CRA) payroll remittances. Every time you pay an employee in Ontario, Alberta, or any other province, you deduct Canada Pension Plan (CPP) contributions, Employment Insurance (EI) premiums, and personal income tax from their gross wages. Legally, this money does not belong to your company; it belongs to the Receiver General for Canada. You are merely holding it in a “deemed trust.”

Because this money belongs to the employees and the government, the CRA pursues unremitted source deductions more aggressively than any other type of tax debt. If the corporation ignores the debt or goes bankrupt, the CRA will pierce the corporate veil under Section 227.1 of the Income Tax Act. 🚨 They will issue personal assessments directly against the directors of the company, seizing their personal bank accounts, placing liens on their family homes, and garnishing their personal wages. Defending against these devastating Trust Examiner actions requires highly specialized legal representation.

Step-by-Step Process to Defend Against the CRA

If a CRA Trust Examiner contacts your business demanding immediate payment for payroll arrears, panic is not a strategy. You must engage a Canadian tax law firm immediately to protect your corporate and personal assets. Here is how the defence is structured.

Step 1: Halting Aggressive CRA Collections

Unlike standard corporate income tax disputes where collections are paused during an appeal, the CRA is legally permitted to take aggressive collection actions for trust funds immediately. Your lawyer must quickly contact the CRA Collections Officer to negotiate a structured payment arrangement. By showing good faith and providing post-dated cheques or a realistic payment plan, you can stop the CRA from freezing the company’s operating bank accounts, which would otherwise paralyze the business.

Step 2: Conducting a Payroll Audit Review

Before accepting the CRA’s massive tax bill, your legal team and accountants must verify the math. The CRA’s automated systems frequently misapply payments or miscalculate the complex 10% to 20% failure-to-remit penalties. You will review all T4 summaries, payroll ledgers, and bank statements to ensure that every cent you actually remitted to the Receiver General was correctly credited to your payroll account.

Step 3: Establishing the Due Diligence Defence

If the CRA officially assesses the corporate directors personally, the strongest legal shield is the “Due Diligence Defence.” Under Canadian law, a director is not personally liable if they can prove they exercised the degree of care, diligence, and skill that a reasonably prudent person would have exercised to prevent the failure to remit. ⚖️ Your lawyer will gather board meeting minutes, emails to external accountants, and internal memos proving that you actively set up systems to pay the CRA, but the failure occurred due to unforeseen disasters (like a massive client bankruptcy or sudden banking freezes) rather than negligence.

Step 4: Filing the Notice of Objection

If the Trust Examiner’s assessment is mathematically incorrect, or if they have wrongly assessed a director personally, you must file a formal Notice of Objection. You have exactly 90 days from the date on the personal Notice of Assessment to file. This legal document halts the finalization of the debt and forces an independent CRA Appeals Officer to review your due diligence arguments. If the Appeals Officer refuses to drop the personal assessment, you must appeal directly to the Tax Court of Canada.

How Much Does it Cost in Canada?

Failing to remit payroll taxes triggers some of the harshest financial penalties in the Canadian tax code. Securing a lawyer is critical to mitigating these crippling costs.

Penalty / ExpenseEstimated Cost (CAD)Details
First-Time Failure to Remit Penalty10% of the unremitted amountAutomatically applied if you miss the remittance deadline by even one day
Subsequent Failures Penalty20% of the unremitted amountApplied for repeat offences within the same calendar year
CRA Compounding InterestPrescribed Rate + 4%Interest is compounded daily on both the debt and the penalties
Tax Lawyer Retainer$5,000 – $15,000+To fight personal director liability and file the objection

Attempting to dodge the debt by shutting down the corporation will not work; the CRA will simply transfer the entire balance, plus penalties, directly to the directors’ personal Social Insurance Numbers (SIN).

How Long Does the Process Take?

CRA Trust Examiners move incredibly fast. If you miss a payroll remittance, you can expect collection letters within 15 to 30 days. If the corporation cannot pay, the CRA will issue a proposal to assess the directors personally. Once a director files a Notice of Objection, the process slows down dramatically. It can take the CRA Appeals Division 8 to 14 months to review the due diligence defence, during which time the stressful threat of personal liability hangs over the director’s head.

Frequently Asked Questions (FAQ)

Can I go to jail for not remitting source deductions?

While extremely rare, yes. Under the Income Tax Act, intentional tax evasion and severe fraud regarding trust funds can lead to criminal prosecution, which carries massive fines and up to 5 years in federal prison. However, most cases are handled civilly through severe financial penalties.

Will corporate bankruptcy erase this debt?

No. If the corporation files for bankruptcy, the deemed trust for unremitted source deductions survives. The CRA will immediately transfer the debt to the directors personally. Only a personal bankruptcy or personal consumer proposal can potentially clear a director’s personal liability for the debt.

I was a silent director. Am I still liable?

Yes. The CRA does not care if you were a “silent partner” or just signed the incorporation papers as a favour. If your name is listed on the provincial or federal corporate registry as a director, you bear joint and several personal liability for the unremitted trust funds.

Can the CRA seize my house for corporate payroll debt?

If the CRA successfully assesses you personally under Director’s Liability, they have the legal authority to register a tax lien against your personal real estate. If the debt remains unpaid, they can eventually force the sale of the property to recover the trust funds.

What is the two-year limitation period?

Under Canadian law, a director cannot be assessed for unremitted source deductions if more than two years have passed since they officially resigned. However, the resignation must be legally filed with the corporate registry; simply walking away from the business is not enough to start the two-year clock.
