If you sit on the board of a Canadian corporation, your personal finances may be more exposed than you realise. Under federal tax legislation, the Canada Revenue Agency can reach past the corporate veil and hold individual directors personally responsible for certain unpaid corporate tax debts. For Calgary business owners and board members, understanding this exposure — and the defences available — is essential financial planning, not just legal trivia.
Director liability for corporate tax debts in Canada flows from two primary statutory sources. Section 227.1 of the Income Tax Act (ITA) covers payroll-related remittances, while Section 323 of the Excise Tax Act (ETA) covers GST/HST. Together, these provisions create joint and several liability — meaning CRA can pursue any director, or all directors simultaneously, for the full amount owed.
The key phrase in both sections is that directors are liable when the corporation "has failed to remit" amounts it was required to send to the Receiver General. This is not about the corporation failing to pay its own corporate income tax. It is specifically about amounts the corporation collected or withheld on behalf of the government and then failed to forward.
Every pay period, a Canadian employer is required to deduct income tax, Canada Pension Plan (CPP) contributions, and Employment Insurance (EI) premiums from employee paycheques and remit them to CRA along with the employer's share of CPP and EI. When a corporation fails to do this, every director who held office at the time of the failure becomes personally liable.
The amounts at stake include:
These figures accumulate quickly. A corporation with a monthly payroll of $80,000 can generate CRA arrears exceeding $25,000 in a single quarter if remittances are missed. Directors are liable for all of it, jointly and severally, which means CRA can issue a notice of assessment directly to any director for the entire balance — not just their proportionate share.
The rules under ETA Section 323 mirror those for payroll remittances. When a corporation collects GST/HST from its customers and fails to remit that money to CRA, each director at the time of the failure is personally on the hook for the unremitted tax, plus interest and penalties.
This is a meaningful distinction worth emphasising: this is money the corporation already collected from customers. It was never the corporation's money to begin with. CRA views non-remittance of collected HST with particular seriousness, and directors who allow HST arrears to accumulate while the corporation continues to trade face significant personal exposure.
For GST/HST liability to attach, CRA must first have either obtained a certificate against the corporation in Federal Court, or the corporation must have commenced insolvency proceedings. This procedural requirement does not apply in the same way to payroll remittance liability, making payroll arguably the more immediate risk for most directors.
Both the ITA and ETA provide a defence for directors who exercised the degree of care, diligence, and skill that a reasonably prudent person would have exercised in comparable circumstances to prevent the failure to remit. This is a meaningful but demanding standard.
Two points about this defence are frequently misunderstood. First, it must be directed at preventing the failure, not merely responding to it after the fact. Discovering arrears and attempting to arrange a payment plan does not satisfy the due diligence standard — that is a remedial step, not a preventive one. Second, the standard differs for active and passive directors.
An active director — someone involved in day-to-day management — is held to a higher standard. Courts expect them to have systems in place to monitor payroll accounts, receive CRA correspondence directly, and escalate concerns when cash flow problems emerge. Saying "I trusted the bookkeeper" generally will not suffice for an active director.
A passive or outside director — someone appointed primarily for governance, expertise, or networking purposes — faces scrutiny based on their specific circumstances. They must still show they raised concerns when red flags appeared, asked questions about remittance compliance at board meetings, and took reasonable steps given their level of involvement. Passivity alone does not provide protection; it simply calibrates the standard applied.
Successful due diligence defences typically involve evidence of: regular review of CRA My Business Account or payroll remittance summaries, documented board discussions about financial controls, prompt escalation when arrears first appeared, and independent legal or accounting advice sought proactively. The team at Swift Accounting in Calgary frequently helps directors establish and document these monitoring systems before problems arise.
One of the most important — and most misunderstood — protections for directors is the two-year limitation period under both the ITA and ETA. CRA has only two years from the date a director ceases to be a director to issue an assessment against that person. If CRA does not assess within that window, the liability is extinguished.
This means that a director who resigned from a corporation years before CRA audits the company's payroll account may have no personal liability at all, even if the corporation owes significant arrears. The clock starts running when the directorship ends — not when the debt arose, and not when CRA discovers the problem.
Because resignation triggers the two-year limitation period, CRA scrutinises the legal effectiveness of resignations carefully. It is not enough to decide to resign, tell the other directors you are resigning, or stop attending board meetings. The resignation must be legally effective.
A legally effective resignation typically requires: a written resignation document signed and dated, delivery of that resignation to the corporation, and — critically — updating the corporate registry with the relevant provincial authority (in Alberta, Corporations Canada for federal corporations, or the Alberta Corporate Registry for provincial ones). CRA will examine registry records, corporate minute books, and correspondence to determine the actual date a director ceased to hold office. If the registry was never updated, CRA may take the position that the director remained in office regardless of their subjective intention.
Some business arrangements involve nominee directors — individuals listed on corporate registry in name only, with the actual control exercised by someone else. Under Canadian law, this structure provides essentially no protection. A nominee director is a director in the eyes of CRA, subject to the full scope of liability under ITA Section 227.1 and ETA Section 323.
Courts have consistently rejected the argument that a nominee director lacked real authority and therefore should not be liable. The legal position is the position. If you have agreed to serve as a director, even nominally, you carry the same personal exposure as any actively engaged board member.
Practical steps that reduce director liability risk include:
Swift Accounting Calgary works with business owners and directors to establish compliance systems that create a documented record of diligent oversight — the kind of evidence that supports a successful due diligence defence.
Director liability assessments from CRA are not theoretical risks. They are issued regularly, often years after a corporation has closed or gone insolvent, and they arrive with the full interest and penalty load accumulated over that period. The time to address this exposure is while you are still a director and can influence the corporation's compliance — not after CRA has issued a notice of assessment in your name.
If your corporation has outstanding payroll or HST arrears, or if you are concerned about your exposure as a current or former director, professional advice is essential. Contact Swift Accounting today to discuss your situation and understand your options before CRA takes action.
Yes. Under ITA Section 227.1 and ETA Section 323, liability attaches to all directors at the time of the failure to remit, regardless of their involvement in financial decisions. Even if you served in a governance or advisory capacity and never touched the payroll system, CRA can assess you for the full amount of unremitted payroll deductions or HST. Your best protection is demonstrating that you actively took steps to prevent the failure — which requires some engagement with the corporation's remittance compliance, even at a high level.
If your resignation was legally effective — properly documented, signed, and reflected in the corporate registry — and more than two years have passed since you ceased to be a director, CRA is generally statute-barred from assessing you. The two-year limitation period under the ITA and ETA is a hard deadline. However, CRA may dispute the effective date of your resignation if the registry was not updated or if there is evidence you continued to act as a director after your stated resignation date. It is worth confirming with a professional advisor that your resignation was properly completed.
This is one of the most common points of confusion. Director liability under ITA Section 227.1 applies only to payroll source deductions — amounts the corporation withheld from employees and employer matching contributions — that were not remitted to CRA. It does not extend to the corporation's own corporate income tax liability. If a corporation fails to pay its corporate tax bill, that debt belongs to the corporation, and CRA generally cannot pursue individual directors for it (unless there are separate grounds such as tax planning transactions caught by other rules). GST/HST liability under ETA Section 323 is similarly limited to unremitted amounts collected from customers.
Partially and indirectly. Standard D&O policies are designed to cover claims arising from wrongful acts in a director's governance capacity — they typically cover defence costs and damages in civil litigation. Many policies exclude or limit coverage for statutory tax liabilities, meaning the underlying CRA assessment itself may not be covered. However, D&O insurance can provide meaningful coverage for legal fees incurred defending against a CRA assessment or related proceedings, and some policies include tax liability coverage as an endorsement. Review your policy wording carefully with your insurance broker and confirm what is and is not covered before relying on it as a primary risk management tool.
