Director Personal Liability: How to Protect Yourself From Unpaid Corporate Taxes in Canada

Many directors believe incorporation shields them personally from tax debts. But under Canadian law, director personal liability can arise if a company fails to pay required taxes. Knowing the rules, defences, and proactive steps can help you stay protected.

When Does Director Personal Liability Apply?

Under section 227.1 of the Income Tax Act, directors can be jointly and severally liable for unpaid corporate taxes, plus penalties and interest. This means the CRA can demand payment from any or all directors if the company defaults. Similar rules apply under the Employment Insurance Act and Canada Pension Plan, covering unpaid source deductions and remittances.

Types of tax debts that can trigger liability:

  • Unremitted payroll source deductions
  • Unpaid GST/HST collected on sales
  • Outstanding corporate income taxes

Understanding director personal liability helps directors manage risk and avoid unexpected personal exposure.

CRA Must Meet Three Legal Conditions

Before directors can be held personally liable, the CRA must prove:

  1. Collection failure: The CRA first tried and failed to recover the debt directly from the company.
  2. Time limit: The CRA’s claim must be made within two years after the person ceased to be a director.
  3. Lack of due diligence: The director did not act with the care, diligence and skill a reasonably prudent person would show.

If these conditions aren’t met, directors may successfully challenge the claim.

The Due Diligence Defence

The strongest defence to director personal liability is proving you took reasonable steps to ensure tax compliance. Examples include:

  • Regularly reviewing financial and tax reports
  • Confirming payroll and GST/HST remittances were made on time
  • Asking questions when cash flow problems arise
  • Documenting decisions in board minutes

Passive reliance on staff or accountants isn’t enough—directors must actively monitor and act.

Practical Tips to Reduce Your Risk

Directors can reduce liability by:

  • Requesting regular proof of tax payments
  • Keeping tax funds in separate accounts
  • Documenting all oversight actions and discussions
  • Seeking advice from tax professionals when unsure

These habits demonstrate proactive oversight and strengthen your due diligence defence.

FAQs About Director Personal Liability

1. Can former directors be pursued?

2. Does resigning immediately protect me?

No. You may still be liable for debts that arose during your term if the CRA claims within the time limit.

3. Is relying on an accountant enough?

No. Directors must actively review and ask questions; passive reliance is not a defence.

4. What taxes create personal risk?

Mainly payroll source deductions, GST/HST, and corporate income tax debts.

5. Do volunteer directors face the same liability?

Yes, unless covered by limited liability protections for certain nonprofits.

Conclusion

Director personal liability for unpaid corporate taxes is real—but preventable. By understanding the CRA rules, documenting due diligence, and seeking advice early, directors can protect themselves and ensure their company meets its tax obligations.
