Director Liability for Unremitted GST/HST in Canada

18 Jun 2026 5 min read No comments Money, Taxes & IP Canada
⚠️

If your Canadian corporation fails to remit GST/HST, the Canada Revenue Agency (CRA) can bypass the corporate veil and hold you, as a director, personally liable for the debt. The strongest legal shield is the “due diligence” defence, proving you took active steps to ensure the taxes were paid. Do not ignore a CRA assessment.

Incorporating a business in Canada generally protects business owners from being personally responsible for corporate debts. Whether your company operates in Halifax, Ottawa, or Edmonton, this legal concept-known as the “corporate veil”-is a primary reason entrepreneurs choose to incorporate. However, the corporate veil offers absolutely no protection when it comes to trust fund taxes. Under federal law, the Goods and Services Tax (GST), Harmonized Sales Tax (HST), and employee payroll deductions are not corporate money. They are considered funds held in trust for the Crown.

When a corporation struggles financially, directors often make the fatal mistake of paying suppliers or landlords using the GST/HST they collected from customers. 💸 Under Section 323 of the Excise Tax Act, if the corporation goes bankrupt or ignores its tax bills, the Canada Revenue Agency (CRA) can and will aggressively pursue the corporate directors personally to recover the unremitted funds, plus compounding interest and heavy penalties. Defending yourself against these assessments requires deep knowledge of Canadian tax litigation. If you are facing director liability, it is critical to seek out a specialized tax lawyer from our directory immediately to explore your options.

Step-by-Step Process for Defending Against CRA Director Liability

Fighting a personal assessment from the CRA is a highly structured legal process. The burden of proof rests entirely on your shoulders as the director. Here is the general procedure to defend yourself.

Step 1: Receiving the CRA Notice of Assessment

The process begins when you receive a personal Notice of Assessment (NOA) from the CRA stating that you are jointly and severally liable for your corporation’s unremitted GST/HST. You must not ignore this letter. 📬 The CRA has immense collection powers and can freeze your personal bank accounts, garnish your wages, or place a lien on your family home without needing a court order.

Step 2: Establishing the Two-Year Limitation Period

Your lawyer will immediately check if the CRA has missed their legal deadline. Under Canadian law, a director cannot be assessed for a corporation’s tax debt more than two years after they officially ceased to be a director. You must prove you legally resigned by showing the filed notice of change of directors with the provincial registry (like ServiceOntario or the Alberta Corporate Registry) or Corporations Canada.

Step 3: Building the Due Diligence Defence

If the limitation period has not expired, your primary weapon is the “due diligence” defence. 🔍 You must prove that you exercised the degree of care, diligence, and skill to prevent the failure that a reasonably prudent person would have exercised in comparable circumstances. It is not enough to say you didn’t know the taxes weren’t paid. You must show you took active steps, such as setting up a separate trust account for GST/HST, requesting regular tax compliance reports from your accountant, or demanding corrective action when you discovered financial trouble.

Step 4: Filing a Notice of Objection

You have exactly 90 days from the date on the Notice of Assessment to formally challenge it by filing a Notice of Objection. This halts the CRA’s personal collection actions against you while an independent Appeals Officer reviews your due diligence evidence and legal arguments. Missing this 90-day deadline usually means you lose your right to fight the debt entirely.

Step 5: Appealing to the Tax Court of Canada

If the CRA Appeals Division rejects your objection and confirms the assessment, your final legal recourse is to file an appeal with the Tax Court of Canada. 💬 At this stage, your tax lawyer will represent you in formal litigation against the Department of Justice, calling witnesses and presenting financial records to a judge to prove you met the strict due diligence standard.

How Much Does it Cost to Defend a CRA Assessment?

Litigating against the federal government is expensive, but it is often necessary to avoid personal bankruptcy. Anticipate the following general costs:

  • CRA Debt: The principal unremitted tax, plus daily compounding interest and a potential failure-to-remit penalty.
  • Notice of Objection Legal Fees: Generally $3,000 to $7,000 CAD for a tax lawyer to review the corporation’s books and draft the legal arguments.
  • Tax Court Litigation: Taking a director liability case through trial at the Tax Court of Canada can easily cost between $15,000 and $30,000+ CAD, depending on the complexity of the corporation’s accounting.

How Long Does the Process Take?

Resolving a director liability dispute is a test of endurance. You have 90 days to file your Notice of Objection. Once filed, it may take the CRA Appeals Division anywhere from 6 to 12 months to assign an officer and render a decision. If you must proceed to the Tax Court of Canada, expect the litigation process-from filing the Notice of Appeal to receiving the judge’s final ruling-to take an additional 1 to 3 years.

Frequently Asked Questions (FAQ)

I was only a “silent” or outside director. Am I still liable?

Yes. The CRA does not care if you were an outside director, a silent partner, or only joined the board as a favour to a family member. Every legally registered director has a positive, statutory duty to ensure trust fund taxes are remitted. Your due diligence requirement might be slightly different than a managing director, but you cannot use “ignorance” as a valid defence.

Can I declare personal bankruptcy to clear the CRA debt?

In Canada, a personal bankruptcy or Consumer Proposal can generally include CRA tax debts, including director liability assessments for GST/HST. However, this is a severe financial decision that will heavily damage your credit rating for years, and you should consult a Licensed Insolvency Trustee.

Does a corporate bankruptcy stop the CRA from coming after me?

No. In fact, a corporate bankruptcy is often the exact trigger event that causes the CRA to look past the corporation and assess the directors personally under the Excise Tax Act.

What if the corporation just didn’t have the money to pay the tax?

Financial hardship is not a valid legal defence. The GST/HST collected from customers belongs to the government. If you used those specific funds to pay employee wages, rent, or suppliers to keep the business afloat, the Tax Court will view this as a conscious choice to breach your duty to the Crown, and you will be held liable.
