June 2023 Newsletter

If you are listed on the provincial or federal public companies register as being a “director” of any corporation (including a non-profit or a charity) — or even if you are not legally a director but are effectively responsible for an incorporated company — you need to be aware of the tax risks and of the steps you can take to protect yourself.

Every year, the Canada Revenue Agency (CRA) and Revenu Québec (RQ) assess hundreds of directors to collect debts owing by their companies. In many of these cases, the director was not aware of this risk and of what they could have done to avoid personal liability. Countless Canadians have had their assets confiscated and their lives ruined by this mistake.

(In the discussion below, references to the CRA apply to RQ as well. In Quebec, RQ administers not only provincial income tax and Quebec Sales Tax, but also the GST.)

What corporate tax liabilities can a director be assessed for?

The main tax liabilities are:

  • payroll deductions (income tax, CPP and EI) that were withheld and not remitted, or that should have been withheld
  • GST or HST (and in Quebec, QST) that the corporation collected, or should have collected, minus available deductions such as input tax credits (i.e., the corporation’s “net tax”)
  • interest and penalties on the above payable by the corporation, plus interest on the amount you are assessed from the time the CRA assesses you as a director.

There are other liabilities as well, such as for provincial retail sales taxes not collected, and certain other federal and provincial taxes.

Notably, a director is not liable for a corporation’s regular corporate income tax debt. However, in many cases a director (or shareholder) who has received anything from the corporation in any year since the year the tax liability arose, including a dividend, can be assessed under Income Tax Act section 160, the “transfer of property” rule, or the parallel GST rule in Excise Tax Act section 325.


What if you’re not a legal director?

If you’re a director, you’re liable for the corporation’s payroll deductions and GST/HST net tax, as noted above, and subject to various possible defences explained below. But you can also be liable if you’re a de facto director, i.e., a director in practice even if you’re not legally a director.

So, if you’re involved in running a company, or if the company is inactive but you’re the person dealing with the CRA on behalf of the company and answering questions about it, you may well be considered a de facto director. In such a case, you’ll be just as liable as if you had legally been a director.

The 2016 Koskocan decision of the Tax Court has limited the definition of de facto director somewhat by showing that officers, not directors, normally manage a company’s day-to-day affairs. However, whether you’re a de facto director will depend very much on the facts of your particular situation.

What about other directors?

All directors are jointly and severally liable (“solidarily” liable, in Quebec), meaning any one of them can be assessed for 100% of the debt.

In practice, the CRA may go after whoever seems to have the deepest pockets (ability to pay). Directors then have a right to “contribution” from each other, but that requires you to sue the other directors in provincial civil court for their portion of the liability, and those other directors may well be bankrupt or have no assets you can seize, even if your lawsuit succeeds.

What does the CRA need to prove?

Nothing. If you appeal the assessment, the onus is on you to prove that you are not liable because one of the defences below applies.

First defence: “I wasn’t a director”


If you never consented in writing to being appointed as a director, then perhaps you weren’t a director and aren’t liable. As noted above, however, you might have been a “de facto” director, by doing the things directors do (managing the company, signing documents on its behalf, or representing it).

If you weren’t a director or a de facto director when the corporation’s liability arose, you’re not liable for that liability. So if you became a director when the company already had a significant payroll or GST/HST liability, you might be able to escape the assessment.

Note however that remittances made while you were a director will normally have been applied by the CRA to the oldest debts (for which you wouldn’t have been liable), unless the company specifically told the CRA to apply them to the new debts. You may thus be liable for new remittance obligations even though the company made sufficient remittances while you were a director to cover those obligations.

What if you resigned before the liability arose (that is, before the date the corporation was required to remit the payroll deductions or GST/HST)? You’re not liable; but proving that you resigned and didn’t continue as a de facto director may be difficult. This issue is discussed under “Second defence” below.


Second defence: “I resigned more than 2 years before the assessment”

If you ceased to be a director more than two years before the Notice of Assessment is issued to you to assess you as a director, you’re not liable.

However, if your name wasn’t removed from the public registry of companies when you resigned, proving that you resigned may be difficult. The CRA is understandably suspicious of people who claim to have resigned more than two years ago but can’t really prove that they delivered their resignation letter to the company at the time. You’ll need to show from all the surrounding circumstances and other documentation that you really did resign.

Even if you resigned, if you continued to act as a de facto director, you’ll be out of luck.

If the company was dissolved more than two years before the assessment was issued, you ceased to be a director at that time. However, the CRA sometimes takes steps to ask a Court to “revive” a company retroactively, so that the directors can be assessed. This step can be opposed, but you’ll need professional advice from a lawyer familiar with this issue.

Note that there is no other limitation period. Even if the corporation’s failure to remit GST happened 25 years ago, you can be assessed for it, with astronomical compounded interest charges that vastly exceed the original amount of tax.

Third defence: “The assessment of the corporation was wrong”

If you can show that the company wasn’t in fact liable for the amount of payroll deductions or GST/HST the CRA claims it owed, then you should be able to get the assessment reduced or eliminated.

The CRA used to reject this defence, saying that if the company didn’t appeal its own assessment, that assessment is “deemed to be valid and binding” by the legislation and thus can no longer be challenged. The Tax Court was mixed in whether it accepted this reasoning. However, the Federal Court of Appeal made it clear, in the 2020 Duque case, that if you can show the corporation’s liability wasn’t as high as the CRA claims, you can get the assessment reduced. Doing this is difficult, however, if the supporting documentation has disappeared. Simply claiming that the debt “couldn’t possibly have been that high” won’t work; you need real proof.

Fourth Defence: “I met the due-diligence test”

This defence will be offered to you by the CRA when it first writes to you to propose assessing you as a director, and asking you if you have anything to say.

This defence is: “A director of a corporation is not liable for a [corporation’s] failure [to remit payroll deductions or GST/HST] where the director exercised the degree of care, diligence and skill to prevent the failure that a reasonably prudent person would have exercised in comparable circumstances.”

There have been hundreds of reported decisions from the Tax Court and the Federal Court of Appeal on this defence. This is an objective test: looking at your actions objectively, did you meet the test above? You have to show that you took active steps to ensure the taxes were being remitted, such as by setting up systems to make sure the remittances were made. Innocent good faith, or not being aware of the liability, will not be enough. As well, if there were “red flags” indicating that the company was in financial trouble, then you had an extra high obligation to make sure it was meeting its payroll and GST/HST obligations.

Note also that having taken active steps to remit the corporation’s outstanding liability — even if you put in your own money at that point — is irrelevant. You need to show that you met the due-diligence standard at the time the corporation’s remittance obligation arose — when the GST/HST return or payroll remittance was due.



If you are a company director, make sure the company is remitting all payroll and GST or HST it is required to remit. Be proactive: if you’re not running the company yourself, take active steps to ensure the remittances are actually being made. Document what you are doing, if you’re an outside director and are depending on others: sending your inquiries by email is one way of doing this. If you’re not sure the remittances are being made, resign, and ensure that your resignation is immediately recorded in the government registry of corporations — and then hope that two years go by without you being assessed.


If you’re not sure whether you’re a director, find out! A shareholder is not the same as a director; you can be one and not the other. Check the company’s minute book, or search the government companies register to find out if you’re listed. You need to know.

If you’re assessed as a director, or the CRA proposes to assess you, you should obtain professional advice as soon as possible to explore your options. You may be able to raise one of the defences above. Make sure you file a Notice of Objection with the CRA within 90 days of being assessed, or you may lose your right to appeal.
