Cancelling Interest After Illness Derailed a Small Windsor Corporation

The situation

Huong worked full-time as a security guard at a Windsor facility, but on evenings and weekends he ran a small incorporated consulting practice on the side, assessing physical security for retail stores and small offices around the city. His spouse Minh, who worked as an administrative assistant, was the corporation's other director and handled the books: invoicing clients, remitting HST, and keeping the corporation's annual filings on schedule. It was a modest operation, but a disciplined one. In six years, the corporation had never missed a filing deadline.

Late one winter, Huong was diagnosed with a serious illness that required months of treatment, including a period of hospitalization and a long recovery at home. Minh became his full-time caregiver on top of her own job. The consulting side of the business stopped taking new clients almost overnight, and so did the bookkeeping that kept it compliant with the Canada Revenue Agency, known as CRA.

What the review found

By the time Minh was able to return to the corporation's paperwork, close to a year had passed. The corporation's tax return for the year of the diagnosis had been filed late, and the instalment payments the corporation normally made throughout the year toward its own tax bill had stopped entirely during Huong's treatment. When Minh finally filed the return and CRA processed it, the notice of assessment showed the corporation owed roughly $28,000 in unpaid corporate tax. Layered on top of that was roughly $16,000 in compound daily interest that had accrued month after month while the debt sat unpaid, plus a late-filing penalty of about $5,000. Altogether, the corporation owed close to $49,000, and more than $21,000 of that was interest and penalties rather than tax itself.

Minh called our office after CRA's collections division sent a letter warning that enforcement action, including a possible lien against corporate assets, could follow if the balance wasn't addressed. She was not disputing that the tax was owed. What troubled her was that a full third of the bill had been generated by a year in which the household had been dealing with a medical emergency, not indifference to their obligations.

This is where the Income Tax Act gives CRA a specific, discretionary tool called taxpayer relief. Under this provision, CRA can cancel or waive interest and penalties — though never the underlying tax itself — where a taxpayer's ability to comply was genuinely affected by circumstances beyond their control. Serious illness, natural disasters, and other extraordinary events all qualify in principle. What CRA actually wants to see is a clear, documented link between the hardship and the specific periods where compliance broke down, not just a general hard-luck story.

What we did

1. Mapped the corporation's compliance history against the illness timeline. We built a month-by-month picture showing that the corporation's filings and instalments were current right up until the diagnosis, stopped almost entirely during the worst of the treatment, and resumed once Minh was able to take the books back over. This mattered because taxpayer relief requests succeed or fail on specificity — CRA needed to see that the gap in compliance tracked the illness precisely, not that the corporation had simply been careless for a stretch.
2. Gathered supporting medical documentation. With Huong and Minh's consent, we helped them request a letter from Huong's treating physician, Etienne, confirming the diagnosis, the treatment period, and the extent to which it limited his and Minh's ability to manage ordinary responsibilities. CRA's guidelines expect this kind of corroboration; a request built only on a client's own narrative carries far less weight.
3. Distinguished the tax owed from the interest and penalties in dispute. We were careful throughout to frame the request correctly: the corporation was not asking CRA to forgive the $28,000 in tax it legitimately owed, only the interest and penalties that had accumulated on top of it during the period Huong and Minh could show was beyond their control. Requests that blur this line tend to be viewed with more skepticism.
4. Prepared the written taxpayer relief request. We drafted a formal submission to CRA setting out the timeline, attaching the medical documentation, and identifying the specific interest and penalty amounts the corporation was asking CRA to cancel. We also proposed a payment plan for the underlying tax so that CRA could see the corporation intended to resolve the debt promptly once the interest question was settled, rather than using the request to delay payment.
5. Followed up on the corporation's behalf while the request was under review. Taxpayer relief requests are handled by a CRA officer who can take several months to reach a decision. We monitored the file, responded to a follow-up request for the corporation's instalment records, and kept Huong and Minh updated so they weren't left guessing about where things stood.

The outcome

Several months after the request was submitted, CRA's decision letter arrived. The reviewing officer accepted that Huong's illness constituted circumstances beyond the corporation's control for the period in question and agreed to cancel the late-filing penalty in full and most of the accrued interest, roughly $19,000 of the $21,000 requested. A small residual amount of interest, tied to weeks just before the diagnosis and just after Minh resumed the books, remained payable, since that portion fell outside the window CRA accepted as directly affected by the illness.

The result left the corporation owing its original $28,000 in tax plus about $2,000 in interest that had not been cancelled — a debt Huong and Minh could manage through the payment arrangement we had already proposed, rather than the nearly $49,000 CRA had originally assessed. Because the request was granted, the corporation avoided the collections action that had been threatened, and its compliance record going forward was unaffected by the gap during Huong's treatment.

Taxpayer relief requests are not guaranteed to succeed, and CRA has full discretion in deciding them — there is no right of appeal to the Tax Court of Canada if a request is refused, only a request for a second, independent review within CRA itself. What made this one work was precision: a request that named the exact amount of interest and penalty being disputed, tied it to a documented and dated period of genuine hardship, and left no doubt that the corporation intended to pay what it legitimately owed.

For Huong and Minh, the practical difference was significant. Paying down $30,000 over a manageable arrangement, once Huong was back at work and the consulting practice was slowly taking clients again, was realistic for the household. Servicing a $49,000 balance on top of Huong's medical recovery would have meant either draining savings meant for something else or falling further behind, which in turn would have generated still more interest. The relief request didn't erase the debt, but it brought it back down to a size that matched what the corporation had actually earned and owed, rather than what a year of compounding had inflated it into.
