Reopening a badly settled instalment interest dispute for a Belleville family

The situation

What Gita was actually afraid of was not the letter itself, it was what would happen when she and Prakash went to refinance their rental property the following spring. Their mortgage broker had mentioned, almost in passing, that an outstanding CRA debt registered against a corporation could complicate a refinance if it turned into a lien, and once Gita heard the word lien she could not stop thinking about it, even after Prakash pointed out that nothing had actually been registered yet.

Gita worked as a millwright at an industrial plant outside Belleville, and Prakash worked as a respiratory therapist at a local hospital; the rental property, a modest triplex, had been held through a small corporation for tax and liability reasons since they bought it six years earlier. For most of those years the property had barely broken even, once mortgage interest, repairs and vacancy were accounted for. The year everything changed, the corporation turned its first real profit, largely because a fixed-rate mortgage renewed at a lower rate and two long-term tenants stayed through the year without a vacancy.

A profitable year meant the corporation owed instalments for the first time, and Dov, the accountant who had prepared the corporation's returns for years, had not adjusted the instalment approach to reflect it. Instalments continued to be filed at close to zero, based on prior years' modest results, right through the profitable year, which meant the corporation owed both the tax itself and, separately, interest on instalments that should have been paid throughout the year and were not.

When the first notice arrived, Dov had filed a relief request on the corporation's behalf, a short letter that asked CRA to cancel the interest because the profitable year had been unexpected. It was refused within weeks, a one-paragraph response noting that an increase in profit is not, on its own, a circumstance that justifies cancelling instalment interest. Dov told Gita and Prakash there was nothing more to be done and the corporation would need to pay the full amount.

It was the mortgage broker's comment about liens, months after that refusal, that pushed Gita to get a second opinion instead of simply paying the debt down slowly and hoping the refinance went smoothly anyway. What she was afraid of, in the end, was not the amount itself but losing control of the property at the exact moment they needed to touch its financing.

The legal question

Corporations that owe more than a modest amount of tax are required to pay instalments throughout the year, calculated using one of three methods: an estimate of the current year's tax, a figure based on the prior year's assessed tax, or a combination that bases the first instalment on the tax from two years earlier and the remaining instalments on the prior year's tax, whichever the corporation chooses to rely on. Instalments are generally due monthly, though an eligible small Canadian-controlled private corporation can pay quarterly instead, and a corporation with only a small amount of tax payable does not have to pay instalments at all. A corporation with a genuinely unpredictable income history, like a small rental property working through years of near break-even results, does not always know until well into the year, sometimes not until the year is over, that it will owe substantially more tax than the prior year suggested.

The legal question was not whether the corporation owed the tax itself; it did, and nobody disputed that. The question was whether the interest charged on the underpaid instalments should be cancelled or reduced under the discretion CRA holds to grant relief in circumstances beyond a taxpayer's control or where fairness otherwise justifies it. Dov's original request had framed the profitable year itself as the justification, which is exactly the argument CRA's refusal letter had already rejected: profit is not, by itself, an extraordinary circumstance.

The stronger question, the one Dov's request had not asked, was whether the corporation had acted reasonably once the shift in its financial position became apparent, and whether the size of the underpayment reflected genuine unpredictability rather than a corporation simply choosing not to adjust. A single tenant vacancy avoided and one mortgage renewal landing at a materially better rate, in the same year, is a specific and demonstrable combination of factors, not a vague claim that profit went up.

There was also the question of what already settled meant procedurally. CRA had refused the relief request once, and a second request covering exactly the same interest, on the same grounds, was unlikely to get a different reception from a reviewer who could see the earlier refusal in the file. Reopening the matter properly meant building a request substantial enough, with different and more specific reasoning, to be treated as a genuine second look rather than a repeat of an argument CRA had already turned down.

Answering that procedural question correctly mattered as much as the substantive one. A relief request that reads like the first one, only resubmitted, tends to get the same answer; one that identifies specifically what the first request got wrong, and supplies what it was missing, has a real chance of reaching a different reviewer's judgment.

What we did

1. Reviewed the refused relief request to understand exactly why it failed. We obtained a copy of Dov's original submission and CRA's refusal letter and found the request had made a single, general argument, that profit had increased unexpectedly, without any supporting detail about the specific events in that year or any indication the corporation had responded once the shift became clear. That gap was the starting point for everything we built afterward.
2. Reconstructed the year's specific financial events. We worked with Gita and Prakash to document the mortgage renewal, its timing and the rate change, along with the tenancy history showing no vacancy for the full year, both unusual for this property compared to its own history, and both things the corporation could not have known when it filed instalments at the start of the year. This gave the request concrete, dated events rather than a general claim about profitability.
3. Calculated what the corporation's instalments would have looked like under a reasonable, current-estimate approach. We showed that even a diligent corporation trying to estimate its current year's tax partway through would not reasonably have anticipated the full extent of the improvement until the mortgage renewal and the tenancy outcome were both known, which was well into the year, not at its start.
4. Addressed the prior refusal directly instead of ignoring it. Rather than submit a fresh request as though the first one had not happened, we referenced CRA's earlier refusal, acknowledged its reasoning was correct on the argument as originally framed, and explained specifically what additional facts and reasoning this request was bringing that the first one had not, so the reviewer would see it as a genuine second look rather than a repeat submission.
5. Separated the relief argument from any criticism of the accountant. We kept the request focused on the corporation's actual circumstances rather than framing it as Dov's mistake, since CRA's discretion turns on the taxpayer's situation, not on who prepared the earlier filing, and a request that reads as blame-shifting tends to land worse with a reviewer than one that simply makes its case.
6. Filed the reopened request with a full document package. We submitted the request with the mortgage renewal documentation, the tenancy record, and a clear instalment recalculation attached, giving the reviewing officer everything needed to assess the file in one pass, rather than a bare narrative that would have invited follow-up requests and added months to an already extended timeline. A complete package the first time also signalled that this was a serious, well-prepared second attempt rather than a repeat of the first.
7. Advised on the corporation's instalment process going forward. Independent of how the relief request turned out, we set up a mid-year instalment review for the corporation, tied to the rental roll and the mortgage renewal calendar, so that a future profitable year would be caught and adjusted for while it was happening, rather than discovered only when the following year's notice arrived and the same costly interest problem quietly repeated itself all over again.
8. Monitored the file and responded quickly when CRA requested clarification. When the reviewing officer asked for confirmation of the mortgage renewal date against the lender's records, we had the documentation ready the same week, which kept the reopened request moving instead of losing momentum the way a slow response, or a scramble to find an old mortgage statement, can invite.

The outcome

CRA reversed its earlier refusal. The reviewing officer accepted that the combination of the mortgage renewal and the uninterrupted tenancy represented a specific, demonstrable shift in the corporation's financial position that could not reasonably have been fully anticipated at the start of the year, and cancelled the large majority of the instalment interest, out of a combined underlying shortfall and compounded interest that had climbed to just over $130,000. A smaller portion, reflecting the period after the improved position became clear and before instalments were adjusted, remained payable, consistent with how this kind of relief is generally granted, and the corporation cleared that balance in full within a few months of the decision, from the same rental income that had caused the problem in the first place.

For Gita and Prakash, the practical fear that had started the whole process, the possibility of a lien complicating their refinance, never materialized. With the bulk of the debt cancelled and a payment plan in place for the remainder, their mortgage broker confirmed the refinance could proceed on schedule. The corporation's rental income, from the same profitable year that had triggered the problem, ended up funding the remaining balance within several months, without disrupting the family's own finances.

The file also closed a loop that had been left open by the first, badly handled request: Gita and Prakash now had a clear record of why the second submission succeeded where the first had failed, and an instalment review process that meant the corporation would not face the same surprise again if another strong year came along. Gita, who had been the one to push for a second opinion after the mortgage broker's comment, said afterward that the year of worry had been worse than the debt itself. Reopening a matter that had already been refused once is not always successful, but here the difference came down to specificity, not persistence alone.
