A Partial Reassessment That Undid Its Own Case

The situation

The letter arrived in late winter, and it was not the letter Keisha expected. She had claimed the medical expense tax credit for the private in-home nursing care she paid for on behalf of her mother, Lusine, who had been managing a slow decline in mobility for two years. The reassessment did not deny the claim outright. It disallowed roughly a third of the amount and left the rest standing, with a short explanation that some of the invoices did not clearly separate nursing services from what the reviewer called general household assistance.

Keisha ran a small bookkeeping practice from home, which meant her own income was modest and irregular, and the credit had mattered to her that year more than usual. Her brother, Andre, worked as a grocery clerk and had helped cover some of the nursing costs directly, paying certain invoices from his own account while Keisha handled the rest and claimed the credit on her return, since she was the one who had arranged the care and kept the paperwork. Lusine's late husband had been a forklift operator for decades before he passed, and the household had never had much cushion to draw on when her mobility began to decline. The in-home nurse came four mornings a week to help with bathing, mobility exercises, and medication, work that Keisha and Andre could not manage alone around their own jobs and their own households.

What struck Keisha first was not the dollar amount, which sat under fifteen thousand dollars in total, but the specificity of the partial disallowance. If the reviewer thought the whole arrangement was suspect, why accept two thirds of it and only question the rest? That selectivity felt strange to her, almost arbitrary, and it was the detail that made her decide to push back rather than simply accept the reduced credit and move on with her year. She brought the letter to us within the week, along with a folder of invoices, bank records, and a handwritten log she had kept of the nurse's visits since the arrangement began.

Our first read of the reassessment was that the reviewer had drawn a line through the invoices based on wording alone, not on what the services actually were. The nurse's own invoices used generic language like 'care visit' and 'assistance,' phrases that could describe almost anything from bathing support to light housekeeping, and someone processing the file quickly had apparently split the claim down the middle of that ambiguity rather than asking for clarification from Keisha directly. That gap between what the paperwork said and what had actually happened in Lusine's home was where the file's turning point sat, and it was not a gap either Keisha or the nurse had thought to close at the time the invoices were written.

What the review found

The eligibility rules for medical expenses under the Income Tax Act allow a credit for amounts paid for attendant care and certain nursing services, but the rules draw a real distinction between care that addresses a medical or functional need and ordinary household help like cleaning or cooking. That distinction matters, and it is also where a lot of claims run into trouble, because home care invoices are often written in plain language by caregivers who are not thinking about tax categories when they bill a family for a month of visits.

When we went through the invoices line by line against Lusine's own medical file, a pattern emerged that neither Keisha nor the nurse had noticed while the care was actually happening. The disallowed portion corresponded almost exactly to visits where the invoice description was thinnest, usually just 'care visit, 3 hours,' with no further detail about what the visit involved. The accepted portion happened to align with invoices where the nurse had, for whatever reason on a given week, written a fuller note describing bathing assistance, mobility support, or medication administration. The reviewer had not actually assessed the substance of the care in each visit. They had assessed the wording of the paperwork sitting in front of them, and where the wording was vague, they had assumed the least generous explanation available.

That was useful to know, but it was also a warning about how far a documentation argument alone could take the file. The reviewer's approach meant that simply asserting the disallowed visits were medical in nature would not be enough on its own, because the same thin invoices that had triggered the disallowance in the first place would still be sitting unchanged in the file if we submitted nothing new. We needed something independent of the nurse's own invoices to establish what those specific visits actually involved, ideally from a source with more medical authority than a caregiver's billing notes.

We also found a smaller problem buried in the file that had nothing to do with invoice wording at all. A handful of the disallowed invoices had been paid by Andre directly from his own bank account, not by Keisha, and yet the entire credit had been claimed on Keisha's return alone. The rules generally require the person claiming the credit to be the one who actually paid the expense. That condition falls away between spouses or common-law partners, where an expense paid by either one can be claimed by either of them, but Keisha and Andre were siblings, not a couple, so that exception did nothing for them, and the mixed payment pattern between them had never been sorted out clearly when the return was filed. That was a real structural gap, not a wording misunderstanding, and it meant part of the disallowance was never going to be reversible, no matter how well documented the underlying nursing care turned out to be once we dug into it.

What we did

1. Reconstructed the care record from Lusine's own medical file. We asked Lusine's family physician for a letter describing the nature and frequency of the in-home nursing care over the period in question, since a treating physician's account of an ongoing mobility decline carries considerably more weight with a reviewer than a caregiver's invoice wording, and it could speak directly to whether the disputed visits addressed a medical need rather than general household help.
2. Matched the physician's letter against each disputed invoice, visit by visit. We built a simple table lining up every disallowed visit date against the physician's description of Lusine's needs during that window, so the reviewer could see clearly that the thin invoice wording described exactly the same underlying care as the fuller invoices from the same nurse that had already been accepted without dispute.
3. Separated the payment issue from the description issue early in the file. We went back through Keisha and Andre's bank records to identify precisely which invoices Andre had paid directly from his own account, and confirmed that Andre had not separately claimed any medical expense credit himself, since an expense he had actually paid needed to be addressed honestly rather than quietly folded into Keisha's argument.
4. Advised Keisha plainly that the Andre-paid invoices were unlikely to be recoverable on her return. We explained that the credit generally has to follow who actually paid the expense, and that no amount of medical documentation would fix a claim made by the wrong family member, so we chose not to spend the file's limited credibility contesting a portion we were unlikely to win.
5. Prepared a written response focused only on the winnable portion of the claim. We drafted a submission addressing solely the invoices Keisha had paid herself, where the vague description was the only real obstacle standing between the reviewer and acceptance, attaching the physician's letter and the visit-matching table as the core supporting evidence, and keeping the covering explanation short enough that the documentary evidence, not our argument, carried the file.
6. Requested reconsideration of the specific disputed line items, not the whole assessment. Rather than asking for a full re-review, which risked reopening the two thirds of the claim the reviewer had already accepted without complaint, we asked narrowly for reconsideration of only the disallowed invoices tied to Keisha's own payments, keeping the exposure of the request as contained as the evidence allowed.
7. Kept Keisha informed of the realistic range of outcomes throughout the process. Because part of the original claim was clearly not coming back once the payment records were reviewed, we made sure Keisha understood early on what the likely floor and ceiling of the outcome looked like, so the eventual result read as an expected resolution rather than a surprise or an unexplained loss, and so she could plan the following year's arrangement around that lesson instead of repeating the same mixed-payment pattern.

The outcome

The reviewer accepted the physician's letter and the visit-matching table as sufficient to reclassify most of the invoices Keisha had paid herself, restoring a meaningful portion of the disallowed credit to her return. The invoices Andre had paid directly, however, stayed disallowed on Keisha's return, exactly as we had told her to expect from the moment we found the payment mismatch in the bank records. That portion amounted to a real loss, in the low thousands of dollars, and there was no argument available to recover it once the payment record made it clear that Andre, not Keisha, had actually paid for that share of the care.

The net result was a partial win dressed as a partial loss, or the reverse, depending on how you look at it. Keisha kept most of the credit she had originally claimed, and the physician's letter turned out to carry more weight with the reviewer than either of them expected. But she also came away understanding something she had not fully appreciated before the letter arrived: when two family members split the cost of a parent's care between two different bank accounts, the tax credit has to follow the actual payments, not just whoever happens to keep the folder of receipts and files the return.

For the following tax year, Keisha and Andre agreed on a cleaner arrangement, with Keisha paying the full cost of care from a dedicated account set up for that purpose and Andre reimbursing her separately outside of any invoice paper trail, so that a single, clearly documented payer would be claiming the credit going forward without any ambiguity for a future reviewer to seize on. The reassessment's own selective wording, which had accidentally shown us exactly where the reviewer's reasoning was thin and where it was not, ended up mattering more to the eventual outcome than any argument we could have built entirely from scratch.
