The situation

Anong and her younger sister Pensri had always split the family's responsibilities along practical lines. Pensri had built and eventually sold a small distribution business, and after the sale she stepped back from working life. Anong, meanwhile, had spent two decades assembling a small portfolio of commercial buildings around Exeter, the kind of landlord tenants dealt with directly rather than through a management company. When Pensri's health made it difficult for her to keep a stable home for her teenage daughter Yaa, the two sisters did what the family had always done and simply adjusted. Yaa moved in with Anong, enrolled in the local school under her aunt's address, and stayed there through the rest of her teenage years.

Anong never married and had no children of her own, so for the years Yaa lived with her she claimed the eligible dependant credit, the provision that lets a single person supporting someone wholly dependent on them in their home claim roughly what a spousal claim would allow. She treated Yaa as her dependant in every practical sense: covering the household costs, signing school forms, listing her as an emergency contact. The claim had gone unquestioned for several years running.

The trouble started when CRA opened a broader audit of Anong's rental operations, looking at several years of income and expense reporting across her buildings, with adjustments under review in the mid six figures. It was a significant file on its own, the kind that ties up a landlord's attention for a year or more. Buried inside that larger review was a single line item: the eligible dependant credit for the year Yaa turned eighteen. The auditor's position was narrow but firm. Because Yaa was no longer a minor for part of that calendar year, the credit for that specific year did not apply, and CRA proposed to deny it outright rather than prorate or examine when the dependency actually ended.

What made the file harder to manage was timing. The original lawyer handling Anong's response to the broader audit withdrew from the file partway through for reasons unrelated to the case, leaving Anong holding a partially drafted response, a set of CRA correspondence with looming deadlines, and no clear record of what had already been argued. She came to our office needing someone to pick up a live file mid-stream, understand what had already been conceded or reserved, and finish the response before the window closed.

What the documents showed

The first task was reconstructing what the inherited file actually contained. Case files handed off mid-audit are rarely tidy: there were partial letters to CRA, a spreadsheet of rental adjustments with no clear version history, and correspondence referencing arguments that had apparently been raised verbally but never put in writing. Before anything could be argued on the dependant credit, we needed to know exactly what CRA had already been told and what still needed proving, and we spent the better part of two weeks simply cataloguing the file before drafting a single sentence in response.

Once the file was reassembled, the underlying facts were straightforward, and so was the law CRA had gotten wrong. The credit's age condition asks only whether the dependant was under eighteen at some point during the year, not whether they stayed under eighteen the full twelve months, and it is not a credit that gets prorated around a birthday. Because Yaa was still seventeen for part of the year in dispute, that condition was already satisfied in full. CRA's position, that turning eighteen partway through the year closed off the claim entirely, effectively read a proration into the credit that the legislation does not contain. The other half of the test still had to be proven on the facts: that Anong had actually maintained a home and supported Yaa in it while Yaa was still under eighteen, which is where the documentary record did its work. That Yaa went on living with Anong, still dependent on her, for the rest of that year was not itself what the credit required, but it made the household arrangement easy for an auditor to accept once the age argument was corrected.

The documentary record supported Anong's version of events cleanly. School records showed Yaa enrolled and attending through the full academic year under Anong's address, with no gap or transfer that would suggest a change in living arrangement. Bank statements showed no independent income for Yaa beyond occasional part-time work well below what would suggest self-support, and no rent payments, lease agreements or utility accounts in her own name anywhere in the year under review. Pensri's own records, including the documentation around her retirement and the sale of her business, corroborated why she was not in a position to maintain a separate household for her daughter that year, which mattered because CRA had also asked, informally, why the child's own mother was not the one claiming her.

We also went back through the broader rental reassessment that had swallowed the dependant issue as a side note, and found that several of the larger proposed adjustments rested on assumptions about expense categorization that the original file had not fully rebutted, particularly around repairs treated as capital improvements. Untangling the dependant credit from the rest of the audit meant addressing both pieces on their own terms, but the documentary picture for each pointed the same direction: a family arrangement that matched exactly what had been claimed on the returns, not a technical overreach dressed up as one.

What we did

  1. Audited the inherited file before responding to CRA. We read every letter, note and spreadsheet left by the previous lawyer to map what had been argued, conceded, or left open, because responding to an active CRA file without knowing its history risks contradicting a prior position or missing a deadline that had already been extended once, and a careless response at this stage can lock a client into a weaker position than the facts actually support.
  2. Requested an extension to properly assess the file. Given the mid-stream handoff, we asked CRA for additional time to prepare a complete response rather than filing something rushed and incomplete, explaining the change in representation clearly so the auditor understood the delay. This bought the weeks needed to gather records properly instead of guessing at what the prior lawyer intended to argue.
  3. Rebuilt the dependency record for the period that mattered. We gathered school enrollment records, Yaa's limited income history, and documentation of Pensri's circumstances that year, assembling a factual package that showed Anong had actually maintained a home and supported Yaa in it while Yaa was still under eighteen, because that support-and-residence fact, not the family's word alone, is what CRA auditors weigh most heavily against an assessment.
  4. Separated the dependant credit issue from the rental reassessment. The two matters had different evidentiary needs and different legal tests, and treating them as one undifferentiated dispute in the inherited file was diluting both arguments and slowing the whole review down. We split the response into two clearly organized submissions addressed to the same auditor so each issue could be assessed on its own merits without one weak point dragging the stronger argument down with it.
  5. Corrected the auditor's reading of the age condition. We wrote directly to the auditor's mid-year cutoff reasoning, showing that the credit's age test only has to be satisfied at some point during the year, not for all twelve months, and that nothing in the legislation prorates the credit around a birthday. We then backed that legal correction with the school and financial records proving the household side of the test for the months before Yaa turned eighteen.
  6. Addressed the rental income adjustments on their own merits. For the larger reassessment, we went through the expense categorizations the auditor had flagged, including several repairs treated as capital improvements, supplying invoices, lease documentation and contractor records that supported Anong's original filings and showed the work was routine maintenance rather than a capital upgrade, which reduced the size of the proposed adjustment considerably before any negotiation even began.
  7. Negotiated a combined resolution with the auditor. Once both pieces were properly documented, we proposed a resolution covering the full audit period in one settlement, avoiding a drawn-out formal objection process and giving Anong certainty across every year under review at once rather than fighting each year in sequence and leaving some issues unresolved while others dragged on behind them.
  8. Confirmed the settlement in writing before closing the file. We obtained written confirmation of the reassessed amounts for every year covered, checked the figures against Anong's own records line by line, and made sure nothing from the original, incomplete file lingered as an open item CRA could revisit later, since a file this disrupted by a mid-stream handoff needed a genuinely clean close, not just a verbal understanding.

The outcome

CRA agreed the eligible dependant credit should stand for the full year in dispute. The auditor accepted that the credit's age test is met once the dependant is under eighteen at any point in the year, not for the year as a whole, and dropped the mid-year cutoff position once that was set out plainly and backed by the documentary package showing Anong had actually supported Yaa in her home through that period, closing what had been the most emotionally charged item in the file for Anong personally.

The broader rental reassessment resolved on materially better terms than the file's condition had suggested was possible when Anong first came to us. Several of the larger proposed adjustments were reduced once proper documentation was supplied, and the final settlement across all the years under review landed well below the original proposed figure, though not at zero; a handful of smaller expense items were still recharacterized as the auditor had proposed, and Anong accepted those rather than litigate a modest amount further when the larger issues had already been resolved in her favour.

For Anong, the practical result was that the credit she had claimed in good faith for raising her niece was recognized as correct, and a rental audit that had grown unwieldy under a change of counsel was brought to a defined close instead of dragging into a formal objection process that could have taken another year or more. The family arrangement that had prompted the claim in the first place was never really in question; it just needed to be documented properly and argued on the right legal test rather than left half-finished in a transitioning file.

Pensri and Yaa were not directly involved in the CRA correspondence, but the resolution mattered to them too. The dispute had, for a period, cast doubt on whether the household arrangement the family had built around Yaa's teenage years would hold up to scrutiny, and having it confirmed in writing closed that question for good.

What you can learn from this

  • A dependant turning eighteen partway through the year does not end eligibility for the credit for that year; the age test only has to be met at some point in the year, and the credit is not prorated around the birthday.
  • When you inherit a file mid-audit, ask for time to reconstruct what has already been argued before filing anything further; responding blind can undercut positions already taken.
  • School records, bank statements and a clear account of why a parent could not maintain a household are the kind of ordinary documents that prove a dependency claim.
  • A single credit dispute buried inside a larger audit deserves its own evidentiary package rather than being argued as an afterthought to the bigger issue.
  • Settling several years of a reassessment together, once the facts are properly documented, can be faster and less costly than fighting each year separately.
