Collapsing a two-tier corporate group after years away

The situation

The letter from the tax authority arrived while Min-ji was trying to figure out why a company she barely remembered owed money. The company, a numbered subsidiary that had not issued an invoice in six years, was flagged for a compliance review, and the review had turned up an amount in dispute that fell somewhere between fifteen and fifty thousand dollars once penalties and interest were added in.

The structure went back further than that. Before Min-ji left Canada for several years to work overseas, an accountant named Dragan had set up two connected companies for her small consulting business, which advised local daycares on program design and imported specialty learning toys. The plan at the time involved splitting income between a parent company and a subsidiary for reasons that, as far as Min-ji could reconstruct years later, related to a tax advantage that never actually materialized. She left the country not long after incorporation, and her spouse Sung-min, a letter carrier with no background in corporate filings, kept both companies technically alive by paying an outside bookkeeper to file blank returns.

By the time Min-ji came back to Canada and resumed running the business herself, the subsidiary had no employees, no assets beyond a small bank balance, and no purpose. But it still had to file every year, it still generated its own notices of assessment, and because income and losses had been allocated unevenly between the two companies over the years, the compliance review treated the group's reporting as inconsistent rather than simply outdated.

Min-ji's income from the consulting business was modest, and the business itself was the household's main source of stability. She could not close it down while the dispute was sorted out, because the daycare clients who relied on her program reviews needed continuity, and a gap in service would have meant losing them permanently.

What made the letter especially unsettling was how little it matched Min-ji's own sense of the business. She thought of herself as running one small operation, a person who reviewed daycare programs and brought in learning toys parents and educators could not easily find elsewhere. She had never thought of herself as running a group of companies with obligations that could grow while she was not paying attention. The subsidiary had been Dragan's idea, adopted before she left the country and never revisited once she was gone, and by the time it resurfaced as a live problem, the original reasoning behind it barely mattered anymore. What mattered was that it existed, that it had filed returns every year on autopilot, and that those returns were now being read as evidence of something they were never meant to represent.

The problem

The compliance review had identified what looked like a mismatch: income reported by the parent in some years appeared, on paper, to belong to the subsidiary, and vice versa. This was not a case of hidden income. It was the residue of a structure that had never been used the way it was designed, run for years by someone with no reason to question what an outside bookkeeper filed on autopilot.

The tax authority's position, at least initially, was that the two companies had to be treated as separate taxpayers with their own obligations, and that any shortfall in one company could not simply be offset against an overpayment in the other. Under that reading, Min-ji risked paying tax twice on income that, in substance, had only been earned once.

Meanwhile, the subsidiary's continued existence was itself part of the problem. Every year it stayed open, it generated another return, another filing deadline, and another opportunity for the same kind of inconsistency to repeat. Fixing the specific dispute without addressing the structure would have meant solving the same problem again within a year or two.

There was also a practical constraint layered on top of the legal one. The consulting business could not pause while any of this was worked out. Min-ji still had daycare clients booking program reviews, still had toy import shipments arriving on schedule, and still needed to invoice and collect payment through whichever company was, at any given moment, the one doing the work. Any fix had to happen around a functioning business, not instead of one.

The underlying question was whether the group's history could be reconciled well enough to satisfy the reviewer that no income had actually escaped tax, and whether the structure itself could be simplified so the same confusion could not recur.

There was a real risk that the two questions would pull in opposite directions. Winding up the subsidiary too quickly, before the dispute over past years was settled, could look to a reviewer like an attempt to move assets out of reach before an assessment landed, even though that was never the intent. But leaving the structure untouched while the dispute dragged on meant another filing deadline would arrive for a company that everyone agreed served no purpose, adding a ninth year of pointless paperwork on top of the six already under review. The two pieces of the file, the historical dispute and the structural fix, needed to move in a sequence that made both look like what they actually were: a genuine cleanup of an old mistake, not a reaction to getting caught.

What we did

1. Reconstructed six years of intercompany activity from bank records, old bookkeeper files, and whatever original incorporation paperwork Dragan had kept, since Min-ji herself had been out of the country for most of the period and could not testify from memory to how income had actually moved between the two companies, and the outside bookkeeper who had filed the returns had since moved on and left only partial notes behind.
2. Mapped every dollar reported by each company against where the underlying work had actually been performed, comparing invoices and bank deposits against which company had, in reality, delivered the daycare program review or shipped the toy order behind each figure. That comparison showed the split between parent and subsidiary had never matched real activity and existed only on the bookkeeper's spreadsheets, a distinction that mattered because it meant no income had genuinely gone unreported, only misfiled.
3. Prepared a submission to the reviewer explaining the group's history, framing the mismatch as a bookkeeping artifact from a structure that had never been used as designed, rather than an attempt to shift income between entities to reduce tax owed. The submission leaned on the reconstructed records rather than Min-ji's own account of events, since she had been out of the country for most of the period and a reviewer weighing a misrepresentation allegation needs documents, not a client's memory of what an accountant told her years earlier.
4. Requested that the reviewer reassess each company individually to reflect where the income had actually been earned, since Canadian tax law has no mechanism for taxing related corporations on a combined basis; each remains its own taxpayer. The argument instead was that the shortfall found in one company and the overpayment in the other were two halves of the same bookkeeping error, so correcting each return to match where the work was actually performed would eliminate the mismatch without inventing group-level relief that does not exist in law.
5. Prepared the statutory wind-up of the subsidiary into the parent once the reassessment request was filed, deliberately not before, so the timing could not be read as an attempt to move assets out of reach ahead of an assessment. A formal wind-up was chosen over a simple deregistration because it preserved the subsidiary's tax attributes and rolled its remaining assets into the parent without triggering a taxable disposition, which a straight closure of the company would not have avoided.
6. Sequenced the wind-up around the business's operating calendar, timing the transfer of contracts, the small bank balance, and the subsidiary's registrations so that invoicing continued without interruption. This mattered because Min-ji could not simply pause the consulting business while the corporate structure was fixed around it; daycare clients booking program reviews and toy shipments arriving on schedule needed a company on the other end of every invoice at all times, so the transfer had to land between billing cycles rather than during one.
7. Notified the tax authority of the wind-up separately from the dispute, rather than folding the news into the reassessment submission, so the reviewer could see the structural fix was happening regardless of how the reassessment turned out. That separation mattered: a wind-up that only appeared once the reassessment argument looked likely to succeed could read as an attempt to make the problem disappear procedurally, while one announced on its own timeline read as exactly what it was, a genuine cleanup of an old mistake.
8. Followed the file through to a final reassessment rather than treating the reviewer's informal agreement as the end of the matter, since a verbal or preliminary acceptance carries no weight if the file is ever looked at again later. We confirmed in writing that the corrected, entity-by-entity allocation had been accepted, and only then closed out the subsidiary's last return, so there was a documented record Min-ji could point to if the same years were ever questioned again.
9. Reviewed the parent company's own filings for the same years to confirm the corrected figures reconciled cleanly once the subsidiary's history was folded in, checking that nothing had been double-counted or left out in the process of moving income between the two returns. This step existed so that a second reviewer looking at the parent alone in a future year, with no memory of this dispute, would not find a new discrepancy created by the fix itself.
10. Walked Min-ji and Sung-min through what to expect from the reviewer going forward, since neither of them had dealt with a compliance review before. We explained which follow-up requests would be routine administrative confirmations they could handle themselves, and which, if they arrived instead, would signal the file was not actually closed and needed to come straight back to us rather than being answered informally, so a stray reply would not undo the record the submission had just built.

The outcome

The tax authority accepted the corrected, entity-by-entity allocation. The reassessment eliminated the double-counting, and the amount actually owed came in well below the original figure identified in the compliance review, with the penalty portion removed entirely once the reviewer agreed the mismatch reflected bookkeeping history rather than any attempt to understate income.

The wind-up closed the subsidiary permanently, folding its remaining assets and its small client contracts into the parent company. Min-ji now files one corporate return instead of two, and the consulting business kept operating through the entire process without a gap in service. No client contract lapsed, and no invoice went unpaid during the months the file was open.

The result was a clean structural fix layered on top of a resolved dispute, rather than either one alone. Min-ji later said the more lasting relief was not the reassessment number but no longer wondering, every filing season, what the second company was actually for.

That continuity was not incidental; it was a deliberate condition of how the wind-up was sequenced, and it mattered as much to Min-ji as the tax outcome itself, since a business built on ongoing relationships with daycares does not easily recover from an unexplained gap in service.

Sung-min, who had kept both companies alive for years without fully understanding why they existed, described the resolution as the first time the paperwork actually made sense to him. Going forward, the household deals with one company, one filing deadline, and one set of records, which on its own removes a source of risk that had been sitting quietly in the background since before Min-ji ever left the country.
