An audit reassigned after months of unanswered documents

The reassessment on the table was close to nine hundred thousand dollars. The bigger problem was that the auditor handling the file had stopped responding months earlier.

The situation

The number on the proposal letter was eight hundred and sixty thousand dollars. That was the reassessment the tax authority was proposing against Teresa's manufacturing business, built up over three audited years, and it was the figure Teresa read aloud to Sandro across the kitchen table the night it arrived, because saying it out loud was the only way either of them could process it.

Teresa had built the business from nothing over almost two decades, a small manufacturing operation based near Haliburton that made specialized parts for equipment suppliers, run with a handful of employees and margins that did not leave much room to absorb a surprise of this size. Sandro, her co-owner, had spent his earlier career as a technology executive and had brought a set of inventory and costing systems into the business that were more sophisticated than what a company of its size usually ran, on the theory that better data would prevent exactly the kind of dispute they were now facing. The audit, when it started, focused on how the company had classified certain input costs and inventory adjustments across three fiscal years, and the auditor's working theory was that a significant portion of what the company had treated as ordinary cost of goods sold should instead have been capitalized, which would have shifted the timing of deductions and, in the auditor's calculation, produced a large amount of understated income.

For the first several months, Teresa's existing accountant, Dewi, responded to information requests as they came in, sending spreadsheets and supporting invoices whenever the auditor asked for them. Then the requests slowed, replies from the auditor grew sparser, and at a certain point they stopped altogether. Documents Dewi had submitted went unacknowledged. Phone calls were not returned, and voicemails referencing specific document dates got no reply at all. A proposal letter eventually arrived anyway, built on the auditor's earlier working file, without any indication that the more recent submissions had been reviewed or even received.

Dewi, competent with routine filings but out of his depth on a dispute of this size, told Teresa the number was likely accurate and she should prepare to pay it, reasoning that the tax authority would not propose a figure that large without a solid basis. Sandro, with a business background that made him distrust a number nobody could walk him through line by line, insisted they get a second opinion before accepting that. That disagreement is what brought Teresa to our office.

The gap nobody had noticed

Before anything else, we needed to understand whether the eight hundred and sixty thousand dollar figure was defensible on its own terms, separate from the question of whether the audit process had been handled fairly. Those are two different problems, and conflating them is a common mistake: a taxpayer with a legitimate fairness complaint can still owe real money, and a taxpayer treated fairly can still be facing a wrong number. Chasing only one of those two threads, and assuming the other would sort itself out, is how a case like this can end up either overpaying to make a fairness problem go away or winning a procedural point while the actual dollar figure stays wrong.

We started by reconstructing the company's cost accounting from source documents, rather than relying on either the company's own summaries or the auditor's working papers, because both had been built on assumptions that turned out not to match how the business actually operated. The gap we found was specific: a portion of what looked, from the outside, like inventory-related capital expenditure was in fact recurring maintenance and retooling cost on existing equipment, a category the accounting records had not clearly separated from the acquisition of new production assets. Nobody, not the company's own bookkeeper over the years, not Dewi, and not the auditor, had gone back to source invoices to draw that line properly. Everyone had worked from the same ambiguous summary categories and drawn different conclusions from them, each one plausible in isolation and each one wrong in a different direction.

Once we separated the two categories using the underlying invoices, roughly two-thirds of the auditor's proposed adjustment lost its factual basis. The remaining third reflected a genuine, if narrower, disagreement about the timing of a smaller set of costs that plausibly should have been capitalized, and we told Teresa and Sandro directly that this portion had real substance and was not going to disappear on review, however the fairness question was resolved. Being candid about that early mattered: a client who hears only the good news from the accounting review is a client who feels blindsided later when the settlement is not a full reversal.

The second problem, separate from the numbers, was the process itself. The tax authority's own practice is to issue a proposal letter and give the taxpayer a defined period to respond, with representations made in that window meant to be weighed before the file moves forward. Months of unanswered submissions and an unresponsive auditor is not just frustrating, it is a procedural fairness issue precisely because that response window was never honoured: submissions kept going in and nothing came back. That is a different argument from claiming a reassessment is invalid because an audit moved too fast or worked from an incomplete file — that claim belongs in a notice of objection, where the evidence gets a fresh look from a different part of the agency. But no reassessment had been finalized here; the file was still sitting on a stale proposal, unanswered, which was the fairness problem worth raising before it ever got that far. We documented the timeline of submissions and non-responses carefully, because a fairness complaint without a clear record is just a complaint, while one with dates, tracking confirmations, and unanswered follow-ups is something a reviewing office has to take seriously. The distinction is not cosmetic: a vague grievance can be set aside, but a dated log of ignored correspondence is close to impossible for an internal review to wave away.

What we did

  1. Reconstructed the disputed cost categories from original invoices, purchase orders, and equipment maintenance logs rather than relying on the company's existing summary ledgers, because those summaries were themselves the source of the ambiguity that had misled both Dewi and the auditor in opposite directions, and only the underlying paperwork, item by item, could settle which category a given cost actually belonged in and why.
  2. Documented the full communication timeline with the audit division, listing every submission the company had made, its date, the method it was sent by, and the response or absence of one, to establish objectively, with dates and delivery confirmations rather than memory, that the file had gone unattended for an extended period despite months of good-faith cooperation from the company's side of the file.
  3. Filed a formal fairness complaint with the Office of the Taxpayers' Ombudsperson, setting out the documented pattern of unanswered submissions in plain terms and asking the office to investigate why the file had gone unattended, since the ombudsperson does not decide tax amounts but does have standing to push a stalled file back into motion, and continuing to submit material into an unresponsive file was clearly not going to change anything on its own, no matter how thorough the next submission was.
  4. Secured reassignment of the file to a new auditor within the division once the ombudsperson's office accepted the complaint for investigation, which reopened the door to a substantive review of the material we had already reconstructed, rather than leaving the case to drift indefinitely on the original auditor's incomplete and outdated working file while interest continued to accrue on a number nobody had actually tested against the source documents.
  5. Presented the rebuilt cost analysis to the new auditor with a clear line-by-line reconciliation showing which costs were properly expensed as maintenance and which represented a genuine timing question around capitalization, framing the smaller remaining issue honestly rather than disputing every dollar of the original proposal out of principle, which we judged would cost the file credibility it badly needed at that stage.
  6. Negotiated the treatment of the remaining adjustment over several meetings, arguing for a shorter capitalization period than the audit division initially proposed, on the basis that the specific equipment involved had a demonstrably shorter useful life than the division's standard assumption allowed for, supported by manufacturer specifications and Sandro's own maintenance records for each affected machine.
  7. Confirmed the settlement terms in writing before Teresa and Sandro accepted them, including the revised assessment amount, the interest calculation and the exact period it covered, and explicit confirmation that the earlier years under review would not be reopened later on other grounds once this file closed, so the business could finally plan around a number it knew was final.

The outcome

The file settled at roughly one hundred and ninety thousand dollars, against the original proposal of eight hundred and sixty thousand. That final figure reflected the genuine timing adjustment on the smaller category of costs, plus interest calculated from when those amounts would originally have been due had they been capitalized correctly from the start rather than expensed as ordinary maintenance. It was a real cost to the business, not a symbolic one, and Teresa and Sandro paid it as a negotiated compromise rather than a vindication of everything they had argued.

The fairness complaint achieved something the numbers alone could not have: it got a stalled file moving again after months of silence. Without the reassignment, there was no clear path to getting the reconstructed accounting actually reviewed, since the original auditor's file had effectively stopped progressing regardless of what was submitted to it. The complaint did not itself determine the dollar outcome; what it did was create the conditions where the outcome could finally be argued on the merits, in front of someone willing to look at the evidence.

Teresa has since separated maintenance and retooling costs from capital equipment acquisitions in the company's chart of accounts, a change that took an afternoon with the bookkeeper and closes the exact gap that produced three years of ambiguity in the first place. Sandro, whose insistence on a second opinion had been the reason the file was reopened at all, now reviews the company's quarterly cost classifications personally alongside the bookkeeper, a habit born directly out of watching how much a single blurred accounting line had nearly cost the business.

Neither Teresa nor Sandro came away describing the result as a win in the way an outright reversal would have felt. What they got instead was an accurate number, arrived at through a process that finally worked the way it was supposed to, after a period where it plainly had not.

What you can learn from this

  • A stalled or unresponsive audit file is a fairness problem on its own, separate from whether the proposed number is accurate, and it can be raised as a formal complaint even before the numbers are resolved.
  • Ambiguous accounting categories, like blending maintenance costs with capital equipment purchases, can drive a large reassessment even when nobody involved is acting in bad faith.
  • Reconstructing figures from original source documents, rather than trusting existing summaries from either side, is often the only way to find where a dispute actually went wrong.
  • A negotiated settlement that concedes part of the original claim is not a loss if the conceded part reflects a genuine issue; the goal is an accurate number, not a clean sweep.
  • Fix the accounting practice that caused the ambiguity once you find it. The audit ends, but a badly organized chart of accounts will keep generating the same argument every time someone looks.
