The situation

Dov ran a one-person electrical contracting business out of Windsor, incorporated a few years earlier on his accountant's advice once his contract work outgrew a sole proprietorship. He took on jobs directly from homeowners and general contractors, invoiced through the corporation, and paid himself a modest salary along with periodic draws he understood to be repayments of money he had personally loaned the company to buy tools, a van, and cover slow months between contracts. Some months the corporation had more work than it could handle; other months, especially over winter, Dov picked up short-term jobs through app-based trades platforms under his own name to keep income steady, which meant his personal and corporate finances brushed up against each other more than a typical incorporated business owner's would.

His spouse, Eitan, an elementary school teacher, had no role in the business but filed a joint household return with him each year, and their combined income sat comfortably in the middle range for the region. The corporation's books were kept by a part-time bookkeeper, Selam, who worked for several small trades businesses around Windsor and handled Dov's monthly reconciliations along with basic HST filings. For two years, the arrangement worked well enough on the surface, even if the underlying records were thinner than they should have been. Then the Canada Revenue Agency selected the corporation for a business audit — a routine-looking review that asked for bank statements, invoices, and the general ledger going back three years.

What the audit found

Partway through the review, the file changed character. The auditor flagged a pattern of transfers from the corporation's bank account to Dov's personal account that did not match any invoice, payroll entry, or documented loan agreement in the bookkeeping file. Selam had recorded many of these transfers simply as "owner draw" or left them uncoded entirely, without linking them to the loan Dov had actually made to the company when it was starting out. A smaller number of transfers were reimbursements for materials Dov had bought personally on job sites and never formally invoiced back to the corporation, which added another layer of confusion to an already thin paper trail.

Under the Income Tax Act, when a corporation confers a benefit on a shareholder — money or value that flows to them personally without being salary, a dividend, or the repayment of a genuine debt the shareholder is owed — that benefit is treated as taxable income to the shareholder in the year it is received. This rule exists because a shareholder could otherwise strip value out of a corporation tax-free by simply calling every withdrawal something other than income. The auditor's working theory was that Dov had been quietly draining the corporation for personal use and calling it something else at tax time. Based on the unexplained transfers, the CRA proposed to add roughly $118,000 to Dov's personal income across the two audited years, which would have produced a substantial personal tax bill along with arrears interest, on top of whatever the corporation itself might separately owe for understated income or disallowed expenses.

Dov's accountant had prepared the original filings but was not equipped to argue the audit itself, and by the time Dov called Treadstone Law, the CRA had already issued a proposal letter setting a firm deadline to respond before the reassessment became final. Eitan, worried about what a five-figure personal tax bill would mean for their household on top of a teacher's salary, sat in on the first call.

What we did

  1. Requested the full audit working papers. Before responding to anything, our team asked the CRA for the specific transfers it had flagged and the reasoning behind each one. This turned a vague accusation of "undeclared benefits" into a finite, transaction-by-transaction list that could actually be answered.
  2. Rebuilt the loan account from source documents. Years earlier, Dov had advanced funds to the corporation to buy his van and initial tool inventory, but the paperwork evidencing that loan had never been formally recorded on the books. We gathered his personal bank statements, the original purchase receipts, and email correspondence with his accountant from that period to reconstruct a shareholder loan account showing what he was owed and when.
  3. Matched each flagged transfer to a business purpose. Working through the ledger line by line, we categorized every disputed transfer as either a repayment against the reconstructed loan, a reimbursement for materials Dov had paid for out of pocket, or ordinary salary already reported on his T4 slip. A handful of transfers turned out to be genuinely undocumented and could not be explained — we did not try to paper over those.
  4. Prepared a formal written response with a reconciliation schedule. Rather than arguing informally with the auditor, we submitted a structured schedule mapping every transfer to its supporting evidence, along with a short written explanation of the loan history and why the bookkeeper's coding had misrepresented the underlying transactions.
  5. Addressed the unexplained portion directly. For the small number of transfers that genuinely lacked documentation — worth a modest fraction of the total in dispute — we advised Dov to accept those as taxable benefits rather than contest them, which preserved credibility on the much larger, well-documented balance of the file.
  6. Corresponded with the CRA through the objection process. When the auditor did not fully accept the first response, we filed a formal notice of objection, which triggers an independent review by the CRA's appeals division separate from the original auditor, and continued supplying supporting detail as it was requested.

The outcome

The appeals officer who reviewed the objection accepted the reconstructed shareholder loan account and the documentation behind it. Of the roughly $118,000 originally proposed as a taxable benefit, the CRA withdrew its position on all but a small undocumented portion, worth well under $10,000, which Dov paid along with modest interest rather than continuing to dispute it. The bulk of the reassessment was reversed, and Dov's personal tax bill returned close to what it would have been without the audit ever happening, aside from that small conceded amount and the arrears interest attached to it.

The process took the better part of a year from the initial audit letter to the final decision on objection, which is typical for a file that moves from audit into formal dispute rather than being resolved at the audit stage alone. Dov also switched bookkeepers and, on our recommendation, had a proper shareholder loan agreement drafted and the loan account formally recorded going forward, with every draw and repayment coded against it as it happens rather than sorted out months or years later. Eitan, who had never dealt with a CRA dispute before, said afterward that the hardest part was not the money but the uncertainty of not knowing for months whether the larger number or the smaller one would end up being real.

What you can learn from this

  • If you lend your own corporation money, document it as a shareholder loan from day one — a written agreement and a running ledger balance are far easier to produce than reconstructing years of transfers after an audit begins.
  • Bookkeeping shortcuts like generic 'owner draw' entries create exactly the ambiguity the CRA is trained to flag. Every transfer between a corporation and its shareholder should be coded to what it actually is.
  • A CRA proposal letter is not final. Requesting the underlying working papers and responding through the formal audit and objection process, rather than arguing informally, gives you a real chance to correct the record.
  • Conceding the parts of a file you genuinely cannot document strengthens your position on the parts you can — auditors and appeals officers respond better to selective, evidence-backed pushback than to blanket denial.
  • A business audit of your corporation can become a personal tax problem for you as the shareholder. Treat any CRA request touching your corporation's books as something that may affect your own return, not just the company's.
