Illustrative example based on the kinds of matters we handle — not a specific client engagement; outcomes depend on the facts.
The situation
An owner-manager — the sole shareholder and director of a small operating company — came to us after a CRA audit of the corporation spilled over onto his personal return. The company owned an asset that he also used personally: think of a recreational property or vehicle held in the corporate name, paid for out of company funds but available to him outside business hours. He had assumed that because the company owned the asset and paid for it, the arrangement was simply a corporate matter.
The CRA saw it differently. After the audit, it issued a reassessment adding a shareholder benefit under subsection 15(1) of the Income Tax Act to his personal income — on the theory that the corporation had conferred a benefit on him by letting him use a corporate asset for personal purposes without paying for it. The benefit was large, taxed in his hands at full personal rates, with interest running back several years. The notice gave little explanation of how the number was built, and he could not see how personal use of one asset produced a benefit of that size.
The challenge
Subsection 15(1) is broad. Where a corporation confers a benefit on a shareholder, the value is included in the shareholder's income, and the CRA does not have to find a deliberate scheme to assess one. The pressure points are rarely about whether a benefit exists at all; they are about how the benefit is measured and how much of the use was genuinely personal.
- What is the correct measure of the benefit? The CRA will often reach for an easy figure — such as the corporation's full operating and ownership costs — rather than what the personal use was actually worth.
- How much of the use was business versus personal? If the asset has a real business purpose, the benefit should reflect only the personal portion, not the whole cost of holding it.
- Is there double counting? Capital, financing, and operating costs can overlap, and a benefit built by stacking every outlay can overstate the true advantage.
- Has a penalty crept in? Any penalty has to be defended on its own footing, separate from the underlying inclusion.
The real difficulty was evidentiary. The CRA's working number reflected one view of valuation; our task was to show, with records, that a more accurate measure produced a materially smaller benefit — ideally through the objection process, before a courtroom was needed.
How we approached it
We began with the thing clients tell us matters most: explaining, in plain terms, that a reassessment is the CRA's opening position, not a final verdict — and then setting out a written strategy. The work that followed was methodical rather than dramatic.
- Rebuilt the valuation. We separated the cost of owning the asset from the value of the shareholder's personal use of it, and tested the CRA's number against a more defensible measure.
- Documented genuine business use. We gathered records of the legitimate corporate purpose the asset served, so the personal-use portion could be isolated rather than treated as one hundred percent.
- Checked for overlap. We reviewed how operating, financing, and capital amounts had been combined, so the same dollars were not captured twice.
- Addressed any penalty separately. Where a gross negligence penalty is in play, we treat it as a distinct argument — the CRA carries the burden on penalties, and an honest, documented misunderstanding is very different from the conduct a penalty is meant to capture.
- Filed and argued the objection. We dealt with the CRA directly and advanced the position through a Notice of Objection, with a Tax Court of Canada appeal in reserve if it stalled.
Because the benefit surfaced out of a corporate audit, we kept the wider picture in view — coordinating with the company's audit representation so the personal and corporate files did not pull against each other, and watching for spillover into indirect-income theories like a net-worth audit.
The outcome
In matters of this kind, correcting the valuation and isolating genuine business use can substantially reduce the assessed shareholder benefit — because the inclusion should reflect the value of the personal advantage, not the entire cost of the corporation holding the asset. What can happen on objection is a smaller benefit, a recalculation of the related interest, and — where a penalty rested on conduct grounds that do not hold up — relief from that penalty as well. Some files resolve at the objection stage without the need to litigate.
It is equally honest to say these files take time. Valuations, document gathering, and back-and-forth with the CRA do not resolve overnight, and the result turns on what the records can prove.
The takeaway
For an owner-manager, a subsection 15(1) reassessment on personal use of a corporate asset is unsettling, but it is built on a measurement that can be tested. The strongest argument is usually not "there was no benefit" — it is "the benefit is worth far less than the CRA assumed." Pin the valuation to the true personal advantage, prove the legitimate business use, and strip out any double counting, and the amount the CRA can include often shrinks.
If you have been reassessed for a shareholder benefit, it helps to understand the mechanics early. Our guides on the shareholder benefit rules, the Youngman case on personal use of a corporate asset, and how to file a Notice of Objection explain how these assessments work and where they can be challenged. Owner-managers weighing how value comes out of a company may also find our note on salary versus dividends useful for future arrangements.
