A tax reassessment that blew through the cap because tax was never a fundamental rep

The situation

A four-location specialty retail chain in British Columbia was sold on a share basis for $2,500,000. The purchase agreement's indemnity structure followed the standard two-tier design: general representations — financial statements, material contracts, employees, tax, compliance with law — subject to an indemnity basket and a 15% indemnity cap of $375,000, and a short list of “Fundamental Representations” carved out of both. The defined list covered organization and good standing, authority to enter the agreement, title to the purchased shares, and capitalization — the representations that go to whether the seller actually owned and could sell what it was selling.

Tax representations sat in the general category, subject to the 15% cap like every other operational representation. Nobody on either side raised, during negotiation, whether tax exposure was severe enough to warrant its own carve-out; the fundamental list was negotiated primarily around ownership and authority, and tax was never part of that conversation.

The problem

Fourteen months after closing, the Canada Revenue Agency reassessed the target for unremitted payroll source deductions and uncollected HST across the three fiscal years preceding the sale, arising from a payroll-classification error the seller's own bookkeeper had made and never corrected. With penalties and interest, the reassessment totalled $540,000 — well above the $375,000 general cap, and more than twice the deal's basket.

The buyer's counsel argued that a reassessment this severe went to the basic value of the business it had bought, not to a routine operational risk, and should be treated as functionally fundamental even though the tax representation was not on the defined list. The seller's counsel disagreed: the agreement defined “Fundamental Representations” as a specific, closed list of clauses by section number, and the tax representation's section was not among them.

The rule that decided it

No statute, in Canada or anywhere else, dictates which representations in a business purchase agreement must be treated as fundamental. Treadstone Law's comparison of fundamental and general representations in an Ontario business sale states the point without qualification: “There is no fixed rule in Ontario law dictating exactly how a cap or survival period must be structured for either category — these are negotiated contract terms that vary from deal to deal.” The same guidance describes how the two categories are typically treated once they are defined: fundamental representations are “often carved out of the general cap, sometimes tied to the full purchase price,” while general representations are “usually subject to a negotiated cap and a minimum claim threshold.” Which category a given representation falls into is not a legal question at all — it is only ever a drafting one.

That is precisely why the tax representation's absence from the fundamental list controlled. The agreement's defined term was a closed list, not an open standard inviting a court or arbitrator to ask whether a particular breach felt fundamental in hindsight. Severity of loss and category of representation are two different questions, and only the second one the cap actually asks. A $540,000 reassessment is severe by any measure; it is not, by the agreement's own definition, fundamental.

The outcome

The dispute went to the agreement's arbitration clause, and the arbitrator held for the seller on the cap question: the fundamental representations list was an exhaustive, negotiated definition, and reading in an exception for severity would rewrite the parties' own bargain rather than interpret it. The buyer recovered $375,000, the full general cap, and bore the remaining $165,000 of the reassessment itself.

What it would have cost otherwise

Had the buyer's counsel negotiated tax representations onto the fundamental list at signing — a request sellers resist precisely because it removes the cap's protection, but one increasingly common on deals where payroll or sales-tax compliance is a known risk in the target's sector — the full $540,000 reassessment would likely have been recoverable in principle, subject only to whatever separate ceiling, if any, applied to fundamental claims. The $165,000 gap traces to a negotiating point nobody raised, not to any defect in how the claim was proven.

The tell

The tell is not in the size of a potential tax exposure; it is in the fundamental representations definition itself, readable before signing. A buyer whose diligence flags payroll, sales-tax, or source-deduction risk in the target's sector should ask, at the negotiating table, whether the tax representation sits inside or outside that list — not assume severity alone will pull a claim past a cap that was never drafted to reach it.

Takeaways

• • No statute dictates which representations must be treated as fundamental, or what cap or survival treatment they receive. It is a negotiated, closed list, and it is read as one.
• • A severe loss does not become a fundamental claim by virtue of its size. Whether a representation is fundamental is decided by the agreement's own defined list, not by how much the breach ends up costing.
• • Fundamental representations are typically carved out of the general cap; general representations, including tax in most market deals, are typically subject to it. Confirm which bucket tax sits in before treating a cap as a worst-case ceiling.
• • If a target's sector carries real payroll, sales-tax or source-deduction risk, negotiate the tax representation onto the fundamental list at signing — not after a reassessment has already landed.
