Case File · Transferee Tax Liability

The building moved to the founder’s holdco for $1, and it did not make the operating company’s tax debt any safer to buy

Anonymised, illustrative composite. A pre-sale asset-protection move the founder made for reasons that had nothing to do with the deal, and a provision that means it protected nobody — it just added a second name CRA could collect from.

  • • Ontario, proposed share purchase of an operating company. Eighteen months before the sale process began, the founder transferred the company’s owned commercial building, fair market value $2.1 million, to his personal holding company for $1.
  • • Diligence separately identified a contingent CRA reassessment risk in the transfer year, ultimately quantified at $340,000 of potential tax owing by the operating company for that year.
  • • ITA s.160(1): a transferee who received property from a related person for less than fair market value is “jointly and severally … liable” for the transferor’s tax, up to the lesser of the value gap and the transferor’s outstanding tax.
  • • That liability runs alongside the operating company’s own tax debt, not in place of it — the transfer did not reduce what the buyer’s target owed by a single dollar.
  • • s.160(2) lets the Minister assess “at any time” — there is no limitation period cutting off the transferee liability, so the exposure does not age out the way an ordinary reassessment risk does.

The situation

A buyer was negotiating a share purchase of an Ontario operating company. Eighteen months before the sale process began, the founder had transferred the company’s owned commercial building — fair market value $2.1 million — to his personal holding company for $1, as part of an asset-protection and estate plan that had nothing to do with the eventual sale. At the time, the operating company continued to lease the building back from the holdco at market rent, and the transfer was disclosed in diligence as an ordinary related-party reorganisation.

Separately, tax diligence identified that the operating company had claimed a research-and-development credit for the same taxation year in which the building was transferred, and that the claim carried real risk of a CRA reassessment. Counsel quantified the exposure, if reassessed, at approximately $340,000 in additional tax for that year.

The problem

The founder’s advisor initially treated the two facts as unrelated — a legitimate asset-protection transfer on one hand, an ordinary tax-audit risk on the other, priced separately in the deal. The buyer’s tax counsel read them together and reached a different conclusion: because the building left the operating company for nominal consideration in the same year the company carried an unresolved tax exposure, the transfer had created a second, additional debtor for the same liability — and had not relieved the operating company, the buyer’s actual target, of any part of it.

The numbers

Value transferred for less than fair market value: $2,099,999 ($2.1 million less the $1 paid). Contingent tax debt in the transfer year: $340,000. Under s.160(1), a transferee’s liability is capped at the lesser of the value gap and the transferor’s outstanding tax — here, the full $340,000, since the value gap comfortably exceeded it. That figure did not change the operating company’s own exposure at all: if CRA reassessed, it could pursue the operating company for the full $340,000, the holdco for the same $340,000, or both, up to full satisfaction of the single debt. The buyer’s target was on the hook for exactly what it would have owed had the building never moved.

The rule that decided it

ITA s.160(1) applies where a person transfers property, directly or indirectly, to “a person with whom the person was not dealing at arm’s length” — a wholly owned personal holding company qualifies without argument. Where that applies, “the transferee and transferor are jointly and severally … liable to pay under this Act an amount equal to the lesser of (i) the amount, if any, by which the fair market value of the property at the time it was transferred exceeds the fair market value at that time of the consideration given for the property, and (ii) the total of all amounts … that the transferor is liable to pay under this Act … in or in respect of the taxation year in which the property was transferred or any preceding taxation year.”

The word doing the work is “jointly.” s.160(1) does not transfer the operating company’s liability to the holdco in the sense of relieving the company of it — it makes the holdco liable in addition. Both remain fully on the hook for the same underlying debt until it is paid, from either of them or both together. A founder who believes moving an asset out protects the operating company from its own tax exposure has the mechanic backwards: it does not shrink the company’s liability by a dollar, and it hands CRA a second, more easily collectible target in the holdco — a solvent entity holding a $2.1 million building, likely a more attractive collection target than an operating company whose sale proceeds may already be spent.

s.160(2) removes any comfort from the passage of time: “The Minister may at any time assess a taxpayer in respect of any amount payable because of this section…” There is no ordinary reassessment-period cutoff on the transferee liability itself — it survives as long as the underlying tax debt does, independent of how long ago the transfer took place. The eighteen months between the transfer and the sale process did nothing to age the exposure out.

The parallel provision on the GST/HST side, ETA s.325(1), reaches the identical fact pattern for any unremitted net tax the operating company owed for the period: the transferee and transferor are “jointly and severally … liable” under a near-identical formula, with its own definitions and its own assessment machinery run separately from the income-tax side. A target with a clean income-tax position but an outstanding GST/HST liability can still expose a related-party transferee through this limb alone.

The outcome

The deal proceeded, but the purchase agreement was rewritten around what diligence had actually found. The tax indemnity was extended specifically to cover any amount the operating company was assessed for the transfer year, with no cap tied to the ordinary escrow release schedule, since s.160(2)’s open-ended assessment window meant the ordinary escrow term did not match the real tail risk. The founder personally — as the controlling mind of the holdco — gave a separate indemnity running directly to the buyer for any amount CRA collected from the operating company in respect of the R&D credit reassessment, closing the gap between where the risk legally sat and where the parties agreed it should land commercially.

What it would have cost otherwise

Had the buyer accepted the seller’s framing that the building transfer was an unrelated, already-completed piece of estate planning, the standard indemnity and escrow terms in the template purchase agreement would have run on the ordinary reassessment timeline — typically three to four years — while the actual transferee-liability exposure under s.160(2) has no such limit. A reassessment landing in year five or six would have left the operating company, by then wholly owned by the buyer, on the hook for the full $340,000 with no recourse against a seller whose indemnity obligations had already expired.

The tell

The tell was the timing coincidence itself: a related-party transfer for nominal consideration, in the same taxation year as an unresolved tax position. Any pre-sale transfer to a spouse, a family holding company, or a sister entity deserves the same question diligence asked here — not whether the transfer was legitimate on its own terms, which it usually is, but whether the transferor carried any tax exposure at the time it happened. A pre-sale reorganisation is a diligence item in its own right, not a tax-planning footnote to be taken at face value because it predates the sale process.

Takeaways

  • • ITA s.160(1) makes a related-party transferee jointly and severally liable for the transferor’s tax, up to the lesser of the value gap and the transferor’s outstanding liability — it adds a debtor, it does not replace one.
  • • The transferor’s own liability is completely unaffected. A buyer acquiring the transferor gains no protection from an earlier related-party transfer, however large.
  • • s.160(2) allows assessment “at any time” — there is no ordinary limitation period cutting off transferee liability, so a standard escrow or indemnity term calibrated to normal reassessment timelines will not cover the full tail.
  • • ETA s.325(1) runs the identical analysis for GST/HST, independently of the income-tax position.
  • • Check every related-party transfer in the two to three years before a sale against the transferor’s tax position at the time it happened — not against whether the transfer itself looks legitimate.
