A related-party exception that the sale itself cancelled

  • • Ontario, a real estate asset moved out of the operating company to a sister company by share redemption, relying on s.55(3)(a) to avoid computing a safe-income dividend.
  • • Fourteen months later the operating company’s shares sold to an arm’s length buyer for $6,800,000, as part of the same overall plan the family’s advisors had mapped out from the start.
  • • s.55(3)(a) excludes its own protection where, as part of the same series, there is a disposition of the dividend payer’s shares to an unrelated person — which is what the later sale was.
  • • The redemption dividend was recharacterised, retroactively, from a tax-free intercorporate transfer into proceeds taxed under the capital-gains-stripping rule it was structured to avoid.
  • • The fix was not complicated once found: run the actual safe-income computation before relying on the exception, or separate the two transactions by enough time and intent that they are not one series.

The situation

A family-owned distribution business, Opco, held an excess warehouse property that had appreciated well beyond its use in the business. Ahead of a planned sale of Opco’s shares, the family’s advisors wanted the real estate out of the corporation being sold — a standard isolation move, moving the asset to a related sister company, Realco, both held under the same family Holdco. The mechanism chosen was a share redemption: Opco redeemed a class of shares held by Holdco in exchange for the warehouse, a transaction that produces a deemed dividend under s.84(3).

Because Holdco and Opco were related — both controlled by the same family — and the redemption dividend qualified for the inter-corporate dividend deduction under s.112(1), the advisors reached for s.55(3)(a), the related-party exception to the capital-gains-stripping rule in s.55(2). Their reasoning: related parties don’t need a safe-income calculation, because s.55(3)(a) exists precisely to let value move between related corporations without it.

The problem

s.55(3)(a) is not unconditional. It applies “Subsection 55(2) does not apply to any dividend received by a corporation” only where, as part of the same transaction, event, or series that includes the dividend, none of five listed events involving an unrelated person occurred. One of those events is a disposition “to a person or partnership who was an unrelated person immediately before the particular time” of shares of the dividend-paying corporation. Fourteen months after the redemption, Opco’s shares were sold to an arm’s length buyer — exactly that event, and exactly the kind of disposition subparagraph (iii) is written to catch.

The advisors’ own planning memo, prepared before the redemption closed, described the warehouse transfer as “step one of the exit” and referenced the anticipated third-party sale by name. That memo, produced in diligence for the buyer’s tax counsel, made the single-series argument for the CRA before the CRA had to make it itself.

The numbers

The warehouse was transferred at its $1,400,000 fair market value; Opco’s shares sold fourteen months later for $6,800,000. Because the redemption and the sale were part of one series, the $1,400,000 dividend lost its s.112(1) shelter retroactively and was recharacterised under s.55(2) as proceeds of disposition or a capital gain rather than a tax-free intercorporate dividend — turning a transaction the family believed carried no tax cost into one that did, discovered only once the sale that triggered the disqualification had already closed.

The rule that decided it

s.55(3)(a) is an exception with its own list of disqualifying events, not a blanket carve-out for related parties. The chapeau of subsection (3) provides that s.55(2) does not apply to a dividend received on a redemption to which s.84(2) or (3) applies, “if, as part of a transaction or event or a series of transactions or events as a part of which the dividend is received, there was not at any particular time” any of five listed events. Subparagraph (iii) lists “a disposition, to a person or partnership who was an unrelated person immediately before the particular time” of shares of the corporation that paid the dividend. The exception is available for the related-party step; it is withdrawn the moment an unrelated person enters the same series anywhere along the line.

Read the unit. The question s.55(3)(a) asks is not whether the parties to this transaction were related — Holdco and Opco plainly were. It is whether the whole series, including transactions that had not yet happened when the dividend was paid, ever touches an unrelated person. A pre-sale reorganisation and the sale it is preparing for are, on ordinary CRA and judicial approaches to what a “series” is, treated as connected where one is undertaken in contemplation of the other — and a planning memo naming the anticipated buyer’s process is difficult evidence to argue around.

The structural fork is s.55(3)(b), the butterfly exception, used when the parties are not related: a pro-rata split of each type of property between the corporations, carrying its own s.55(3.1) anti-avoidance overlay. It exists for a different problem — splitting up a jointly owned corporation between unrelated co-owners — and it would not have helped here, because the disqualifying fact was the later disposition to the buyer, not the relatedness of Holdco and Opco at the time of the redemption.

The outcome

The parties filed on the basis that s.55(3)(a) applied, took the position that the redemption and the eventual sale were not one series despite the planning memo, and reserved the dividend’s tax treatment as a contested item pending review. The alternative — amending the prior year’s return to report the $1,400,000 as a capital gain and paying the resulting tax with interest from the original filing date — was quantified and disclosed to the buyer as a contingent liability, and priced into the purchase agreement as an indemnified item rather than resolved before closing.

What it would have cost otherwise

Running the actual safe-income computation before the redemption, rather than relying on relatedness alone, would have told the family in advance how much of the $1,400,000 was protected safe income and how much was not — the analysis s.55(3)(a) let them skip in the moment, and the one the later sale forced anyway. The tax outcome does not change; the surprise does.

The tell

The tell was in the advisors’ own paper trail: a transaction described internally as “step one” of a plan that named the eventual buyer is not a transaction that stands alone for series purposes, whatever the corporate relationships were on the day it closed.

Takeaways

  • • s.55(3)(a) is conditional, not a blanket related-party exemption — it withdraws the moment an unrelated person enters the same series, including a sale not yet signed when the dividend is paid.
  • • A pre-sale reorganisation undertaken in contemplation of a specific buyer process is evidence of a single series, whatever the corporate structure looked like on the day of the internal step.
  • • Where relatedness is doing all the work in the analysis, run the safe-income computation anyway — it is the fallback the moment a later, disqualifying event surfaces.
  • • s.55(3)(b), the butterfly exception, is the tool for unrelated co-owners splitting a corporation — a different provision with its own anti-avoidance overlay, not a substitute where relatedness itself is not the problem.
