The QSBC test that had to look through the holding company to the operating company

Anonymised, illustrative composite. A holding company with exactly one asset, and a test that does not stop at that asset.

At a glance

  • • Ontario, sale of 100% of a holding company’s shares for $4,100,000; the holding company’s only asset was 100% of the shares of an active manufacturer.
  • • To be a qualified small business corporation share, s.110.6(1) requires the share to be, at the determination time, a share of a “small business corporation” — and a holding company whose only asset is shares of another corporation is tested by looking through to that corporation.
  • • s.248(1) defines a small business corporation as one whose assets are “all or substantially all” active-business assets, or shares or debt of a connected corporation that is itself a small business corporation on the same test.
  • • The operating company had swept eight years of retained earnings into a managed securities account. On closing day the account exceeded the fair market value of the active manufacturing assets underneath it.
  • • Because the operating company was not a small business corporation, the holding company’s shares failed the exemption test — even though the holding company itself held nothing but shares of an operating manufacturer.

The situation

Marcus incorporated MDH Holdings Inc. in 2011 to hold his shares in Pallisade Fabrication Ltd., a CNC machining shop he had built from a two-man shop into a 26-employee operation. MDH Holdings held nothing else: no real estate, no operating assets of its own, just 100% of Pallisade’s common shares. When an arm’s length buyer offered $4,100,000 for MDH Holdings’ shares, Marcus’s accountant began modelling the sale on the assumption that the shares would qualify for the lifetime capital gains exemption — MDH Holdings had held Pallisade for thirteen years, well past any ownership-period concern.

The assumption skipped a step. A qualified small business corporation share is defined in s.110.6(1), and paragraph (a) of that definition requires the share to be, at the determination time, “a share of the capital stock of a small business corporation”. MDH Holdings’ shares are shares of MDH Holdings — so the question is not whether Pallisade is a small business corporation, it is whether MDH Holdings is one. And MDH Holdings owns nothing but Pallisade shares.

The problem

s.248(1) defines “small business corporation” for the whole Act, and the definition is built to look through a holding company rather than stop at it. It describes a corporation “a Canadian-controlled private corporation all or substantially all of the fair market value of the assets of which at that time is attributable to assets that are” active-business assets, or, under paragraph (b), “shares of the capital stock or indebtedness of one or more small business corporations that are at that time connected with the particular corporation”. The word doing the work is the second “small business corporations” — the connected corporation has to independently meet the same test, not merely exist.

Diligence pulled Pallisade’s own balance sheet, not just MDH Holdings’. Pallisade had been profitable for years and its bookkeeper, on the accountant’s standing instruction, swept surplus cash quarterly into a managed account of bonds, preferred shares and index funds rather than leaving it idle in an operating chequing account. Nobody had ever mapped that account against the active-business assets it now dwarfed.

The numbers

At the valuation date, Pallisade’s active manufacturing assets — equipment, receivables, inventory, work-in-progress and goodwill attributable to the shop floor — totalled $2,650,000. The managed securities account held $3,050,000. On a combined fair market value of $5,700,000, only 46.5% of Pallisade’s own assets were active-business assets: short of even a bare majority, let alone “all or substantially all.”

Because Pallisade itself failed the test, MDH Holdings had no qualifying asset to point to. Its entire $5,700,000 of value ran through a corporation that was not, on its own facts, a small business corporation — so none of it counted toward MDH Holdings meeting the same test one tier up.

The rule that decided it

s.110.6(1) builds the same look-through directly into the QSBC-share definition itself, for the 24 months before the determination time. Paragraph (c) requires the share to have been, throughout that period, a share of a Canadian-controlled private corporation “more than 50% of the fair market value of the assets of which was attributable to” either assets used in an active business, or, under subparagraph (c)(ii), “shares of the capital stock or indebtedness of one or more other corporations that were connected” with it — provided those shares or debt were themselves, per clause (B), “more than 50% of the fair market value of the assets of which was attributable to assets described in subparagraph (iii)”. Read the unit: it is not enough for Holdco to hold shares of a connected corporation. That connected corporation’s own asset mix has to clear the same bar, tested on its own facts.

s.248(1) carries the identical structure for the point-in-time “small business corporation” definition that feeds paragraph (a) of the s.110.6(1) test: “a Canadian-controlled private corporation all or substantially all of the fair market value of the assets of which at that time is attributable to assets that are” active-business assets or, in paragraph (b), “shares of the capital stock or indebtedness of one or more small business corporations that are at that time connected with the particular corporation”. Both definitions are recursive by design — a holding company is never tested in isolation from what it holds.

Two shareholders each holding their own holding company changes the answer, not the rule. Each holding company is tested separately, on its own assets and its own connected corporation — so where two founders each rolled their Pallisade shares into a personal holdco, one holdco could clear the test on identical Opco facts if its shareholder’s personal holdco held nothing else, while the other failed because that shareholder’s holdco also carried an unrelated passive rental property. The look-through runs corporation by corporation, not family by family.

The outcome

The sale did not collapse, but the tax plan did. Marcus’s advisors purified Pallisade before closing — paying out $2,200,000 of the securities account as an eligible dividend and holding back working capital — which brought Pallisade’s active-asset ratio to roughly 84% of a smaller $3,500,000 total, clearing the “all or substantially all” bar with room the file’s counsel was comfortable defending. That took eleven weeks and pushed the closing date twice.

The purification dividend was itself a taxable event to MDH Holdings, offset in part by the capital dividend account where available, and Marcus’s exemption claim on the eventual $4,100,000 sale went ahead once the look-through test was actually satisfied — not assumed.

What it would have cost otherwise

Had the sale closed on the original schedule with the securities account left in place, the exemption claim would have been vulnerable to reassessment on audit at any point within the normal reassessment period, with the assessed gain becoming fully taxable and Marcus’s advisors exposed for having signed off on a claim the corporation’s own balance sheet did not support. Purifying before signing, rather than after, is the difference between a due-diligence finding and a reassessment.

The tell

The tell was structural, not behavioural: nobody had ever asked what Pallisade’s own asset mix was, because everyone’s attention was on MDH Holdings, the entity whose shares were actually being sold. A holding company with a single asset reads as simple. It is exactly the structure the look-through test is built for.

Takeaways

  • • s.110.6(1)(c)(ii) and s.248(1)(b) both look through a holding company to the corporation whose shares it holds — a holdco is never tested on its own balance sheet alone.
  • • Test the connected corporation’s asset mix independently, on its own facts, before assuming a one-asset holdco automatically inherits a clean bill from an active operating subsidiary.
  • • Two shareholders with separate personal holdcos can land on different sides of the same test on identical Opco facts — the look-through runs corporation by corporation.
  • • Purify before the purchase agreement is signed, not after the exemption claim is challenged — the tax cost of the dividend is the same either way; the audit exposure is not.
