A non-resident vendor’s clearance certificate and the purchaser’s withholding

Anonymised, illustrative composite. One of four founding shareholders had moved to Florida years earlier. The buyer's own diligence found it. Section 116 made that discovery the buyer's problem, not just hers.

At a glance

  • • Four founding shareholders sold 100% of a private manufacturing company for $9,600,000. One shareholder, holding 22% of the shares, had been non-resident for Canadian tax purposes since relocating to Florida years earlier.
  • • The company owned its 140,000-square-foot manufacturing plant outright, and more than 50% of the fair market value of the shares came from that Canadian real property — meeting the statutory test that makes private-company shares “taxable Canadian property.”
  • • ITA s.116(5) makes a purchaser personally liable for 25% of the non-resident vendor's proceeds, remitted to the Receiver General, unless a clearance certificate under s.116(4) is obtained or the purchaser can show no reason to have believed the vendor was non-resident.
  • • Because the buyer's own diligence had surfaced her Florida address, the reasonable-inquiry defence was never available — the exposure had to be managed through the certificate procedure, not avoided by looking away from what diligence had already found.

The situation

Four founding shareholders agreed to sell 100% of the shares of a private manufacturing company for $9,600,000. Three of the four had lived and worked in Ontario throughout the company’s history. The fourth, holding 22% of the shares — roughly $2,112,000 of the total consideration — had relocated to Florida six years earlier and had been non-resident for Canadian tax purposes ever since, a fact that surfaced in ordinary diligence when the buyer’s counsel reviewed the shareholders’ addresses and banking instructions for closing.

The company owned its manufacturing facility outright — a 140,000-square-foot plant on land it had held for over two decades, representing more than half of the business’s total fair market value on any reasonable allocation between real property and everything else the business owned.

The problem

That real-property concentration mattered because it determined whether the shares were the kind of property a non-resident vendor’s tax status turns into the buyer’s problem. Private-company shares are “taxable Canadian property” under ITA s.248(1) where, at any time in the 60 months before the disposition, “more than 50% of the fair market value of the share…was derived directly or indirectly…from one or any combination of (i) real or immovable property situated in Canada, (ii) Canadian resource properties, (iii) timber resource properties…”. An identical manufacturing business that leased its plant instead of owning it would very likely fall outside that test entirely; this one, because it owned the real estate its value concentrated in, was squarely inside it.

Once the shares are taxable Canadian property and the vendor is non-resident, the exposure runs to the buyer, not the seller.

The numbers

The non-resident shareholder’s 22% stake represented $2,112,000 of the $9,600,000 purchase price. With no clearance certificate in place at closing and no certificate limit fixed against which to net the calculation, the buyer’s exposure under s.116(5) was 25% of the full amount paid for her shares — $528,000 — a sum the buyer would be personally liable to remit to the Receiver General within 30 days after the month of acquisition, out of its own funds, regardless of what it had actually paid her.

The rule that decided it

The regime runs on the vendor first and the purchaser second. ITA s.116(1) lets a non-resident vendor notify the Minister of a proposed disposition of taxable Canadian property before it happens; under s.116(2), once the vendor pays 25% of the estimated gain to the Receiver General or furnishes acceptable security, “the Minister shall forthwith issue to the non-resident person and the proposed purchaser a certificate in prescribed form…fixing therein an amount…referred to as the ‘certificate limit.’” s.116(4) does the same thing after the fact, for a disposition that has already occurred.

The purchaser’s liability sits in s.116(5): “Where in a taxation year a purchaser has acquired from a non-resident person any taxable Canadian property…the purchaser, unless (a) after reasonable inquiry the purchaser had no reason to believe that the non-resident person was not resident in Canada…or (b) a certificate under subsection 116(4) has been issued to the purchaser…is liable to pay, and shall remit to the Receiver General within 30 days after the end of the month in which the purchaser acquired the property…25% of the amount, if any, by which (c) the cost to the purchaser of the property so acquired exceeds (d) the certificate limit fixed by the certificate, if any…and is entitled to deduct or withhold from any amount paid or credited by the purchaser to the non-resident person…any amount paid by the purchaser as such a tax.” Two, and only two, things reduce that exposure: a certificate fixing a limit below the full cost, or the reasonable-inquiry defence in paragraph (a). Here, the buyer’s own diligence had already put it on notice of the vendor’s Florida residency — which forecloses paragraph (a) as a matter of fact, since the buyer plainly did have reason to believe she was non-resident. The certificate route was the only one left.

The outcome

Counsel structured closing so the non-resident shareholder filed her s.116(1) notice of proposed disposition well ahead of the scheduled closing date, and paid the requisite 25% of her estimated gain to the Receiver General to obtain a certificate fixing a certificate limit. Because the certificate could not be guaranteed to issue before the closing date the other three shareholders needed, the purchase agreement also built in a contractual mechanism specific to her: 25% of her portion of the price — the same $528,000 the statute would otherwise expose the buyer to — was withheld from her proceeds at closing and held in escrow, released to her once the certificate confirmed the buyer’s statutory liability had been satisfied or eliminated. The other three shareholders, all Canadian residents throughout, closed without any withholding at all.

What it would have cost otherwise

Closing without a certificate and without the reasonable-inquiry defence available would have left the buyer personally liable for $528,000 payable to the Receiver General within 30 days of the month of acquisition — a liability entirely independent of what the buyer had actually paid the vendor, and one the buyer could only partially recover by withholding from her proceeds after the fact, a much weaker position than fixing the exposure before funds moved.

The tell

The tell was that the buyer’s own diligence created the problem it then had to solve. A purchaser who genuinely has no reason to suspect non-residency keeps the reasonable-inquiry defence and faces essentially no exposure, whatever a vendor’s actual status turns out to be. The moment ordinary closing diligence — an address on a banking form, a W-8-style tax form, correspondence routed to a US address — puts the buyer on notice, that defence is gone, and it cannot be un-known. Diligence that finds the fact and then proceeds to closing without addressing it is worse than diligence that never looked.

Takeaways

  • • Private-company shares are taxable Canadian property only if more than 50% of their fair market value derives from Canadian real property, resource property or timber property over the preceding 60 months — an operating company that owns its premises can be caught where an identical company that leases them is not.
  • • ITA s.116(5) puts a 25%-of-cost withholding liability on the purchaser of taxable Canadian property from a non-resident vendor, not on the vendor — and it is a statutory liability, not a negotiated one.
  • • The reasonable-inquiry defence in s.116(5)(a) disappears the moment the purchaser's own diligence gives it actual reason to suspect non-residency — after that, only the certificate procedure is left.
  • • Where a certificate cannot be confirmed before a scheduled closing, a contractual holdback sized to the statutory 25% protects the purchaser's own cash position without changing what the statute itself requires.
