Anonymised, illustrative composite. A shareholder-loan write-down documented as a one-line side letter looked like balance-sheet cleanup. It was a forgiven amount under the Income Tax Act, and it ran straight through the target’s own tax attributes before the ink was dry.
At a glance
A mid-market manufacturer was being sold for $2,850,000. Over several years, the departing controlling shareholder had left unpaid compensation and advances in the corporation, building up to a $650,000 shareholder loan owed by the TARGET to him personally — not a note between buyer and seller, but a debt the corporation itself owed one of its own shareholders.
The buyer did not want that $650,000 debt sitting on the target’s balance sheet after closing, and negotiated for the departing shareholder to forgive most of it as part of the overall deal — economically, in place of a higher purchase price. The parties agreed the target would pay $150,000 at closing from available cash, and the shareholder would forgive the remaining $500,000. Both sides’ corporate lawyers documented it as a one-line side letter — “Seller agrees to forgive $500,000 of the outstanding shareholder loan effective at Closing” — and treated it as a financing detail. Neither side’s tax advisor saw the letter until late in negotiations.
The target carried $310,000 of non-capital losses from a rough two-year stretch before the sale process began, and the buyer’s own deal model had assumed those losses would shelter roughly $80,600 of future tax over the following three years — value the buyer believed it was acquiring along with the business.
$500,000 forgiven. $310,000 of non-capital losses, previously valued by the buyer at $80,600 of future shelter, eliminated entirely. $190,000 remaining, grinding the target’s equipment undepreciated capital cost from $340,000 to $150,000. The final $50,000, grinding the adjusted cost base of a target-owned investment property from $920,000 to $870,000 — a smaller cost base that will produce a larger taxable capital gain whenever the target eventually sells it.
The forgiven $500,000 is a “forgiven amount” on a “commercial obligation” under ITA s.80(1) — the loan was interest-bearing and issued by the target as debtor — and s.80(3) does not let the parties direct where it lands: “Where a commercial obligation issued by a debtor is settled at any time, the forgiven amount at that time in respect of the obligation shall be applied to reduce at that time, in the following order, (a) the debtor’s non-capital loss for each taxation year that ended before that time.” The debtor here is the TARGET, because the forgiven debt was the target’s own obligation, not a note owed by the buyer.
Read the unit. The $310,000 loss pool absorbed the first $310,000 of the forgiveness automatically, in full, the moment the debt was settled — it did not matter that the side letter never mentioned the loss pool, and it did not matter that neither side’s corporate counsel connected the two documents. Once non-capital losses are exhausted, the statutory order moves on: capital cost allowance and undepreciated capital cost under later subsections, then the adjusted cost bases of other capital property, in sequence, until the forgiven amount is used up.
The buyer’s tax advisor traced the mechanic before closing, once finally shown the side letter, and the deal was repriced: the purchase price was reduced by $46,000, reflecting the $80,600 of lost tax-shield value the buyer had modelled, net of the value of not having to fund the remaining $500,000 of the original $650,000 loan itself. The share purchase agreement also added a representation that no further forgiveness of shareholder debt would occur without the buyer’s consent, and a tax indemnity specifically carved out for any reassessment relating to the attribute grind.
Had the reprice not happened, the buyer would have paid full price for a $310,000 loss pool that ceased to exist the moment the “favour” to the departing shareholder closed, and its post-closing capital cost allowance claims would have been smaller than the original model assumed — understating real after-tax cash flow in exactly the years the buyer was counting on the loss pool to help fund the transition.
The side letter was a corporate-and-financing document, reviewed by corporate counsel on both sides and never routed to either party’s tax advisor until late — a silo failure between the lawyers structuring the deal and the accountants modelling its after-tax economics. A one-line forgiveness clause looks like nothing on the page it is written on; its consequence lives entirely in a different statute neither drafter was reading for.
