Anonymised, illustrative composite. A vendor take-back note renegotiated after a buyer’s rough year looks like a straightforward kindness. The Income Tax Act treats the same forgiveness two different ways on two different returns, and the buyer’s side is not free.
At a glance
A retiring machine-shop owner sold the business for a price that included a $900,000 vendor take-back note, six-year term, secured by a pledge of the buyer’s shares and a general security agreement over the business assets. Two years in, the buyer lost a major account and could keep up with interest but fell behind on scheduled principal, with $740,000 still outstanding.
Rather than enforce the security or sue — expensive, slow, and likely to recover less than the business was actually worth — the seller, a retiree with no interest in running a lawsuit, agreed to renegotiate. The parties settled on forgiving $310,000 of the outstanding $740,000, cutting the note to $430,000, in exchange for a shortened two-year remaining term at a higher rate and a modest 4% non-voting equity stake for the seller as an upside kicker. Both sides’ lawyers documented it as a straightforward amendment to the note. Neither side’s tax advisor was consulted before it was signed.
$310,000 forgiven, note reduced from $740,000 to $430,000. Separately, the buyer had accumulated $190,000 of its own non-capital losses over the difficult two years since closing — a pool it was counting on to shelter income once the business recovered.
The same $310,000 event produces two different, asymmetric tax consequences, one on each side of the note. On the seller’s side, s.50(1) lets a creditor holding a debt “established by the taxpayer to have become a bad debt in the year” elect to be “deemed to have disposed of the debt…at the end of the year for proceeds equal to nil and to have reacquired it immediately after the end of the year at a cost equal to nil,” crystallizing a loss on the forgiven portion — but only if the debt is genuinely established as bad, not merely reduced by mutual agreement as a commercial accommodation.
On the buyer’s side, the VTB note is a “commercial debt obligation” under s.80(1): “a debt obligation issued by the debtor (a) where interest was paid or payable by the debtor in respect of it pursuant to a legal obligation.” The $310,000 reduction is a “forgiven amount…in respect of a commercial obligation issued by a debtor…the amount determined by the formula A - B where A is the lesser of the amount for which the obligation was issued and the principal amount of the obligation.” And s.80(3) does not let the buyer choose where that forgiven amount 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.”
Read the unit. The order is mandatory and starts with the debtor’s own non-capital losses, dollar for dollar, before touching undepreciated capital cost or the adjusted cost base of any other property. The buyer’s $190,000 non-capital loss pool was directly in the path of the $310,000 forgiven amount — and eliminated first, regardless of how the parties themselves characterized the renegotiation.
Once the buyer’s accountant traced the mechanic, the numbers were unavoidable: the entire $190,000 non-capital loss pool was extinguished against the forgiven amount, and the remaining $120,000 began grinding down the undepreciated capital cost of the buyer’s equipment, reducing future capital cost allowance claims. The parties could not undo the forgiveness — it had already closed — so the buyer instead adjusted its own go-forward tax planning around the smaller loss shelter and reduced CCA pool, and both sides agreed, for any future renegotiation, that tax counsel would review a proposed VTB forgiveness before it was signed rather than after.
Nothing about the note amendment itself would have flagged this — the reduction reads on its face as a straightforward accommodation between two private parties, with no filing, election or third-party notice required to take effect. A buyer that did not check would have discovered the loss pool was gone only when it tried to use it against future income and found nothing left to shelter it with.
The renegotiation was framed, by both sides, as help for a buyer going through a rough patch — a characterization that is accurate commercially and irrelevant to s.80, which does not care why a commercial obligation was settled, only that it was. A concession meant as a kindness cost the buyer more in lost tax attributes than the $310,000 write-down itself was worth in cash relief.
