Anonymised, illustrative composite. A seller structured $600,000 of a $3,000,000 sale price as a vendor take-back note. Fourteen months later the buyer refinanced and repaid it in full — and the capital gains reserve the seller had claimed reversed into the following year’s income.
At a glance
A vendor selling a services business to an independent sponsor agreed to a $3,000,000 price, with $2,400,000 paid in cash at closing and the remaining $600,000 structured as a vendor take-back note — a deferred payment secured against the business, inside the range deavo.ai’s financing commentary describes as typical for a VTB of 10 to 20 percent of price over a three-to-five-year term. Deavo’s own vendor-take-back guidance is explicit that these structures “vary widely and involve real financial and legal risk for sellers” and commonly carry security registered under the applicable province’s personal property security legislation, which this note did.
The seller’s adjusted cost base in the shares was $900,000, producing a $2,100,000 capital gain on the sale. Under the general rule, that whole gain is taxable in the year of disposition — but the take-back structure meant $600,000 of the proceeds were not actually due to the seller until later years, and paying tax on money not yet received would have created a real cash-flow problem for a seller who had just given up the business as their income source.
The capital gains reserve under ITA section 40(1)(a)(iii) let the seller defer the portion of the gain matching the proceeds not yet due. The claimable amount is the lesser of two limbs: clause (C), “a reasonable amount as a reserve in respect of such of the proceeds of disposition of the property that are payable to the taxpayer after the end of the year”; and clause (D), “1/5 of the amount determined under subparagraph 40(1)(a)(i)…multiplied by the amount, if any, by which 4 exceeds the number of preceding taxation years of the taxpayer ending after the disposition.” Clause (D) is what forces at least a fifth of the gain into income each year and empties the reserve by year five; clause (C) is what ties it to money genuinely still owing. With $600,000 of the $3,000,000 price (20%) deferred at the Year 1 year-end, the seller claimed a $420,000 reserve (20% of the $2,100,000 gain), reporting $1,680,000 of gain in Year 1 and carrying $420,000 forward.
Two subparagraphs do the work, and the file turns on the one that is easy to miss. Clause (C) of section 40(1)(a)(iii) ties the reserve to what remains payable at each year-end — it is not a fixed multi-year amortization schedule the seller locks in once. Separately, section 40(1)(a)(ii) provides that where property “was disposed of before the year,” the taxpayer’s gain for the current year includes “the amount, if any, claimed by the taxpayer under subparagraph 40(1)(a)(iii) in computing the taxpayer’s gain for the immediately preceding year.” Every reserve is therefore added straight back the following year and can only be deferred again by claiming a fresh reserve. When the buyer refinanced its senior debt fourteen months after closing and retired the vendor take-back note in full, the $600,000 that had been “not yet due” became fully received partway through Year 2. The Year 1 reserve came back in under 40(1)(a)(ii) as it always would have; what changed is that with nothing outstanding at the Year 2 year-end there was no clause (C) room to re-claim it. The entire $420,000 landed in Year 2 rather than trickling out over the note’s original three-to-five-year schedule.
The seller’s Year 2 return reported the full $420,000 remaining gain, on top of whatever gain the Year 2 investment income otherwise generated, and the seller’s accountant had flagged the acceleration risk when the refinancing was first discussed — not a surprise at filing time, but a planned-for one. The seller’s total gain across both years reconciled exactly to the original $2,100,000: $1,680,000 in Year 1, $420,000 in Year 2. For the mechanics of the note itself, see how a vendor take-back note is structured, and for the buyer-side financing constraint that often drives sellers toward a VTB in the first place, see why a management buyout leaned on seller financing to close the gap.
Had the note run its planned course instead of being repaid early, the $420,000 reserve would have unwound gradually against the note’s own amortization — smaller taxable amounts spread across the remaining term rather than one full year’s acceleration. The seller did not lose any of the $2,100,000 gain either way; what changed is when it was taxed. Being told in advance, before the refinancing closed, that early repayment would collapse the reserve into a single year is what let the seller plan Year 2 cash flow around a tax bill that landed a year earlier than the original note schedule implied.
A seller who structures a VTB purely around the note’s stated term, without asking what happens to the deferred gain if the buyer refinances or otherwise repays early, is planning around a schedule the buyer does not actually control. The refinancing decision sits entirely with the buyer’s capital structure, not the seller’s tax plan — any seller carrying paper should ask, before signing, what an early payoff does to the reserve, not after the wire arrives. Whether the buyer may prepay at all, and at what cost, is purely a matter of what the note says — nothing in Ontario law requires a vendor take-back note either to permit or to prohibit penalty-free prepayment. A prepayment clause that gives the seller advance notice of a refinancing, even without a penalty attached, at least converts the tax-timing surprise into a tax-timing heads-up.
