Protecting New Owners From a Seller's Unpaid Sales Tax

Sunita and Farhan had four days to close on a Haliburton heating fuel business before a deadline the seller had set, and the way that deadline was handled ended up protecting them from a tax bill they never expected.

The situation

Four business days. That was the window left when Sunita and Farhan first called our office, because Halima, the owner of a home heating fuel distribution business based near Haliburton, had told her real estate agent she wanted the sale closed by the end of the following week or she would take the business off the market and keep running it herself for another year. Sunita, a paramedic, and Farhan, a respiratory therapist, had been planning the move for over a year, had financing conditionally approved, and had already given notice on their apartment in another province. A collapsed deal at this stage would have cost them more than money.

The business itself was substantial for a two-income household moving on the strength of savings and a mortgage: the purchase price sat in the high six figures, financed through a combination of the couple's own funds, a loan secured against the business assets, and a modest vendor take-back that Halima agreed to as part of the deal. It served homes and small commercial properties across a wide rural area, with fuel supply contracts, delivery trucks, and a small office staff who had worked for Halima for years and were expected to stay on.

Halima's insistence on speed was, on its face, understandable. She had a retirement plan, a place to be, and a reasonable frustration with how long the earlier stages of the sale had taken. But a fast closing on a business this size raised a specific concern that has nothing to do with either side's good faith: whether the business owed unremitted HST from before the sale, and whether that debt could follow the new owners if it was not addressed before the money changed hands.

Our office raised this early, well before the four-day window opened, but Halima's side had resisted spending time or money on it, treating it as a formality that could be sorted out after closing if it mattered at all. When the deadline arrived, that resistance became the whole story.

Sunita and Farhan had no particular reason to distrust Halima. She had run the business for close to fifteen years, the equipment and trucks were well maintained, and the staff spoke well of her. Their concern was not that she was hiding something deliberately, but that a business this size, moving fuel and collecting HST on every delivery for over a decade, was exactly the kind of operation where a bookkeeping shortfall could exist without anyone involved fully realizing it, and where the couple buying it had no independent way to confirm the account was clean before the money changed hands.

The legal question

The question at the centre of the file was whether Sunita and Farhan, buying Halima's corporation itself rather than acquiring its assets piece by piece, could end up carrying HST the corporation had failed to remit before the sale. When a buyer purchases the shares of a company, the buyer takes the company as it already exists, including whatever it owes, whether or not anyone yet knows it owes it. A corporation that falls behind on its HST remittances stays on the hook for that debt, and a change of shareholders does not wipe the slate clean. A new owner does not become personally liable for the corporation's tax debt the way a director or the corporation itself can be, but the business Sunita and Farhan were buying into, and the value of what they had just paid for, would absorb the hit if an old remittance shortfall surfaced later.

There is no shortcut that removes this risk with certainty before closing. The tax authority does not pre-clear an ordinary arm's-length purchase the way it will, in narrower circumstances, issue a certificate to an executor distributing an estate or a corporation formally winding itself up; an operating business that will keep filing its own returns afterward does not qualify for that process. The only real protections available to a buyer are contractual and practical: representations about the state of the filings, the right to review records before closing, and, if time runs short, money held back to cover what a later reassessment might reveal.

Halima's insistence on a four-day close cut off the slower of those options. There was no time for a meaningful review of years of remittance records, let alone for Halima to have her own accountant confirm her filing history was current, before the deadline she had set. That meant the real choice was not whether to verify the corporation's tax position in time, but what protection Sunita and Farhan would have if they closed without having verified it.

This is where the file turned. Rather than treat the unverified filing history as a risk the buyers would simply absorb, we told Halima's lawyer that closing on her accelerated timeline was only possible if a portion of the purchase price was held back in trust, specifically earmarked to cover any HST arrears the corporation's own records might later reveal. Halima, eager to close on her own deadline, agreed to the holdback rather than delay the sale to argue about it - a concession she made to solve her own timing problem, without fully weighing what it would mean if the arrears turned out to be real.

There was a further wrinkle worth understanding. A holdback only protects a buyer if it is tied to a real mechanism for finding out what, if anything, was owed, so part of what we negotiated was not just the dollar amount set aside but a firm commitment from Halima to keep cooperating after closing, including providing whatever records the corporation's accountant or the tax authority asked for if a review or reassessment followed, so the question would actually get resolved rather than sit unanswered in a trust account indefinitely.

What we did

  1. Flagged the HST exposure before the deadline pressure began. As soon as the price and structure were settled, we advised Sunita and Farhan that buying Halima's corporation meant buying its tax history too, and that the only real protections were a careful records review or, if time ran short, a holdback. This early warning meant the couple understood the risk long before Halima's compressed timeline forced a decision.
  2. Requested the corporation's full remittance history immediately. We asked Halima's side for the corporation's HST filing and remittance records as soon as the financial records were available, knowing a genuine review of years of filings would likely take longer than the deal's original schedule allowed. Starting early did not guarantee a complete answer in time, but it created a paper trail showing what was asked for and what was actually produced, which mattered once the deadline forced the issue.
  3. Held firm when the seller pushed to close on a bare promise. When Halima's four-day deadline arrived and the records had not been fully reviewed, her lawyer proposed closing anyway with a simple representation that the taxes were paid. We declined, explaining plainly to our clients why a promise in a document is not the same protection as money actually held back where it can be used if the promise turns out to be wrong.
  4. Negotiated a holdback in trust tied to the corporation's actual filing history. We proposed, and Halima's side accepted under time pressure, an amount held back from the purchase price in a trust account, to be released to Halima once a proper review of the remittance records confirmed no arrears, or applied against any arrears that review revealed. The amount was sized conservatively against the business's HST filing history to cover a realistic worst case.
  5. Closed on Halima's schedule with the protection in place. The deal closed within her four-day window, satisfying her need for certainty, while the holdback agreement gave Sunita and Farhan a documented, enforceable protection instead of a bare promise. Both sides got the part of the outcome that mattered most to them, even though neither got exactly the deal they had originally imagined.
  6. Managed the arrears assessment when it arrived. Roughly five months after closing, the tax authority issued an assessment for HST arrears from the period before the sale, addressed to the business. Because the holdback trust was already in place and documented, we were able to respond immediately, directing payment from the trust funds rather than scrambling to establish, after the fact, what the new owners' legal exposure actually was.
  7. Confirmed the new owners' position in writing. Once the arrears were paid from the holdback, we obtained written confirmation from the tax authority that the account was current, and we documented the full resolution for Sunita and Farhan's records, so that if any question about the business's tax history ever resurfaced, they would have a clear, closed file to point to.

The outcome

The arrears assessment, when it finally arrived, was for an amount that fell comfortably inside the holdback our office had negotiated at closing. Sunita and Farhan did not have to pay it out of the business's ongoing revenue, did not have to take on new debt to cover it, and did not have to spend months disputing liability for a debt that predated their ownership entirely.

The outcome traced back directly to Halima's own decision to force a fast close. Had she been willing to give us time to review the corporation's remittance records, there might never have been a holdback at all, and the arrears, when discovered, would have landed squarely on the business Sunita and Farhan now owned, with no fund to cover it. Her urgency ended up being the reason her buyers were protected from a risk she herself had created but never disclosed.

Halima received the balance of the holdback once the arrears were paid and the account confirmed current, minus the amount owed. She closed on the schedule she wanted and, in the end, paid what her own business owed rather than passing that cost to the people who bought it from her.

For Sunita and Farhan, the business has operated without further tax surprises since. The episode became, in the couple's own account, the clearest example from their purchase of why a protection negotiated before closing is worth more than a promise extracted from a seller with no reason to keep it after the money has changed hands.

The episode also left the couple with a clearer sense of what to watch for going forward. Fuel distribution collects HST on nearly every transaction, so even a modest remittance gap can add up over time. Sunita and Farhan now review their own filings with an accountant on a tighter schedule than the previous owner had kept, not because they expect a similar surprise from their own conduct, but because receiving someone else's tax bill made the cost of inattention concrete in a way it had not been before.

What you can learn from this

  • Buying the shares of a company means buying its tax history too; no certificate clears an ordinary purchase the way one exists for an estate, so a holdback is often the only real protection against a seller's old remittances.
  • A seller's urgency to close quickly is not a reason to skip protections; it can be a reason to insist on a holdback instead of a bare promise.
  • A representation in a purchase agreement is only as good as your ability to collect on it later; money already held back in trust does not depend on anyone's continued cooperation.
  • Size a holdback against the seller's actual filing history where possible, so it is neither symbolic nor so large it becomes its own point of negotiation.
  • When a deadline is being driven by the other side's timeline rather than yours, that pressure can sometimes be used to secure a protection they would otherwise resist.
