Structuring a Business Sale to Protect a $1.25 Million Exemption

The situation

Liang had built a construction company in Huntsville over nearly two decades, growing it to roughly 30 employees and a solid book of regional commercial and residential contracts. In late 2025, a regional developer named Dimitri approached with an offer to buy the business outright, and by the time Liang signed a letter of intent, the numbers on the table were real: roughly $3.6 million, with a target closing about ten months out.

Liang came to Treadstone Law with the letter of intent in hand, along with spouse Yan, a specialist physician who ran a separate professional corporation for her medical practice. Neither the letter of intent nor the accountant's early notes had addressed how the sale would actually be structured — and structure, in a deal this size, is often worth more than the negotiated price itself.

The letter of intent described the transaction only in general terms: a purchase of "the business and its assets." That phrase, more than anything else in the file, was the first thing our team flagged.

What the projections showed

An asset sale — where the buyer purchases the company's individual assets (equipment, contracts, goodwill) rather than its shares — is usually the buyer's preferred structure. It lets the buyer choose which liabilities to assume and gives them a stepped-up tax basis in the assets going forward. For Dimitri, an asset purchase made sense. For Liang, it created a serious problem.

When a corporation sells its assets, the resulting gain is taxed inside the corporation first, at corporate tax rates. To get the proceeds into Liang's hands personally, the corporation then has to pay them out, typically as a dividend, which is taxed again at the personal level. Ontario's dividend tax credit softens that second layer, but it does not eliminate it. Modelled against the alternative — a share sale, where Liang sells the shares of the corporation directly to Dimitri and the gain is taxed once, personally, as a capital gain — the two structures produced meaningfully different after-tax outcomes on the same $3.6 million price.

Layered on top of that was a second issue specific to share sales: the lifetime capital gains exemption for qualified small business corporation shares under the Income Tax Act. This exemption shelters up to roughly $1.25 million of capital gain per individual from tax entirely — not a rate reduction, but a true exclusion. To qualify, though, the shares have to meet an active-asset test: substantially all of the corporation's assets need to be used in an active business, both at the moment of sale and throughout the two years before it. Liang's company had accumulated a meaningful cash reserve over the years, plus a small rental property held inside the corporation as a passive investment. Neither was disqualifying on its own, but together they pushed the company below the active-asset threshold the exemption requires.

Our team ran the numbers across both variables — deal structure and exemption eligibility — and the spread between the best and worst realistic outcomes came out to roughly $400,000 to $900,000 in additional tax, depending on how much of the passive-asset problem got fixed before closing and whether the deal proceeded as an asset sale or a clean share sale. That was the number that mattered: not the sale price on the letter of intent, but the tax exposure sitting underneath it.

What we did

1. Modelled both structures side by side. Before any negotiation with Dimitri's side, we built out the after-tax comparison between an asset sale and a share sale on the actual numbers in Liang's file — corporate tax on the gain, personal tax on distributed proceeds, and the effect of the exemption if it survived. The share sale was clearly better for Liang; the question was whether it was achievable given Dimitri's stated preference.
2. Began purifying the corporation. To meet the active-asset test, the company needed to shed its passive holdings well before closing — not at the last minute, since the test looks at the two years leading up to the sale, not just the closing date itself. We coordinated with Liang's accountant to move the excess cash and the rental property out of the operating company and into a newly formed holding company, using a tax-deferred rollover so the transfer itself didn't trigger tax. This work started immediately, giving the company the better part of a year to sit clean before closing.
3. Negotiated the structure with the buyer's side. We went back to Dimitri's lawyers with the after-tax analysis and proposed a share purchase instead of an asset purchase, addressing the buyer's usual objections directly: a set of detailed representations and warranties about the company's liabilities, a holdback of part of the purchase price for a period after closing to cover any undisclosed exposure, and specific indemnities tied to pre-closing tax matters. These terms gave Dimitri comparable protection to what an asset deal would have provided, without the double-taxation cost to Liang.
4. Reviewed Yan's professional corporation alongside Liang's file. Because the two corporations were unrelated but the household's overall tax position moved together, we looked at the timing of dividends out of Yan's medical practice corporation for the same tax year the sale would close, to avoid stacking a large capital gain and a large dividend into a single year and pushing both into needlessly high marginal brackets.
5. Coordinated the capital dividend account planning. Once the exemption sheltered the first roughly $1.25 million of gain, the remainder of the taxable capital gain still generated a credit to the corporation's capital dividend account — a mechanism that lets a portion of future corporate distributions flow out to shareholders tax-free. We worked with the accountant to make sure that credit was tracked and available in case any residual proceeds needed to move through the corporation after closing.
6. Drafted and negotiated the purchase agreement. With the structure settled, our team drafted the share purchase agreement, negotiated the holdback and indemnity terms to a level acceptable to both sides, and managed the closing mechanics through to the actual transfer of shares.

The outcome

The purification work was completed roughly six months into the ten-month window, with time to spare before the active-asset test's two-year look-back period would matter at closing. The deal closed as a share sale at the originally negotiated price of about $3.6 million. Liang's lifetime capital gains exemption applied in full, sheltering roughly $1.25 million of the capital gain from tax entirely, and the remaining gain was taxed once, personally, at capital gains rates rather than being taxed first inside the corporation and again on distribution.

Set against the double-taxation exposure the original asset-sale structure would have created, and the risk of losing the exemption altogether if the passive assets had stayed in the company, the planning preserved roughly $400,000 to $900,000 that would otherwise have gone to tax rather than to Liang. Dimitri's side got the protections it needed through the representations, warranties, and holdback rather than through an asset purchase, and the deal closed within the timeline set out in the original letter of intent.

Yan's professional corporation was left untouched by the sale itself, but the coordinated timing meant the household avoided an unnecessarily large combined tax year, spreading dividend income from the medical practice across the years around the sale rather than concentrating it alongside the capital gain.
