Most business owners I talk to eventually start thinking about selling. Not necessarily this year, maybe not even this decade — but eventually it's on the table.

And when that conversation starts, the first question is almost always about valuation: what multiple will I get?

Fair question. But it's not the one that actually determines your outcome. The question that matters more is: what do I actually keep after tax? I've seen strong sale prices turn into disappointing results, not because the deal was bad, but because the tax planning started too late to do anything about it.

A Realistic Example

Let's call him David. He's 52, owns 100% of an HVAC services company in the GTA — installation, maintenance, and recurring service contracts for mid-sized commercial buildings. Over the last decade he's built a solid operation: $4.2 million in annual revenue, $900,000 in EBITDA, stable recurring maintenance contracts, and a small management team running day-to-day operations.

A private equity-backed consolidator comes calling and they land on a valuation of 5.5x EBITDA — $4.95 million.

Good number. On paper, a great outcome.

Without planning, here's what actually happens. David realizes a capital gain of roughly $4.7 million after adjusted cost base. He only has one Lifetime Capital Gains Exemption available — his own. The rest of the gain is fully taxable. The result is a meaningful chunk of his proceeds going to CRA, and a net number well below the $5 million he thought he was walking away with.

This is the moment I hear most often: "I thought I was getting five million, not this."

Step 1: Qualifying for the LCGE

To claim the LCGE, David's company needs to qualify as a Qualified Small Business Corporation. This is where a lot of owners get tripped up.

David's company has built up roughly $1.2 million in retained earnings and $600,000 sitting in a corporate investment account — ETFs and GICs. Prudent from a business standpoint. Problematic from a tax standpoint.

To qualify, at least 90% of the company's assets generally need to be used in an active business carried on primarily in Canada. On these numbers, David likely fails that test.

Step 2: Purification

The fix is usually a purification strategy — moving excess cash and investments into a holding company, paying out dividends, or reorganizing the balance sheet so the operating company actually clears the active-asset threshold.

The catch: this isn't a same-day fix. It typically needs real runway — often 24 months or more — to get the company into a position where it reliably meets the conditions at closing.

Step 3: Multiplying the Exemption with a Family Trust

Here's where it gets more interesting. If David had set up a family trust years earlier — with himself, his spouse, and his two adult children as beneficiaries — the gain on sale could potentially be allocated across all of them.

If each beneficiary independently qualifies for the LCGE, you're potentially looking at multiplying the exemption: at today's amount, roughly $1.25 million × 4 people = up to $5 million sheltered. That's not a rounding error — that can be the difference between a good outcome and a great one. It depends entirely on the structure being in place, and in place correctly, well before a deal is on the table.

The Two Scenarios, Side by Side

No planning: one LCGE claim, most of the gain taxable, proceeds materially reduced.

Planning done early: company purified and QSBC-eligible, family trust in place, gain allocated across multiple qualifying beneficiaries, a much larger portion sheltered, and meaningfully higher after-tax proceeds.

Same business. Same buyer. Same multiple. Very different after-tax result — and the difference was decided years before the sale, not at the closing table.

Why This Gets Missed

It's rarely because these strategies are obscure. It's usually because the conversation happens too late — advisors working in silos, the focus staying on growth rather than exit, and by the time a letter of intent is signed, the planning window has mostly closed.

The Takeaway

If you own a corporation, have growing retained earnings, and there's any realistic chance you sell in the next 3 to 10 years — this isn't just a tax question anymore. It's an exit planning question, and it needs to start now, not when you get the call from a buyer.

The biggest tax savings I've seen never come from last-minute maneuvering. They come from planning while there's still time to actually structure things properly.
