The way you sell your business can change your tax bill by hundreds of thousands of dollars. In Canada the two routes — a share sale and an asset sale — are taxed completely differently, and a recent increase to the lifetime capital gains exemption makes the planning more valuable than ever in 2026. Here's what every Canadian business owner should understand before they sell.
If your business is incorporated, a buyer can purchase either the shares of your corporation or the assets inside it. Sellers almost always prefer a share sale; buyers usually prefer an asset sale. The tax consequences are the reason.
In a share sale you sell the company shares and realize a capital gain (only 50% of which is taxable — the proposed increase to 66.7% was cancelled, so the inclusion rate stays at 50% for 2026). The big advantage: if your shares are Qualified Small Business Corporation (QSBC) shares, you may shelter a large chunk of the gain with the Lifetime Capital Gains Exemption (LCGE).
The LCGE rose to $1,250,000 and is now indexed to inflation — roughly $1,275,000 for 2026. That can mean over a million dollars of gain entirely tax-free. See our dedicated guide to the lifetime capital gains exemption for the full mechanics.
In an asset sale the corporation sells its assets (equipment, goodwill, inventory) and keeps the shell. This creates tax inside the corporation — including recapture of previously claimed capital cost allowance and capital gains on goodwill — and then a second layer of tax when you extract the proceeds personally as dividends. Asset sales also don't qualify for the LCGE on the operating assets.
| Share sale | Asset sale | |
|---|---|---|
| Who's taxed | You (personally) | Corporation, then you |
| Capital gains exemption | Yes (if QSBC) | No (on operating assets) |
| CCA recapture | No | Yes |
| Layers of tax | One | Two |
| Typically preferred by | Seller | Buyer |
QSBC status isn't automatic. To claim the exemption your shares generally must meet three tests:
"Purification" — removing excess passive assets and cash from the company before a sale — is often needed to pass these tests. That planning takes time, so it should start well before you list the business. Investment-heavy corporations should also review our guide to passive investment income.
The difference between a well-structured share sale and an unplanned asset sale can be six figures. Purification, multiplying the LCGE among family members, and the share-vs-asset negotiation all need to happen before the deal closes. Our Calgary corporate tax and tax planning teams help owners structure exits years in advance.
Sellers usually prefer a share sale because it's taxed as a single capital gain and may qualify for the lifetime capital gains exemption. Buyers usually prefer an asset sale for liability and depreciation reasons. A share sale is generally far more tax-efficient for the seller, but the final structure is negotiated.
If your shares are Qualified Small Business Corporation shares, the lifetime capital gains exemption can shelter up to about $1,275,000 of gain for 2026 (the exemption rose to $1.25 million and is now indexed). The capital gains inclusion rate remains 50%.
The lifetime capital gains exemption increased to $1,250,000 and is indexed to inflation, giving roughly $1,275,000 for 2026 on qualifying dispositions of small business corporation shares and qualified farm or fishing property.
Your shares must generally meet three tests: the corporation is a small business corporation at the time of sale (about 90%+ active business assets), you held the shares for at least 24 months, and more than 50% of assets were used in active business throughout that period. "Purifying" excess passive assets before the sale is often required, so plan early.
