Share Sale vs Asset Sale
The two legal structures for selling a business. A share sale transfers ownership of the entire corporation; an asset sale transfers specific assets, rights, or contracts. Each structure carries very different tax, legal, and operational consequences.
Definition
When an owner sells a business, the transaction generally takes one of two forms:
Share sale: the seller sells their shares in the corporation. The buyer becomes the owner of the existing corporation with everything it holds — assets, contracts, employees, but also liabilities and history.
Asset sale: the seller sells specific assets of the business (equipment, inventory, customer base, trade name, certain contracts, and so on). The corporation itself usually stays with the seller.
In French-language Quebec documentation, you’ll see vente d’actions vs vente d’actifs used for the same concept.
Why this distinction is fundamental
The structure of the transaction directly affects what the seller keeps after tax, and also the level of risk the buyer accepts.
Advantages of a share sale (for the seller)
- Potential access to capital gains treatment and, if the conditions are met, to the Lifetime Capital Gains Exemption
- Simpler continuity of certain contracts, permits, and relationships, though consents may still be required
- The seller walks away from the corporation directly, with its historical assets and liabilities
Advantages of an asset sale (for the buyer)
- The buyer picks more precisely what they’re buying
- They can try to exclude problematic liabilities
- They may benefit from more favourable future tax treatment on certain acquired assets
The structural conflict of interest
Sellers often prefer shares for tax reasons. Buyers often prefer assets for risk reasons. Negotiating between the two is therefore a central piece of any transaction.
The best structure doesn’t depend on tax alone. It also depends on historical liabilities, the nature of the assets, licences and permits, how easily contracts can be transferred, and what the lender is willing to finance.
What every seller should know
- The share vs asset question should be discussed with your tax advisor before offers come in — not after
- In Quebec SMEs, share sales are common, but every situation is unique
- Price can be adjusted to offset the tax disadvantage of a given structure — it’s often a central point of negotiation
- A share sale isn’t automatically better for the seller, and an asset sale isn’t automatically worse — it all depends on net after tax, risk transferred, and legal terms
