How to Handle Shareholder Buyouts in a Canadian Private Company: A Complete Income Tax Decision Tree
If you’re a shareholder or business owner in a Canadian private company considering a buyout, understanding the tax implications is critical. Shareholder buyouts can be complex because the tax treatment depends on who is buying the shares and the transaction structure.
This blog post breaks down the tax scenarios for shareholder buyouts in private companies, explaining key concepts like Paid-Up Capital (PUC), Adjusted Cost Base (ACB), and relevant tax rules. Plus, you’ll find a handy interactive decision tree tool to help you identify the right tax treatment for your situation.
What Is a Shareholder Buyout?
A shareholder buyout happens when one or more shareholders exit the company by selling or redeeming their shares. In private companies, buyouts usually happen in two ways:
Share Redemption by the Corporation: The company repurchases shares directly from the shareholder.
Share Transfer to Another Person or Corporation: The shareholder sells their shares privately to another party.
Each method has distinct tax consequences under Canadian law.
Scenario 1: Share Redemption by the Corporation (Corporation Buyout)
When a corporation buys back its own shares from a shareholder, this is called a share redemption. Unlike a sale to a third party, the company repurchases shares directly, reducing the number of shares outstanding.
Tax Implications:
| Scenario | Tax Treatment | Notes |
|---|---|---|
| Redemption price ≤ Paid-Up Capital (PUC) | Tax-free return of capital | PUC reduced accordingly |
| Redemption price > Paid-Up Capital (PUC) | Deemed dividend on excess amount | Corporation issues T5 slip; dividend taxable |
| Redemption price > Adjusted Cost Base (ACB) but ≤ PUC | Capital gain on excess over ACB; PUC portion is return of capital | Capital gains may qualify for LCGE if QSBC shares |
| Redemption price < Adjusted Cost Base (ACB) | Capital loss | Capital losses can offset capital gains |
Paid-Up Capital (PUC): Represents the shareholder’s equity contribution to the company. Return of capital up to PUC is not taxable.
Adjusted Cost Base (ACB): The original cost of shares adjusted for certain transactions, used to calculate capital gains or losses.
Reporting:
Corporation must issue a T5 slip for any deemed dividend portion.
Shareholder reports deemed dividend as income and capital gain/loss on personal tax return.
Properly identifying PUC and ACB prevents unexpected tax liabilities and helps plan tax-efficient buyouts.
Scenario 2: Share Sale to Another Person or Corporation (Private Transfer)
Here, the shareholder sells their shares to another individual or corporation, not involving the company itself.
Tax Implications:
The difference between proceeds of disposition and ACB (minus selling costs) results in a capital gain or loss.
If shares qualify as Qualified Small Business Corporation (QSBC) shares, the seller may claim the Lifetime Capital Gains Exemption (LCGE), which can shelter up to $971,190 (2025 amount) of capital gains from tax.
Selling to an arm’s length party means regular capital gains rules apply.
Key Points:
Capital gains receive preferential tax rates compared to dividend income.
Selling costs (legal, broker fees) reduce proceeds for capital gain calculation.
Scenario 3: Related-Party Sales and Anti-Avoidance Rules
If the shares are sold to a related party, such as a corporation controlled by the seller or a family member, special rules under Section 84.1 of the Income Tax Act may apply to prevent tax avoidance, often called “surplus stripping”.
Tax Implications:
Capital gains may be recharacterized as deemed dividends, which are taxed at higher personal income tax rates.
This anti-avoidance provision is designed to prevent converting dividend income into lower-taxed capital gains improperly.
Careful tax planning and professional advice are essential to navigate these transactions.
