Qualified Small Business Corporation Shares Guide Canada 2025

Updated March 2025 · 11 min read

Qualified Small Business Corporation (QSBC) shares are shares that meet specific conditions under the Income Tax Act, making them eligible for the Lifetime Capital Gains Exemption (LCGE). In 2025, the LCGE for QSBC shares is $1,250,000 per individual — one of the most valuable tax benefits available to Canadian entrepreneurs.

Understanding whether your shares qualify — and what to do if they don't — is essential planning for any business owner considering a future sale.

What Is a Qualified Small Business Corporation?

A Qualified Small Business Corporation is a Canadian-controlled private corporation (CCPC) that meets specific asset tests. The QSBC definition is found in subsection 110.6(1) of the Income Tax Act. The key requirement is that all or substantially all (interpreted by CRA as 90% or more) of the fair market value of the corporation's assets must be attributable to:

• Assets used principally in an active business carried on primarily in Canada by the corporation or a related corporation, or
• Shares or debt of connected corporations that are themselves small business corporations, or
• A combination of the above

The Three Tests for QSBC Shares

To claim the LCGE on a sale of shares, the shares must meet three tests — not just the QSBC test at the time of sale:

Test 1: Small Business Corporation at Time of Sale

At the time of sale, the corporation must be a CCPC where 90%+ of the FMV of assets is in active business assets (or shares/debt of connected SBCs). This is the QSBC test. Passive assets — investment portfolios, excess cash, non-business real estate — count against this 90% threshold.

Test 2: 24-Month Ownership and Asset Tests

Throughout the 24 months immediately before the sale, two conditions must be met continuously:

• The shares must have been owned only by the individual claiming the LCGE or a person related to them
• More than 50% of the FMV of the corporation's assets must have been used in an active business carried on primarily in Canada

This 24-month test prevents last-minute reorganizations to qualify shares for the exemption.

Test 3: Canadian Residency

The individual selling the shares must be a Canadian resident throughout the year of sale (with some exceptions for the year of departure from Canada).

What Counts as Active Business Assets?

Assets used in an active business include:

• Accounts receivable from business operations
• Inventory
• Equipment and machinery used in the business
• Real property used in the active business (office, warehouse, manufacturing facility)
• Prepaid expenses related to the business
• Cash required for working capital of the business (though excess cash is passive)
• Intangibles like patents, trademarks, customer lists used in the business

What Counts as Passive Assets (and Hurts Qualification)?

• Investment portfolios (stocks, bonds, GICs, mutual funds not related to the business)
• Excess cash beyond what's needed for business operations
• Real estate not used in the active business (rental properties, vacant land)
• Long-term notes receivable not arising from business sales
• Loans to shareholders or related parties

Purification: Getting Your Shares to Qualify

If your corporation fails the 90% active assets test due to accumulated passive assets, you need to "purify" it — remove or reduce the passive assets — and then let the 24-month clock run before a sale.

Common purification strategies:

Pay Out Excess Assets

Declare dividends to distribute excess cash or investment assets out of the corporation to shareholders. After distribution, the corporation's asset mix shifts back toward active business assets. Be mindful of the tax cost — dividends paid to shareholders are taxable income.

Invest in Business Assets

Use excess cash to purchase business assets — equipment, business real estate, prepay business expenses, or fund business expansion. This shifts the asset mix without triggering tax.

Corporate Reorganization

Transfer passive assets to a separate holding company using a tax-deferred rollover, leaving the active business and its assets in a clean operating company. After 24 months of clean operation, the opco shares qualify for the LCGE.

Pay Down Business Debt

Using excess cash to retire business-related debt reduces passive assets (cash) and improves the business asset ratio.

QSBC Shares Through a Family Trust

When QSBC shares are held through a family trust, the shares themselves must meet the QSBC conditions at the time of sale. Capital gains realized by the trust and allocated to beneficiaries allow each beneficiary to use their own LCGE — subject to the beneficiary meeting the residency and other personal eligibility conditions.

The 24-month ownership test for trust-held shares is met if the trust (not an arm's length party) has held the shares for 24 months and the 50%+ active asset test was met throughout. Specific rules govern when the trust's holding period begins.

Impact of the 2024 Capital Gains Inclusion Rate Change

The 2024 federal budget increased the capital gains inclusion rate from 50% to 66.67% on gains above $250,000 per year for individuals. Gains sheltered by the LCGE are exempt regardless — the LCGE shelters the capital gain entirely, so the inclusion rate change doesn't reduce its value. In fact, the higher inclusion rate increases the absolute tax saving from using the LCGE.

Common Mistakes That Disqualify the LCGE

• Failing to purify the corporation before the 24-month clock
• Selling shares to an arm's length party within 24 months of a related party transaction that affected share ownership
• Not maintaining the 90% active assets test throughout the 24-month period (investing business cash in passive investments during this period)
• Ignoring the CNIL (Cumulative Net Investment Loss) balance which can reduce available LCGE
• Structuring the sale as an asset sale rather than a share sale (only share sales qualify for the LCGE)

Professional Advice Is Essential

QSBC qualification is technical and fact-specific. The difference between qualifying and not qualifying for the full LCGE can be $300,000 or more in tax on a business sale. Engage a CPA with corporate tax expertise well before any planned sale — ideally three to five years in advance to allow time for purification and the 24-month holding period if needed.
