Key Takeaways
- 1.A single shareholder selling $2M of QSBC shares can shelter $1.25M with the LCGE, leaving $750K of taxable capital gains — roughly $195,000 in combined federal and Quebec tax.
- 2.If husband and wife each own 50% and both claim their $1.25M LCGE, the entire $2M gain is fully sheltered — total tax on the share sale drops to $0.
- 3.The 90% active-asset test must be met at the time of sale — passive investments, excess cash, or corporate GICs can disqualify the entire exemption if they push active assets below the threshold.
- 4.Quebec mirrors the federal LCGE with its own provincial capital gains deduction, meaning the exemption shelters both federal and Quebec tax on qualifying gains.
The Scenario: Selling a Quebec Family Business for $2M in 2025
Here are the baseline assumptions for our worked example. The methodology applies to any QSBC share sale in Canada, but the provincial tax numbers are specific to Quebec:
| Detail | Value |
|---|---|
| Sale price of shares | $2,000,000 |
| Adjusted cost base (ACB) of shares | $100 (nominal incorporation cost) |
| Capital gain | $1,999,900 (≈ $2,000,000) |
| 2025 LCGE limit per individual | $1,250,000 |
| LCGE previously used | $0 |
| Province of residence | Quebec |
| Shareholder's other income | $80,000 salary |
| Shares held for | 20 years (well past 24-month test) |
| Active business assets at time of sale | 92% of FMV (passes 90% test) |
The ACB of family business shares is often negligible — many owner-managers incorporated for $100 decades ago. The entire sale price is effectively a capital gain, which is why the LCGE is so critical for these transactions.
Scenario 1: Single Shareholder Sells All Shares
If one spouse owns 100% of the shares and sells for $2M, only one LCGE is available. Here is the tax calculation for a Quebec resident:
| Component | Amount |
|---|---|
| Total capital gain | $2,000,000 |
| LCGE claimed | $1,250,000 |
| Remaining taxable capital gain | $750,000 |
| Inclusion rate — first $250K (1/2) | $125,000 |
| Inclusion rate — remaining $500K (2/3) | $333,333 |
| Total taxable amount added to income | $458,333 |
| Federal tax on $458,333 (at top marginal ~33%) | ~$139,000 |
| Quebec provincial tax (~25.75% top rate) | ~$106,000 |
| Quebec abatement (16.5% federal reduction) | −$23,000 |
| Approximate total tax on share sale | ~$195,000 |
Note the two-tier capital gains inclusion rate that took effect June 25, 2024: the first $250,000 of capital gains above the LCGE is included at 50%, and anything beyond that is included at 66.67%. For this $750K excess gain, the blended inclusion rate works out to roughly 61%. The Quebec abatement reduces federal tax for Quebec residents since Quebec collects its own income tax separately.
Scenario 2: Husband and Wife Each Sell 50% of Shares
If the shares were split 50/50 between spouses at least 24 months before the sale, each spouse realizes a $1,000,000 capital gain — well within the $1.25M LCGE limit:
| Component | Husband | Wife |
|---|---|---|
| Capital gain on share sale | $1,000,000 | $1,000,000 |
| LCGE claimed | $1,000,000 | $1,000,000 |
| Taxable capital gain | $0 | $0 |
| LCGE remaining for future use | $250,000 | $250,000 |
| Tax on share sale | $0 | $0 |
Single vs Split Shareholder: Net Savings
- Single shareholder: $2M sale − ~$195,000 tax = ~$1,805,000 after tax
- 50/50 spousal split: $2M sale − $0 tax = $2,000,000 after tax
- Tax savings from splitting: ~$195,000
The $195,000 difference is entirely from doubling the available LCGE. Each spouse also retains $250,000 of unused LCGE for future qualifying dispositions — a combined $500,000 of future tax-free room. This is the single most powerful tax planning tool available for Canadian family business owners. For context on how this fits into retirement planning, see the Retirement Calculator.
The 90% Active-Asset Test: Where Most Sales Get Derailed
The LCGE only applies to qualified small business corporation shares. At the moment of sale, at least 90% of the corporation's assets (by fair market value) must be used in an active business carried on primarily in Canada. This is the test that catches the most business owners off guard.
Consider a company with $2M in total fair market value of assets:
| Asset | FMV | Classification |
|---|---|---|
| Equipment and inventory | $800,000 | Active |
| Accounts receivable | $300,000 | Active |
| Business real estate | $500,000 | Active |
| Goodwill | $200,000 | Active |
| Corporate GIC portfolio | $120,000 | Passive |
| Excess cash in bank | $80,000 | Passive |
| Total | $2,000,000 | Active: 90% | Passive: 10% |
At exactly 90% active, this company barely passes the test. If the GIC portfolio had been $140,000 instead of $120,000, the active ratio would drop to 89% and the entire LCGE would be lost — not just the portion attributable to passive assets, but all of it. This is an all-or-nothing threshold.
Purification Strategies: Getting to 90%
If your company holds too many passive assets, you need to purify the balance sheet before selling. The most common strategies:
- Pay out excess cash as dividends: Declare a special dividend to the shareholders before the sale. This removes passive cash from the corporation but creates taxable dividend income — eligible dividends are taxed at roughly 39% combined in Quebec at the top bracket, so the cost-benefit must be calculated carefully.
- Repay shareholder loans: If the corporation owes money to the shareholders (a common structure in family businesses), repaying the loan removes cash from the company without triggering a taxable event.
- Purchase active business assets: Buying equipment, inventory, or other assets used in the business increases the active percentage. However, the CRA may challenge purchases made solely to meet the 90% test.
- Transfer passive assets to a holding company: A section 85 rollover can move investment portfolios to a separate holding company on a tax-deferred basis, leaving the operating company clean for the QSBC test. This is the most common professional strategy but requires careful legal structuring.
Timing is critical: the 90% test must be met at the moment of sale. But remember the 24-month holding period test requires only 50% active assets throughout the prior two years. A purification done one week before closing can satisfy the 90% test, provided the 50% test has been met for the preceding 24 months.
Quebec Provincial Deduction Stack
Quebec residents file a separate provincial return (TP-1) from their federal return. The LCGE shelters capital gains at both levels, but the mechanics are slightly different:
| Tax Level | Mechanism | Effect on $1M Gain (Split Scenario) |
|---|---|---|
| Federal | Capital gains deduction (Section 110.6) | $1M sheltered — $0 federal tax on gain |
| Quebec | Capital gains deduction (mirrored) | $1M sheltered — $0 Quebec tax on gain |
| Quebec health contribution | Based on total income including gains | May still apply if total income exceeds thresholds |
| Federal abatement for Quebec | 16.5% reduction of basic federal tax | Reduces federal tax on non-sheltered income |
The Quebec health contribution is a detail many forget. Even when the LCGE fully shelters the capital gain for income tax purposes, the gain may still increase net income used to calculate the health contribution. For the 50/50 split scenario, the impact is minimal since each spouse's gain is fully offset by the deduction. For the single-shareholder scenario, the $458,333 taxable portion pushes into the highest health contribution bracket. To model how salary and investment income interact in Quebec, use the CRA Tax Estimator.
The 24-Month Holding Period: Planning Ahead
The LCGE requires shares to have been held for at least 24 months before the sale. For a family business that has been owned for 20 years, this is trivially satisfied by the founding shareholder. The issue arises when splitting shares with a spouse for the first time.
If you transfer 50% of your shares to your spouse today, they cannot sell those shares with LCGE protection for another 24 months. This means the share-splitting strategy must be planned at least two years before a potential sale. A share reorganization done in January 2025 enables a qualifying sale no earlier than January 2027.
The transfer itself can be done on a tax-deferred basis using a section 85 rollover or an estate freeze, where new shares are issued to the spouse and the original shares are frozen at their current value. This is standard family business succession planning — your accountant and lawyer will structure it to avoid triggering any immediate tax.
TOSI Rules: The Anti-Income-Splitting Backstop
The tax on split income (TOSI) rules introduced in 2018 were designed to prevent exactly this kind of income splitting. However, there are important exemptions:
- Capital gains on QSBC share dispositions are excluded from TOSI for individuals aged 18 and over. This is a specific carve-out that preserves the spousal LCGE splitting strategy for share sales.
- Dividends paid to a spouse who is not actively involved in the business may be subject to TOSI and taxed at the top marginal rate. This is why purification via dividends needs careful consideration — the dividends themselves may face punitive TOSI treatment.
- The excluded business exception applies if the spouse was actively engaged in the business on a regular, continuous, and substantial basis in the year or in any 5 prior years. Meeting this test removes TOSI concerns entirely for both dividends and capital gains.
For most family businesses where both spouses have been actively involved, TOSI is not a barrier. Where it becomes an issue is when shares are gifted to a spouse who has never worked in the business solely for the purpose of accessing their LCGE. The CRA has challenged these arrangements, and the general anti-avoidance rule (GAAR) adds another layer of risk.

Complete Tax Comparison: Single vs Split
Here is the full side-by-side showing the combined federal and Quebec tax impact of each scenario, assuming the $80,000 salary and no prior LCGE usage:
| Factor | Single Shareholder | 50/50 Split |
|---|---|---|
| Total capital gain | $2,000,000 | $1,000,000 each |
| LCGE claimed | $1,250,000 | $1,000,000 each ($2M total) |
| Remaining gain subject to tax | $750,000 | $0 |
| Taxable capital gain (inclusion) | $458,333 | $0 |
| Federal tax (after Quebec abatement) | ~$116,000 | $0 |
| Quebec provincial tax | ~$106,000 | $0 |
| Quebec health contribution (incremental) | ~$1,000 | $0 |
| Total tax on share sale | ~$195,000 | $0 |
| After-tax proceeds | ~$1,805,000 | $2,000,000 |
| Remaining LCGE for future use | $0 | $250,000 each |
The split scenario is unambiguously better: $195,000 in tax savings plus $500,000 of combined unused LCGE for future qualifying dispositions. The only cost is the legal and accounting fees for the share reorganization (typically $3,000–$8,000) and the requirement to plan at least 24 months in advance. For most family businesses worth $1M or more, this is the highest-return tax planning available.
What If You Have Already Used Some LCGE?
The $1.25M LCGE is a lifetime limit, not a per-transaction limit. If you claimed $400,000 of LCGE on a previous QSBC share sale or qualifying farm property disposition, only $850,000 remains available. In a $2M sale:
| Scenario | LCGE Available | Tax on $2M Sale |
|---|---|---|
| Full LCGE, single shareholder | $1,250,000 | ~$195,000 |
| $400K used, single shareholder | $850,000 | ~$310,000 |
| Full LCGE, 50/50 split | $2,500,000 combined | $0 |
| One spouse used $400K, 50/50 split | $2,100,000 combined | $0 |
Even with partial prior usage, the spousal split still fully shelters a $2M sale because the combined remaining LCGE ($2.1M) exceeds the total gain. The math only gets tight when both spouses have significant prior LCGE claims, or when the sale price exceeds $2.5M. For understanding how investment income interacts with registered accounts, see RRSP vs TFSA Comparison.
The Canadian Entrepreneurs' Incentive: An Additional $2M Exemption
Starting in 2025, the federal government introduced the Canadian Entrepreneurs' Incentive (CEI), which provides an additional lifetime capital gains exemption on qualifying share dispositions. The CEI is being phased in gradually — the 2025 limit is $400,000, increasing by $200,000 annually until reaching $2,000,000 in 2032.
The CEI applies a reduced inclusion rate of one-third (33.33%) rather than fully exempting the gain. This means for every dollar of gain covered by the CEI, the taxable amount is 33.33 cents instead of 50 or 66.67 cents under the regular inclusion rates. The CEI stacks on top of the LCGE — you use the LCGE first (full exemption), then the CEI applies to additional gains at the reduced inclusion rate.
For our $2M single-shareholder scenario in 2025, the CEI could shelter an additional $400,000 at the reduced rate, lowering the tax bill further. However, the CEI has its own qualifying conditions and is not available for all QSBC dispositions. To estimate the combined impact of the LCGE and CEI on your specific sale, try the Canadian Federal Tax Calculator.
Step-by-Step: Preparing a Family Business Sale for LCGE
For a Quebec family business targeting a sale in 2027, here is the recommended timeline:
- 24+ months before sale (early 2025): Implement share reorganization — issue new shares to spouse via estate freeze or section 85 rollover. Start the 24-month holding period clock.
- 12 months before sale: Review the corporate balance sheet. Identify all passive assets. Begin purification if passive assets exceed 10% of FMV — pay dividends, repay shareholder loans, or transfer investments to a holdco.
- 6 months before sale: Obtain a formal business valuation. The valuation establishes the 90% active-asset ratio and supports the sale price for CRA review. Confirm both spouses meet the excluded business exception or that the TOSI carve-out for QSBC dispositions applies.
- At closing: Ensure the 90% test is met on the date of sale. File capital gains deduction claims (T657 federally, TP-726.7 for Quebec) with the tax returns for the sale year.
- Tax filing year: Each spouse files their own return claiming their portion of the capital gain and the corresponding LCGE deduction. The T2 corporate return reflects the share disposition.
Common Mistakes That Disqualify the LCGE
These are the errors we see most often in family business sales:
- Failing to purify in time: Passive investments accumulated over years push the company below the 90% threshold. The fix is straightforward but must be done before the sale closes.
- Transferring shares too late: Splitting shares with a spouse less than 24 months before sale means those shares do not qualify — only the original shareholder can claim the LCGE on the transferred portion.
- Selling assets instead of shares: The LCGE applies to shares, not to asset sales. If the buyer insists on an asset purchase, the vendor cannot claim the LCGE. This is often the most significant negotiation point in a family business sale — share deals save the vendor hundreds of thousands, while asset deals give the buyer better CCA pools. For an example of how CCA affects asset purchases, see our article on Rental Property Depreciation.
- Ignoring the cumulative net investment loss (CNIL): If you have accumulated net investment losses (investment expenses exceeding investment income over your lifetime), your LCGE is reduced dollar-for-dollar by the CNIL balance. Large interest deductions on investment loans can erode the exemption without you realizing it.
- Not filing T657/TP-726.7: The LCGE is not automatic. You must claim it by filing the appropriate forms with your tax return. Missing the filing means paying tax now and amending later — a process that can take years.
