Key Takeaways
- 1.The $1,250,000 LCGE shelters the first $1.25M of capital gains on qualifying small business corporation shares — completely tax-free, saving approximately $445,000 in combined federal + BC tax.
- 2.After the LCGE, the remaining $1,750,000 capital gain is subject to the 2/3 inclusion rate (above the $250,000 annual threshold), producing approximately $1,125,000 in taxable income.
- 3.The BC combined top marginal rate of 53.50% (33% federal + 20.50% BC) applies to most of the taxable gain, resulting in approximately $553,000 in total personal tax on the share sale.
- 4.The Capital Dividend Account is relevant on an asset sale: the non-taxable 1/3 of the corporate capital gain ($1,000,000) can be paid to the shareholder completely tax-free via a subsection 83(2) election.
- 5.A share sale produces ~$2,447,000 in after-tax proceeds vs. ~$1,820,000 on an asset sale — a $627,000 gap driven by LCGE availability and corporate-level double taxation on the asset sale.
The Scenario: $3M Share Sale, BC Resident, Incorporated Consultant
This worked example models a common BC transaction: a sole-owner consultant who incorporated a CCPC years ago, built the practice to $3M in enterprise value, and is now selling the shares to a buyer. The corporation operates an active consulting business with minimal passive assets.
- Province of residence: British Columbia
- Sale structure: Share sale (seller sells 100% of issued shares)
- Sale price: $3,000,000
- Adjusted cost base (ACB) of shares: $100 (nominal incorporation cost)
- LCGE previously claimed: $0 (first-time use)
- Corporation type: Canadian-controlled private corporation (CCPC)
- Active business assets at time of sale: 95%+ by FMV (passes 90% test)
- Holding period: 8 years (passes 24-month test)
- 50% asset test: Active business assets exceeded 50% throughout prior 24 months
- Other personal income in 2025: $0 (sale is only income event)
Step 1: Establish the Capital Gain
The starting point is straightforward. The capital gain equals the proceeds of disposition minus the adjusted cost base of the shares:
Proceeds of disposition: $3,000,000
Less: ACB of shares: −$100
Capital gain: $2,999,900
For a consultant who incorporated with minimal share capital and never injected additional funds, the ACB is typically nominal. The entire sale price, less $100, is a capital gain.
Step 2: Apply the $1,250,000 LCGE
The Lifetime Capital Gains Exemption under section 110.6 of the Income Tax Act allows an individual to shelter up to $1,250,000 of capital gains on the disposition of qualifying small business corporation (QSBC) shares. This is a cumulative lifetime limit — any LCGE claimed on previous dispositions reduces the available room.
For the LCGE to apply, the shares must pass three tests at the time of sale:
| Test | Requirement | This Scenario |
|---|---|---|
| 90% asset test | At time of sale, 90%+ of assets (by FMV) used in active business in Canada | Pass — 95% active consulting assets |
| 24-month holding test | Shares owned by seller or related person for 24+ months | Pass — held 8 years |
| 50% asset test | Throughout prior 24 months, 50%+ of assets used in active business in Canada | Pass — active business throughout |
All three tests are met. The LCGE shelters $1,250,000 of the $2,999,900 gain:
Capital gain: $2,999,900
Less: LCGE: −$1,250,000
Remaining capital gain: $1,749,900
The $1,250,000 LCGE deduction saves approximately $445,000 in combined federal + BC tax (at the 2/3 inclusion rate and top marginal rates). This is the single largest tax lever in the entire transaction. For a similar analysis on an Ontario business sale, see our Ontario small business sale tax calculator with LCGE.
Common QSBC trap — the retained earnings problem. If a consulting corporation retains significant cash or investments from prior years' earnings, those passive assets can push the active business percentage below 90%. A corporation with $2.7M in goodwill but $500,000 in a corporate investment account only has 84% active assets — failing the 90% test. The fix is “purification”: paying out excess passive assets as dividends or repaying shareholder loans before the sale to restore the 90% ratio. This must be done before the share sale closes.
Step 3: Calculate the Taxable Capital Gain (2/3 Inclusion Rate)
Since June 25, 2024, capital gains realized by individuals above $250,000 per year are included in income at a 2/3 (66.67%) rate. The first $250,000 of annual capital gains (after LCGE) retains the 50% inclusion rate.
Remaining capital gain after LCGE: $1,749,900
First $250,000 × 50% inclusion = $125,000
Remaining $1,499,900 × 66.67% inclusion = $999,933
Total taxable capital gain: $1,124,933
This $1,124,933 is the amount included in the seller's personal income for 2025. It flows through the graduated federal and BC provincial tax brackets. For a deeper look at how the inclusion rate change affects investors, see our capital gains inclusion rate calculator for 2025.
Step 4: Federal + BC Tax on the Taxable Capital Gain
With $1,124,933 in taxable income and no other income sources, the tax calculation runs through every federal and BC bracket. The majority of the income lands in the top brackets.
Federal Tax (2025 Rates)
| Bracket | Rate | Taxable Amount | Tax |
|---|---|---|---|
| $0 – $57,375 | 15% | $57,375 | $8,606 |
| $57,375 – $114,750 | 20.5% | $57,375 | $11,762 |
| $114,750 – $158,468 | 26% | $43,718 | $11,367 |
| $158,468 – $221,708 | 29% | $63,240 | $18,340 |
| $221,708 – $1,124,933 | 33% | $903,225 | $298,064 |
| Gross federal tax | — | — | $348,139 |
| Less: basic personal credit (15% × $16,129) | — | — | −$2,419 |
| Net federal tax | — | — | $345,720 |
BC Provincial Tax (2025 Rates)
| Bracket | Rate | Taxable Amount | Tax |
|---|---|---|---|
| $0 – $47,937 | 5.06% | $47,937 | $2,426 |
| $47,937 – $95,875 | 7.70% | $47,938 | $3,691 |
| $95,875 – $110,076 | 10.50% | $14,201 | $1,491 |
| $110,076 – $133,664 | 12.29% | $23,588 | $2,899 |
| $133,664 – $181,232 | 14.70% | $47,568 | $6,992 |
| $181,232 – $252,752 | 16.80% | $71,520 | $12,015 |
| $252,752 – $1,124,933 | 20.50% | $872,181 | $178,797 |
| Gross BC tax | — | — | $208,311 |
| Less: basic personal credit (5.06% × $12,580) | — | — | −$637 |
| Net BC tax | — | — | $207,674 |
Total Tax and After-Tax Proceeds: Share Sale
Combined Tax on $3M Share Sale:
Net federal tax: $345,720
Net BC provincial tax: $207,674
Total estimated tax: $553,394
Sale proceeds: $3,000,000
Tax: −$553,394
After-tax proceeds: $2,446,606
Effective tax rate on $3M sale: 18.4%
Marginal rate on the top dollar of gain: 35.67% (53.50% × 2/3 inclusion)
The effective rate of 18.4% reflects the power of the LCGE. Without it, the tax bill would be approximately $998,000 — the LCGE saves roughly $445,000. The marginal rate on the last dollar of capital gain is 35.67% (the combined 53.50% top rate applied to the 2/3 inclusion portion).
The Capital Dividend Account: How It Works and When It Matters
The Capital Dividend Account is a notional account maintained by every CCPC. It tracks the non-taxable portion of capital gains (and certain other tax-free receipts like life insurance proceeds) realized by the corporation. The CDA balance can be paid out to shareholders as a tax-free capital dividend via an election under subsection 83(2) of the Income Tax Act.
On a share sale, the CDA is less directly relevant because the capital gain is personal — the corporation is not selling anything. However, any pre-existing CDA balance from historical corporate capital gains should be extracted as a capital dividend before closing, because the buyer inherits the CDA balance on a share purchase and the seller loses access to it.
On an asset sale, the CDA becomes a critical extraction mechanism. When the corporation sells its assets and realizes a capital gain, the non-taxable portion (1/3 under the current inclusion rate) is added to the CDA:
CDA Calculation on $3M Asset Sale:
Corporate capital gain on asset sale: $3,000,000
Non-taxable portion (1/3): $1,000,000
CDA balance addition: $1,000,000
This $1,000,000 can be elected as a capital dividend
and paid to the shareholder with $0 personal tax.
The CDA election must be filed with the CRA on Schedule 89 before or at the time the dividend is paid. Filing late or electing an amount exceeding the actual CDA balance triggers a 60% penalty tax on the excess under Part III of the Income Tax Act. Getting the CDA balance calculation right is not optional — it requires a precise audit of all historical capital gains, capital losses, and life insurance proceeds.
Share Sale vs. Asset Sale: The $627,000 Gap
The same $3M business can be sold as a share deal or an asset deal. The tax consequences are dramatically different. Here is the full comparison, showing why the seller almost always prefers shares and the buyer almost always prefers assets. For a similar Ontario comparison, see our Ontario share sale vs. asset sale calculator.
Asset Sale: Corporate-Level Tax, Then Dividend Extraction
In an asset sale, the corporation sells its business assets (goodwill, client contracts, equipment). The corporation realizes the capital gain, pays corporate tax, then the shareholder extracts the remaining funds as dividends before winding up the company.
| Step | Amount |
|---|---|
| Asset sale proceeds | $3,000,000 |
| Corporate capital gain (ACB ~$0) | $3,000,000 |
| Taxable capital gain (2/3 inclusion) | $2,000,000 |
| Corporate tax (~50.67% combined on investment income) | −$1,013,400 |
| RDTOH refund on dividend payout (~30.67%) | +$613,400 |
| Total distributable to shareholder | $2,600,000 |
| Capital dividend from CDA (tax-free) | $1,000,000 |
| Taxable dividend (non-eligible) | $1,600,000 |
| Personal tax on non-eligible dividend (~48.89% BC top rate) | −$780,000 |
| After-tax cash to shareholder | $1,820,000 |
Corporate tax rate reflects combined federal (38.67%, including refundable portion) and BC provincial (12%) on investment income in a CCPC. RDTOH (refundable dividend tax on hand) is refunded at $38.33 per $100 of taxable dividends paid. Non-eligible dividend rate is the BC combined top marginal rate. Figures are approximate.
Side-by-Side: Share Sale vs. Asset Sale
| Factor | Share Sale | Asset Sale |
|---|---|---|
| Sale price | $3,000,000 | $3,000,000 |
| LCGE available? | Yes — $1,250,000 | No (corporate gain) |
| CDA extraction | Pre-existing only | $1,000,000 (new) |
| Total tax (all levels) | ~$553,000 | ~$1,180,000 |
| After-tax proceeds | ~$2,447,000 | ~$1,820,000 |
| Difference | ~$627,000 in favor of share sale | |
The $627,000 gap is driven by two factors: the LCGE (worth ~$445,000 in tax savings) is only available on a share sale, and the asset sale triggers double taxation (corporate tax + personal dividend tax) that the integration system does not fully eliminate. Even with the CDA extracting $1,000,000 tax-free, the asset sale cannot close the gap.
In practice, buyers often negotiate a purchase price adjustment to share part of the seller's tax savings — offering a lower share price but still leaving the seller better off than an asset deal. A $200,000 price reduction to $2.8M on a share sale still leaves the seller with approximately $2,290,000 after tax, well above the $1,820,000 from the asset sale.
Planning Levers to Reduce the Tax Further
Multiply the LCGE With a Family Trust
If the shares had been held in a family trust with the seller's spouse and adult children as beneficiaries, the trust could allocate capital gains to multiple beneficiaries, each claiming their own $1,250,000 LCGE. A family of four could shelter up to $5,000,000 in capital gains — more than enough to eliminate tax on the entire $3M sale. This requires advance planning (the trust must have held the shares for 24+ months) and cannot be implemented at the time of sale. For related family business planning, see our family business LCGE calculator for a $2M sale.
Use a Capital Gains Reserve to Spread the Gain
If the buyer pays over time (vendor take-back financing), the seller can claim a capital gains reserve under section 40(1)(a)(iii), deferring recognition of the gain over up to five years. This can shift portions of the $1,749,900 post-LCGE gain into future years, potentially benefiting from multiple years of the $250,000 lower-inclusion threshold and lower graduated bracket rates. For a detailed walkthrough, see our capital gains reserve calculator for vendor-financed sales.
Purify the Corporation Before Sale
If the corporation holds passive investments that risk failing the 90% asset test, the seller must “purify” before closing. Common purification strategies include paying out excess cash as dividends, repaying shareholder loans, purchasing life insurance (the cash surrender value is an active business asset if certain conditions are met), or transferring passive assets to a holding company via a section 85 rollover. Purification must be completed before the share sale closes to preserve LCGE eligibility.
Extract the Pre-Existing CDA Before a Share Sale
If the corporation has historical capital gains from investments or asset dispositions during its operating life, the accumulated CDA balance should be paid out as a capital dividend before the share sale closes. Once the buyer acquires the shares, the buyer — not the seller — controls the CDA. Filing the Schedule 89 election and paying the capital dividend pre-closing is a straightforward step that is easily overlooked.
