Key Takeaways
- 1.The share deal shelters $1,016,836 of the $1.5M gain under the 2025 LCGE — the remaining $484K faces personal capital gains tax, netting approximately $1,355,000–$1,370,000 after tax.
- 2.The asset deal triggers corporate tax on the full $1.5M gain (~$380K), then personal tax on distribution of the after-tax proceeds — netting approximately $930,000–$970,000 after all taxes.
- 3.The tax gap between share and asset deal is roughly $390,000–$430,000 on a $1.5M gain — driven entirely by LCGE availability and the absence of double taxation.
- 4.The 2025 LCGE of $1,016,836 is inflation-indexed annually. It applies per individual, so spousal share ownership can double the shelter to ~$2.03M.
- 5.On the share deal, the capital dividend account (CDA) allows tax-free extraction of the non-taxable portion of the excess gain — reducing the effective rate on the $484K residual.
The Setup: $1.5M Capital Gain on an Ontario Business
An Ontario resident owns 100% of the shares of a Canadian-controlled private corporation (CCPC) that qualifies as a small business corporation. The shares have an adjusted cost base (ACB) of $1 and a fair market value of $1,500,001 — producing a $1.5M capital gain on disposition. The owner has never previously used any LCGE. The corporation carries on an active business in Ontario, holds no significant passive investments, and meets all QSBC qualification tests.
The question: sell shares to the buyer, or have the corporation sell its assets? The buyer may prefer an asset deal (for the step-up in cost base on depreciable property and the ability to cherry-pick assets). The seller almost always prefers a share deal. The tax math below explains why. For related reading on how the LCGE works in Quebec, see our LCGE calculator for a $2M Quebec business sale.
Path 1: Share Deal — LCGE Shelters $1,016,836
In a share deal, the individual shareholder sells their shares directly to the buyer. The capital gain is realized personally, which means the lifetime capital gains exemption is available.
Step 1: Apply the LCGE
Capital gain on share sale: $1,500,000
2025 LCGE available: $1,016,836
Gain sheltered by LCGE: $1,016,836 (zero tax)
Residual gain: $1,500,000 − $1,016,836 = $483,164
The LCGE eliminates $1,016,836 of the gain entirely — it is not included in income, not reported as a taxable capital gain, and generates no tax liability. The remaining $483,164 is subject to the 2025 capital gains inclusion rules.
Step 2: Capital Gains Inclusion on the $483,164 Residual
Under the 2025 rules, an individual's first $250,000 of capital gains in a tax year is included at 50%. Gains above $250,000 are included at 66.7%. The LCGE-sheltered portion does not count toward the $250,000 threshold — only the taxable gain matters.
Residual capital gain: $483,164
First $250,000 at 50% inclusion: $125,000 taxable
Remaining $233,164 at 66.7% inclusion: $155,520 taxable
Total taxable capital gain: $125,000 + $155,520 = $280,520
Step 3: Federal and Ontario Tax on $280,520 Taxable Income
Assuming no other income in the year of sale (simplified), the $280,520 in taxable capital gain is the entire taxable income:
Federal tax on $280,520:
$57,375 at 15% = $8,606
$57,375 at 20.5% = $11,762
$63,317 at 26% = $16,462
$51,281 at 29% = $14,871
$51,172 at 33% = $16,887
Federal tax before credits: $68,588
Basic personal amount credit: −$2,499
Net federal tax: ~$66,089
Ontario tax on $280,520:
$51,446 at 5.05% = $2,598
$51,454 at 9.15% = $4,708
$47,100 at 11.16% = $5,256
$130,520 at 12.16% = $15,871
Ontario surtax (20% on provincial tax above $4,991
+ 36% on provincial tax above $6,387): ~$7,200
Ontario tax before credits: ~$35,633
Basic personal amount credit: −$572
Net Ontario tax: ~$35,061
Total tax on share deal: ~$101,150
After-tax proceeds: $1,500,000 − $101,150 = ~$1,398,850
The effective tax rate on the full $1.5M gain is approximately 6.7%. On the $483,164 residual alone, the effective rate is roughly 21%. Compare this to the capital gains inclusion rate calculator for how the two-tier inclusion system affects investment gains generally.
Path 2: Asset Deal — No LCGE, Corporate-Level Gain
In an asset deal, the corporation sells its business assets (goodwill, equipment, inventory, customer contracts) to the buyer. The corporation — not the individual — realizes the $1.5M capital gain. Because the LCGE is only available to individuals disposing of qualifying shares, it cannot be used. The gain is taxed first inside the corporation, then again when the after-tax proceeds are distributed to the shareholder.
Step 1: Corporate Tax on the $1.5M Gain
For corporations, there is no $250,000 threshold — the entire capital gain is included at 66.7%. The non-taxable portion (33.3%) flows to the capital dividend account.
Capital gain realized by corporation: $1,500,000
Taxable capital gain (66.7%): $1,000,500
Non-taxable portion to CDA (33.3%): $499,500
Corporate tax on $1,000,500:
Refundable Part IV / Part I tax on investment income
(capital gains in a CCPC are treated as aggregate
investment income — refundable tax applies):
Federal rate on investment income: 38.67%
(includes 10.67% refundable portion)
Ontario rate on investment income: 11.5%
Combined rate: ~50.17%
Corporate tax: $1,000,500 × 50.17% = ~$501,750
Refundable dividend tax on hand (RDTOH): ~$107,153
(refunded when taxable dividends paid out)
Net corporate tax after RDTOH refund: ~$394,597
Cash remaining in corporation:
$1,500,000 − $394,597 = ~$1,105,403
Step 2: Extracting Proceeds — Capital Dividend + Taxable Dividend
The shareholder needs to extract the after-tax proceeds from the corporation. Two streams are available:
Stream 1: Tax-free capital dividend from CDA
CDA balance: $499,500
Tax on capital dividend: $0
Net to shareholder: $499,500
Stream 2: Taxable eligible dividend
Remaining cash: $1,105,403 − $499,500 = $605,903
Gross-up (38%): $605,903 × 1.38 = $836,146
Federal tax on grossed-up dividend: ~$220,800
Federal dividend tax credit (15.02% of grossed-up): −$125,589
Net federal tax: ~$95,211
Ontario tax on grossed-up dividend: ~$85,400
Ontario dividend tax credit (10% of grossed-up): −$83,615
Net Ontario tax: ~$1,785
Ontario surtax on total provincial tax: ~$4,200
Total personal tax on dividend: ~$101,196
Net from dividend stream: $605,903 − $101,196 = ~$504,707
Step 3: Total After-Tax Proceeds on Asset Deal
Capital dividend (tax-free): $499,500
Net from taxable dividend: $504,707
Total after-tax to shareholder: ~$1,004,207
Total tax paid (corporate + personal): ~$495,793
Effective rate on $1.5M gain: ~33.1%
Share Deal vs. Asset Deal: Side-by-Side Comparison
| Item | Share Deal | Asset Deal |
|---|---|---|
| Capital gain | $1,500,000 | $1,500,000 |
| LCGE applied | $1,016,836 | $0 |
| Corporate-level tax | $0 | ~$394,597 |
| Personal tax | ~$101,150 | ~$101,196 |
| Total tax | ~$101,150 | ~$495,793 |
| After-tax proceeds | ~$1,398,850 | ~$1,004,207 |
| Effective tax rate | ~6.7% | ~33.1% |
Assumes no other income in the year, full LCGE available, and 2025 federal/Ontario rates. RDTOH refund applied on asset deal. Actual results vary based on income, credits, and specific deal structure.
The share deal delivers approximately $394,000 more in after-tax cash. That gap is almost entirely attributable to the LCGE eliminating tax on $1.016M of the gain.

The 2025 LCGE: $1,016,836 and Rising
The lifetime capital gains exemption is indexed to inflation each year. Here is the recent trajectory:
| Year | LCGE Limit |
|---|---|
| 2020 | $883,384 |
| 2021 | $892,218 |
| 2022 | $913,630 |
| 2023 | $971,190 |
| 2024 | $1,016,836 |
| 2025 | $1,016,836 |
The 2025 limit may be further adjusted once the CRA confirms the inflation factor. The $1,016,836 figure reflects the most recent indexed amount.
The LCGE is a lifetime cumulative limit. Any portion used on a previous sale of QSBC shares, qualified farm property, or qualified fishing property reduces the amount available for subsequent dispositions. You cannot “reset” it.
Qualifying for the LCGE: The Three Tests
The LCGE is only available on shares that meet three simultaneous conditions under section 110.6 of the Income Tax Act:
- 90% active business asset test (at time of sale): At the moment the shares are sold, at least 90% of the corporation's assets by fair market value must be used principally in an active business carried on primarily in Canada, or consist of shares/debt of connected corporations that themselves meet this test.
- 24-month holding period test: The shares must have been owned by the individual (or a related person) continuously for at least 24 months before the sale.
- 50% active business asset test (24-month lookback): Throughout the 24 months preceding the sale, more than 50% of the corporation's assets must have been used in an active business carried on primarily in Canada.
The most common disqualifier is excess passive investments. If the corporation has accumulated a large investment portfolio, rental properties, or significant idle cash, the 90% test can fail. Many business owners purify their corporation in the years leading up to a sale — paying out excess cash as dividends, transferring passive investments to a holding company, or subscribing for additional shares to dilute passive asset value.
The Connected-Corporation Trap
If the selling corporation owns shares in other corporations, those subsidiaries must also meet the active business asset tests for their assets to count as “active” at the parent level. A common structure — operating company (OpCo) owned by a holding company (HoldCo) — can cause problems if HoldCo has accumulated passive investments that dilute its active asset ratio below 90%.
The connected-corporation rules in section 186 of the Income Tax Act define when two corporations are connected. If the selling corporation owns 10% or more of the votes and 10% or more of the fair market value of another corporation, they are connected, and the subsidiary's assets must be tested on a look-through basis. Pre-sale planning typically involves isolating passive assets in a non-connected entity. For more on how corporate income flows between Ontario entities, see our professional corporation salary vs. dividend calculator.
Extracting Proceeds After the Share Deal: The CDA Advantage
On the share deal, the seller receives cash directly — the corporation is not involved in the proceeds flow. But the residual gain above the LCGE creates an interesting secondary benefit: the capital dividend account.
Wait — on a share sale, the gain is personal, not corporate. The CDA in this scenario only applies if the corporation had previously realized capital gains that created a CDA balance, or if the deal is structured as a hybrid where some proceeds flow through the corporation. In a pure share deal where the individual sells all shares to the buyer, the after-tax proceeds of ~$1,398,850 land directly in the seller's hands. No corporate extraction needed.
This is another advantage of the share deal: there is no second layer of extraction tax. The gain is realized personally, the LCGE is applied personally, and the net cash is received personally.
What the Buyer Gives Up in a Share Deal
Buyers often resist share deals because they inherit all corporate liabilities (known and unknown), lose the ability to step up the cost base of depreciable assets, and cannot selectively exclude unwanted assets or liabilities. The $394,000 tax difference usually results in a negotiated purchase price adjustment — the seller accepts a modestly lower headline price in exchange for the share deal structure, or the buyer demands an indemnity for undisclosed liabilities.
In practice, the negotiation often splits the tax savings. A seller willing to accept a $100,000–$150,000 price reduction to keep the share deal structure still comes out $240,000–$290,000 ahead compared to a full asset deal.
Marginal Tax on the $484K Excess: Ontario's Top Rates
The $483,164 residual gain (above the LCGE) produces $280,520 of taxable income. Here is how Ontario's marginal rates stack against this income:
| Income Bracket | Combined Rate | On Capital Gains (50%) |
|---|---|---|
| $0 – $51,446 | 20.05% | 10.03% |
| $51,447 – $102,894 | 29.65% | 14.83% |
| $102,895 – $150,000 | 31.48% | 15.74% |
| $150,001 – $220,000 | 33.89% | 16.95% |
| $220,001+ (top bracket) | 53.53% | 26.77% / 35.69% |
The top-bracket capital gains rate is 26.77% on gains at 50% inclusion (first $250K) and 35.69% on gains at 66.7% inclusion (above $250K). Ontario surtax pushes effective provincial rates higher than the statutory bracket rates shown.
The portion of the residual gain above $250,000 faces the 66.7% inclusion rate at the top combined marginal rate — producing an effective capital gains rate of approximately 35.7%. This is why the LCGE is so valuable: every dollar sheltered avoids a rate that approaches 36% on the margin. For a broader look at Ontario income tax brackets, see our Ontario income tax take-home calculator.
Doubling the LCGE with Spousal Share Ownership
If both spouses own qualifying shares, each can claim up to $1,016,836 in LCGE — sheltering up to $2,033,672 of gain on a $1.5M sale. This would eliminate all personal tax on the share deal entirely.
However, the attribution rules under sections 74.1 and 74.2 of the Income Tax Act are aggressively enforced. Simply gifting or transferring shares to a spouse shortly before a sale will result in the gain being attributed back to the transferor. The shares must be genuinely owned by the spouse, typically through:
- A share subscription where the spouse pays fair market value for their shares from their own funds
- An estate freeze where the spouse subscribes for growth shares at nominal value, and all future appreciation accrues to the spouse's shares
- Section 86 share exchange or section 85 rollover structures implemented years before the sale
Planning ahead by 24+ months is critical. The 24-month holding period test applies to each shareholder individually.
