For most owner-managers, the sale of the business is the single largest taxable event of their lives. The Lifetime Capital Gains Exemption (LCGE) under section 110.6 of the Income Tax Act is the most valuable shelter available against that gain — but it is also one of the easiest to forfeit on a technicality discovered months after the deal closes. The exemption applies only to a disposition of shares (not assets), and only where those shares meet a demanding set of definitions. This article sets out the rules as they stand in 2026 and gives a structured pre-sale checklist so the qualification questions are answered while there is still time to fix them.

What the LCGE is, and the 2026 limit

The LCGE is a deduction against the taxable capital gain realized on the disposition of qualified small business corporation (QSBC) shares and qualified farm or fishing property. It is claimed by the individual shareholder on their personal return as a capital gains deduction (CRA line 25400), not by the corporation.

The exemption limit is cumulative over a lifetime and indexed annually. The base amount was raised to $1.25 million for dispositions on or after June 25, 2024, and indexation resumed for 2026. For 2026 dispositions of QSBC shares the limit is $1,275,000. Two points are worth stressing:

The figure is a capital gain ceiling, not a tax credit. Because the capital gains inclusion rate is 50%, a fully used 2026 exemption shelters $1,275,000 of gain, of which $637,500 would otherwise have been the taxable half.
The much-discussed 2024 proposal to raise the inclusion rate to two-thirds (66.67%) was deferred and then cancelled in March 2025. The inclusion rate in force for 2026 is 50%. Older planning memos that assume the higher rate are out of date.

The limit is per individual and per lifetime, reduced by any prior LCGE claims and by a cumulative net investment loss (CNIL) balance and certain allowable business investment losses. Confirm the remaining room before relying on the full figure.

The three QSBC tests

To be a QSBC share at the moment of sale, three distinct tests must be met. They are easy to state and surprisingly easy to fail.

1. The small-business-corporation test (point-of-sale, 90%). At the moment of disposition the company must be a small business corporation — a Canadian-controlled private corporation (CCPC) in which all or substantially all (CRA reads this as 90% or more) of the fair market value of its assets is used principally in an active business carried on primarily in Canada (or is shares/debt of connected SBCs).
2. The holding-period (ownership) test (24 months). Throughout the 24 months immediately before the sale, the shares must not have been owned by anyone other than the seller or a person or partnership related to the seller. Freshly issued shares — for example shares subscribed for cash shortly before a sale — generally fail this test.
3. The basic-asset test (50% throughout 24 months). Throughout that same 24-month period, more than 50% of the fair market value of the company's assets must have been used principally in an active business carried on primarily in Canada (or invested in connected corporations meeting their own tests).

Tests 2 and 3 look backward over a 24-month window. Test 1 looks at a single instant. The interaction of the point-in-time 90% test and the throughout 50% test is where most planning effort is spent.

The 24-month look-back trap

The most common reason a sale fails to qualify is that the corporation is holding too much passive property. Retained earnings that have accumulated as cash, marketable securities, a large shareholder loan receivable, or surplus real estate held for investment are not active-business assets. If those passive assets push the active-business proportion below 90% at the closing date, the point-of-sale test fails; if they push it below 50% at any point in the 24-month look-back, the basic-asset test fails for the whole window.

The trap is the look-back. Stripping out passive cash the week before closing fixes the 90% point-in-time test, but it cannot retroactively cure a 50% breach that existed eighteen months earlier. This is why "purification" needs to begin well before a sale is contemplated. Common purification steps include:

Paying a dividend or return of capital to move surplus cash out of the operating company (often up to a connected holding company on a tax-deferred inter-corporate basis under s.112).
Repaying shareholder loans and clearing intercompany balances that read as non-active assets.
Distributing or hiving off investment portfolios and surplus real estate before the look-back window opens.
Documenting that property genuinely used in the business (e.g., reasonable working-capital reserves) is recorded as active.

Because dividends and loan repayments carry their own tax consequences — including subsection 15(2) shareholder-benefit rules on loans and the surplus-stripping limits in s.84.1 — purification should be modelled, not improvised.

A pre-sale planning framework

The following sequence works backward from the intended closing date. Ideally it starts at least 24 months before any sale, but it remains useful at any stage.

Step 1 — Confirm corporate status. Is the company a CCPC? Loss of CCPC status (for example, a non-resident or public-company shareholder, or certain shareholder agreements) can disqualify the shares.
Step 2 — Identify the shareholders and their LCGE room. Map who actually owns shares, for how long, and how much exemption each has left after prior claims, CNIL, and ABILs.
Step 3 — Run the asset tests on the balance sheet. Calculate the active-vs-passive split today and over the trailing 24 months. Flag any month the active proportion dipped below 50%, and the current proportion against the 90% point-of-sale bar.
Step 4 — Purify if needed, then let the clock run. Move passive assets out and, where a historical breach exists, allow a clean 24-month period to accumulate before closing.
Step 5 — Consider crystallization. Where a sale is not imminent but the shares qualify now, a crystallization can lock in today's exemption (see below).
Step 6 — Consider multiplication. Where a family trust or qualifying family members hold (or could be reorganized to hold) shares, more than one exemption may be available.
Step 7 — Model the AMT. Project alternative minimum tax in the year of sale and the recovery over the following years.
Step 8 — Structure the deal as a share sale. The LCGE applies to shares, not assets. Reconciling a buyer's preference for an asset deal with the seller's need for a share deal is core to structuring a tax-efficient business sale.

Crystallization: banking the exemption early

Crystallization means triggering a notional or actual disposition of QSBC shares while they qualify, claiming the exemption, and bumping the adjusted cost base of the shares up to fair market value — without an arm's-length sale. The rationale is defensive: a company that qualifies today may not qualify on the day a buyer eventually appears (passive assets accumulate, an emergency cash injection skews the asset mix, or the rules change). Crystallizing captures the exemption against the current cost base while the tests are clearly met.

Crystallization is commonly implemented through a section 85 rollover into a holding company or a share-for-share reorganization that engineers a gain equal to the available exemption. It interacts with AMT (the gain is included for AMT purposes even though no regular tax is payable) and with s.84.1 if a holding company is introduced, so the cost-base bump must be sized deliberately. It is frequently combined with an estate freeze, which freezes the founder's value and shifts future growth to the next generation.

Multiplying the exemption with a family trust

Each individual has their own LCGE. A discretionary family trust holding the growth shares of the operating company can, on a sale, allocate the capital gain among multiple beneficiaries — for example a spouse and adult children — so that each beneficiary applies their own exemption. With three qualifying beneficiaries the sheltered gain can in principle reach roughly $3.8 million (three times $1,275,000) rather than a single $1,275,000.

Multiplication is powerful but tightly constrained:

The trust generally must satisfy the 24-month holding-period test, so the structure must be in place well before any sale.
The tax on split income (TOSI) rules can claw back the benefit for beneficiaries who are not sufficiently engaged in the business; an LCGE allocation can be vulnerable where a beneficiary's involvement is thin.
Allocating a gain to a minor child is generally ineffective for LCGE multiplication.
Each beneficiary must have remaining exemption room and a clean CNIL balance.

Done correctly the family trust is the engine of multiplication; done late or without regard to TOSI it can produce a gain with no shelter at all.

The AMT interaction — the surprise tax bill

Claiming the LCGE can produce regular tax of zero while still generating a substantial alternative minimum tax liability. Under the AMT rules that took effect in 2024, a portion of the LCGE-sheltered gain is added back to adjusted taxable income for AMT purposes — the effective inclusion is 30% of the capital gain — and AMT is then computed at a federal rate of 20.5% above a basic exemption tied to the start of the fourth federal bracket. The result: a clean LCGE claim that pays no ordinary tax can still trigger AMT in the year of sale.

AMT is not necessarily a permanent cost. It is generally recoverable as a credit against regular tax over the following seven years, to the extent regular tax exceeds the minimum in those years. But a seller who exits the business and has little subsequent income may never fully recover the AMT, turning a timing difference into a real cost. The year-of-sale cash impact and the recovery profile should both be modelled before the exemption is claimed.

Worked example

Assume an owner sells the shares of her CCPC in 2026 for a $1,500,000 capital gain. The shares are QSBC: the company is a CCPC, 95% of its assets are active at closing, and both 24-month tests are met.

Exemption applied: $1,275,000 of the gain is sheltered by her full 2026 LCGE. The remaining $225,000 is an ordinary capital gain.
Regular taxable gain: $225,000 × 50% inclusion = $112,500 added to her income and taxed at her marginal rate.
AMT add-back: 30% of the $1,275,000 sheltered gain = $382,500 enters her adjusted taxable income for AMT purposes, on top of the regular taxable portion — potentially generating minimum tax in the year of sale even though most of the gain bears no ordinary tax.

Now contrast multiplication. Suppose a family trust had held the shares for more than 24 months and the same $1,500,000 gain were allocated $750,000 each to the owner and her actively engaged adult child, both with full exemption room and clean CNIL. Each $750,000 falls entirely under the $1,275,000 limit, so the entire gain is sheltered for regular tax — though each beneficiary should still model AMT on their 30% add-back. The contrast illustrates why the trust must be established years ahead, not in the closing room.

How Barrett Tax Law approaches the LCGE

Our work on the exemption begins long before a sale. We review the corporate structure and shareholder register to confirm CCPC and QSBC status, run the active-versus-passive asset analysis across the 24-month window, and identify where purification or a clean holding period is required. Where appropriate we implement crystallizations under s.85, design family-trust structures with TOSI in mind, and model the AMT cash impact and recovery in the year of sale. We also coordinate the LCGE with the broader deal structure so the transaction is documented as a qualifying share sale. You can read more on our lifetime capital gains exemption and tax-efficient business sales pages, and our note on owner-manager compensation covers the surrounding distribution planning.

If you are contemplating a sale — or simply want to know whether your shares would qualify today — we offer a free initial consultation to review your structure and map the planning runway available to you.

Frequently asked questions

How much is the Lifetime Capital Gains Exemption in 2026?

For 2026, the LCGE limit on qualified small business corporation (QSBC) shares is $1,275,000. This reflects the base amount of $1.25 million set for dispositions on or after June 25, 2024, with annual inflation indexing resuming in 2026 at roughly a 2% adjustment. The figure is a capital-gain ceiling, not a tax credit: because the capital gains inclusion rate remains 50%, a fully used exemption shelters $1,275,000 of gain, of which $637,500 would otherwise have been the taxable half. The limit is cumulative over your lifetime and per individual, so it is reduced by any prior exemption claims and can be ground down by a cumulative net investment loss (CNIL) balance. Confirm your remaining room before relying on the full amount, and confirm the current-year figure, which changes each year with indexation.

Did the capital gains inclusion rate increase to two-thirds?

No. The 2024 federal budget proposed raising the capital gains inclusion rate from one-half to two-thirds (66.67%) on gains above a threshold, but the measure was never enacted. The government first deferred the proposed effective date and then, in March 2025, cancelled it entirely. As a result, the inclusion rate in force for 2026 is 50% for individuals, trusts, and corporations alike. This matters for LCGE planning because some older memos and calculators still assume the higher rate. Under the 50% rate, only half of a non-sheltered capital gain is taxable. The cancellation did, however, preserve the increase in the LCGE limit to $1.25 million (now indexed), so the larger exemption survived even though the inclusion-rate hike did not.

What is the 24-month look-back trap for QSBC shares?

Two of the three QSBC tests look backward over the 24 months before a sale. The holding-period test requires the shares to have been owned only by you or related persons throughout that window, and the basic-asset test requires that more than 50% of the company's asset value was used in an active Canadian business throughout the same period. The trap is that you cannot retroactively fix a historical breach. If the company held too much passive property (surplus cash, marketable securities, investment real estate, large shareholder loans) eighteen months before closing, dropping the active proportion below 50%, stripping that property out the week before the sale will not cure it. This is why purification — moving passive assets out, often to a connected holding company — must begin well before a sale is contemplated, so a clean 24-month period can accumulate.

Can a family trust multiply the capital gains exemption?

Yes, in the right structure. Because each individual has their own LCGE, a discretionary family trust holding the company's growth shares can allocate a capital gain on a sale among several beneficiaries so that each applies their own exemption. With three qualifying beneficiaries the sheltered gain can approach three times the annual limit. The constraints are significant: the trust generally must satisfy the 24-month holding-period test, so it must be in place years before a sale; the tax on split income (TOSI) rules can claw back the benefit for beneficiaries who are not genuinely engaged in the business; an allocation to a minor child is generally ineffective; and each beneficiary needs remaining exemption room and a clean CNIL balance. Implemented early and with TOSI in mind, multiplication is powerful. Set up late, it can leave a gain with no shelter.

Why do I owe alternative minimum tax (AMT) if the LCGE covers my gain?

Because the LCGE that eliminates your regular tax does not eliminate your gain for AMT purposes. Under the AMT rules in effect since 2024, an effective 30% of an LCGE-sheltered capital gain is added back to your adjusted taxable income for the minimum-tax calculation, which is then assessed at a 20.5% federal rate above a basic exemption tied to the fourth federal tax bracket. A clean LCGE claim that produces zero ordinary tax can therefore still trigger a substantial AMT bill in the year of sale. AMT is generally recoverable as a credit against regular tax over the following seven years, to the extent your regular tax exceeds the minimum in those years. But a seller who exits the business with little later income may never fully recover it, so both the year-of-sale cash cost and the recovery profile should be modelled in advance.

What is crystallization and when does it make sense?

Crystallization means triggering a disposition of QSBC shares while they currently qualify, claiming the exemption, and stepping up the adjusted cost base of the shares to fair market value — without an arm's-length sale. The point is defensive: a company that qualifies today may not qualify when a buyer eventually appears, because passive assets accumulate, an emergency cash injection skews the asset mix, or the rules change. Crystallizing locks in the exemption against today's value while the tests are clearly satisfied. It is usually implemented through a section 85 rollover into a holding company or a share-for-share reorganization that engineers a gain equal to the available exemption, and it is often combined with an estate freeze. Because it interacts with AMT and the surplus-stripping rules in section 84.1 when a holding company is introduced, the size of the cost-base bump should be set deliberately rather than maximized blindly.
