Lifetime Capital Gains Exemption on QSBC Shares 2026: The Exact $1.25M Number on a Business Sale

The 2026 LCGE Number: $1,250,000 on QSBC Shares

The Lifetime Capital Gains Exemption for Qualified Small Business Corporation shares in 2026 is $1,250,000. This is the maximum capital gain — not taxable capital gain, not proceeds — that you can shelter from tax over your entire lifetime when selling QSBC shares.

The number moved significantly. From 1988 to 2023, the LCGE climbed gradually from $500,000 to $971,190 through annual CPI indexation. The 2024 federal budget jumped it directly to $1,250,000 — a 29% increase — effective June 25, 2024. Starting in 2026, the $1,250,000 base is indexed annually to inflation again, so expect it to creep up by $10,000–$20,000 per year.

Two distinctions that trip people up:

• The $1,250,000 is a gain limit, not a proceeds limit. If you sell for $2M with a $750,000 adjusted cost base, your gain is $1,250,000 and it is fully sheltered. If you sell for $2M with a $1 ACB, your gain is ~$2M and only $1,250,000 of it is sheltered.
• The LCGE is per person, per lifetime. If you claimed $200,000 of LCGE on a previous business sale in 2019, you have $1,050,000 remaining in 2026 (the 2024 budget increase topped up everyone's remaining room). Track your cumulative claims on CRA Form T657.

LCGE vs the farm/fishing exemption

The $1,250,000 applies to QSBC shares and qualified farm or fishing property — they share the same lifetime cap. But the 2024 budget also introduced the Canadian Entrepreneurs' Incentive (CEI), which adds an additional $250,000 of relief (phasing in at $400,000 per year over 10 years) for certain eligible property. The CEI is a separate deduction that stacks on top of the LCGE for qualifying dispositions. For most business-sale scenarios in 2026, the headline number remains $1,250,000.

The Three QSBC Tests Your Shares Must Pass

A share does not automatically qualify for the LCGE just because it is in a Canadian-controlled private corporation (CCPC). Three tests under sections 110.6 and 248(1) of the Income Tax Act must all be satisfied. Fail one, and the entire exemption is lost on that disposition.

Test 1: The SBC test at the moment of sale (90% rule)

At the exact moment you sell the shares, 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. "Active business" means the real operations — not passive investment portfolios, not term deposits sitting in the corporate account, not rental properties held for income.

This is the test that catches the most business owners. A corporation that runs a profitable consulting practice worth $1.5M but has also accumulated $400,000 of retained earnings sitting in a GIC? That GIC is a passive asset. Total assets: $1.9M. Active-business share: $1.5M / $1.9M = 79%. Below 90%. LCGE denied.

Test 2: The 24-month holding-period test

You (or a person related to you) must have owned the shares for at least 24 months before the disposition. Shares purchased last year do not qualify, regardless of how pristine the corporation's asset mix is.

The 24-month clock starts when the shares are acquired — through incorporation, purchase, or a section 85 rollover. If a share reorganization occurs (common in estate freezes or purification), the clock may restart on the new shares. This is the mistake that undoes last-minute planning: restructuring shares 12 months before a sale means the new shares have not been held for 24 months, even if you have owned the underlying business for decades.

Test 3: The 50% active-asset test throughout the 24-month hold

Throughout the entire 24-month period before the sale, more than 50% of the corporation's assets by fair market value must have been used in an active business in Canada. This is a lower bar than the 90% point-in-time test, but it covers the full two-year window.

In practice, if you can pass the 90% test at sale date, the 50% test over the prior 24 months is usually satisfied automatically. The risk case: you purified the corporation last month (passing the 90% test today), but for the first 20 of the last 24 months, the corporation was 45% passive. That fails the 50% look-back.

Purification: Stripping Passive Assets to Pass the 90% Test

Most profitable CCPCs accumulate passive assets over time. Retained earnings get parked in GICs, corporate investment accounts, or term deposits. That is prudent cash management — until you try to sell the business and the LCGE blows up because you are at 85% active assets instead of 90%.

Purification is the process of removing passive assets from the corporation before the sale so the 90% test is met. The earlier you do it, the better — because you also need to satisfy the 50% test over the prior 24 months.

Common purification strategies

The AMT Trap: Why Your $0 Capital Gains Tax Bill May Not Be $0

Here is the part most LCGE articles skip. Claiming a large Lifetime Capital Gains Exemption deduction can trigger Alternative Minimum Tax (AMT) in the year of sale. The AMT is a parallel tax calculation designed to ensure that taxpayers who claim large deductions or exemptions still pay a minimum amount of tax.

How AMT interacts with the LCGE (2026 rules)

When you claim the LCGE capital gains deduction on your T1 return, the AMT calculation adds back a portion of the deducted gain. Specifically, 30% of the capital gains sheltered by the LCGE are excluded from AMT adjusted taxable income (you get credit for 30%), but 70% is added back. The AMT then applies a flat 20.5% rate on your adjusted taxable income above the $173,205 AMT basic exemption.

If the AMT calculated exceeds your regular federal tax for the year, you pay the higher amount — the AMT. The excess AMT paid (AMT minus regular tax) becomes a carry-forward credit that you can apply against regular tax payable over the following seven years. It is not lost — it is a timing cost, not a permanent cost.

The AMT does not reduce the value of the LCGE — it delays part of the tax benefit. But it creates a real cash-flow requirement in the year of sale. If you are counting on receiving $1.25M tax-free and immediately deploying all of it, the ~$169,500 AMT bill changes your planning. Budget for it.

Multiplying the LCGE: Family Trusts and Share Freezes

The LCGE is per individual. Every Canadian resident gets their own $1,250,000 lifetime exemption. This creates a powerful planning lever: if you can allocate capital gains across multiple family members — each with their own unused LCGE — you multiply the total shelter.

Strategy 1: Family trust holding QSBC shares

A discretionary family trust holds common shares of the operating corporation. The trust's beneficiaries include the business owner, their spouse, and their adult children. When the shares are sold, the trust realizes the capital gain and allocates it among the beneficiaries. Each beneficiary then claims their own LCGE against their allocated share of the gain.

With four beneficiaries (two parents, two adult children), the family can shelter up to $5,000,000 of capital gains — four times the individual limit.

The tax savings from multiplying the LCGE across a family of four — versus using a single exemption — is over $1,000,000. This is not an aggressive interpretation; it is the explicit purpose of the exemption being per-individual under section 110.6.

Strategy 2: Estate freeze + growth shares for the next generation

An estate freeze locks the current owner's share value at today's fair market value and issues new growth shares (often to a family trust or directly to children). All future appreciation accrues on the new shares. When the business is eventually sold, the owner's frozen shares and the children's growth shares are each eligible for the LCGE — multiplying the exemption.

The estate freeze is also the standard tool for managing the deemed-disposition tax at death. If you are an incorporated business owner over 60 and have not evaluated a freeze, you are likely leaving six figures of tax savings on the table — both on a future sale and on the terminal return.

TOSI and the kiddie-tax guardrail

The Tax on Split Income (TOSI) rules under section 120.4 can apply if capital gains are allocated to family members (including adult children) who do not meaningfully contribute to the business. Post-2018 TOSI rules are broad: the "excluded business" exception requires the family member to have been actively engaged in the business on a regular, continuous, and substantial basis in the year of the disposition or in five prior years. If TOSI applies, the gain allocated to that person is taxed at the top marginal rate and the LCGE does not help.

This is the guardrail that prevents a business owner from simply papering over share ownership to children who have no involvement. A corporate tax advisor who works with share reorganizations and trusts is essential here — the rules are technical, and the cost of getting it wrong is losing the LCGE entirely on the allocated gains.

Cumulative Net Investment Loss (CNIL): The Hidden LCGE Reducer

Your available LCGE is reduced dollar-for-dollar by your Cumulative Net Investment Loss (CNIL) balance. CNIL accumulates whenever your investment expenses (interest on money borrowed to invest, rental losses, partnership losses from investments) exceed your investment income (interest income, property income, taxable capital gains not sheltered by the LCGE) over your lifetime since 1988.

If you have been deducting interest on an investment loan for years and reporting small investment income, you may have a CNIL balance of $50,000 or more — reducing your available LCGE from $1,250,000 to $1,200,000 without realizing it. Check your CNIL balance on your prior T1 returns or ask your accountant for a CNIL calculation before relying on the full exemption.

Full Worked Example: $1.25M QSBC Share Sale in Ontario

A Mississauga bookkeeper, age 58, sells 100% of the shares of her incorporated bookkeeping practice for $1,250,000. She incorporated the business 12 years ago at a nominal cost ($1 ACB). She has held the shares personally the entire time. She has never previously claimed the LCGE. Her CNIL balance is $0. The corporation passed all three QSBC tests — she purified excess cash 24 months before the sale by paying herself a dividend.

The LCGE saves $334,500 in permanent tax. The ~$169,500 AMT is a cash-flow cost in year one — it comes back as a credit over the next seven years against regular tax. If she has RRSP or RRIF withdrawals, employment income, or investment income in those years, the credit offsets her regular tax dollar for dollar.

Without the LCGE — because she failed the 90% test, or because she had not held the shares for 24 months — she would owe $334,500 of permanent, non-recoverable tax. That is the difference between walking away with $1.25M and walking away with $915,500.

Pre-Sale Checklist: 11 Things to Verify Before Claiming the LCGE

1. Confirm CCPC status. The corporation must be a Canadian-controlled private corporation. If a non-resident or public company holds any shares, verify control status.
2. Run the 90% active-asset test. Get a fair-market-value appraisal of all corporate assets. Identify every passive asset: GICs, investment accounts, excess cash, life insurance CSV, rental property.
3. Check the 50% asset test over the past 24 months. Review financial statements for each of the prior 24 months. Flag any month where passive assets exceeded 50% of total FMV.
4. Confirm 24-month holding period. When did you acquire these specific shares? If there was a reorganization, freeze, or rollover, when did the clock restart?
5. Calculate your CNIL balance. Review T1 returns since 1988 for cumulative investment losses vs. investment income. A positive CNIL reduces available LCGE dollar-for-dollar.
6. Check for prior LCGE claims. Any previous capital gains deduction on QSBC shares or farm/fishing property reduces your remaining room. Total lifetime claims are tracked on CRA Form T657.
7. Purify if needed. Remove passive assets via dividend, loan repayment, or holdco transfer — but only if you have 24 months before the anticipated sale.
8. Model the AMT. Calculate the AMT payable in the year of sale and ensure you have the cash flow to cover it.
9. Evaluate LCGE multiplication. If the gain exceeds $1,250,000, explore whether a family trust or share reorganization (set up 24+ months in advance) can allocate gains across family members.
10. Review TOSI exposure. If gains will be allocated to family members, confirm each person meets the "excluded business" test under s. 120.4.
11. File Form T657. The capital gains deduction is claimed on your T1 return using CRA Form T657 — Capital Gains Deduction. It is not automatic; you must elect it.

Alberta vs Ontario: How Province of Residence Changes the Math

The LCGE is a federal deduction — it works the same in every province. But the tax savings depend on your province's marginal rates, and the AMT recovery depends on your province's tax payable in subsequent years.

The LCGE is worth $34,500 more in Ontario than Alberta purely because Ontario's top combined rate is 5.53 percentage points higher. Province of residence is one of the largest levers in business-sale tax outcomes — and probate fees amplify the gap on the estate side.
