The $1.275 million exemption
is earned in advance
Most Ontario business owners assume they will claim the lifetime capital gains exemption when they eventually sell. Many discover too late that surplus cash, investments or non-operating real estate quietly destroyed their eligibility years earlier. This guide explains the three-part qualified small business corporation share test, why purification is so often required, the practical timeline, and the traps that catch owners who wait until a letter of intent is already signed.
By Jonathan Kleiman, Barrister & Solicitor · Published August 2026
In 2026, the lifetime capital gains exemption (LCGE) shelters up to $1,275,000 of capital gains on the sale of qualified small business corporation shares. Where both spouses or common-law partners genuinely and independently own qualifying shares, the combined room can exceed $2.5 million. For the owner of a successful Ontario company, that is very often the single largest tax benefit they will ever be entitled to claim.
Entitled to claim, that is, if the shares qualify. The exemption is not automatic. It depends on a technical three-part test that looks backward over the 24 months before the sale, and a profitable corporation drifts offside that test easily: retained earnings pile up as cash and GICs, the company buys a rental property, an investment account grows quietly in the background. None of it feels like a tax decision at the time. All of it counts against eligibility on the day you sell.
This article is general information, not legal or tax advice. The rules in section 110.6 of the Income Tax Act are complex and fact-specific, and the figures are indexed and change over time. Before acting on anything here, get advice from a qualified tax advisor and corporate counsel on your own numbers and structure, ideally years before a sale.
What is the lifetime capital gains exemption?
The LCGE is a cumulative lifetime tax exemption in section 110.6 of the federal Income Tax Act that lets an individual shelter capital gains on the disposition of qualified small business corporation shares (QSBCS), up to $1,275,000 for 2026. The 2024 federal budget raised the base amount to $1,250,000 for dispositions on or after June 25, 2024, and indexation resumed in 2026, which produces the current figure. Because only half of a capital gain is taxable, the exemption corresponds to a capital gains deduction of up to $637,500 of taxable capital gains, claimed on the seller's personal return as the capital gains deduction.
Three boundaries define the exemption before any test is applied:
- Individuals only. Corporations and trusts cannot claim the LCGE. A trust can allocate gains to individual beneficiaries who claim their own exemption, discussed below, but the claim itself is always personal.
- Share sales only. The exemption applies to a disposition of qualifying shares. If the corporation sells its assets, the gain lands inside the corporation and the LCGE is simply not available on it.
- Lifetime and cumulative. Room used on an earlier disposition, including under the lower historical limits, reduces what remains today.
Two housekeeping points to avoid confusion. First, do not mix the LCGE up with the separate "eligible small business corporation share" rollover in section 44.1 of the Act, which is a deferral mechanism for reinvested proceeds with its own distinct test, not an exemption. Second, the capital-gains landscape moved around in 2024 and 2025: the proposed increase to the capital gains inclusion rate was cancelled in March 2025, and the proposed Canadian Entrepreneurs' Incentive was abandoned in the 2025 federal budget. The increased and indexed LCGE survived both reversals. For 2026 it is the centrepiece of sale planning for private-company owners.
Why does the LCGE only matter in a share sale?
Because the exemption applies solely to a disposition of shares by an individual, a seller who agrees to an asset deal gives up the LCGE on that transaction entirely. That single rule drives more deal-structure negotiation than any other tax provision I see in private company sales. The seller wants to sell shares to capture the exemption and walk away clean. The buyer usually wants to buy assets, taking only the liabilities it agrees to and stepping up the cost base of what it acquires.
In practice the parties negotiate around that tension: a share deal at a somewhat lower headline price, an asset deal with a price gross-up that compensates the seller for the lost exemption, or a hybrid with indemnities and holdbacks that make a share purchase tolerable for the buyer. The tax cost of losing the LCGE is large enough that it often becomes the central commercial issue. My guide to asset purchase vs. share purchase in Ontario works through that trade-off, including the liability and employee differences that sit alongside the tax.
The consequence for planning is blunt: qualifying your shares is necessary but not sufficient. You also have to win the structure negotiation, and you negotiate from a much stronger position when the qualification work is already done and documented before the letter of intent is signed.
What is the three-part QSBCS test?
To be qualified small business corporation shares under subsection 110.6(1), the shares must pass three tests: the corporation must be a small business corporation at the time of sale, the shares must generally have been held only by the seller or related persons for the preceding 24 months, and the corporation must have kept a majority-active balance sheet throughout those 24 months. All three must be satisfied. Failing any one of them, even technically, puts the exemption out of reach for that disposition.
1. Small business corporation at the time of sale
At the determination time, usually closing, the corporation must be a Canadian-controlled private corporation (CCPC), and all or substantially all of the fair market value of its assets must be attributable to assets used principally in an active business carried on primarily in Canada, or to shares or debt of connected corporations that themselves meet the test. The CRA's long-standing administrative position reads "all or substantially all" as 90% or more by fair market value. A corporation that is 85% active on closing day fails, no matter how operational the business looks from the outside.
2. The 24-month holding period
Throughout the 24 months immediately before the disposition, the shares must not have been owned by anyone other than the seller or a person or partnership related to the seller. An anti-avoidance rule in paragraph 110.6(14)(f) deems newly issued shares to have been owned by an unrelated person immediately before issuance, so freshly issued shares generally fail the 24-month test unless they fall within narrow exceptions, such as shares issued in exchange for other shares or as consideration for the transfer of substantially all of the assets of an active business.
There is a limited relieving rule on death: where shares would fail only because of the deemed disposition that occurs when a shareholder dies, they may still qualify if the corporation met the test at some point in the 12 months before death. It is narrow, and it is no substitute for planning while the owner is alive.
3. The 50% active-asset test across the 24 months
Throughout the 24 months before the sale, more than 50% of the fair market value of the corporation's assets must have been attributable to active business assets used primarily in Canada, or to qualifying shares or debt of connected corporations. So the balance sheet does not only have to be clean on closing day. It has to have been at least majority-active for the entire two-year window, which is precisely why a last-minute cleanup cannot fix a corporation that spent the past two years holding a large investment portfolio.
Which assets put your eligibility at risk?
Passive assets count against both the 90% closing-day test and the 50% two-year test, and the usual culprits are surplus cash, portfolio investments, non-operating real estate, insurance cash values and loans to shareholders. None of these are exotic. They are what a profitable, conservatively run company accumulates by default:
- cash and short-term deposits beyond what the business reasonably needs as working capital;
- marketable securities, GICs and investment portfolios held inside the operating company;
- real estate that is not used principally in the active business, including rental property;
- the cash surrender value of corporately owned life insurance; and
- loans receivable from shareholders or related parties.
Two refinements matter. First, working capital genuinely required by the business is an active asset; the question is always how much cash the operations actually need, which is a factual judgment your accountant should be able to defend. Second, a "specified investment business", generally a business whose principal purpose is earning income from property and which does not employ more than five full-time employees, is not an active business for these purposes. Holding the investments inside a division and calling it a business does not fix the problem.
The pattern I see most often is not an owner who made a bad decision. It is an owner who made no decision: fifteen profitable years, dividends never quite caught up with earnings, and by the time a buyer appears the company is sitting on seven figures of cash and securities. The business is excellent. The shares are not qualified.
Thinking about selling in the next few years?
The LCGE window opens 24 months out. Get the structure reviewed before the clock matters.
What is purification, and how is it done?
Purification means deliberately removing passive assets from the corporation so that its shares meet the 90% and 50% thresholds, and it is usually done through some combination of distributions and a tax-deferred transfer of investments to a holding company. The right mix depends on the balance sheet, the shareholders' tax positions and the time available. The main tools:
Distributions
The simplest purification is paying the surplus out: taxable dividends, capital dividends where a capital dividend account balance exists, repayment of shareholder loans, or bonuses where they make sense. Distributions shrink the passive side of the balance sheet directly, but they can carry their own immediate tax cost, which has to be weighed against the exemption being protected.
Section 85 rollover to a holding company
Where the owner wants to keep the investments rather than spend them, passive assets can be moved to a separate holding company on a tax-deferred basis under section 85 of the Income Tax Act. The parties jointly elect a transfer amount within the permitted range and file Form T2057. Done properly, the operating company is left holding the active business while the investment portfolio compounds inside the holdco, out of the QSBC calculation. Any rollover plan that moves shares to a related corporation should also be checked against section 84.1, discussed below, so a step taken to protect the exemption does not create a deemed-dividend problem on the eventual sale. The structure has other uses too, from creditor protection to timing personal income; my guide on whether you need a holding company in Ontario covers the broader picture.
Incorporating an unincorporated business
If the business currently operates as a sole proprietorship or partnership, there are no shares to sell and no LCGE to claim. A section 85 rollover of the business into a new corporation can start the QSBC clock, but the incorporation itself generally needs to happen at least 24 months before the target sale date for the holding-period test to be met. If a sale is even a distant possibility, that timing consideration belongs in the sole proprietorship vs. incorporation decision.
Timing is the whole game
Because the 50% test runs continuously through the 24 months before closing, purification generally has to be substantially complete 18 to 24 months before the anticipated sale, and the balance sheet has to be kept clean from then on. Waiting until a buyer is at the table is usually too late for a clean result. In the final two years before a planned exit, I suggest owners have their accountant monitor the active-asset ratio quarterly, treating 90% as the target even mid-window, so ordinary cash accumulation never quietly re-poisons the test.
What is the section 84.1 trap in non-arm's-length sales?
Section 84.1 is an anti-surplus-stripping rule that can convert what looks like an exempt capital gain into a taxable dividend when an individual sells shares to a corporation they do not deal with at arm's length. The classic fact pattern is a sale to a company controlled by family: the owner sells shares to a purchaser corporation set up by a child or sibling, takes back cash or a promissory note, and expects a capital gain sheltered by the LCGE. Where section 84.1 applies, it can grind the paid-up capital of any share consideration and deem the non-share consideration to be a dividend, which is taxed as a dividend and gets no exemption at all.
This is why "just sell the company to the kids' holdco" is never a plan on its own. Any sale where the buyer is related to you, or is a corporation connected to people related to you, needs section 84.1 analysis before the structure is chosen.
The intergenerational transfer carve-out
Parliament created a limited exception for genuine intergenerational business transfers, first in the 2021 private member's Bill C-208 and then substantially reshaped for dispositions on or after January 1, 2024. In broad strokes, a parent can sell QSBC shares (or family farm or fishing shares) to a corporation controlled by one or more adult children or grandchildren without triggering the deemed dividend, provided a series of conditions about transferring control, management and economic interest are met over defined periods. The rules offer two routes, an immediate transfer and a gradual transfer, with different tests and timelines, and the details are well beyond a blog post. What matters here is that the carve-out exists, it is conditional and time-bound, and family succession deals should be designed around it deliberately rather than discovered in an audit.
Can a family trust multiply the exemption?
Yes: a discretionary family trust holding QSBC shares can allocate capital gains to multiple individual beneficiaries, and each beneficiary who is a natural person may apply their own LCGE room to the allocated gain, multiplying the exemption across the family. On a large enough sale, a properly built trust structure can shelter several multiples of the individual limit. It is one of the strongest reasons owners of growing companies put a family trust into the share structure years before any sale.
The strategy has real limits, and they are where the planning lives:
- Only individuals claim. The trust itself has no exemption; it can only flow qualifying gains out to beneficiaries who claim personally.
- Attribution rules. Gains on property transferred between spouses can be attributed back under subsection 74.2(1), and subsection 75(2) can attribute trust income and gains to a settlor who retains control or a reversionary interest. A trust settled or funded carelessly can collapse the whole plan.
- CRA scrutiny of allocations. CRA has taken restrictive positions on how freely trustees can pick which beneficiaries receive the LCGE-eligible portion of a gain. Allocation mechanics need to be respected, not improvised at filing time.
- Minor beneficiaries. For a minor, the amount generally must actually be paid or made legally payable to the child in the year. "On paper only" allocations invite reassessment.
- The 21-year rule. A trust is deemed to dispose of its property every 21 years, which puts a hard horizon on structures that were meant to be left alone indefinitely.
The tax-on-split-income rules are the other spectre families worry about, but gains that qualify for the LCGE are generally excluded from TOSI, which is one more reason the QSBC status of the shares is worth protecting. Trust multiplication is genuinely powerful and genuinely technical: it needs corporate counsel and tax advisors working from the same drawing.
Does claiming the LCGE trigger alternative minimum tax?
It can: under the AMT regime in place since 2024, a portion of the capital gain sheltered by the exemption (currently 30%) is added back into the minimum-tax calculation, so a large exempt gain can still generate a tax bill in the year of sale. AMT paid is generally recoverable as a credit against regular tax over the following seven years, so for many sellers it is a timing cost rather than a permanent one. But a seller who has retired on the sale proceeds may not have enough regular tax in the recovery window to get it all back. The AMT number belongs in the closing model, alongside the exemption itself, before anyone signs.
What is the practical timeline before a sale?
Work backward from the target closing date: the structural moves need to be finished 18 to 24 months out, which means the review has to happen even earlier. Here is the sequence I encourage owners to follow. It also happens to be the same runway that maximizes price, because a company with a clean balance sheet and clean records diligences well; my guide on planning your business exit covers that broader preparation.
- 24+ moReview and restructure
Have your accountant test the active-asset ratio today. Begin purification if needed, put a holdco or family trust in place if the numbers justify it, and incorporate if the business is still unincorporated.
- 18–24 moComplete major purification
Substantially finish the big moves: section 85 transfers, surplus distributions, real-estate separation. Confirm the 24-month holding period is running cleanly for every intended claimant.
- 12 moMaintain and document
Monitor the ratio quarterly, keep surplus swept, update the valuation, and clean up the minute book and corporate records a buyer will diligence.
- 6 moConfirm QSBC status
Get a point-in-time confirmation from your accountant that the shares qualify, fix any residual passive assets, and prepare the data room.
- LOIHold the structure
Negotiate the letter of intent knowing what the exemption is worth to you. If the buyer insists on assets, price the gross-up; do not give the structure away for free.
Starting early is the single highest-leverage decision most owners can make. Every technique in this article works better, and some only work at all, with a two-year runway.
Frequently asked questions
How much is the lifetime capital gains exemption in 2026?
For 2026 the lifetime capital gains exemption shelters up to $1,275,000 of capital gains on the disposition of qualified small business corporation shares. The 2024 federal budget raised the base amount to $1,250,000 for dispositions on or after June 25, 2024, and indexation resumed in 2026. Because only half of a capital gain is taxable, the exemption corresponds to a capital gains deduction of up to $637,500 of taxable capital gains. It is a cumulative lifetime limit, so any amount claimed in earlier years reduces what remains.
Does the LCGE apply to an asset sale?
No. The exemption applies only to the disposition of qualifying shares. If the corporation sells its assets, the gain is realized inside the corporation and no lifetime capital gains exemption is available on that gain. That single rule is why sellers almost always push for a share deal and why the structure question should be settled before a letter of intent is signed.
What are qualified small business corporation shares?
Qualified small business corporation shares, or QSBCS, are shares that meet a three-part test in subsection 110.6(1) of the Income Tax Act. At the time of sale the corporation must be a Canadian-controlled private corporation with all or substantially all of its assets, which the CRA generally interprets as 90% or more by fair market value, used principally in an active business carried on primarily in Canada. The shares must generally have been owned only by the seller or a related person or partnership throughout the 24 months before the sale. And throughout that 24-month period, more than 50% of the corporation's asset value must have been attributable to active business assets or to shares or debt of connected corporations that themselves qualify.
What does "purification" mean for the LCGE?
Purification means removing passive assets, such as surplus cash, marketable securities, investment real estate and other non-operating assets, from the corporation so that its shares meet the active-asset thresholds in the QSBC test. Common techniques include paying dividends, repaying shareholder loans, and transferring investments to a separate holding company on a tax-deferred basis under section 85. Because the test looks back 24 months, purification generally has to be substantially complete well before a sale process begins.
How long before selling should I start LCGE planning?
Ideally 24 months or more before the target closing date. The QSBC test includes a 24-month holding period and a 24-month active-asset test, so a corporation that is offside today generally cannot be fixed on the eve of a sale. Owners who wait until a buyer appears often discover that part or all of the exemption is out of reach for that transaction.
Can both spouses claim the lifetime capital gains exemption?
Yes, where each spouse or common-law partner genuinely owns shares that independently meet the QSBC test, each can claim their own exemption, which in 2026 can shelter more than $2.5 million of combined gains. But the ownership has to be real and properly structured. If one spouse simply transfers or gifts shares to the other, the attribution rules, including subsection 74.2(1) of the Income Tax Act, can attribute the capital gain back to the transferor, defeating the plan. Structure and paper the ownership early, with tax advice.
Can a family trust multiply the LCGE?
A discretionary family trust that holds QSBC shares can allocate capital gains to individual beneficiaries, and each beneficiary who is a natural person may be able to apply their own exemption to the allocated gain. The trust itself cannot claim the exemption. Attribution rules, including subsection 75(2), the tax-on-split-income regime, and the trust's 21-year deemed disposition rule all have to be managed, and CRA scrutinizes these structures. Trust multiplication works, but only with careful drafting and ongoing administration.
Does claiming the LCGE trigger alternative minimum tax?
It can. Under the alternative minimum tax rules that apply for 2024 and later years, a portion of capital gains sheltered by the exemption is included in the AMT calculation, so a large exempt gain can still produce a minimum-tax liability in the year of sale. AMT paid is generally recoverable against regular tax over the following seven years, but the cash-flow effect belongs in the sale model. Your accountant should run the AMT numbers before closing, not after.
Do I have to claim the whole exemption at once?
No. The exemption is a cumulative lifetime limit, not a one-time election. You can use part of it on one disposition and the balance later, and it is claimed as the capital gains deduction on your personal return (line 25400, calculated on Form T657) for the year of the sale. Amounts claimed in earlier years, including under the lower historical limits, reduce the room that remains.
Final thoughts
The lifetime capital gains exemption is one of the most valuable tax benefits available to a Canadian business owner, and it is also one of the easiest to lose without noticing. The three-part QSBCS test, the passive-asset thresholds and the 24-month look-back mean that eligibility is almost always the product of deliberate planning done years ahead, not luck discovered at closing.
If a sale is even a possibility in the next two to three years, the time to test your corporation's active-asset ratio and map the purification options is now. I advise Ontario business owners on the corporate and transactional side of selling a business, working alongside your accountant so the deal structure actually delivers the exemption the plan assumed.
