Lifetime capital gains exemption: 2026 guide for Canadians

The lifetime capital gains exemption (LCGE) shelters qualifying capital gains from federal tax for eligible Canadian individuals. For 2026, the indexed limit sits at approximately $1,275,000 per taxpayer, up from the $1,250,000 base introduced by the 2024 federal budget for dispositions on or after June 25, 2024. That is a per-person figure, which means a couple who each hold qualifying shares can shelter double the capped amount combined.

Two things to check right now:

• QSBC status: Do your shares meet the three qualifying small business corporation tests under Income Tax Act s. 110.6?
• CNIL room: Does your Cumulative Net Investment Loss balance reduce your available exemption?

If either answer is unclear, the sections below walk through exactly what to look for.

What property qualifies for the lifetime capital gains exemption?

The LCGE applies to three categories of property under CRA Guide T4037:

1. Qualifying small business corporation (QSBC) shares
2. Qualified farm property
3. Qualified fishing property

Most Alberta business owners are working with QSBC shares, so that is the focus here. The critical structural point: the exemption applies to a share sale, not an asset sale. When a buyer purchases your company’s assets directly, the gain is realized inside the corporation and taxed at corporate rates, with no LCGE available to the individual shareholder. A share sale, by contrast, puts the gain in your hands personally, where the LCGE can offset it.

A quick illustration: if you sell the shares of your incorporated Alberta consulting firm and the shares qualify, you can apply the LCGE. If the buyer insists on an asset purchase and you agree without restructuring, the exemption is gone entirely.

The three QSBC tests you must pass at sale

Section 110.6 of the Income Tax Act sets out three hard statutory tests. Failing any one of them disqualifies the shares.

• Test 1 (at-sale test): — At the time of sale, at least 90% of the fair market value (FMV) of the corporation’s assets must be active business assets used primarily in Canada.

Where owners run into trouble: a company that accumulated excess cash, GICs, or a rental property inside the corporation will often fail Test 1 or Test 2 because those passive assets count against the active-business threshold. A sudden reorganisation or new share issuance shortly before closing can also break Test 3 if the timing is not managed carefully.

Pro Tip: Run a balance sheet analysis at least 12 months before your target sale date. If passive assets exceed 10% of FMV, you have a purification problem to solve before the clock runs out.

How to claim the deduction: Schedule 3, line 25400, and Form T657

The filing process follows a clear sequence, and your accountant will handle each step on your T1 return.

2. Calculate the deduction on line 25400 — using CRA’s capital gains deduction guidance, which requires you to attach a completed Form T657.

When a family trust holds the shares and allocates the gain to beneficiaries, the trust files a T3 return and each beneficiary claims the LCGE on their own T1. Timing the trust’s fiscal year-end and the allocation resolution matters here, so involve your accountant well before the sale closes.

Understanding your LCGE room: limits, indexing, and CNIL

The 2024 federal budget raised the LCGE base to $1,250,000 for qualifying dispositions on or after June 25, 2024, indexed to CPI from 2026. The 2026 indexed figure is approximately $1,275,000 per eligible individual.

Your usable room is not simply the headline limit. Two accounts can erode it significantly:

CNIL (Cumulative Net Investment Loss): If your investment expenses (interest on money borrowed to invest, rental losses, etc.) have exceeded your investment income over your lifetime, you carry a positive CNIL balance. That balance reduces your available LCGE dollar-for-dollar. Many sellers discover a CNIL problem only at filing, when it is too late to fix.

Historical allowable capital losses: Prior net capital losses applied against other income can also reduce your LCGE room. Review your Notice of Assessment history or ask CRA for your loss carryforward balance before you sign a purchase agreement.

Pro Tip: Request a CNIL calculation from your accountant the moment you begin thinking about a sale. Correcting a CNIL problem takes time, and you cannot undo it retroactively.

A worked example: LCGE in action

Assume an Alberta business owner sells QSBC shares in 2026. The numbers:

Without the LCGE, the full — capital gain would produce a taxable capital gain of $750,000 under the 50% inclusion rate in Subdivision C of the Income Tax Act. At Ontario’s combined top marginal rate, sheltering the $1,275,000 with the LCGE saves more than $340,000 in tax. Alberta’s combined top marginal rate produces a comparable result.

Common mistakes that cost sellers their exemption

• Leaving excess cash, GICs, or rental properties inside the corporation past the 24-month window
• Transferring shares to a spouse or child less than 24 months before closing
• Failing to calculate CNIL before signing the purchase agreement
• Structuring the deal as an asset sale without exploring a share sale alternative
• Executing an estate freeze without confirming the new shares will meet the ownership test by sale date
• Overlooking historical capital loss balances that reduce LCGE room
• Missing the T3 filing deadline when a family trust is involved, which can delay beneficiary claims

If any of these apply to your situation, raise them with your adviser immediately. CRA reassessments on LCGE claims are not uncommon, and the documentation burden falls on you.

Key takeaways

The lifetime capital gains exemption can shelter up to approximately $1,275,000 of qualifying capital gains per eligible Canadian individual in 2026, but only if the shares meet all three QSBC tests and your CNIL account does not erode your available room.

The part most owners get wrong

The LCGE is one of the most valuable tax provisions in the Canadian Income Tax Act, and yet the majority of business owners who lose access to it do not lose it because of a complex legal issue. They lose it because of timing. A rental property sitting inside the corporation for one month too long, a share transfer that happened 22 months before closing instead of 25, a CNIL balance nobody checked until the deal was already signed.

The 2024 budget increase to $1,250,000 and the ongoing CPI indexation make the stakes higher than ever. At the 2026 limit, a single owner who fails to qualify loses the ability to shelter a gain that could otherwise be almost entirely tax-free. For a family with three qualifying shareholders, the aggregate cost of a planning failure is measured in seven figures.

What advisers see repeatedly is owners who treat the LCGE as something to claim at filing rather than something to earn through two-plus years of deliberate structuring. The filing is the last step, not the first. The work happens long before the purchase agreement is signed, in balance sheet reviews, ownership restructurings, and CNIL calculations that most owners would rather not think about until they have to.

A virtual CFO who understands this timeline does not wait for the deal to arrive. They are already running the asset-use analysis, flagging the passive investment problem, and coordinating with the corporate lawyer on the purification plan. That is the difference between a clean LCGE claim and a CRA reassessment two years after closing.

FAQ

What is the LCGE limit for 2026?

The lifetime capital gains exemption limit for 2026 is approximately $1,275,000 per eligible individual.

Does the LCGE apply to an asset sale?

No. The LCGE applies only when an individual sells qualifying shares. An asset sale generates a gain inside the corporation, where the exemption is not available.

What is CNIL and how does it affect my LCGE?

CNIL stands for Cumulative Net Investment Loss. A positive CNIL balance reduces your available LCGE dollar-for-dollar, so reviewing it before closing is critical.

Can multiple family members each claim the LCGE on the same company?

Yes, if each family member holds qualifying shares independently and meets all three QSBC tests. A family trust can also allocate gains to multiple beneficiaries, each claiming their own exemption, subject to TOSI and attribution rules.

Where do I report the LCGE on my tax return?

Report the capital gain on Schedule 3 of your T1, claim the deduction on line 25400, and attach a completed Form T657. CRA Guide T4037 provides detailed instructions for each step.
