The $1.275 million lifetime capital gains exemption most incorporated professionals still don't understand

If family members are also able to claim the exemption, the tax benefits can be even larger. Two spouses each claiming the full exemption could shelter up to $2.55 million in gains from a single business sale.

But it’s not an automatic exemption. Your shares must meet specific requirements under the Income Tax Act, and many incorporated professionals, including physicians, consultants, lawyers and other business owners fail to confirm whether their shares actually qualify. It’s a problem you can avoid with some proper planning.

What is the LCGE and who is eligible?

The LCGE is a lifetime tax exemption available to Canadian individuals who sell shares of a qualified small business corporation (QSBC). In 2024, the exemption ceiling was increased to $1.250 million. The increase was reaffirmed in Budget 2025, with indexation resuming in 2026, when it was increased to $1.275 million. The capital gains inclusion rate remains at 50% for individuals, following the cancellation of the proposed increase to 66.67% in March 2025.

To claim the exemption, you must be a Canadian resident individual. Corporations cannot claim the deduction directly. Eligible property includes QSBC shares as well as a qualified farm or fishing property. The deduction is claimed on line 25400 of your personal tax return.

Eligible professionals could unlock up to $1,313 in annual savings with National Bank’s special offer for professionals — including up to 3 bank accounts with no fixed monthly fees, with an eligible Mastercard rewards credit card (Certain fees apply). Make an appointment to explore your options.

The three tests your shares must pass

Not every share in a Canadian corporation qualifies for the LCGE. To be considered QSBC shares under the Income Tax Act, the following conditions must be met both at the time of sale and during the 24 months leading up to the sale.

• The 90% Active-Business test: At the time of sale, at least 90% of the fair market value of the corporation’s assets must be attributable to active business assets used primarily in Canada, or shares and debt of connected small business corporations. Excess cash, passive investments and rental properties can create problems here.
• The 50% Asset-Use test: During the entire 24 months before the sale, at least 50% of the corporation’s assets must have been used in an active business carried on primarily in Canada.
• The Holding-Period test: The shares cannot have been owned by anyone unrelated to the individual at any point in the 24 months before the sale. This can become a factor after certain corporate reorganizations or when new shares are issued.

The corporation must also qualify as a Canadian-controlled private corporation (CCPC) throughout the relevant period. This means that it cannot be publicly traded and control must remain with Canadian residents.

Why passive investments can disqualify you

One of the most common LCGE traps for incorporated professionals is the accumulation of passive assets inside the corporation. After years of retained earnings, many corporations build substantial balances of cash, GICs, investment portfolios, or real estate. While these assets can be highly beneficial, they generally don’t count as active business assets for LCGE purposes.

In this hypothetical example, let’s say a physician who incorporated 10 years ago has accumulated $600,000 in a corporate investment portfolio alongside their active medical practice. If those passive investments represent 35% of the corporation’s fair market value at the time of a planned sale, the corporation would fail the 90% test. As a result, the shares would not qualify for the LCGE.

The solution is a process called “purification”, which involves transferring non-active assets out of the operating corporation to a holding company, typically on a tax-deferred basis using rollover provisions in the Income Tax Act. However, this takes time and requires both legal and accounting expertise. For this reason, you really need to begin the process at least two years before a planned sale.

Family share multiplication: sheltering more than $1.275 million

The LCGE applies to individuals, not corporations. When structured properly, multiple family members can each claim their own LCGE on the same business sale. It’s a strategy known as share multiplication.

In another hypothetical example, if a married couple each holds qualifying shares of the same CCPC, both spouses may be able to claim the full $1.275 million exemption. Together, they could shelter $2.550 million in capital gains from tax on a single business sale. If adult children also own qualifying shares, the sheltered amount could rise even further.
