For Canadian business owners contemplating an eventual sale, the Lifetime Capital Gains Exemption is the largest single planning tool. The current 2024 amount of $1,016,836 (indexed) per individual shelters significant gain — and when multiplied across family members through a properly-structured trust, the exemption can absorb the full taxable gain on a mid-market sale.
What the exemption shelters
Section 110.6 of the Income Tax Act provides a lifetime capital gains exemption on the disposition of qualifying small-business-corporation (QSBC) shares. To qualify as QSBC at the moment of sale, three conditions must be met:
- 90% test — at the time of disposition, 90%+ of the corporation's FMV must be active-business assets used in Canada.
- 50% test — throughout the 24 months immediately before disposition, 50%+ of the corporation's assets must have been active-business assets.
- 24-month holding test — the shares must have been held for at least 24 months by the seller (or a related person).
If all three tests are met, up to $1,016,836 of capital gain per claimant is exempt from tax. At a 50% inclusion rate and Ontario top marginal rates, the exemption saves roughly $137,000 of tax per claim.
The multiplier mechanic
The LCGE is granted on a per-individual basis. Each Canadian-resident individual has one lifetime exemption. The multiplier works by structuring the corporation's ownership so that multiple individuals each realize a portion of the sale gain — each then claiming their own LCGE.
The standard structure: a family discretionary trust holds the growth shares of the corporation. At sale, the trust allocates the capital gain on the share sale to multiple beneficiaries — typically the founder's spouse and children. Each beneficiary picks up their share of the gain in their personal tax return and claims their own LCGE against it.
The arithmetic on a real example
A Canadian business sells for $5M with $5M of net gain to a family discretionary trust holding the growth shares. The founder has structured the trust so that the gain can be allocated to: founder, spouse, three adult children. Each allocates $1M to one of the five claimants. Each claimant has their full $1,016,836 LCGE available (assuming none has been previously claimed).
Tax outcome: each $1M of gain is fully sheltered by the claimant's LCGE. Federal capital-gains tax on the $5M gain: zero (subject to AMT, discussed below). Without the multiplier — if the founder had owned the shares directly — only the founder's single $1,016,836 LCGE would apply; the remaining ~$4M of gain would be taxed at top capital-gains rates (~$540K federal/provincial tax).
The structure must be set up early
For the multiplier to work, the trust must hold the growth shares for at least 24 months before sale (the QSBC 24-month holding test) and the beneficiaries' QSBC eligibility must trace through the trust. A trust settled six months before sale doesn't qualify. Most planning windows are 24-36 months before the anticipated sale.
The structural moves typically involve an estate freeze (founder's common shares converted to preferred; trust receives new growth common shares), followed by the trust holding the growth for the 24-month testing window, followed by the sale at which the trust allocates the gain to beneficiaries.
The TOSI overlay
The tax-on-split-income (TOSI) rules in Section 120.4 apply to certain dividends and capital gains paid to family members. For LCGE multiplication, the relevant question is whether the allocated capital gain falls within a TOSI exception. Most family-trust allocations of capital gain on QSBC sales qualify under the "excluded business" or "excluded shares" exceptions or the various age-based exceptions, but the analysis has to be confirmed for each allocation.
The AMT cost
Claiming the LCGE produces preference items that feed the alternative minimum tax calculation. Most LCGE claims trigger some AMT in the claim year, recoverable over the subsequent seven years against regular tax. The 2024 federal budget broadened the AMT preference base and increased the rate, making the AMT cost of an LCGE claim materially larger than historically. For a mid-six-figure LCGE claim, the AMT cost can be in the high five figures — typically recoverable, but a meaningful cash-flow consideration in the claim year.
The 2024 budget changes
The 2024 federal budget enhanced the LCGE by raising the exemption from $1,016,836 to $1.25M (for qualifying farm/fishing property and QSBC shares disposed after June 25, 2024). For business sales closing after that date, the planning math is more generous than the historical numbers.
How we work the file
LCGE-multiplication planning sits within the broader business-owner planning engagement. The setup runs 24+ months before sale; the claim is coordinated with the deal team at sale time. The tax saved frequently exceeds the planning cost by an order of magnitude.
