Business Exit Planning: How to Maximize Your Sale Price

Why Exit Planning Is a Tax Problem, Not Just a Business Problem

Most business owners think about exit planning in terms of valuation: how do I grow EBITDA, reduce customer concentration, build a management team, and make the business sellable? That's important. But for Canadian business owners, exit planning is equally a tax optimization problem. The difference between a well- structured exit and a poorly structured one can be $200,000–$500,000 in taxes on a modest $1–2M transaction.

The primary lever is the Lifetime Capital Gains Exemption. The secondary lever is share structure — specifically, whether the sale is structured as a share sale (where the LCGE applies) or an asset sale (where it doesn't). Getting both right requires planning that happens years before the transaction closes, not weeks.

The Lifetime Capital Gains Exemption: What It Is and What It's Worth

The LCGE allows every Canadian resident to shelter capital gains from qualifying small business corporation (QSBC) share sales up to a lifetime limit. In 2025, that limit is $1.25 million per person. With a 50% capital gains inclusion rate, $1.25 million in exempt gains means $625,000 never enters your taxable income. At a 50% marginal rate, that's approximately $312,500 in tax never paid.

A married couple where both spouses own shares can each claim the full exemption — effectively sheltering $2.5 million in combined capital gains. This is one reason why holding shares in both spouses' names, or in a family trust that allocates gains to multiple beneficiaries, is a common exit planning strategy.

The exemption is indexed to inflation annually, so the $1.25M limit will increase slightly each year. But don't count on indexation to do the heavy lifting — the qualification requirements are the real work.

QSBC Share Qualification: The Tests You Need to Pass

The LCGE only applies to Qualifying Small Business Corporation (QSBC) shares. Not every incorporated business automatically qualifies. The CRA applies three tests.

The 90% test: at the time of sale, at least 90% of the fair market value of the corporation's assets must be used in an active business carried on primarily in Canada. This means excess cash, investment portfolios, or passive real estate inside the operating company can cause disqualification if they grow too large relative to the operating assets.

The 50% test: throughout the 24-month period before the sale, more than 50% of the corporation's assets must have been used in active business operations. This is why the holding period matters — a corporation that recently converted passive assets to active use might not meet this test.

The holding period test: the shares must not have been owned by anyone other than the seller or a related person during the 24 months before the sale. Shares recently issued or transferred may not qualify without additional structuring.

Asset Sale vs. Share Sale: The Negotiation Every Owner Faces

Buyers almost always prefer asset sales. When a buyer acquires assets rather than shares, they get a stepped-up cost base on depreciable assets, can claim capital cost allowance (depreciation) on the full purchase price, and don't inherit unknown corporate liabilities. For the buyer, an asset deal is cleaner.

For the seller, an asset sale is materially worse. The corporation pays corporate tax on any capital gains or recaptured depreciation inside the company. What remains after corporate tax is then paid out to the shareholder as a dividend or on wind-up — taxed again at personal rates. The LCGE doesn't apply. The total tax on the proceeds of an asset sale can be 40–55% of the gain, versus roughly 0–25% on a qualifying share sale using the LCGE.

The standard negotiating approach: accept the asset sale structure but demand a price premium — often called an "asset sale premium" — to compensate for the additional tax burden. Depending on deal size and asset mix, this premium can range from 10–25% of the headline price. A tax advisor with M&A experience can model the exact number for your transaction.

When to Start Exit Planning

The 24-month holding period for QSBC share qualification is a hard floor. If you want to use the LCGE, the shares must have been structured correctly and the balance sheet must pass the asset composition tests — and those conditions need to be in place for at least two years before closing.

Beyond minimum qualification, three to five years of advance planning allows for a corporate purification strategy (moving excess passive assets into a holdco), an estate freeze to transfer future share appreciation to family members at today's value, share restructuring to multiply the number of shareholders who can claim the LCGE, and business improvements that raise the EBITDA multiple a buyer will pay.

If you think you might sell in the next five years, the time to start this conversation with your accountant is now. The tax benefit on a $1M+ transaction is large enough that even one year of advance planning pays for itself many times over.
