A buy-sell clause creates an obligation to buy a deceased shareholder's shares. It does not, by itself, create the cash to do it. Life insurance is the standard bridge between the two, and which of its two basic structures a company chooses changes who pays the premiums, who owns the policy, and how much tax the payout loses on the way to the seller's estate.
Key takeaways
Treadstone Law frames it precisely: the buy-sell obligation exists whether or not anyone has the cash to meet it, and “the surviving owners are obligated to buy the deceased's shares, but they need cash to actually do it.” A company that has never funded that obligation is betting that the estate will accept an IOU, or that the survivors can raise the price from a bank on short notice, at the exact moment the business has just lost one of its owners.
The two structures are described in the same source: in a cross-purchase, the individual shareholders personally acquire and hold policies on each other's lives; in a corporate redemption, the company itself buys and maintains the policies and redeems the deceased's shares directly. The choice “determines who pays the premiums and how the payout is used.” With more than two or three shareholders, cross-purchase also multiplies the number of policies needed — each shareholder has to own a policy on every other shareholder — which is one practical reason larger groups lean toward corporate redemption even before the tax question below is considered.
The policy count under a pure cross-purchase structure grows faster than the shareholder count. With three shareholders, six policies are needed — each of the three owning one on each of the other two. With four shareholders it is twelve; with five, twenty. A trust holding a single policy on each life, with the trust itself paying the surviving owners on a death, is one common way groups avoid that multiplication once they outgrow two or three owners, though it introduces its own drafting and administration questions outside what is covered here.
Premium payment is not a neutral detail. Under corporate redemption, the corporation pays the premiums out of its own funds — funds that would otherwise be available for the business or for ordinary dividends — and the policy sits as a corporate asset until it is needed. Under cross-purchase, each shareholder pays the premiums personally on the policies they own on the others, which means the cost is borne unevenly if the shareholders are different ages or in different health, since the same coverage amount costs more to insure an older or higher-risk shareholder. That asymmetry is one of the reasons cross-purchase agreements sometimes equalize premium contributions across the group rather than leaving each shareholder to pay only for the policies they individually hold.
Treadstone Law states the legal floor directly: “a valid insurable interest between the parties is required under Ontario insurance law” for a policy to be enforceable. A corporation generally has an insurable interest in the life of a shareholder whose shares it is obligated to redeem; individual shareholders under a cross-purchase structure need the same thing established between each pair before the policies are written, not discovered as a defence the insurer raises after a claim.
This is where corporate redemption earns its complexity. Under ITA s.89(1)(d), a private corporation's capital dividend account is credited with the life insurance proceeds it receives “in consequence of the death of any person,” reduced by “the adjusted cost basis…immediately before the death” of the policy. What lands in the CDA can then be paid out to shareholders as a capital dividend — a distribution that is not taxable income in the recipient's hands. In effect, the gap between the payout and the policy's adjusted cost basis passes through the corporation and into the estate's pocket without a further layer of corporate-level income tax eroding it on the way.
A cross-purchase structure has no equivalent mechanism: the proceeds land directly with the individual policyholders who used them to buy the deceased's shares personally, so there is no corporation, and no capital dividend account, in the transaction at all. The CDA credit is specifically a reason a corporate buyer, weighing the two structures, might prefer to own the policies itself rather than push ownership down to the individual shareholders.
The funding only works if the coverage amount tracks the company's value. Treadstone Law's warning is blunt: “a business that grows in value can leave an older policy well short of what's actually needed to fund the buyout.” A policy sized to a five-year-old valuation, left unreviewed, can leave the survivors short of cash and the estate short of what the buy-sell clause actually promised — which is also why the valuation formula itself needs periodic recomputation, not just the insurance behind it.
Everything above is specific to death. A shareholder who becomes disabled rather than dies creates a structurally similar funding problem — the survivors still need cash to complete a buyout — but the insurance product, the trigger and the tax result are all different, starting with the fact that s.89(1)(d)'s wording is tied specifically to a death benefit.
The capital dividend account, worked through
To show the mechanics only, not to state a market premium or payout figure: say a corporation is the named beneficiary on a policy insuring one shareholder, the policy pays out $1,000,000 on death, and its adjusted cost basis immediately before death was $40,000 — both illustrative numbers chosen only to make the arithmetic legible.
The corporation can pay that $960,000 to its shareholders — including the deceased's estate, on the redemption — as a tax-free capital dividend, rather than as an ordinary taxable dividend that would be eroded by the recipient's own income tax on the way through.
It depends which structure the agreement uses. Under a corporate redemption structure the company itself owns and pays for the policies and redeems the shares directly; under a cross-purchase structure, the individual shareholders personally own policies on each other and buy the shares themselves with the proceeds.
Life insurance proceeds a corporation receives in consequence of a shareholder's death are not corporate income, and under ITA s.89(1)(d) the amount above the policy's adjusted cost basis credits the corporation's capital dividend account, which can then be paid out to shareholders as a tax-free capital dividend.
There is no fixed statutory schedule, but Treadstone Law's guidance is to treat the valuation behind the coverage as a moving target: a business that has grown since the policy was written can leave the payout well short of the buyout price the clause actually requires, so coverage should be revisited whenever the underlying share value is revisited.
