Most multi-owner private corporations have some version of a shareholder agreement addressing what happens on death, disability, or a decision to leave. Far fewer have actually funded that agreement in a way that survives contact with reality, leaving a surviving partner legally entitled to buy out a departed shareholder's estate with no clear source of the cash to do it.
Key Takeaway
A buy-sell agreement without a funding mechanism is a plan to owe money, not a plan to pay it. Life insurance, held either personally or corporately depending on the structure chosen, is the standard tool for making sure the obligation and the cash to satisfy it arrive at the same time.
The Problem A Buy-Sell Agreement Solves
Without a binding agreement, the death or departure of a shareholder in a private corporation can leave the remaining owners in business with an estate, a former spouse, or an entirely disengaged party they never chose as a partner. A buy-sell agreement fixes the mechanics in advance: a triggering event occurs, a valuation method is applied, and a purchase obligation is created. What it does not automatically solve is where the purchase price actually comes from.
Two Ways To Structure It
Buy-sell funding generally takes one of two forms, each with materially different tax consequences:
- Cross-purchase agreement. Each shareholder personally owns a life insurance policy on the other shareholder(s) and uses the proceeds to buy the deceased's shares directly. The surviving shareholder's cost base in the purchased shares increases by the price paid, which matters considerably on a future sale.
- Corporate redemption agreement. The corporation itself owns the life insurance on each shareholder and uses the proceeds to redeem the deceased's shares from their estate. This is administratively simpler with more than two shareholders, since it avoids each owner needing a policy on every other owner.
A hybrid structure is also common: the corporation owns the policies but grants each shareholder an option to purchase directly, preserving flexibility to choose the more tax-efficient route once the actual circumstances of a triggering event are known.
Why Life Insurance Specifically
Life insurance is the only funding mechanism that guarantees the cash arrives at exactly the moment the obligation is triggered by death, regardless of how long the shareholder has held shares or how the corporation's own cash position looks that year. A sinking fund or corporate savings account can fall short if death occurs early; a properly sized policy cannot.
The Capital Dividend Account Advantage
Where the corporation owns the policy, life insurance proceeds received on death generally credit the corporation's Capital Dividend Account for the amount by which proceeds exceed the policy's adjusted cost basis. That CDA balance can then be paid out to the surviving shareholders, or to the deceased's estate, as a tax-free capital dividend, a meaningfully more efficient outcome than an equivalent amount paid as a taxable dividend or salary.
What Most Agreements Get Wrong
The most common failure is not the absence of an agreement, it is a stale one: coverage amounts set years ago that no longer reflect current valuation, a corporate redemption structure that was never actually funded with a policy, or an agreement that assumes a specific tax treatment without confirming it still applies under current rules. A buy-sell agreement is only as reliable as the funding behind it and the frequency with which both are actually reviewed.
