For many successful incorporated business owners, the most tax-efficient way to pass wealth to the next generation isn't through their RRSP, their investment portfolio, or even their will. It's through corporate-owned permanent life insurance — a strategy that turns retained corporate earnings into a tax-free legacy while providing genuine insurance protection along the way.
What is corporate-owned life insurance?
Corporate-owned life insurance (COLI) is exactly what it sounds like: a life insurance policy where the corporation is both the owner and the beneficiary, and the insured is the business owner (or another key person).
- The corporation pays the premiums — using after-corporate-tax dollars
- The policy accumulates cash value inside the corporation — growing tax-sheltered
- On the death of the insured, the death benefit is paid tax-free to the corporation
- The proceeds flow to shareholders through the Capital Dividend Account — tax-free
Key tax advantages
The COLI strategy's power comes from two compounding tax advantages:
Tax-sheltered growth inside the policy
The policy's investment component grows tax-sheltered — unlike a corporate investment account where growth is taxed annually. For a corporation in the top marginal rate, this tax deferral can be extremely valuable over 10–20 years.
Tax-free distribution through the CDA
When the death benefit is paid to the corporation, it flows into the Capital Dividend Account (CDA). Amounts in the CDA can be distributed to shareholders as capital dividends — completely tax-free. This turns what would have been heavily taxed corporate retained earnings into a tax-free inheritance.
Simplified comparison
Without COLI: $500,000 of retained corporate earnings eventually distributed as dividends → significant personal tax → perhaps $300,000–$350,000 reaches heirs.
With COLI: $500,000 in premiums funds a policy with a $1,000,000 death benefit → flows through CDA → $1,000,000 reaches heirs tax-free. The insurance leverage transforms both the amount and the tax outcome.
The Capital Dividend Account explained
The Capital Dividend Account is a notional account that tracks certain tax-free amounts earned by a private corporation. Life insurance proceeds paid to a corporation increase the CDA by the amount of the death benefit less the policy's adjusted cost base (ACB). Shareholders can then elect to receive capital dividends — tax-free — up to the CDA balance.
The ACB is the cumulative cost of the policy's mortality charges over time. For permanent policies with growing cash values, the ACB can be much less than the death benefit, resulting in a large CDA credit.
Who benefits most?
- Business owners with significant retained earnings they don't need for business operations
- Owners who have maximized RRSP and TFSA contributions and need another tax-sheltered vehicle
- Business owners with estate planning goals — wanting to leave tax-efficient wealth to children or grandchildren
- Shareholders who plan to hold the corporation for life rather than sell — COLI is most effective when held long-term
- Those with a family trust who want to direct the CDA capital dividends strategically
How the strategy works in practice
Review retained earnings and cash flow
Carrie reviews the corporation's financial position to determine how much can be directed to insurance premiums without impacting operations.
Choose the right policy type
Permanent coverage — Sun Life Par or Universal Life — is typically used. The policy type affects the premium, cash value growth, and dividend participation.
Optimize premium and coverage amount
The premium is designed to maximize cash value accumulation and CDA credit within the constraints of the policy and tax rules.
Integrate with the estate plan
The COLI strategy is coordinated with the owner's will, shareholder agreement, and other estate planning documents to ensure the CDA capital dividends flow as intended.
Review annually
As the business, the policy, and the tax rules evolve, annual review ensures the strategy continues to optimize for the owner's goals.
Carrie's expertise: Corporate life insurance planning is one of the most technically complex areas of financial planning — and one of the highest-value conversations Carrie has with incorporated business owners. If you have significant retained earnings and want to understand whether COLI makes sense for your situation, book a consultation. The analysis is free and may reveal a strategy worth substantially more than it costs.
