Corporate-Owned Life Insurance: The Tax Benefits Physicians and Dentists Overlook

Most incorporated physicians and dentists think of life insurance purely as protection — something that pays out if something happens to you. Held inside a professional corporation, it can also play a role in tax and estate planning that’s easy to overlook. Here’s how that works, and where the limits are.

Why hold insurance inside the corporation at all

A corporation can generally pay life insurance premiums with corporate dollars rather than the shareholder paying with dollars that were already taxed personally, which can make coverage meaningfully more efficient to fund — particularly at higher personal tax brackets. For many incorporated professionals, this alone is worth understanding even before considering the tax planning uses below.

The Capital Dividend Account: how a death benefit can pass out tax-free

When a corporation is the beneficiary of a life insurance policy on a shareholder, the death benefit received by the corporation typically exceeds the policy’s adjusted cost basis (ACB), and that excess generally credits the corporation’s Capital Dividend Account (CDA). Amounts in the CDA can then be paid out to shareholders (or their estate) as a capital dividend — without personal income tax on that dividend. In effect, this can allow a life insurance benefit to flow from the corporation to your estate largely tax-free, which is one of the more significant advantages of corporate-owned coverage.

Funding a buy-sell agreement between practice partners

If you co-own a practice with one or more partners, corporate-owned life insurance is a common way to fund a shareholders’ or buy-sell agreement — ensuring that if a partner dies, the surviving partner(s) or the corporation have the funds available to buy out that partner’s shares from their estate, without having to find that capital elsewhere or force a sale of the practice under pressure.

Using retained earnings more efficiently

Incorporated professionals who accumulate significant retained earnings inside their corporation face a tradeoff: passive investment income earned on those retained earnings above certain thresholds can reduce access to the small business tax rate. For corporations already holding more passive investments than needed for near-term practice needs, redirecting some portion of that surplus into an exempt life insurance policy can be one option worth exploring, since the policy’s internal growth is generally not taxed annually the way a typical investment account would be. This isn’t the right fit for every corporation, and it works best as part of a broader retained-earnings strategy rather than a stand-alone decision.

What to watch for

• Corporate-owned insurance is illiquid — it isn’t a substitute for maintaining reasonable operating cash and short-term liquidity in the practice.
• The CDA credit and its tax treatment depend on the policy’s structure and adjusted cost basis calculations, which should be confirmed with your accountant and the insurer, not assumed.
• This works best when coordinated with a shareholders’ agreement, your will, and your accountant’s corporate tax filings — not set up in isolation.
• Policy design (permanent vs. term, funding level, ownership structure) needs to match your actual goal, whether that’s estate transfer, buy-sell funding, or retained-earnings efficiency — these can call for different structures.

Where this fits into your broader plan

Corporate-owned life insurance is one of several tools incorporated professionals use alongside a holding company structure (see our article on holding companies vs. operating companies) and broader retained-earnings planning. It tends to work best as a deliberate piece of an overall corporate and estate strategy, not a product bought on its own.
