Insurance Planning Inside a Professional Corporation: What Doctors, Dentists, Lawyers and Accountants Should Know

Incorporated professionals face a distinct set of insurance questions inside their professional corporation, from tax-efficient estate planning to protecting practice overhead and planning for a partner's absence.

Why a Professional Corporation Changes the Insurance Conversation

Doctors, dentists, lawyers, accountants and other licensed professionals who incorporate through a professional corporation face a different set of considerations than a typical small business owner. Provincial rules usually restrict who can hold voting shares to licensed professionals, and sometimes certain family members or trusts, and many PCs retain earnings inside the corporation to take advantage of the lower small business tax rate. Both of these factors change how insurance ownership and coverage amounts are best structured.

Corporate-Owned Life Insurance Inside a PC

Rather than leaving retained earnings sitting entirely in passive investments inside the PC, some professionals use a portion of that retained capital to fund a corporately owned permanent life insurance policy. Cash value inside the policy can grow on a tax-efficient basis, and on death, much of the payout can typically be credited to the corporation's Capital Dividend Account, allowing a tax-efficient capital dividend to flow to the professional's estate or family. This is a long-term estate planning tool that works alongside, not instead of, the professional's other retained earnings and investment strategy.

Protecting the Practice: Disability and Overhead Coverage

A professional's ability to earn is central to keeping the practice's overhead paid. If a disabling illness or injury sidelines the professional, rent or mortgage on the office, staff salaries, equipment leases, and property taxes continue whether or not the professional can work. Business overhead expense insurance is designed specifically to cover those fixed costs during a period of disability, and premiums are tax-deductible for both sole proprietors and corporations, which helps make this coverage a straightforward addition alongside the professional's own personal disability insurance.

Key Person Considerations in a Small Partnership-Style Practice

Many professional practices, a dental office, a small law firm, an accounting partnership, operate with two to five professionals sharing space, staff, and sometimes a client base. The sudden death or disability of one partner can disrupt patient or client relationships and referral goodwill well beyond that partner's own workload. Key person insurance on each partner gives the practice funds to bridge the gap, whether that means hiring locum coverage, recruiting a replacement, or simply keeping the lights on while a longer-term buy-sell or succession arrangement between the partners' respective corporations is worked through.

  • Confirm who can legally own shares and hold insurance given your province's professional corporation rules
  • Coordinate any key person or corporate-owned life insurance with the practice's existing buy-sell or partnership agreement
  • Size business overhead expense coverage to the practice's actual fixed costs, not simply the professional's personal income
  • Revisit coverage as the practice adds partners, staff, or additional locations

Frequently Asked Questions

Why is insurance planning different for a professional corporation compared to an unincorporated practice?

A professional corporation often retains earnings inside the company for tax deferral, and share ownership is usually restricted to licensed professionals and, in some provinces, certain family members or trusts. This changes how life insurance ownership, corporate cash, and overhead protection are best structured compared to an unincorporated sole practitioner.

How does corporate-owned life insurance work inside a professional corporation?

Retained earnings inside the PC can fund a corporately owned permanent life insurance policy, allowing cash value to grow on a tax-efficient basis inside the corporation and eventually delivering a death benefit that can be paid out to heirs in a tax-efficient way, often as an alternative to simply holding passive investments inside the corporation.

What does business overhead expense insurance cover for a professional practice?

Business overhead expense insurance is designed to cover fixed practice costs such as rent or mortgage payments, staff salaries, equipment leases, and property taxes if the professional becomes disabled, so the practice can keep operating or be wound down in an orderly way rather than facing overhead costs with no income coming in.

How does key person insurance apply in a small partnership-style practice like a dental or law office?

In a practice with a handful of partners, the sudden death or disability of one partner can disrupt client relationships, revenue, and referral goodwill. Key person insurance on each partner provides funds to absorb that disruption and hire replacement help while a longer-term buy-sell or succession plan plays out.

Does DMPG advise on the legal structure of my professional corporation?

No. Decisions about share structure, professional corporation rules in your province, and how shares can legally be held are matters for your lawyer and accountant. DMPG's role is to design the insurance strategies, corporate-owned life insurance, business overhead expense coverage, and key person protection, that fit around that structure.
