Choosing Between a Professional Corporation (PC) and LLC for Licensed Professionals in Missouri
Licensed professionals in Missouri, such as doctors, CPAs, and architects, must navigate strict state regulations when choosing a business structure. While neither a PC nor a standard LLC will protect you from your own malpractice, they do shield your personal assets from partner negligence and general business debts.
When opening a private practice or a specialized firm in Missouri, licensed professionals cannot simply form a standard business entity without a second thought. State law strictly regulates how professions involving the public trust-such as medicine, law, and accounting-are structured. Choosing the wrong entity type can lead to rejected licenses, massive tax implications, and dangerous personal liability. To ensure your new firm complies with both the Secretary of State and your specific licensing board, you should browse our US Attorneys directory to hire a local lawyer who understands Missouri professional business laws.
The Corporate Practice of Medicine Doctrine in Missouri
Many states have a strict 'Corporate Practice of Medicine' (CPOM) doctrine, which prohibits laypeople (non-doctors) from owning medical clinics to prevent corporate profits from influencing medical decisions. Missouri follows a modified version of this doctrine. Under The Professional Corporation Law of Missouri, found in Mo. Rev. Stat. § 356.011 and governed by Mo. Rev. Stat. § 356.031, Missouri does not recognize a separate PLLC entity; professionals must form either a Professional Corporation (P.C.) or, if authorized by their governing licensing board, a standard LLC under Mo. Rev. Stat. § 347.037. Crucially, all shareholders of a P.C. must be actively licensed in the specific profession the business is rendering. A business executive cannot own 50% of a medical clinic with a physician in a Missouri PC.
Entity Choices for Specific Licensed Professionals
The rules dictate that you must file specialized formation documents with the state to operate legally. To incorporate a Professional Corporation, organizers submit Form Corp. 41, Missouri, Secretary of State, Articles of Incorporation of a For Profit Corporation accompanied by Form Corp. 76, Missouri, Secretary of State, Certificate of State Board Registration issued by the applicable regulatory board. The requirements vary depending on your oversight board.
Physicians and Dentists
Doctors overseen by the Missouri Board of Registration for the Healing Arts, Jefferson City generally opt for a Professional Corporation (PC) or, when permitted by licensing regulations, a standard LLC. In a medical PC, every single shareholder must be a licensed physician. If a doctor passes away, their shares cannot simply pass to their unlicensed spouse; the corporation must buy them back or transfer them to another licensed physician within a statutory timeline. This ensures that only medically trained individuals are making clinic decisions.
CPAs and Accountants
Accountants must register their firms with the Missouri State Board of Accountancy, Jefferson City. While CPAs frequently choose LLCs for tax flexibility, they must operate as a firm owned primarily by licensed CPAs. In some cases, a minority ownership by non-CPA employees is allowed, provided strict Board regulations regarding the firm's management are followed.
Architects and Engineers
Design professionals overseen by the Missouri Board for Architects, Professional Engineers, Professional Land Surveyors and Professional Landscape Architects, Jefferson City have slightly more flexibility but still frequently utilize Professional Corporations. They often collaborate on massive projects, meaning the corporate shield against a partner's design failure is absolutely critical.
Legal Practitioners
Lawyers forming a practice in Missouri also follow strict Supreme Court rules regarding entity formation. A law firm cannot have non-lawyer owners. Lawyers frequently form LLCs or PCs to shield their personal assets from the firm's commercial debts, such as an expensive office lease.
Personal Liability Exceptions for Professional Malpractice
The biggest misconception among professionals is the belief that forming a PC or an LLC protects them from malpractice lawsuits. Under Missouri law, specifically Mo. Rev. Stat. § 356.171, no corporate structure can shield a licensed professional from liability for their own personal negligence or malpractice. If a surgeon makes a fatal error, the patient can sue the surgeon personally, and the PC will not protect the surgeon's personal assets. This principle is consistent with medical liability precedents, heavily discussed in cases like Goff v. St. Luke's Hosp. of Kansas City, 753 S.W.2d 557 (MO Supreme Court 1988).
However, the PC or LLC is still vital. Why? It protects you from the 'vicarious liability' of your partners. If you and two other dentists share a practice, and one of your partners commits malpractice, the patient can sue the partner and the business, but your personal assets (your home, your savings) are shielded from your partner's mistake. Furthermore, the entity protects all owners from general commercial liabilities, such as a slip-and-fall in the waiting room or a breached contract with a medical supplier.
| Liability Scenario | Does the PC/LLC Protect You? |
|---|---|
| You commit professional malpractice | No. You are personally liable for your own actions. |
| Your business partner commits malpractice | Yes. Your personal assets are shielded from their mistake. |
| A patient slips in your waiting room | Yes. The entity shields you from general commercial claims. |
| Your firm defaults on a commercial lease | Yes (Unless you signed a personal guarantee). |
Frequently Asked Questions (FAQ)
What is the tax difference between a PC and an LLC?
A standard PC is taxed as a C-Corporation, meaning it pays corporate taxes on profits, and you pay taxes again on dividends (double taxation). An LLC provides pass-through taxation. However, a PC can elect S-Corp status to avoid double taxation.
Can a doctor and an accountant own a Missouri PC together?
No. Under Missouri Professional Corporation laws, a PC must generally be formed by individuals who are all licensed in the same specific profession. You cannot mix wildly different professional licenses in one PC.
Does the name of my firm matter?
Yes. The state requires a Professional Corporation to contain the words 'Professional Corporation' or the abbreviation 'P.C.' in its name. Additionally, your specific licensing board may restrict the use of trade names or require the owners' last names to be included.
If I form a PC, do I still need malpractice insurance?
Absolutely. Because a PC does not shield you from your own malpractice, maintaining a robust professional liability (malpractice) insurance policy is critical to protecting your personal wealth.
