For most businesses, the choice of entity is relatively open. But licensed professionals — physicians, attorneys, accountants, and others — often face special rules requiring them to use a professional entity, such as a professional corporation (PC) or professional limited liability company (PLLC), rather than a standard LLC or corporation. These structures have particular features and limits. This guide explains how professional entities work, who needs them, and what makes them different. Because rules vary by profession and jurisdiction, it’s general information, not a substitute for advice on your specific situation.

For many licensed professionals, the ordinary LLC isn’t an option.

What professional entities are

Professional corporations (PCs) and professional limited liability companies (PLLCs) are entity types designed for licensed professionals. They function similarly to standard corporations and LLCs — providing a formal entity structure — but are subject to special rules reflecting the professional nature of the business. As the Legal Information Institute’s overview of the law.cornell.edu and law.cornell.edu reflects, entity forms carry distinct legal characteristics, and professional variants add profession-specific requirements. These structures exist because many professions have rules governing how their practitioners may organize, which standard entities don’t satisfy. Understanding that a professional entity is a specialized version of a familiar structure is the starting point.

A professional entity protects you — but not from your own malpractice.

Who needs one

Whether you need a professional entity depends on your profession and jurisdiction. Many licensed professions — such as medicine, law, accounting, and others — require or restrict practitioners to professional entities when they incorporate or form an LLC, rather than allowing a standard entity. The specific rules, and which entity forms are available, vary significantly by profession and by state. So a licensed professional can’t assume a standard LLC is available or appropriate; they must check the rules governing their profession in their jurisdiction. As the SBA’s guidance on how to sba.gov reflects, choosing the right structure requires attention to the rules that apply to you — and for professionals, those rules are often specific.

Liability protection and its limits

Professional entities generally provide liability protection similar to standard entities — shielding owners’ personal assets from many business debts and liabilities — but with an important limit: they typically do not shield a professional from liability for their own professional malpractice. A professional remains personally responsible for their own negligent professional acts, even within a PC or PLLC. The entity can, however, still protect against many other business liabilities and, in some cases, the malpractice of other owners. Understanding this crucial limit — that the professional entity is not a shield against your own malpractice — is essential to having accurate expectations about what protection it provides.

Forming one correctly

Forming a professional entity involves the standard entity-formation steps plus profession-specific requirements, which may include ownership restrictions (often limiting owners to licensed members of the profession), naming rules, and approvals or registrations tied to the professional licensing body. Getting these details right matters, because a professional entity that doesn’t comply with the applicable rules can create problems. Because the requirements vary by profession and state and include specialized rules, licensed professionals benefit from legal guidance in choosing and forming the correct entity. Done properly, a professional entity gives a licensed practitioner an appropriate, compliant structure for their practice.
