PLLC vs. LLC: Which One Do Licensed Professionals Need?

A PLLC follows the same basic structure as a standard LLC — pass-through taxation by default, an operating agreement instead of corporate bylaws, and a state filing to create it — but ownership is restricted to people who hold the relevant professional license. Professions commonly required or permitted to use a PLLC include doctors and dentists, lawyers, accountants and CPAs, architects and engineers, and therapists and counselors, though the exact list of licensed occupations covered varies by state.

Only individuals licensed in the relevant profession can own or manage a PLLC in most states, and some states require every member to hold the license, not just a majority. That's the core difference from a standard LLC, which has no ownership restrictions at all: individuals, other companies, and even entities from outside the state can own or manage a regular LLC.

A PLLC protects members' personal assets from the business's general debts and from malpractice claims against other members, the same baseline protection a standard LLC provides. What it does not do is shield you from a malpractice claim based on your own professional work. If you make a professional error while providing services, you can still be held personally liable for that specific claim, regardless of the entity structure around you.

Because of that gap, many states that require or allow a PLLC also require members to carry professional liability (malpractice) insurance, sometimes with a specific minimum coverage amount, as a condition of forming or maintaining the entity.

Forming a PLLC typically requires everything a standard LLC filing needs, plus proof that the members hold the required professional license and, in many states, written approval or a certification from the relevant state licensing board before the Secretary of State will accept the filing. A standard LLC has no such approval step: file articles of organization, pay the fee, and the entity is formed.

PLLC availability isn't universal. California is the most notable example: the state doesn't recognize the PLLC structure for licensed professionals at all, and requires them to form a professional corporation or a limited liability partnership instead, depending on the profession. Before assuming a PLLC is available (or required), check directly with your state's Secretary of State and your profession's licensing board, since the requirement, the entity options, and the approval process all vary by state.

Can I just form a regular LLC instead of a PLLC?

Not if your state requires licensed professionals in your field to use a PLLC (or a professional corporation) instead. Filing the wrong entity type for a licensed profession can mean the state rejects the filing outright, so check with your state's Secretary of State or your licensing board before filing.

Does a PLLC protect me from my own malpractice?

No. A PLLC protects your personal assets from the business's general debts and from other members' malpractice, but not from a claim based on your own professional error — that liability follows you personally regardless of the entity structure.

Which professions typically need a PLLC?

It varies by state, but doctors, dentists, lawyers, accountants, architects, engineers, and therapists are the professions most commonly required or permitted to form one. Some states extend the requirement to additional licensed occupations, so confirm with your specific licensing board.

What happens if my state doesn't allow PLLCs?

You'll need a different entity type for a licensed practice — commonly a professional corporation (PC) or a limited liability partnership (LLP), depending on the state and profession. California is the most notable state that doesn't recognize PLLCs at all.
