PLLC vs. LLC: Key Differences

What a PLLC Is

A professional limited liability company (PLLC) is a version of the standard LLC that many states created specifically for licensed professions. It follows the same basic state filing process as a regular LLC, Articles of Organization and a registered agent, but adds licensing-specific requirements on top, such as proof that the members hold the required professional license.

Who Has to Use a PLLC Instead of a Regular LLC

In states that recognize PLLCs, licensed professionals, commonly including physicians, attorneys, accountants, architects, engineers, and similar licensed fields, are generally required to form a PLLC rather than a regular LLC if they want to practice that licensed profession through a limited liability entity. The exact list of professions required to use a PLLC is set by each state and by the relevant licensing board, so check both your state's LLC statute and your profession's specific licensing rules.

Ownership Restrictions Are the Main Legal Difference

A regular LLC has no ownership restrictions: anyone, licensed or not, can be a member. A PLLC, by contrast, generally requires every member to hold a current license in the profession the business practices, and some states also restrict who can serve as a manager. This matters if you're considering bringing in a business partner or investor who isn't licensed in your field; that person generally can't hold a direct ownership interest in a PLLC the way they could in a regular LLC.

A PLLC Doesn't Shield Professional Malpractice Liability

Both a PLLC and a regular LLC protect personal assets from the business's ordinary debts and from a co-owner's own wrongdoing. Neither one protects a licensed professional from liability for their own malpractice or professional negligence; that liability follows the individual regardless of which entity structure they practice through. This is the single most important thing to understand about a PLLC: it isn't extra malpractice protection, it's a licensing-compliant version of an LLC.

Formation Is Similar, With One Added Step: Proof of Licensure

Forming a PLLC generally follows the same Articles of Organization process as a regular LLC, filed with the same state filing agency, often using a PLLC-specific form. The added step is documentation: many states require a certificate or confirmation from the relevant licensing board verifying that the organizers or members hold a valid license before the state will approve the PLLC filing.

Nine States Don't Offer a Separate PLLC Entity

California, Delaware, Hawaii, Indiana, Louisiana, South Carolina, Vermont, Wisconsin, and Wyoming have no PLLC provision in their LLC statutes. In these states, licensed professionals typically either form a regular LLC, if their specific licensing statute permits it, or use a different entity altogether, such as a professional corporation or a registered limited liability partnership, depending on the profession and state rules.

Check Your Licensing Board, Not Just Your State's LLC Statute

Whether you need a PLLC, can use a regular LLC, or must use an entirely different entity depends on both your state's business entity statute and the rules your specific licensing board sets for that profession. These two sources don't always say the same thing, so confirm the requirement directly with your licensing board before filing.

A PLLC Still Needs Malpractice Insurance

Because neither a PLLC nor a regular LLC protects a professional from their own malpractice liability, carrying adequate professional liability (malpractice) insurance remains essential regardless of which entity you use. The entity structure and the insurance serve different purposes and neither substitutes for the other.

Multi-Disciplinary Practices Can Complicate PLLC Ownership

If your business involves professionals from more than one licensed field, such as a practice combining physicians and other licensed providers, check whether your state's PLLC rules allow mixed ownership across professions, since some states restrict a PLLC to a single type of license holder.

Talk to a Business Attorney Familiar With Your Profession

PLLC rules vary significantly by state and by profession, and getting the entity choice wrong can mean refiling, losing time, or even practicing under a non-compliant structure. This isn't legal advice; talk to a business attorney or your licensing board before choosing between a PLLC, a regular LLC, and other professional entity options available in your state.
