If you’re starting a business in a licensed profession (law, medicine, engineering, accounting, architecture, etc.), you’ve probably run into the terms LLC and PLLC and wondered what the real difference is. This guide explains the difference between LLC and PLLC and compares PLLC vs LLC, for people who need to make the right choice for both legal compliance and practical business reasons.
What is an LLC?
An LLC is a state-level business entity that blends features of partnerships and corporations. Owners (called members) enjoy limited personal liability for business debts and judgments, meaning personal assets are generally shielded from business creditors. LLCs are popular because they allow flexible management structures and simple pass-through taxation (income taxed on owners’ personal returns unless the LLC elects corporate taxation).
Key practical features:
- Easy to form (file articles of organisation with the state).
- Owners can be individuals, other companies, or even foreign entities.
- Personal asset protection for most business liabilities (but not for the owners’ own professional malpractice).
What is a PLLC?
A PLLC is essentially an LLC for licensed professionals. States use varying labels—PLLC, Professional LLC, Professional Limited Liability Company, or Professional Service LLC—but the concept is the same: the entity is designed for occupations that require state licensure (doctors, lawyers, accountants, architects, engineers, many types of health practitioners). In many states, only members who hold the required professional license may be members of the PLLC.
Typical PLLC features that distinguish it from a plain LLC:
- Membership restrictions: Members must be licensed in the profession that the PLLC will provide.
- Licensing board oversight: The formation documents often require verification of professional licenses and, in some jurisdictions, approval from the relevant licensing board.
- Naming rules: Many states require the entity name to include language like “PLLC” or “Professional Limited Liability Company.”
Core legal differences (side-by-side)
Who can form it
- LLC: Almost any person or entity (subject to state rules).
- PLLC: Restricted to licensed professionals; states typically require license checks.
Liability for malpractice
- LLC/PLLC: Both provide limited liability for many business debts, but no entity shields a professional from personal responsibility for their own malpractice. In a PLLC, a member remains personally liable for their own professional negligence; however, other members are usually shielded from another member’s malpractice (subject to state law).
State recognition and mandatory use
- Some states force licensed professionals to form professional entities (PC/PLLC/PA) instead of ordinary LLCs; other states let professionals choose. Rules vary by state. Always check the state secretary of state and licensing board.
Governance, taxation, and filing
- Both entities are governed by state LLC statutes and follow similar filing procedures (articles of organisation, operating agreement), and both normally allow pass-through taxation. Differences mostly come from licensing and member eligibility rules.
Why does the distinction matter? (Practical implications)
- Compliance: Forming the wrong entity can violate state licensing rules and invite enforcement action from professional boards. If your profession is regulated in your state, forming a non-professional LLC when the state requires a PLLC/PC can be a costly mistake.
- Liability clarity: PLLCs provide a clearer separation among professionals for malpractice claims. For example, if Dr A in a PLLC is sued for malpractice, Dr B’s personal assets may be insulated, subject to state specifics. That separation reduces cross-exposure among professionals in the same firm.
- Lender and client expectations: Clients, insurers and lenders in professional fields often understand and expect the PLLC/PC form and may request entity documents or proof of licensing. A properly structured PLLC can simplify malpractice insurance and client contracting.
Choosing between PLLC vs LLC — decision checklist
Use this checklist when deciding between PLLC vs LLC:
- Is your profession licensed in your state? (If yes, check whether the state requires a professional entity.)
- Are all potential owners licensed practitioners? If not, a PLLC might be impossible.
- Do you want the malpractice-segregation benefits a PLLC provides among members?
- Have you confirmed naming, filing, and licensing board requirements with your Secretary of State and the professional licensing board?
If in doubt, check your state’s guidance pages and consult a business attorney who understands professional entity rules in your jurisdiction.
How to form a PLLC
The exact process varies by state, but the steps commonly include:
- Confirm eligibility — Verify that your profession and the license(s) you hold meet the state’s definition of permitted professional services.
- Choose a name — Make sure the name meets state rules and usually includes “PLLC” or similar.
- File formation documents — Submit articles of organisation (or equivalent) and any professional affidavit or license verification to the Secretary of State. Some states require the licensing board’s approval.
- Create an operating agreement — Spell out management, membership, capital contributions, and how professional liability matters will be handled.
- Maintain licensure and insurance — Members must maintain active professional licenses and often professional liability insurance (malpractice).
Common misconceptions
- “A PLLC protects me from malpractice.” Wrong. No corporate form insulates a professional from responsibility for their own malpractice. PLLCs typically limit other members’ exposure to a colleague’s malpractice, but the practitioner who committed malpractice remains personally liable.
- “PLLCs are taxed differently from LLCs.” Not inherently. Taxation follows federal tax rules for LLCs (pass-through by default), unless the entity elects corporate taxation. The tax treatment of a PLLC is generally the same as that of an LLC. Differences are primarily in licensure and governance.
- “Every state uses PLLC.” No. State law varies—some states don’t use the PLLC label, some require PCs, and others allow professionals to form ordinary LLCs. Check your state.
Example: state variability
States differ in how they treat professional entities. For instance:
- Washington State offers guidance specifically distinguishing LLCs and PLLCs and outlines statutory references.
- Texas publishes charts showing which professions can use which entity types (LLC, PC, PLLC, etc.).
- Michigan, Virginia, Utah each have pages describing professional LLC/PLLC rules and filing requirements.
Because of these differences, a formation strategy that works in one state may be noncompliant in another.
When should you talk to a lawyer?
If you are a licensed professional forming a business entity, consult a lawyer when:
- You’re unsure whether your state requires a PLLC or permits a standard LLC.
- You plan to include non-licensed investors as owners (that’s often prohibited in PLLCs).
- You want to understand how malpractice exposure will be allocated among members and what insurance is required.
A qualified attorney will confirm state rules, draft the operating agreement to address professional liability issues, and coordinate any licensing board approvals.
Final takeaways
- The difference between LLC and PLLC boils down to who may own the entity and how professional licensure rules interact with entity formation.
- For licensed professions, PLLC vs LLC is often not a choice—state law may mandate a professional entity form.
- Always verify your state’s rules and consult an attorney before forming an entity for a regulated professional practice.
