If you're a doctor, lawyer, CPA, architect, therapist, or engineer, your state may require you to form a PLLC instead of a plain LLC. The difference matters — and getting it wrong can put your license at risk.
What a PLLC is
A Professional Limited Liability Company (PLLC) is a variation of the LLC designed for licensed professionals. The legal structure works like an LLC — limited liability, pass-through taxes, minimal formalities — with one critical rule: only licensed professionals can be members, and everyone must hold the relevant license.
Some states require a PLLC for licensed professionals; others let them form a regular LLC; a few don't recognize PLLCs at all and use a Professional Corporation (PC) instead. The rule is set by each state's licensing board.
Who needs one
Typically licensed professionals whose work requires a license to practice:
- Doctors, dentists, and nurses.
- Lawyers.
- CPAs and tax preparers.
- Architects and engineers.
- Therapists, counselors, and social workers.
- Pharmacists and veterinarians.
- Insurance agents and other licensed advisors.
The exact list varies by state. If your occupation requires a state license to practice, check your state's rules before forming.
How it's different from a regular LLC
| Regular LLC | PLLC | |
|---|---|---|
| Members | Anyone | Only licensed professionals |
| Liability | Limited | Limited — but NOT for malpractice |
| Who must be licensed | No | All members |
| State approval | Standard filing | Often requires board review |
| Name designator | "LLC" | "PLLC" (in most states) |
The biggest practical difference: malpractice liability. A PLLC shields your personal assets from *business* debts and general claims — but it does not shield you from professional malpractice. You can't structure your way out of your own professional errors; that's what malpractice insurance is for.
How to form one
- Check your state's rules — required designator, license requirements, and whether board approval is needed.
- Pick a name ending in the right designator ("PLLC", "Professional LLC", etc.).
- Confirm every member's license — most states require you to list licensed members and their license numbers.
- File the formation documents with the state — often with an additional professional board review step.
- Keep licenses current — a member who loses their license can trigger complications with the entity.
If members work in different fields
Some states allow multi-profession PLLCs (a doctor and a therapist together); others restrict each PLLC to a single profession. If you're forming with partners from different licensed fields, check whether your state permits it.
Tax treatment
PLLCs are taxed the same as regular LLCs:
- Single-member PLLC — disregarded entity, reported on the owner's Schedule C.
- Multi-member PLLC — taxed as a partnership (Form 1065).
- Electing S-Corp status — possible, subject to the same eligibility rules (and the same visa restrictions on shareholders).
Liability protection and malpractice insurance
The practical layer cake for a licensed professional:
- The PLLC — shields personal assets from business debts and general claims.
- Malpractice insurance — covers your own professional errors (the thing the PLLC can't).
- State licensing compliance — keeps you authorized to practice at all.
All three are needed; none replaces another.
Common questions
Can I convert my existing LLC to a PLLC? Often yes, but it depends on your state — some allow conversion, some require a new filing. Talk to your state's filing office (and ideally a professional) before acting.
Do I need a PLLC if I'm a solo practitioner? If your state requires a PLLC for your profession, yes — even solo. If your state allows a regular LLC, either structure can work; the PLLC signals professionalism and matches licensing rules.
Can a PLLC have non-licensed members? Usually no — all members must hold the relevant license. Passive, non-licensed investors are generally not permitted (some states make exceptions; check yours).
Is a PLLC the same as a PC? No — a PC (Professional Corporation) is a corporation structure with directors and shares. Your state may offer one, the other, or both for professionals.
