A Professional LLC (PLLC) is a special LLC for licensed professionals. It protects you from business liabilities and other members’ malpractice, but not from your own professional negligence.

Quick answer: If you’re a licensed professional (doctor, lawyer, CPA, architect, etc.), many states require you to form a PLLC instead of a regular LLC. It works like a regular LLC with one key difference: you’re still personally liable for your own malpractice. Formation is the same process ($40–$500) with the addition of a state licensing board approval.

Tax Considerations

PLLCs are taxed identically to regular LLCs:

1 member Disregarded entity (Schedule C) S-Corp election
2+ members Partnership (Form 1065) S-Corp or C-Corp election

Common Tax Structures for Professional PLLCs

Practice Size Common Structure
Solo practitioner PLLC with S-Corp election
2–5 partners Multi-member PLLC (partnership or S-Corp)
Large group practice PLLC or PC with S-Corp or C-Corp election

Operating Agreement Additions for PLLCs

Beyond standard operating agreement provisions, PLLCs should address:

Provision Why It Matters
License maintenance Members must maintain active licenses
What happens if license revoked Buyout trigger, forced withdrawal
Malpractice insurance requirements Minimum coverage amounts for all members
Professional standards Adherence to professional ethics codes
Supervision requirements Who supervises employees/residents
Peer review process Internal quality assurance
Non-compete clause Post-departure restrictions on practice
Client/patient transition How clients/patients are handled when a member leaves

PLLC vs. PC (Professional Corporation)

Feature PLLC PC
Entity type LLC Corporation
Formation flexibility More flexible More rigid
Tax default Partnership (multi-member) C-Corp
Ongoing formalities Less formal Board meetings, minutes, bylaws required
Malpractice protection Same Same
States available Many but not all Available in all states
Common for Small practices, modern preference Traditional medical/law practices

Common Mistakes

Mistake Consequence
Forming regular LLC instead of PLLC State may not recognize it; licensing issues
Not all members licensed Formation may be rejected
Thinking PLLC covers your own malpractice It doesn’t — personal liability remains
Skipping malpractice insurance PLLC protects against business debts, not professional negligence
Not addressing license revocation in operating agreement No clear process if a member loses their license
Practicing in another state under home-state PLLC May need foreign PLLC registration + out-of-state license

Bottom Line

A PLLC is simply an LLC with professional licensing requirements layered on top. It protects you from business debts and other members’ malpractice, but not from your own professional negligence. Malpractice insurance remains essential. If your state requires a PLLC for your profession, formation is nearly identical to a regular LLC with the addition of licensing board approval. If your state uses PCs instead (like California), form a Professional Corporation.
