PLLC vs LLC: how clinicians choose and maintain a practice entity

PLLC vs LLC: what the difference is

An LLC is a state-law entity that can elect among several tax treatments and that may provide liability separation, subject to the governing law, how the entity is maintained, any personal guarantees, and the type of claim. It is flexible, which is why it's a common starting point for small practices and side ventures.

A PLLC is the professional version. Many states require licensed healthcare professionals to practice through a professional entity, a professional corporation or a PLLC, so that licensed professionals remain in control of healthcare practices. Requirements differ by state and by license type, including which entity forms a licensed practice may use at all.

So before forming anything, verify your state's requirements for your specific license type with a healthcare attorney. It is usually one conversation.

The four structures a practice can start from

Four structures, each built for a different situation:

• Sole proprietorship: no formation step, no filings to create it, and no entity standing between the individual and the business obligations. Whether it suits a given activity depends on your state's rules for the license type, the liability profile and the practice's own facts.
• Limited liability company: a state-law entity that can elect among several tax treatments and may provide liability separation, subject to the governing law, maintenance, personal guarantees and the type of claim. Many states require licensed healthcare professionals to use the professional version, the PLLC, or a professional corporation.
• S-corporation: an election that splits owner income between salary and distributions, and brings payroll filings and a reasonable-compensation requirement with it. More moving parts, more compliance work, and the right answer only for some practices.
• C-corporation: a separate taxpayer with its own return and its own rules. Uncommon for clinical practices, but a term worth recognizing.

What a PLLC can and can't protect

An appropriately formed and maintained professional entity may limit some business liabilities: contracts, business debts, premises claims, and claims arising from the conduct of others in the practice. That limitation is subject to personal guarantees, veil-piercing doctrines, the governing law of the jurisdiction, and the nature of the claim.

What it does not do is address your own professional negligence. Every clinician remains personally responsible for their own clinical care. That is what professional liability coverage is for, and no entity changes it. The structure and the coverage are partners, not substitutes.

Picture a physical therapist who runs a small outpatient practice as a PLLC. A landlord dispute over premises damage turns into litigation against the practice. Because he kept separate accounts, documented decisions, adequate capitalization and contracts signed in the practice's name, the entity holds up, and the business obligations stay with the practice. Had it been a malpractice claim, no entity would have shielded him. For the business dispute it was built for, the structure did its job.

What the structure obligates

Tax treatment shows up as one more set of obligations: each structure carries a different set of filings and deadlines. Which combination fits a specific practice is a question for a qualified accountant working from actual numbers.

Day to day, the obligations fall into five categories, and each one is a calendar item with a name on it:

• Formation and registration: the entity filed in the right state, in the form the licensing board permits, with any professional registration the board itself requires.
• Annual maintenance: the state's periodic report and fee, the registered agent, and any renewals.
• Payroll: once there is an employee, including an owner taking a salary, registrations, withholding, remittance and information returns follow prescribed deadlines.
• Documentation: where owner compensation splits between salary and distributions, the salary has to be supportable, and support means written evidence created at the time.
• The books: separate accounts, contracts in the entity's name, and records organized well enough to show all of the above.

Keeping the liability separation standing

Liability separation is not automatic; it's maintained. Common governance practices all point the same direction: separate business bank accounts, adequate capitalization, documented decisions and meeting minutes, contracts signed in the entity's name and never the individual's, and appropriate business coverage. Which of these your entity form and state actually require is a short question for local counsel.

The conduct that can weaken the separation, the kind that comes up when a court is asked to pierce the veil: commingling personal and business funds, paying personal expenses from the business account, skipping the formalities, underfunding the entity, and fraud. The question at the center of the doctrine is whether the entity was treated as genuinely separate from its owner. How that test is applied varies by jurisdiction.

The ongoing time and fees vary by state, entity form, ownership, payroll and governance requirements, so work out your own maintenance burden before formation, not after.

When to revisit the structure

Structures should change when circumstances do. Four triggers, none of them a number:

• Add an entity when a distinct business line or consulting practice begins, when there are employees, or when business obligations belong separated from the individual.
• Convert or make a new election when profit, owner compensation, payroll and administrative capacity have all changed enough that the current form no longer matches the operation. There is no universal trigger point; it is an accountant's analysis of a specific practice.
• Evaluate separate ownership, with counsel and the accountant, where real estate is involved or where business lines carry materially different risk and regulatory profiles.
• Simplify when the administrative burden exceeds the benefit, a business line winds down, or consolidation makes operational sense.

A one-month entity check

Five steps:

• Identify the current structure, or acknowledge there isn't one.
• Gather the governance file: formation documents, state filings, registered agent and the last annual report.
• Confirm every contract and account is in the entity's name.
• Verify your state's professional-entity requirements for your license type.
• Schedule two consultations: an accountant who works with clinical practices, and a healthcare attorney.
