PLLC vs LLC — When Licensed Professionals Need a PLLC

If your profession requires a state license and your state mandates a professional entity for that license, you must form a PLLC (or in some states, a PC), not a standard LLC. A PLLC is functionally identical to an LLC for tax and liability purposes, with one hard rule: every member must be licensed in the profession the entity practices. Filing the wrong entity is a licensing-board problem, not a tax problem — and it does not fix itself quietly.

What a PLLC Actually Is

A Professional Limited Liability Company (PLLC) is a variant of the LLC created specifically for state-licensed professions. It exists because most state legislatures decided that licensed professionals — doctors, lawyers, CPAs, architects, engineers, and similar — should be able to form limited liability entities, but with two guardrails:

• Ownership restriction: Every member must be licensed in the profession the PLLC practices. A group of physicians can form a medical PLLC; a physician plus their spouse (who isn't licensed) cannot.
• Practice restriction: The PLLC can only render the licensed service and closely related services. A medical PLLC can't also run a restaurant.

Everything else — the state filing process, the operating agreement, the liability shield for non-malpractice claims, the tax elections — mirrors a standard LLC. If you're already familiar with how LLC formation works, PLLC formation adds one step: licensing-board sign-off.

Which States Require or Offer a PLLC

The rules vary widely. Here is the 50-state landscape:

New York deserves special mention. The New York Education Department has to sign off on every PLLC filing before the Department of State will accept the Articles of Organization. The approval process takes 4 to 12 weeks and requires certified license copies for every member. See our New York LLC formation guide for the full workflow.

Which Professions Typically Trigger the Rule

The professions most often subject to PLLC (or PC) requirements are:

• Attorneys and lawyers (nearly universal)
• Physicians, surgeons, and physician assistants
• Dentists, orthodontists, and dental hygienists
• Chiropractors
• Pharmacists
• Optometrists
• Psychologists, therapists, and licensed clinical social workers
• Certified Public Accountants (CPAs)
• Architects
• Professional engineers
• Land surveyors
• Veterinarians
• Licensed insurance agents (in some states)
• Real estate brokers (in some states)

Licensed insurance agents are a state-by-state coin flip. In roughly a dozen states, the agent's E&O carrier or the state Department of Insurance strongly prefers a PLLC even when it's not statutorily required. If you're an agent, our LLC for insurance agents guide breaks down which states apply and what the E&O carriers actually ask for.

What Happens If You Form the Wrong Entity

Three things can go wrong, and they often stack:

1. The state voids the entity. If a state that requires a PLLC discovers you filed an LLC, the Secretary of State can void the formation retroactively. Everything you did while operating under that entity — contracts, tax returns, bank accounts — is now on you personally.

2. The licensing board sanctions your license. Most licensing boards treat improper entity formation as unprofessional conduct. Sanctions range from a fine and public reprimand to license suspension. This is the worst outcome because it affects your ability to practice.

3. Personal liability exposure. If the entity is voided or ignored, plaintiffs can reach personal assets on all claims — not just malpractice — as if the LLC never existed.

The fix, if caught early, is usually to file a Certificate of Conversion or a new PLLC formation and to notify the licensing board voluntarily. Voluntary disclosure typically results in a lower sanction than a board discovery.

The Licensing-Board Approval Process

Most PLLC filings follow this sequence:

1. Draft Articles of Organization for a PLLC with the required professional-service language (each state has its own template — do not use a standard LLC template).
2. Get certified license copies for every intended member.
3. Submit Articles and license copies to the state licensing board (or the department that oversees the profession) for pre-approval.
4. Board issues a Certificate of Approval or endorses the Articles.
5. File the endorsed Articles with the Secretary of State along with the standard filing fee.
6. Wait for SoS approval, then apply for the EIN and open the bank account.

Timelines vary. Some states (Tennessee, Texas) process board approval in 2 to 3 weeks. New York averages 6 to 12 weeks. Plan formation timelines accordingly — this is not a same-day filing.

Tax Treatment

Federal tax treatment of a PLLC is identical to an LLC. Single-member = disregarded entity by default. Multi-member = partnership by default. Either can elect S-Corp treatment via Form 2553 or C-Corp via Form 8832. The IRS makes no distinction based on the "professional" label.

A handful of states have franchise-tax quirks for professional entities. California PCs pay an $800 minimum franchise tax same as LLCs. Texas PLLCs are subject to Texas franchise tax same as LLCs (but with the same $2.47M no-tax-due threshold). Tennessee levies both franchise and excise tax on PLLCs. Check your state before assuming parity.

Insurance Considerations — What a PLLC Does Not Do

Here is the most misunderstood part of forming a PLLC: it does not shield you from your own malpractice. If you are a physician and a patient sues you for medical malpractice, the plaintiff can reach your personal assets regardless of whether you operated as a PLLC, PC, or sole practitioner. The malpractice liability follows the license, not the entity.

What a PLLC does shield you from is other members' malpractice, general commercial liability (a slip-and-fall in the office), employee claims, and vendor lawsuits. Which is meaningful — but it means every PLLC still needs professional liability (E&O or malpractice) insurance sized appropriately for the practice.

PLLC Formation Timeline — What to Expect

A standard LLC in most states goes from filing to state approval in 1 to 2 weeks. A PLLC adds a licensing-board approval step at the front, which is why realistic total timelines look like this:

Plan accordingly. If you have a client engagement letter or a lease that requires a signed entity name, work backward from the target date and build in board approval time. Do not sign contracts under a PLLC name that has not been approved yet — you may end up personally liable for anything you sign as an unformed entity.

Cost Breakdown for a PLLC vs a Standard LLC

PLLCs cost a bit more to form because of the board approval and license verification steps. Rough national ranges:

• Standard LLC: $50 to $500 in state filing fees, no board involvement.
• PLLC: Same state filing fee plus $0 to $250 in licensing-board application fees, plus certified license copy fees ($10 to $50 each).
• New York PLLC: Add the publication requirement (~$800 to $2,000 in NYC counties) and the Education Department review fee ($90 per member).

Ongoing compliance costs are nearly identical to a standard LLC. Some states charge slightly higher annual report fees for professional entities; most do not.

Frequently Asked Questions

Do I need a PLLC or an LLC?

If you hold a state professional license and your state offers or requires PLLC for your profession, form the PLLC. If your state doesn't offer PLLC (Ohio, Oregon, Massachusetts, Wisconsin, Indiana), form a standard LLC or PC depending on what your state and licensing board allow.

Can a PLLC have non-licensed owners?

Generally no. Every state that requires PLLC also requires every member to be licensed in the profession the PLLC practices. Passive investors, spouses, and children cannot own equity unless they hold the license too.

Can I have an LLC that owns my PLLC?

Almost never. Ownership restrictions bar most holding-company structures for PLLCs. A few states permit a licensed-professional-owned LLC to hold a PLLC, but it's rare and requires state-specific research.

How is a PLLC taxed differently from an LLC?

Federally, it isn't. Same default treatment, same S-Corp and C-Corp election options. Some states apply small franchise-tax variations, but the difference is usually less than $200 per year.

Do I need a PLLC if I'm a solo practitioner?

Yes, in states where PLLC is required. Solo status does not exempt you. The licensing board still expects a professional entity if the state statute requires one.

What's the difference between a PLLC and a PC?

PC (Professional Corporation) is the corporate equivalent — filed under the state's corporation statute, taxed by default as a C-Corp, with shareholders instead of members. PLLC is filed under the state's LLC statute with pass-through default taxation. Some states (California, Ohio) only allow PC for licensed professions; most others allow both.

Does my licensing board have to approve amendments to my PLLC?

Often, yes. Adding or removing members, changing the practice scope, or dissolving usually requires board notice or approval. Read your state's statute or ask the board directly.
