Share This Post

A Professional Limited Liability Company (PLLC) is a business structure tailored for licensed professionals like doctors, lawyers, and architects. It combines liability protection for personal assets with the ability to operate a professional practice. Unlike standard LLCs, PLLCs are restricted to individuals holding professional licenses. Here’s what you need to know:

  • Liability Protection: Shields personal assets from business debts but does not cover malpractice or professional negligence.
  • Membership Rules: Limited to licensed professionals, often requiring the same type of license among members.
  • Tax Benefits: Treated as pass-through entities, avoiding double taxation.
  • State-Specific Regulations: Only 29 states and D.C. allow PLLCs; others require alternative structures like professional corporations.
  • Formation Process: Includes licensing board approval, naming restrictions, and compliance with state laws.

PLLCs are ideal for professionals seeking asset protection while maintaining personal accountability for their work. Always check your state’s specific regulations and consult with a business attorney before forming one.

How PLLCs Differ from Standard LLCs

While PLLCs and standard LLCs share some structural traits, they follow distinct rules tailored to the regulated nature of professional services. These differences highlight how PLLCs are specifically designed to meet the needs of licensed professionals.

Membership Requirements

The biggest distinction between PLLCs and standard LLCs lies in who is allowed to own and operate them. Standard LLCs are open to a wide range of members – individuals, corporations, partnerships, or other business entities can all form or join one. This flexibility makes standard LLCs appealing to entrepreneurs across various industries.

PLLCs, on the other hand, have much stricter rules. Membership is typically limited to licensed professionals, and in many states, all members must hold the same type of professional license. For instance, a PLLC created by attorneys cannot include engineers or accountants as members, even if they are licensed professionals in their respective fields.

Additionally, members must maintain active and valid licenses to remain part of the PLLC. If a member’s license expires, is suspended, or is revoked, they may be required to leave the PLLC or transfer their ownership interest to another licensed professional. These rules ensure compliance with state regulations and hold members accountable to their licensing boards.

Liability Protection

Both PLLCs and standard LLCs offer liability protection, but the nature of this protection varies. Standard LLCs generally shield members from personal liability for business debts and obligations, keeping personal and business assets separate.

PLLCs provide a more specific type of liability protection. Members are protected from liability stemming from another member’s professional misconduct or negligence, but they remain fully accountable for their own professional actions. For example, if one attorney in a law firm PLLC commits malpractice, the other attorneys are typically shielded from related claims. However, if you personally commit malpractice or professional negligence, you are directly responsible for those actions.

This distinction reinforces individual accountability within the PLLC structure. While members may be protected from certain business debts or contractual obligations, professional liability insurance is often required, and licensing boards can still impose disciplinary actions regardless of the PLLC’s structure.

Operational Limitations

Standard LLCs enjoy broad operational freedom. They can engage in nearly any legal business activity, pivot between industries, and adapt their business models as needed. This makes them suitable for ventures ranging from real estate to retail.

PLLCs, however, operate under stricter constraints. These entities are limited to providing services directly related to the profession of their licensed members. For example, a PLLC formed by dentists can only offer dental services and related activities. Expanding into unrelated areas, like running a restaurant or retail store, could violate state regulations governing PLLCs.

Operational restrictions also apply to decision-making authority. In many states, only licensed members are permitted to make decisions about the professional services the PLLC provides. While non-licensed staff can handle administrative tasks, the licensed members retain control over professional judgment and service delivery.

These limitations ensure that professional services remain aligned with ethical standards and regulatory oversight. Although this reduces business flexibility, it gives clients confidence that services are being provided by qualified and accountable professionals, maintaining the integrity of regulated professions.

Professions That Need a PLLC

Understanding the need for a PLLC often comes down to state-specific regulations for licensed professionals. While the exact requirements differ across the United States, there are some clear patterns when it comes to which professions benefit from or are required to use this business structure.

Common Professions That Require a PLLC

The PLLC model is particularly suited for licensed professionals who provide services directly to the public. In many states, professionals in fields such as law, medicine, dentistry, accounting, architecture, engineering, chiropractic care, and mental health are required to operate as PLLCs to comply with state regulations. These professions are often closely monitored by state licensing boards, which enforce strict standards for practice and liability.

"PLLCs can only offer services related to its profession (as opposed to the LLC, which can transact in any business it wishes, as long as it is legal, of course). The only people that can have ownership in a PLLC are those that can provide the services that require the license." – Charlton M. Messer, Attorney at Messer Law Firm, PLLC

Healthcare professionals, including optometrists, podiatrists, physical therapists, and veterinarians, often form PLLCs, especially in group practice settings. This structure helps balance shared liability protection with individual accountability. Similarly, law firms frequently use PLLCs to shield members from liability tied to another attorney’s malpractice. Accounting firms also adopt this model to protect partners from errors made by others within the firm. In design and construction, architects, engineers, and surveyors rely on PLLCs to manage liability risks associated with project-based work.

State-Specific Variations

Although many professions share similar needs for PLLCs, state regulations can differ dramatically. Some states do not even allow PLLC formation, requiring professionals to choose other structures like professional corporations or standard LLCs instead.

For example, Illinois has strict ownership rules. In this state, only a licensed physician can own a PLLC for a medical practice. This means a physician cannot co-own the business with a spouse who manages the practice unless the spouse is also licensed. However, a physician can co-own a PLLC with a podiatrist, but not with a registered nurse.

In Idaho, the rules are more specific. The state permits PLLCs for a defined list of professions, including architecture, accounting, chiropractic care, dentistry, engineering, landscape architecture, law, medicine, nursing, occupational therapy, optometry, physical therapy, podiatry, geology, psychology, social work, surveying, and veterinary medicine.

Even less obvious professions, like real estate brokers, may be required to operate under a PLLC in certain states. These state-specific variations highlight the importance of understanding local rules before establishing a PLLC.

Checking Professional Board Requirements

To navigate these complexities, it’s crucial to consult your state’s licensing board. These boards typically provide detailed guidance on approved business structures and may even offer consultation services to clarify the rules. Additionally, seeking advice from a local business attorney who specializes in professional services can help ensure compliance and avoid costly mistakes. Knowing these requirements is an essential step before moving forward with forming your PLLC.

Creating a Professional Limited Liability Company (PLLC) involves additional steps compared to forming a standard LLC. These extra steps are tied to professional licensing and ensuring compliance with state-specific regulations, which vary depending on your profession and location.

Licensing and Verification

To form a PLLC, every member and manager must have an active professional license in the specific field where the PLLC will operate. The state licensing board must verify these credentials and approve the PLLC’s articles of organization before moving forward. This process starts by submitting proof of licensure to the board, which may require approval before you can proceed.

Keep in mind that each state maintains a list of professions eligible for PLLC formation. To avoid delays, contact your state’s licensing authority to confirm that your profession qualifies. In some cases, the licensing board may ask for additional documentation to ensure all members meet professional standards.

Naming Rules for PLLCs

The name of your PLLC must meet strict naming conventions, which are regulated at the state level. Most states require the name to include the phrase “Professional Limited Liability Company” or an abbreviation such as “PLLC” or “P.L.L.C.” Additionally, the name must be unique and distinguishable from other registered entities.

Before deciding on a name, conduct a thorough search through your state’s business registry to confirm its availability. Be aware that professional licensing boards may impose additional restrictions, especially if the name could be misleading or imply services that are not authorized.

Step-by-Step Formation Process

Once you’ve met the licensing and naming requirements, follow these steps to form your PLLC:

  • Obtain Regulatory Board Approval: Before filing any official documents, secure approval from the regulatory board overseeing your profession. This step is required before proceeding with state filings.
  • Secure Your Business Name: After obtaining board approval, confirm your name complies with state regulations. Ensure it includes “Professional Limited Liability Company” or an approved abbreviation.
  • Designate a Registered Agent: Choose a registered agent to handle legal documents and official correspondence on behalf of your PLLC. The agent must have a physical address in the state where your PLLC is being formed and be available during standard business hours.
  • File Articles of Organization: Submit your articles of organization to the Secretary of State. These documents will also be reviewed by your profession’s licensing board, which may extend processing times compared to forming a standard LLC.
  • Draft an Operating Agreement: Create an operating agreement that defines the roles of each member, outlines operational rules, and specifies how profits and losses will be divided. Consulting a business attorney for this step is highly recommended.
  • Apply for a Federal Tax ID: Obtain an Employer Identification Number (EIN) from the IRS. This is essential for tax reporting and opening business bank accounts.
  • Choose a Tax Classification: Decide whether your PLLC will be taxed as a pass-through entity, an S corporation, or a C corporation. This choice will impact how your income is taxed.
  • Meet Additional Compliance Requirements: Depending on your state, there may be extra regulatory steps to follow at both the state and federal levels.

Some states add unique procedural steps that can complicate the process. For instance, certain jurisdictions may require you to prepare a certificate of incorporation, submit it to the State Education Department for license verification, file it with the Secretary of State, and then return a certified copy to the Education Department.

Once your PLLC is officially formed, it’s important to maintain its legal status by keeping personal and business finances separate and ensuring that all professional licenses remain up to date.

PLLC Pros and Cons

Choosing a PLLC requires a careful look at its benefits and limitations. While a PLLC can provide a helpful layer of protection by separating personal assets from business liabilities, it also introduces specific restrictions and complexities that aren’t typically found with standard LLCs.

Advantages of a PLLC

Personal Asset Protection
One of the standout benefits of a PLLC is its ability to protect personal assets – like your home, savings, or investments – from business-related debts. This separation can be vital for professionals looking to safeguard their personal finances.

Disadvantages of a PLLC

No Malpractice Protection
Although a PLLC protects personal assets from business debts, it does not shield you from liability for professional errors or malpractice. You remain personally accountable for your professional conduct.

Complex Formation Process
Setting up a PLLC involves additional steps compared to a standard LLC. You’ll need approval from a regulatory board, verification of professional licenses, and compliance with extra regulations – all of which increase both the complexity and cost of formation.

Restricted Membership
Membership in a PLLC is limited to licensed professionals, which can restrict your ability to bring on partners or investors who don’t hold the required licenses.

Limited State Recognition
As of 2025, only 32 states recognize PLLCs. Expanding your business into states without PLLC recognition may require a complete restructuring of your business model.

Taxation Complications
While PLLCs are treated as pass-through entities for tax purposes, they can create challenges, such as triggering taxes on unrealized gains due to immediate profit recognition.

Lending Challenges
Some lenders view PLLCs with added scrutiny, which could make securing business loans more difficult than it would be for other types of business structures.

Before committing to a PLLC, it’s wise to consult with legal and tax professionals. They can help you determine whether this structure aligns with your business needs and complies with the regulatory demands of your profession.

Pros and Cons Comparison Table

Aspect Advantages Disadvantages
Liability Protection Shields personal assets from business debts No protection against personal liability for professional malpractice
Formation Process Provides a structure for licensed professionals More complex and costly due to licensing and compliance
Membership Restricted to licensed professionals, limiting partnerships and investments
State Recognition Recognized in only 32 states as of 2025, complicating geographic expansion
Taxation Operates as a pass-through entity May face issues like taxes on unrealized gains due to immediate profit recognition
Lending May encounter stricter scrutiny from lenders, making loans harder to obtain

Weigh these factors carefully to make an informed decision about whether a PLLC is the right fit for your professional services. Each of these considerations plays a critical role in determining the best business structure for your practice.

Is a PLLC Right for Your Professional Practice?

Choosing whether a PLLC suits your professional practice involves more than just liability protection. It requires a close look at state regulations, your profession’s specific needs, and how this structure fits into your overall business goals. Let’s explore some key factors to help you decide.

State Recognition and Geographic Limitations

One crucial consideration is whether your state recognizes PLLCs. As of 2025, only 32 states allow this structure. For instance, California does not permit PLLCs, leaving professionals to choose between registered limited liability partnerships (LLPs) or professional corporations (PCs) instead.

Professional Licensing Requirements

Another important factor is licensing. Many states restrict PLLC ownership to individuals with specific professional credentials. This can limit your ability to bring in partners or investors who lack the required qualifications, potentially affecting your business’s growth and partnership opportunities.

Liability Protection Considerations

While PLLCs offer liability protection, it’s important to remember that this doesn’t cover personal professional errors. Additionally, some states mandate that PLLC members carry professional liability insurance with minimum coverage amounts.

Business Structure Alternatives

If a PLLC doesn’t align with your needs, other options like Professional Corporations (PCs) and Limited Liability Partnerships (LLPs) might be worth exploring. Each comes with its own tax implications and management requirements, so it’s essential to weigh these alternatives carefully.

Forming a PLLC often involves more steps than setting up a standard LLC. This process typically requires approval from your state licensing board and ongoing compliance with professional regulations. For example, in New York, practicing a licensed profession through any entity other than those approved by the state is considered a criminal Class E felony.

To navigate these complexities, consult with a business attorney and a CPA. They can provide tailored guidance, and you should also reach out to your state bar association or regulatory agency to ensure you meet all jurisdictional and professional requirements.

FAQs

What’s the difference between a Professional LLC (PLLC) and a Professional Corporation (PC), and how do I choose the right one for my practice?

Key Differences Between a Professional LLC (PLLC) and a Professional Corporation (PC)

When comparing a Professional LLC (PLLC) to a Professional Corporation (PC), the main distinctions lie in their structure, taxation, and liability protections.

A PLLC is a type of limited liability company specifically designed for licensed professionals. It offers pass-through taxation, meaning profits and losses are reported on the members’ personal tax returns, avoiding corporate-level taxes. While members enjoy limited liability for business debts, they are still personally responsible for malpractice or professional negligence.

On the other hand, a PC operates as a corporation, providing liability protection for business obligations and debts. However, unless it qualifies for S-corporation status, a PC may face double taxation, where both the corporation and its shareholders are taxed on earnings.

Which Option is Right for You?

Choosing between a PLLC and a PC depends on several factors, including your tax strategy, liability priorities, and state regulations. A PLLC often suits professionals who prefer flexible management and straightforward taxation. Meanwhile, a PC might appeal to those who value a corporate structure and enhanced liability protection for business matters.

To make the best decision, it’s wise to consult with a legal or tax professional who can assess your specific situation and guide you accordingly.

Can a PLLC have members with different professional licenses, and what happens if a member loses their license?

In many states, a Professional Limited Liability Company (PLLC) must ensure that all its members hold valid licenses in the same profession the business serves. This rule helps the PLLC stay aligned with industry regulations, which is particularly crucial for fields like law, medicine, or accounting.

If a member’s professional license is revoked or expires, it can lead to serious complications. State laws often dictate that unlicensed individuals cannot remain members of a PLLC, which might force the company to restructure or, in some cases, dissolve entirely. To avoid such disruptions, it’s wise to carefully review your state’s regulations and include clear guidelines in your operating agreement to handle these scenarios.

What can I do to protect my personal assets if my state doesn’t allow PLLCs?

If your state doesn’t allow the formation of Professional LLCs (PLLCs), you can still shield your personal assets by setting up a regular LLC and fulfilling your profession’s licensing requirements. This often involves securing malpractice insurance, complying with state-specific rules, and following the ethical and legal standards expected in your field.

To enhance your protection, it’s critical to adopt sound business practices. This includes keeping personal and business finances separate, maintaining thorough records, and seeking advice from a qualified attorney to ensure you’re meeting all state regulations. These measures can help safeguard your professional practice, even if a PLLC isn’t an option.
