PLLC vs LLC: What Every Professional Needs To Know

Are you a licensed physician, CPA, or attorney looking to set up your own practice? An LLC looks like the obvious choice until you find out your state requires a specific entity structure for licensed professionals, or until you realize that your personal assets remain exposed for any malpractice claims arising from your own professional acts, regardless of how the entity is structured.

The biggest practical difference between PLLC and LLC comes down to who can own one and where it's available. A PLLC is restricted to licensed professionals in states that recognize the structure, requires all members to hold an active license in the relevant field, and, in many states, mandates carrying malpractice insurance as a condition of formation.

A standard LLC has none of those constraints. The choice is often made for you before you file anything. If your state doesn't recognize a PLLC for your profession, you are already looking at a professional corporation or registered limited liability partnership instead.

In this article, we break down how each entity works, where the liability protection actually holds, what each one costs to maintain, and which one fits your situation.

In brief:

• A PLLC is an LLC variant restricted to licensed professionals; several states, including California, don't recognize PLLCs at all.
• PLLCs protect members from malpractice claims arising from fellow members' acts, but not from their own professional errors; each member remains personally liable for malpractice they directly commit.
• LLCs are available in all 50 states with no professional licensing requirements; PLLCs are only available in states that recognize the structure for your specific profession.
• Both structures use pass-through taxation by default and can elect S-Corp treatment through IRS Form 2553.
• PLLC membership is restricted to licensed professionals in the relevant field; LLC ownership is open to anyone.

What are the main differences between PLLC and LLC?

The biggest practical difference between a PLLC and an LLC comes down to what each structure protects against, and where it's available. Ownership restrictions are often the deciding factor before malpractice protection even enters the picture. If your state doesn't recognize PLLCs for your profession, the decision is already made for you.

Here are the key differences at a glance:

Let’s dive deep into how each entity actually works so you can confirm which one applies to your situation before you file.

A deep dive into Professional Limited Liability Companies for licensed practice founders

A PLLC (Professional Limited Liability Company) is a type of LLC designed specifically for licensed professionals such as physicians, attorneys, CPAs, architects, and engineers.

It offers the same pass-through taxation and basic liability protection as a standard LLC, with one critical carve-out: a PLLC does not protect a member from malpractice claims arising from their own professional acts.

Each member remains personally liable for errors they commit directly, even when the entity shields them from co-members' malpractice. If you commit malpractice, your personal assets remain exposed, regardless of the entity's structure. The PLLC protects your assets from a partner's errors, not from your own.

That restriction also shapes who can join. A PLLC organized to provide a specific licensed service requires that all (or, in some states, a majority) of its members hold the relevant license. A law firm, PLLC, typically can't admit a non-attorney as a full member.

When a member dies or loses their license, most states require the PLLC to purchase that member's interest or facilitate its transfer to another licensed professional.

Pros and cons of PLLCs

PLLCs offer a credible structure for professional practices that need a recognized entity form alongside their licensing board requirements:

• State-recognized professional entity: Many states require licensed professionals to operate under a PLLC or professional corporation rather than a standard LLC.
• Personal liability protection for general business debts: Like an LLC, a PLLC separates your personal assets from business liabilities, such as leases, vendor contracts, and business loans.
• Pass-through taxation: You report income and losses on your personal return, avoiding the double taxation that comes with a C-Corp.
• Flexible management: You can organize as member-managed or manager-managed, just like a standard LLC.

PLLCs also come with real limitations that don't apply to standard LLCs:

• Not available in all states: Several states, including California, don't recognize the PLLC as a valid entity type; licensed professionals in those states typically organize as a professional corporation instead.
• Personal malpractice liability is not eliminated: In most PLLC states, each member remains personally liable for malpractice claims arising from their own acts and, in some states, from the acts of people they directly supervise.
• Ownership restricted to licensed professionals: You can't bring on a business-side partner or non-licensed co-founder as a full member without potentially violating your state's PLLC rules.
• More complex formation: PLLC formation typically requires approval from the relevant state licensing board, in addition to filing articles of organization with your state's Secretary of State office.

The personal malpractice exposure that a PLLC cannot eliminate is the reason most states that authorize the structure also require professional liability insurance, either as a formal condition of formation or through the licensing board.

Before you file, confirm your state's insurance requirements and minimum coverage thresholds. For most licensed professions, that coverage is non-negotiable regardless of entity structure.

PLLC business compliance tasks

Annual compliance for a PLLC mirrors LLC requirements plus licensing board obligations. Most states require an annual report filed with the Secretary of State, a current registered agent, and a maintained operating agreement.

On top of that, all members must keep their individual professional licenses in good standing. If a member's license lapses, it can affect the PLLC's authorization to practice in that state.

How do you form a PLLC?

Forming a PLLC generally follows the same path as forming an LLC, with additional steps:

1. Confirm your state recognizes PLLCs for your specific profession.
2. Check whether your licensing board requires pre-approval before you file with the Secretary of State.
3. File your articles of organization, naming the professional services the entity will provide.
4. Draft an operating agreement that reflects your state's membership and licensing requirements. If you plan to practice across state lines, you'll also need a Certificate of Authority from each state where you operate.

The licensing board approval step is the main reason PLLC formation takes longer than a standard LLC. It also serves a practical function: the approval process confirms that your entity structure is appropriate for your profession and state before you start seeing clients or patients under the entity name.

If approval is delayed, do not begin operating under the PLLC until it clears.

Exploring Limited Liability Companies for founders and operators

An LLC (Limited Liability Company) is the most widely used business structure in the US. It combines personal liability protection for its members with pass-through taxation, without requiring the formal governance structure of a corporation.

There's no board of directors, no mandatory annual meetings, and no requirement for formal minutes, though maintaining a clear operating agreement is still good practice.

LLCs are available in all 50 states, with no restrictions on who can be a member. You can form one as a solo founder, with partners, or with a mix of individuals and entities. That flexibility makes the LLC or sole proprietorship question one of the first ones most new businesses face, since the LLC offers liability separation that sole proprietorships simply don't provide.

Pros and cons of LLCs

LLCs work well for a wide range of businesses because of how few structural constraints they carry:

• Available in all 50 states: You can form an LLC anywhere in the US, regardless of your profession.
• No ownership restrictions: Members can include individuals, corporations, other LLCs, or foreign nationals. There's no licensing requirement.
• Full personal liability protection: An LLC shields members from the business's debts and liabilities, and from the general business acts of co-members, as long as you maintain the entity properly and don't commingle funds.
• Multiple tax elections available: Single-member LLCs default to sole proprietorship taxation; multi-member LLCs to partnership taxation. You can also elect S-Corp or C-Corp treatment through IRS filings.
• Simpler to form: No licensing board approval is required. You file with the Secretary of State, and you're operational.

LLCs also have real limitations worth accounting for:

• Not recognized as a professional entity in some states: States that require licensed professionals to operate under a PLLC or professional corporation won't accept a standard LLC as a valid practice structure.
• Self-employment taxes for active members: Members who actively work in the business pay self-employment tax on their share of income unless they elect S-Corp treatment and pay themselves a reasonable salary.
• No professional identity at the entity level: A standard LLC doesn't communicate the licensed nature of your practice to clients or licensing boards the way a PLLC does.

For businesses outside regulated professions, those limitations rarely change the calculus. The LLC's combination of liability separation, flexible ownership, and simple formation has made it the default starting point for most US businesses, and the ongoing compliance requirements reflect that simplicity.

LLC business compliance tasks

LLC compliance is simple: file your annual report with the Secretary of State, keep a registered agent on record, and maintain your operating agreement.

Opening a dedicated business bank account and keeping it separate from your personal finances isn't legally required, but commingling funds is one of the most common reasons courts pierce the liability shield. If you don't renew your LLC on time, your state may administratively dissolve it, which eliminates your liability protection.

How do you form an LLC?

Forming an LLC takes five steps:

1. Choose a name that complies with your state's naming rules
2. Designate a registered agent
3. File articles of organization with the Secretary of State
4. Draft an operating agreement
5. Obtain your Employer Identification Number (EIN) from the IRS, along with any required business licenses

If you plan to operate in a state other than the one where you formed, you'll need a Certificate of Authority from that additional state before you can legally conduct business there.

How does an LLC distribute profits among members?

LLCs can distribute profits to members in any proportion specified in the operating agreement; it doesn't have to track ownership percentages. A member who contributes more active labor might receive a larger distribution than their equity stake alone would suggest.

That flexibility makes LLCs work well for partnerships where contributions aren't purely financial, and it's one reason operators prefer them over corporations when structuring a small team.

PLLC or LLC? Which is right for your business

If your state requires licensed professionals to use a specific entity structure, your choice is already made, so check your state's statutes and your licensing board's requirements before you file anything.

If you're a licensed professional in a state that allows either structure, a PLLC is usually the right call: it's what your licensing board expects, and it signals to clients and courts that they're dealing with a licensed professional practice.

If you're not a licensed professional or if you're in a state that doesn't recognize PLLCs for your field, an LLC is the right default. It's available everywhere, imposes no ownership restrictions, and offers the same pass-through taxation you'd get from a PLLC.

For licensed professionals focused on building business credit and separating their professional finances, both structures accomplish that goal once the entity is in place and you've opened dedicated accounts.

Understanding professional liability insurance is a natural next step after you've chosen your entity structure. Your PLLC or LLC sets the liability framework at the entity level, and your insurance policy is what actually covers you when a professional claim arrives.

Frequently asked questions about PLLC vs LLC

What professions typically use a PLLC?

The professions most commonly organized as PLLCs include physicians, dentists, attorneys, CPAs, architects, and engineers. The exact list varies by state; some allow a broader range of licensed professionals to use the PLLC form, while others limit it to a few specific fields. Check your state's statutes and your licensing board's requirements before filing.

Can an LLC be converted to a PLLC?

In most states that recognize both structures, you can convert an existing LLC to a PLLC by amending your articles of organization and obtaining approval from the relevant licensing board. The specific steps vary by state, so confirm the conversion process with your Secretary of State's office before starting.

Do PLLCs pay more in taxes than LLCs?

No. Both PLLCs and LLCs use pass-through taxation by default, so members report income on personal returns without an entity-level tax. Both structures can elect S-Corp treatment through IRS Form 2553, which lets you pay yourself a reasonable salary and take remaining profits as distributions, potentially reducing your self-employment tax exposure.

Is a PLLC better than a professional corporation?

It depends on your state and profession. A PLLC generally offers more management flexibility and simpler annual compliance than a professional corporation. In states that don't recognize PLLCs, a professional corporation is often the required alternative for licensed practitioners. Where you have a choice, most practitioners prefer the PLLC for its operational simplicity.

Can a PLLC have non-licensed members?

Most states restrict PLLC membership to licensed professionals in the relevant field. A few states allow a small percentage of ownership by non-licensed individuals, but that's the exception. If you need a non-licensed partner or investor as a full member, a standard LLC is the more flexible structure.
