The difference between an LLC and a PLLC comes down to who can form one and what the liability shield actually covers. A standard limited liability company is available to almost any lawful business and protects every member’s personal assets from the company’s debts and lawsuits. A professional limited liability company, or PLLC, is reserved for people who hold a state-issued professional license, and while it protects members from each other’s malpractice claims, it never protects a professional from their own negligent acts. Your state’s rules decide whether a PLLC is even on the table: roughly a dozen states don’t recognize the entity at all.
The Liability Difference That Actually Matters
In a standard LLC, members are generally shielded from all business liabilities. If the company is sued over a contract dispute, a slip-and-fall, or an unpaid vendor invoice, creditors can pursue the LLC’s assets but not the members’ homes, savings, or other personal property. The protection runs broadly across the kinds of claims a business tends to face.
A PLLC gives you that same protection against business debts and general liabilities. It diverges on professional malpractice. Each member of a PLLC remains personally liable for their own professional negligence. If a physician in a three-member medical PLLC commits malpractice, the injured patient can go after that physician’s personal assets. The other two physicians, though, are shielded. Their personal property is off-limits for a partner’s professional mistake.
That cross-liability protection is the main reason group practices use PLLCs. Without it, a surgeon in a five-doctor practice could lose personal assets because a colleague in a different specialty made an error the surgeon had nothing to do with. The PLLC prevents that outcome while keeping each professional accountable for their own work.
Who Can Form Each One
Almost anyone can form a standard LLC for almost any lawful purpose. Retail shops, restaurants, tech startups, freelance consultants, real estate investors, and e-commerce businesses all commonly use them. There are no licensing requirements, and membership is open to individuals, other LLCs, corporations, and in most states, foreign nationals.
PLLC ownership is far more restrictive. Most states require every member to hold an active professional license in the field the PLLC practices. Physicians, attorneys, certified public accountants, architects, engineers, dentists, veterinarians, and psychologists are the typical members. The exact list of qualifying professions varies by state, but the common thread is work that requires a license from a state regulatory board. An unlicensed person generally cannot own any stake in a PLLC, even as a passive investor. Some states allow limited non-professional ownership, often capped below 50 percent, but that’s the exception. If a member’s license lapses or is revoked, many states require that person to divest within a set period.
One other wrinkle: many states prohibit licensed professionals from using a standard LLC to deliver professional services at all. If that’s the rule in your state, forming an LLC when you should have formed a PLLC can get the filing rejected or, later, cost you the liability protection you thought you had.
Formation and Naming
For a standard LLC, you file articles of organization with the secretary of state, pay the filing fee, and you’re finished. The name has to include a designator like “LLC” or “Limited Liability Company,” with minor variations by state.
A PLLC adds a layer. Most states require approval from the relevant professional licensing board before the secretary of state will accept the filing. That typically means submitting proof of each member’s active license, and in some states obtaining a letter or certificate from the board confirming members are in good standing. The name has its own designators, which vary by state and often include “PLLC” or “Professional Limited Liability Company,” and it must also comply with the licensing board’s naming rules. Some boards restrict certain terms or require the profession to be identifiable from the name. Getting it right before filing avoids amending formation documents later.
Ongoing Oversight and Insurance
Standard LLCs answer to one authority for formation and compliance: the secretary of state or equivalent filing office. Annual or biennial reports, a registered agent, and franchise taxes are the usual ongoing obligations.
PLLCs answer to two authorities. The licensing board governing the profession keeps jurisdiction over the entity on top of the secretary of state’s requirements. Boards can impose rules about who supervises work, how client records are kept, continuing education for members, and ethical standards. A board that finds a violation can act against the PLLC’s authority to practice, independent of anything the secretary of state does.
Some states also require PLLCs to carry malpractice insurance or post a surety bond as a condition of formation or continued operation. A few mandate minimum coverage amounts for certain professions; others leave the question to the licensing board. Even where insurance isn’t legally required, most PLLCs carry professional liability coverage, since members’ personal assets are exposed for their own negligent acts.
Taxes
Federal tax treatment is identical. The IRS classifies both based on the number of members and any elections made, not on whether the entity is “professional.” A single-member LLC or PLLC defaults to sole proprietorship taxation, a multi-member entity defaults to partnership taxation, and either can elect S corporation or C corporation treatment by filing the appropriate form.1Internal Revenue Service. Limited Liability Company (LLC) State tax treatment generally mirrors standard LLC taxation, though a few states add fees or taxes on professional entities. Choosing a PLLC over an LLC doesn’t change your federal tax picture.
States That Don’t Allow PLLCs
Not every state has a PLLC statute. Roughly a dozen states, including California, Delaware, Alaska, Georgia, Hawaii, Maryland, Missouri, New Jersey, New Mexico, South Carolina, Wisconsin, and Wyoming, either don’t have PLLC statutes or don’t permit their formation. If you practice in one of these states, the usual alternative is a Professional Corporation, sometimes called a Professional Service Corporation or Professional Association. California, for instance, requires licensed professionals to form professional corporations instead. Some states allow licensed professionals to use standard LLCs or limited liability partnerships. The right choice depends on your state’s statutes and your licensing board’s rules.
PLLC vs. Professional Corporation
When a state offers both, the choice usually comes down to formality. A Professional Corporation operates like a traditional corporation: it issues shares, adopts bylaws, elects a board of directors, and holds regular meetings. A PLLC has fewer formalities and more freedom to structure management and profit-sharing through an operating agreement.
The malpractice liability rule is the same in both. Individual professionals are personally liable for their own negligent acts but shielded from other members’ or shareholders’ professional mistakes. Both restrict ownership to licensed professionals in most states, and both typically require licensing board approval before formation. Tax treatment runs parallel too: both can elect pass-through taxation or opt for corporate taxation. Many professionals prefer the PLLC for simpler ongoing compliance; others choose a Professional Corporation because state law or their licensing board requires it.
How To Decide
Start with two questions. Does your work require a professional license? And does your state have a PLLC statute?
If your work doesn’t require a license, a standard LLC is almost certainly right. You get full liability protection, flexible management, and the ability to bring in any type of investor or co-owner. Most states wouldn’t let you form a PLLC anyway.
If your work does require a license, check whether your state mandates a professional entity for your specific field. Where it does, forming a standard LLC when you should have formed a PLLC can get the filing rejected or cost you liability protection later. If your state offers PLLCs and your licensing board approves them for your profession, a PLLC gives you the operational flexibility of an LLC with the accountability framework your state requires. If your state doesn’t have a PLLC statute, a Professional Corporation or LLP will be the likely alternative.
Confirm requirements with both the secretary of state’s office and your professional licensing board before filing. And regardless of entity type, carry professional liability insurance. No business structure eliminates the risk of a malpractice claim tied to your own work.
