PLLC vs LLC: Which One Do You Need?
A PLLC and an LLC are close cousins, and for most purposes they behave identically. But the differences that do exist, around who may own them, what liability they cover, and what it takes to form them, decide the question for you before you ever get to weigh preferences. In many cases, your state and your license make the choice for you.
This comparison walks through each difference so you can see clearly which structure fits your practice or business.
The Short Answer
If you are a licensed professional in a state that requires or offers a PLLC for your profession, form the PLLC. If you are not a licensed professional, or your state does not restrict your profession to a professional entity, form a regular LLC. That covers the great majority of cases. Everything below explains why.
Ownership: Who May Be a Member
This is the fundamental divide. A regular LLC can be owned by anyone: individuals, corporations, other LLCs, even foreign entities. There are no professional qualifications for membership.
A PLLC restricts ownership to licensed professionals, generally all holding the same professional license the company is organized around. A medical PLLC’s members must be licensed physicians. Unlicensed investors, family members without licenses, and business partners from other fields cannot hold ownership interests in most states. If your business plan involves outside investors, the PLLC structure will fight you.
Liability: What Each One Shields
Both structures protect members’ personal assets from the business’s general debts: leases, vendor contracts, and business loans gone bad. On that front they are equals.
The difference appears with professional negligence. Neither structure shields you from liability for your own malpractice. A surgeon in a PLLC and a surgeon in a regular LLC face the same personal exposure for their own surgical errors. The PLLC’s edge is narrower: it protects each member from the malpractice of the other members. In a group practice, Dr. A’s error does not put Dr. B’s personal assets at risk. A regular LLC used by professionals in a state that allows it may not offer that same cross-protection as cleanly, which is one reason states created the PLLC in the first place.
Either way, malpractice insurance is non-negotiable. Entity structure manages business risk. Insurance manages professional risk. For the full picture of what a PLLC covers, see our guide on what a PLLC is.
Formation: Paperwork and Approval
Forming a regular LLC is straightforward: file articles of organization, appoint a registered agent, pay the fee. Most states process filings in days.
A PLLC adds licensing gates. You must typically document each owner’s professional license with the filing, and many states route the application through the relevant licensing board for approval before accepting it. Some states require special purpose language in the articles. The process takes longer, costs more, and can stall if a board has questions. Ongoing, most states require owners who lose their licenses to divest, and annual filings may require certification that all members remain licensed.
Taxes: No Difference at All
For federal tax purposes, a PLLC is an LLC. Single-member PLLCs are disregarded entities. Multi-member PLLCs default to partnership taxation. Either can elect S corp or C corp taxation with the same forms and the same rules. Nothing about the “P” changes your tax return. If tax planning is your main concern, read our beginner’s guide to LLC taxation and the S corp election numbers; both apply to PLLCs unchanged.
One tax nuance deserves mention for practices: because professional income is earned through personal services, the IRS and courts scrutinize S corp salary levels in professional firms with particular interest. A medical or legal practice electing S corp taxation should be especially careful to set salaries at genuine market rates, since the service-based nature of the income makes aggressive salary planning harder to defend.
State-by-State Wrinkles
States diverge sharply here, so generalizations are dangerous. New York requires licensed professionals to use a PLLC or professional corporation; a standard LLC is not an option for them. California goes further and bars professionals from LLCs and PLLCs alike, pointing them to professional corporations. Texas, Florida, and many others allow professionals to choose between a PLLC and a regular LLC, with the PLLC adding board oversight.
Because the rules are state-specific and profession-specific, your licensing board is the authoritative source, not a blog post. Check the board’s entity requirements before you pay any filing fee. Our state fee guide can help you budget once you know which entity your state expects.
Which One Do You Need?
Work through this decision tree. Are you a licensed professional? If no, form an LLC. If yes, does your state require a PLLC or professional corporation for your profession? If yes, form what the state requires. If your state gives you the choice, weigh simplicity against the PLLC’s cross-protection: solo practitioners often do fine with a regular LLC where allowed, while multi-member practices usually benefit from the PLLC’s shield between partners.
And in every case, keep the entity decision separate from the tax decision. Whether you form a PLLC or an LLC, the question of S corp taxation comes later and depends on your profit, as our threshold guide explains.
Three Real-World Scenarios
Theory is useful, but most owners decide with a concrete situation in mind. Here are three.
Scenario one: you are a dentist opening your first practice in Texas. Texas allows both LLCs and PLLCs for dentists, but your dental board expects professional entities to meet its requirements. Form the PLLC. The licensing-board approval adds a few weeks, but you get the cross-protection between future associate dentists and full compliance with board expectations. The SBA’s business structure guide notes that professional-entity rules like these are exactly why the PLLC exists.
Scenario two: you are a freelance marketing consultant with no professional license. The PLLC is not available to you and would not help if it were. Form a regular LLC, keep your bookkeeping clean, and revisit the S corp tax election when your profit justifies it.
Scenario three: you are two architects forming a firm in New York. New York requires design professionals to use a PLLC or professional corporation; a standard LLC is off the table. Form the PLLC, submit both partners’ licenses, and complete the state’s publication requirement. The IRS treats your PLLC like any multi-member LLC for tax purposes, so your tax planning proceeds normally from there.
Notice how each scenario was decided by licensing status and state law before preferences entered the picture. That is typical. Get the entity your board requires, then optimize taxes within it. If your situation matches none of these, start with two questions: does my profession require a state license, and does my state restrict my profession to a professional entity? Your licensing board’s answers will point to the right form in most cases.
Frequently Asked Questions
Can a non-professional own part of a PLLC?
Generally no. Most states require all PLLC owners to hold the relevant professional license. Unlicensed spouses, investors, and partners cannot hold membership interests, which makes PLLCs a poor fit for businesses seeking outside capital.
Is a PLLC better than an LLC for a doctor?
In states that require or recognize PLLCs for physicians, yes, because it provides the cross-protection between partners and satisfies licensing-board rules. In states that bar the choice, the question answers itself. Where both are allowed, group practices lean PLLC and solo doctors often choose based on simplicity.
Does a PLLC cost more than an LLC?
Usually. Filing fees for professional entities are often higher, licensing-board review adds time, and you may pay for certified license documentation. Ongoing compliance, like certifying continued licensure, adds modest recurring effort too.
Can I convert an LLC to a PLLC later?
Many states allow conversion or domestication from an LLC to a PLLC, typically requiring license documentation and board approval as part of the filing. The specifics vary, so check with your secretary of state or a local attorney before assuming a path exists.
Do PLLC members still need malpractice insurance?
Absolutely. No entity, PLLC or otherwise, protects you from liability for your own professional negligence. The PLLC handles business debts and partners’ errors. Insurance handles your own professional risk.
