Do You Need a PLLC to Start a Private Practice?
No, you do not need a PLLC to start a private practice. You do not need an LLC, a PC, or any business entity at all to legally see your first patient. You can practice as a sole proprietor, report your income on a Schedule C, and never incorporate, and plenty of clinicians run that way for an entire career. What you actually need before patient one is an active license, malpractice coverage, a way to document, and a way to get paid. The entity question comes later, and it is mostly a tax question, not a permission question.
This trips people up because forming an entity feels like the official first step, the thing that makes the practice real. It is not. Treating it as step one is one of the most common ways new practices stall for months, and a surprising number of clinicians spend real money setting up the wrong entity before they have a single patient to bill. Here is what the decision actually involves, so you can make it once and move on.
This is general information, not legal or tax advice. Entity rules vary by state and by license, so confirm the specifics with a CPA or attorney licensed where you practice before you file anything.
Does a PLLC protect you from a malpractice lawsuit?
No. This is the single most important and most misunderstood fact about incorporating a medical practice: a PLLC, LLC, or professional corporation gives you essentially zero protection against a malpractice claim arising from your own clinical care.
The limited-liability shield people imagine protects personal assets from business debts and from things like a contract dispute or a slip-and-fall in your office. It does not protect a licensed professional from liability for their own professional negligence. If you are sued for how you treated a patient, the plaintiff can reach you personally regardless of whether you incorporated. The entity is not standing between you and that claim.
What does protect you is malpractice insurance. That is the real shield, and it is non-negotiable from day one. If your only reason for rushing to form a PLLC is liability protection, you are buying the wrong product. Buy the malpractice policy, see patients, and decide on the entity on its own merits, which are almost entirely about taxes. (For premises risk like that office slip-and-fall, cheap business or home liability coverage handles it.)
LLC vs PLLC vs PC vs S-corp: what these words actually mean
The confusion here comes from mixing two different decisions into one. They are separate, and once you see them as separate the whole topic gets simpler.
The first decision is your entity type: sole proprietor, LLC, PLLC, or professional corporation (PC). This is governed by state law, and for licensed clinicians the state usually dictates which one you are allowed to use. A PLLC is just an LLC for licensed professionals; a PC is the corporate equivalent. Sole proprietor is the default that requires no filing at all.
The second decision is your tax status: how the IRS taxes whatever entity you formed. An LLC or PLLC is taxed as a sole proprietorship by default, but you can elect to have it taxed as an S-corp. S-corp is not a separate kind of company you go form at the Secretary of State. It is a tax election you layer on top of your existing entity.
So "LLC vs S-corp" is a false choice. They are answers to different questions. For most solo practices that decide to incorporate, the end state is a PLLC or PC that has elected S-corp tax treatment. You pick the entity type your state requires, then elect S-corp taxation when the numbers justify it.
Which entity does your state require?
This is the part that actually has a wrong answer, and getting it wrong is expensive. Most states require licensed clinicians to use a PLLC rather than a plain LLC. Several go further:
| State pattern | What licensed clinicians typically must form |
|---|---|
| Most states | PLLC (not a regular LLC) |
| California | Professional Corporation. Physicians form a Medical Corporation; nurse practitioners must form a Nursing Corporation, not a Medical Corporation. No LLCs for these practices. |
| Texas, Pennsylvania, North Carolina, Massachusetts | PLLC |
| Connecticut | PLLC commonly required even to open a business bank account |
Treat that table as illustrative, not authoritative for your situation. The rules change and vary by license type, so verify yours with two sources: your Secretary of State's office and your licensing board (your medical board, or your board of nursing if you are an NP). They will tell you the exact entity type your license requires.
The trap to know about: the big automated formation websites will happily let you file a plain LLC without warning you that your license requires a PLLC or a professional corporation. Some of them will not process professional-entity filings through their standard online flow at all, and quietly refund you, which is actually the lucky outcome because at least you find out before you build on the wrong foundation. The unlucky version is real. We have seen a nurse practitioner in a PLLC-only state lose more than ten thousand dollars and over a year of launch time after an advisor and several state offices steered her into the wrong structure, then having to dissolve it and start over with a new entity, new EIN, and new accounts. The California "I formed a Medical Corp but NPs can only own a Nursing Corp" mistake is the same category. None of this is hard to get right. It is just easy to get wrong if you file blind.
When is it worth incorporating at all?
For most solo practices, incorporating starts paying off around $100,000 in net (post-expense) revenue in a tax year, which usually means year two rather than year one. Below that, the costs of having an entity tend to outweigh the savings.
The benefit is tax savings from the S-corp election, and it is real but modest, often in the low thousands of dollars a year. The mechanism: instead of paying self-employment tax on all your profit, you pay yourself a reasonable W-2 salary and take the rest as a distribution that is not subject to self-employment (Social Security and Medicare) tax. Your accountant sets the salary split. Do not lowball the salary, because an unreasonably low one invites IRS scrutiny.
Against that savings, weigh the costs: the filing fee, a pricier accountant-prepared corporate tax return each year, and in some states an annual entity tax whether or not you profit. California's $800 minimum annual franchise tax is the most famous example, and it alone can erase a first-year practice's tax savings. That math is why the common advice is to start as a sole proprietor and incorporate in year two, once your income clears the threshold where the S-corp savings beat the overhead.
There are two good reasons to incorporate from day one anyway:
- To avoid redoing your accounts later. If you open a sole-proprietor bank account and merchant account now, you will have to close and reopen them under the entity when you incorporate. Some people would rather do it once.
- To run a cash practice alongside an insurance-credentialed day job. If your individual (Type 1) NPI is already credentialed with insurers through an employer, forming a corporation with its own EIN and organizational (Type 2) NPI lets you keep your cash practice billing cleanly separate. This is a real reason to incorporate early, and it ties into the broader NPI Type 1 vs Type 2 question that deserves its own guide.
If neither of those applies, there is no penalty for waiting.
What it costs and who should file it
You have four ways to form the entity, and the right one for a solo practice is rarely the most expensive.
| Who files it | Rough cost | When it makes sense |
|---|---|---|
| Do it yourself | State filing fee only | You are comfortable reading your state's rules and mailing forms |
| Online formation service | A couple hundred dollars plus state fees | You want it handled but cheaply; confirm they will file a PLLC or PC |
| Accountant | Around $600, often bundled with tax services | The default best option: they file it and advise on entity type and S-corp timing |
| Attorney | Roughly $1,300 for a full package | Multi-owner practices, shareholder agreements, complex ownership |
For a solo practitioner, an accountant who works with medical practices is usually the best first call, because they handle both halves of the problem: filing the correct entity and telling you when the S-corp election will actually save you money. A lawyer is overkill for a simple solo filing. If anyone quotes you $5,000 to incorporate a one-person practice, walk away; this is largely a matter of choosing the right entity type and submitting a form.
Two cautions from clinicians who learned the hard way. First, vet the advisor for your specific context: the most expensive mistakes came from accountants and attorneys who did not understand healthcare licensing rules in the relevant state, especially for nurse practitioners. The filter worth applying is simple, work only with someone licensed in the state where you practice who has set up entities for clinicians with your credential. Second, a personal referral to a healthcare-savvy CPA beats cold-calling firms, most of which are not taking new clients and will not call you back.
One small practical note for when you do form the entity: the corporation's legal name does not have to match your practice brand, but it does show up on your patients' credit card statements. Keep it clear enough (with "psychiatry" or your name visible) that patients recognize the charge, or you will field avoidable "what is this charge" disputes. Whatever system you use to collect payment, this is worth getting right up front. With Eureka's card-on-file billing, the statement descriptor is something you can set so charges read cleanly to patients from the first visit.
So what should you actually do?
If you are starting out, the sequence is straightforward:
- Get your license, malpractice coverage, a way to document, and a way to get paid. Start seeing patients as a sole proprietor.
- Get a free EIN from the IRS so you are not handing your Social Security number to vendors, and open a sole-proprietor business account if you want clean books now.
- Sometime in year one, ask an accountant who knows healthcare in your state two things: which entity type your license requires, and at what income it is worth electing S-corp treatment.
- Incorporate when the numbers say so, usually year two, choosing the entity type your state mandates (PLLC in most states, a PC or nursing corporation in places like California).
The thing not to do is freeze. Forming an entity is not what makes you a real practice and it is not what protects you from a lawsuit. It is a tax optimization you layer on once you are earning enough for it to matter. The clinicians who get stuck are usually the ones treating entity formation as the gate they have to pass through before seeing anyone, when the truth is the opposite: see patients first, optimize the structure second. For the full picture of what genuinely has to be in place before patient one, see what you actually need to see your first private practice patient.
Frequently asked questions
- Can I open a business bank account without an LLC or PLLC?
- In most states, yes. Get a free EIN from the IRS and open a sole-proprietor business account with it. A few states are stricter (Connecticut, for example, has required a registered entity before a bank will open a business account), so confirm with your bank and state. The one tradeoff is that if you incorporate later, you will usually have to close the sole-proprietor account and open a new one under the entity.
- Can I convert an existing LLC to a PLLC instead of starting over?
- Often, but not always, and the path is state-specific. Some states let you convert or amend your filing; others want you to dissolve the LLC and form the PLLC fresh, which means a new entity, sometimes a new EIN, and new bank accounts. Call your Secretary of State's office and your licensing board before you assume either way, because guessing wrong here is what turns a clerical fix into a costly redo.
