Entity Types and Filing, Decoded

What entity type should a solo psychiatrist use? In most states, a Professional LLC (PLLC) or Professional Corporation (PC) - whichever your state allows for licensed medical practice - with an S-Corp tax election once you are reliably profitable. A regular LLC is often not legal for practicing medicine; a sole proprietorship is almost never worth the lost liability structure.

Most “start a medical practice” articles end with “consult an attorney.” That is not wrong, but it leaves you with no framework for which attorney or what to ask. This piece is the decision map: the five structures people actually confuse, what solo psychiatrists typically file, how S-Corp fits in (spoiler: it is not an “entity type”), and the state rules that change the answer.

Most solo psychiatrists end up with a PLLC or PC, taxed as an S-Corp, with themselves as sole owner. Read on for whether that is also right for you.

The five options on the table

Sole proprietorship

Default if you do nothing formal. No separation between you and the business. For malpractice, nothing insulates you from your own clinical acts - but for leases, contracts, and vendor disputes, your personal assets sit exposed. For psychiatry, this is almost never the right long-term structure.

Single-member LLC (non-professional)

Liability shield for many business debts, pass-through taxation by default, relatively simple. Critical: many states do not let physicians practice through a plain LLC. They require a PLLC or PC. Using the wrong label can mean refiling, new EIN headaches, and delayed credentialing.

PLLC (Professional LLC)

The “medical grade” LLC in states that offer it. Same general liability separation as a business LLC for non-malpractice claims - clinical malpractice still requires insurance; no entity fixes that. Ownership is often restricted to licensed professionals in the same field. For many solo outpatient psychiatrists in PLLC-friendly states, this is the common choice.

PC (Professional Corporation)

The corporate counterpart to a PLLC. Some states require a PC for physicians or disallow PLLCs for practice. California is the big one: medical practice uses a professional medical corporation, not a PLLC. PCs can sound scarier because of “corporate formalities,” but in a solo shop, annual minutes are usually lightweight paperwork - not a reason to panic.

S-Corp election (tax status)

Not something you “form” at the Secretary of State. It is an IRS election (Form 2553) on top of an eligible entity (LLC, PLLC, or PC, depending on eligibility). It changes how profit is taxed - not your clinical license type. More on math below.

The state-by-state reality

Fees and statutes change. Treat every dollar figure below as approximate - verify on the state site before you budget. Last reviewed for this article: February 2026.

California

• Required entity: Professional medical PC (often called “professional corporation”). PLLC is not the path for licensed medical practice here.
• Filing (approx.): Articles of Incorporation on the order of ~$100 plus other state corporation taxes and filings (verify current).
• Annual: Minimum $800 franchise tax is the number everyone quotes; plus statement filings.
• Ownership: Typically 100% California-licensed physicians (psychiatrists qualify).
• Gotcha: Name rules and “fictitious name” filings are picky; corporate designators like “Medical Corporation” or “Inc.” matter.

Texas

• Required entity: PLLC or PA (Professional Association), per Texas practice rules.
• Filing (approx.): ~$300.
• Annual: No generic “annual LLC fee” like some states; franchise tax can apply above revenue thresholds.
• Ownership: Texas-licensed physicians.
• Gotcha: Medical board registration is a separate lane from SOS filing - do both.

New York

• Required entity: PC or PLLC for professional practice.
• Filing (approx.): ~$200 to start (verify).
• Annual / ongoing: Biennial statement; PLLC publication requirement can cost $1,000–$2,000+ in NYC newspapers, less upstate.
• Ownership: NY-licensed professionals.
• Gotcha: Budget publication before you are surprised.

Virginia

• Required entity: PC or PLLC.
• Filing (approx.): ~$100.
• Annual: ~$50 registration (verify current).
• Ownership: VA-licensed practitioners.
• Gotcha: Generally one of the lighter-weight filings relative to peer states.

Massachusetts

• Required entity: PC for medical practice; PLLC is not the approved vehicle for physicians the way many expect.
• Filing (approx.): ~$275.
• Annual: Annual report; modest fee (verify).
• Ownership: MA-licensed practitioners.
• Gotcha: Do not assume PLLC because you used one in another state.

Florida

• Required entity: PA or PLLC for professional practice.
• Filing (approx.): ~$125.
• Annual report (verify current): often cited around $138.75 - confirm on Sunbiz.
• Ownership: Florida-licensed professionals.
• Gotcha: Florida is relatively straightforward; many solo psychiatrists choose PLLC when allowed.

The S-Corp tax election (the move that actually matters)

Why it exists

By default, pass-through entities often face self-employment tax on essentially all practice profit - roughly 15.3% on the first chunk of earnings (the Social Security wage base changes yearly; verify current thresholds), then 2.9% Medicare, with possible additional layers at higher income.

An S-Corp splits cash into W-2 wages (subject to payroll taxes) and distributions (not subject to self-employment tax in the same way). For profitable practices, that difference is often the largest single tax lever short of retirement planning.

How the math can look (illustrative)

Suppose Dr. Patel nets about $400,000 in practice profit. As a default pass-through taxed like a sole prop, a large share of that profit can get hit with SE tax - think on the order of ~$25k in SE tax burden beyond ordinary income tax (illustrative; your CPA models the real return).

As an S-Corp paying a reasonable salary of, say, $200k and taking the rest as distributions, SE/payroll tax applies to the salary portion, not the full $400k. Net savings after payroll costs might land around $6k–$10k+ in many scenarios - sometimes more, sometimes less. This is why the election exists.

Reasonable salary

The IRS wants the W-2 to reflect reasonable compensation for the work you do. For full-time psychiatry, salaries in the $180k–$250k+ range often enter the conversation depending on hours, geography, and subspecialty. Setting an artificially low salary to dodge payroll tax is a known audit magnet. Bureau of Labor Statistics and comp surveys are the boring, defensible references your CPA will want.

When it is not worth it

• Net income under roughly $80k/year: payroll + separate return + accountant time can eat the benefit.
• First chaotic year with uncertain revenue: some practices wait until year two when numbers stabilize.
• You are winding down or selling imminently: ask your CPA before you lock elections.

How to elect

File IRS Form 2553, typically within 75 days of forming the entity or by March 15 of the tax year you want S status to begin (rules have nuance - this is the headline deadline everyone misses). Most CPAs handle this for you. The election stays in place until revoked.

Multi-state practice (telehealth)

If you are licensed in multiple states and treat patients in those states from one home base, you may need to register your entity as a foreign entity in states where you do business. “Foreign” means out-of-state, not international. Each state charges registration and often annual fees; enforcement varies.

Psychiatrists are not in PSYPACT - that compact is for psychologists. You are generally juggling individual state medical licenses. If you bill through your entity in several states, map foreign qualification with a healthcare-savvy attorney or CPA.

If you practice in five or more states seriously, foreign registrations alone can run $1,500–$3,000/year in fees before you count compliance time. Factor that into whether to expand the map.

How to actually file (practical steps)

1. Pick PC vs PLLC (or PA) based on your state’s medical board + SOS guidance.
2. Check your state medical board for any name or pre-formation requirements.
3. Choose a registered agent (you can often be your own; commercial agents run about $100–$200/year if you want privacy).
4. Draft a compliant name with required suffixes (“PLLC,” “P.C.,” “Medical Corporation,” etc.).
5. File Articles of Organization or Articles of Incorporation online with the Secretary of State (most states).
6. Pay the filing fee and wait for stamped approval (1–4 weeks typical).
7. Get your EIN from the IRS the same day the entity exists.
8. File Form 2553 for S-Corp if your CPA says you are ready.
9. File any state-level S-Corp election if your state piggybacks (some do).

You do not need a $300–$800 incorporation website for a solo practice if you can read a one-page state form. The state portal is usually the same data; the service is markup plus mail forwarding. Spend the money on a CPA who knows physicians instead.

Common mistakes

• Forming a plain LLC where the state requires a PLLC/PC - then paying twice to fix it.
• Missing the S-Corp election deadline and losing a year of treatment.
• Setting a comically low S-Corp salary and inviting IRS scrutiny.
• Using Delaware/Wyoming because a podcast said so - then foreign-qualifying in your real state and paying double fees.
• Using your SSN everywhere because you skipped the EIN - payers and vendors should not get your personal number if you can avoid it.
• Never opening a separate bank account, undoing the liability story you paid to build.

What about Delaware, Wyoming, or Nevada?

Those jurisdictions market “business-friendly” laws that matter far more to tech startups, holding companies, and asset-heavy operations than to a psychiatrist earning income where you live and see patients. Your practice income is generally taxed where you practice, not where a shell entity sits.

If you form out of state, you still foreign-register at home. You pay two filing regimes. For solo outpatient psychiatry: form in the state where you practice. Always.

Entity choice feels existential; for most solo psychiatrists it is not. The right answer is usually PC or PLLC (state-dependent) + S-Corp once you are profitable. The rest is paperwork. Pay a physician-friendly CPA to own the election and your payroll - it is among the highest-return professional fees in the whole launch.
