Every business forms an entity the same way; what differs by industry is everything around the filing: which entity variant the regulators accept, which licenses gate the first dollar, which insurance the entity cannot replace, and how the tax posture leans. This guide covers those layers for physicians, dentists, therapists, and licensed health professionals. The universal mechanics (name, agent, filing, EIN, bank account) are in the step-by-step formation guide with fees for every state.
The Entity Choice
Licensed health professionals face a special rule: many states require the professional entity variant (PLLC or professional corporation) and restrict ownership to licensees, and no entity anywhere shields you from your own malpractice. What the entity does protect is everything else: leases, employees, equipment debt, and a colleague's claims. Several states (California most prominently) bar LLCs for medical practice entirely and require professional corporations.
The License Layer
Beyond individual professional licenses, expect entity-level registrations: state professional-entity approval (often with board sign-off on the name and ownership), DEA and state pharmacy registrations where prescribing, NPI numbers, and payer credentialing, which runs on its own slow calendar and gates revenue. Map your specific stack with the license lookup before committing to opening dates.
Risk and Insurance: What the LLC Does Not Cover
Malpractice insurance is the real liability instrument, with the entity handling the commercial risks around it. HIPAA compliance is an operational requirement from day one: business associate agreements, safeguards, and training are part of opening, not scaling. The general principle, that the entity is one wall in a system that includes insurance and clean separation, is developed in What Is an LLC?
The Tax Posture
Practices are personal-service businesses at high rates: the S-corp election (where the professional entity permits it) is the standard optimization once income stabilizes, with the reasonable-salary rules applying at professional pay scales. The mechanics behind all of it (pass-through default, quarterly estimates, the S-corp election) are in the LLC tax guide, with the books that support them in the bookkeeping system.

The Two Mistakes This Industry Actually Makes
Why it hurtsBoards bounce standard LLC filings for licensed practice in many states, costing weeks.
PreventionConfirm the board's entity rules before filing anything.
Why it hurtsPayer credentialing runs months and gates insurance revenue entirely.
PreventionStart it the day the entity is approved.
Standard entity, industry-shaped everything else
Form the entity the standard way, then respect the layers your industry adds: the right variant, the licenses that gate revenue, the insurance the LLC cannot replace, and the tax posture of the work. The businesses that struggle skipped a layer, not the filing.

Can a doctor use a regular LLC?
Depends on the state: many require a PLLC or professional corporation for licensed medical practice and restrict owners to licensees, and California bars LLCs for physicians outright.
