The information on this page is provided for general reference only and may not reflect recent regulatory or legislative changes. Entity formation requirements, tax rates, and CPOM rules vary by state and change frequently. Always verify requirements with your state's official agencies, a qualified healthcare attorney, or a CPA with medical practice experience before making business formation decisions. Nothing on this page constitutes legal or financial advice.

Entity Requirements

Ohio physicians may form a Professional Association under Ohio Revised Code Chapter 1785, a Professional Corporation under Chapter 1701 (with professional designation), or a Professional Limited Liability Company under Chapter 1705/1706. All shareholders or members must be licensed Ohio physicians (with limited exceptions for related professionals).

Filing is with the Ohio Secretary of State.

  • Form a Professional Association, Professional Corporation, or Professional LLC
  • All shareholders/members must be licensed Ohio physicians
  • File Articles of Incorporation, Articles of Organization, or PA Certificate with the Ohio Secretary of State
  • Entity name must reflect professional status (e.g., "Inc.," "PLL," "LLC," "PA")
  • Ohio does not require periodic reports for most entities — verify if your entity type triggers annual filings

Corporate Practice of Medicine

Ohio has a relatively limited Corporate Practice of Medicine doctrine. Ohio law and case authority allow lay corporations to employ physicians under certain conditions, particularly for hospitals and HMOs. The State Medical Board of Ohio does not aggressively enforce a CPOM ban as in CA, NY, or TX.

Fee-splitting is prohibited. MSO arrangements are common and broadly permissible if structured to maintain physician clinical autonomy.

Tax Considerations

Ohio uses a graduated personal income tax with a top bracket around 3.5% (Verify — Ohio has been simplifying brackets). There is no traditional corporate franchise tax. Instead, Ohio imposes a Commercial Activity Tax (CAT) on businesses with Ohio gross receipts above $3 million (threshold raised effective 2024 — verify current).

Municipal income taxes are significant in Ohio — most cities impose a local income tax of 1.5–3% on earned income.

  • Top Ohio personal income tax: Verify — approximately 3.5% (graduated, recent rate cuts)
  • No traditional franchise tax
  • Commercial Activity Tax (CAT) applies above ~$3M Ohio gross receipts (Verify current threshold)
  • Municipal income taxes (typically 1.5–3%) apply in most cities
  • Ohio offers a Pass-Through Entity Tax (PTE) election — discuss with CPA

State Medical Board of Ohio

Ohio does not require general entity registration with the State Medical Board for most physician practices. Individual physicians are licensed; the entity is a Secretary of State registration.

  • No general entity registration with the State Medical Board required
  • All practicing physicians must hold an active Ohio medical license
  • Pain management clinics and certain office-based settings have additional registration requirements

Employment Law Considerations

Ohio is generally employer-friendly. No state-mandated paid sick leave, at-will employment is the default, and non-compete agreements are enforceable if reasonable. Ohio Civil Rights Act parallels federal anti-discrimination protections.

  • At-will employment is the default
  • No state-mandated paid sick leave
  • Non-compete agreements enforceable if reasonable in scope, geography, and duration
  • Ohio minimum wage adjusts annually with inflation (above federal $7.25)
  • Workers' compensation through the Ohio Bureau of Workers' Compensation (BWC) — monopolistic state

Heads up

Ohio is a monopolistic state for workers' compensation — coverage must be obtained through the Ohio BWC, not private insurers. Register before hiring.
