3 Steps to Starting Your Physician Assistant (PA) Corporation

Why Physician Assistants in California Must Form a Professional Corporation

If you’re a licensed Physician Assistant (PA) in California, you cannot form an LLC or a traditional general corporation for your medical practice.

Under the Moscone-Knox Professional Corporation Act (California Corporations Code §§13400–13410), PAs must form a Professional Corporation to legally provide medical services.

Filing incorrectly can lead to rejection by the Secretary of State, state penalties, lawsuits, or even disciplinary action from the Medical Board of California.

At All-in-Juan Business Consultancy Services, we’ve helped thousands of California professionals, including Physician Assistants, properly establish their Professional Corporations while staying 100% compliant with state law.

A Physician Assistant Professional Corporation is a legal business entity registered with both:

  • The California Secretary of State, and

  • The Medical Board of California

It allows Physician Assistants to practice medicine while enjoying limited liability, tax efficiency, and professional compliance.

All such corporations are governed by the Moscone-Knox Professional Corporation Act, which defines ownership, naming, and practice requirements for licensed professionals.


Why Elect S-Corporation Tax Status

By default, professional corporations are taxed as C-Corporations, which can lead to double taxation (corporate + individual levels).

By electing S-Corporation status with IRS Form 2553, Physician Assistants can enjoy:
✅ Pass-through taxation (no double tax)
✅ Reduced self-employment tax
✅ Simpler reporting and payroll
✅ Stronger financial flexibility for owner income


3 Steps to Form a Physician Assistant Professional Corporation in California

Step 1: File Your Articles of Incorporation

Submit the Articles of Incorporation of a Professional Corporation to the California Secretary of State, identifying your business as a Physician Assistant Professional Corporation.

Step 2: Complete All State and Federal Registrations

After formation, complete these key filings:

  • Apply for your EIN from the IRS

  • Appoint Directors

  • Draft your corporate bylaws

  • File your Statement of Information with the Secretary of State

  • File Form 2553 to elect S-Corporation tax status

  • Pay annual taxes to the California Franchise Tax Board (FTB)

  • Register with the Employment Development Department (EDD) if you pay salaries

  • Apply for local business licenses or permits

Step 3: Let All-in-Juan Handle Everything

Instead of navigating California’s complex business regulations on your own, All-in-Juan Business Consultancy Services can handle every step — from filing to final approval — ensuring compliance with the Moscone-Knox Act.

Benefits of a Physician Assistant Professional Corporation

Forming your PA Professional Corporation provides key advantages:
Liability Protection – Separate your personal assets from business obligations.
Tax Efficiency – Elect S-Corp status to reduce self-employment taxes.
Professional Legitimacy – Operate legally under the Moscone-Knox Act.
Business Growth – Build corporate business credit and expand your practice.


Naming Requirements for Physician Assistant Corporations

Your corporation’s name must include the words “Physician Assistant” and one of the following corporate suffixes:

  • “A Professional Corporation”

  • “Professional Corporation”

  • “Prof. Corp.”

  • “P.C.”

  • “Inc.”

  • “Corporation”

  • “A California Professional Corporation”

❌ “LLC” or “Limited Liability Company” cannot be used, as California does not permit Physician Assistants to form or operate as LLCs.


Who Can Be a Shareholder in a PA Professional Corporation?

According to the Moscone-Knox Act and the California Business & Professions Code, ownership must follow strict guidelines:

  • At least 51% of shares must be owned by licensed Physician Assistants.

  • The remaining 49% may be owned by:

    • Licensed Physicians and Surgeons

    • Registered Nurses

    • Licensed Acupuncturists

    • Naturopathic Doctors

    • Licensed Midwives

Non-qualified professionals cannot hold shares, and any unauthorized shares issued are automatically void.

If a shareholder becomes ineligible or disqualified, they must transfer their shares within 90 days to a qualified shareholder or back to the corporation to remain compliant.


Can a Physician Assistant Form an LLC in California?

No.
Physician Assistants cannot form LLCs in California under the
Moscone-Knox Professional Corporation Act.

To legally practice, all Physician Assistants must form a Professional Corporation registered with the Medical Board of California.


Can a PA Corporation Use a DBA or Fictitious Business Name?

Yes — as long as the name:

  • Includes the term “Physician Assistant”,

  • Is not deceptive or misleading, and

  • Has a Fictitious Business Name Statement filed within 40 days of operation.

Fictitious names must also be filed in every county where your business operates.
