Forming a Professional Corporation in California
Complete guide to establishing a professional corporation in California for licensed experts seeking liability protection and tax benefits.
California mandates that certain licensed professionals organize their practices as professional corporations (PCs) to deliver services requiring state licensure. This structure offers limited liability while adhering to strict regulatory standards designed for fields like medicine, law, accounting, and engineering. Governed primarily by the Moscone-Knox Professional Corporation Act (California Corporations Code §§ 13400 et seq.), PCs provide a shield against personal liability for non-professional debts but maintain individual accountability for malpractice.
Understanding Professional Corporations in California
Unlike standard corporations or LLCs—which professionals in California generally cannot use for licensed services—a PC is tailored for single-profession practices. It allows shareholders to limit exposure to business-related risks while complying with oversight from state licensing boards. Key advantages include potential tax elections like S-corp status to mitigate double taxation risks associated with personal service corporations.
Professionals must hold active California licenses in the specific field the PC serves. Exceptions permit up to 49% ownership by other licensed professionals in designated cases, but the core practice remains profession-specific. PCs require a certificate of registration from the relevant regulatory agency, ensuring ongoing compliance with professional ethics and standards.

Eligibility and Professions Requiring a PC
Any service demanding a license from a California regulatory board, court, or agency qualifies as a professional service. Common examples include:
- Physicians, surgeons, and dentists
- Attorneys (though limited liability partnerships are an alternative)
- Certified public accountants (CPAs)
- Architects and engineers
- Veterinarians and psychologists
Before proceeding, verify with your profession’s licensing body—such as the Medical Board of California or State Bar—for PC-specific rules. Multi-profession PCs are prohibited unless explicitly allowed, preserving the integrity of specialized oversight.
Step-by-Step Formation Process
Forming a PC mirrors general corporation setup but incorporates profession-tailored documents and approvals. Expect 4-6 weeks for standard processing, or faster with expedited options.
Step 1: Select and Reserve a Compliant Name
The PC name must indicate its professional nature (e.g., incorporating ‘Professional Corporation,’ ‘Corporation Professional,’ or abbreviations like ‘PC’ or ‘Prof. Corp.’) and meet profession-specific naming rules from licensing agencies. It cannot conflict with existing entities registered with the California Secretary of State (SOS).
- Conduct a name availability search via the SOS bizfile Online portal.
- Reserve the name for 60 days if needed (fee: $10).
- Secure approval from your regulatory board if required.
Step 2: Prepare and File Articles of Incorporation
Draft Articles of Incorporation for a Professional Corporation (Form ARTS-PC) detailing the purpose statement limited to your licensed services, agent for service of process (with California street address), authorized shares, and initial directors. File online via bizfile.sos.ca.gov, by mail, or in-person with a $100 fee (2024 rate). Professional-specific language is mandatory to comply with Corporations Code and Business and Professions Code.
Upon SOS approval, the PC gains legal existence. Immediately apply for a Certificate of Registration from your profession’s regulatory agency.
Step 3: Establish Internal Governance Documents
Create bylaws outlining operational rules, including ethical standards, officer/director qualifications (must be licensed in the practice area), and board structure. PCs with fewer than three shareholders need at least three directors; solo owners may consolidate roles.
Hold an organizational meeting via Action by Incorporator and Initial Board Minutes to:
- Adopt bylaws
- Elect officers and directors
- Authorize share issuance
- Approve a registered agent
Step 4: Issue Shares and Maintain Records
Only licensed professionals can own shares, with restrictions on non-practicing holders. Issue stock certificates tracking ownership, ensuring compliance with share transfer limits to preserve professional control.
Step 5: Obtain Federal Employer Identification Number (EIN)
Apply for an EIN via IRS Form SS-4 or online at irs.gov—essential for banking, payroll, and taxes. Most PCs elect S-corp taxation (Form 2553) to avoid flat-rate C-corp taxation on personal services.
Step 6: File Initial Statement of Information
Within 90 days of incorporation, submit Form SI-200 to SOS ($25 fee, 2024), listing officers, directors, agent, and business addresses. File biennially thereafter; late filings incur penalties up to suspension.
Step 7: Secure Additional Registrations and Compliance
Obtain your profession’s Certificate of Registration, business licenses, and any local permits. Set up corporate records, including a minute book for ongoing governance.
Governance and Ownership Rules
| Role | Licensing Requirement | Notes |
|---|---|---|
| Shareholders | Primarily licensed in the PC’s profession | Up to 49% by other professionals in select cases |
| Directors | Licensed in the profession | Minimum 3 unless fewer shareholders |
| Officers | Generally licensed | Solo PC: One person may hold multiple roles |
These rules enforce professional accountability while enabling corporate benefits. Bylaws must integrate ethics codes from licensing boards.
Tax Considerations for PCs
PCs default to C-corp taxation, risking double taxation at 9.3% corporate rate plus personal rates. S-election passes income to shareholders, ideal for service firms. Consult a tax advisor; also register for California Franchise Tax Board (FTB) via Form 3522 and pay $800 minimum annual tax.
Ongoing Compliance Obligations
- Biennial Statement of Information ($25)
- Annual FTB returns and $800 tax
- Certificate of Registration renewals
- Professional license renewals for shareholders/officers
- Annual meetings and minutes
Non-compliance risks penalties, suspension, or dissolution.
