Professional Corporation / PLLC Formation Packet — California

Quick-Reference Summary

Topic California Rule
Professional Corporation Act Moscone-Knox Professional Corporations Act, Cal. Corp. Code §§ 13400–13410
PLLC permitted? No — FLAG. California does not allow professional LLCs/PLLCs for licensed professions. Under Cal. Corp. Code § 17701.04(b) (RULLCA), an LLC may not render professional services that require a license, certification, or registration. Licensed professionals use a Professional Corporation (PC) (or, for some professions, a registered limited liability partnership — RLLP).
Filing agency California Secretary of State, Business Programs Division
PC formation document Articles of Incorporation of a Professional Corporation — Form ARTS-PC; $100 filing fee (confirm current fee); file via bizfile Online
Required name designation Per the licensing board's rules and Cal. Corp. Code § 13409. Many boards require the name to include "Professional Corporation," "A Professional Corporation," "Prof. Corp.," "P.C.," or "PC" (some boards require the licensee's name). Confirm the exact requirement with your board.
Licensing-board pre-approval / certificate? Varies by board. Some professions need a certificate of registration from the regulating agency before practicing (Cal. Corp. Code § 13401(b)); others (e.g., those regulated by the Medical Board, Dental Board, Board of Accountancy, Architects Board, Board of Registered Nursing, and several others listed in § 13401(b)) do not need a separate certificate of registration to render services. Confirm with your board.
Who may own shares Only "licensed persons" in the corporation's profession (Cal. Corp. Code § 13406). Certain designated professional corporations may have minority shareholders from related licensed professions, capped so that those licensed persons together own no more than 49% and number no more than the same-profession licensees (Cal. Corp. Code § 13401.5).
Share transfer Shares may be transferred only to a licensed person, a shareholder of the same corporation, a person licensed in the same profession in the jurisdiction(s) where they practice, or a professional corporation; any other transfer is void (Cal. Corp. Code § 13407).
Mandatory buy-back On disqualification: within 90 days; on death: within 6 months — failure can lead to suspension/revocation of the certificate of registration (Cal. Corp. Code § 13407).
Registered agent requirement Yes — California agent for service of process (individual in CA or a registered corporate agent with Form 1505 on file)

Part 1 — Entity Choice in California (PC Only)

FLAG — No PLLC in California. California does not permit Professional Limited Liability Companies. A California LLC may not render professional services requiring a license, certification, or registration (Cal. Corp. Code § 17701.04(b)). Do not attempt to form a "PLLC" for a licensed profession in California — the Secretary of State will not register an LLC to provide professional services. Licensed professionals use a Professional Corporation (PC) under the Moscone-Knox Act. For certain professions (notably law, accountancy, and architecture), a registered limited liability partnership (RLLP) is an alternative limited-liability vehicle; confirm eligibility with your licensing board.

Factor Professional Corporation (PC) — Moscone-Knox Act
Owners called Shareholders
Ownership limited to licensed persons Yes — licensed persons only (§ 13406); limited related-profession minority allowed for designated PCs, capped at 49% (§ 13401.5)
Single profession Yes — single profession, except multidisciplinary minority ownership authorized by § 13401.5
Certificate of registration Required for some professions; not required for many boards listed in § 13401(b)
Articles must declare PC status Yes — § 13404
Share transfer void if to non-licensed Yes — § 13407
Federal tax default C corporation (S-election available)

About This Template

Starting a business means choosing a legal structure and filing the right paperwork to make it official. LLCs, corporations, and partnerships each have different tax, liability, and governance rules, and each state has its own filing forms and fees. Getting these documents right at the start protects your personal assets, sets up clean ownership terms between founders, and avoids expensive fixes later.

Important Notice
