Are you a professional looking to start your corporation in California?
In California, professionals such as lawyers, doctors, and accountants cannot form LLCs or standard corporations to operate their practices. Instead, they must establish a Professional Corporation (PC), which complies with state regulations and may be taxed as an S-Corporation to maximize tax benefits.
Each profession has unique requirements when forming a Professional Corporation. If done incorrectly, the Secretary of State may reject it, risking you to lawsuits and fines. You may even face discipline from the professional regulatory board.
Here’s a step-by-step guide on what a California Professional Corporation is and how to form it. We can help you with our Done-For-You Professional Corporation Registration Service.

What is a California Professional Corporation?
A California Professional Corporation (PC) is a specialized business entity created specifically for professionals like lawyers, doctors, accountants, and others who are required to have a state-issued license to practice. Unlike traditional corporations or LLCs, a PC allows licensed individuals to offer services under the legal protections of a corporation, while ensuring compliance with state regulations governing their profession.
Forming a Professional Corporation (PC) is essential in California, as many professionals are prohibited from using an LLC or standard corporation for their business.
According to the Moscone Knox Professional Corporation Act, you can only form California professional corporations for PROFESSIONAL services within a single profession requiring a license. For more info, click HERE.
A California Professional corporation can only lawfully render professional services through employees who are licensed to perform such services by the State.
The owner of the corporation usually requires a license for their profession. The State usually regulates them in some way.
The articles of incorporation of a professional service corporation must contain a specific statement that the corporation is a professional corporation within the Moscone Knox Professional Corporation Act.
No professional service corporation can render professional services in this California without a currently effective certificate of registration issued by the governmental agency regulating the profession in which such corporation is or proposes to be engaged.
Why Be a Professional Corporation Taxed as an S-Corporation?
Professional corporations default to C-Corporation status unless an S-Corporation election is made. This choice impacts your tax obligations, so it’s crucial to decide early on whether to file for S-Corp status based on your specific business and tax needs.
You SHOULD elect to have your corporation to be taxed as an S-Corporation. More on this below….
Requirements of a California Professional Corporation

Under the California Business and Professions Code, only individuals who hold valid professional licenses for their respective fields may serve as shareholders in a Professional Corporation.
This ensures that all ownership is directly tied to qualified professionals. If you’re forming a Professional Corporation, each shareholder must hold a license for the specific profession that the corporation is engaged in, aligning with state regulations to prevent unqualified ownership.
Name Requirements of Professional Corporations
Choosing a name for your Professional Corporation in California comes with specific rules that vary by profession. Your corporate name must meet the guidelines set by both the California Secretary of State and your professional licensing board. It should clearly indicate the type of professional services offered and often must include specific terms like “Professional Corporation” or “PC.”
Additionally, it’s important to ensure the name is distinguishable from any existing businesses registered with the Secretary of State.
It is essential to check the name availability with the California Secretary. It should be DISTINGUISHABLE from any other businesses on the California Secretary of State.
Each specific profession has its own name requirement, like particular words. Lastly, each domain has special suffix requirements; psychology will accept “P.C.” as the corporate ending.
Which Professions Need to Form a California Professional Corporation?
Unlike many other states, California does not allow professionals to form a registered limited liability company or professional limited liability company. In California, professionals must include either a professional services corporation or a registered limited liability partnership.
A professional service corporation qualified to render professional services in California must acquire all of the shares of a shareholder who is disqualified from rendering professional services in California or of a deceased shareholder licensed to render professional on their date of death services in this state.
Keep in mind that before forming a professional corporation, you should consider whether forming a professional service corporation (as opposed to other possible business entities such as LLC, LLP, etc.) is the best fit for your business.
A group of individuals interested in establishing a business together may have differing views on operating the company.
It may be worth it in the long run when you consider the necessity of protecting your personal and corporate assets and the potential profitability of your business.
To conclude, you should determine your particular business needs before forming a professional service corporation.
California Professional corporations formed outside California but intend to do business in the state must register with the California Secretary of State.
A Statement and Designation by Foreign Professional Corporation form must be completed and filed with the associated fees.
Foreign professional corporations must file a Certificate of Good Standing from the state where they were formed.

Can a Professional Corporation Be an S Corporation?

es, a Professional Corporation can choose to be taxed as an S Corporation, and in most cases, this is a recommended strategy for maximizing tax benefits. By electing S Corporation status, the company can avoid the “double taxation” that C Corporations face, where both the corporation and the individual owners are taxed on income.
Instead, an S Corporation allows profits (and certain losses) to pass directly to the shareholders’ individual tax returns, thus avoiding corporate tax rates and potentially reducing your overall tax burden.
You may avoid self-employment tax, saving you around 15.3%. You SHOULD have a business lawyer to prepare and file your Form 2553 with the IRS to get taxed as an S Corporation.
Unless you make this tax election and properly file the paperwork, your professional service corporation will default taxed as a C Corporation.
Email me at sam@mollaeilaw.com for any questions about the S-Corp election process.
S Corporation Advantages for Professional Corporations
Enjoy the following:
• Avoid self-employment tax
• Avoid double taxation
• Being taxed as a pass-through entity like LLCs
• Pass losses from the business to offset your income tax liability

Can I Form an LLC For My Professional Business?

Most states allow professionals to open Professional LLC (PLLCs) to practice their professions, but California does NOT permit licensed professionals to form any LLC.
California Revised Uniform Limited Liability Company Act rules that companies offering professional services must be registered as Professional Corporations or Limited Liability Companies.
Can A Disqualified Person Form A Professional Corporation?
If you’re licensed but disqualified, you cannot create a professional service corporation or be its director, officer, or shareholder.
Below is the guide to starting your professional corporation.
Step 1: Define Your Corporation
You may ask first:
- What legal entity my professional corporation will be considered?
- What is the tax regime for my entity in California?
While most states allow professionals to open PLLCs, California is otherwise. California Revised Uniform Limited Liability Company Act requires your company to register as a Corporation for a professional service. Source
By default, your corporation will be taxed as a C-Corp. Alternatively, you may opt for a tax election so that it will be taxed as an S-Corp instead.
Your Professional Service Corporation can and should be an S-Corp. by filing Form 2553 with the IRS through a business lawyer. Your company needs an identity.
You need a name, an address, a strategic location, and a clear business goal.
To legally form Your Professional Corporation in California, the first step is to file Articles of Incorporation with the Secretary of State. This document must include the corporation’s name, address, purpose, and the names of shareholders and directors, along with other critical details.
This document must include key information like your corporation’s name, physical business address, number of authorized shares, and the primary purpose of your corporation (which should reference the type of professional services you provide).
Additionally, ensure you designate an agent for service of process, who will receive any legal documents on behalf of your corporation.
The requirements for each category depend on the professional service your corporation specializes in, and failure to comply may result in fines or rejection.
- The corporation’s name must be distinguishable from any other business. Check it here.
- Each profession will have its own name requirement.
- It should have special suffix requirements as the corporate ending.
Follow the instructions provided with the form for completing and filing your articles of incorporation.

Step 2: Appoint Directors
Let’s talk about who’s in charge. Appoint the directors of your corporation.
A California Professional Corporation is required to appoint at least three directors, unless there are fewer than three shareholders in the company. Each director will be responsible for overseeing the corporation’s operations and governance.
This structure ensures that the corporation meets its legal obligations under California Corporations Code section 13403. Be sure to document this decision in your corporate minutes, as these are required for proper corporate governance.
A professional service corporation is a corporation for business owners who work in specialized fields. In California, professional corporations are established under the Moscone-Knox Professional Corporation Act, California Corporations Code section 13400-13410.
Step 3: Draft Corporate Bylaws
Create detailed corporate bylaws that establish the rules and guidelines for your Professional Corporation’s day-to-day operations.
Corporate bylaws are essential for outlining how the corporation will be managed.
These bylaws are critical for ensuring the smooth operation of your corporation and must comply with state law. Having thorough and clear bylaws will also protect your corporation in the event of a legal dispute or audit.
Professional Corporations should use specific language in their bylaws and abide by certain criteria and standards. They need a business lawyer’s advice in drafting laws.
Step 4: Get Your EIN
Back to taxes! Much like a Social Security number, an EIN (Employer Identification Number), or Tax ID, is a reference number that’s unique to your company.
You need an EIN when:
- Hiring employees;
- Filing federal taxes;
- Applying for local permits/licenses;
- Applying for loans/federal financial assistance programs.
You can do this online, by fax, or post, provided you have a Social Security Number (SSN). Learn more on the IRS website here.
Step 5: File a Statement of Information
Every professional corporation must file a Statement of Information with the California Secretary of State within 90 days of formation.
This document includes updated details about the corporation’s officers, directors, and agent of process, and it must be renewed annually.
Be careful with the deadlines and remember to resubmit it yearly. It must be filed within the first 90 days of registration. Then, file it annually if there are changes. Use this link to register online.
Step 6: File Form 2553 for S-Corporation Tax Election
To elect S-Corporation status for your professional corporation, file IRS Form 2553 within 75 days of incorporation. This allows for pass-through taxation, avoiding the double taxation that applies to C-Corporations.

Step 7: Pay Your Taxes and Fees to the California Franchise Board
All professional corporations in California are required to pay a minimum annual tax of $800 to the California Franchise Tax Board (FTB), starting in the first year of formation. Your first payment is due by the 15th day of the fourth month after filing, and subsequent payments are due each April 15th. Failing to make this payment on time can result in penalties, so it’s crucial to stay on top of your corporation’s tax obligations. Consulting a tax professional can help ensure you meet all requirements and avoid unnecessary fines.
Your first Franchise Tax payment is due by the 15th day of the 4th month after filing. Then, every year after your first payment, it is due by April 15th, and failure to pay before the deadline can have serious consequences.
Hire an accountant to help you out. You can contact the California Franchise Tax Board (FTB) for any taxation-related questions.
Bonus Material: Consult the FTB website for more information.
Step 8: Register With the EDD
Do you plan on hiring any employees? Source
Register as an employer with the California Employment Development Department (EDD). You have to pay payroll tax even if your corporation only has a president without other employees and is paid over $100.
Register your EDD payroll tax account number here.
9. Apply for Local Business Registration and Licenses
Get your corporation registered with the city or county where you’re operating business. Get all the federal and local permits to work legally. The requirements can vary, depending on your business location and services.
