What is a California Professional Corporation?

A Professional Corporation is a unique corporation providing professional services in California practical instead of the traditional LLC or corporation.

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?

If you don’t want your Professional Service Corporation taxed as an S-Corporation, the default status should be taxed as a C-Corporation. You can use losses to offset income from other sources. You will NOT be required to pay self-employment taxes on any additional corporate profits.

You SHOULD elect to have your corporation to be taxed as an S-Corporation. More on this below….

Requirements of a California Professional Corporation

Requirements of a California Professional Corporation

California Business and Professions Code require that only LICENSED persons be shareholders of a corporation. A shareholder must be licensed in the profession that the corporation is engaged in.

Name Requirements of Professional Corporations

California Professional Corporations have strict name requirements for specific professions. The corporate name must comply with the profession’s rules and any other requirements.

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.

The following professions need to form a Professional Corporation in California:

Eligible professionals must have a degree from any of the following graduate schools:


Can a Professional Corporation Be an S Corporation?

Can a Professional Corporation Be an S Corporation

A professional services corporation can and SHOULD be an S Corporation. S Corporation is a particular corporation that avoids regular C corp.’s double taxation disadvantages. S corps allow profits and some losses to be passed directly to the owners’ income without being subject to corporate tax rates.

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 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?

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.

File the necessary Articles of Incorporation with the California State Secretary with your company’s name, address, address of service, number of shares, and purpose.

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.

Any California Professional Service Corporation must have at least three directors unless less than three shareholders. More details on this are at the California Corporations Code section 13403.

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

Set your corporate bylaws, which are rules defining business operations and addressing issues like the size of the board of directors, their functions, their election, etc. Corporate bylaws are the nervous system of your company.

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

Hang in there! File a statement of Information to ensure your company’s compliance with updated contact information.

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

It is time to file for the corporate election. File an election with the IRS using Form 2553 for the tax treatment of an S-Corp. Do this within the first two months and fifteen days of the tax year when the election takes effect. Otherwise, your election will only be effective from the next tax year.

Step 7: Pay Your Taxes and Fees to the California Franchise Board

Professional corporations need to pay a minimum annual tax of $800 to the California Franchise Tax Board.

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.

Bonus Material: Email me at or contact us here to ensure you meet the requirements.
