How to Form an S Corp in California | Lovie — US Company Formation

Forming an S Corporation (S Corp) in California offers potential tax advantages for eligible businesses, primarily by allowing profits and losses to be passed through directly to the owners' personal income without being subject to corporate tax rates. This structure can significantly reduce the overall tax burden compared to a C Corporation. However, the process involves specific state and federal requirements. Understanding these steps is crucial for any California-based business considering this entity type. Lovie specializes in simplifying business formations across all 50 states, including the intricacies of establishing an S Corp in the Golden State. This guide will walk you through the essential steps to form an S Corp in California. We’ll cover everything from initial business structure decisions and state filings with the California Secretary of State to making the crucial S Corp election with the IRS. By following these guidelines, you can ensure your business is compliant and positioned for success. Remember, while this guide provides comprehensive information, consulting with a tax professional or legal advisor is always recommended for personalized advice.

Understanding S Corp Eligibility and Benefits in California

Before diving into the formation process, it's vital to understand what an S Corp is and if your business qualifies. An S Corp is not a business structure itself, but rather a tax election made with the IRS. To qualify for S Corp status, your business must first be formed as a domestic eligible entity, such as a C Corporation or an LLC, in California. Key eligibility requirements set by the IRS include having no more than 100 shareholders, all of whom must be U.S. citizens or resident aliens, ce

Step 1: Form Your California LLC or C Corporation

The foundational step to becoming an S Corp in California is to first establish your business as either a Limited Liability Company (LLC) or a C Corporation with the California Secretary of State. You cannot directly form an S Corp; it's a tax designation applied to an existing eligible entity. For an LLC, you will file Articles of Organization with the Secretary of State. This document requires basic information about your LLC, such as its name, the street address of its principal office, and t

Pay the $70 filing fee to the California Secretary of State.
Appoint a registered agent with a physical California address.
File the initial Statement of Information within 90 days ($20 fee).

Step 2: Obtain an Employer Identification Number (EIN)

Once your business is officially formed with the California Secretary of State, the next critical step is to obtain an Employer Identification Number (EIN) from the Internal Revenue Service (IRS). An EIN, also known as a Federal Tax Identification Number, is a unique nine-digit number assigned to business entities operating in the United States for tax purposes. It's essentially the Social Security number for your business. You will need an EIN to open a business bank account, file federal taxes

Step 3: Make the IRS S Corp Election (Form 2553)

With your California entity formed and your EIN secured, the most crucial step is to formally elect S Corp status with the IRS. This is done by filing IRS Form 2553, Election by a Small Business Corporation. This form is used by both C Corporations and LLCs (that have elected to be taxed as a C Corp or partnership) to elect to be treated as an S Corp. The election must be made by a corporation that meets the eligibility requirements previously discussed. The form requires detailed information ab

Missing the deadline may require filing late with IRS approval.
The IRS must approve your Form 2553 for S Corp status.

Step 4: Make the California State S Corp Election

Successfully electing S Corp status with the IRS does not automatically grant you S Corp status for California state tax purposes. California has its own separate election process that must be followed. To elect S Corp status in California, you need to file Form 3893, Election by a Small Business Corporation (or substantially similar wording depending on current FTB forms), with the California Franchise Tax Board (FTB). This state-level election is crucial because California may tax S Corps diff

Consult FTB guidelines or a tax professional for CA-specific rules.

Ongoing Compliance for California S Corps

Forming an S Corp in California involves more than just filing the initial paperwork and elections. Ongoing compliance is essential to maintain your S Corp status and avoid penalties. One of the most significant ongoing requirements is the Franchise Tax. California imposes an annual minimum franchise tax of $800 on LLCs, C Corps, and S Corps, payable to the Franchise Tax Board. This tax is due regardless of whether your business is profitable or actively operating. For S Corps, California also i
