Before diving into the formation process, it's essential to determine if your business qualifies to operate as an S Corporation in California and meets federal IRS criteria. The IRS has strict rules for S Corp eligibility. Primarily, an S Corp must be a domestic eligible entity (like a corporation or LLC) and cannot have more than 100 shareholders. Shareholders must be US citizens or resident aliens, certain trusts, or estates; partnerships and corporations cannot be shareholders. The entity mus

Step 1: Form Your California LLC or Corporation

The foundational step to setting up an S Corp in California is to first establish a legal business entity with the state. You can choose between forming a Limited Liability Company (LLC) or a traditional Corporation (which can then elect S Corp status). Both options are filed with the California Secretary of State. To form an LLC in California, you'll need to file Articles of Organization (Form LLC-1) with the Secretary of State and pay the required filing fee, which is currently $70. You must

Step 2: Obtain an EIN from the IRS

An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is a unique nine-digit number assigned by the IRS to business entities operating in the United States for tax identification purposes. It's essential for almost all businesses, especially those planning to operate as an S Corp. You will need an EIN to file federal taxes, open a business bank account, hire employees, and apply for business licenses and permits. Applying for an EIN is a free process direct

This is accomplished by filing IRS Form 2553, Election by a Small Business Corporation. This form is the official document that notifies the IRS of your desire to be treated as an S Corp for federal income tax purposes. Form 2553 requires detailed information about your business, including your EIN, business address, the names an
