How to Apply for an EIN in California

The EIN step itself

One federal form, one agency, the same options wherever the business sits: online, fax, mail, or the international phone line. The method decides the timeline, not the state. Every method and what it actually takes covers that in full, and it applies to California unchanged.

What California needs first

Form your entity with the California Secretary of State (bizfile Online) before applying. The IRS asks for the legal name and formation date exactly as the state recorded them, and a mismatch is one of the common causes of a rejected application.

California issues a entity number. It identifies your company in state records and is not a tax ID. It cannot be used where an EIN is asked for, and the IRS has no record of it.

What California requires once you have the EIN

• Register with the California Department of Tax and Fee Administration if you will sell taxable goods, and with the Employment Development Department before your first payroll.
• File a Statement of Information with the Secretary of State shortly after formation, then on the state's ongoing schedule.

What is actually different about California

• California is a community property state. A California LLC owned only by a married couple may be treated as a disregarded entity instead of a partnership, which changes the tax classification on the SS-4 and whether a partnership return is due each year.
• California charges LLCs an annual minimum franchise tax to the Franchise Tax Board whether or not the business earned anything, so a dormant California LLC still has a state obligation that a dormant LLC in most states does not.
• California splits business tax administration across three agencies — the Franchise Tax Board, the Department of Tax and Fee Administration, and the Employment Development Department — rather than the single portal most states use. The EIN is asked for at more than one of them.
