How to Change Your LLC Name in California


Q: How do I change the name of my LLC?

Thank you to a customer from California for that great question! If you want to change your LLC name in California, you’ll need to file a California Certificate of Amendment with the Secretary of State and contact the IRS. You’ll also need to update your business name wherever you use it, including on your business license, website, and social media. We’ll take you step-by-step through the process.

1. Choose a new business name

Every California LLC name must follow the state’s naming laws. Per CA Corp Code § 17701.08, an LLC name must not:

  • Use words reserved for financial institutions or insurance companies, such as “bank,” “insurer,” “trust,” etc.
  • Contain the words “corporation,” “incorporated,” or any abbreviation of those words.

Additionally, your name must contain the words “limited liability company” or an abbreviation, such as “LLC.”
