Forming an LLC in California follows the same basic structure as other states — file formation documents, adopt an operating agreement, get an EIN — but California layers on a few requirements that catch founders coming from other states off guard.
The annual franchise tax applies regardless of income
California imposes an annual minimum franchise tax on LLCs, due even in a year with no revenue or a net loss — a flat cost of doing business in the state that many first-time founders don't budget for.
The Statement of Information requirement
Beyond the initial Articles of Organization, California requires a Statement of Information within a set window after formation, and periodically afterward — a recurring filing separate from the annual tax that's easy to miss if you're used to a state with fewer ongoing requirements.
Operating agreement isn't filed, but it's still required
California technically requires LLCs to have a written operating agreement, even though it isn't filed with the state — meaning it's easy to overlook since there's no state deadline forcing you to create one, despite the legal requirement to have it.
Getting the sequencing right
Between the franchise tax, the Statement of Information, and the operating agreement requirement, California rewards founders who get their formation paperwork sequenced correctly from the start rather than treating it as a single one-time filing.
