What California law says you need as an agent for service of process

Every LLC must name a registered agent with an in-state street address. An individual agent's California street address goes on the public record. A registered corporate agent's address is already on file with the state and is not repeated in the company's filing.

People and companies allowed: A California resident, or a corporation registered with the Secretary of State as a corporate agent under Corporations Code § 1505. A business cannot act as its own agent for service of process. That comes from Cal. Corp. Code § 17701.13.

The state fees that come back

What keeps coming back is the Statement of Information, at $20 every two years, last day of the LLC's registration-anniversary month, biennially. The penalty is $250. $800 a year minimum LLC tax to the Franchise Tax Board (Form FTB 3522), separate from the Statement of Information.

What decided the order

Upkeep the price covers decided first place in California. It is 26% of the score, and the other criteria are price over three years, renewal terms, fit with the state, plain statement of the state fee.

One agent for any state beat the single-state choice.
