Switching the agent for service of process on a California LLC is a single state filing — not a re-formation. Here is the form, the fee, the timing, and the handful of details founders trip over.
California requires every LLC to maintain a agent for service of process on file with the California Secretary of State, Business Programs Division. The agent is the address where lawsuits and official California state mail are delivered. When you change the person or company in that role, the state has to be told within a short window — typically the same year of the change, and in many cases within 30 days.
The handful of common reasons we see founders change California agent for service of processs:
California imposes an $800 minimum annual franchise tax on every LLC, payable to the Franchise Tax Board regardless of income. It is owed every year the LLC exists, even in a loss year, and is separate from the Secretary of State filing fees. LLCs with gross receipts above $250,000 owe an additional gross-receipts fee on top of the $800 minimum.
Confirm the replacement before you remove the current one. The new agent must be a California resident over 18 with a physical California address, or a business entity authorized to transact business in California. If you are using a commercial service, sign up before you file the change so the address you list is real on day one.
California requires the incoming agent for service of process to consent to the appointment. Most online change forms include a consent line the new agent signs (or e-signs). Commercial agent for service of process services handle this automatically.
California's change-of-agent filing is usually called a Statement of Change of Agent for Service of Process or a Change of Agent for Service of Process and/or Office. Submit it through the California Secretary of State portal at sos.ca.gov. You list the LLC's name and California file number, the prior agent and address, the new agent and address, and an effective date.
California typically charges between $10 and $50 to process the change. Online filings are usually paid by credit card on submission. Confirmation arrives by email within a few business days; many states accept the change instantly online.
If you are leaving a paid commercial agent, send written notice to cancel the renewal. Most services do not refund the unused portion of an annual fee — but they will stop billing in the next cycle. Save the cancellation confirmation with your LLC records.
Online filings with the California Secretary of State are typically processed within 1–5 business days, sometimes the same day. Mail-in filings take longer — plan on 2–4 weeks. Once accepted, the change is reflected in the public California business record and any service of process or state mail goes to the new address from that point forward.
If service of process arrives at the old agent during the gap between filing and acceptance, the old agent is still legally responsible for forwarding it. That is one reason to time the change with at least a brief overlap rather than terminating the prior agent the day before you file.
If you formed your California LLC with us, our Sacramento office is already on file as the agent for service of process for the first year — no change needed. After that, renewal is $119/year, opt-in. If you formed elsewhere and want to switch to us, we file the California change-of-agent form for you and serve as the agent of record from acceptance forward; the state filing fee is paid directly to California.
Either way, the change is straightforward — verify with the California Secretary of State for the current fee and exact form name, then file. Our role is to make sure nothing falls through the gap.
Reservation takes three minutes. A formation specialist in Sacramento handles the rest.
