The short version
If your corporation or LLC was formed in another state but transacts business in California, the state generally expects you to register (often called foreign qualification), and registration requires a California agent for service of process. Corpgate, Inc. serves as that agent for out-of-state companies every day; many of our clients are exactly this situation.
When registration is required
California casts a wide net on "transacting intrastate business." Common triggers include an office, warehouse, or employees in California, repeated in-state transactions, and meeting revenue or property thresholds under state tax law. Whether your specific activity crosses the line is a legal and tax question worth an hour of professional advice; guessing wrong in either direction costs more.
What registering involves
- Register with the Secretary of State: filed online at bizfileonline.sos.ca.gov, with a certificate of good standing from your home state
- Designate a California agent: an individual California resident or a registered 1505 corporate agent like Corpgate, Inc. Your home-state agent cannot cover California
- Stay current afterward: file the Statement of Information on schedule and keep the agent designation continuously maintained
The cost of skipping it
An unregistered company doing California business faces penalties and back obligations, and there's a sharp procedural edge: it generally can't maintain a lawsuit in California courts until it registers. You can be sued here while being unable to effectively sue back.

Foreign qualification questions
What counts as \u201cdoing business\u201d in California?
California interprets it broadly: repeated transactions in the state, employees or offices here, and certain revenue or property thresholds can all trigger it. The specifics matter, so this is a question for your attorney or tax professional; the practical point is that many out-of-state companies with real California activity need to register.
Does my out-of-state company need a California registered agent?
Yes. Registering to transact business in California requires designating and continuously maintaining an agent for service of process located in California, exactly like a domestic entity.
Can my home-state registered agent cover California?
No. Each state requires an agent physically located in that state. Your Delaware or Nevada agent can't receive California service of process; you need a California agent like Corpgate, Inc.
What happens if we do business in California without registering?
Consequences can include penalties, back fees and taxes, and the inability to bring a lawsuit in California courts until the entity registers. An unregistered company can be sued in California; it just can't effectively sue.
Is the process different for corporations and LLCs?
The forms differ but the shape is the same: register with the Secretary of State, designate a California agent, and keep a Statement of Information current going forward.
