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 and repeated in-state transactions. Registration and taxes use different tests: the Franchise Tax Board's sales, property and payroll thresholds decide whether you owe California tax, not whether you must register with the Secretary of State, and a company can be caught by either test without the other. 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 bizfile Online, 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. A company that is your agent in another state can serve here only if it also holds a California section 1505 certificate
- 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 cannot bring a lawsuit in California courts on claims from its California business until it registers, though it can still defend a lawsuit brought against it. You can be sued here while being unable to sue back on those claims.

Foreign qualification questions
What counts as "doing business" in California?
California interprets it broadly: repeated transactions in the state and employees or offices here can trigger it. The Franchise Tax Board's revenue, property and payroll thresholds are a separate tax test and do not by themselves decide whether you must register with the Secretary of State. 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?
Only if it also qualifies in California. California requires an agent for service of process who is either an individual California resident or a corporation that holds a California section 1505 certificate. A company that is your agent in Delaware or Nevada can serve in California only if it also holds that certificate; otherwise 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 on claims from its California business until the entity registers. An unregistered company can be sued in California and can still defend itself; it just can't bring those claims.
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.
