How California companies register with Connecticut
We prepare and file the registration
It lists us as your Connecticut registered agent, next to your California name and formation date. If Connecticut wants the California certificate, it is ordered first. Once Connecticut approves it, the California company can do business there.
Will your California name work for Connecticut?
We search Connecticut's records for California's name on file before anything is filed.
Your Connecticut agent and the California one
Connecticut calls it a registered agent; California says agent for service of process. Your current agent for service of process stays for California; ours takes Connecticut's papers and notices.
Yearly filings: Connecticut and California
Each year your corporation files California's Statement of Information (Form SI-550) ($25) and Connecticut's Annual Report ($435). With our $149 registered agent renewal, California plus Connecticut comes to $609 a year. The new registration does not replace any home-state filing.
LLC or corporation, California to Connecticut
An LLC formed in California files its own registration with Connecticut ($120 in state fees, plus the Certificate of Status ($5)). After that come California's Statement of Information (Form LLC-12) ($20) and Connecticut's Annual Report ($80). See the LLC filing.
The other way: Connecticut into California
A corporation formed in Connecticut that registers with California files Form S&DC-S/N with $100 in state fees. See that filing.
