From Maine to California, step by step
We prepare and file Form S&DC-S/N
It lists us as your California agent for service of process, next to your Maine name and formation date. If California wants the Maine certificate, it is ordered first. After approval, your Maine corporation is registered with California.
Will your Maine name work for California?
If another California company uses the Maine name, an alternate name is allowed. California can hold a name for 60 days for $10 before you file.
Agents: California and Maine
California calls it an agent for service of process; Maine says registered agent. Your current registered agent stays for Maine; ours takes California's papers and notices.
Yearly filings: California and Maine
Each year your corporation files Maine's Annual Report ($85) and California's Statement of Information (Form SI-550) ($25). With our $149 agent for service of process renewal, Maine plus California comes to $259 a year. Both states' filings stay current side by side.
LLC or corporation, Maine to California
