From Illinois to Maine, step by step
We prepare and file Form MBCA-12
It lists us as your Maine registered agent, next to your Illinois name and formation date. If Maine wants the Illinois certificate, it is ordered first. Once Maine approves it, the Illinois company can do business there.
Your Illinois name and Maine's rules
We search Maine's records for Illinois's name on file before anything is filed.
Your Maine agent and the Illinois one
Illinois and Maine both call it a registered agent. Your current registered agent stays for Illinois; ours takes Maine's papers and notices.
Staying in good standing in Illinois and Maine
Each year your corporation files Illinois's Annual Report (Form BCA 14.05) ($75) and Maine's Annual Report ($150). With our $149 registered agent renewal, Illinois plus Maine comes to $374 a year. The new registration does not replace any home-state filing.
LLC or corporation, Illinois to Maine
An LLC formed in Illinois files Form MLLC-12 with Maine ($250 in state fees and the $50 required expedite, the same, plus the Certificate of Good Standing ($25)). After that come Illinois's Limited Liability Company Annual Report (Form LLC-50.1) ($75) and Maine's Annual Report ($150). See the LLC filing.
