From Connecticut to New Hampshire, step by step
We prepare and file Form 40
It lists us as your New Hampshire registered agent, next to your Connecticut name and formation date. If New Hampshire wants the Connecticut certificate, it is ordered first. After approval, your Connecticut corporation is registered with New Hampshire.
Will your Connecticut name work for New Hampshire?
We search New Hampshire's records for Connecticut's name on file before anything is filed.
Agents: New Hampshire and Connecticut
Connecticut and New Hampshire both call it a registered agent. Your current registered agent stays for Connecticut; ours takes New Hampshire's papers and notices.
Yearly filings: New Hampshire and Connecticut
Each year your corporation files Connecticut's Annual Report ($150) and New Hampshire's Annual Report ($100). With our $149 registered agent renewal, Connecticut plus New Hampshire comes to $399 a year. The new registration does not replace any home-state filing.
LLC or corporation, Connecticut to New Hampshire
An LLC formed in Connecticut files Form FLLC-1 with New Hampshire ($102 in state fees, the same; no home-state certificate is needed). After that come Connecticut's Annual Report ($80) and New Hampshire's Annual Report ($100). See the LLC filing.
The other way: New Hampshire into Connecticut
A corporation formed in New Hampshire that registers with Connecticut files Connecticut's registration (no form number) with $385 in state fees. See that filing.

Does New Hampshire require a registered agent?

Connecticut companies leave by filing an Application for Certificate of Withdrawal of a For-Profit Foreign Corporation; until then, New Hampshire's report stays due alongside Connecticut's filings.
