An LLC formed outside New Hampshire that does business inside New Hampshire must register as a foreign LLC and appoint a New Hampshire registered agent. Here is what the requirement covers, when it is triggered, and what foreign qualification looks like in New Hampshire.
"Foreign" in New Hampshire business law does not mean international. It means out-of-state. A Delaware LLC operating in New Hampshire is, from New Hampshire's perspective, a foreign LLC — even though both are U.S. entities. New Hampshire requires foreign LLCs that transact business inside the state to register with the New Hampshire Department of State, Corporation Division and to designate a New Hampshire registered agent with a physical New Hampshire address.
The registered agent requirement is the same as for New Hampshire-formed LLCs: a person or company with a real New Hampshire street address, available during business hours, who agrees to accept service of process and state correspondence on behalf of your LLC. P.O. boxes do not count. Out-of-state addresses do not count. The whole point is that New Hampshire courts and the New Hampshire Corporation Division need a reliable in-state delivery point.
Annual report $100 ($102 online) due April 1.
New Hampshire does not require every LLC that touches the state to register. Occasional sales to New Hampshire customers from out of state generally do not trigger the rule. The threshold is "transacting business" — a phrase New Hampshire courts and the New Hampshire Corporation Division interpret based on the facts. The activities that almost always trigger it:
Activities that usually do not trigger it: maintaining a bank account in New Hampshire, holding a single isolated meeting, defending a lawsuit, or shipping product to New Hampshire customers from another state. New Hampshire statutes list specific safe harbors; verify with the New Hampshire Corporation Division or counsel if the call is close.
New Hampshire requires a Certificate of Good Standing (sometimes called a Certificate of Existence) from the home state, dated within 30 to 90 days. Order it from the home Secretary of State before filing in New Hampshire.
If your home-state name is already taken in New Hampshire, you will file under an assumed or alternate name for New Hampshire purposes. New Hampshire runs the distinguishability check during the foreign qualification filing.
List the agent's name and New Hampshire street address on the application. Our Concord office serves as the agent for foreign-qualified LLCs the same way it does for New Hampshire-formed LLCs.
Submit the foreign qualification application (sometimes called Application for Certificate of Authority) through the New Hampshire Corporation Division at sos.nh.gov. Filing fees vary by state — verify with the New Hampshire Corporation Division for the current New Hampshire amount.
Once registered, your foreign LLC owes the same New Hampshire annual report and any state-specific tax filings that domestic LLCs do. The home-state filings continue separately.
Operating an out-of-state LLC in New Hampshire without registering carries real consequences. New Hampshire typically:
None of these are guaranteed in every fact pattern, but they are the typical exposure. Foreign qualification is one of the most common compliance gaps we see — and one of the cheaper ones to fix once you are aware of it.
For New Hampshire-formed LLCs, the registered agent is one piece of a familiar setup. For foreign LLCs, the agent is often the LLC's only physical presence in New Hampshire — and the only address through which the state can reach you. Service of process delivered to the registered agent is legally valid, even if no one tells you about it for days. Choose an agent that scans and forwards mail the same business day.
Our Concord office handles foreign-qualified LLCs the same way it handles domestic ones: scanned service of process within the hour during business hours, New Hampshire state correspondence forwarded by email, and annual report reminders 60, 30, and 7 days before the deadline. Verify with the New Hampshire Corporation Division for the current foreign qualification fee and processing time.
