Registering costs $100 at the state, plus $199 if you hire help.
Add three years of state fees, registration included, and you get $300. sos.nh.gov, read in October 2026 for this answer
Which form do I file, and with whom?
Send the Application for Registration as a Foreign Limited Liability Company (Form FLLC-1) to the New Hampshire Secretary of State, Corporation Division; the registration is complete when it accepts the filing.
No home-state certificate is requested here, so there is nothing to order before you file.
What do I owe once the LLC is registered?
Down the road there is the annual report, which costs $100.
Timing, in the state's words: April 1.
What put number one on top?
Mainstay Filing does best on chores the price takes care of, which carries 29% of our score.
We weigh five questions: what you pay over three years (33%), chores the price takes care of (29%), answers on the price page (14%), what happens at renewal (13%) and room to add states (11%).
With two states in play, a provider for every state ranks above New Hampshire Registered Agent.co.
The last row is arithmetic, not a state figure: filing fee, plus the reports due in years two and three, plus a minimum tax where one applies. Open-ended costs stay out.
Questions people also ask
Does the state where I formed the LLC still need an agent?
Yes, and the two states do not share a rule book. Mainstay Filing works in both, so one account can cover the home state and this one.
What do the picks cost over three years?
For three years you would pay $497 at Mainstay Filing, $397 at New Hampshire Registered Agent.co, $397 at NH Registered Agent.org, before state fees.
Are the fees official?
State fees come from New Hampshire's official documents, and service fees come from each company's own pricing page. Both carry dates on this page.
Do I have to use a service?
No. What the law asks for is a filing, and it does not say who has to send it.
Will a service file the registration for me?
They do. All the picks prepare and send the registration, so the only thing that changes with your choice is the service fee.
What is the best foreign registration service for New Hampshire?
Mainstay Filing comes first: $199 over the state fee registers you, the registered agent is free in year one and then it is $149 a year. Next are New Hampshire Registered Agent.co and NH Registered Agent.org.
