Your questions, answered

When does my LLC need to register?

Register first, then do business in New Hampshire, if your LLC came from another state.

Doing business unregistered can bring back fees for all the time it was unregistered.

gc.nh.gov · October 2026 · checked

What should I expect to pay to register?

State fee $100; service $199 extra.

Three years of state charges: $300. sos.nh.gov · October 2026 · checked

What gets submitted?

Once the New Hampshire Secretary of State, Corporation Division approves the Application for Registration as a Foreign Limited Liability Company (Form FLLC-1), you're registered.

The filing needs no proof from the home state.

What does staying registered cost?

After registering, count on the annual report: $100.

The state's deadline: April 1.

What's behind the ranking?

It's work taken off your hands (31% of the score), and Mainstay Filing does best there.

Together, cost across three years and work taken off your hands make up 64% of the score.

Your home state wants an agent too, and one account for both states is easier.

Also worth knowing

Mainstay Filing: $497 / New Hampshire Registered Agent.co: $397 / NH Registered Agent.org: $397 (services only).

Can I check these fees?

What the state charges comes from official New Hampshire publications; what services charge comes from what they publish.

Is hiring help required?

No law says you must hire anyone.

Will a company file this for me?

Yes. Every pick prepares and files it, and the state fee is the same no matter who you pick.
