Questions to settle

When must an out-of-state LLC register here?

Before an LLC formed elsewhere starts business in New Hampshire, it registers.

Without registration, expect back fees for the unregistered months.

How much should I budget to register?

Doing it yourself costs $100. With a service, add $199.

Over three years the state's fees reach $300, counting any recurring report. verify at sos.nh.gov, as of October 2026

Which form do I file, and with whom?

File the Application for Registration as a Foreign Limited Liability Company (Form FLLC-1) with the New Hampshire Secretary of State, Corporation Division. That single filing registers the LLC.

This state does not ask for a certificate from your home state.

Are there ongoing fees to plan for?

Check the due date: April 1.

Why is the list in this order?

FAQ

Will one agent cover both states?

Both states apply their own rules, so keep an agent at home too. A provider active in every state, such as Mainstay Filing, can cover both.

What is the three-year cost of each?

Three-year costs: Mainstay Filing, $497; New Hampshire Registered Agent.co, $397; NH Registered Agent.org, $397, not counting state fees.

Where do you get the fees?

Official New Hampshire sources back the state side and company pricing backs the service side, all dated.

Does the state require a service?

No. You can file with the state yourself; a service saves time and can act as your agent, but nothing makes you hire one.

Can I hire someone to register?

All of them do, and the state fee stays identical.

Which one do you recommend in New Hampshire?

Mainstay Filing leads on filing jobs included, ahead of New Hampshire Registered Agent.co and NH Registered Agent.org.
