The walkthrough, stage by stage

  1. Stage 1

    When registration is a must

    An LLC formed in another state has to register with New Hampshire before it does business here. An LLC that operates unregistered risks: its contracts can still be enforced (RSA 304-C:180, II(a)) back fees on top

    Check it yourself: We pulled this from gc.nh.gov in October 2026

  2. Stage 2

    Choose your New Hampshire registered agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a physical street address in New Hampshire; filings that list an out-of-state address are not processed. P.O. boxes are not accepted.

    Our picks each fill the registered agent role.

    Check it yourself: We pulled this from gc.nh.gov in October 2026

  3. Stage 3

    Time to send in the Application for Registration as a Foreign Limited Liability Company

    The form and the $100 fee travel together to the New Hampshire Secretary of State, Corporation Division.

    Check it yourself: We pulled this from sos.nh.gov in October 2026

  4. Stage 4

    What comes next

    Send the annual report with $100, April 1 to keep the registration going.

What each stage costs in New Hampshire

StagePaid toAmount
Foreign registrationGoes to the state$100
Annual reportGoes to the state$100
Service fees (optional)The service company$199 at the start
State total across three yearsGoes to the state$300
Whatever goes to New Hampshire is an official fee you can verify on the pages listed below. The three-year row combines the filing, two later reports and a minimum tax where there is one; service prices stay out of it.

Why the list runs this way

Work taken off your desk makes up 32% of the score, and that is where pulled ahead in New Hampshire.

The company belongs to one state and works in a second, so one provider for both is the better fit.
