How registration works in New Hampshire

  1. Section 1

    When New Hampshire requires registration

    Key term: foreign LLC. It is an LLC formed in a different state, and New Hampshire asks it to register before operating here. An LLC that operates unregistered faces: agreements already made are not voided (RSA 304-C:180, II(a)) unpaid fees for earlier years

    Reference: See gc.nh.gov; page last consulted October 2026

  2. Section 2

    Arrange a 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.

    Every recommended service provides the registered agent.
