How registration works in New Hampshire

  1. Task 1

    Is New Hampshire registration needed?

    Vocabulary: a foreign LLC is one formed in a different state. It registers before it does business in New Hampshire. If you skip it: The agreements are not voided (RSA 304-C:180, II(a)). Expect to pay back fees too.

  2. Task 2

    Choose the 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 recommendations cover this role.
