The walkthrough, stage by stage

  1. Stage 1

    The New Mexico rule in plain terms

    Every LLC must name a registered agent with an in-state street address.

    Check it yourself: Official page: nmonesource.com (viewed October 2026)

  2. Stage 2

    Who can do this

    A New Mexico resident, or a corporation, LLC or partnership formed in New Mexico or authorized there whose place of business is the registered office. Legal basis: NMSA 1978, § 53-19-5.

  3. Stage 3

    Use an office address that qualifies

    The address has to be a street address in New Mexico. P.O. boxes are not accepted.

    Each of our picks supplies a New Mexico office address.

  4. Stage 4

    Serve yourself or bring in a pro

    Qualify and you may serve yourself. A professional from our list runs $99 to $149 per year.

  5. Stage 5

    Record the appointment

    A New Mexico LLC that is just being formed names its agent on the Articles of Organization. Any later switch is its own filing at the New Mexico Secretary of State.

    Check it yourself: Official page: nmonesource.com (viewed October 2026)

  6. Stage 6

    Check the record each year

    No report is due, so your single job is to keep the registered agent appointment up to date.
