How a New Mexico agent is set up

  1. Section 1

    Read the New Mexico requirement

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

    Reference: nmonesource.com (edition of October 2026)

  2. Section 2

    Identify eligible agents

    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. Authority: NMSA 1978, § 53-19-5.

  3. Section 3

    The address rule

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

    Each recommended service provides a New Mexico office address.

  4. Section 4

    Serve as your own agent or hire one

    A qualified owner can be the agent. Those who prefer not to can pay $99 to $149 a year to a recommended agent.

  5. Section 5

    Make the agent a matter of public record

    The agent is named when the Articles of Organization is filed, and a later change is a separate filing with the New Mexico Secretary of State.

    Reference: nmonesource.com (edition of October 2026)

  6. Section 6

    Review the record each year

    With no report due, the single task is keeping the registered agent appointment current.
