How a New Mexico LLC gets formed

  1. Move 1

    Check the name is free

    Name search comes first. Use the records at the New Mexico Secretary of State.

    Have a backup ready.

  2. Move 2

    Who is the registered agent?

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

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

    Hire any one of our picks for this.

  3. Move 3

    DIY or hire help

    Without a service you pay the state $50, nothing more. Any of our picks adds $199 and handles the paperwork.

  4. Move 4

    Send in the Articles of Organization

    Send the Articles of Organization and $50 to the New Mexico Secretary of State. Legal basis: NMSA 1978, § 53-19-7. That brings the LLC into being.

    Where this comes from: Official page: nmonesource.com (October 2026)

  5. Move 5

    Get your EIN

    Once New Mexico approves the LLC, ask the IRS for an EIN. Banks and payroll providers need one. The Mainstay Filing package already includes this move.

  6. Move 6

    Get the owners' deal on paper

    Owners sign it to settle shares, votes and what happens when someone leaves. It is private and never filed.

  7. Move 7

    Keep the LLC active

    New Mexico drops the yearly report; keep the registered agent current and you are covered.
