Formation in order

  1. Stage 1

    Search for your name before you fall in love with it

    Do your name search at the New Mexico Secretary of State. Finding a clash now beats a rejected New Mexico filing later.

    See whether the web address is open while you are at it.

  2. Stage 2

    Get a registered agent in place

    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.

    Our recommended services all work as a registered agent.

  3. Stage 3

    Who does the paperwork?

    You could file for $50 and be done, or add $199 and let one of our picks handle it.

  4. Stage 4

    Your next job is the Articles of Organization

    Fill out the Articles of Organization, add $50 and send it all to the New Mexico Secretary of State (NMSA 1978, § 53-19-7).

  5. Stage 5

    Pick up the EIN

    When New Mexico approves the LLC, go to the IRS for an Employer Identification Number; your bank and any payroll service will ask for it. Mainstay Filing prepares the EIN application inside its package.

  6. Stage 6

    Write an operating agreement

    It spells out shares, voting and what happens if someone leaves. It stays private.

  7. Stage 7

    Mark the dates that come back around

    New Mexico has no repeating LLC report, so all you have to maintain is a registered agent.
