The tasks

  1. Task 1

    Name the company

    Your first assignment is a name search with the New Mexico Secretary of State, so you do not file under something a neighbor already uses.

    Bring two backup names to the search.

  2. Task 2

    Line up a 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.

    The services we rank all supply a registered agent.

  3. Task 3

    Compare doing it alone with paying for help

    With no service the bill is the state's $50 and nothing else. Each of the recommended services adds $199 and does the paperwork for you.

  4. Task 4

    Put together the Articles of Organization

    Send the Articles of Organization to the New Mexico Secretary of State along with $50 to bring the LLC into existence; the legal basis is NMSA 1978, § 53-19-7.

  5. Task 5

    Get an EIN

    State approval first, IRS number second. If you hire Mainstay Filing, the EIN application is taken care of.

  6. Task 6

    Write an operating agreement

    An operating agreement says who owns the New Mexico LLC and how decisions get made. It stays in your records and is not sent to the state.

  7. Task 7

    Stay in good standing in New Mexico

    With no report to send, the registered agent is the only standing duty.

How we ordered the New Mexico picks

Assignments the price completes settled first place in New Mexico. It is worth 31% of the grade, and the other 69% comes from course fee across three years, second-year fee, match with the state syllabus and plain pricing.

Without a report to bundle, the lead over NM Registered Agent.org is thin.
