How to Form an LLC in New Mexico

Here are the steps you need to take to start a limited liability company (LLC) in New Mexico.

A limited liability company (LLC for short) is a way to legally structure a business. It combines the limited liability of a corporation with the flexibility and lack of formalities provided by a partnership or sole proprietorship. Any business owner who seeks to limit his or her personal liability for business debts and lawsuits should consider forming an LLC.

Here are the steps you need to take to form an LLC in New Mexico.

  1. Choose a name for your LLC.
  2. Appoint a registered agent.
  3. File Articles of Organization.
  4. Prepare an LLC operating agreement.
  5. Obtain an EIN.

1. Choose a Name for Your LLC

In New Mexico your LLC's name must contain the words "Limited Liability Company" or "Limited Company," or one of the following abbreviations: "LLC," "LC," "L.L.C.," or "L.C." The word "Limited" may be abbreviated as "Ltd." and the word "Company" abbreviated as "Co."

Your LLC’s name must be distinguishable from the names of other business entities already on file with the New Mexico Secretary of State. Names may be checked for availability on the Secretary of State's business name database.

You may reserve a name for 120 days by filing an application for Reservation of Limited Liability Company Name with the New Mexico Secretary of State. The application must be filed by mail. The filing fee is $20.

2. Appoint a Registered Agent

Every New Mexico LLC must have an agent for service of process in the state. This is an individual or business entity that agrees to accept legal papers on the LLC’s behalf if it is sued. The registered agent may be a New Mexico resident or a foreign or domestic business entity authorized to do business in New Mexico. The LLC may not be its own registered agent. The registered agent must have a physical street address in New Mexico.

3. File Articles of Organization

A New Mexico LLC is created by filing Articles of Organization with the New Mexico Secretary of State's office. The articles must include:

  • the LLC's name
  • the effective date of filing the Articles
  • the LLC's period of duration--perpetual or a term of years
  • the LLC's purpose--leave blank if LLC has a general business purpose
  • the name and address of the LLC’s registered agent
  • the LLC's email address and phone number (optional)
  • the address of the LLC' s principal place of business plus mailing address if different
  • whether the LLC will be run by a manager or member
  • whether the LLC has only one member, and
  • the name and contact information for the LLC's organizer.

The articles must be filed online. The filing fee is $50.

Steps to form an LLC

4. Prepare an Operating Agreement

An LLC operating agreement is not required in New Mexico, but is highly advisable. This is an internal document that establishes how your LLC will be run. It sets out the rights and responsibilities of the members and managers, including how the LLC will be managed. It can also help preserve your limited liability by showing that your LLC is truly a separate business entity. In the absence of an operating agreement, state LLC law will govern how your LLC operates. If an operating agreement is created, it need not be filed with the Articles of Organization.

5. Obtain an EIN

If your LLC has more than one member, it must obtain its own IRS Employer Identification Number (EIN), even if it has no employees. If you form a one-member LLC, you must obtain an EIN for it only if it will have employees or you elect to have it taxed as a corporation instead of a sole proprietorship (disregarded entity). You may obtain an EIN by completing an online EIN application on the IRS website. There is no filing fee.
