To form an LLC in New Mexico, you file Articles of Organization with the New Mexico Secretary of State, pay a filing fee of about $50, and wait one to three business days for online approval. Before you file you need a compliant name, a registered agent with a New Mexico street address, and a decision on whether members or managers will run the company. After approval you get a federal EIN, register with the Taxation and Revenue Department, and handle any local or professional licensing your business needs. New Mexico does not require annual reports or annual fees, which keeps ongoing costs low.
Name Your LLC
Your name must include a designator identifying it as a limited liability company. New Mexico accepts “Limited Liability Company,” “Limited Company,” or the abbreviations “LLC,” “L.L.C.,” “LC,” or “L.C.” It also has to be distinguishable from every other LLC, limited partnership, and corporation already registered or authorized in the state.1Justia.

Check availability through the Secretary of State’s online business search. If you have a name you like but aren’t ready to file yet, you can reserve it for 120 days.2Justia. New Mexico Code 53-19-4 – Reservation of Name The reservation fee is set by the Secretary of State, so check the current fee schedule when you file the reservation.
Choose Member-Managed or Manager-Managed
New Mexico lets you run your LLC in one of two ways. The statutory default is member-managed, meaning every owner participates in decisions unless the Articles of Organization say otherwise.3Justia. New Mexico Code 53-19-15 – Management by Members or Managers That fits owners who all want to be actively involved.
A manager-managed LLC puts authority in the hands of one or more designated managers, who can be members or outside professionals. This is the structure to pick when you have passive investors who want ownership without operational responsibility, or when the business is complex enough to justify dedicated managers. You state your choice in the Articles of Organization, so decide before filing.
Appoint a Registered Agent
Every New Mexico LLC must maintain a registered agent and a registered office in the state. The agent accepts legal papers and official notices on the LLC’s behalf. Under state law, the agent must be either an individual who resides in New Mexico or a business entity with a place of business in New Mexico at the same address as the LLC’s registered office.4Justia. New Mexico Code 53-19-5 – Registered Office and Registered Agent
The registered office has to be a physical street address where someone is available during normal business hours. You can be your own agent if you live in New Mexico, but many owners hire a commercial registered agent service. A professional agent is reliably present at the listed address and keeps your home address out of the public record. To change agents later, you file a statement with the Secretary of State that includes the new agent’s name, address, and signed acceptance.4Justia. New Mexico Code 53-19-5 – Registered Office and Registered Agent
File the Articles of Organization
The Articles of Organization is the document that creates your LLC. You file it with the New Mexico Secretary of State, and the form asks for:
- The exact LLC name, including the required designator.
- The name and physical street address of your registered agent, along with their signed consent to serve.
- The principal office address, if different from the registered agent’s.
- Whether the LLC is member-managed or manager-managed.
- The name and address of the organizer filing the document, who does not have to be a member.5Justia. New Mexico Code 53-19-7 – Articles of Organization
- The duration of the LLC. You can pick a fixed end date or leave it perpetual, which is the usual choice.
The form lives in the Secretary of State’s online Business Services portal. Filing online is faster than paper: online submissions typically process in one to three business days, and you get electronic confirmation once approved. The filing fee is roughly $50, paid by credit card in the portal. Review every field before you submit, especially the name and the registered agent details, since errors delay approval.
Put an Operating Agreement in Place
New Mexico does not require you to file an operating agreement with the state, but the statute plainly assumes you will have one. State law defines it as a written agreement governing the LLC’s business and affairs,6Justia. New Mexico Code 53-19-2 – Definitions and requires the LLC to keep a current copy at its principal office along with a record of each member’s capital contributions.7Justia. New Mexico Code 53-19-19 – Records
The operating agreement is where you set the internal rules: how profits and losses are divided, what happens when a member leaves, how votes are counted, and who has authority to sign contracts. Without one, you default to the statute on each of those questions, which rarely matches what the owners actually want. Banks often ask to see the operating agreement when you open a business account, and it becomes decisive if members later disagree. Single-member LLCs benefit from having one too, because it reinforces the separation between the owner and the business.
Get an EIN and Choose a Federal Tax Classification
Once the state approves your LLC, apply for an Employer Identification Number from the IRS. You need an EIN to open a business bank account, hire employees, and file tax returns. The application is free and takes one online session at IRS.gov.8IRS. Get an Employer Identification Number The IRS requires that the LLC already exist at the state level, so wait until you have your Articles of Organization confirmation.
The IRS assigns a default tax classification based on the number of members. A single-member LLC is treated as a disregarded entity, meaning business income is reported on your personal return. A multi-member LLC defaults to partnership taxation, filing an informational return while profits pass through to members.9IRS. Limited Liability Company – Possible Repercussions
You can override the default. An LLC can elect C corporation taxation by filing IRS Form 8832, or S corporation taxation by filing Form 2553.9IRS. Limited Liability Company – Possible Repercussions Talk to a tax professional before making the change, because switching classifications is hard to reverse.
Register for New Mexico Taxes
Anyone doing business in New Mexico must register with the state Taxation and Revenue Department. Registration produces a Business Tax Identification Number, also called a CRS number, which you use to report and pay several state taxes, including gross receipts tax, compensating tax, and wage withholding if you have employees.10New Mexico Taxation and Revenue Department. Who Must Register a Business?
New Mexico’s gross receipts tax is imposed on the business rather than the customer, though most businesses pass it along. Rates vary by location because municipalities add their own increment to the state rate. Register online through the department’s Taxpayer Access Point, or file a paper application by mail or in person at a district tax office.
Handle Local and Professional Licensing
New Mexico does not issue a general statewide business license, but you may still need permits. Many cities and counties require a local business registration, and certain industries need a state-issued professional or occupational license. Contractors, healthcare providers, real estate agents, cosmetologists, and food-service businesses all fall into regulated categories with credential requirements.
Check with the city or county where the LLC operates about local business registration, zoning, and health permits. For state professional licensing, the New Mexico Regulation and Licensing Department oversees most professional boards. Getting these in place before you open avoids fines and shutdowns.
Stay in Good Standing
New Mexico is unusual: it does not require LLCs to file annual reports or pay yearly maintenance fees to the Secretary of State. That is a real cost advantage over states that charge hundreds of dollars a year to keep an LLC active.
You still have work to do. Keep your registered agent information current with the Secretary of State. Maintain accurate financial records and a copy of the operating agreement at the LLC’s principal office, as the statute requires.7Justia. New Mexico Code 53-19-19 – Records File and pay gross receipts tax on time. And keep a separate business bank account, because mixing personal and business funds is one of the fastest ways to lose the liability protection you formed the LLC to get.
Federal Beneficial Ownership Reporting
The Corporate Transparency Act originally required most LLCs to file a Beneficial Ownership Information report with the Financial Crimes Enforcement Network. As of March 2025, FinCEN published a rule exempting all entities formed in the United States from that requirement. Only foreign companies registered to do business in a U.S. state currently have to file.11FinCEN. Beneficial Ownership Information Reporting A New Mexico domestic LLC does not need to file a BOI report under the current rule. This area has been heavily litigated and revised, so check FinCEN’s site periodically in case the requirement is reinstated.
