To form an LLC in New Mexico, you file Articles of Organization with the Secretary of State for a $50 fee, after choosing a compliant name and appointing an in-state registered agent. Most filings are approved within one to three business days through the online portal at enterprise.sos.nm.gov.1Secretary of State. New Mexico Secretary of State Online Filing System After formation, you’ll need a federal EIN and a state Business Tax Identification Number, and depending on what you do, possibly industry or local licenses. New Mexico is one of a handful of states that does not require LLCs to file annual reports, which keeps ongoing paperwork and costs lower than most neighbors.
Pick a Name That Meets State Rules
Your LLC name must include “limited liability company” or “limited company,” or an abbreviation such as “LLC,” “L.L.C.,” “LC,” or “L.C.” You can shorten “limited” to “ltd.” and “company” to “co.”2Justia. New Mexico Code 53-19-3 – Name The name has to be distinguishable from every existing LLC, limited partnership, or corporation already on file in New Mexico, including foreign entities registered to do business here.
Check availability through the Secretary of State’s online portal before you file. If you’ve landed on a name but aren’t ready to file formation paperwork, you can reserve it for 120 days for roughly $20. Reservations cannot be renewed, so treat the window as a firm deadline.
Appoint a Registered Agent
Every New Mexico LLC must designate a registered agent to receive legal documents and official correspondence. The agent can be an individual who lives in New Mexico or a business entity authorized to operate here. Either way, the agent needs a physical street address in the state. A P.O. box does not qualify.3Justia. New Mexico Code 53-19-5 – Registered Office and Registered Agent
You can act as your own agent if you have a qualifying address, which saves money but requires you to be present during business hours to accept service of process. Commercial registered agent services typically charge $100 to $150 per year and handle it for you, which is worth considering if you work remotely or travel often.
File the Articles of Organization
The Articles of Organization is the document that officially creates your LLC. You file it through the Secretary of State’s online filing system, creating an account with an email and password before you start. One or more people can form the LLC, and the organizers do not need to be members.4Justia. New Mexico Code 53-19-7 – Formation
Have the following ready before you start the form:5New Mexico Secretary of State. Articles of Organization Form
- The LLC name, meeting the naming rules above.
- Duration, either perpetual (the default) or a set dissolution date.
- The registered agent’s full name and New Mexico street address, plus their signed acceptance.
- A physical principal place of business, and a mailing address if different.
- Whether the LLC will be member-managed or manager-managed.
The management choice matters more than people realize. The statute treats member management as the default, meaning all members share management authority equally unless the Articles of Organization explicitly opt for manager management.6Justia. New Mexico Code 53-19-15 – Management by Members or Managers For a single-member LLC the distinction is academic. For a multi-member company with passive investors, manager-managed is usually the better fit.
The $50 filing fee is payable by credit card or electronic check through the online portal. Most filings are processed within one to three business days, and the Certificate of Organization arrives by email once approved.
Write an Operating Agreement
New Mexico does not require you to file an operating agreement with the state, but skipping it is one of the most common mistakes new owners make. The operating agreement is the internal contract that governs how the company actually runs: ownership percentages, profit distribution, voting rights, what happens if a member wants out, and the procedure for dissolving.
Without one, disputes fall back to state defaults, which may not reflect what the members intended. Banks sometimes ask for a copy when you open a business account, and the document is useful for showing a court that you treat the LLC as a separate entity from yourself. Even single-member LLCs benefit from a short agreement documenting the separation between personal and company finances, since that separation is what protects your liability shield.
Get an EIN and Register for Gross Receipts Tax
Most LLCs need a federal Employer Identification Number from the IRS. You’ll use it to open a business bank account, file federal taxes, and hire employees. The application is free, takes a few minutes on the IRS website, and the number is issued immediately upon approval.7Internal Revenue Service. Get an Employer Identification Number Watch out for third-party sites that charge for this service. The IRS never charges for an EIN.
You also need to register with the New Mexico Taxation and Revenue Department for a Business Tax Identification Number, which is used to report and pay Gross Receipts Tax. New Mexico imposes this tax on the total value of transactions conducted in the state. Registration is free. You can apply online through the department’s Taxpayer Access Point at tap.state.nm.us or submit a paper application to a district tax office.8NM Taxation & Revenue Department. Who Must Register a Business Any entity other than a sole proprietorship must have a federal EIN before applying, so get that first.
Consider an S Corporation Election
By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC is taxed as a partnership. Both pass income through to the owners’ personal returns. Some owners reduce their self-employment tax burden by electing to have the LLC taxed as an S corporation instead.
You make the election by filing IRS Form 2553 no later than two months and 15 days after the beginning of the tax year in which you want it to take effect.9Internal Revenue Service. Instructions for Form 2553 For a new LLC, that clock starts when you file your Articles of Organization, acquire assets, or begin doing business, whichever comes first. Miss the deadline and the election waits until the following tax year unless you qualify for late-election relief.
S corporation treatment isn’t right for every LLC. It requires paying yourself a reasonable salary with payroll taxes, and it works best when profits run well above what a reasonable salary would be. Talk to a tax professional before making the election. It’s easy to file and difficult to undo.
Check Licenses and Local Permits
New Mexico has no single statewide business license that every LLC must obtain. Whether you need one depends on what your business does. The Regulation and Licensing Department oversees licensing for 35 industries and professions, with separate divisions covering construction, financial institutions, alcohol, cannabis, and securities, among others.10New Mexico Regulation and Licensing Department.

Cities and counties often impose their own registration requirements on top of state licensing. Rules vary by municipality, and industries like food service, lodging, and businesses that produce air emissions tend to face extra local permitting. Check with your city or county clerk’s office for what applies to your specific location.
If You’ll Hire Employees
Hiring triggers additional obligations. You must register for unemployment insurance tax through the New Mexico Department of Workforce Solutions. New employers register through the department’s online self-service system and receive an Employer Account Number used for all interactions with the agency. For 2026, the taxable wage base is $34,800 per employee.11New Mexico Department of Workforce Solutions. Unemployment Insurance Tax Information
You also must report every new and rehired employee to the New Mexico New Hire Directory within 20 days of their hire date. This applies to full-time, part-time, and temporary workers alike, and reporting is done through the directory’s online portal.12New Mexico New Hire Directory. New Mexico New Hire Directory Beyond those state requirements, you’ll handle federal payroll tax withholding and carry workers’ compensation insurance.
What Ongoing Compliance Looks Like
New Mexico is unusually light on recurring LLC paperwork. The state does not require LLCs to file annual reports or pay an annual franchise tax to the Secretary of State. That sets it apart from most states, where annual report fees and filing deadlines create regular administrative work.
That doesn’t mean you can forget about the LLC after formation. Your registered agent information must stay current with the Secretary of State. If your agent changes, you have to file an update. You also need to keep up with Gross Receipts Tax filings and any federal returns the LLC owes.
Federal beneficial ownership reporting is also worth knowing about. In March 2025, FinCEN issued an interim final rule that exempts all entities created in the United States from Beneficial Ownership Information reporting requirements. Only foreign companies registered to do business in a U.S. state must now file.13Financial Crimes Enforcement Network. FinCEN Removes Beneficial Ownership Reporting Requirements for US Companies and US Persons If you’re forming a domestic New Mexico LLC, you currently have no BOI filing obligation. FinCEN has indicated it intends to finalize this through further rulemaking, so the position could shift, but as of 2026 domestic LLCs are exempt.
