To set up an LLC in New Mexico, you file Articles of Organization online with the Secretary of State for $50, appoint a New Mexico registered agent, get a federal EIN from the IRS, and register with the state’s Taxation and Revenue Department for a Business Tax Identification Number. Processing at the Secretary of State usually takes one to three business days, and New Mexico is one of the few states that requires no annual report and no annual fee to keep the LLC in good standing.
Pick a Name That Meets New Mexico’s Rules
Your company name has to include “Limited Liability Company” or “Limited Company,” or an abbreviation: LLC, LC, L.L.C., or L.C. You can also shorten “Limited” to “Ltd.” and “Company” to “Co.”1Justia. New Mexico Statutes Section 53-19-3 – Name The name must be distinguishable from every LLC, limited partnership, and corporation already on file, plus any name someone else has reserved.
Search the state’s records before you file. The Secretary of State runs a name search through its online portal at enterprise.sos.nm.gov.2New Mexico Secretary of State. Online Filing System Certain words are restricted. Using “Bank,” “Banking,” or other financial terms generally requires authorization from the relevant state agency, so avoid those unless your LLC is actually a licensed financial institution.
Appoint a Registered Agent
Every New Mexico LLC must have a registered agent to receive legal papers and government notices on the company’s behalf.3Justia. New Mexico Statutes Section 53-19-5 – Registered Office and Registered Agent The agent needs a physical street address in New Mexico (no P.O. Boxes) and has to be available during normal business hours. An individual agent must be at least 18, and a business entity acting as agent must be authorized to operate in the state.
You can be your own registered agent if you have a qualifying New Mexico address. Many owners hire a commercial registered agent service instead, which typically runs $50 to $300 per year, for privacy and consistent availability.
File the Articles of Organization
The Articles of Organization is the filing that legally creates your LLC. It goes through the Secretary of State’s online Business Portal. Paper filings are no longer accepted for any business application.4New Mexico Secretary of State. Online Services
The form asks for:
- Your LLC name with the required designator
- Your registered agent’s name, physical New Mexico street address, and signed consent
- The organizer completing the filing (does not need to be a member)
- Mailing and business addresses for the LLC
- Duration, which most LLCs list as perpetual
The filing fee is $50.2New Mexico Secretary of State. Online Filing System Processing usually takes one to three business days, and you’ll receive confirmation once the LLC legally exists.
Get a Federal EIN
An Employer Identification Number is a nine-digit federal tax ID from the IRS. Your LLC needs one if it has more than one member, hires employees, or files excise tax returns. A single-member LLC with no employees and no excise tax liability can technically use the owner’s Social Security number, but most owners still get an EIN because banks and vendors ask for it.5Internal Revenue Service. Single Member Limited Liability Companies
Apply at irs.gov. It’s free and the IRS issues the number immediately.6Internal Revenue Service. Get an Employer Identification Number Form the LLC with the state first, though. The IRS recommends waiting until state formation is complete, because applying earlier can delay the process.
Register With New Mexico Taxation and Revenue
Filing your Articles and getting an EIN does not finish your registrations. Any LLC doing business in New Mexico must also get a Business Tax Identification Number from the state’s Taxation and Revenue Department.7New Mexico Business Portal. Obtain Tax ID Numbers and Register a Business Before you apply, gather your federal EIN and your business registration number from the Secretary of State. Construction contractors also need their contractor license number. Registration happens online through the department’s website.
Gross Receipts Tax
New Mexico doesn’t have a traditional sales tax. It imposes a gross receipts tax on businesses for the privilege of doing business in the state. The state-level rate is 4.875%, and local governments add their own increments, so the combined rate depends on where you operate. Your BTIN registration determines your filing frequency. The Taxation and Revenue Department assigns a monthly, quarterly, or semi-annual schedule based on your expected taxable receipts.
Pass-Through Entity Income Tax
By default the IRS treats a multi-member LLC as a partnership and a single-member LLC as a disregarded entity, so profits and losses flow through to the owners’ personal returns. New Mexico follows that federal treatment but still requires the LLC to file a state income tax return as a pass-through entity.8NM Taxation & Revenue Department. Pass-Through Entity If any members are non-residents, the LLC must withhold state income tax from their share of net income. Because nobody withholds taxes from owner distributions, you’ll likely need to make quarterly estimated payments to both the IRS and the state.
Draft an Operating Agreement
An operating agreement is the internal rulebook for the LLC. It sets each member’s ownership percentage, how profits and losses are split, who makes management decisions, and what happens if a member wants out. You don’t file it with the state, but New Mexico law requires you to keep a copy at the LLC’s principal place of business.
Single-member LLCs should have one too. Without an agreement, a court can look at the LLC and see something that functions like a sole proprietorship, which weakens the liability protection you formed the LLC to get. The operating agreement is often the strongest piece of evidence that the LLC operates as a separate legal entity from you personally, and banks routinely ask for it when you open a business account. For multi-member LLCs the stakes climb higher, since disagreements over profit splits, voting rights, or exit terms become far harder to resolve when nothing is written down.
Industry Licenses and Local Permits
Formation and tax registration handle the general requirements. Your industry may add more. New Mexico’s Regulation and Licensing Department oversees professional licensing across dozens of fields, including real estate, pharmacy, cosmetology, private investigation and security, funeral services, chiropractic, and massage therapy.9NM Regulation and Licensing Department. Online Services Separate divisions in the same department cover alcoholic beverages, tobacco, cannabis, securities, mortgage lending, and construction trades.
Your city or county may also require a local business registration or permit. Requirements and fees vary by municipality, so contact the local city or county clerk’s office to confirm what applies. If your business touches any federally regulated activity, such as firearms, agriculture, or transportation, check with the relevant federal agency as well.
If You Hire Employees
Two additional registrations kick in the moment you start hiring.
Workers’ Compensation Insurance
New Mexico requires workers’ compensation coverage for any employer with three or more workers. If the LLC operates in construction or any trade licensed under the Construction Industries Licensing Act, you need coverage regardless of headcount.10FindLaw. New Mexico Statutes Chapter 52 Workers Compensation 52-1-6 – Application of Provisions of Act Farm and ranch laborers and private domestic servants are exempt.
Unemployment Insurance
Register with the New Mexico Department of Workforce Solutions to get an Employer Account Number. The department assigns your unemployment insurance tax rate based on industry and history. For 2026, the taxable wage base is $34,800 per employee.11New Mexico Department of Workforce Solutions. Unemployment Insurance Tax Information Activate the account promptly after registering so the department can accept your wage records and contribution payments.
Ongoing Compliance: No Annual Report
New Mexico LLCs are not required to file an annual report, and there is no annual fee to keep the LLC in good standing with the Secretary of State. In most states, missing an annual report can lead to administrative dissolution, so this is a genuine simplification.
No annual report does not mean no ongoing obligations. You still file gross receipts tax returns on your assigned schedule, submit the state pass-through entity income tax return each year, and keep your registered agent information current with the Secretary of State.
Protect the Liability Shield
The point of an LLC is the shield between your personal assets and business debts, but that shield isn’t automatic or permanent. New Mexico courts can disregard it through “piercing the veil” if they find the LLC wasn’t operated as a genuinely separate entity. Courts look at whether the LLC observed its own formalities, whether personal and business finances were kept separate, and whether the LLC was used for a legitimate business purpose.
Keep these records organized:
- Operating agreement and any amendments
- Financial records, including bank statements, profit and loss statements, and balance sheets
- Federal and state tax filings for each year
- Notes from any member votes or major decisions
- Contracts, leases, vendor agreements, and Secretary of State filings
Keep business funds in a dedicated bank account. The fastest way to lose liability protection is to treat the LLC’s money as your own. Courts view commingling as strong evidence that the LLC is just an alter ego of its owner.
If Your LLC Was Formed in Another State
If you already have an LLC in another state and want to do business in New Mexico, you don’t form a new one. File a Foreign LLC Application for Registration with the Secretary of State. The filing fee is $100, and you’ll need a Certificate of Good Standing from your home state dated within 30 days of submission. You also appoint a registered agent with a physical New Mexico address, the same as a domestic LLC. The application asks for the LLC name as registered in your home state, the date and state of formation, the principal office address, and the names and addresses of the managers.
Beneficial Ownership Reporting
As of March 2025, FinCEN issued an interim final rule that exempts all domestically formed companies from Beneficial Ownership Information reporting under the Corporate Transparency Act.12FinCEN. FinCEN Removes Beneficial Ownership Reporting Requirements for U.S. Companies and U.S. Persons A New Mexico LLC formed within the state currently has no obligation to file a BOI report. FinCEN has said it intends to finalize a revised rule, so the situation is worth monitoring, but no action is required now.
