New Mexico LLC Operating Agreement: Is One Required and What to Include

New Mexico LLC Operating Agreement: Is One Required and What to Include

Short answer: New Mexico does not require an operating agreement to form an LLC. You should still write one. The state never sees it, but your bank, your lenders, and any co-owner who later disagrees will want a clear record of how the company is supposed to run. This guide covers what New Mexico requires, what it does not, and what a New Mexico operating agreement should include.

This guide is informational only. It is not legal or tax advice. Before you sign an operating agreement or make tax decisions based on it, talk with a New Mexico attorney and a certified public accountant (CPA), especially if you have more than one owner, outside investors, or a complicated tax situation.

Is a New Mexico LLC operating agreement required?

No. The only document you must file with the state to form a New Mexico LLC is the Articles of Organization. The filing fee is $50, and you submit it online through the Secretary of State's SOS Enterprise Business Filing System at enterprise.sos.nm.gov. Your operating agreement is not one of the documents you submit. It is a private contract among the members, and the Secretary of State never files or reviews it. Forming the LLC does not depend on having one.

That does not mean you can skip it. Put the agreement in writing, since a written document is the expected practice. Banks and lenders also expect one. Many will ask for a copy before they open a business account or approve a loan, so confirm what your bank requires before you assume a verbal arrangement will be enough.

What happens if you don't have one

If you have no written operating agreement, the default rules in the LLC Act govern how your company runs. The most important default is management structure. An LLC is member-managed by default, which means the members run the business together unless the Articles of Organization say otherwise. The defaults answer questions you may never have discussed, such as how major decisions are made and what happens to a departing owner's interest. Those defaults are what a court or a state official would apply if co-owners disagreed, and they rarely match what the owners actually intended.

Whether and how those default rules apply to your specific situation is a question for a New Mexico attorney.

Decide the management structure before you file

Management structure is chosen in the Articles of Organization, not in the operating agreement, so settle it before you file. In a member-managed LLC, the members run the business. In a manager-managed LLC, you name one or more managers to run it, and members who are not managers typically have less direct control. Choose the structure that matches who will actually make decisions day to day.

If you later want to switch structures, the change goes through the Secretary of State. Confirm the process and cost on the SOS website before you assume it will be simple.

What a New Mexico operating agreement should cover

A complete agreement addresses at least the topics below. Each one is a common point of conflict between owners when it was never written down.

  • Ownership percentages: each member's share of the LLC and how that share was determined.
  • Capital contributions: what each member contributed (cash, equipment, property, or services), what value was assigned to it, and what happens if the business needs more money later.
  • Profit and loss splits: how income and losses are allocated, whether that matches ownership percentages, and when distributions are paid.
  • Voting: which decisions need a simple majority, a supermajority, or unanimous consent, such as selling the business, taking on significant debt, or admitting a new member.
  • Manager or member authority: who may sign contracts, open bank accounts, hire staff, and spend company money, and any dollar limits on that authority.
  • Transfers and buyouts: whether a member can sell or transfer an interest, whether the other members get the first right to buy it, and how the price is set.
  • Death, disability, or exit: what happens to a member's interest after death, disability, divorce, bankruptcy, or a voluntary departure, and whether the company can or must buy the interest out.
  • Dissolution: the events that would end the LLC, who has the authority to decide, and how remaining assets are divided after debts are paid.

Single-member LLCs still need one

A single-owner LLC has no one to split profits with or to vote against, so it may seem unnecessary. It is still worth writing one. A written agreement gives your bank and any future buyer a clear record of who controls the company and who can sign for it. It also addresses what happens to the business if you die, become disabled, or can no longer run it. Those are the situations that most often leave a one-owner business stuck, and they are easy to plan for in advance. Talk with a New Mexico attorney about the terms that fit a one-owner company.

New Mexico filing and tax points that affect the agreement

None of the points below require an operating agreement, but several affect how you write one and what you keep on file.

  • No annual or biennial report: a New Mexico LLC files no annual or biennial report with the Secretary of State and pays no fee for one. Corporations are different, since they file a biennial report and pay a $25 fee for it.
  • No LLC franchise tax: an LLC that is taxed as a default pass-through entity does not owe the $50 annual corporate franchise tax. An LLC that elects to be taxed as a corporation files form CIT-1 and owes that $50 annual franchise tax.
  • Tax registration: an LLC that does business in New Mexico registers with the Taxation and Revenue Department (TRD) for a Business Tax Identification Number (BTIN, formerly called a CRS number) at no charge. The BTIN is a tax registration, not a license, and it is how the LLC reports gross receipts tax.
  • Gross receipts tax: New Mexico has no sales tax. Instead, the gross receipts tax is imposed on the seller. The state rate is 4.875%, and combined state and local rates run from 5.25% to 9.4375% under the schedule effective July 1, 2026 through June 30, 2027. The rate depends on where the sale takes place, so confirm the rate for your location with TRD.
  • Local registration: New Mexico has no general statewide business license. Cities and some counties charge their own flat annual business registration. The amount varies by jurisdiction, so check with your city or county clerk before you open.
  • Trade names: New Mexico has no statewide DBA or assumed-name registration. If the LLC will trade under a different name, state that name in the Articles of Organization.

Confirm how the profit and loss splits in your agreement will be reported for federal and state tax purposes. The allocations you write should match what your CPA files. Do not assume that a template's tax language fits your situation.

Step-by-step: putting it together

  1. Decide the management structure (member-managed or manager-managed) before you file.
  2. File the Articles of Organization online through SOS Enterprise for $50.
  3. Draft the operating agreement using the topics listed above, or have an attorney draft it.
  4. Sign it and keep it with your company records. Give a copy to your bank and any lender that asks for one.
  5. Register for a BTIN with TRD if the LLC will do business in New Mexico, and confirm whether your city or county requires its own registration.

Using a template for a New Mexico LLC operating agreement

Searches for a new Mexico LLC operating agreement template return many free and paid forms, and a template is a reasonable starting point because it lists the topics you need to cover. Be cautious, though. Because the Secretary of State does not file or review the agreement, nothing checks its quality except you and the people who sign it. A template written for another state may rely on different default rules, may use tax language that does not fit a New Mexico LLC, or may omit the buyout and exit terms that matter most to co-owners.

If you use a template, read every clause, fill in the blanks with terms you have actually agreed on, and have a New Mexico attorney review the final version. The same advice applies to any NM LLC operating agreement, whether it started from a template or from scratch.

Bottom line

New Mexico does not require an operating agreement to form an LLC. The only state filing to form the company is the $50 Articles of Organization, and the Secretary of State never receives the agreement. Write one anyway. Decide the management structure before you file, cover ownership, money, voting, authority, transfers, exit, and dissolution, and keep a signed copy with your records. Because the LLC files no annual report, the agreement is the document that will guide your business for years, so have a New Mexico attorney and a CPA review it before you rely on it.
