Overview
New Mexico business registration runs through the Secretary of State (SOS), specifically its Business Services Division, which keeps the official record of entities formed or registered to do business in the state. Filings and searches go through the SOS Enterprise portal at enterprise.sos.nm.gov.
New Mexico matters for KYB work mainly because of how little it discloses about LLCs. When an LLC files its Articles of Organization, it does not have to name its members or managers, so LLC ownership and control stay off the public register entirely. Combined with a single $50 formation fee and, historically, no recurring report, this has made New Mexico one of the most popular states for anonymous LLCs. Anyone diligencing a New Mexico LLC should expect the register to confirm only the entity's existence, status, and registered agent, and should plan to source ownership from elsewhere.
The recurring filing rules differ by entity type. Corporations file a biennial report every two years. Nonprofits file annually. LLCs historically filed nothing, but the Revised Uniform Limited Liability Company Act (HB 281, effective July 1, 2024) introduces a triennial report, filed every three years; its implementation is still rolling out as the SOS updates its rules and portal. The triennial report updates registered agent and address information rather than reaching into ownership.
New Mexico has no state-level beneficial ownership register. At the federal level, the Corporate Transparency Act (2021) created a BOI registry run by FinCEN, but a March 2025 interim final rule lifted the obligation for all U.S. companies and U.S. persons. Only foreign reporting companies remain subject to it. For New Mexico LLCs, this combination means ownership is often not available from any public source.
For KYB and AML work, the free SOS search returns an entity's status, business ID, registered agent, principal office, and, for corporations, the officers and directors named in the biennial report. LLC member and manager data is not part of the public record.
Official Registers
Secretary of State (Business Search)
The SOS Business Services Division maintains the official register through its business search on the Enterprise portal. It records domestic and foreign corporations, LLCs, nonprofit corporations, limited partnerships, and limited liability partnerships.
Search and access. The business search is free and needs no account. Search by entity name or business ID. Each record shows the entity name, business ID, type, status, registration date, registered agent name and address, and principal office. For corporations, the officers and directors from the biennial report are also visible. For LLCs, no member or manager is shown.
Business ID. New Mexico assigns each entity a business ID at registration, which is the primary identifier across the register and the key most lookups run on.
Filings. Formation documents go in online through the SOS Enterprise portal. Articles of Organization for a domestic LLC cost $50, a one-time fee with no recurring annual report historically attached. Articles of Incorporation for a domestic corporation start at $100, based on the number of authorised shares. Nonprofit Articles of Incorporation cost $25.
Certificates. Certificates of Good Standing and certified copies of filed documents are available from the SOS for a fee.
Registration and Publication Requirements
Corporations
All domestic and foreign for-profit corporations must register with the SOS and maintain a registered agent at a New Mexico address.
Biennial report. Corporations file a biennial report every two years, due by the fifteenth day of the third month after the close of the corporation's tax year, at a $25 fee. The report carries the principal office, the registered agent, and the names of the officers and directors, all of which become part of the public record.
Failing to file leads the SOS to administratively dissolve a domestic corporation or revoke a foreign corporation's authority to do business. The entity must then be reinstated to return to good standing.
Financial statements. There is no public financial disclosure requirement.
LLCs
All domestic and foreign LLCs must register with the SOS and maintain a registered agent in New Mexico. Domestic formation costs $50.
Member and manager privacy. The Articles of Organization do not require naming members or managers, and that information is not collected by the SOS. New Mexico LLC ownership and control are therefore not on the public record at all, which is the defining feature of the New Mexico LLC for due-diligence purposes.
Triennial report. Historically, New Mexico LLCs filed no recurring report. Under the Revised Uniform Limited Liability Company Act (HB 281, effective July 1, 2024), LLCs are subject to a triennial report filed every three years, at a $20 fee, with implementation still rolling out. The first report is due by the end of the third calendar month after the LLC's formation or registration, then in that same month every three years. The report updates the registered agent and address rather than disclosing ownership.
Nonprofit corporations
Nonprofits register with the SOS and file an annual report, due by the fifteenth day of the fifth month after the close of their fiscal year, at a $10 fee. Directors and officers appear on the public record. Federal 501(c) status comes from the IRS; the state filing does not grant it.
Limited partnerships and LLPs
Limited partnerships register with the SOS and maintain a registered agent in New Mexico. Limited liability partnerships register as well and, unlike LLCs, file an annual report each year, due between January 1 and April 1. Both must maintain a registered agent in the state.
Sole proprietors and general partnerships
Sole proprietors and general partnerships do not register as entities with the SOS and do not appear as registered entities in the business search.

Financial statements aren't filed publicly in New Mexico. New Mexico LLCs do not disclose members or managers to the SOS, so LLC ownership cannot be sourced from the register and must be established through other means. Domestic companies are also exempt from federal BOI reporting following the March 2025 FinCEN rule.
