Quick Answer: Forming an LLC in New Mexico
The New Mexico Secretary of State (SOS) is the primary point of contact for LLC formation. The process involves:
- Search for and reserve a compliant business name through the NM SOS database.
- Designate a qualified New Mexico registered agent.
- File Articles of Organization with the NM SOS (online or by mail).
- Draft an operating agreement for internal governance.
- Obtain an Employer Identification Number (EIN) from the IRS.
- Register with the New Mexico Taxation and Revenue Department (NM TRD) for Gross Receipts Tax if selling goods or services in the state.
New Mexico's LLC framework is governed by the New Mexico Limited Liability Company Act (NMSA 1978, Chapter 53, Article 19). This act defines naming rules, member rights, and other operational aspects.
Step-by-Step Guide to Forming Your New Mexico LLC
1. Search for a Name
Confirm your preferred name is available before filing. The NM SOS maintains a searchable business entity database at portal.sos.state.nm.us. If the name is taken or too similar to an existing entity, your Articles will be rejected.
