State tax guides

New Mexico LLC & corporation registration and tax requirements

A general guide to forming, registering and keeping a company compliant in New Mexico. Businesses are registered with the Secretary of State. New Mexico's gross receipts tax applies to many services as well as goods, so most active businesses need to register with the Taxation and Revenue Department.

Single-member LLCs in New Mexico

A single-member LLC is registered with the Secretary of State by filing articles of organization. For federal tax purposes it is usually a disregarded entity, and its ongoing New Mexico obligations typically include: annual or biennial report for corporations; LLCs generally have no annual report. New Mexico taxes individual income, so owners of pass-through LLCs and S corporations generally report their share of New Mexico-source profit on a New Mexico return—as residents or as nonresidents.

Multi-member LLCs in New Mexico

A multi-member LLC is generally taxed as a partnership and files a federal Form 1065 with K-1s for each member. In New Mexico, it keeps the same registration and report obligations, and the state may require a partnership return or withholding for nonresident members. Business-level taxes to watch: Gross receipts tax on most sales and services, plus corporate income tax.

Corporations in New Mexico

A corporation files articles of incorporation with the Secretary of State, appoints directors and officers, and keeps its New Mexico registration current. Gross receipts tax on most sales and services, plus corporate income tax. Corporations also file federal Form 1120 and, when doing business in New Mexico, a New Mexico corporate return where one is required.

S corporations in New Mexico

An S corporation is a federal tax election (Form 2553), not a separate entity type. Not every state treats S corporations the same way—in New Mexico, review how the state taxes S corporation income and whether entity-level taxes or fees still apply. Nonresident aliens cannot be S corporation shareholders, so foreign owners usually use an LLC or C corporation instead.

Foreign-owned U.S. LLCs and corporations in New Mexico

Foreign individuals and companies can own an LLC or corporation in New Mexico. State requirements are generally the same as for U.S. owners, but federal rules add filings such as Form 5472 with a pro forma Form 1120 for foreign-owned single-member LLCs, and possible withholding on income allocated to foreign partners. Chirino USA helps foreign owners keep both the New Mexico filings and the IRS filings in order.

Companies formed in another state that do business in New Mexico

An LLC or corporation formed elsewhere—such as in Delaware, Wyoming or Florida—that has employees, an office, property or regular operations in New Mexico usually must register as a "foreign" entity with the Secretary of State (foreign qualification). Once registered, it generally follows New Mexico's report and tax rules as well as those of its home state.

Registered agent requirements

Every LLC and corporation registered in New Mexico must keep a registered agent with a physical address in the state to receive legal and state notices. Owners who live abroad or in another state typically use a commercial registered agent service.

General filing deadlines

Annual or periodic report: Annual or biennial report for corporations; LLCs generally have no annual report. State income or franchise tax returns generally follow federal due dates or shortly after, and extensions for state returns do not always extend the time to pay. Missing state filings can lead to penalties, loss of good standing and eventual administrative dissolution.

Multi-state business considerations

Companies that sell, hire or hold property in more than one state may have to register and file in each of them. Income is usually apportioned among states, and sales tax registration can be triggered separately from income tax. We review where your company is "doing business" so you file in New Mexico and other states only where required.

This guide is general information and not legal or tax advice. State rules, fees and deadlines change; we confirm current requirements for your situation before filing.
