New Mexico is one of the only states in the country that never requires an LLC to file an annual or biennial report with the Secretary of State. Once your Articles of Organization are approved, the only ongoing state-level obligation is keeping a registered agent in place.

That single fact makes New Mexico one of the lowest-maintenance LLC states available, and it's the reason so many founders ask about it. The formation steps themselves follow a familiar pattern: name, registered agent, formation filing, EIN, then the federal filings that apply to foreign-owned entities.

TL;DR

  • No annual report, ever: New Mexico is one of the rare states with zero recurring Secretary of State filing or fee for LLCs after formation.
  • Step 1, name: confirm your LLC name is distinguishable and includes "LLC" or "Limited Liability Company," and reserve it for $20 if you're not ready to file.
  • Step 2, registered agent: you need a physical New Mexico street address (no PO box) to receive legal notices continuously.
  • Step 3, Articles of Organization: file online with the Secretary of State for $52 total, with approval typically in 1 to 3 business days.
  • Step 4, EIN: free from the IRS, online for SSN or ITIN holders, by phone, fax, or mail via Form SS-4 for founders without one.
  • Step 5, Form 5472: a 25%+ foreign-owned single-member LLC must file this annually, even at zero revenue, or risk a $25,000 minimum penalty.
  • Ongoing compliance: no annual report, but Gross Receipts Tax and state income tax can still apply if you have real New Mexico nexus.

Why Form an LLC in New Mexico

Most states require an LLC to file a report, and pay a fee, on some recurring schedule just to stay in good standing. New Mexico doesn't. Once your Articles of Organization are approved, there is no annual report and no biennial report owed to the Secretary of State at all.

The only thing New Mexico asks an LLC to keep current after formation is its registered agent. That makes it one of the most privacy-friendly, lowest-maintenance states to maintain an LLC in, since there's no recurring filing that republishes your business details every year.

New Mexico also has a reputation for allowing more owner privacy than most states, since member and manager names generally aren't required on the Articles of Organization. We'd treat that as a helpful pattern rather than a guarantee, and confirm current requirements directly with the Secretary of State before relying on it.

None of this means New Mexico is tax-free. If your LLC actually operates in the state, sells to New Mexico customers, or has New Mexico-source income, you can still owe New Mexico income tax and Gross Receipts Tax, covered in Step 6 below.

Step 1: Choose and Reserve Your LLC Name

Your name has to be distinguishable from every other business already registered in New Mexico, and it must include a designator showing it's an LLC.

  • Required designator: the name must contain "Limited Liability Company," "LLC," or "L.L.C."
  • Distinguishability: it can't be identical or confusingly similar to an existing registered business name in the state.
  • Reservation: the "Application for Reservation of a Domestic LLC Name" holds a name for 120 days for a $20 fee, and is renewable for another 120 days for another $20.

The reservation form has historically been filed by mail, though we'd confirm the current filing method directly on the New Mexico Secretary of State's site before relying on it, since online options change without much notice.

Reserving a name isn't required if you're ready to file your Articles of Organization right away. It's only useful if you want to lock in a name before you're ready to complete the rest of formation.

Step 2: Appoint a Registered Agent

Every New Mexico LLC needs a registered agent: a person or company with a physical street address in the state, available to receive legal notices and state correspondence on the LLC's behalf. This requirement is grounded in New Mexico's LLC statute, commonly cited as NMSA 1978 Section 53-19-5, though we'd verify the exact citation against the current statute text before publishing it as authoritative.

  • Physical New Mexico address required: a PO box doesn't qualify.
  • Continuous maintenance: the agent has to be in place for as long as the LLC exists, not just at formation.
  • Commercial service is common: founders without a New Mexico address typically use a paid registered agent service to satisfy this requirement.

Since New Mexico has no annual report, the registered agent is effectively the one compliance item the state actively checks on an ongoing basis. Letting it lapse is the fastest way to fall out of good standing in an otherwise low-maintenance state.

Step 3: File Your Articles of Organization

The Articles of Organization is the filing that legally creates your LLC. New Mexico now requires this to be filed online with the Secretary of State, a shift from earlier paper-based filing that we'd confirm is still current before relying on it for a specific filing date.

Base filing fee$50
Online transaction fee$2
Total cost$52
Processing time1 to 3 business days
Publication requirementNone

New Mexico has no confirmed expedited filing option, so budget for the standard 1 to 3 business day window rather than assuming a rush path exists. There's also no publication requirement, which some states impose as an extra post-filing step and cost.

Step 4: Get an EIN, Even Without an SSN

An Employer Identification Number (EIN) is what the IRS uses to identify your LLC for tax purposes, and it's free directly from the IRS either way you apply.

  • SSN or ITIN holders: apply online and typically receive the EIN the same session.
  • Founders without an SSN or ITIN: apply using Form SS-4 by phone, fax, or mail, since the online tool isn't available without one.

The manual route takes longer and depends on how completely the form is filled out the first time. A rejected or incomplete SS-4 means resubmitting and waiting again, so getting the responsible-party details right the first time matters more here than in the online flow.

Step 5: File Form 5472 if the LLC Is Foreign-Owned

If your single-member LLC is 25% or more foreign-owned, the IRS requires an annual Form 5472 filing, even if the LLC had zero revenue for the year.

  • Filed with a pro forma Form 1120, a placeholder corporate return required alongside the 5472, even though the LLC itself owes no separate corporate income tax.
  • Reports transactions between the LLC and its foreign owner, such as capital contributions or payments for services.
  • Minimum penalty of $25,000 per form, per year, for a late or missing filing, regardless of whether the LLC made money.

This requirement exists independently of anything New Mexico requires at the state level. A dormant LLC with no state-level filing obligation can still owe this federal one, and the IRS doesn't waive it for founders who didn't know it applied.

Step 6: Handle Ongoing Compliance

New Mexico's standout feature is that there's no annual report and no biennial report owed to the Secretary of State, ever. Your only recurring state-level obligation is keeping the registered agent current.

That doesn't mean New Mexico is tax-free for every LLC. Two separate taxes can apply if you have real activity in the state:

  • State income tax: New Mexico taxes pass-through LLC income for residents and New Mexico-source income across six graduated brackets, from 1.5% on income up to $5,500 to 5.9% on income over $210,000 for single filers.
  • Gross Receipts Tax (GRT): New Mexico has no traditional sales tax. Instead it imposes GRT on the business making the sale, which is often passed to the customer. The state rate is roughly 4.88%, and combined state-plus-local rates typically range from about 5.25% to 9.44%, averaging around 7.67%.

A founder with no New Mexico operations, employees, or customers generally won't owe New Mexico income tax or GRT. GRT becomes a real ongoing cost once you have actual nexus in the state, meaning customers, staff, or a physical presence there.

If your LLC ever needs to operate in a state other than New Mexico, that's a separate foreign qualification filing with that other state, not something New Mexico's own compliance calendar covers. Check the New Mexico Secretary of State's site directly for current foreign-entity fees if the reverse applies to you.

Common Mistakes to Avoid

  • Assuming "no annual report" means no taxes: the Secretary of State filing and your tax obligations are separate. GRT and state income tax can still apply with real New Mexico nexus.
  • Letting the registered agent lapse: it's the one thing New Mexico actively requires you to maintain, and it's easy to overlook precisely because there's no annual filing to remind you.
  • Treating the EIN as the finish line: for a foreign-owned LLC, the EIN is closer to the starting gun on an annual Form 5472 obligation than the end of the process.
  • Skipping Form 5472 because there's no revenue: the filing requirement doesn't depend on whether the LLC made money.
  • Assuming a mailed name reservation form is still current: filing methods change, so confirm directly with the Secretary of State before assuming mail is still required.

FAQ

Does a New Mexico LLC really have no annual report requirement?

Correct. New Mexico is one of the few states that imposes no annual report and no biennial report on LLCs with the Secretary of State. Your only ongoing state-level obligation is maintaining a registered agent with a valid New Mexico address. This doesn't remove separate tax obligations like Gross Receipts Tax or state income tax if you have real activity in New Mexico.

How much does it cost to form an LLC in New Mexico?

The Articles of Organization filing costs $52 total, made up of a $50 base fee plus a $2 online transaction fee. A registered agent service typically adds an annual cost on top of that if you're not using your own New Mexico address. Reserving a name before filing costs an additional $20 for a 120-day hold, renewable once for another $20.

Do I owe New Mexico taxes if I don't live or operate there?

Generally no. A non-resident founder with no New Mexico operations, employees, or customers typically won't owe New Mexico state income tax or Gross Receipts Tax. Both taxes are tied to having real nexus in the state, meaning actual business activity there, not just forming the LLC under New Mexico law. Confirm your specific situation with a tax professional before assuming either way.
