How to Start an LLC in New Mexico (Quick Answer)
To start an LLC in New Mexico, file the Articles of Organization online with the New Mexico Secretary of State, and pay the $52 total filing fee. Once the state approves it, your LLC legally exists, and New Mexico then requires no annual or biennial report, so keeping a registered agent in place is the only ongoing state obligation.
| Filing document | Articles of Organization |
| Filing fee | $52 total, one time ($50 base fee plus a $2 online transaction fee) |
| Where to file | New Mexico Secretary of State, filed online |
| Processing time | 1 to 3 business days; no confirmed expedited option |
| Registered agent | Required, a registered agent with a physical New Mexico street address, not a PO box, maintained continuously (a paid service if you're not in New Mexico) |
| EIN without an SSN? | Yes, file Form SS-4 by phone, fax, or mail (no ITIN required) |
| Form 5472 (foreign-owned)? | Required yearly for 25%+ foreign-owned single-member LLCs, $25,000 minimum penalty if missed |
| Annual filing | None, ever. New Mexico requires no annual or biennial report with the Secretary of State; the only ongoing state obligation is keeping a registered agent in place. |
| State income tax | New Mexico taxes pass-through LLC income for residents and on 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. It also imposes a Gross Receipts Tax, state rate roughly 4.88%, but both only apply once you have real New Mexico nexus. |
First-year cost: $52 if you file the Articles of Organization yourself. If you are not based in New Mexico, add a registered-agent service, commonly $35 to $300 a year, plus an optional $20 name reservation.
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.
| Item | Detail |
|---|---|
| Base filing fee | $50 |
| Online transaction fee | $2 |
| Total cost | $52 |
| Processing time | 1 to 3 business days |
| Publication requirement | None |
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.
Draft an Operating Agreement
New Mexico's Articles of Organization generally don't carry member or manager names, which is a large part of the state's privacy appeal. It also means nothing on the public record says who owns the LLC or how it's run. The operating agreement is where you settle that.
- Fix the ownership split. Record each member's percentage, what they contributed, and how a new member gets admitted, so ownership isn't reconstructed from memory or from an old chat thread later.
- Set profit distribution and management. Spell out how distributions are calculated and when they're paid, and whether the LLC is member-managed or run by a manager with defined authority.
- Decide what happens when a member exits. Buyout terms, how an interest gets valued, and the voting threshold for approving a transfer are the clauses founders wish they'd written once someone actually wants out.
Keep the signed copy with the LLC's internal records, alongside your approved Articles of Organization and EIN letter. Even a single-member LLC benefits, since banks routinely ask to see one.
Open a US Business Bank Account
Once your Articles of Organization are approved and the EIN has arrived, open a dedicated business bank account before the LLC moves a single dollar.
- Bring the paperwork. Banks typically ask for the approved Articles of Organization, your EIN confirmation letter, an operating agreement even though it's an internal document, and a government-issued ID for whoever signs on the account.
- Keep funds separate from day one. Running personal and business money through the same account is one of the fastest ways to undermine the liability protection an LLC is supposed to provide.
- Non-US founders should expect extra verification. Some banks want an in-person visit or additional identity documents before opening an account without a US-based owner present, so confirm a specific bank's requirements before counting on a fully remote setup.
No New Mexico filing is involved in this step; it's entirely a bank-side process. It's also the step most likely to stall a remote formation, so start it as soon as the EIN letter lands.
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.
New Mexico LLC Costs Breakdown
New Mexico is one of the cheapest states to keep an LLC alive, largely because there's no recurring Secretary of State report to pay for. Here is every figure this guide cites.
| What you pay | Amount | When |
|---|---|---|
| Name reservation (optional) | $20, renewable once for another $20 | Before filing; holds the name 120 days, renewable for another 120 |
| Articles of Organization, base filing fee | $50 | At formation |
| Online transaction fee | $2 | At formation |
| Articles of Organization, total | $52 | At formation |
| Expedited filing | No confirmed option | Not available |
| Newspaper publication | None required | Not applicable |
| EIN from the IRS | Free | After formation |
| Annual or biennial report | None, ever | No recurring Secretary of State filing or fee |
Registered agent service is the one recurring cost this guide doesn't put a figure on, and it's the single item New Mexico does require you to keep current. Gross Receipts Tax and state income tax sit outside this table and only apply if you have real New Mexico nexus.
How Long Does It Take to Form an LLC in New Mexico?
New Mexico approves Articles of Organization filed online with the Secretary of State in 1 to 3 business days, which is fast by any standard. There's no confirmed expedited option, so budget for that standard window rather than assuming a rush path exists when a deadline is tight.
Reserving the name first doesn't speed anything up. It holds a name for 120 days for $20, renewable once for another $20, which only helps if you want to lock in a name before you're ready to complete the rest of formation.
The federal steps set the real pace. An SSN or ITIN holder can get an EIN online in the same session, while founders without one apply with Form SS-4 by phone, fax, or mail, and an incomplete form means resubmitting and waiting again.
The bank account comes last, since banks want the approved Articles of Organization and the EIN letter in hand. For a non-resident founder that's usually the slowest part of the sequence.
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.
Do I need an operating agreement for a New Mexico LLC?
It isn't part of the formation filing, but you want one anyway. New Mexico's Articles of Organization generally don't carry member or manager names, so nothing on the public record documents who owns the LLC or how profits get split. The operating agreement is the only place that lives.
It matters practically too. Banks commonly ask to see one when you open a business account, and an agreement that already settles ownership percentages, management, and what happens when a member leaves is far easier to write before a disagreement than after one.
Can a non-US resident start an LLC in New Mexico?
Yes. New Mexico sets no residency or citizenship requirement to own an LLC. You'll still need a registered agent with a physical New Mexico street address, which usually means a paid service if you're not in the state. Because you won't have an SSN, you apply for your EIN on Form SS-4 by phone, fax, or mail instead of the online tool. If your LLC is single-member and 25% or more foreign-owned, you also file Form 5472 with the IRS every year, even at zero revenue, or risk a $25,000 minimum penalty.
What are the annual filing requirements for a single-member LLC in New Mexico?
New Mexico is one of the rare states that imposes no annual report and no biennial report on LLCs with the Secretary of State, including single-member ones. The only ongoing state obligation is keeping a registered agent with a valid New Mexico address in place. Separate tax obligations, like Gross Receipts Tax or state income tax, can still apply if you have real activity in the state. A single-member LLC that is 25% or more foreign-owned also has a federal obligation: Form 5472, filed yearly with the IRS, even at zero revenue, or risk a $25,000 minimum penalty.
Does a New Mexico LLC pay income tax?
New Mexico does tax LLC income. It taxes pass-through LLC income for residents and on 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. It also imposes a Gross Receipts Tax, roughly 4.88% at the state level, on the business making the sale, though this only becomes a real cost once you have actual New Mexico nexus. A founder with no New Mexico operations, employees, or customers generally won't owe either. Federally, a standard LLC is a pass-through entity, so profits are reported on the owners' personal returns.
