Form a New Mexico LLC from Argentina: Complete 2026 Guide

Forming an LLC in New Mexico costs $50 in state filing fees ($50 online where available), plus a registered agent, required in every state and typically $100-150/year. Ongoing state costs are $0 ever — New Mexico is one of the only states with no ongoing annual report or annual fee for LLCs. Beyond the state fee, budget for a free IRS EIN application, a US business bank account (typically free with Mercury or Relay), and optionally a formation-service bundle. EasyBrise's Global Launch plan runs $295 for year one, including a registered agent, and $149/year to renew — most founders budget well under $500 for the full first year, state fee included.

New Mexico is one of the most popular states for non-US founders forming a US LLC. Filing costs $50 by mail or $50 online, and the ongoing burden is light: $0 ever — New Mexico is one of the only states with no ongoing annual report or annual fee for LLCs. New Mexico does not tax LLC income earned outside the state for non-resident owners, which simplifies your state-level compliance even though home-country tax obligations remain separate. New Mexico does not publicly disclose member or manager names in its formation records. For a founder outside the US who wants a low-maintenance LLC, New Mexico consistently ranks among the top choices for non-US founders.

New Mexico tends to be the right fit if minimizing ongoing paperwork is the top priority — no annual report, ever, is unique among these five states — and strict privacy matters more to you than name recognition. Compare it against the other four states on cost, privacy, and reporting before filing — switching states later means dissolving and re-forming, not a simple amendment.

Most Argentina-based founders bank with Mercury or Relay, both listing foreign-owned LLCs as eligible applicants, though approval depends on each bank's own review. You'll typically need your EIN letter (CP 575, or Form 147C if lost), Articles of Organization, and ID. From there, Stripe and PayPal both list foreign-owned US LLCs as eligible for an account, subject to underwriting — letting you invoice and collect USD from clients worldwide without a local Argentina merchant account.

Argentine founders often form a US LLC to reach USD-paying international clients and avoid some of the friction of Argentina's own currency controls (cepo cambiario) when billing or holding funds outside the peso system. There is no US-Argentina income tax treaty, which is somewhat unusual among major economies, so any double-taxation relief on income taxed in both countries relies on Argentina's own unilateral foreign tax credit mechanism rather than a treaty framework.

Once your New Mexico LLC and EIN are in place: sign an Operating Agreement (the document banks and processors most often ask for, even where not legally required), and don't worry about federal Beneficial Ownership Information reporting — FinCEN's August 2026 rule permanently exempts US-formed LLCs from federal BOI reporting. Then open your bank account, apply for Stripe and/or PayPal (subject to each provider's own eligibility review), and calendar your annual state filing plus your federal Form 5472/1120 deadline.

Argentina taxes residents on worldwide income, and profits from a foreign entity like a US LLC are generally reportable to AFIP (now ARCA), with the absence of a US-Argentina tax treaty making it especially important to confirm with an Argentine accountant how foreign tax credits and reporting apply to your specific structure, particularly given Argentina's currency-control history. On the US side, the LLC's obligations are unaffected by where the owner lives: a foreign-owned single-member LLC files Form 5472 alongside a pro forma Form 1120 every year, with a $25,000 minimum penalty for a missed or incomplete filing.

The process is the same for any Argentina-based founder regardless of state: choose a name, file Articles of Organization with the New Mexico Secretary of State (directly or via your registered agent), appoint a registered agent with a physical New Mexico address, then apply for an EIN. Without a US SSN, you leave that field on Form SS-4 as "Foreign"/"N/A" and apply by phone (same-week, roughly 45-60 minutes on the international line) or fax/mail (4-6 weeks). Once you have the EIN, open a US business bank account remotely with Mercury or Relay and start invoicing.
