    Why New Mexico

    What makes New Mexico worth a look for someone in Portugal: the state fee is $50 on paper ($50 online), and after that the state-level upkeep is $0 ever — New Mexico is one of the only states with no ongoing annual report or annual fee for LLCs. The state levies no tax on LLC income earned outside the state for non-resident owners. New Mexico does not publicly disclose member or manager names in its formation records. None of this changes your Portugal tax position, which sits on top of the US picture, but it does mean New Mexico itself adds little friction. Among the five states we cover, New Mexico is the only one of the five with no annual filing at all.

    For Portuguese Founders

    Portuguese freelancers, developers, consultants and online sellers form US LLCs to invoice international clients in dollars, hold a US business bank account and present a domestic US vendor to American customers. Portugal is in the euro area, so a Portuguese owner funds the LLC with an ordinary international transfer in euros converted to dollars. A Portuguese tax resident is taxed on worldwide income, so the main questions concern how Portugal treats the income and whether any special regime applies to you.

    After Formation Checklist

    Checklist once the EIN letter arrives: (1) Operating Agreement signed and stored; (2) bank account application submitted; (3) Stripe and/or PayPal applications, subject to their own review; (4) there is no New Mexico annual filing to calendar in your calendar; (5) Form 5472 with a pro forma 1120 on the federal calendar. Federal Beneficial Ownership Information reporting is not something you need to do: FinCEN's rule in force since August 14, 2026 permanently exempts all US-formed LLCs.

    Is New Mexico Right For You

    Choose New Mexico when 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. If your priorities lean another way, compare the other four states first, because moving a New Mexico LLC to another state later means dissolving it and forming a new one.

    Calling The IRS From Portugal

    The IRS international EIN line (267-941-1099) answers from 6 a.m. to 11 p.m. Eastern. Portugal is five hours ahead of Eastern Time for most of the year, so the window runs from 11 a.m. to 4 a.m. Portuguese time, with a shorter gap for a few weeks when the US and Europe change clocks on different dates. Any daytime or evening call is comfortable. Plan on 45-60 minutes.

    Forming In New Mexico Step By Step

    Forming from Portugal is a five-step job. One: choose and check the name. Two: appoint a registered agent with a physical New Mexico address. Three: file the New Mexico formation documents. Four: obtain the EIN, entering "Foreign" or "N/A" where Form SS-4 asks for an SSN or ITIN; by phone on 267-941-1099 it takes about 45-60 minutes, by fax or mail 4-6 weeks. Five: open the business bank account online. No US trip is needed at any point.

    New Mexico LLC For Portuguese Founders

    New Mexico suits a Portuguese founder who wants the lightest US paperwork: a $50 filing fee, no annual state report and no annual fee, leaving only the federal Form 5472 and pro forma 1120.

    Five Year State Cost Of A New Mexico LLC

    Over five years, the state-level cost of a New Mexico LLC is a $50 filing fee and nothing recurring, so $50 in total, before the registered agent. That makes New Mexico the cheapest of the five states on this measure. The same arithmetic across the five states runs from $50 to $2,110. For a Portuguese owner, the state fee is small beside the question of how Portugal treats the LLC's income, so plan for a written view from a Portuguese accountant before you form.

    What A New Mexico LLC Costs From Portugal

    Here is the first-year budget for a New Mexico LLC owned from Portugal. State filing: $50 ($50 online). Registered agent: typically $100-150 a year, or included in EasyBrise Global Launch at $295 for year one ($149 a year after that). EIN: free if you apply to the IRS yourself. Bank account: usually free at Mercury or Relay. Recurring state requirement: $0 ever — New Mexico is one of the only states with no ongoing annual report or annual fee for LLCs. Most founders land well under $500 all-in for year one.

    Your Recurring Dates As A Portuguese Owner

    As a Portuguese owner, your recurring dates look like this. State: New Mexico adds no state annual filing at all. Federal: Form 5472 with the pro forma Form 1120 is due on the return due date, April 15 for a calendar-year LLC, extendable with Form 7004. For the one-off EIN call, the IRS line (6 a.m. to 11 p.m. Eastern) is open 11 a.m. to 4 a.m. Portuguese time for most of the year (the gap shrinks to four hours for a few weeks when US and European clock changes fall on different dates). Put the state date and the federal date in your calendar when the EIN arrives, because a missed Form 5472 carries a $25,000 minimum penalty.

    The United States Portugal Income Tax Treaty

    A comprehensive income tax treaty between the United States and Portugal has been in force since the mid-1990s. It covers dividends, interest, royalties and tie-breaker rules for residency. For a typical founder whose LLC earns only non-US-source income, the treaty changes little in practice because there is usually no US federal income tax for it to reduce. It becomes more relevant if the LLC receives US-source income.

    An LLC For Someone Planning To Move To Portugal

    Many founders form the LLC first and move to Portugal later. The LLC and its US filings do not change when you move, but your Portuguese tax position does from the day you become resident. Raise the LLC with a Portuguese accountant before the move rather than after, so that any rule affecting foreign entities, and any choice about special regimes, is dealt with at the right time.

    Portuguese Tax Residence And The Special Regimes

    A person who is tax resident in Portugal is taxed on worldwide income. The Non-Habitual Resident regime stopped accepting ordinary new applications from 2024, and the narrower IFICI regime, often called NHR 2.0, replaced it. IFICI is aimed at listed high-value activities such as scientific research, qualified jobs in certified innovation projects and highly qualified roles, and pensions and passive income such as dividends generally fall outside it. Do not assume a freelancer with a US LLC qualifies. Portugal also has controlled-foreign-company rules in its corporate tax code, so ask a Portuguese adviser how your own structure is treated and ask for the answer in writing.
