Yes, residents of Mexico can form a Wyoming LLC entirely online without visiting the United States. The all-inclusive cost through WyomingLLC is $397, which already includes the Wyoming state filing fee, your registered agent for year one, and the EIN application. Formation completes in about 24 hours, your EIN follows in 8-10 business days, and a US business bank account (Mercury, Relay, or Wise) takes another 8-10 days after the EIN arrives.
Why a Wyoming LLC for Mexico founders
A Wyoming LLC gives a Mexican founder a clean, dollar-denominated US business identity without the cost, capital requirements, or notary overhead of incorporating a Mexican S.A. de C.V. or even a simplified S.A.S. For founders selling to US customers, running e-commerce, consulting for US clients, or invoicing platforms like Stripe, Amazon, Upwork, and Gumroad, a US LLC is often the single requirement that unlocks payment processing that simply does not accept a Mexican sole proprietor (persona física con actividad empresarial).
The structural advantages that matter most for Mexico residents are:
Pass-through taxation with no US tax on foreign-source income. A single-member LLC is a "disregarded entity" for US federal tax purposes. If your LLC has no Effectively Connected Income (ECI) and no US dependent agent or office, the US generally does not tax your business profits. You earn in dollars, and US federal income tax on operating profit is typically zero. (Your Mexican obligations are separate and real — covered in the tax section below.)
No US physical presence required. You never need to fly to the US, get a visa, or rent a US address. Your $397 package includes a Wyoming registered agent who provides the required in-state address and receives official mail on your behalf. Wyoming itself has no state corporate income tax and no state personal income tax.
Privacy. Wyoming does not publish member or manager names in its public Articles of Organization filed with the Wyoming Secretary of State. For a Mexican founder concerned about personal-security exposure that can come with publicly listing business ownership, this matters.
Strong asset protection. Wyoming pioneered the LLC in the US in 1977 and offers the country's strongest charging-order protection, meaning a creditor of a member generally cannot seize the LLC or force distributions — they are limited to a charging order against distributions actually made.
Proximity and currency. Mexico shares a land border, overlapping time zones, and the deepest trade relationship of any US partner under the USMCA. A US LLC lets a Mexican entrepreneur hold and settle in USD, hedge peso volatility, and serve cross-border clients with a banking and tax address that US counterparties recognize instantly.
Lower friction than a Mexican entity. Standing up a Mexican S.A. de C.V. typically means a notario público, minimum capital, a fideicomiso in some cases for foreign-facing activity, and ongoing accounting and CFDI e-invoicing obligations from day one. A Wyoming LLC, by contrast, is formed online in about 24 hours with a single $397 payment and no minimum capital. For a founder whose customers and processors are American, the US LLC is the structure those counterparties already understand — there is no need to explain a foreign corporate form to a US bank, a US client's accounts-payable team, or a payment processor's compliance reviewer.
Cost from Mexico
Everything required to launch is bundled into one $397 payment. There is no separate Wyoming state fee to pay later for formation — it is already inside the $397. The only meaningful recurring cost is the year-two renewal.
| Item | Year 1 (at signup) | Year 2 onward |
|---|---|---|
| Wyoming state filing fee | Included in $397 | — |
| Registered agent (Wyoming) | Included in $397 | ~$100 |
| EIN application (no SSN needed) | Included in $397 | — |
| Operating agreement | Included in $397 | — |
| Wyoming Annual Report (license tax) | — | ~$60 (min) |
| Total | $397 all-inclusive | ~$160/year |
The Wyoming Annual Report carries a minimum license tax of $60 for LLCs with under $300,000 of assets located in Wyoming (which describes virtually every non-resident online business), per the Wyoming Secretary of State. Combined with registered agent renewal of roughly $100, your steady-state cost is about $160 per year. The optional ITIN service ($297) is a separate add-on you only need if you personally must file a US individual return or claim certain treaty benefits — most single-member LLC owners with no ECI do not need an ITIN to operate.
Banking after formation from Mexico
Mexican founders are in a relatively strong position with US fintech banking compared to higher-risk jurisdictions, but 2025-2026 has not been business-as-usual. Mercury and Relay both tightened non-resident onboarding through 2025 and into 2026, and a key change is that Mercury and Relay no longer accept a registered-agent address as the LLC's US business address — they want to see a genuine operating address, and newly formed entities with zero revenue are scrutinized more heavily (sources: Globalsolo, Foreign Founder, Corporatee 2026 comparisons).
What the platforms check at onboarding:
- Your EIN confirmation letter (CP-575) or 147C
- Wyoming Articles of Organization
- Your passport and proof of address in Mexico
- A clear description of your business model and expected transaction flow
- Increasingly, whether your US "business address" is a real address rather than the registered agent's
Realistic approval picture for Mexico:
| Provider | Type | Mexico reality |
|---|---|---|
| Mercury | US fintech (banking via partner banks) | Accepts Mexican founders; expect identity verification and a clear business-description step. Strongest as a primary operating account when approved. |
| Relay | US fintech | Similar profile to Mercury; occasionally asks for additional documentation. A reasonable second option, not a guaranteed fallback. |
| Wise Business | Multi-currency money platform | The most reliable to approve from Mexico. Not a bank, but gives USD account details, low-cost USD/MXN conversion, and fast onboarding. |
Recommended fallback order: apply to Mercury first; if you face friction or extended review, apply to Relay; keep Wise Business as the dependable safety net. Many Mexican founders run Mercury (or Relay) as the primary US operating account and Wise alongside it for cheap peso conversion and international transfers — the redundancy is the point. If both Mercury and Relay stall, Wise alone is enough to receive USD from Stripe, clients, and marketplaces and to move money home. We provide approval-prep guidance and help you reapply if needed.
A few practical tips that materially improve approval odds from Mexico: apply only after your EIN letter is in hand (never before); write a specific, plain-language business description that names your customers and revenue source rather than a vague "consulting"; have a clean PDF of your Articles and signed operating agreement ready to upload; and use a consistent name and address across every document so the platform's automated checks line up. Avoid logging into the application repeatedly from different IP addresses or VPNs, which can trigger manual review. If you are asked for an SSN by Relay, that is the automated flow defaulting to a US-person path — respond through support that you are a non-resident applying with an EIN. Patience helps: a Mexico application that goes to manual review often clears within one to two weeks rather than being rejected outright.
Tax: US and Mexico
Verified US treaty status. The United States and Mexico have a comprehensive income tax treaty that is in force. It was signed September 18, 1992, entered into force January 1, 1994, and has been amended by protocols (1995 and 2003). The treaty appears on the official IRS Mexico tax-treaty documents page and in the IRS tax treaty tables. Under the treaty's withholding articles, US-source dividends are capped at 5% (for a corporate owner of at least 10% of voting stock) or otherwise 15%/10%, interest is generally capped at around 10% (with a reduced 4.9% rate for banks and exemptions for certain government interest), and royalties are capped at 10% (sources: IRS Mexico Tax Treaty Documents, IRS Tax Treaty Tables, the US-Mexico Income Tax Convention PDF at irs.gov).
Important nuance: treaty withholding relief applies to US-source FDAP income (dividends, interest, royalties). For a typical Mexican founder running an active online business through a single-member LLC, the operating profit is services/business income, not FDAP, and if it is not Effectively Connected Income, the US generally does not tax it at all — so the treaty rates rarely come into play on ordinary operating revenue. Where they matter is passive US-source income (e.g., US dividends or US-situated royalties). If your LLC genuinely has ECI — a US office, US employees/dependent agents, or US-based inventory operations — that profit becomes US-taxable and you should engage a US CPA.
Mandatory US federal filing regardless of tax owed. A foreign-owned single-member US LLC is treated as a disregarded entity but must file IRS Form 5472 attached to a pro-forma Form 1120 every year to report transactions between the LLC and its foreign owner (including capital contributions and distributions). This is an information return, not a tax return, but the penalty for failing to file is $25,000 per Form 5472, per the IRS. This obligation exists even if the LLC earned nothing and owes no US tax. See our Form 5472 guide.
Your Mexican obligations are the real exposure. This is where Mexican founders must be careful. Mexico does not recognize US "tax transparency" — Mexican domestic law treats a foreign entity (including a US LLC) as an opaque legal entity for Mexican tax purposes, not as a pass-through. More importantly, Mexico operates an anti-deferral CFC regime known as REFIPRE (Régimen Fiscal Preferente). Income earned through a foreign entity that is taxed at less than 22.5% (i.e., 75% of Mexico's 30% corporate rate) is generally treated as a "preferential tax regime," and a Mexican-resident controller must include that income on their annual Mexican return even if it is not distributed, plus file the annual informative REFIPRE return in February. Because a US LLC owned by a non-resident often pays little or no US tax, it can fall squarely inside REFIPRE. Translation: forming the LLC does not make the income invisible to the SAT — you owe Mexican tax and disclosure on it. Work with a Mexican contador to file the REFIPRE informative return and report the income correctly (sources: ICLG Private Client Mexico, DLA Piper on Mexican disclosure rules). Nothing here is individual tax advice.
A practical way to think about it: the Wyoming LLC solves your US-side problem (legitimate US business identity, US banking, US payment rails, minimal or zero US federal tax on non-ECI) and your US filing obligation (Form 5472), but it does not eliminate your Mexico-side obligation. Build your compliance around three calendar anchors — the annual US Form 5472 filing (generally due with the pro-forma 1120 by April 15, extendable), the Mexican annual personal return, and the February REFIPRE informative return — and keep contemporaneous records of every contribution to and distribution from the LLC, since those are exactly the transactions Form 5472 and the SAT both want to see.
Popular use cases for Mexico founders
Mexican entrepreneurs typically form a Wyoming LLC to plug into US-facing revenue rails that a domestic Mexican structure cannot easily access:
- E-commerce and dropshipping. Selling on Amazon US, Shopify, or Etsy to US buyers. A US LLC + EIN unlocks Amazon Seller Central as a US entity, US payment processing, and cleaner supplier relationships.
- Cross-border consulting and agencies. Marketing, design, software, and professional-services firms invoicing US clients in dollars. US companies are far more comfortable paying a US LLC than wiring pesos to an individual abroad.
- Stripe / SaaS / digital products. Stripe, Paddle, and similar processors onboard a US LLC with an EIN smoothly. SaaS founders, course creators, and digital-product sellers use the LLC to collect global subscription revenue in USD.
- Freelancing on US platforms. Upwork, Fiverr, Toptal, and direct US clients — the LLC provides a professional billing entity and a US bank account to receive payouts.
- Real estate and investment holding. Some Mexican founders use a US LLC as a holding vehicle for US-facing ventures or investment activity. Note that direct US real estate ownership triggers its own FIRPTA and US filing rules — get specific advice.
- Affiliate and content monetization. Receiving USD payouts from US affiliate networks, ad networks, and sponsorships.
The common thread: the LLC is the credential that lets a Mexican founder be treated as a US business by US platforms, processors, and clients.
Step-by-step: forming from Mexico
- Choose your LLC name. Pick a name ending in "LLC" and check availability against the Wyoming Secretary of State business database. We verify availability for you before filing so your formation is not rejected on a name conflict.
- Appoint a Wyoming registered agent. Wyoming law requires every LLC to maintain a registered agent with a physical Wyoming address. This is included in your $397 — you do not arrange it separately.
- File the Articles of Organization. We prepare and file your Articles with the Wyoming Secretary of State. Wyoming does not require member names on the public filing, preserving your privacy. Approval is typically within 24 hours.
- Obtain your EIN via Form SS-4. Because you have no US Social Security Number, the EIN cannot be issued through the IRS online tool. We file Form SS-4 for you (by fax/mail as a third-party designee), which is the standard route for non-residents without an SSN. Expect the EIN in about 8-10 business days. See our EIN-without-SSN guide.
- Sign your operating agreement. Your single-member operating agreement (included) governs ownership and management and is what banks and processors ask to see. Keep a signed PDF.
- Open your US business account. With your EIN letter, Articles, operating agreement, and passport in hand, apply to Mercury first, then Relay, with Wise Business as your reliable fallback. Budget another 8-10 business days for approval and funding.
End to end, most Mexican founders are fully operational — formed, EIN in hand, and banking live — in roughly 3-4 weeks from placing the order.
Common mistakes Mexico founders make
- Assuming the LLC hides income from the SAT. It does not. Mexico's REFIPRE/CFC regime can require you to report and pay Mexican tax on the LLC's income even if undistributed, plus file the February informative return. Plan for your Mexican contador from day one.
- Skipping Form 5472. The most expensive US mistake. Every foreign-owned single-member LLC must file Form 5472 + pro-forma 1120 annually; missing it is a flat $25,000 IRS penalty even with zero revenue.
- Using the registered agent address as the bank "operating address." Mercury and Relay now reject this. Have a real, explainable business address ready.
- Confusing "no US tax" with "no tax anywhere." No US tax on non-ECI is true federally, but your Mexican income tax and disclosure obligations remain fully in force.
- Treating the treaty as a magic exemption. The US-Mexico treaty caps withholding on passive US-source income; it does not exempt your ordinary operating profit (which is usually non-taxable in the US for a different reason — no ECI). Do not file treaty claims you do not need, and do not assume relief you have not confirmed with a CPA.
- Forgetting the Wyoming Annual Report. Miss the annual report/license tax (~$60 minimum) and your LLC can be administratively dissolved by the Wyoming Secretary of State. We track this for you.
