Yes, residents of Spain can form a Wyoming LLC entirely online without ever setting foot in the United States. The all-inclusive cost through WyomingLLC is $397 (the Wyoming state fee is included), formation completes in about 24 hours, and your EIN and US business bank account follow over the next few weeks. This guide explains exactly how it works from Spain, what it costs, how banking approval really goes, and how the US-Spain tax treaty affects you.
Why a Wyoming LLC for Spain founders
A Wyoming LLC is one of the cleanest legal vehicles a Spanish resident can use to run an international business that bills customers in US dollars. The reasons are practical, not theoretical.
First, pass-through taxation. A single-member Wyoming LLC is a "disregarded entity" for US federal tax purposes. The LLC itself pays no US federal income tax. Profit flows to you, the owner. If none of that profit is effectively connected income (ECI) from a US trade or business — which is the normal situation for a Spanish freelancer, agency, or e-commerce seller operating from Spain — there is no US federal income tax on the business profit. You still have a US information filing obligation (Form 5472, covered below), but not a US tax bill on ordinary foreign-earned profit.
Second, no US physical presence is required. You do not need a US visa, US residency, US citizenship, or a US address of your own. Wyoming law requires every LLC to maintain a registered agent with a physical Wyoming address, and that service is included in the $397. You manage the entire company from Madrid, Barcelona, Valencia, or anywhere else in Spain.
Third, privacy. Wyoming does not publish member or manager names on the public formation record filed with the Wyoming Secretary of State. Compared to many EU registries where beneficial ownership is searchable, this is a meaningful privacy advantage for consultants and creators.
Fourth, asset protection. Wyoming pioneered the LLC in the US in 1977 and has the strongest charging-order protection in the country — for single-member LLCs as well as multi-member ones. A creditor who wins a judgment against you personally generally cannot seize the LLC or force a sale of its assets; the charging order is, in most cases, their exclusive remedy.
Fifth, dollar access and credibility. A US LLC with an EIN and a US bank account lets you invoice US clients, accept Stripe and PayPal under a US entity, sell on US-facing marketplaces, and hold USD without constant conversion. For a Spain-based business serving an English-speaking or US customer base, that combination removes a lot of friction that a Spanish autónomo or SL structure alone would not solve.
The result for most Spanish founders is a low-maintenance, low-cost, dollar-native company that sits cleanly on top of their Spanish tax life rather than fighting it.
Cost from Spain
The headline price is $397, all-inclusive — and critically, the Wyoming state filing fee is included in that number, not added on top. There is no surprise government surcharge at checkout.
| Item | Included in $397? | Notes |
|---|---|---|
| Wyoming state filing fee | Yes — included | Paid to the Wyoming Secretary of State on your behalf |
| LLC formation (Articles of Organization) | Yes | Filed in ~24 hours |
| Registered agent (year 1) | Yes | Required Wyoming physical address |
| EIN (Employer Identification Number) | Yes | Obtained via Form SS-4, no SSN needed |
| Operating agreement | Yes | Single or multi-member template |
| US bank account setup assistance | Yes | Mercury, Relay, or Wise guidance |
| ITIN (Individual Taxpayer Identification Number) | No — separate | Optional $297 add-on, only if you actually need one |
| Year-2 renewal | No — recurring | ~$160/year (see below) |
Most Spanish founders do not need an ITIN to operate. You get an EIN for the company without an SSN or ITIN, and the EIN is what banks, Stripe, and the IRS use. An ITIN only matters in narrower situations (for example certain treaty-based withholding claims or specific filing needs), which is why it is a separate $297 add-on rather than bundled — you only pay for it if it's genuinely useful to you.
Year 2 and beyond: budget roughly $160 per year. That covers the Wyoming annual report / license tax (the Wyoming Secretary of State charges a minimum annual license tax of $60 for most small LLCs) plus the registered agent renewal. There is no US federal income tax in that figure for a non-ECI business — it is purely the cost of keeping the entity in good standing. Compared to the ongoing cost and social-security exposure of some Spanish structures, the recurring overhead of a Wyoming LLC is deliberately small.
Banking after formation from Spain
This is where expectations need to be realistic, because banking is the step that has changed most for non-residents.
Spain sits in a favorable position. It is an EU/EEA, FATF-aligned, low-risk jurisdiction, and that profile genuinely helps you. Mercury, Relay, and Wise all accept Spain-based founders, and Spanish residents are among the more straightforwardly approved European applicants. But "accepted" is not the same as "guaranteed" — through 2025 and into 2026, Mercury and Relay both tightened their non-resident review, and applications are assessed case-by-case.
What they actually check:
- A valid EIN and your filed Articles of Organization (formation documents).
- A real, non-registered-agent US business address or clear operating description. This is the single biggest change: Mercury and Relay no longer accept a registered agent address as the LLC's business address. You describe your real business and, where asked, use an address you legitimately control or a compliant virtual address — not the agent's Wyoming address.
- Your passport and proof of your Spanish residential address.
- A coherent business story: what you sell, to whom, expected volume. Vague or mismatched answers trigger declines more than nationality does.
Recommended fallback order for Spanish founders:
- Mercury — best product (real US bank partners, FDIC insurance via partner banks, clean API/Stripe integration). Apply first. Spain's risk profile is favorable here.
- Relay — strong second choice, also FDIC-insured via partner banks, lets you create multiple sub-accounts (popular with e-commerce sellers managing cash flow).
- Wise Business — the safest fallback because it approves the widest range of applicants. Note Wise is an Electronic Money Institution, not a bank, so balances are safeguarded rather than FDIC-insured — but for receiving USD, EUR, GBP and holding multiple currencies it is excellent, and it rarely declines a clean Spanish-owned US LLC.
The practical playbook: apply to Mercury first; if declined, go to Relay; if both decline, Wise Business will almost always work. Most Spanish founders get approved on the first or second attempt. Budget 8-10 business days after your EIN arrives for the account to open. Never use your registered agent's address as the business address on a bank application — that is the most common avoidable rejection in 2025-2026.
Tax: US and Spain
The US side first. There is a comprehensive, in-force US-Spain income tax treaty. It was signed in 1990 and entered into force on January 1, 1991, and a major modernizing Protocol signed in 2013 took effect on November 27, 2019 (IRS, Spain — Tax Treaty Documents; IRS treaty text). Under the modernized treaty, US-source interest is generally 0%, royalties are 0%, and dividends are 15% (reduced to 5% for a 10%-voting corporate shareholder, and 0% for certain 80%+ holdings and qualifying pension funds). This matters if your LLC ever earns US-source passive (FDAP) income — the treaty can reduce the default 30% withholding. For a typical services or e-commerce LLC with no US-source FDAP and no ECI, there is no US federal income tax on the operating profit at all.
The filing you cannot skip. A foreign-owned single-member Wyoming LLC is a disregarded entity that must file IRS Form 5472 together with a pro-forma Form 1120 every year, reporting reportable transactions between you and the LLC (capital contributions, distributions, etc.). This is an information return, not a tax bill — but the penalty for failing to file, filing late, or filing incomplete is $25,000 (IRS, About Form 5472). Do not treat this casually; it is the one US obligation that catches non-resident owners off guard.
BOI / FinCEN. Per FinCEN's Interim Final Rule of March 26, 2025, domestic US entities — including Wyoming LLCs formed in the US — are exempt from Beneficial Ownership Information (BOI) reporting (FinCEN BOI). You currently have no BOI filing for a US-formed Wyoming LLC.
The Spain side — this is the part Spanish founders most underestimate. Spain does not simply mirror the US "disregarded entity" treatment. Under Spain's international fiscal transparency (transparencia fiscal internacional / CFC) rules, and per Spanish binding consultations on US LLCs, Spain looks through the LLC and attributes its income to you personally as a Spanish tax resident — taxed under your IRPF (personal income tax), and potentially treated as autónomo activity if the LLC is effectively managed from Spain. In other words, being "tax-free in the US" does not make the profit tax-free in Spain. If you are a Spanish tax resident (generally 183+ days/year), you almost certainly owe Spanish tax on the LLC's profit and may owe Spanish social security as an autónomo.
You also have reporting obligations in Spain. If your foreign assets — including a participation in a foreign entity like a US LLC and any US bank balances — exceed €50,000, you must file Modelo 720 (and the newer Modelo 721 for crypto), declaring those assets to the Agencia Tributaria, typically by 31 March for the prior year. Spanish valuation rules for the LLC are strict and differ from US accounting. Get a Spanish gestor or tax adviser before you assume the profit is tax-free at home — the US treatment and the Spanish treatment are genuinely different, and the gap is where people get into trouble. None of this is US tax advice or Spanish tax advice; it is a flag to plan properly.
Popular use cases for Spain founders
A Wyoming LLC fits a specific set of Spanish businesses especially well:
-
E-commerce and dropshipping. Sellers shipping to US and international customers use a Wyoming LLC to hold their store, Stripe/PayPal, and supplier relationships under a US entity. Relay's multi-account feature is popular for separating ad spend, inventory, and profit. Selling into the US under a US LLC also simplifies how marketplaces and payment processors see you.
-
Consulting and freelance services. Spanish consultants, developers, designers, and marketers serving US and global clients invoice through the LLC. US clients are often more comfortable paying a US entity with a US bank account, and you avoid the friction of cross-border invoicing from a Spanish autónomo setup. Because the work is performed from Spain, it is typically not ECI — no US income tax on the profit — though Spanish IRPF still applies.
-
SaaS, digital products, and creators. Software subscriptions, info products, courses, templates, and content monetization (YouTube, sponsorships, affiliate income) run cleanly through a US LLC with USD rails. App stores and ad networks pay US entities smoothly.
-
Tourism and travel services. Spain's huge tourism sector means many founders run booking platforms, tour operations, villa rentals, and travel-content businesses aimed at international (often US) travelers. A US LLC lets them collect deposits and payments in USD and present a US business face to American customers.
In all of these, the pattern is the same: the customers or platforms are US-facing or global, the work is done from Spain, and the founder wants dollar banking, US-entity credibility, and pass-through US treatment — while handling the Spanish side correctly.
Step-by-step: forming from Spain
-
Choose your LLC name. It must be unique in Wyoming and end with "LLC" or "Limited Liability Company." We check availability against the Wyoming Secretary of State business database before filing so your name isn't rejected.
-
Appoint a registered agent. Wyoming law requires a registered agent with a physical Wyoming street address to receive legal and state mail. This is included in your $397 — you do not arrange it separately.
-
File the Articles of Organization. We submit your formation document to the Wyoming Secretary of State. Approval typically lands in about 24 hours. This is the moment your LLC legally exists. Your name is not published on the public record.
-
Get your EIN via Form SS-4. The EIN is your company's US tax ID. As a non-US founder without an SSN or ITIN, we obtain it for you by filing Form SS-4 with the IRS (the "responsible party" is you). This usually takes 8-10 business days for foreign applicants. You need the EIN for banking, Stripe, and your Form 5472 filing.
-
Sign your operating agreement. This internal document sets out ownership, management, and how profits are handled. It is not filed with the state but banks and payment processors ask for it, and it reinforces your liability protection. A template is included.
-
Open your US bank account. With EIN and formation documents in hand, apply to Mercury first, then Relay, then Wise Business as fallback (see the banking section). Use a real business description and a compliant address — never the registered agent's address. Budget 8-10 business days after the EIN.
End to end, expect roughly 3-4 weeks from order to a fully operational, bankable US company. From there, your only recurring US tasks are the ~$160/year Wyoming renewal and the annual Form 5472 + pro-forma 1120 — plus your Spanish IRPF and Modelo 720 obligations at home.
Common mistakes Spain founders make
-
Assuming "no US tax" means "no tax." The biggest error. US pass-through treatment does not exempt you from Spanish IRPF. Spain's CFC/transparency rules attribute the LLC's profit to you, and you may owe Spanish income tax and autónomo social security. Plan the Spanish side from day one.
-
Forgetting Modelo 720. If your US LLC interest plus US bank balances cross €50,000, you must declare them on Modelo 720. Penalties for Spanish foreign-asset non-disclosure have historically been severe — do not skip it.
-
Skipping Form 5472. The US $25,000 penalty for a missed or late Form 5472 + pro-forma 1120 is real and automatic. File every year, even with zero activity, if there were reportable transactions (including your initial capital contribution).
-
Using the registered agent address on the bank application. Mercury and Relay reject this in 2025-2026. Describe your real business and use a compliant address.
-
Buying an ITIN you don't need. Most Spanish founders operate fine on the EIN alone. Only add the $297 ITIN if a specific filing or treaty claim actually requires it.
-
Believing they owe US federal tax on ordinary profit. Without ECI or US-source FDAP, there is generally no US federal income tax — the obligation is the information return, not a tax payment.
