EU Inc vs US LLC: Which Is Better for Your Startup?
Comparing EU Inc with US LLC for international founders. Tax implications, banking, scalability, and practical considerations.
Edited by the EU Inc Guide editorial board. Independent, data-driven analysis.
The US LLC has become the default structure for a certain kind of internationally-minded founder: low cost, flexible, and blessed by the American legal and financial ecosystem that much of the tech world runs on. The EU Inc is the proposed European counterpart: a pan-EU company form designed to be just as straightforward to register and just as useful across 27 countries.
They solve different problems for different markets. Here is what you actually need to know to decide between them.
The US LLC: what you're actually getting
A US Limited Liability Company is a state-level entity, not a federal one. Every state has its own LLC statute, fees, and requirements. The two states that dominate for non-resident founders are Wyoming and Delaware.
Wyoming LLC has become popular for international founders: no state income tax, no requirement to list members publicly, low annual fees (around $60), and a formation cost typically between $50–$150 for the state filing fee alone. Third-party registered agent and formation services (Stripe Atlas, Firstbase, doola) typically bring the total to $100–$500 depending on what's included.
Delaware LLC is the traditional choice for venture-backed companies and anything that might seek institutional investment. Delaware's Court of Chancery handles business disputes with specialised expertise built up over a century of case law, and most US VCs expect Delaware C-corps or LLCs. Formation is similar in cost to Wyoming but annual franchise taxes and report fees are higher.
How a US LLC is taxed (and why this matters more than you think)
This is the part that trips up non-US founders. Badly.
By default, a single-member LLC is a "disregarded entity" for US tax purposes, meaning the IRS taxes the owner directly, not the company. For a US resident, this is straightforward. For a non-resident, it creates layers of complexity that the formation services marketing conveniently glosses over.
Here is a concrete scenario. You're a Turkish developer living in Lisbon, billing US clients through a Wyoming LLC. You chose Wyoming because a YouTube video said "0% state tax" and a formation service made it look like filling out a web form. Your company is registered, you have an EIN, and you're invoicing $8,000 a month to three American SaaS companies.
Effectively Connected Income (ECI): Because your clients are in the US and you're performing services that generate US-source income, the IRS may classify your income as "effectively connected" to a US trade or business. That triggers US federal income tax obligations even though you have never set foot in Wyoming.
The definition of "engaged in a US trade or business" is broader than you might expect. It depends on where your customers are, where services are performed, where decisions are made, and whether you have any US-based personnel or infrastructure.
FATCA reporting: The Foreign Account Tax Compliance Act creates reporting obligations for non-US persons with US financial accounts. Your Wyoming LLC has a Mercury bank account. Mercury reports to the IRS. Your Portuguese bank, under FATCA's reciprocal agreements, may also report your US financial connections to Portuguese tax authorities. You now have reporting obligations on both sides of the Atlantic that you probably did not budget for.
Your home country's claim: Portugal taxes residents on worldwide income. Your US LLC is a pass-through, meaning Portugal's tax authority (Autoridade Tributária) treats the LLC income as your personal income directly. No deferral. No corporate veil. The $96,000 your LLC earned this year is your personal taxable income in Portugal, and Portugal wants its share regardless of what the US does or doesn't tax.
The cascade: You may owe US federal tax on ECI. You owe Portuguese income tax on worldwide income. You have FATCA reporting obligations in both directions.
You need a US tax preparer who understands non-resident LLC taxation and a Portuguese tax advisor who understands how to credit US taxes paid. The $200 Wyoming LLC formation fee has generated several thousand dollars in annual compliance costs.
None of this makes a US LLC wrong for non-residents. Many people use them successfully and the structure genuinely makes sense for certain profiles. It means you need an accountant who understands the cross-border implications before you proceed, not after.
US LLC banking: the door that keeps closing
Until 2023 or so, opening a US LLC and plugging in Mercury or Brex for banking was the standard playbook. A formation service would handle the paperwork, and within a week you had a US company with a US bank account accepting Stripe payments.
That era is ending.
Mercury has become significantly more selective about non-resident accounts. They require more documentation, take longer to approve, and close accounts more readily when compliance flags appear.
Relay, another popular option, has similar tightening. Brex has pivoted away from small startups entirely.
The underlying driver is plain. US banks face regulatory pressure around anti-money-laundering compliance, and non-resident LLC owners with no US address, no US social security number, and no US business activity sit in the highest-effort category to serve.
Stripe Atlas bundles formation with banking access through a partner bank, which smooths the process but costs more (around $500 all-in) and ties your banking relationship to your formation provider.
A consistent pattern among non-resident LLC owners confirms this trajectory. Mercury and Relay have both closed accounts of foreign-owned LLCs during routine compliance reviews, sometimes with as little as 30 days' notice and no clear path to reinstatement.
Opening a replacement account typically requires an ITIN. If you have never filed a US tax return, that means submitting a W-7 application that takes 7 to 11 weeks to process.
Many traditional US banks still require an in-person branch visit, which is not a realistic option for founders who have never been to the US.
The reality: if you are a non-US founder without an ITIN, without a US address, and without plans to visit the US regularly, maintaining a US banking relationship is becoming a genuine operational risk, not just an inconvenience.
Accounts get frozen. Compliance reviews arrive without warning. And when a US bank closes your account, you have 30 days to find another one, which is hard when every other bank runs the same compliance checks.
Factor this into your decision heavily. A company without reliable banking is a company with a serious problem.
EU Inc: what you're actually getting
EU Inc, officially proposed by the European Commission on March 18, 2026, is a company form at the EU level, designed to work uniformly across all 27 member states. The proposal puts the formation cost at under €100 and the registration time at 48 hours, with fully digital registration and no minimum share capital requirement.
The core value proposition is EU single market access without the complexity of 27 different national company law regimes. Register once, operate in every EU country with the same legal entity, under the same rulebook.
Important: EU Inc is not yet available. The European Commission proposal is in the legislative process as of early 2026. The realistic expectation is 2027–2028 before it becomes available in member states. What's available today for EU-based founders is a national company form: Estonian OÜ, Dutch BV, Irish Ltd, German GmbH. EU Inc is the proposed solution to the fragmentation problem those create.
How EU Inc would be taxed
EU Inc differs fundamentally from the US LLC's pass-through model. EU Inc itself does not come with a specific tax regime. You register in a member state, and that member state's corporate tax rules apply.
Register your EU Inc in Ireland: 12.5% on trading income. Register in Germany: roughly 30% effective rate. Register in Estonia using the Estonian implementation: likely the distribution-based system where retained earnings are taxed at 0%.
EU Inc is a legal form, not a tax optimisation tool in itself. The tax outcome depends on where you register and whether you have genuine substance there. The EU Inc tax explained guide goes deeper on this.
The key difference from the US LLC is that the tax relationship is transparent from the start. You know which country's rules apply. You know the rate.
There is no multi-layered analysis of whether your income is "effectively connected" to a trade or business in a country you have never visited.
EU Inc banking: a different picture
The EU banking ecosystem for EU-registered companies is fundamentally different from the US banking situation for non-resident LLC holders.
EU neobanks like Wise Business, Revolut Business, Qonto, and Holvi routinely serve EU-registered companies held by non-EU residents. The EU banking for founders guide covers this in more detail.
The compliance infrastructure is built around EU anti-money-laundering directives, which these banks are designed to handle. Opening a business account for an Estonian OÜ or a Dutch BV through these platforms is a documented, repeatable process with predictable timelines.
Will EU Inc companies have the same access from day one? That depends on how quickly banks update their onboarding processes to recognise the new entity type. Early adopters may hit onboarding delays as banks learn the structure. But the underlying compliance framework is the same, and the incentive for EU neobanks to serve EU Inc companies is obvious.
Compare that to the US, where a non-resident LLC holder is swimming against the regulatory current. The direction of travel matters as much as the current state.

When a US LLC makes sense
You're primarily serving US customers or the US market. A US LLC means you accept US payments without friction, contract under US law where your customers are comfortable, and appear local to a market that prefers local entities. If 70%+ of your revenue comes from American companies, the US LLC is the natural home for that business.
You're raising money from US investors. US VCs strongly prefer US entities. Sequoia, a16z, Y Combinator all default to Delaware C-corps. If a Series A from a US fund is on your roadmap, your structure needs to accommodate that from the start. A US LLC can be converted or restructured, but the earlier you set up correctly, the simpler it is.
You have US-based team members. Running payroll, issuing equity, and handling benefits for US employees is dramatically simpler through a US entity. Employing US workers through a foreign company creates its own complexity: permanent establishment risk, withholding obligations, and benefits administration that no EU payroll provider handles natively.
You want the benefits of US legal infrastructure. Delaware's Court of Chancery has more than two centuries of corporate case law. That matters for sophisticated contracts and investor agreements, even if you're not a US company in any other sense.
Proceed knowing you'll need proper cross-border tax advice. The formation cost is low. The ongoing compliance cost is real.
If you've concluded a US LLC fits your case, Clemta handles Wyoming or Delaware formation including EIN, registered agent, and bank-account application support. The Essentials plan is $349/year plus state fees (Wyoming filing $100 one-time, $60/year annual report). Pricing is transparent; the harder problem is verifying your banking path before you commit.
When EU Inc makes sense
You're building for EU customers. An EU entity invoicing EU clients in euros, operating under EU law, with EU banking. The overhead disappears. No currency conversion costs, no questions from EU procurement departments about foreign entity status, no reverse-charge VAT complications from invoicing across the Atlantic.
Consider the contrast. A French enterprise client receives an invoice from a Wyoming LLC. Their accounts payable department needs to handle USD conversion, verify the entity exists in a US state registry they have never used, and figure out reverse-charge VAT treatment for a non-EU supplier. The same client receives an invoice from an EU Inc. It looks like every other EU supplier invoice they process.
You want to operate in multiple EU countries without the paperwork. This is EU Inc's core structural advantage over both national EU forms and the US LLC. No branch registrations in each country. No local legal entities. No repeated compliance with 27 different national company law regimes. One entity, continent-wide.
Your team is EU-based. Payroll, employment contracts, and benefits for EU employees run cleanly through an EU entity. Employing EU workers through a US LLC creates cross-border employment complexity and potential permanent establishment exposure that can trigger corporate tax obligations in the employee's country.
You care about EU regulatory alignment. GDPR, the AI Act, the Digital Markets Act. The EU regulatory framework increasingly shapes how software and services are built globally.
Operating as an EU entity from the start means designing for compliance rather than retrofitting it later. For data-intensive businesses, having your corporate domicile inside the EU simplifies data processing agreements and cross-border transfer mechanisms considerably.
You've outgrown the sole-proprietor or US LLC default and hit recurring banking friction. Founders running remote operations often default to Stripe Atlas or a freelance setup until revenue clears $150,000 to $200,000 for two or three years.
That is usually when the friction starts costing real money. Mercury asks for residency documentation it did not need at first. Wise flags accounts whose director country and billing country diverge. Stripe holds payouts longer for non-resident directors.
If two of those three apply to you and your revenue justifies the structure, the question is no longer whether to incorporate. It is which jurisdiction.
The pattern reads cleanly: if your revenue, your team, and your regulatory environment are European, an EU structure removes complexity that a US LLC would create.
The tax question everyone has
The implicit assumption in many "US LLC vs EU entity" comparisons is that the US LLC wins on taxes for non-residents. Pass-through treatment, the argument goes, combined with tax treaties, lowers the effective rate. This is often wrong in practice.
The real picture changes sharply depending on where you live. The table below sets out three common scenarios.
| Scenario | US LLC tax exposure | EU entity tax exposure |
|---|---|---|
| US-resident founder | Pass-through to personal return at marginal rate. Familiar territory for US accountants. | Foreign corporation rules apply. Form 5471 reporting and GILTI inclusion under section 951A pull foreign income into your US return. Estimated +$1,500 to $3,000 per year in compliance cost. |
| EU-resident founder | Your country taxes the LLC income as personal income, often with no foreign tax credit available because the US collected nothing at the entity level. FATCA reporting on top. | Local corporate tax applies cleanly. Estonia's 0% retained-earnings rate is real and useful. Dividends are taxed personally when distributed. |
| Non-resident remote founder (third country) | High complexity. Possible ECI exposure if customers are US-based. Home country still claims worldwide income. Banking access tightening fast. | Cleaner one-to-one tax relationship between you and the member state where the company is registered. Substance rules apply but are documentable. |
Neither structure is a magic tax shield. The actual outcome depends on your home country's treaty network, how your income is classified, and whether your setup passes substance scrutiny.
The only reliable answer is advice from an accountant who has handled your specific country combination.
The Form 5471 and GILTI layer (US founders read this)
If you are a US person and own more than half of an EU operating entity, the IRS treats it as a Controlled Foreign Corporation. Two reporting obligations apply that most "tax is irrelevant" comparisons skip.
Form 5471 is the annual information return for US owners of foreign corporations. Late or missing filings carry a $10,000 penalty per year, per entity, before any tax even enters the picture.
GILTI under section 951A pulls the foreign entity's tested income up to your personal US return, less a 50% deduction where applicable, and applies your marginal rate.
For a US founder in the 32% bracket who runs $300,000 in profit through an Estonian OÜ, that is roughly $48,000 in US federal tax annually, before state tax. Estonia's 0% corporate tax does not offset this. There is no foreign tax credit to claim against income Estonia did not collect.
The point is not that EU incorporation is a bad choice for US founders. It is that the tax math for a US person looks structurally different from the math for a South African, Indian, or Nigerian founder.
The GILTI calculator lets you plug in your own numbers and see the effective rate before you commit to a structure.
Compliance cost for the Form 5471 and GILTI reporting layer typically runs $1,500 to $3,000 per year for a competent US accountant. Bake that into the comparison.
Which structure fits you?
The answer depends on three things: where your customers are, where your team is, and which financial ecosystem you want to operate in.
The bottom line
For most non-US founders building for the European market: the US LLC offers little that justifies the tax complexity and banking headaches. A current EU national entity (the Estonian OÜ is the most common choice for remote-first founders today) is more practical now, with EU Inc being the logical evolution once it's available.
For founders targeting the US market or seeking US institutional investment: the US LLC or Delaware C-corp is the right structural move. Get cross-border tax advice on the implications for your home country.
For founders who need both markets: you're probably looking at two entities eventually: a US entity for the US side and an EU entity for the EU side. That's a common structure at scale, and there are service providers who handle exactly this setup. EU Inc won't change this calculus dramatically; it will make the EU side simpler to manage across countries, but it doesn't eliminate the fundamental difference between US and EU legal and financial infrastructure.
The US LLC vs EU Inc comparison is a market question as much as a legal one. Where are your customers? Where is your team? Where do you want to build?
Structure follows strategy. Not the other way around.
Frequently asked questions
Should I register a US LLC or an EU Inc?
It depends on where your customers and team are. A US LLC makes sense if you primarily serve US customers or seek US investor funding. EU Inc is designed for founders building for the European market who want EU-wide legal presence without managing 27 different national company law regimes.
What are the tax differences between a US LLC and EU Inc?
A single-member US LLC is a pass-through entity — the IRS taxes the owner directly, which creates complexity for non-US founders through ECI rules and FATCA reporting. EU Inc uses the member state's corporate tax rate where you register (e.g., 12.5% in Ireland, 0% on retained earnings in Estonia). The tax relationship is more transparent with an EU entity.
Can a non-US founder open a US LLC bank account?
It is becoming increasingly difficult. US banks like Mercury and Relay have tightened requirements for non-resident accounts, closing accounts during compliance reviews with as little as 30 days' notice. Without an ITIN and US address, maintaining a US banking relationship is an operational risk.
Do I need both a US LLC and an EU entity?
If you need both the US and EU markets, you may eventually need entities in both jurisdictions. Start where your largest revenue concentration is. EU Inc will make the EU side simpler to manage across countries but does not eliminate the need for a separate US entity for US operations.
Do I pay US tax if I run my Wyoming LLC from outside the US?
Possibly. The IRS may classify your income as Effectively Connected Income (ECI) to a US trade or business if your customers are US-based, even if you have never visited the US. ECI triggers US federal income tax obligations. Talk to a cross-border tax preparer who handles non-resident LLC filings before incorporating.
Does Estonia's 0% retained-earnings rate work for US founders?
Not directly. If you are a US person owning more than half of an EU operating entity, the IRS treats it as a Controlled Foreign Corporation. GILTI under Section 951A pulls the entity's tested income into your personal US return, and Form 5471 reporting is required, with $10,000 per-year penalties for late filing. Compliance cost typically runs $1,500 to $3,000 per year.
When will EU Inc actually be available?
EU Inc was officially proposed by the European Commission on March 18, 2026, and is moving through the EU legislative process. The realistic expectation for availability in member states is 2027 to 2028. Today, founders use national forms like the Estonian OÜ, Dutch BV, Irish Ltd, or German GmbH.
Which is better for a startup raising venture capital?
US VC funds strongly prefer US entities. Sequoia, a16z, Y Combinator, and most institutional funds default to Delaware C-corps. If you are planning to raise from US institutional investors, a US LLC or Delaware C-corp from the start is the cleaner path. EU Inc has not yet established VC recognition.
