EU Inc vs US LLC: Which Is Better for Your Startup?

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.

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 straightforward: 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 are the highest-friction 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, and if you have never filed a US tax return, that means submitting a W-7 application that takes 7–11 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 not easy 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 — we cover this in detail in EU Inc tax explained. But here is the key difference from the US LLC: 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 — Wise Business, Revolut Business, Qonto, Holvi — routinely serve EU-registered companies held by non-EU residents. (For a detailed look at how EU banking works for founders, see our separate guide.) 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 face some friction 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.

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 are straightforward 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.

The pattern is straightforward: 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 because of pass-through treatment and bilateral tax treaties. This is often wrong in practice.

For a non-resident with a single-member disregarded US LLC:

• Your home country likely taxes you on the LLC income directly as personal income
• If the LLC has US-source income, you may have US federal filing obligations
• FATCA creates reporting overhead on both sides
• The "0% corporate tax" claim is technically true at the entity level but often irrelevant after home-country taxation

For an EU entity (currently a national form like an Estonian OÜ, eventually EU Inc):

• Estonia's 0% retained earnings rate is real and useful for founders who reinvest
• Your home country still taxes you on distributions you take
• Substance rules apply — you need genuine business activity where you're registered
• But the tax relationship is one-to-one: you and the member state where your company is registered

Neither structure is a magic tax shield. The actual outcome depends on your home country's tax 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.

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

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.
