How to Set Up a US LLC from Czechia (2026 Guide)

A US LLC gives Czech founders access to US customers, Stripe, and dollar banking, but it also creates a Czech tax question that most guides skip. Here is the full process plus the home-country angle.

Why founders in Czechia open a US LLC

Most Czech founders who look into a US LLC are not trying to avoid Czech tax. They want a US business entity so they can invoice US clients comfortably, get approved for Stripe, Mercury, or PayPal without friction, sell on US marketplaces, or simply present a US address to partners who are used to working with US companies. A US LLC is fast to form, cheap to maintain compared with a US corporation, and does not require you to visit the United States or hold a US visa at any point.

What it does not do is remove your Czech tax residency or your obligation to report worldwide income in Czechia if you are tax resident there. The LLC is a US legal structure. Your personal tax position is decided by Czech law, and the two systems interact in ways worth understanding before you form anything.

The step by step process

1. Choose a state

You do not need to live in, or even visit, the state where you register. Wyoming is the most common default for non-US founders because it has no state income tax, low annual fees, and strong privacy for member details. Delaware is popular with startups that plan to raise venture capital, since investors and lawyers are simply more familiar with Delaware corporate law. New Mexico is sometimes used for its very low costs, though it offers less predictability. For most Czech founders running a services, SaaS, or e-commerce business without VC ambitions, Wyoming is the sensible starting point.

2. Form the LLC

You file articles of organization with the state, appoint a registered agent with a physical address in that state, and adopt an operating agreement that sets out ownership and management. None of this requires a US address of your own or a US co-founder.

3. Get an EIN

The EIN (Employer Identification Number) is what the IRS uses to identify your LLC. Non-residents without a Social Security Number apply using Form SS-4, and this is submitted by fax or mail rather than online, since the IRS online EIN tool is restricted to applicants with a US SSN or ITIN. Processing by fax typically takes a few weeks. Without an EIN you cannot open a US business bank account or file the required annual returns.

4. Get an ITIN, if you need one

An ITIN (Individual Taxpayer Identification Number) is a US tax processing number for people who are not eligible for a Social Security Number. You do not need a US visa to get one, and it is not an immigration document. Not every LLC owner needs one immediately, but it becomes relevant if you personally need to file a US tax return, claim treaty benefits, or if a specific bank requires it. Many Czech founders open their first US bank account before ever needing an ITIN, then apply for one later if their situation calls for it.

5. Open a US business bank account

Fintech-style providers such as Mercury, Wise Business, and Relay allow fully remote onboarding for non-resident founders once you have your formation documents and EIN. Traditional US banks generally still expect an in-person visit, so most Czech founders start with one of the remote-friendly providers and add a card program or a second account later.

6. Stay compliant every year

A foreign-owned single-member LLC is required to file Form 5472 together with a pro-forma Form 1120 every year, even if the LLC had zero income or was completely dormant. This is an information return, it does not calculate or pay tax by itself, but skipping it can trigger a penalty of 25,000 dollars per missed filing. On top of that you will owe the state's annual report and registered agent fee. This is exactly the kind of recurring, deadline-driven paperwork that Founders Credit handles for founders as part of a done-for-you setup, alongside the LLC formation, EIN, ITIN, and bank account steps above.

The Czech tax angle, in plain terms

This is the part most US-focused guides leave out, and it matters more than the LLC formation itself.

Transparent or opaque, according to Czech rules

In the US, a single-member LLC is a disregarded entity by default, meaning the IRS looks straight through it to you. Czech tax law does not automatically copy that US default. The Czech tax administration applies its own comparison test to decide whether a foreign entity is treated as transparent (like a Czech partnership, so profits are taxed directly in your hands as they arise) or opaque (like a Czech s.r.o., so profits are only taxed on distribution, similar to a dividend). The outcome depends on how the LLC's structure compares against features of known Czech entity types, not on how you elected to treat it for US purposes. This classification decides when and how your LLC's profits show up on your Czech return, so it needs a proper answer rather than an assumption.

CFC rules

Czechia has controlled foreign company rules implementing the EU's ATAD directive, but these are generally aimed at Czech corporate taxpayers that control a foreign entity, not at individuals who own a foreign company directly. If you personally, as a private individual, own the US LLC, the CFC rules are less likely to apply to you in the way they would to a Czech company holding the same LLC. This distinction is technical and fact-specific, so it is worth confirming rather than assuming.

Avoiding double taxation

The United States and the Czech Republic have a long-standing double tax treaty, so income should not simply be taxed twice with no relief. In practice, getting this right means matching the entity's Czech classification, any US filings, and the treaty's relief mechanisms correctly, and doing that correctly depends on your specific business, income type, and residency facts.

When to get local advice

Before you form the LLC, or shortly after, talk to a Czech daňový poradce (tax advisor) who has actually handled US LLCs, not just US corporations. Bring your business model, expected revenue, and whether you plan to draw the money out or reinvest it. This single conversation is usually the difference between a clean setup and an unpleasant surprise at tax return time.
