US Company Formation from Austria (2026): How Austria Classifies a US LLC, 27.5% KESt, Place of Management, the US–Austria Treaty and the GmbH or FlexCo Subsidiary Route

Austrians ask about US LLCs for the same reasons as everyone else: US clients, US payment platforms, a US address, and the idea of a company that pays no US tax. What makes Austria different is how firmly its own tax law answers the question "what is this LLC?". Austria does not follow the US label. It compares the foreign entity with Austrian legal forms, the Typenvergleich, and for a single-member LLC the answer is almost always that it is a corporation (Körperschaft).

That one conclusion drives everything else: when tax arises, at what rate, whether the LLC itself becomes taxable in Austria, and whether the US–Austria treaty helps. This guide goes through it step by step, then compares US LLC formation with US C-Corp formation for Austrian individuals, Einzelunternehmer, GmbHs and the new FlexCo.

In short: Austrians can own 100% of a US LLC or C-Corporation, formed remotely. Austria classifies a US LLC through the Typenvergleich. A single-member LLC cannot be compared with an Austrian partnership, which needs two partners, so it is generally treated as a corporation. Distributions to an Austrian individual are then taxed at 27.5% KESt, with credit for up to 15% US withholding. If the LLC is managed from Austria, it can be fully liable to Austrian corporate tax (23%). The US–Austria treaty limits US withholding on dividends to 15% (5% for companies owning 10% or more) and exempts most interest and royalties. With UCB, a Delaware corporation with EIN is $358 and a Wyoming LLC with EIN is $249, all-in.

Step 1: what Austria thinks a US LLC is

The Austrian Ministry of Finance (BMF) classifies foreign entities by comparing their legal features with Austrian forms. It looks at the LLC's operating agreement and the state statute: limited liability for all members, central management, continuity independent of members, and the transferability of interests.

• A single-member LLC has no Austrian partnership equivalent, because an OG or KG needs at least two partners. In practice it is treated as a corporation, like a GmbH.
• A multi-member LLC can go either way. An operating agreement that makes it look like a KG (management by members, restrictions on transfer, members personally running the business) may lead to partnership treatment. One that looks like a GmbH leads to corporate treatment.
• A US check-the-box election to tax the LLC as a corporation in the USA does not decide the Austrian answer.

The BMF has refused to give a blanket ruling that every LLC is a corporation. In a case with real money at stake, ask your Steuerberater, and consider an EAS-Auskunft (a ruling from the BMF on international tax questions).

Step 2: what follows if the LLC is a corporation

For an Austrian resident individual who owns a single-member US LLC:

1. The LLC's profits are not your income while they stay in the LLC. Austria does not tax you on them as they arise (Austria's CFC rule, §10a KStG, applies to corporate shareholders, not individuals).
2. Distributions are dividends from a foreign corporation, taxed at the special rate of 27.5% (KESt rate), declared in your income tax return if no Austrian bank withholds it.
3. The US does not withhold on a disregarded LLC's distributions, because the IRS sees no dividend. So there is no US tax to credit, and the full 27.5% is due in Austria.

That is often a perfectly acceptable result: profits taxed at 27.5% when taken out, rather than at progressive rates up to 50% (55% above €1 million) as business income.

The catch: place of management

A corporation whose place of effective management (Ort der Geschäftsleitung) is in Austria is fully liable to Austrian corporate tax at 23%, wherever it was incorporated. A single-member LLC run by its owner from an office in Graz or Linz is managed from Austria. The Finanzamt can treat it as an Austrian-taxable corporation:

• the LLC pays 23% Austrian corporate tax on its profits;
• distributions to you are taxed at 27.5%;
• the combined burden is about 44.2%, much the same as a GmbH, but with the extra cost and complexity of a US company.

So an Austrian who forms a US LLC "to pay no tax" usually ends up, at best, with the GmbH result plus US compliance costs. And if the Austrian tax authorities treat the LLC's income as your own business income instead, the result can be worse.

Corporate owners: §10a KStG

An Austrian GmbH or FlexCo that owns more than 50% of a foreign company with mainly passive income (interest, royalties, dividends, certain financial and leasing income) and a low effective tax rate (12.5% or less) has the foreign company's passive income added to its own. A US LLC that the IRS disregards and that pays no US tax can be a low-taxed foreign company for this purpose. An active trading or services LLC with real substance is generally outside the rule, but it still needs transfer-pricing support.

Step 3: the US–Austria treaty

The treaty in force since 1998 sets these US withholding limits for Austrian residents:

The treaty also limits US tax on business profits to a US permanent establishment. There is a complication with LLCs: because the US treats a single-member LLC as transparent and Austria treats it as a corporation, the treaty's rules on fiscally transparent entities decide who can claim benefits for US-source income received by the LLC. For an Austrian owner of an LLC with no US-source investment income, this rarely matters. For one receiving US dividends or interest through the LLC, take advice.

Austrians are also eligible for the E-2 treaty investor visa, which lets a founder or key employee live in the USA to run a substantial US business.

US LLC formation from Austria

US tax position

The IRS disregards a single-member LLC with a non-resident owner. If the owner works from Austria and the LLC has no US office, employees or dependent agents, there is no US permanent establishment and no US income tax (see effectively connected income explained). The LLC files Form 5472 with a pro forma Form 1120 every year, and the penalty for missing it is $25,000 (see Form 5472 explained).

Einzelunternehmer or US LLC?

These are illustrative figures, not a client case, at €0.92 to the dollar.

Lukas is a freelance software architect in Vienna who earns US$130,000 (about €120,000) a year, mostly from US clients.

• As an Einzelunternehmer, his profit after expenses and the Gewinnfreibetrag is taxed at progressive income tax rates, with SVS social insurance. Two of his clients are content to pay an Austrian sole trader by international wire.
• Through a US LLC managed from Vienna, the LLC is likely to be treated as an Austrian-managed corporation: 23% corporate tax on profit, then 27.5% on distributions. He also pays a Steuerberater for Austrian corporate returns and UCB for US filings. Social insurance still applies to what he pays himself if he is employed by or works for the company.
• Through an Austrian GmbH or FlexCo, he gets the same 23% + 27.5% result, with Austrian legal certainty and bank familiarity.

For Lukas, the US LLC only makes sense if his US clients require a US vendor. Then the cleaner solution is often a GmbH that owns a small US LLC used only for US contracts and payments, with the LLC paying the GmbH for his work.

US C-Corp formation from Austria

US tax position

A US corporation pays 21% federal tax on its profits plus state tax, and files Form 1120 and Form 5472 every year (see the 21% corporate tax explained and the C-Corp guide for non-residents). Under the treaty, its dividends to an Austrian GmbH owning 10% or more are withheld at 5%.

The standard route for Austrian companies

For Austrian businesses expanding to the USA, the usual structure is a GmbH or FlexCo parent with a Delaware corporation subsidiary:

• Austria and the USA classify the corporation the same way, so there is no hybrid mismatch.
• Dividends to the Austrian parent are withheld at 5% in the USA and are generally exempt in Austria under the international participation exemption (internationale Schachtelbeteiligung, for holdings of at least 10% held for at least one year).
• §10a KStG does not apply to an active US subsidiary paying 21% US tax.
• Transfer pricing between the Austrian parent and the US subsidiary must be documented.

Example: a Tyrolean machinery maker

Take an illustrative case: a family-owned machinery manufacturer in Tyrol sells through US distributors and wants its own US sales and service company. It forms a Delaware corporation with a service technician in North Carolina and a sales manager in Illinois.

• The US subsidiary buys machines from the Austrian GmbH at arm's-length prices, sells and services them, and pays US tax on its margin.
• Dividends to the GmbH are withheld at 5% and exempt in Austria.
• If the subsidiary needs funding, an intercompany loan from the GmbH pays interest free of US withholding under the treaty, subject to US interest deduction limits.

Start-ups and the FlexCo

Since 2024, Austria's Flexible Kapitalgesellschaft (FlexCo) has made employee shares easier to issue, and the GmbH minimum capital fell to €10,000. Austrian start-ups that raise money from US investors still usually need a Delaware C-Corporation at the top, through a "flip" in which the FlexCo becomes a subsidiary. A flip has Austrian tax consequences for the founders, including possible exit tax on unrealised gains. See raising US investment as a foreign founder.

Which state

• Delaware for a corporation, a subsidiary or a start-up.
• Wyoming or New Mexico for a small contracting LLC owned by an Austrian GmbH.
• The state where US staff work, which the company must register in.

What it costs

UCB's prices include state fees and the first year of registered agent service:

• Delaware corporation with EIN: $358.
• Wyoming LLC with EIN: $249, or $348 with a US bank account application.

A Delaware corporation costs $578 a year to keep active. A Wyoming LLC costs $121 a year, or $421 with the annual federal return. A US business address with your own suite number is $60 a year. See what a US LLC costs every year.

Documents and banking

For an individual owner, your Austrian passport and a Meldezettel or utility bill. For a GmbH or FlexCo owner, a current Firmenbuchauszug, translated into English, and a resolution approving the US company. US fintech banks accept Austrian owners readily. See US business bank accounts for non-residents and Stripe for non-residents.

Mistakes to avoid

• Assuming Austria treats a single-member LLC as transparent because the IRS does.
• Running a US LLC from Austria and forgetting that its place of management may make it an Austrian-taxable corporation.
• Not declaring LLC distributions at 27.5% because no US tax was withheld.
• A GmbH owning a low-taxed passive US LLC without checking §10a KStG.
• Missing Form 5472 in a year when no US tax was due.
