Setting Up a GmbH in Germany: A Guide for US Founders

Short answer: US citizens can form and own a German GmbH under the same general framework as any non-EU founder. The German formation process, notarisation, capital deposit, and Handelsregister registration, takes four to eight weeks. What makes the US founder's situation distinctive is not the German side of the formation but the US-side compliance obligations that attach to owning a foreign corporation: FBAR, Form 5471, and the GILTI provisions of the US tax code. These do not prevent German company formation, but they require a US international tax advisor to be engaged early. For founders planning to relocate to Germany, the § 21 AufenthG self-employment permit process is the same for US citizens as for other non-EU nationals.

Why US founders choose Germany

Germany is the EU's largest economy and the most frequent European landing point for US companies building international operations. Common reasons include:

EU market access. A German GmbH is an EU legal entity that contracts freely across all 27 member states, participates in EU public procurement, and employs staff under EU employment law. For US businesses whose European growth strategy requires a credible local presence rather than a remote-sales-only approach, a German entity is often the preferred structure.

Sector fit. Germany leads in automotive, industrial machinery, chemicals, pharmaceuticals, enterprise software, and professional services. US founders in engineering, B2B technology, fintech, and consulting frequently find that German enterprise clients require a European counterpart entity for contracting and compliance purposes.

Talent. Germany has approximately 45 million people in the workforce, strong engineering and technical education, and, particularly in Berlin, Munich, and Frankfurt, a growing international tech talent pool. For US founders who want to build a European engineering or operations team, Germany offers depth of qualified candidates.

Relocation. US entrepreneurs who want to live in Germany and build their business there use the GmbH as the vehicle and the § 21 AufenthG permit as the visa pathway. Germany's quality of life, central EU location, healthcare system, and comparatively lower cost of living than major US cities attract a growing number of American founders.

The formation process: US-specific steps

The core process is covered in detail in our GmbH formation guide. For US founders, the following steps require additional preparation:

Apostilles on US documents. The US joined the Hague Apostille Convention, and US public documents submitted in German legal proceedings can be authenticated by apostille. The most common situation where this arises is a power of attorney (Vollmacht): if a US founder sends a representative to the German notary rather than attending in person or using video notarisation, the power of attorney must be notarised in the US and then apostilled. Apostilles are issued by the Secretary of State's office in the state where the document was notarised. Processing times vary significantly by state, from same-day in some states to four to six weeks in others; an expedited service is often available. Passports used for identity verification at the notary do not require apostilling.

Video notarisation. Since 2022, German notaries can conduct standard GmbH formations (using the Musterprotokoll) by video call. US founders using this route connect with a German notary via an approved video platform, present identity documents on camera, and complete the notarisation remotely. Not all notaries offer the video service; confirm availability and their technical requirements before scheduling. Video notarisation eliminates the need to travel to Germany for the incorporation step.

Bank account opening. German corporate bank accounts are opened in the GmbH's name, and the share capital deposit must be made before the Handelsregister entry. For US founders with no prior German banking relationship, expect additional onboarding documentation including proof of address, source of funds for the capital deposit, business purpose, and in some cases a background summary. See the FATCA section below for bank-specific context.

Timeline. Allow ten to fourteen weeks for the full formation process as a US founder, accounting for apostille processing, bank onboarding, and Handelsregister review. Earlier planning of the apostille and bank account steps reduces this significantly.

US tax obligations on a German GmbH

This is where the US founder's situation diverges most clearly from other nationalities, and where specialist advice matters most. The following is a summary of the relevant frameworks; the rules are complex and change.

FBAR: Foreign Bank Account Reporting

US persons, including citizens, green card holders, and residents, must file FinCEN Form 114 (the FBAR) if they have a financial interest in or signature authority over foreign financial accounts with an aggregate value exceeding $10,000 at any point during the calendar year. A US founder who is the sole shareholder and managing director of a German GmbH typically has signature authority over the GmbH's corporate bank account. That account is reportable regardless of whether the founder has any personal interest in the balance.

FBAR is filed electronically through the FinCEN BSA E-Filing System, separately from the US federal tax return. It is due by April 15 of the year following the calendar year being reported, with an automatic extension to October 15 (no application required). Penalties for non-willful failures to file are up to $10,000 per year; willful violations carry substantially higher penalties.

Form 5471: Information Return for US Persons with Foreign Corporations

US persons who own 10 percent or more of a foreign corporation are required to file IRS Form 5471 annually as part of their US federal income tax return. For a US citizen who is the sole shareholder of a German GmbH, this means filing Form 5471 every year. The form is informational in nature but substantial in scope. It requires reporting the GmbH's balance sheet, income statement, accumulated earnings and profits, details of transactions between the GmbH and the shareholder or other related parties, and GILTI-related information.

Failure to file Form 5471 when required triggers an automatic penalty of $10,000 per year, with additional penalties for continued failures after IRS notice. These penalties apply even if no tax is owed.

GILTI: Global Intangible Low-Taxed Income

GILTI was introduced by the Tax Cuts and Jobs Act of 2017 under § 951A of the Internal Revenue Code. It requires US shareholders of Controlled Foreign Corporations (CFCs) to include a deemed portion of the CFC's income in their US taxable income each year, regardless of whether any dividend is distributed from the foreign company.

A German GmbH wholly owned by a US citizen qualifies as a CFC. The GILTI calculation is complex, but the practical effect can be summarised: US founders may owe US tax on German GmbH profits in the same year those profits are earned, even if the money stays in Germany.

To illustrate with a simplified example: a German GmbH earns €100,000 net profit. German combined corporate tax of approximately 30 percent leaves €70,000 in the company after German tax. That €70,000 becomes the starting point for the GILTI calculation (adjusted for the deemed tangible income return on qualified business assets). If no tangible assets exempt a portion, the full €70,000 may be a GILTI inclusion for the US shareholder. The German tax paid can be credited against the US GILTI tax, but individuals face restrictions on the foreign tax credit that C-corporations do not, making the credit less effective for individual shareholders.

The Section 962 election. Individual US shareholders can elect under § 962 of the IRC to be taxed on GILTI at the corporate rate (currently 21 percent) rather than at individual rates (up to 37 percent), and to use indirect foreign tax credits against the GILTI tax in a way that approximates the treatment available to C-corporations. This election is made annually and requires the foreign tax credit calculations to be done carefully. For US founders earning significant profits in a German GmbH, the § 962 election can substantially reduce the GILTI tax burden. Whether it makes sense depends on individual circumstances and requires advice from a US international tax specialist.

The US-Germany Income Tax Treaty

The bilateral income tax treaty between the US and Germany, in force in its current version since 1990 with subsequent protocols, addresses double taxation on various income types. Key provisions include reduced withholding tax on dividends (5 percent for corporate shareholders holding at least 10 percent of the paying company's shares; 15 percent otherwise), allocation of taxing rights over business profits, and relief mechanisms for income taxed in both countries.

The treaty can reduce the withholding tax on dividends when the GmbH distributes profits to a US shareholder. It also provides a framework for determining which country taxes salary income, interest, and royalties. However, the US worldwide taxation system and the GILTI regime interact with the treaty in ways that are not always straightforward, and treaty relief does not eliminate all US tax obligations arising from GmbH ownership.

State taxes

Most US states that impose an income tax tax residents on worldwide income, meaning that German GmbH profits that flow through to the US founder's return may also be subject to state income tax. California, New York, and New Jersey have particularly complex rules for residents with foreign income. Some states do not conform to federal GILTI rules, meaning the state-level treatment can differ from the federal treatment. US founders who are state residents with a German GmbH should verify their state-level obligations with a tax advisor familiar with that state's rules.

FATCA and German banking

The Foreign Account Tax Compliance Act (FATCA) requires German financial institutions to identify US account holders and report relevant account information to the German tax authority (Bundeszentralamt für Steuern), which shares it with the IRS under an intergovernmental agreement. German banks comply with FATCA, but the additional administrative burden of US-person accounts means some banks decline to open accounts for US citizens or apply extended onboarding procedures.

Banks with stronger US-person track records include Deutsche Bank and Commerzbank, both of which have US relationships through their own operations. HSBC Germany is another option. Some regional Sparkasse branches apply stricter policies and may decline US-person accounts.

Digital banks. N26 Business, Qonto, and Penta are generally more accessible and do not systematically exclude US founders. For initial account opening, a digital bank is often the practical starting point while a traditional account is being established in parallel.

What to prepare. German banks onboarding US-person corporate accounts typically request: certified passport copy, proof of residential address, a completed FATCA self-certification (W-9 equivalent), source of funds documentation for the share capital, description of the company's business, and in some cases documentation of corporate structure and beneficial ownership. Assembling this documentation before approaching the bank speeds up the process.

The US-Germany Social Security Totalization Agreement

The US and Germany have a Social Security Totalization Agreement in force since 1979. Its primary purpose is to prevent double payment of social security contributions for workers who spend time in both countries.

For founders: a US citizen who moves to Germany and runs their German GmbH as managing director will typically be subject to German social insurance contributions, including health insurance (Krankenversicherung), pension (Rentenversicherung), and other branches. The totalization agreement allows periods of insurance in both countries to be combined when calculating benefit entitlements. Managing directors of their own GmbH are sometimes exempt from mandatory German pension and unemployment insurance depending on ownership and control structures; a German Steuerberater or employment law specialist can clarify the position for the specific setup.

Healthcare

Germany has a dual-track health insurance system. The statutory system (gesetzliche Krankenversicherung, GKV) covers most employed individuals and self-employed persons below certain income thresholds. The private system (private Krankenversicherung, PKV) is available to those above the income threshold or to the self-employed who elect it. Both systems require mandatory enrolment for German residents.

For US founders relocating to Germany, health insurance enrolment is part of the Anmeldung (resident registration) process. US health insurance coverage typically does not satisfy German requirements. A German insurance broker can advise on PKV options, which for working-age healthy adults are often financially comparable to or cheaper than equivalent US private coverage.

Relocating to Germany: the § 21 AufenthG permit

US citizens do not require a Schengen visa for short stays in Germany of up to 90 days in any 180-day period. For long-term relocation to operate a business, a residence permit is required. The § 21 AufenthG self-employment permit is the standard route for non-EU founders.

US citizens apply at a German embassy or consulate in the US. Major German diplomatic missions are located in Washington DC, New York, Chicago, Los Angeles, San Francisco, Houston, Boston, and Atlanta. The requirements are the same as for all non-EU applicants: a viable and detailed business plan demonstrating economic interest for Germany, adequate financing covering business operations and personal living costs, and qualifications and professional experience relevant to the planned activity.

In practice, US founders applying for the § 21 AufenthG tend to have straightforward applications provided the business plan is strong and the financial documentation is clean. A well-capitalised GmbH, a credible business plan, and documented personal financial resources are the foundation of a successful application. IHK assessment of the business plan is often requested by the authority and adds credibility to the application.

Timeline. Embassy appointment availability and permit processing add two to six months beyond the company formation timeline. Starting both processes in parallel is advisable.

Popular locations for US founders

Berlin is the most internationally oriented German city and has the most established English-language startup ecosystem. Housing is more affordable than Munich, the international community is large, and a strong English-speaking professional network exists for founders who do not yet speak German. Several major US tech companies have Berlin offices.

Munich offers the strongest access to industrial and enterprise clients in automotive, aerospace, and engineering, and is a short flight from most major European cities. It is more expensive than Berlin but has a large English-speaking expat community and strong connections to international capital.

Frankfurt is Germany's financial centre and the European home for many US financial institutions. For US founders in fintech, asset management, or professional services, Frankfurt's financial infrastructure and international business community can be advantageous.

Hamburg has strengths in logistics, media, and trade, and is a well-functioning, internationally-connected city with a significant English-speaking population.

How S&S Consult helps
