German companies looking to expand their business operations into the USA face a fundamental structural decision early on: should market entry be achieved through an independent US subsidiary success or over a Dependent US permanent establishment (branch) German society?

Both models are legally permissible and established in practice, but differ significantly with regard to taxation, liability, and operational implementation. The right choice depends largely on the specific business strategy, risk appetite, and tax objectives.

The US subsidiary is a separate legal entity under US law (typically a Corporation or LLC). It is fully subject to US taxation.

The federal corporate income tax rate is currently 21 % (since the 2017 tax reform). In addition, if applicable State taxes, depending on the company's location

A key advantage of this structure is that the subsidiary is generally taxed independently and no immediate tax liability arises for the German parent company.

In addition, payments to the German parent company, such as royalties, interest payments, or management fees, can be considered within the scope of international transfer pricing rules. However, these must designed to be user-friendly and carefully documented to be recognized for tax purposes.

A tax burden at the level of the parent company regularly arises only upon Profit distributions (dividends). Here, withholding taxes come into play, which can often be reduced by the German-American double taxation treaty.

A central aspect in practice is the clear separation between the German parent company and the US subsidiary. If this separation is not consistently maintained, there is a risk that the German company itself will be considered as taxable permanent establishment in the USA classified, resulting in additional taxation.

Typical risk factors include:

• Use of Business Premises of the Subsidiary by Employees of the German Parent Company
• operating activities of the parent company in the USA over longer periods
• underdocumented project or support services

The following constellation is particularly critical: If an employee of the German company has the authority to, To conclude contracts in the name of the parent company, and does he carry out this activity in the USA regularly abroad, this can lead to the establishment of a U.S. permanent establishment. The term „regularly“ is interpreted broadly in practice and can be assumed even with repeated use.

Alternatively, a German entrepreneur in the USA can use a Permanent establishment act. In this case, the German company itself remains the taxpayer.

Taxation in the U.S. is based on „effectively connected income“ (ECI). The U.S. federal corporate tax rate (21%) and, where applicable, state taxes apply; in addition, there is often a Branch Profits Tax, which is economically similar to a withholding tax on profit repatriation.

One advantage of this structure is that Losses incurred by U.S. operations can under certain circumstances be offset against profits in Germany., which can be particularly attractive in the startup phase.

However, there are also clear disadvantages, such as limited options for tax structuring (e.g., with license or interest payments), complex allocation of costs between Germany and the US, and increased requirements for accounting separation.

Besides tax aspects, liability is a central factor when choosing a structure.

During the US subsidiary liability is generally limited to the assets of the subsidiary. The German parent company is only indirectly affected. In the case of US Branch whereas the German company is directly liable for all liabilities and risks in the USA.

Especially in the US market, which is characterized by increased procedural risk, this represents a significant disadvantage.

Both the subsidiary and the permanent establishment raise the issue of double taxation. German-American Double Taxation Agreement Here, mechanisms are offered for relief, particularly for the crediting of foreign taxes and the reduction of withholding taxes.

However, the specific application is complex and requires careful coordination between German and US tax planning.

The decision between a subsidiary and a branch is not purely a formal matter, but has far-reaching Consequences for taxes, liability, and operational flexibility.

Early and well-informed planning is crucial to avoid tax risks, strategically manage liability, and create a viable foundation for entering the US market.
