Example Scenarios

The case studies presented are solely for the illustration of typical economic and tax law questions in an international context. They are fictional, abstracted scenarios without reference to specific individuals, companies, or mandates.

Company formation with cross-border structuring

A Germany-based entrepreneur plans to enter the U.S. market and establish an operating company. In addition to liability issues, tax challenges arise, particularly with regard to permanent establishment risks, taxation of profits, and future exit scenarios. The task is to develop a suitable corporate and investment structure that complies with both German and U.S. law and is sustainable in the long term. The structure will be implemented in coordination with tax advisors and U.S. lawyers and will be geared towards growth and potential financing rounds.

Cross-border contract drafting between Germany and the USA

A German company is entering into long-term supply and licensing agreements with a US business partner. Due to differing liability standards, tax consequences, and enforcement mechanisms, there is an increased economic risk. The legal task involves structuring a set of contracts with a clear choice of law, enforceable jurisdiction or arbitration clauses, and a tax-aligned risk allocation. The goal is to create legal certainty and minimize potential disputes at the contractual level.

International Tax Structuring in Corporate Restructuring

An internationally active company with operations in Germany and the USA is planning an internal corporate restructuring. Existing participations are to be reorganized and future investments efficiently consolidated. The challenge lies in analyzing the tax implications in both jurisdictions, avoiding double taxation risks, and complying with regulatory requirements. Based on an integrated legal and tax review, a structure will be developed that meets both regulatory requirements and economic objectives.

Frequently Asked Questions

Cross-border advice is particularly useful in situations involving:

International consulting is particularly useful for:

  • Company formations or expansion between Germany and the USA
  • Choice of Legal Form and Tax Structure
  • M&A transactions or investments
  • international contracts and business models
  • Restructurings, funding rounds, or exits

Especially in the early stages, the right structure can avoid significant tax and legal risks.

Why should business and tax law be considered together?

Because legal and tax decisions are inextricably linked. A legally sound corporate structure can be tax-disadvantageous, and vice versa. An integrated approach ensures that structures are consistent, feasible, and sustainable in the long term, under both German and US law.

Do you also work with private individuals, or only with companies?

We advise companies as well as private individuals, particularly entrepreneurs, shareholders, and investors with cross-border structures between Germany and the USA. What is decisive is not the size of the mandate, but its international complexity.

When should one seek legal and tax advice?

Ideally, as soon as possible. The earlier structures, contracts, or transactions are accompanied, the better risks can be avoided and opportunities for strategic development can be utilized. Early advice is almost always more efficient and cost-effective than a later correction.
