International tax law

Tax consulting for international companies

Comprehensive advice for international companies

Doing business in an international environment is no longer simply a strategic necessity for major companies; it has now also become an everyday occurrence for many small and medium-sized enterprises.  Many of our clients are also successfully represented in other countries with sales offices and production sites.

We help German companies doing business abroad establish contact with qualified consultants and legal advisors. As active members of the worldwide consultancy network LEA Global, we are in contact with the partners whose expert knowledge you can rely on for your auditing and (transaction related) tax advisory needs. We advise foreign companies on setting up businesses and investing in Germany: choice of location and legal form, structuring, financing, transfer pricing - always taking into account the relevant double taxation agreements.


We consider your situation not only from the point of view of German law, but also according to the regulations of the respective country. In this way, tax risks are minimised and double taxation can be avoided.
