His technical expertise as well as his empathetic, open and engaging manner are highly sought after by his clients.

He specialises in international and national tax law as well as procedural tax law, in particular criminal tax law. Among other things, he advises on tax-optimised asset allocation, restructuring of assets and business groups, succession planning taking into account all personal aspects of families and their members, cross-border mobility of private individuals, business tax planning, (self-disclosure) declarations, complex tax audits as well as appeal and fiscal court proceedings. Due to his openness to technology, he is very familiar with digital business models.

Dr. Ottenwälder has been working for many years as a lecturer at various universities in Germany and abroad, for which he has also been honoured with a teaching award. He also regularly gives lectures in Germany and abroad, is the author of numerous specialist articles, commentaries (Foreign Tax Act), podcasts and is an active member of the International Bar Association.

Dr. Ottenwälder previously worked for seven years at POELLATH (Counsel), Frankfurt, and four years at Ebner Stolz (authorised signatory), Hamburg, both in tax law. He studied business administration at the University of Bayreuth (specialising in tax and finance) and completed his Ph.D. in 2014 on the topic of ‘Cross-border divisions of corporations within the European Union’ under Prof. Dr Jochen Sigloch. In the same year, he also passed his tax advisor exam.
