About me – Anke Rosendahl, tax consultant

I have worked in tax consulting since 1992, becoming a tax specialist in 2003 and a tax consultant in 2005. After being a partner in a law office in Munich, I took up a new challenge and moved to Switzerland in 2010.

Here I trained in Swiss tax law and gained initial experience as a freelancer in a Swiss law firm. Along the way I represented my own clients and took the next step into self-employment on 1st April 2014.

The Tägerwilen office was established on 1st August 2014.

In addition to German and Swiss clients, I look after the interests of many international businesses in relation to Swiss tax law.


Development of individual and
creative solutions for
your individual tax
and social security concerns.

Tax consulting

The regulations of tax law are very extensive. There are many decisions to be made, which may have tax implications.
We are well prepared for this challenge.

Cross border

Cross-border tax consulting for Germany and Switzerland, and in respect of international relations. Also support with clarifications of other countries’ DTAs.
