Dr Magnus Müller



Magnus, a German Rechtsanwalt, tax advisor and certified tax lawyer (Steuerberater, Fachanwalt für Steuerrecht), has broad experience in national and international tax matters.  His key practice area is Tax Dispute Resolution. He represents clients across business sectors, predominantly financial institutions, with regard to disputed tax positions, both vis-à-vis tax authorities and criminal prosecution authorities in case of criminal law implications.

Magnus acts for clients at all stages of procedures, ranging from tax filing and assessment procedures to tax audits and contentious administrative appeal and court procedures. He specifically focuses on negotiating consensual settlements with the competent authorities in order to avoid lengthy procedures (Alternative Tax Dispute Resolution). 

He also focuses on Tax Compliance matters, typically involving multi-jurisdictional teams from several practice groups (including Corporate, Regulatory and Litigation). His expertise comprises advice on complex internal investigations and guidance on external investigations conducted by tax and tax investigation authorities as well as the development, implementation and monitoring of appropriate measures of Tax Compliance in order to minimize tax risks (Tax Risk Management). 

In addition, Magnus advises clients on tax-related issues arising in the context of M&A transactions, pre- and post-M&A reorganisations and financing transactions on a regular basis.

Magnus is a lecturer at both the University of Passau and the University of Cologne (LL.M. Business Taxation programme).
