Business Taxation

Business Taxation

Website of the institute


Business taxation examines the problems that arise for companies from the existence of taxes. In particular, the decision-makers should be able to assess operational facts from a tax perspective, make decisions taking into account the resulting tax effects and develop alternative courses of action to achieve the determined goals while avoiding negative tax effects. A prerequisite for this is a well-founded knowledge of tax law.


The institute is involved in the business education of undergraduate and graduate students. The imparting of tax law knowledge plays an important role without, however, being the focus of the subject. Rather, the focus is on tax planning and the economic analysis of tax effects. For example, the effects of taxation on investment and financing behavior in a national and international context are worked out and the tax-optimized legal form and location are discussed.
