This thesis contributes to the large literature of drivers of tax
avoidance, for example tax system characteristics or the degree of tax
incidence, by investigating which kind of firms drive the discovered
difference in tax avoidance between countries. Thereby, it tries to
answer the question which kind of firms benefit the most from common tax
mechanisms and thus use them the most. By doing so, this thesis focus on
firm characteristics that are not part of the tax system itself, but
rather are common characteristics associated with a difference in tax
avoidance. Moreover, the research is complemented by investigating some
tax related country characteristics to answer the question whether the
observed firm-tax avoidance correlations differ depending on certain
country-specific factors. The thesis therewith further completes the
explanation for the difference between the degree of tax avoidance in
different countries
