The aim of this thesis is to explore the firm-specific determinants of the demand for tax haven operations by Czech firms. Our objective is to better understand the firms' incentives for tax haven use, and furthermore whether there exists cross-haven heterogeneity in those incentives. The thesis examines the firms' tax haven investment behaviour by analysing firm-level data for 15,530 Czech firms for year 2013. To the extent of our knowledge, this has been the first research of its kind devoted to Czech firms. The evidence suggests that larger, more profitable firms with larger international presence are most likely to use tax havens. The analysis also indicates that higher firm indebtedness is associated with greater likelihood of establishing tax haven operations. This would suggest Czech firms engage in profit shifting through the use of debt financing. Furthermore, service firms were found to be more likely to use tax havens than manufacturing firms. This contrasts with previous research where R&D intensity was a leading indicator of tax haven use. Additionally, we found significant cross-haven heterogeneity in the determinants, particularly in the sector-specific characteristics. In our sample, service firms favoured Cyprus and the Netherlands, while manufacturing firms preferred Luxembourg...

- A comparison of the taxation of income from employment in the Czech Republic and the Federal Republic of Germany The main objective of this thesis is to compare the taxation of income from dependent activities (especially from employment) in the Czech Republic and the Federal Republic of Germany. The thesis consists of an introduction, five chapters and a conclusion. Chapter One is rather theoretical and deals with general terms of the tax theory. The term "dependent activity" is defined in chapter two. Chapter Three compares and contrasts the components of individual income tax in both countries. Chapter Four offers a brief and simplified comparison of the tax burden of an individual in the Czech Republic and the Federal Republic of Germany. The last chapter is concerned with double taxation and its prevention. The tax rate in Germany is higher than in the Czech Republic. Nevertheless, the German tax system takes more into account the individual tax payer's ability to pay taxes as well as his specific social situation. A more complicated tax system like that, however, demands very high standards from the state administration. When an employee is working abroad, it is essential to determine his tax residence - limited or unlimited tax liability - in order to properly calculate his income tax....
