The question of why some companies pay more taxes than others is a widely investigated topic of interest. One of the famous suspect explanations is a phenomenon called tax avoidance. We develop a holistic theoretical concept of influences on corporate tax planning through a series of 19 in-depth...

The question of why some companies pay fewer taxes than others is a widely investigated topic of interest. One of the well-known explanations is a phenomenon called tax avoidance. We develop a grounded theory model of influences on corporate tax planning through a series of 19 in-depth German...

We derive determinants of tax avoidance by means of a multi-task principal-agent model. We extend prevailing models by integrating both corporate and individual income taxation as well as by including tax planning effort in the agent’s action portfolio. Our model shows novel and apparently...

Firms are arguably motivated to exhibit tax aggressiveness because tax constitutes a significant portion of firms' total costs. This study aims to test the effects of IFRS adoption and law enforcement on book-tax aggressiveness in six developing ASEAN countries. Our sample is 29,504 firm-year...

A corporate tax rate cut provides an incentive for corporations to shift taxable income from years before the tax rate cut to post-reform years. Our study analyzes whether depreciations and write-offs are used to achieve intertemporal income shifting. Using a panel of German manufacturing firms,...
