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...

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...

Tax uncertainty often negatively affects investment. Advance tax rulings (ATRs) are commonly used as a measure to provide tax certainty. Rulings are currently controversially discussed in the context of tax planning activities of multinational firms (Luxembourg Leaks). We analyze ATRs as tax...

I investigate how investors value tax planning and tax uncertainty for the case of publicly listed German firms. I compare two recent approaches how to account for tax uncertainty: the separate view by Drake et al. (2019) and the composite view by Jacob and Schütt (2020) to find the better...

This study examines a setting in which a tax reporting decision is delegated to a firm 's tax manager. Using financial accounting measures of tax expense to evaluate the tax manager allows the fi rm to efficiently attain the level of tax avoidance it prefers, despite the fact that the...

We use a proprietary data set with detailed executive compensation information to examine the relationship between the incentives of the tax director and GAAP and cash effective tax rates, the book-tax gap, and measures of tax aggressiveness. We find that the incentive compensation of the tax...

A growing literature examines how a firm's behavior impacts the behavior of its peers. In this paper, we examine how changes in tax paying, and the associated financial reporting, impact a firm's peers. Changes to tax paying and reporting behavior at other firms within a peer group can be...

We evaluate whether, and under what circumstances, corporate tax aggressiveness influences audit pricing. Using a compound measure of two long-run effective tax rates, we find that tax aggressive firms pay higher fees for external audit services after controlling for factors related to earnings...

I develop a unifying conceptual framework of corporate tax planning. The framework accommodates constructs frequently studied in empirical tax accounting research, i.e. tax avoidance, tax aggressiveness, tax sheltering, and tax evasion, by relating them to the seminal notion of effective tax...
