Defining and Managing Corporate Tax Risk: Perceptions of Tax Risk Experts*

Abstract

We examine the "black box" of corporate tax risk management by providing unique insights into practitioners' tax risk perceptions, tax risk management practices, and influences leading to variation in tax risk management practices across firms. Opening this black box is important as tax risk has become an increasingly relevant aspect in corporate tax practice-little is yet known about how firms define and manage tax-related risks. We perform our analysis based on 33 expert interviews, which we conducted with 42 tax risk experts. The first important finding from our interviews is that tax risk is a multifaceted and contextdependent construct, consisting of six tax risk components: financial, reputational, compliance, political, tax process, and personal liability risk. Furthermore, we find that perceived tax risk varies substantially between corporate insiders and corporate outsiders. Our interview insights further reveal that firms' most frequently used tax risk management practices relate to some form of tax communication. The tax departments' rationale for using tax communication as a key tax risk management practice is to protect the firm-in particular, the CFO-from three types of pressure: public pressure, peer pressure, and regulatory pressure. Our analysis has important implications for future studies. First, our insights reveal that several tax risk components are not sufficiently covered by common tax risk measures used by the archival literature. Second, we find that communication has a key role in managing tax risk. This deviates from the purely supportive role that extant risk management frameworks have assigned to communication.

Perceived tax audit aggressiveness, tax control frameworks and tax planning: an empirical analysis

“…Reputational risks can have an impact on tax avoidance (Graham et al 2014) and therefore on the need for skills in the tax department, whose employees need to evaluate and control the tax planning strategies. This finding is also consistent with the effect on communication skills, which represent a very important factor in tax risk assessment (Brühne and Schanz 2022). Furthermore, we find branches, subsidiaries or other permanent establishments in more than 30 countries and 0 otherwise.…”

“…In addition, in our analysis of the impact of a perceived change in audit aggressiveness on TCFI, we assume that a more aggressive audit leads to higher risks and therefore to a demand of more certainty. The TCF acts as a protective shield (Brühne and Schanz 2022) and therefore mitigates potential monetary risks from the stricter enforcement. However, again one objection might be that there is a potential risk of reverse causality.…”

Driving financial results is not the only priority! An exploration of the future role of chief financial officer: a grounded theory approach

“…CFOs are responsible for understanding and mitigating the organization’s risks and establishing and maintaining adequate risk management and mitigation systems. It is common for the CFO to be in charge of all aspects of the company’s treasury and risk management (Graham and Harvey, 2001; Hecht, 2021; Brühne and Schanz, 2022; Tillema et al , 2022). CFOs have assumed the company’s custodian role, ensuring that risks are identified, assessed, managed and integrated into the corporate strategy.…”
