Industry specialization and tax avoidance in the Australian banking industry

Abstract

Purpose The purpose of this study is to examine the impact of industry specialization of audit partners and audit committee members on the level of tax avoidance in Australian banks. Design/methodology/approach This study uses a multivariate regression analysis based on hand-collected data consisting of 180 observations from Australian domestic banks between 2010 and 2018. Findings The primary results of the empirical analysis indicate that audit partner industry specialization is negatively associated with the level of tax avoidance in Australian banks. Regarding the audit committee, the proportion of industry specialists among audit committee members reduces the magnitude of tax avoidance. These results are robust, as they hold the same for alternative measures of tax avoidance and industry specialization of audit partner and audit committee members. Results from supplementary analysis reveal that the interactive effect of both audit firm and audit partner industry specialization strengthens the auditors’ effectiveness in reducing the level of tax avoidance. Practical implications As this study highlights the importance of the industry specialization in decreasing tax avoidance, it can be beneficial for policymakers to assess the impact of good governance on the level of tax avoidance in the banking industry. Originality/value Even though the existing studies examine the link between the governance actors’ industry specialization and tax avoidance in nonfinancial firms, this paper explores the banking industry that differs from nonfinancial firms in among others; accounting and fiscal regulations. This study further provides unique evidence indicating that industry specialization of the audit partner constitutes a significant determinant of minimizing the bank’s level of tax avoidance.
