The IFRS adoption, corporate tax avoidance and the moderating effect of family ownership

Abstract

Purpose This paper aims to examine the influence of the International Financial Reporting Standards (IFRS) adoption on corporate tax avoidance (CTA). In addition, this study aims to explore whether family ownership moderates the impact of IFRS adoption on CTA. Design/methodology/approach The authors used a sample of 1,856 firms from various countries around the world, covering the period between 2010 and 2022. To estimate the proposed econometric models, the authors applied both fixed and random effects regression methods. Findings The present findings show that IFRS adoption has a negative impact on CTA, as measured by the effective tax rate and book-tax differences. This negative impact is more pronounced in “common law” countries than in “civil law countries.” Additionally, the authors found that family ownership plays a moderating role by positively affecting the impact of IFRS adoption on CTA. Practical implications The findings have practical, regulatory and academic implications for fostering accountability and fairness in taxation. This study suggests that implementing IFRS reduces tax avoidance and emphasizes the need for firms to evaluate the implications of IFRS adoption on their tax-planning strategies. It highlights the importance of aligning financial reporting practices with international standards to enhance transparency and minimize tax avoidance opportunities. The differential impact of IFRS adoption between “common law” and “civil law” countries underscores the role of legal and regulatory frameworks. In addition, family ownership plays a significant role in shaping tax-planning strategies. From an academic perspective, this research provides a foundation for further exploration into the relationship between IFRS adoption and tax avoidance. Originality/value The existing literature has predominantly concentrated on examining the effect of IFRS adoption on CTA, and the empirical findings have been inconsistent. This study introduces a novel perspective by considering the moderating influence of family ownership in determining the impact of IFRS adoption on CTA.
