Tax avoidance: do board gender diversity and sustainability performance make a difference?

Purpose This study aims to investigate whether board gender diversity and sustainability performance influence tax avoidance.

Design/methodology/approach The study is based on a sample consisting of 300 UK firms over the 2005-2017 period. This study is motivated by structural equations and system models that specify both a direct and an indirect link between board gender diversity and tax avoidance.

Findings The results show that the level of tax avoidance decrease when the level of women on the board increase. Therefore, we find that sustainability performance is generally associated with greater tax avoidance. In combination, the results suggest that board gender diversity and sustainability performance play a significant role in corporate tax avoidance.

Practical implications The findings may be of interest to the academic researchers, investors and regulators. For academic researchers, it is interested in discovering board gender diversity, sustainability performance and tax avoidance. For investors, the results show that the existence of female directors on the board reduces the tax avoidance. For regulators, the results advise the worldwide policy makers to give the importance of female roles to improve the engagement firms in sustainability reporting.

Originality/value This study extends the existing literature by examining the mediating effect of sustainability performance on the relationship between board gender and tax avoidance in the UK context.
