The role of sustainability reporting in shareholder perception of tax avoidance

The purpose of this study is to examine the moderating effect of sustainability reporting on the relationship between tax avoidance and firm value. This study also examines the moderating effect of sustainability reporting in both environmentally sensitive firms and non-environmentally sensitive firms.

This research uses moderated panel regression with 596 observations and 734 observations for cash effective tax rate (ETR) and generally accepted accounting principles effective tax rate (GAAP ETR) of firms listed on the Indonesian Stock Exchange between 2014 and 2016. Tax avoidance is measured by both cash ETR and GAAP ETR.

This paper shows that sustainability reporting moderates the relationship between tax avoidance (GAAP ETR) and firm value. The results show that GAAP ETR has a negative association with firm value in non-environmentally sensitive firms and a positive association with firm value in environmentally sensitive firms. Consequently, the sustainability report alters only the effect of GAAP ETR on firm value in non-environmentally sensitive firms. The results imply that, unlike environmentally sensitive firms, non-environmentally sensitive firms need sustainability reporting to reduce the reputational costs of tax avoidance.

How shareholders view tax avoidance remains unclear; research on this topic often fails to produce a uniform result. The present research fills this gap by using the existence of sustainability reporting as proof of companies’ ethical motivations to moderate the association of tax avoidance and firm value, which has not been discussed in previous research.
