This study focuses on manufacturing companies listed on the Indonesia Stock Exchange (IDX) for the 2015-2018 period. Using the STATA 13 regression data panel, this study shows that capital intensity has no significant effect on tax avoidance and inventory intensity has no significant effect on tax avoidance. However, this study found that industry auditors' specialization had a positive effect on tax avoidance.
