Abstract This study investigates the influence of corporate board attributes, such as board size, board independence, board meeting frequency, female representation on board, and audit committee size, on tax avoidance. Moreover, the study also explores the moderating role of institutional ownership on these relationships. We use sample of non‐financial firms listed on Pakistan Stock Exchange over the period 2013–2020. Using the framework of agency theory, we report that board size, board independence, board meetings, gender diversity, and audit committees are associated with lower tax avoidance, and the presence of institutional ownership further strengthens these relationship. To test the hypotheses, ordinary least squares regression analysis is applied and robustness is ensured through by employing Generalized method of moments estimation. Overall, our study offers novel insights into the positive implication of board attributes on tax avoidance, particularly within the framework of institutional ownership settings.
