In addition, investors react to the audit committee because it is considered capable of carrying out the supervisory function of management, while investors do not react to independent commissioners and corporate tax policies.   Research, Practical & Social implications: The results of this study encourage entities to increase the role of independent commissioners in carrying out supervisory functions such as the audit committee in order to get a positive response from investors which can increase company value for sustainability business.   Originality/value: In this study, corporate tax policy is measured by reducing the statutory tax rate with a tax compliance ratio that is rarely used in previous studies, resulting in how much corporate tax policy minimizes the tax expense.
