Employee human capital is a key corporate intellectual asset; thus, employee turnover and salaries are important to corporate human resource management. To strengthen the disclosure of corporate governance information and corporate social responsibility, Taiwanese listed and over-the-counter (OTC) companies are required to disclose information about the salaries of full-time nonmanagement employees. Using the sample of Taiwanese listed and OTC companies from 2010 to 2019, we investigate the relations between employee turnover, salaries of full-time nonmanagement employees, and corporate tax avoidance. We find that firms with higher employee turnover tend to have lower corporate tax avoidance. Further, firms with higher salaries for full-time nonmanagement employees tend to have lower corporate tax avoidance.
