This study investigates the relationship among income tax system reform, earnings management, and corporate governance on the effective tax rate. Taiwan’s government has amended its income tax law and reduced the income tax rate to 17% in 2010, in which the income tax is deflating the effective tax rate. This study further used discretionary accruals to proxy for earnings management behavior, showing that management of a business with more discretionary accruals targets reducing the tax burden through earnings management behavior, with greater earnings management implying a decline in the effective tax rate. Finally, we looked at whether good corporate governance mechanisms can effectively reduce the improper tax planning of earnings manipulation and increase the effective tax rate. We found that the characteristics that help better inhibit management’s earnings management behavior, reduce inappropriate tax planning, and increase the effective tax rate include a higher institutional investors holding ratio with more discretionary accruals, as well as more people who understand the actual operations and have more professional knowledge. |
