계속감사기간과 조세전략의 지속가능성의 관계

[Purpose]This study analyzes the relationship between auditor’s tenure and sustainable tax strategies. Since the determination of taxable income based on accounting profits can be closely related to the quality of financial reporting, the ongoing audit period can affect the quality of taxable income as well as the quality of financial reporting. [Methodology]This study uses 2,591 firm－year samples listed in the KSE from 2003 to 2017. As a dependent variable, we use the sustainable tax strategies using 5－year coefficient of variation in the cash effective tax rate following McGuire et al.(2013). To test hypothesis, the model includes auditor’s tenure and BIG auditor as an independent variable. [Findings]Followings are the findings of the study. First, effects of the auditor’s tenure on the sustainable tax strategies are significantly negative, indicating that sustainable tax strategy improves as auditor’s tenure increases. Second, coefficient estimates on the BIG auditor are significantly negative, indicating the BIG auditor improves the sustainable tax strategies compared to the non－BIG auditor. Finally, coefficients estimates on the interaction terms of auditor’s tenure and the BIG are significantly positive. This indicates that the longer the audit period, the effects on the sustainable tax strategies are more pronounced for non－BIG auditor than for BIG auditor. [Implications]This study contributes to the extant literature by showing the relationship between the auditor’s tenure and the sustainable tax strategies and extends area of related studies about various factors that determine the corporate tax strategy linked from financial reporting.
