한국채택국제회계기준(K-IFRS)의 도입이 기업의 조세회피에 미치는 영향

The purpose of this study is to empirically analyze the effect of adoption of the Korean International Financial Reporting Standards(K-IFRS) on tax avoidance in Korea. To verify changes after the adoption of the K-IFRS in this study, The difference between accounting income and taxable income(Book-Tax Difference, BTD) and the estimated amount of tax avoidance by the Desai and Dharmapala(2006) model has been used as tax avoidance measured value. The result of empirical analysis is as shown below. First, the t-test on the average estimated amount of tax avoidance before and after adoption of the K-IFRS has indicated that the average estimated amount of tax avoidance decreased significantly after adoption of the K-IFRS. Especially after applying the K-IFRS, the average BTD has turned into negative range, indicating that the accounting income is higher than the taxable income. Second, the regression analysis of the effect of the K-IFRS adoption on tax avoidance has indicated that the BTD decreased significantly after adoption of the K-IFRS. Thereafter, the analysis except from the effect of earnings management on the accounting income of business manager on the BTD has also indicated that the BTD decreased significantly after adoption of the K-IFRS. Thus, all BTDs after elimination of effect by earnings management from BTD and BTD have decreased after application of the K-IFRS. However, the negative BTD value of BTD after application of the K-IFRS indicates that the tax adjustment has occurred to increase the taxable income. Considering the fact that a rational business manager pursues to minimize the tax burden, such result comes from the systematical difference between newly applied accounting standards and tax systems instead of aggressive taxation strategy of business manager. In this study, the effect of applying the K-IFRS is to be empirically analyzed to propose the further issues in establishment of taxation policies.
