The purpose of this paper is to test the influence of tax avoidance on earnings management and earnings’ quality. A`nd, the relationship between tax avoidance and reported earnings was verified by considering factors that do not converge for long periods of time. The difference between tax income and accounting earnings difficult to maintain over time with one direction. As tax income cannot be reported consistently below or above earnings, both are likely to converge for long periods of time. The relation between tax income and earnings implies the relation between tax avoidance and earnings management. Tax avoidance is an interim allocation of tax income and earnings management is an interim allocation of accounting earnings. Tax avoidance and earnings management cause differences between tax income and earnings, which cannot last. Therefore, tax avoidance would also not be able to continue with different directions. It is difficult to reconcile tax avoidance that lowers tax income with earnings management that increases accounting earnings over the long term. On the other hand, tax income and earnings may not be converged over the long term by taxation items such as permanent differences and income deductions. Because these items are not related to interim allocation of tax income, it is likely that the relation between tax avoidance and earnings management will be significant only for aggressive tax avoidance. That is because aggressive tax avoidance can reduce differences over time by aggressive earnings management. Under aggressive tax avoidance, earnings management will also be increased and earnings’ quality will be reduced. Earnings management was measured in discretionary accounting accruals and the absolute value of discretionary accounting accruals was interpreted as earnings’ quality. Tax avoidance was measured under the model of DesaI and Dharmapala(2006). Test period was from 2008’ to 2015’, and samples were selected from listed manufacturing companies. The empirical results were as follows. First, tax avoidance showed a significant positive impact on discretionary accounting accruals. This means that the greater the tax avoidance on tax income, the greater the earnings management on reported earnings. Second, the absolute value of tax avoidance showed a significant positive impact on the absolute value of discretionary accounting accruals. This means that the larger the amount of tax avoidance, the lower the quality of earnings. Third, aggressive tax avoidance has shown that earnings management is greater and earnings’ quality is lower. This means that the relation between tax avoidance and earnings is mainly due to aggressive tax avoidance. Because of tax items that do not resolve the difference between tax income and earnings, tax avoidance will affect earnings management in the case of active tax evasion. This study distinguishes between earnings management and earnings’ quality with discretionary accounting accruals. This study separated the impact of tax avoidance on earnings management and on earnings’ quality. In particular, the relation between tax avoidance and earnings management or earnings’ quality was confirmed by aggressive tax avoidance. As there are a variety of measures for earnings management and tax avoidance, further analyses will be needed to determine whether the results of this study can be supported for these variables.
