감사품질이 세무 보고이익을 고려한 회계선택에 미친 영향

This study aims to provide empirical evidences about the relationship between audit quality and accounting choices considering the changes in taxable income. According to the argument by Badertscher et al.(2009), managers make their decision for accounting choices comparing tax and non tax costs, which means that systemic difference in accounting choices may exist whether taxable income is influenced by the accounting choices or not. Also, Hanlon et al.(2005, 2006) argue that qualities of accounting information may be affected by managers' tax reporting preference, which induce the reduction in ERC and earnings persistence. Based on these arguments, we may expect that differences of audit quality may contribute to the incremental information role of external audit for financial market thereby, audit quality will have the positive relation with book tax conformity accruals. Also, If external audit stands for the degree of monitoring forces, managers will reduce the book only accruals mainly due to the high detection costs that book-tax differences have. Taken together, we may suggest incremental implications that not only for the high quality of external audit may play an important role in delivering information contents which accruals have, but also for managers to differentiate their accounting choices. This may have an affect on the book tax differences in order to minimize the non tax costs such as detection cost and financial reporting pressure in the stock market.
