| Summary: | 碩士 === 國立中央大學 === 會計研究所 === 101 === The purpose of this research is to explore whether client firm’s tax aggressiveness leads its auditor to charge higher fees. We expect that when a client firm exposes to higher tax risk, its auditor will charge more audit fees due to the resulting higher audit costs and unanticipated risks. Our sample covers 2008-2011 all A-share firms listed on the Shanghai stock exchange. We follow Simunic’s (1980) audit pricing model and add five additional tax avoidance variables, including cash effective tax rate, book effective tax rate, four-year cumulative cash effective tax rate, book-tax difference, and residual book-tax difference. We find that higher level of the client firm’s tax avoidance leads its auditor to incur higher costs and risks and thus causes auditor to charge higher fees.
