Abstract
This research aimed to discuss whether firms have changed their tax
avoidance activities after
adopting the International Financial Reporting Standards (IFRSs). Moreover, this
research firstly used the two factors (auditor
industry specialization and auditor’s client importance) to
confirm whether the auditor’s characteristics have the impact on the tax avoidance
activities of audit client; then the comparative analysis was conducted before and after the
implementation of IFRSs to understand whether auditor’s attitude has the
different impacts on clients’ tax avoidance
due to the implementation of IFRSs. The research results showed that firms have the more positive
tax avoidance activities after adopting IFRSs. The research also found that the
auditor industry specialization has the positive assisting impact on
clients’ tax avoidance; if the relative importance of audit client to auditor is
higher, the auditor will alleviate the clients’ tax
avoidance. After the IFRSs being adopted, there
are more sufficient evidences showing that the
auditor is helpful to the clients’ tax
avoidance, but when auditors faced more important audit clients,
the impact of supervising tax avoidance has the weakening trend. This research
achievement has verified that the implementation of IFRSs will change the tax
avoidance behavior of firms and auditors.
