On the other hand, the accountant is an external supervisory unit that performs audits and gives comments based on auditing principles. In order to avoid agency problem, companies can reduce the risk of information asymmetry by establishing internal and external audit systems. In the highly competitive audit market, the accountants can lower the cost of audit by accepting the help of internal auditors or referencing to internal audit work. The study tries to find out whether the number of internal audits and the help of internal auditor influence on audit fees. This study takes public limited companies in Taiwan as research objects. Based on the questionnaires filed by the internal auditors, this study screens the samples from research objects, obtains the number of internal auditors in each sample, realizes whether the internal auditors help the accountants and gets the information of audit fees of the samples in 2017. The empirical research indicates that the number of internal auditors and the help of internal auditors to the accountants have no effect on the audit fees. However, when the accountants come from Big Four accounting firms, the help of internal auditors to the accountant can reduce the audit fees.
