PurposeThe study investigates the structure of audit fees in an emerging economy, Jordan.Design/methodology/approachThe following regression model will be tested: ADFEES = f (SIZE, AUST, COMP, INDS, PROF, RISK, YEND, TLAG). The model is tested by running a cross‐sectional linear ordinary least squares (OLS) regression of the audit fees on corporate size, the status of the audit firm, the degree of corporate complexity, profitability, risk, corporate accounting year end and the lag between the audit report and the end of the accounting year.FindingsThe results of the analysis revealed that corporate size, status of the audit firm, industry type, degree of corporate complexity and risk are the main determinants of audit fees. However, variables such as corporate profitability, corporate accounting year‐end (YEND) and time lag between YEND and the audit report date appeared to be insignificant determinants of audit fees.Research limitations/implicationsIn order to generalize the outcome of the study, the same study needs to be conducted over a long period of time (five years). Other variables such as the market share of the audit firm and the economic conditions of the country need to be included in the regression model in future research.Originality/valueThe outcome of the study can be used by audit firms to determine audit fees. Companies' management can also use the results of the study to predict the amount of audit fees that they will pay.
