This paper aimed to analyze the effect of Key Audit Matters disclosure on Audit Report Lag in Turkey and the relationship between Audit Report Lag and some auditor and firm characteristics. SPSS 28 program was used to test the hypotheses by applying the dependent and independent t-tests, ANOVA method and the Kruskal Wallis Test. The addition of the Key Audit Matters section in the audit report in order to strengthen the communication of the auditor via audit reports is considered one of the important regulations made in recent years. In order to understand the impact of Key Audit Matter reporting on Turkish companies, the results of the 2016 and 2017 financial statements of the companies other than the financial companies in BIST 100 were compared. This comparison revealed that the inclusion of Key Audit Matters in audit reports does not affect audit report lag. In the study, some variables including Key Audit Matters were examined for the purpose of identifying the determinants of audit report lag. Results, which are consistent with some literature, showed that ROA had a significant negative influence on audit report lag. No significant relationship was found between audit report lag and other variables including size, auditor firm, and auditor gender.
