Abstract: This study investigate the relationship between voluntary audit rotation by the two both level (partner/firm) on the audit quality and analyzing the relationship between audit tenure and the audit quality on the Iraq Stock Exchange using a sample of 138 firm year observations for the period 2015-2017. We found a significant positive relationship between voluntary firm rotation and the absolute value of discretionary accruals which means a significant negative relationship between voluntary firm rotation and audit quality. In addition we found a significant negative relationship between audit tenure and the absolute value of discretionary accruals which means a significant positive relationship between audit tenure and audit quality.In addition, we found no relationship between voluntary partner rotation and audit quality which means voluntary partner rotation doesn’t have an effect on the audit quality.
