This research examines the impact of board reforms on audit fees and financial restatements in the Iranian capital market. In this context, data from 115 companies listed in the market were analyzed using panel data and logistic regression methods. Board reforms, as a key aspect of corporate governance, can influence transparency and the quality of financial reporting. The results indicate that enhancing information transparency and strengthening internal controls can reduce the likelihood of financial restatements, potentially leading to lower audit fees. Furthermore, establishing strong relationships between the board and auditors can facilitate the audit process and decrease costs. Finally, recommendations for future research are provided, including exploring the impact of board reforms in other countries and analyzing the role of environmental factors in this relationship. This study can contribute to a better understanding of the effects of board reforms on financial performance and audit quality in the Iranian capital market.
