Background: Reporting delinquency as an important and effective moral behavior can be influenced by the moral values that govern individuals' organization and personality traits. Therefore, given the importance of reporting in identifying and preventing organizational delinquency, it is necessary to gain a better understanding of the factors that affect it. This study aims to investigate the effect of self-control and social desirability on the ethical reporting of banking delinquency of bank employees, with emphasis on demographic characteristics. Material and Methods: This descriptive-survey study was conducted, and its sample size consisted of 306 public and private bank branch employees. The research variables were measured using standard questionnaires, and finally, structural equations, confirmatory factor analysis method, and PLS software were used to analyze the data and test the hypotheses. Results: The findings indicate that self-control and social desirability affect the ethical reporting of banking delinquency is confirmed. Social desirability also affects the relationship between self-control and honest reporting of banking delinquency. On the other hand, work experience, type of job position, and gender of employees directly impact the ethical reporting of banking delinquency. Conclusions: The study results show that people with higher self-control seek more social desirability and are more inclined to report delinquency. It also seems that bank employees, in proportion to job promotion and increasing work experience, better understand the value of reporting delinquency and, with a greater sense of commitment, try to identify and report violations to improve the bank's position. Therefore, by formulating ethical guidelines, incentive policies, and accountability, positive personality traits (self-control and social desirability) and inherent reporting motivations of bank employees can be strengthened.
