Despite the considerable harm caused by corporate crimes, this area remains relatively overlooked within the field of criminology. Anchored in an interest of enhancing initiatives targeting corporate crimes, this study investigates the nonobligatory component of anonymous reporting options in internal whistleblower schemes. Utilizing a triangulation of quantitative and qualitative methods, the study builds its findings on survey data collected on 104 respondents and interviews with selected survey respondents. The findings reveal that the option of anonymity has a significant impact on reporting intentions, particularly in scenarios involving a more severe context. Anonymity is found to be important as it diminishes employees' perceived fear associated with reporting, positively impacting the weighted cost-benefits connected to the decision-making process. These results carry implications for organizational policy and practice, emphasizing the need for proactive measures to ensure the effectiveness of internal whistleblower schemes in addressing corporate crime
