This paper investigates the connection of internal control environment to sustainable development goals to curb fraud in Brazil. We drew on the interpretivist and constructivist perspectives with discourse analysis. Data corpus consists of interviews of 20 respondents who are external auditors, internal auditors, and employees of the controller’s department of an organization of ecommerce and archival documents. Results did not find any significant relationship between the connection of internal control functions (ICF) and the Sustainable Development Goals (SDGs) inasmuch as the connection of ICF to efficiency is tied to policies in compliance with standards, management tone, roles of enforcement, accountability, and adherence and obedience of rules. Triangulating SDG-16 with the dimensions of the control environment, fraud manifests mainly as a result of lack of commitment to integrity and values, as well as ineffectiveness of monitoring functions. This study concludes for the building of effective, accountable and even institutions with the embedding monitoring functions to sustain development goals. Since ex ante literatures examined the conceptual framework in isolation, this study connects it to sustainable development goals. Finally, this study signals an implication in the internal control literature as it clarifies the scientific theories and practical baseline of internal control environment to the policymakers, practitioners, and academia in view of the way forward on the connection of ICF to the SDG in the fight against corporate frauds.
