Sistema de controlo interno no Departamento de Fiscalidade : implementação do modelo COSO no Grupo X

Abstract

Nos finais da década de noventa do século passado e inícios do século XXI, uma série de escândalos relacionados com fraudes financeiras emergiram, pondo em causa a credibilidade da informação divulgada pelas organizações. Neste contexto, foram-se desenvolvendo normas, códigos, diretrizes e modelos para ajudar as organizações no que diz respeito à gestão e ao governo das sociedades. Destes, destaca-se o modelo COSO, pela sua aceitação a nível mundial. Este estudo tem como objetivo, partindo de uma revisão de literatura sobre auditoria, controlo interno e modelo COSO, avaliar, à luz deste modelo, o sistema de controlo interno existente no departamento de fiscalidade, de um grande grupo português. Assim, a partir da observação e participação direta em atividades, reuniões, entrevistas e análise documental, procuraram-se evidências relativas à presença e funcionamento de cada uma das componentes e respetivos princípios de controlo interno, conforme definido no modelo COSO. Concluiu-se que, apesar da maior parte dos princípios estarem presentes, alguns riscos, materialmente relevantes para o departamento de fiscalidade, não tinham procedimentos de controlo associados. Também se constatou a existência de uma deficiência generalizada no que respeita à formalização da informação por escrito. Desta forma, expõe-se a análise efetuada ao sistema de controlo interno do departamento de fiscalidade e apresentam-se sugestões de melhoria.

In the late 1990’s and early 2000’s, a series of scandals related to financial fraud emerged, undermining the credibility of the information released by organizations. In this context, standards, guidelines and frameworks have been developed to help organizations in matters of corporate governance. From these, the COSO’s framework stands out for its worldwide acceptance. This study aims, through a review of the literature on auditing, internal control and the COSO’s framework, to apply this framework to the specific case of the tax department of a large Portuguese group. From the observation and direct participation in activities, meetings, interviews and documentary analysis, evidence was sought regarding the presence and functioning of each component, and respective principles of internal control. In conclusion, although most of the principles were present, some material risks had no associated controls. It was also found that there was a general deficiency in the documentation of the information. After the internal control system of the tax department analysis, based on COSO’s framework, suggestions were made.
