Abstract

In recent years, compliance management has gained more and more interest from a practice and research point of view. The financial service industry, in general, is strongly regulated and has to follow specific laws, standards and guidelines. However, research has shown that little attention is being paid to Value Added Tax (VAT) issues, although there is a high cost and risk exposure, especially in large international companies which use large IT-Infrastructures for tax handling. In this paper, we examine a commonly applied approach for the verification of VAT regulations within Enterprise Resource Planning systems (ERP) and highlight weaknesses as well as error susceptibilities. Furthermore, we show that machine learning techniques can be utilized to minimize risks and increase VAT compliance. We use a supervised learning classifier to predict tax subjects and corresponding tax rates based on related voucher information of journal reports. By comparing the results of our model with the existing rule-based system which in included in the ERP system we reveal potential anomalies and compliance issues. Our approach was evaluated on the given real-world data set of a leading chemical industry company based on export of the ERP system. The results were validated by VAT experts of the company.
