This paper reports on work in progress. We present a methodology for constructing an OWL-DL model of a subset of Danish VAT rules. It is our intention that domain experts without training in formal modeling or computer science should be able to create and maintain the model using our methodology. In an ERP setting such a model could reduce the Total Cost of Ownership (TCO) and increase the quality of the system. We have selected OWL-DL because we believe that description logic is suited for modeling VAT rules due to the decidability of important inference problems that are key to the way we plan to use the model and because OWL-DL is relatively intuitive to use.
