Most of the e-Government projects facing problem in integration with external services, hence there is a lack of collaboration and exchange information among different public administration e-services. Directorate General of Tax (DGT) has developed many electronic services, but until today the interoperability maturity level of that services never been assessed. Interoperability Maturity Model (IMM) is a methodology to get insight and evaluate interoperability maturity of public service based on a set of defined attribute and maturity stage. We used IMM as the methodology for interoperability maturity evaluation in this research because it is the most recent, has a complete attribute for each interoperability layer, open resources and has been used in Europe's interoperability improvement program. According to the assessment, DGT's Interoperability maturity is in level 3 for overall areas. In other words, DGT electronic services are at an essential stage. The main component of interoperability best practice has implemented in DGT's electronic services.
