Many of the information systems in use at the Pennsylvania Department of Revenue (PaDOR) have been in existence for over 20 years and were implemented to address specific tax types processed by the Department. As a result, the systems exist within their own ―stovepipes‖ and present challenges to the IT and business support teams when attempting to view and process taxpayers holistically. With the current demands that all sectors of government ―do more with less‖ the trend in tax processing is toward enterprise systems that collaboratively share information and leverage content across tax types and functions. The PaDOR has determined that it is in the best interests of the Commonwealth to leverage the investments made in the SAP technology platform and to implement an integrated tax solution based on the SAP Tax and Revenue Management solution. Additional detail is provided in Part IV of this RFP.
