Specifications include, but are not limited to: The Delaware Division of Revenue (DOR) is launching a project to replace all tax processing systems with a single solution that meets the State's need for an Integrated Revenue Administration System (referred to throughout this RFP as “IRAS” or “the System”) that provides centralized revenue management, processes, and a robust web interface for its taxpayers, stakeholders, and DOR staff. All associated taxrelated functions will be converted to IRAS according to a timetable that will maximize impact and reduce taxpayer risks. DOR intends to enter into a contract with a vendor that can provide a highquality, proven system, as well as implementation and ongoing support services.
