The document discusses the restructuring of Pakistan's Federal Board of Revenue (FBR) and its effects on tax collection. It notes that FBR underwent major reforms between 2001-2005 with assistance from the IMF and World Bank, including restructuring FBR along functional lines, automating processes, and improving human resources. While some intermediate goals were achieved, the overall tax-to-GDP ratio target was not met and dropped to its lowest level in over 20 years by 2011. The reforms faced challenges including slow integration, underutilized IT systems, and an ineffective audit function. Further reforms are recommended such as granting FBR full autonomy and expanding the tax base.
