This document discusses corporatization and taxation issues in Pakistan's economy based on data from the Securities and Exchange Commission of Pakistan (SECP) and Federal Board of Revenue (FBR). It notes that while over 64,000 companies are registered with SECP, only around 24,000 file tax returns with FBR each year, leaving a gap of around 40,000 non-filers. It analyzes sector-wise company registration trends and financial information. Low corporatization is attributed to over-taxation, multiple taxes, and an unfriendly tax regime. Solutions proposed include improving enforcement, securitizing tax debts, and taxing non-filers and nil filers identified by FBR.
