Pakistan’s tax system has long struggled with low fiscal effort, heavy reliance on indirect taxes, narrow bases, and weak administration. These structural flaws have kept the tax‑to‑GDP ratio stagnant, fueled high deficits, and eroded efficiency. Beginning in the early 1990s, successive governments launched reform efforts – ranging from presumptive and withholding taxes to broadening sales tax and tariff restructuring – often under IMF programs. This paper reviews Pakistan’s tax reform experience during the decade, focusing on political economy constraints, governance capacity, and the factors shaping success or failure.
