Sales Tax Chaos & Fiscal Balkanisation Huzaima Bukhari & Dr. Ikramul Haq Pakistan practices one of the most distorted and fragmented sales tax systems in the world. What was originally introduced in 1990 as a modern value-added taxation model gradually degenerated into a maze of overlapping jurisdictions, multiple authorities, inconsistent laws, excessive rates and coercive enforcement mechanisms that now impede economic growth rather than facilitate revenue generation. The tragedy is that despite extraordinarily high statutory rates, Pakistan still fails to collect sales tax commensurate with the size of its economy. This contradiction exposes the structural failure of the existing model which empowers Federal Board of Revenue (FBR) to collect sales tax on goods while provinces are entrusted to impose and collect sales tax on services. This demarcation has created serious contentious issues of classification of goods and services, especially where contracts of goods and services are inseparable. The standard sales tax rate on goods currently stands at 18 percent at the federal level, while provincial sales tax rates on services range from 15 to 19.5 percent. However, in the case of goods, the effective incidence historically remained dramatically lower due to exemptions, leakages, informality, under-invoicing, smuggling and administrative fragmentation. The same is true for sales tax on services due to excessive input claims etc. The recent series on this topic specifically highlighted this distortion. The Tax Reforms Commission in its final report of 2016 (marked confidential by then finance minister) acknowledged that despite a nominal rate of 17 percent at the time of preparing the report, effective incidence hovered merely around 3-3.5 percent. Even after aggressive taxation measures and repeated rate increases, effective collection remains far below statutory levels because the system framework itself is defective. Pakistan has created a peculiar taxation regime where high nominal rates coexist with low effective collection. This is economically disastrous. Excessively high rates imposed upon a narrow and fragmented base encourage concealment, under-reporting and informal transactions. Businesses respond rationally by shifting activity outside documented channels wherever possible. Smuggling becomes more profitable. Compliance costs rise. Consumers face inflationary burdens while revenues still underperform. The state then responds with even harsher enforcement and additional rates, deepening the cycle further. This is precisely what happened in Pakistan. The constitutional restructuring following the Constitution (Eighteenth Amendment) Act, 2010 [18th Amendment] complicated matters further. Sales tax on services shifted to provinces while sales tax on goods remained with the federation. In principle, fiscal decentralisation could have strengthened federalism and improved accountability. In practice, however, Pakistan developed one of the most fragmented indirect taxation systems in the region. Multiple provincial revenue authorities emerged, each operating separate registration systems, procedures, audit mechanisms and legal interpretations. Businesses operating nationally suddenly found themselves trapped in overlapping compliance regimes. A single enterprise providing services across provinces may today confront multiple sales tax authorities simultaneously, each demanding separate registration, separate returns, separate audits and sometimes contradictory interpretations of the same transaction. This is not fiscal federalism. It is fiscal balkanization and its economic costs are enormous. Compliance expenses for businesses increased sharply. Smaller enterprises struggle to navigate fragmented procedures. Litigation multiplied because jurisdictions overlap constantly. Digital and trans-provincial services created further constitutional confusion regarding situs, territorial nexus and taxing authority. The irony is painful. At the very moment when the global economy is moving toward integrated digital taxation systems, Pakistan has unwisely fragmented its indirect taxation structure into competing bureaucratic silos. The consequences extend beyond administrative inconvenience. Fragmented sales taxation weakens documentation itself. Businesses increasingly prefer informal transactions to avoid multiplicity of compliance. Inter-provincial economic integration suffers. National supply chains become vulnerable to inconsistent taxation policies and enforcement practices. This undermines competitiveness, exports and investment simultaneously. The present model also encourages excessive dependence upon import-stage taxation. A substantial portion of sales tax on goods is effectively collected at import stage rather than through a genuinely functioning value-added chain. While this provides short-term revenue certainty, it weakens domestic documentation incentives and shifts disproportionate burden onto organised and import-dependent sectors. The distortion becomes even more severe when combined with customs duties, advance taxes and withholding provisions imposed simultaneously at import stage. The result is cascading taxation embedded throughout the production process. Pakistan's exporters repeatedly complained about blocked refunds, delayed input adjustments and liquidity constraints arising from this defective structure. Working capital gets trapped within the taxation machinery while businesses continue facing high financing costs and energy burdens. The system thus taxes production before profitability itself materialises. Retail and wholesale sectors expose another dimension of this failure. Despite repeated point-of-sale schemes and retailer documentation campaigns, large segments of internal trade remain outside effective sales tax coverage. Successive governments announced "historic" retailer integration drives, yet most initiatives collapsed due to political resistance, excessive compliance burdens and lack of trust between traders and the state. The experience demonstrated a simple reality: documentation through coercion alone cannot succeed. Comparative international experience offers important lessons. Bangladesh recently moved toward source-based taxation models targeting retailers through upstream transaction monitoring and integrated supply-chain documentation rather than fragmented harassment-based approaches. Other federations similarly rely increasingly upon harmonised digital invoicing systems and coordinated tax administration instead of overlapping bureaucratic structures. Pakistan unfortunately continues moving in the opposite direction. Instead of harmonisation, complexity has expanded and procedural burdens have multiplied. The fragmentation has deepened to an alarming level. This structural disorder also raises serious constitutional questions. Articles 141 and 142 of the Constitution define legislative competence between federation and provinces. However, many recent taxation disputes reveal increasing jurisdictional overlap and attempts at extra-territorial taxation by provincial authorities. Businesses operating digitally or across provincial boundaries often face uncertainty regarding actual tax liability and situs rules. This uncertainty itself discourages investment and formalisation. A modern economy cannot function efficiently where indirect taxation resembles competing toll barriers within the same federation. Pakistan therefore urgently requires comprehensive sales tax reform grounded in economic rationality and constitutional coherence. First, sales tax rates must gradually decline while the base expands genuinely. Lower and predictable rates encourage compliance far more effectively than punitive nominal taxation. Second, federal and provincial sales tax systems must be harmonised administratively through integrated registration, unified return systems and interoperable databases. Third, digital invoicing and real-time transaction documentation should replace discretionary enforcement and harassment-based approaches. Fourth, import-stage dependence must gradually shift toward proper domestic value-added documentation. Fifth, refunds and input adjustments should become fully automated and time-bound to prevent liquidity destruction within productive sectors. Sixth, trans-provincial and digital services require constitutionally coherent taxation rules preventing overlapping jurisdictional claims. Most importantly, indirect taxation must stop functioning as a substitute for failure to tax wealth and income properly. Pakistan overburdened consumption because politically powerful sectors escaped meaningful direct taxation. This imbalance intensified inflationary pressures, widened inequality and weakened purchasing power. A sustainable fiscal system cannot rely indefinitely upon taxing consumption while protecting accumulated wealth. The future lies in a broad-based, low-rate and harmonised taxation structure integrated with a modern federalised tax administration. Without such restructuring, every future increase in sales tax rates will merely intensify inflation, encourage informality and weaken competitiveness while still failing to produce sustainable revenues. Pakistan's present sales tax structure no longer reflects fiscal federalism. It reflects administrative fragmentation masquerading as decentralisation. Unless this chaos is addressed seriously, the country will continue experiencing the same paradox: higher rates, lower compliance and shrinking economic vitality beneath rising nominal revenue claims. _____________________________________________ Huzaima Bukhari, lawyer and author, is an Adjunct Faculty at Lahore University of Management Sciences (LUMS), member Advisory Board and Senior Visiting Fellow of Pakistan Institute of Development Economics (PIDE) Dr. Ikramul Haq, Advocate Supreme Court, Adjunct Faculty at Lahore University of Management Sciences (LUMS), member Advisory Board and Visiting Senior Fellow of Pakistan Institute of Development Economics (PIDE), holds LLD in tax laws.
