Reform GST, Why India Must Fix Its Distortive Input Tax Credit Chain to Become a Manufacturing Hub
India’s Goods and Services Tax (GST), launched with much fanfare in 2017 as a transformative, “one nation, one tax” reform, still struggles with a fundamental design flaw that undermines its very purpose. The recent rate rationalization, which simplified the slab structure by merging the 12% category with the 5% slab, was a welcome step. However, this simplification largely applies to supplies where Input Tax Credit (ITC) is already restricted or unavailable. In such cases, the system reverts to a cascading turnover-style taxation, fundamentally weakening the core value-added tax (VAT) principle of credit and tax neutrality. Beyond these headline-grabbing rate adjustments, deeper and more consequential structural issues remain unaddressed. The proliferation of amendments, circulars, and layered restrictions over the years has made the GST law increasingly intricate and has severely compromised the integrity of the ITC chain. Without restoring full credit neutrality, the simplification of rates alone cannot make GST function as the true, efficient, and growth-oriented VAT it was intended to be.
The Union Budget for 2026-27 presented a significant opportunity to complete this unfinished reform. Industry and tax experts alike had expected a comprehensive rationalization of the ITC framework, which remains the most distortionary feature of the current system. That opportunity was regrettably missed. The result is a continuation of the status quo, characterized by blocked working capital for businesses, avoidable tax cascades that inflate costs, and persistently high compliance costs that disproportionately burden small and medium enterprises.
A well-designed GST, in its ideal form, is a destination-based consumption tax where business-to-business transactions are entirely tax-neutral. The taxes paid on all inputs, input services, and capital goods should be fully and seamlessly creditable against the output tax liability. This ensures that the tax is levied only on the value added at each stage of the supply chain and never becomes a permanent cost burden for businesses. Preventing tax cascades across the value chain is essential for preserving the competitiveness of domestic industry in both home and export markets.
International experience across the globe consistently demonstrates that the true strength of a GST system lies far less in its rate structure and far more in the breadth of its tax base and the integrity of its credit mechanism. Countries that have minimized exclusions and built seamless, trusted credit chains achieve higher revenue productivity while simultaneously lowering compliance costs for businesses. A fragmented tax base, riddled with blocked credits and conditionalities, does the opposite: it distorts rational investment and production decisions, pushing the economy towards inefficiency.
India’s current ITC framework departs from this foundational principle in several significant and damaging ways. Multiple restrictions, complex conditionalities, and outright denials of credit have converted what should be a simple pass-through tax into a cost-imposing one. When credit is blocked, a tax cascade is created, raising the ultimate production cost. For instance, the GST paid on immovable capital goods is denied entirely to service providers and is restricted for manufacturers to only “plant and machinery.” Yet, these capital goods—office buildings, warehouses, factories—are not ‘consumed’ in the production process; they are essential assets used to conduct business operations over many years. Denying immediate credit on these investments effectively taxes investment itself, a deeply counterproductive policy for a country seeking to industrialize.
The problem is compounded by the continued exclusion of major economic sectors such as petroleum products, electricity generation and distribution, real estate, and alcohol from the GST net. The taxes paid on these critical inputs cannot be used as credits against GST liabilities and therefore become permanently embedded in the cost structure of downstream producers. Structurally, therefore, India’s GST remains an incomplete VAT. When key inputs lie entirely outside its ambit, the credit chain remains permanently patchy, and hidden taxes continue to accumulate within production. This ultimately burdens consumers with higher prices and makes domestic industry less competitive. If India aims to truly improve the ease of doing business and attract global supply chains to its shores, restoring the integrity of the GST credit chain must become the absolute centrepiece of its tax reform agenda.
The damaging consequences of this flawed design are particularly visible and acute in India’s export sector. Under the core principles of the GST framework, exports are intended to be zero-rated. This means that domestic taxes should not be embedded in the price of exported goods and services, ensuring that they can compete fairly in global markets. In practice, however, the denial of upstream credits and chronic, lengthy delays in processing refunds embed significant, unrecoverable taxes into the cost structure of exporters. When taxes paid on crucial inputs, services, or capital goods cannot be fully and timely recovered, exporters are forced to finance these amounts through additional working capital, often at high interest rates. This directly raises their costs and weakens their price edge in fiercely competitive global markets, especially in thin-margin sectors like textiles, leather goods, and light manufacturing. In an increasingly competitive global trade environment, even small cost disadvantages can lead to a significant erosion of market share.
The distortion is even worse in sectors where supplies fall under the 5% rate slab with restricted ITC. In such cases, the ITC on capital goods is either not allowed at all or is significantly curtailed. The GST, therefore, effectively acts as a tax on production, not on consumption. The tax base, in effect, shifts from consumption to investment. Firms investing in new machinery, logistics infrastructure, or advanced technology in these sectors cannot fully recover the taxes paid on their capital equipment.
The implications of this are significant and far-reaching. First, higher investment costs directly discourage capacity expansion and technological modernization in precisely the export-oriented sectors India needs to grow. Second, domestic producers operating under these truncated credit regimes may find themselves at a permanent disadvantage relative to foreign suppliers who benefit from full VAT neutrality in their home countries. This perversely encourages greater reliance on imports in certain fields, undermining the goal of self-reliance. Third, by artificially raising the cost of capital formation, such restrictions undermine long-term productivity growth and the development of globally competitive manufacturing ecosystems.
In addition to these direct costs, restrictions on credit for capital goods distort relative prices within the entire production system. Firms facing higher effective tax costs on domestic investment may delay crucial modernization or, worse, substitute locally produced goods with imported intermediates and finished goods produced under fully creditable VAT regimes abroad. Over time, such persistent asymmetries weaken domestic value addition, erode the industrial base, and significantly reduce India’s attractiveness as a preferred location for globally integrated supply chains. An inadequate and unpredictable ITC mechanism actively deters the kind of “friend shoring” by international players that India is actively courting. Restoring full and seamless creditability for all business inputs and capital goods is thus essential not only for tax neutrality, but for the very sake of India’s long-term industrial competitiveness.
We have allowed a tax system designed merely to tax consumption to distort fundamental economic decisions: where firms choose to locate their manufacturing facilities, how much they choose to invest, and whether they choose to participate in complex global supply chains. This is a policy failure that must be rectified.
If India truly aspires to become a global manufacturing hub, its GST must function as a genuine, world-class VAT. We must systematically eliminate all blocked credits that are not demonstrably related to personal consumption. We must gradually, but steadily, draw the excluded sectors into the GST base. And we must ensure time-bound, automatic refunds supported by end-to-end digitization that leaves no room for discretion or delay. Restoring credit neutrality would reduce costs, improve compliance, and dramatically strengthen export competitiveness. The next phase of GST reform, therefore, must focus single-mindedly on fixing the input tax credit chain. It is the unfinished business of India’s most ambitious tax reform.
Questions and Answers
Q1: What is the core problem with India’s GST system that the article identifies?
A1: The core problem is the compromised integrity of the Input Tax Credit (ITC) chain. Multiple restrictions, conditionalities, and outright denials of credit mean that taxes paid on inputs and capital goods cannot be fully recovered, leading to a tax cascade that raises production costs and undermines the core VAT principle of tax neutrality.
Q2: How do restrictions on ITC for capital goods harm India’s industrial competitiveness?
A2: When ITC on capital goods (like machinery or factories) is denied or restricted, GST effectively becomes a tax on investment, not consumption. This raises the cost of modernization and capacity expansion, discourages investment, and puts domestic producers at a disadvantage compared to foreign suppliers with full VAT neutrality.
Q3: Why is the export sector particularly vulnerable to the flaws in the ITC framework?
A3: Exports are supposed to be zero-rated, meaning no domestic taxes should be embedded in their price. However, when upstream credits are denied or refunds are delayed, exporters must finance these unrecoverable taxes through working capital. This raises their costs and weakens their price competitiveness in global markets, especially in thin-margin sectors.
Q4: What are the consequences of keeping major sectors like petroleum and electricity outside the GST net?
A4: The exclusion of these sectors means that taxes paid on these critical inputs cannot be credited against GST liabilities. These taxes become permanently embedded in the cost of all downstream goods and services, creating a hidden tax cascade and making the GST an “incomplete VAT.”
Q5: According to the authors, what should be the focus of the next phase of GST reform?
A5: The next phase must focus single-mindedly on restoring the integrity of the ITC chain. This includes eliminating blocked credits, gradually drawing excluded sectors into the GST base, and ensuring time-bound, automated refunds to achieve full credit neutrality, which would reduce costs, improve compliance, and boost export competitiveness.
