The Broken Promise, How India’s GST Lost Its Way and Became a Tax on Production
The introduction of the Goods and Services Tax (GST) in July 2017 was heralded as India’s most significant economic reform since liberalization in 1991. It was envisioned as a grand unifying force, a “one nation, one tax” system that would dismantle the complex web of state and central levies, eliminate cascading taxes, and forge a seamless national market. Conceived as a modern value-added tax (VAT), its promise was to be a clean, efficient tax on final consumption, neutral to production methods and trade. However, nearly a decade into its implementation, a disquieting reality has set in. As argued by economists Ajay Shah, Vijay Kelkar, and Arbind Modi, the system has strayed far from its founding principles. Today’s GST, they contend, has become an example of “isomorphic mimicry”—it wears the skin of a modern tax to gain legitimacy, but its internal machinery is broken. The engine of the GST, the Input Tax Credit (ITC), has been systematically obstructed, transforming what was meant to be a tax on consumption back into a tax on production, reminiscent of the very system it was designed to replace.
The Core Principle: Why ITC is the Heart of a True GST
To understand the gravity of the current failure, one must first appreciate the elegant simplicity of a well-designed VAT or GST. Its entire economic logic rests on the mechanism of Input Tax Credit. The concept is straightforward: at every stage of the production and distribution chain, a business pays tax on its purchases (inputs) and collects tax on its sales (outputs). When it files its return, it deducts the tax it has already paid on its inputs from the tax it has collected on its outputs and remits only the difference—the tax on the value it has added—to the government.
This mechanism is transformative. It eliminates “tax-on-tax” or cascading, where a product is taxed at every stage without credit for taxes paid earlier. It ensures that the final burden falls only on the end consumer. Most importantly, it makes the tax neutral; it does not distort business decisions about whether to make or buy components, how vertically integrated to be, or what technology to use. The ITC system automatically creates a trail of verified transactions, reducing evasion and creating a unified market by making interstate trade as seamless as intrastate trade. Without a seamless ITC, the entire edifice of GST collapses into a complex, multi-layered sales tax.
The Great Unraveling: How ITC is Being Systematically Obstructed
The central argument against the current Indian GST model is that this vital ITC mechanism has been crippled by a series of legal and procedural blockages. The system is no longer a smooth, self-policing chain but a clogged artery, causing the tax to embed itself as a cost within the business system.
One of the most significant obstructions is the treatment of refunds under an “inverted duty structure.” This situation arises when the tax rate on inputs is higher than the tax rate on the final output. For example, a manufacturer might pay 18% GST on raw materials but sell the finished product at a 5% rate. In a pure GST system, the accumulated excess input credit should be refunded to the business in cash, ensuring it does not bear a tax cost. This is standard practice for exports, which are “zero-rated” (a 0% tax) and receive full refunds on all input taxes.
However, under Rule 89(5) of the Central GST Rules, these refunds are heavily restricted. A business can only claim a refund of the tax paid on input goods; the ITC accumulated on input services (like legal fees, logistics, accounting) and capital goods (machinery, equipment) is not refundable. This accumulated credit becomes a frozen asset, trapped on the company’s books, inflating its costs and working capital requirements.
The consequences of this blockage are not merely theoretical; they are quantifiable and severe. The divergence between the nominal GST rate and the effective tax burden reveals the extent of the damage. Consider a business operating in the 5% tax slab. Due to blocked ITC on services and capital goods, its effective tax incidence can skyrocket. The authors point out that a supplier of goods might face an effective rate of 14%, while a service provider’s burden can balloon to an astonishing 28.4%. In this form, the GST is not a modern consumption tax; it is a regressive, old-style tax on production that punishes businesses for simply operating.
The Cascading Damage: Sectoral Bias, Anti-Export Policies, and the MSME Crisis
The failure of the ITC system inflicts broad, systemic damage across the economy, with a particularly harsh impact on specific sectors and business sizes.
1. The Services Sector Disadvantage: The flawed refund rule disproportionately penalizes the services sector. A manufacturing firm can at least claim refunds on its raw materials, though it still suffers from blocked credits on services and capital goods. In contrast, a software development firm, a logistics company, or a consultancy—whose primary inputs are other services and capital equipment—receives almost no relief. Their costs remain permanently elevated by the unrefunded taxes, stifling growth in the very sectors that are engines of job creation and modern economic development.
2. The Bias in Favor of Imports: A broken credit chain creates a perverse incentive to import rather than produce domestically. A domestically manufactured product may have a nominal GST of 5%, but its final price is inflated by the uncredited taxes embedded in its supply chain, pushing the effective burden to 14% or higher. An imported equivalent, however, is taxed at the border at the clean, nominal rate of 5%. This puts Indian manufacturers at a structural disadvantage in their own market, undermining the “Make in India” initiative and harming domestic industry.
3. A Tax on Investment: GST has inadvertently become a tax on capital expenditure. The credit for GST paid on expensive machinery and plant equipment is often deferred until the project is operational and generates its own tax liability. From a financial perspective, a credit of ₹100 today is far more valuable than a credit of ₹100 three years from now. This delay increases the real cost of capital, discouraging investment in new capacity and technological upgrades, which are crucial for long-term economic growth.
4. Hampering Export Competitiveness: While exports are theoretically zero-rated, the refusal to refund ITC on capital goods means that Indian exporters are not fully neutralized for the taxes embedded in their products. International best practice is to ensure that exports are entirely free of domestic taxes, making them competitive in global markets. By failing to do so, India’s GST rules effectively tax foreign buyers and hamper the ability of Indian companies to compete on the world stage.
5. The Crushing Blow to MSMEs: Perhaps the most socially and economically damaging impact is on Micro, Small, and Medium Enterprises (MSMEs). Large corporations have the financial resilience, legal teams, and supply chain leverage to navigate the complex refund processes, restructure operations, or absorb the cash-flow hits. MSMEs, which operate on thin margins and have limited access to credit, lack such buffers. The blocked ITC directly erodes their already slim profits, cripples their cash flow, and makes it impossible to compete with larger domestic firms or cheaper imports. The tax system, therefore, actively penalizes the most vulnerable and numerous segment of Indian business.
The Path to Redemption: A Three-Pronged Reform Agenda for GST 2.0
The authors argue that the traditional reform agenda—focusing on a single tax rate and better treatment for imports and exports—is no longer sufficient. A third, more fundamental priority must be added: the restoration of a pure ITC mechanism.
The path forward requires a decisive three-pronged approach:
-
Legislative Repair for Seamless ITC: The law must be amended to guarantee immediate, full, and flow-based ITC across all inputs—goods, services, and capital goods, without exception. This is the non-negotiable first step to restoring the GST’s economic logic.
-
Rate Rationalization Post-Repair: Only after the ITC chain is fixed should the government pursue rate simplification. The current multi-tier structure (5%, 12%, 18%) creates complexity and inversion. Once a clean ITC is in place, the lower rates can be merged upwards into a single, revenue-neutral rate in the range of 12-14%. This would simplify compliance dramatically while maintaining revenue.
-
Administrative Overhaul through Technology: The refund process must be made swift and trust-based. The authors propose a GST Central Processing Centre (GST-CPC), modelled on the successful Income-Tax CPC, which would automate return processing and issue refunds based on risk-based algorithms rather than manual scrutiny, eliminating a major pain point for businesses.
Conclusion: Reclaiming the Soul of the Reform
The Goods and Services Tax was meant to be a transformative reform that unshackled the Indian economy. Instead, it has become a source of frustration and a drag on competitiveness for many. The divergence from its core principle has turned it into a complex, cascading tax that harms domestic production, discourages investment, and unfairly targets MSMEs and the services sector. The promise of a “one nation, one market” remains unfulfilled.
Reforming the GST is not about tinkering with tax slabs; it is about a philosophical return to first principles. It is about recognizing that the soul of an indirect tax is its neutrality and its focus on final consumption. By fixing the broken engine of Input Tax Credit, India can still reclaim the promise of its most ambitious tax reform and build a tax system that truly fuels, rather than hinders, its economic ascent.
Q&A Section
Q1: What is “isomorphic mimicry” in the context of India’s GST?
A1: “Isomorphic mimicry” is a term used to describe a situation where a system adopts the external form of a successful model to gain legitimacy but fails to replicate its core functional principles. In the case of India’s GST, the system has the name and appearance of a modern value-added tax (VAT), but its internal machinery—specifically the crippled Input Tax Credit (ITC) mechanism—does not function as it should. It looks like a GST from the outside but behaves like an old, inefficient production tax on the inside.
Q2: How does the “inverted duty structure” and its related refund rules harm businesses?
A2: An inverted duty structure occurs when the tax rate on inputs is higher than the tax rate on the final output. The GST rules restrict refunds for this situation, allowing businesses to only claim back taxes paid on input goods, but not on input services or capital goods. This means a portion of the tax they pay becomes a permanent cost, inflating their expenses and trapping their working capital. This leads to an effective tax rate that can be much higher than the nominal rate, hurting profitability and competitiveness.
Q3: Why does the current GST system create a bias in favor of imports over domestic production?
A3: The current system creates an import bias because a domestically produced item carries an embedded tax burden from blocked ITCs throughout its supply chain. So, a product with a 5% nominal GST might have an effective tax cost of 14%. However, an imported equivalent is taxed at the border at the clean, nominal rate of 5%. This makes the imported product cheaper, putting domestic manufacturers at a significant disadvantage in their own market.
Q4: How are Micro, Small, and Medium Enterprises (MSMEs) disproportionately affected by the flaws in GST?
A4: MSMEs are disproportionately affected because they lack the financial resilience of large corporations. The blocked ITC directly hits their cash flow and erodes their thin profit margins. They do not have the legal resources to navigate complex refund processes, the credit lines to absorb the financial hit, or the supply chain power to restructure their operations. This makes it incredibly difficult for them to compete, stifling growth and survival in a critical segment of the economy.
Q5: What is the first and most critical step proposed by the authors to fix the GST system?
A5: The authors argue that the first and most critical step is a legislative amendment to guarantee a seamless, full, and immediate Input Tax Credit (ITC) for all business inputs—goods, services, and capital goods alike. This is the foundational repair needed to restore the GST’s core principle of being a tax only on final consumption. Without fixing this broken engine, any other reforms, such as rate rationalization, will be built on a flawed foundation.
