Abstract The Goods and Services Tax (GST) remains the cornerstone of India’s fiscal architecture, yet its impact on the micro, small, and medium enterprise (MSME) sector remains a subject of intense academic and economic debate. This research evaluates the efficiency of the GST Composition Scheme specifically within the diverse industrial and retail landscape of Karnataka. As of the 2025-26 fiscal year, Karnataka consistently ranks as one of the top contributors to the national GST pool, second only to Maharashtra. However, beneath this macro-success lies a significant challenge: over 6.5 lakh small traders in the state struggle with the transition from informal cash-based systems to formal, digital credit chains. This paper examines the "Efficiency Paradox": while the scheme successfully reduces the frequency of tax filings and lowers administrative overhead, it simultaneously creates a "competitive trap" for ambitious businesses. This trap is characterized by the non-availability of Input Tax Credit (ITC) and a rigid legal prohibition on inter-state trade, which effectively penalizes growth. By synthesizing high-frequency data from the March 2026 Karnataka State Budget and qualitative field surveys from the Peenya (Bengaluru) and Hubballi industrial clusters, the study concludes that while the scheme provides essential liquidity for B2C (Business-to-Consumer) retailers, it requires urgent structural reform—termed "Composition 2.0"—to support B2B (Business-to-Business) growth and national digital expansion.

Introduction The implementation of the Goods and Services Tax (GST) in July 2017 promised a "One Nation, One Tax" regime, aimed at dismantling the internal trade barriers that had historically fragmented the Indian market. For the millions of small-scale traders in Karnataka—ranging from silk weavers in Kolar to machine-tool manufacturers in Rajajinagar—the reality of this transition has been a journey of complex adaptation and digital learning. The Composition Scheme, enshrined under Section 10 of the CGST Act, was envisioned as a "safe harbor." It was designed to be a simplified, low-compliance pathway for businesses whose aggregate turnover does not exceed ₹1.5 crore (for goods) or ₹50 lakh (for service providers). In the contemporary context of 2026, Karnataka presents a unique and pressing case study for fiscal efficiency. The state’s economy is a sophisticated blend of high-tech digital services in "Silicon Valley" Bengaluru and traditional agrarian-industrial trade hubs in cities like Mangaluru, Belagavi, and Mysuru. However, the recent 2026 State Budget has sounded a fiscal alarm, revealing a projected revenue shortfall of approximately ₹16,000 crore. This deficit is largely attributed to a combination of federal devolution issues, GST rate rationalizations, and a noticeable slowdown in local consumption. This fiscal pressure has trickled down to the enforcement level. The Karnataka Commercial Taxes Department has recently deployed advanced AI-driven data matching, scrutinizing the massive volumes of UPI and bank transactions that have become the norm even for the smallest vendors. This paper seeks to evaluate whether the Composition Scheme, in its current 2026 iteration, is truly fulfilling its mandate as a facilitator of "Ease of Doing Business" or if it has inadvertently become a restrictive cage that prevents small-scale entrepreneurs from scaling their operations beyond the state's borders. 2. Objectives of the Study To provide a comprehensive, multi-dimensional evaluation of the scheme's impact, this study focuses on the following primary objectives: Regulatory Assessment (2026 Update): To analyze the current eligibility criteria, exclusionary rules, and tax rate structures as they stand in the 2026-27 financial year, including recent amendments regarding "notified goods." Financial Impact and Margin Analysis: To quantify the "cost of simplicity" by evaluating the loss of Input Tax Credit (ITC). This involves an analysis of how the inability to offset taxes paid on inputs affects final product pricing, market competitiveness, and net profit margins. Administrative Efficiency and Compliance Costs: To measure the tangible reduction in compliance hours, professional accounting fees, and software costs for composition dealers compared to their counterparts in the regular GST regime. Growth Barrier and Scalability Identification: To investigate the specific impact of the ban on inter-state sales and the restrictions on e-commerce participation. This objective focuses on whether the tax code is artificially capping the growth of Karnataka-based micro-enterprises. Socio-Technical Scrutiny: To assess the implications of AI-driven tax enforcement (like the "Namma GST" initiatives) on small traders who may lack the digital literacy to defend against automated notices. Policy Feedback and Reform Proposals: To propose evidence-based reforms that align the tax code with the reality of a digital-first, cross-border trading environment. 3. Literature Review and Theoretical Framework 3.1 The Compliance-Standardization Paradox The "compliance-standardization paradox" suggests that while uniform tax laws simplify national administration, they impose a disproportionate burden on smaller entities. Academic literature refers to this as "compliance regression." A landmark study by the Institute for Social and Economic Change (ISEC), Bengaluru (2025) demonstrated that a regular GST taxpayer in Karnataka spends nearly 4.5% of their net profit on compliance activities—software subscriptions, GST-suvidha providers, and professional auditors. For a micro-trader, this fixed cost can be the difference between survival and insolvency. The Composition Scheme attempts to solve this by moving from "Transaction-based reporting" to "Turnover-based reporting." 3.2 Supply Chain Exclusion and the "Ghosting" of B2B Markets The theoretical framework of this paper is built on the "Supply Chain Exclusion" effect. In industrial clusters like Peenya, large Original Equipment Manufacturers (OEMs) operate on thin margins and rely heavily on ITC to remain competitive. When a small component manufacturer opts for the Composition Scheme, they cannot issue a tax invoice. Consequently, the buyer cannot claim credit for the tax paid on those components. In a competitive market, this leads to the "ghosting" of composition dealers; large buyers simply refuse to onboard vendors who cannot provide the "pass-through" of tax credits, effectively cordoning off small traders into a low-value, B2C-only market segment. 4. Methodology: A Multi-Zonal Approach This research utilizes a Mixed-Methods Exploratory Design to capture both statistical trends and human narratives: Secondary Data Analysis: An exhaustive review of the GSTN Statistical Reports (2025), the Karnataka Economic Survey 2025-26, and the Mid-Year Review of State Finances. Primary Survey and Field Interviews: A structured survey of 120 traders conducted across three distinct economic zones in Karnataka: Zone A (The Tech-Industrial Hub - Bengaluru Urban): Characterized by high e-commerce potential and dense B2B manufacturing linkages. Zone B (The Border Economic Corridor - Belagavi they must pay 1% on their total turnover, including items that are otherwise exempt from GST, which often serves as a "simplicity penalty." 6. Financial Efficiency: The "Simplicity vs. Savings" Trade-off 6.1 The Liquidity Advantage: A Lifeline for Kiranas For a small Kirana (grocery) store in Jayanagar or Malleshwaram, the primary benefit of the scheme is Cash Flow Predictability. Under the regular GST regime, a trader must deposit tax by the 20th of the following month. If the trader has sold goods on credit—a common practice in local Karnataka neighborhoods—they must pay the tax out of their own pocket before the customer has paid them. The Composition Scheme’s quarterly payment cycle (via the CMP-08 form) provides a "working capital float" of nearly 60 days, which is often used to restock inventory dur
