Abstract The implementation of GST 2. 0 reforms in September 2025 marks a transformative milestone for the Indian automobile sector. By rationalizing tax rates—reducing levies on small cars from 28% to 18% and eliminating cess on electric vehicles—the reforms have reduced vehicle prices by 10-15%, triggering record retail sales of 2. 41 million units in February 2026. This policy shift positions the automobile sector as a pivotal driver of India's economic growth, with projections of becoming a US 300 billion market by 2026. Pre-reform, the sector already contributed approximately 6% to national GDP and employed over 30 million people. Post-GST 2. 0, accelerated foreign direct investment (US 39. 15 billion), major commitments from manufacturers like Tata Motors and VinFast, and 19% export growth demonstrate renewed momentum. The reforms are catalyzing expansion of OEMs and ancillary units, with supply chain localization reaching 50% domestic content in components. The period leading to 2035 represents a golden era for Indian automobile manufacturing, with potential to generate an estimated 20 million additional jobs by 2030 and substantially enhance GDP contribution. However, realizing this potential requires addressing compliance cost burdens on SMEs, state revenue shortfalls, and ensuring equitable workforce transition. Strategic policy interventions can position India as a global hub for EV manufacturing while ensuring sustainable and inclusive growth.

GST Reforms and GST 2. 0: A Catalyst for the Automobile Sector India's Goods and Services Tax (GST), implemented in 2017, marked a significant shift from a fragmented tax structure to a unified system, reducing cascading effects and improving logistics efficiency. However, the post-pandemic economic landscape, rising input costs, and the strategic push for sustainable mobility exposed gaps in the initial framework. This led to the introduction of GST 2. 0 reforms in 2025. Announced in the 2025 Union Budget and effective from September 22, 2025, GST 2. 0 rationalizes tax rates, removes anomalies, and integrates incentives for green technology. Key changes impacting the automobile sector include: Rate Reductions: Small cars and compact SUVs saw a rate cut from 28% to 18%, while the cess on electric and hybrid vehicles was eliminated, bringing their effective rates down to 5-12%. Simplification: The reforms introduced a unified input tax credit (ITC) for auto components and removed cess on tractors and commercial vehicles. Compliance Enhancements: Digital invoicing was made mandatory for dealers, coupled with AI-driven audits to curb tax evasion. These reforms are not just a tax adjustment but a strategic catalyst. By reducing the average vehicle price by an estimated 10-15%, GST 2. 0 is poised to make the automobile sector a pivotal driver of India's future economic growth. The improved affordability is expected to stimulate demand, encouraging greater foreign direct investment (FDI) in manufacturing and R&D, and generating significant employment. This virtuous cycle will likely enhance the sector's contribution to the national GDP, solidifying its role as a cornerstone of the Indian economy. 2. Automobile Sector Overview: Pre-Reform Landscape and Dynamics Prior to GST 2. 0, the Indian automobile sector was already demonstrating resilience and robust growth. As the third-largest automobile market globally, it is a cornerstone of the economy, contributing approximately 6% to national GDP and employing over 30 million people directly and indirectly. The sector's evolution from internal combustion engines to electric propulsion aligns with national goals of achieving 30% EV penetration in private cars by 2030. The sector's performance in FY25 highlighted its strength and segmentation. Two-wheelers dominated sales, accounting for 80. 2% of the market, while passenger vehicles showed steady growth. Table 1: Automobile Sales by Segment in FY25 (Source: SIAM, IBEF Automobiles Report) Segment Units Sold (Crore) YoY Growth (%) Share (%) Two-Wheelers 2. 05 8. 5 80. 2 Three-Wheelers 0. 15 12 5. 9 Passenger Vehicles 0. 45 7 17. 6 Commercial Vehicles 0. 11 5. 2 4. 3 Total 2. 76 7 100 Table 1: This table highlights the sector's resilience, with total sales reaching 2. 76 crore units, up 7% from FY24. India also leads globally in the manufacturing of electric two-wheelers (E2W) and three-wheelers (E3W). In FY25, EV sales hit 19. 7 million units (16. 9% YoY growth), with a penetration rate of 9. 98% in Q2 FY26, largely driven by the 2W and 3W segments (91. 41% of volumes). This growth was supported by policies like the FAME II scheme, which had subsidized 16. 29 lakh EVs by June 2025, and the installation of 8, 885 charging stations. The market is projected to expand dramatically, from US 2. 36 billion in 2024 to US 164. 42 billion by 2033, at a CAGR of 57. 23%. 3. Impact of GST 2. 0 Reforms: Opportunities and Challenges The implementation of GST 2. 0 has had a multi-faceted impact on the automobile sector, creating significant opportunities while also surfacing considerable challenges. 3. 1 Opportunities Arising from GST 2. 0 Enhanced Affordability and Demand Surge: Lower tax rates have democratized access to vehicles. In February 2026, retail sales hit a record 2. 41 million units. EVs, now 7-10% cheaper, saw e-PV sales double to 13, 178 units in June 2025. This demand surge aligns with the sector's projection to become a US 300 billion market by 2026. Boost to EV Ecosystem and Exports: The reforms have made India a more attractive investment destination. FDI inflows reached US 39. 15 billion (Apr 2000-Jun 2025). Major investments, such as Tata Motors' Rs. 9, 000 crore and VinFast's Rs. 16, 000 crore facility in Tamil Nadu, exemplify the new opportunities. Consequently, automobile exports grew by 19% in FY25. Table 2: Key Investments Post-GST 2. 0 (Source: IBEF EV Report) Investor Amount (Rs.

The push for localization under schemes like FAME II is driving 50% local content in components, strengthening the domestic supply chain. 3. 2 Challenges in Implementation Supply Chain and Input Cost Pressures: Despite lower tax rates, global disruptions like semiconductor shortages and rare earth metal supply issues persist. Furthermore, small and medium enterprises (SMEs) face 20-30% higher compliance costs due to new digital mandates. Revenue Implications for States: The removal of cess may cause an annual revenue shortfall of up to Rs. 50, 000 crore for states. This could lead to uneven adoption, with some states like Bihar considering higher road taxes, potentially offsetting the benefits of GST 2. 0.

Environmental: The benefits of EVs are partially undermined by a coal-heavy grid (65% thermal), a high water footprint in battery manufacturing, and a lack of robust recycling infrastructure leading to toxic waste. Equity: EV adoption is concentrated in urban areas, exacerbating the rural-urban divide. The informal auto workforce (mechanics, drivers), comprising 86% of the sector's employment, faces job precarity without adequate retraining programs. Low-income groups also struggle to access financing for EVs due to a lack of credit history. Conclusion and Recommendations GST 2. 0 has proven to be a pivotal catalyst for the Indian automobile sector, propelling it towards greater sustainability, affordability, and market expansion. The opportunities—in terms of demand surge, investment attraction, and job creation—have the potential to outweigh the challenges, positioning the sector to play an even more critical role in India's economic future. However, realizing this potential fully requires a concerted effort to address the accompanying supply-side vulnerabilities and socio-environmental concerns. Recommendations: Expand PLI for SMEs: To offset the increased compliance costs, the Production Linked Incentive (PLI) scheme should be expanded specifically for SMEs in the auto component sector. Pilot Green Financing for States: Instead of imposing higher road taxes, states should be encouraged to pilot cess alternatives tied to green bonds to fund EV infrastructure, mitigating revenue shortfalls sustainably. Integrate Just Transition Programs: Policy must integrate skilling and retraining programs for the informal workforce, coupled with targeted financing schemes for rural and low-income groups to ensure an equitable transition. Strengthen Recycling and Grid Decarbonization: A concurrent push for battery recycling infrastructure and faster decarbonization of the electricity grid is essential to realize the full environmental benefits of EV adoption. Future research should focus on quantifying the long-term GDP and employment impacts of these reforms using robust econometric models. References IBEF. (2025). Automobiles Report, November 2025.
