GST Reforms and its Influence on GDP Growth, Inflation and Fiscal Federalism in India

Abstract The introduction of the Goods and Services Tax (GST) in India in July 2017 marked one of the most significant tax reforms in the country’s fiscal history. By replacing multiple indirect taxes such as excise duty, service tax, and value added tax (VAT), GST aimed to create a unified national market, improve tax compliance, and strengthen economic efficiency. This study examines the influence of GST reforms on three key macroeconomic indicators—Gross Domestic Product (GDP) growth, inflation, and fiscal federalism. The research integrates both primary and secondary data sources to analyse the economic implications of GST since its implementation. Secondary data were collected from government reports, RBI publications, GST Council documents, and academic studies, while primary data were gathered through a survey of 150 respondents including tax professionals, business owners, and economists. Statistical analysis and descriptive techniques were used to interpret the results. The findings indicate that GST reforms have contributed positively to economic growth by reducing cascading taxes, improving logistics efficiency, and enhancing tax compliance. Empirical studies suggest that increases in GST revenue have a significant positive relationship with GDP growth, with one percent growth in GST revenue contributing to approximately 0.56 percent growth in GDP. The study also reveals that while GST initially created mild inflationary pressures due to tax restructuring and compliance adjustments, its long-term impact has moderated price levels by eliminating multiple taxation and improving supply chain efficiency. Additionally, GST has transformed India’s fiscal federal structure through cooperative federalism, with the GST Council acting as a key platform for coordination between the central and state governments. The research concludes that although GST reforms have strengthened economic integration, further policy refinements are necessary to enhance revenue stability and state autonomy. Keywords: GST reforms, GDP growth, inflation, fiscal federalism, indirect taxation, economic reforms 1. Introduction: Tax reforms play a crucial role in shaping a nation’s economic structure and fiscal stability. India’s Goods and Services Tax (GST), introduced on 1 July 2017, replaced a complex system of indirect taxes levied by both the central and state governments. The reform aimed to simplify the taxation structure, reduce cascading taxes, and create a unified domestic market. GST represents a destination-based consumption tax that integrates various indirect taxes into a single framework. By allowing input tax credits across the supply chain, GST reduces the burden of double taxation and improves efficiency in production and distribution. This reform has significant implications for macroeconomic indicators such as economic growth, price stability, and intergovernmental fiscal relations. Economic studies suggest that GST reforms can stimulate economic activity by improving logistics efficiency, encouraging formalization of businesses, and increasing government revenue through better compliance. These structural improvements contribute to long-term economic growth and competitiveness. However, the implementation of GST also created transitional challenges including compliance costs, technological adaptation, and adjustments in tax rates. These factors initially affected price levels and business operations. Moreover, GST significantly altered the fiscal relationship between the central and state governments by introducing a shared tax administration system through the GST Council. Therefore, analysing the broader economic effects of GST reforms is essential for understanding their contribution to India’s economic development and fiscal governance. 2.Need for the Study: The introduction of GST transformed India’s indirect tax system and significantly influenced macroeconomic variables. Understanding its impact is essential for policymakers and economists for several reasons: The need for the study of the Goods and Services Tax (GST) in India arises from its significant role in transforming the country’s indirect tax system and its impact on the overall economy. Introduced in 2017, GST replaced multiple indirect taxes such as VAT, service tax, excise duty, and entry tax, thereby creating a unified national market. Studying GST is important to understand how it has improved tax transparency, reduced cascading effects of taxation, and simplified the tax structure for businesses and consumers. It also helps evaluate its influence on economic growth, government revenue, inflation, and cooperative federalism between the central and state governments. Furthermore, analyzing GST provides insights into its implementation challenges, compliance issues, and the effectiveness of policy reforms in strengthening India’s fiscal system and promoting ease of doing business. GST aims to increase economic efficiency and stimulate GDP growth by creating a unified market. The reform may influence price levels and inflation due to changes in tax rates and supply chain costs. GST has reshaped India’s fiscal federal structure by altering revenue distribution between the centre and states. There is a need to evaluate whether GST has achieved its intended objectives of simplifying taxation and improving compliance. Empirical research is necessary to assess the macroeconomic outcomes of GST reforms. 3.Objectives of the Study To examine the impact of GST reforms on GDP growth in India. To analyse the influence of GST on inflation and price stability. To evaluate the role of GST in shaping fiscal federalism in India. To study the perceptions of stakeholders regarding GST reforms. To suggest policy recommendations for improving GST implementation. 4.Review of Literature Garg, S., Narwal, K. P., & Kumar, S. (2023) in their paper “Economic Impact of GST Reforms on the Indian Economy: An Empirical Analysis” examined the macroeconomic effects of GST using empirical data and concluded that GST has positively contributed to economic growth by improving tax efficiency and revenue generation. However, the study mainly focused on aggregate economic indicators and did not extensively analyze regional disparities among states or the long-term effects on fiscal federalism. Joseph, K. J. (2023) in the article “India’s GST Paradigm and the Trajectory of Fiscal Federalism” examined how GST has transformed fiscal relations between the central and state governments and highlighted issues related to revenue sharing, tax autonomy, and the functioning of the GST Council. The research gap identified is the limited empirical assessment of how these institutional changes affect state-level fiscal capacity and economic development. Krishna, S., & Shacheendran, V. (2024) in the study “Impact of Goods and Services Tax on the Economic Growth of India” used regression analysis to explore the relationship between GST revenue and GDP growth and found that GST revenue growth significantly influences economic growth in India. The research gap lies in the limited timeframe of analysis and the lack of consideration of inflation dynamics and institutional factors influencing tax reforms. Bhattacharya, R. (2024) in the paper “How Did Transition to the GST Regime Affect Inflation in India?” investigated the relationship between GST implementation and inflation using econometric methods and found that GST had some positive impact on headline inflation, particularly through retail food prices. However, the study focused primarily on inflation trends and did not explore broader macroeconomic outcomes such as GDP growth or fiscal federal relations. 5.Methodology and Research Design: The study adopts a descriptive and analytical research design. Data Sources: Secondary data were obtained from: Secondary Data: Reserve Bank of India (RBI) – RBI Bulletin and Annual Reports, Ministry of Finance, Government of India – Economic Survey of India, Goods and Services Tax Council Reports and GST Portal Data, IMF Article International Monetary Fund (IMF) Article IV Consultation Reports on India, Reports from the GST Council provide information on GST policy reforms, World Bank Reports on Tax Reforms and Economic Growth, Academic Journals (Elsevier, Springer, Taylor & Francis, and Indian Economic Journals)Peer-reviewed articles examine the relationship between GST revenue, GDP growth, and inflation using econometric models and time-series data. Primary Data: Primary data were collected through a structured questionnaire from 150 respondents, including: Table: 1 Respondents: Category Number of Respondents Business owners 60 Tax professionals 40 Economists 20 Consumers 30 Total 150 The table presents the distribution of respondents based on their professional categories in the study. Out of a total of 150 respondents, the largest group consists of business owners (60 respondents), as they are directly affected by taxation policies and economic reforms. Tax professionals account for 40 respondents, providing expert insights into tax compliance, implementation, and the functioning of the tax system. The study also includes 20 economists, whose responses contribute analytical perspectives on economic growth and policy impacts. In addition, 30 consumers were surveyed to understand the indirect effects of taxation on purchasing behaviour and market demand. This diverse distribution of respondents ensures that the study captures multiple viewpoints from key stakeholders, thereby enhancing the reliability and comprehensiveness of the research findings. 6.Results, Discussion and Data Analysis Before the implementation of the Goods and Services Tax, India maintained moderate economic growth, with GDP growth rates averaging around 7–8% between 2014 and 2016, supported by domestic consumption a
