GST Reforms and India's Economic Growth: An Analysis of Policy Changes and Global Comparisons (2020–2026)

Abstract The Goods and Services Tax (GST) has been one of the most significant fiscal reforms in India’s indirect tax system. Introduced in 2017, GST replaced multiple indirect taxes and created a unified national market. Since 2020, several reforms have been implemented to simplify compliance, rationalize tax rates, and enhance digital tax administration. This paper examines the evolution of GST reforms in India between 2020 and 2026 and analyses their impact on economic growth, consumption, and formalization of the economy. The study also compares India’s GST framework with similar value-added tax systems adopted in developed economies such as the United Kingdom, Australia, and Canada. The findings suggest that GST reforms have contributed to improved tax compliance, enhanced ease of doing business, and increased consumption demand, although challenges such as revenue sharing between states and tax rate complexities remain. The study concludes that continued rationalization, digital integration, and policy stability are essential for maximizing GST’s contribution to India’s long-term economic growth.

The Goods and Services Tax (GST), implemented in India on July 1, 2017, represented a major transformation of the country’s indirect tax structure. GST replaced several taxes such as value-added tax (VAT), service tax, excise duty, and entry tax with a single tax system applicable across the country. The primary objective of GST was to create a unified national market by eliminating cascading taxes and simplifying the tax structure. Over the years, the GST system has undergone continuous reforms to address implementation challenges, improve compliance mechanisms, and enhance revenue efficiency. Between 2020 and 2026, the Government of India introduced several reforms, including rate rationalization, digital compliance systems such as e-invoicing and e-way bills, simplified registration procedures, and automated refund mechanisms. These reforms were designed to improve ease of doing business and strengthen economic growth. By 2025, GST registrations had exceeded 1.6 crore and over 98% of returns were filed online, demonstrating the strong digital integration of the system. This paper analyses the evolution of GST reforms during the 2020–2026 period and evaluates their contribution to India’s economic growth while comparing the system with GST/VAT models in developed economies. 2.Concepts of GST Goods and Services Tax (GST) is a destination-based indirect tax levied on the supply of goods and services. Unlike the earlier tax system, GST eliminates cascading taxation by allowing businesses to claim input tax credit (ITC) on taxes paid on inputs. The key principles of GST include: Destination-Based Taxation GST is collected at the place where goods or services are consumed rather than where they are produced. Input Tax Credit Mechanism Businesses can claim credit for taxes paid on inputs, thereby reducing the tax burden and avoiding double taxation. Dual GST Structure India follows a dual GST system consisting of: Central GST (CGST) State GST (SGST) Integrated GST (IGST) for interstate transactions Digital Tax Administration GST operates through the GST Network (GSTN), a digital platform for registration, return filing, payment, and refund processing. These principles aim to simplify taxation, increase transparency, and improve tax compliance across the economy. 3.Objectives of the Study The present study is conducted with the following objectives: To understand the concept and structure of the Goods and Services Tax (GST) in India. To analyze the major GST reforms introduced in India during the period 2020–2026. To examine the impact of GST reforms on India’s economic growth and tax administration. To compare India’s GST system with the VAT/GST systems of selected developed countries. To identify the challenges and future prospects of GST reforms in India. 4.GST Reforms in India (2020–2026) Digitalization and Compliance Reforms One of the major developments during this period was the expansion of digital tax administration. E-invoicing became mandatory for businesses above certain turnover thresholds, enabling real-time tracking of transactions and reducing tax evasion. The e-way bill system also improved monitoring of interstate trade and logistics. In addition, automated refund systems and simplified return filing mechanisms were introduced to reduce administrative delays and improve business liquidity. Simplification of Registration and Filing The GST Council introduced faster registration processes and automated approval mechanisms. In many cases, GST registration can now be completed within three days for low-risk businesses. Furthermore, pre-filled GST returns based on invoice data are being introduced to reduce compliance burdens and improve accuracy. GST Rate Rationalization (GST 2.0) A major reform occurred in 2025 when the GST Council simplified the tax rate structure. The earlier multi-tier system of 5%, 12%, 18%, and 28% was rationalized into a simplified structure consisting mainly of 5% and 18% slabs, with a higher rate of about 40% applied to luxury and sin goods. This reform aimed to reduce tax complexity, lower consumer prices, and boost consumption. Sector-Specific Reforms Several sectors benefited from GST reforms, including: Textiles and fertilizers, where tax rates were reduced to correct inverted duty structures. E-commerce operators, where tax deducted at source (TDS) was reduced to ease compliance burdens. MSMEs, where compliance procedures were simplified and digital tools introduced. These reforms improved liquidity, reduced compliance costs, and encouraged formalization of businesses. 5.Impact of GST Reforms on India’s Economic Growth GST reforms have had significant macroeconomic implications for India’s economy. First, GST has enhanced tax compliance and formalization. Many businesses have registered under GST to claim input tax credits, bringing previously informal economic activities into the formal tax system. Second, GST reforms have improved ease of doing business by reducing interstate trade barriers and streamlining supply chains. Third, lower GST rates on consumer goods are expected to boost consumption demand. According to economic assessments, GST reforms could support India’s GDP growth, with forecasts suggesting growth around 6.9% in FY2026 partly due to consumption gains from tax reforms. Finally, digital tax systems have improved transparency and reduced tax evasion, strengthening government revenues over time. 6.Comparison of GST Systems with Developed Countries Australia Australia introduced GST in 2000 with a single tax rate of 10% applied to most goods and services. The system is relatively simple compared to India’s multi-rate structure. Canada Canada operates a dual GST/HST system where the federal government collects GST while provinces levy harmonized sales taxes. This system is similar to India’s dual GST structure. United Kingdom The United Kingdom follows a Value Added Tax (VAT) system with a standard rate of 20%, reduced rates for certain goods, and exemptions for essentials. Comparison with India Compared to developed countries: India initially adopted a multi-rate GST system to address socio-economic diversity. Developed countries typically maintain fewer tax slabs. India’s GST system is more digitalized, with mandatory electronic invoicing and real-time compliance monitoring. The recent GST reforms moving toward fewer tax slabs indicate that India is gradually aligning its system with global best practices. 7.Challenges in GST Implementation Despite significant reforms, several challenges remain: Revenue Sharing Issues: States remain concerned about revenue losses after the expiry of compensation mechanisms. Complex Tax Structure: Although simplified recently, multiple tax slabs still create compliance challenges. Input Tax Credit Restrictions: Exemptions sometimes lead to cascading taxes and distort production decisions. Compliance Burden for Small Businesses: MSMEs still face administrative challenges in filing returns and maintaining digital records. Conclusion GST reforms between 2020 and 2026 have significantly strengthened India’s indirect tax system. Digital compliance mechanisms, simplified procedures, and tax rate rationalization have improved transparency, reduced tax evasion, and enhanced ease of doing business. The transition toward a simplified GST structure is expected to increase consumption demand and support economic growth in the long run. Comparisons with developed countries reveal that while India’s GST system initially adopted a complex multi-rate structure, recent reforms are gradually aligning it with global best practices. For GST to fully realize its potential as a driver of economic growth, policymakers must continue to focus on rate rationalization, improved dispute resolution mechanisms, and enhanced support for small businesses. With sustained reforms, GST can play a crucial role in strengthening India’s fiscal capacity and supporting long-term economic development. References: Government of India. (2024).
