A Study on the Impact of GST in Reshaping the Indian Economy

Abstract

The Goods and Services Tax (GST), implemented in India in July 2017, is a landmark reform in the country’s indirect taxation system. This study examines GST’s impact on economic growth, tax compliance, formalization, and sectoral performance using secondary data from government reports, GST Council updates, and research articles. Findings indicate that GST has increased revenue collection, improved transparency, and enhanced supply chain efficiency. However, MSMEs face compliance challenges, and the GST-to-GDP ratio still has room for improvement. Recommendations include simplifying the tax structure, strengthening digital infrastructure, supporting MSMEs, and ensuring timely refunds to maximize GST’s long-term benefits.

Keywords: GST, Indian Economy, Economic Growth, Tax Compliance, Formalization, Supply Chain Efficiency

1. Introduction

Before GST, India had multiple indirect taxes such as VAT, excise duty, and service tax, which created a cascading tax effect and increased costs. GST, launched on 1st July 2017, introduced a destination-based tax system for goods and services with the principle of “One Nation, One Tax.” The reform aimed to simplify taxation, reduce costs, integrate markets, and formalize the economy. The GST system includes multiple tax slabs, input tax credit (ITC) mechanisms, and digital filing, all designed to improve compliance and transparency.

2. Objectives Of The Study

1. To analyze the impact of GST on India’s economic growth.

2. To examine the role of GST in improving tax compliance and formalization.

3. To assess the overall effectiveness of GST in reshaping the Indian economy.

3. Hypotheses

• H1: GST has positively contributed to India’s economic growth.

• H2: GST has significantly improved tax compliance and formalization.

• H3: GST has been effective in reshaping the Indian economy.

4 Review of Literature 

A number of researchers have examined the impact of Goods and Services Tax (GST) on India’s economy from different perspectives such as economic growth, tax compliance, sectoral performance, and formalization. The following review summarizes key studies relevant to this research.

Kaur and Kaur (2019)

Kaur and Kaur (2019) analyzed the impact of GST on the Indian economy and concluded that GST has significantly simplified the indirect taxation system by eliminating multiple taxes and reducing the cascading effect. The study found that GST has contributed to increased transparency and improved compliance among businesses. However, the authors highlighted that the success of GST depends on effective implementation and awareness among taxpayers. They also emphasized the need for better digital infrastructure to support small businesses.

Sinha (2020)

Sinha (2020) focused on the implications of GST for Micro, Small, and Medium Enterprises (MSMEs). The study revealed that while GST provides benefits such as Input Tax Credit (ITC) and access to a broader market, it also creates challenges due to complex compliance requirements. Many MSMEs face difficulties in adapting to digital systems and filing returns. The study recommended simplified procedures and government support to enhance MSME participation in the GST framework.

Gupta and Sharma (2021)

Gupta and Sharma (2021) examined GST as a tool for improving economic efficiency. Their study found that GST has positively impacted revenue collection and reduced logistics costs by eliminating interstate barriers. The research highlighted that sectors such as manufacturing and FMCG have experienced cost savings and improved operational efficiency. The authors concluded that GST has strengthened the supply chain and contributed to the integration of the Indian market.

Narayan (2022)

Narayan (2022) evaluated the performance of GST using the GST-to-GDP ratio as an indicator. The study observed a steady increase in the ratio from the initial years of implementation, indicating improved tax efficiency and compliance. However, the study also pointed out that India’s GST-to-GDP ratio remains lower compared to some developed economies, suggesting the need to expand the tax base and include more informal businesses under GST.

Singh and Verma (2023)

Singh and Verma (2023) conducted a sectoral analysis of GST’s impact on various industries. The study found that manufacturing, logistics, and service sectors have benefited significantly due to reduced tax burdens and improved efficiency. However, sectors such as real estate and MSMEs continue to face challenges related to compliance complexity and digital infrastructure. The authors recommended simplifying tax slabs and improving GST portal efficiency to enhance overall effectiveness.

Overall Interpretation of Literature

The literature review indicates that GST has had a positive impact on India’s economy by improving tax compliance, enhancing transparency, and promoting economic efficiency. Most studies agree that GST has contributed to the formalization of businesses and integration of markets. However, challenges such as compliance complexity, digital barriers, and sectoral disparities persist, particularly for MSMEs and small businesses.

5. Research Methodology

This study uses secondary research based on government reports, economic surveys, GST Council publications, RBI data, and research articles.

• Data Analysis: Comparative analysis (pre- vs post-GST), trend analysis of GST revenue, sectoral analysis (Manufacturing, MSMEs, FMCG, Logistics, Automobile, Real Estate, Services).

6. DATA ANALYSIS & INTERPRETATION

6.1 GST Revenue Growth (₹ Lakh Crore)

Interpretation: Revenue nearly doubled over 7 years. COVID-19 caused a temporary dip, but recovery was strong.

6.2 GST-to-GDP Ratio (%)

Interpretation: Improved revenue efficiency, but scope remains to formalize more informal businesses.

6.3 Taxpayer Base Expansion

Interpretation: Strong formalization and increased compliance among MSMEs

6.4 Sectoral Impact Analysis 

7. Findings (Expanded)

1. Revenue Growth

GST collections have nearly doubled from ₹6.45 lakh crore in FY 2017–18 to ₹22.08 lakh crore in FY 2024–25. This reflects improved compliance, increased consumer demand, and effective monitoring by the GST Council. Monthly collections consistently exceeding ₹1.8–2 lakh crore indicate stable revenue streams for the government.

Example: During FY 2022–23, GST collections rose by 31.9%, showing strong post-pandemic economic recovery and higher consumption across sectors like FMCG and automobiles.

2. Formalization of Businesses

The number of registered taxpayers increased from 0.65 crore in 2017 to 1.5 crore in 2024, highlighting a trend toward formalization. GST’s digital filing system, along with Input Tax Credit (ITC), encourages businesses to operate within the legal framework. This reduces tax evasion and integrates more companies into the formal economy.

Example: Small textile units in Gujarat and food processing firms in Maharashtra now regularly file GST returns and claim ITC, allowing them access to government schemes and larger supply chains.

3. Contribution to Economic Growth

By removing cascading taxes, GST reduces production costs and increases competitiveness. Lower tax-induced costs translate into higher investment and consumer spending, driving GDP growth.

Example: The automobile sector benefited from lower taxes on inputs like steel and engines, reducing vehicle prices by 2–3%, which stimulated sales and production, contributing positively to GDP.

4. Supply Chain Efficiency

GST eliminated interstate checkposts and harmonized tax rates, reducing transportation delays and logistical costs by 10–15%. This has a direct impact on sectors like FMCG, manufacturing, and e-commerce, where timely delivery is critical.

Example: A truck carrying goods from Delhi to Bengaluru now completes delivery faster due to reduced border inspections, saving time and fuel costs.

5. MSME Challenges

While GST allows MSMEs to claim ITC and access national markets, many small businesses face compliance challenges due to complex digital filing, multiple returns, and lack of IT knowledge. This can strain working capital and operational efficiency.

Example: A small handicraft exporter in Rajasthan benefits from ITC but often delays GST filing due to unfamiliarity with e-way bills and digital returns, leading to penalties.

6. GST-to-GDP Ratio

 GST-to-GDP ratio increased from 3.48% in 2017–18 to 7.6% in 2023–24. This shows better revenue efficiency and formalization. However, states with large informal sectors still lag, indicating the need to expand GST coverage and encourage unregistered businesses to join the tax net.

Example: States like Bihar and Uttar Pradesh have high informal economies, contributing less to GST relative to GDP compared to states like Maharashtra and Gujarat.

8. Suggestions 

1. Simplify Tax Structure

Currently, GST has five tax slabs (0%, 5%, 12%, 18%, 28%), which often lead to confusion, disputes, and litigation. Simplifying the structure to 3–4 slabs can reduce compliance errors, improve understanding for MSMEs, and lower administrative costs.

Example: Consolidating slabs for similar goods, such as merging 12% and 18% into a single 15% slab, can reduce disputes in FMCG and manufacturing sectors.

2. Strengthen Digital Infrastructure

The GST Network (GSTN) is critical for filing returns, claiming ITC, and tracking transactions. Frequent downtime, slow processing, and complex interfaces pose challenges, particularly for small businesses. Upgrading servers, simplifying the portal interface, and providing multilingual support can enhance compliance.

Example: During filing deadlines, the portal often slows down for millions of taxpayers. Improved infrastructure would ensure timely return filing and reduce penalties.

3. Support MSMEs

MSMEs are the backbone of India’s economy but often struggle with GST compliance. Offering simplified quarterly returns, digital training, and advisory services can reduce operational burdens and encourage formalization.

Example: Introducing simplified quarterly returns for small traders and artisans can encourage registration and regular compliance, while also boosting ITC utilization.

4. Faster Refund Mechanisms

Delayed GST refunds, especially for exporters and service providers, affect liquidity and working capital. Ensuring timely refunds will increase trust in the GST system and encourage reinvestment.

Example: Exporters frequently wait months for refunds on export duties, which can hinder production scaling. Automated tracking and faster processing would solve this.

5. Stable Tax Policies
Frequent changes in GST rates, rules, or filing deadlines create uncertainty for businesses and affect long-term planning. Maintaining stable policies encourages investment, pricing stability, and better financial planning.

Example: Automobile manufacturers and real estate developers require consistent tax rules to plan project costs and pricing strategies efficiently.

6. Expand Tax Base

While GST has formalized many businesses, a significant portion of the informal economy remains outside the system. Educating small traders, street vendors, and rural entrepreneurs about GST benefits can improve compliance and revenue mobilization.

Example: Outreach programs targeting small businesses in Tier 2 and Tier 3 cities can help bring them into the formal economy, expanding the tax base.

Conclusion

GST has significantly restructured India’s indirect tax system, improving compliance, formalization, and economic efficiency. Large industries and FMCG sectors have benefited, while MSMEs face compliance challenges. Continued reforms, digital support, and simplified processes will maximize GST’s positive impact, making it a vital driver of India’s economic growth.
