Abstract The informal sector plays a vital role in Karnataka’s economy by providing employment and supporting livelihoods for a large segment of the population. However, its unregulated nature, low productivity, and limited integration with formal systems have historically constrained its growth. The introduction of the Goods and Services Tax (GST) in 2017 marked a significant shift in India’s indirect tax structure, aiming to enhance transparency, streamline taxation, and promote economic formalization. This paper examines the transformation of the informal sector in Karnataka in the post-GST era. GST has encouraged many informal enterprises to register under the tax system due to provisions such as input tax credit and compliance requirements, thereby fostering formalization. This transition has improved tax compliance, increased government revenue, and enabled small businesses to access institutional finance and broader markets. At the same time, the shift has posed challenges, including increased compliance costs, the need for digital literacy, and operational adjustments for small traders and micro-enterprises. In Karnataka, where small-scale industries and service providers form a significant part of the economy, these changes have led to both opportunities for growth and short-term disruptions. The study highlights that while GST has been instrumental in integrating the informal sector into the formal economy, its success depends on supportive measures such as simplified procedures, digital awareness, and policy assistance. Overall, GST represents a transformative reform that has reshaped the structure and functioning of the informal sector in Karnataka, though its long-term impact continues to evolve.

This sector includes street vendors, small traders, artisans, construction workers, and micro-enterprises that often operate outside formal regulatory frameworks. While the informal economy provides employment to a large segment of the population and contributes substantially to output, it is typically characterized by low productivity, lack of social security, limited access to institutional finance, and minimal tax compliance. The introduction of the Goods and Services Tax (GST) on 1st July 2017 marked a major structural reform in India’s taxation system. GST replaced multiple indirect taxes with a unified, destination-based tax system aimed at enhancing transparency, improving compliance, and creating a common national market. As a technology-driven and comprehensive tax regime, GST requires businesses to register, file returns online, and maintain systematic records of transactions. This shift has had profound implications for the informal sector, particularly in states like Karnataka with a vibrant base of micro, small, and medium enterprises (MSMEs). One of the most significant transformations triggered by GST is the gradual formalization of the informal economy. By mandating registration for businesses crossing specified turnover thresholds and enabling input tax credit (ITC) only through registered entities, GST has incentivized informal businesses to enter the formal system. This has increased the number of registered taxpayers and improved tax compliance across sectors. In Karnataka, industrial clusters such as Bengaluru and Peenya have witnessed increased formal participation as firms adapt to GST requirements to remain competitive and integrated within supply chains. However, this transition has not been without challenges. The informal sector, traditionally reliant on cash transactions and simple accounting practices, has faced difficulties in adapting to GST’s compliance requirements. The need for digital literacy, regular return filing, and maintenance of records has increased the cost of doing business for small enterprises. Many small traders and service providers in Karnataka have had to rely on tax consultants or adopt new technologies, which has added to their operational burden. Furthermore, disruptions in cash-based transactions and initial confusion regarding tax rules have impacted business continuity and employment in certain segments. Despite these challenges, GST has also created opportunities for growth and integration. Formalization enables businesses to access institutional credit, participate in organized markets, and expand beyond local boundaries. It also enhances transparency and accountability, reducing tax evasion and promoting fair competition. Over time, GST is expected to improve productivity and efficiency in the informal sector by encouraging better business practices and technological adoption. In the context of Karnataka, recent developments highlight both the progress and tensions associated with GST-driven transformation. Increased use of digital payment systems such as UPI has made transactions more traceable, thereby bringing informal businesses under the tax net. While this has strengthened compliance, it has also raised concerns among small traders regarding tax burdens and regulatory complexity, sometimes even pushing them back towards cash-based transactions. These dynamics underscore the need for balanced policy measures, including awareness programs, simplified compliance procedures, and support mechanisms for small businesses. GST has acted as a catalyst for transforming the informal sector in Karnataka by promoting formalization, enhancing transparency, and integrating businesses into the broader economic system. At the same time, the transition poses significant challenges that require careful policy intervention to ensure that the benefits of formalization are inclusive and sustainable. The evolution of the informal sector under GST thus represents a complex interplay between reform-driven modernization and the realities of grassroots economic structures. 2.Review of Literature A number of studies have examined the impact of the Goods and Services Tax (GST) on India’s informal sector, with particular attention to issues of formalization, compliance, and economic transformation. The literature reveals a mix of positive outcomes and significant challenges, especially for micro and small enterprises that dominate the informal economy. Madhav Anand (2022) conducted a critical evaluation of GST’s impact on the informal sector and found that the reform has contributed to increased formalization and higher taxpayer registration. However, the study also highlights that GST imposed higher compliance costs and disrupted traditional cash-based transactions, particularly affecting sectors such as retail, construction, and textiles. The research concludes that while GST improves transparency and tax compliance, it creates transitional difficulties for informal businesses. Shikha Mogra (2025), in a case study of MSMEs in Indore, examined how small enterprises have adapted to GST. The study emphasizes that GST has encouraged businesses to adopt formal accounting systems and comply with tax regulations. At the same time, it identifies challenges such as lack of awareness, technological barriers, and increased administrative burden, which affect the sustainability of small informal firms. Singh and Singh (2024) analyzed compliance costs and coping strategies in the unorganized sector. Their findings indicate that GST represents a major overhaul of the indirect tax system, benefiting organized firms more than informal ones. The study points out that informal enterprises face difficulties in meeting compliance requirements, including return filing and digital record maintenance, thereby increasing operational costs and complexity. Vinod Kumar (2025) examined GST from a broader economic perspective and noted that the reform has improved industrial efficiency by eliminating cascading taxes and promoting ease of doing business. The study suggests that GST has created a more transparent and unified tax structure, which indirectly encourages the informal sector to integrate into the formal economy. At the regional level, Harshith Kumar Shetty (2024) analyzed the implementation of GST in Karnataka and highlighted its technology-driven nature. The study notes that GST requires online registration, return filing, and compliance, which has accelerated digitization and improved administrative efficiency. However, it also implies that such requirements can be challenging for small and informal businesses lacking digital literacy. Further, Harishankar and Manoj (2021) studied the impact of GST on small-scale industries in the Peenya industrial area of Bengaluru. Their findings reveal mixed responses, with some firms benefiting from tax simplification and input tax credit, while others struggle with compliance and increased operational costs. The study underscores that GST has significantly altered the functioning of small enterprises in Karnataka. Overall, the existing literature suggests that GST has acted as a catalyst for formalization and structural transformation of the informal sector. However, it has also introduced compliance challenges, increased costs, and required technological adaptation. The studies collectively highlight the need for supportive policies, awareness programs, and simplified procedures to ensure that the informal sector in Karnataka can fully benefit from GST reforms. 3.Objective: To examine the impact of the Goods and Services Tax (GST) on the formalization and transformation of the informal sector in Karnataka. 4.Methodology This study on the transformation of the informal sector through the Goods and Services Tax (GST) in Karnataka is based exclusively on secondary sources of da
