Goods and Services Tax and Cooperative Federalism in India: An Empirical Analysis of Karnataka

Abstract The introduction of the Goods and Services Tax (GST) in July 2017 has been a paradigm shift in India’s fiscal federalism, changing the dynamics between the Union and the States in India. This paper aims to analyze the interface between GST and cooperative federalism, with particular empirical focus being given to one state, namely, Karnataka. The empirical analysis will be conducted to assess whether the 'Grand Bargain' of GST has been able to achieve cooperative federalism in India. The empirical analysis conducted for the state of Karnataka has shown remarkable resilience and growth in tax collection due to the state’s digital infrastructure and dominance of services in the economy. However, there are some issues with regard to fiscal autonomy and compensation mechanisms, as discussed in this paper. The empirical analysis conducted in this paper has shown that GST has been able to achieve cooperation, and the sustainability of this federal system depends upon further building up this consensus and technology integration.

The GST has been characterized as a "Grand Bargain," where states have given up sovereignty over taxation in exchange for a share in GST, which is a consumption tax. This was not just a tax reform, but rather constitutional re-engineering in Centre-State financial relations, based on cooperative federalism principles. Before the introduction of GST, India’s fiscal system was marked by a fragmented tax base, cascading effect of taxes, and high entry hurdles for trade between states. The introduction of GST was intended to establish a ‘one nation, one tax’ market. However, the compromise in fiscal autonomy raised questions regarding revenue security and federalism in India. In this context, the case study of the state of Karnataka assumes significant importance. Being at the forefront in tax reforms and having a strong service sector, Karnataka’s GST experience is critical in assessing the empirical success of cooperative federalism in India. This paper seeks to examine the operational mechanism of GST and empirically assess Karnataka’s fiscal performance in this context. 2.Objectives To evaluate the effectiveness of the GST 'Grand Bargain' in achieving the ideals of cooperative federalism in the country through the creation of institutions like the GST Council. To empirically evaluate the trends and growth rates of Karnataka's GST revenues, tax buoyancy, and compliance vis-à-vis the national averages from 2017-2023. To evaluate the significance of the dominant services sector and the digital infrastructure in Karnataka in the success of the GST regime. To evaluate the challenges in the path of fiscal autonomy, compensation, and cooperative federalism in the context of Karnataka. 3.Methodology This study adopted a descriptive and analytical research design. The analysis is based on secondary data retrieved from the Ministry of Finance (India), the GST Council, the Comptroller and Auditor General (CAG) reports, and the Directorate of Economics and Statistics, Karnataka. Key metrics analyzed include: GST Revenue Trends: A comparative study of pre-GST (VAT/Service Tax Period) and post-GST (2017-2023) revenue collection trends. GSTR Filing Compliance: Figures regarding GSTR return filing compliance in Karnataka in comparison to the national average. State Share in National Collection: Figures regarding the state’s share in the national GST collection for a period of five years. 4.Review of Literature Theoretical Framework of Cooperative Federalism According to Rao & Singh (2005), the Indian system of fiscal federalism has traditionally swung between centralization and cooperation. They asserted the need for tax harmonization as a requirement of a common market, but warned of the need for a credible mechanism of compensation. In the GST system, the GST Council has filled the role of providing the required compensation. Kaur & Kaur (2018) described the GST Council as a unique federal institution, where the Centre and the States share powers, moving away from the hierarchical approach to a collaborative approach. Fiscal Impact and Revenue Neutrality There are different views on the revenue implications of GST. Purohit (2016) in his study on "Revenue Neutral Rate" explained that states that have higher industrial growth will gain from GST. In addition, other states will face a deficit due to high consumption. The empirical evidence on revenue implications is varied. In a study by the National Institute of Public Finance and Policy, although GST expanded the tax base, initial compliance costs affected revenue growth in certain states (NIPFP, 2019). The Karnataka Context The literature on the specific case of Karnataka remains scarce. However, Isaac & Tharakan (2018) pointed out that the commercial tax administration of Karnataka ranked as the most digitalized even prior to the implementation of GST. Moreover, the Economic Survey of Karnataka (2022) revealed that the high level of compliance in the state could be attributed to the dominance of the IT industry, which provides a paper trail of transactions, thus reducing the possibility of tax evasion. The purpose of the present paper is to fill the gap between the theoretical construct of cooperative federalism and the empirical data on the fiscal developments in the state of Karnataka. 5.Analysis and Discussion The GST Council: Institutionalizing Cooperation The GST Council is the epitome of cooperative federalism. The GST Council follows a voting system in which the Centre has one-third weightage and states have two-thirds weightage. A three-fourths majority is required to make decisions. From an empirical point of view, it can be stated that the GST Council has been able to settle disputes through consensus. Over 500 recommendations have been made by the GST Council till 2023. The formal voting system has been minimal. This is a clear reflection of the high level of cooperation. The previous system had the Empowered Committee of State Finance Ministers, which was only recommendatory in nature. The rationalization of tax rates during the COVID-19 pandemic for essential drugs is a reflection of the federal cooperative system. Empirical Analysis of Karnataka Revenue Performance and Tax Buoyancy. The state has always been performing better than the national average in GST revenues. In the fiscal year 2022-23, Karnataka has reported a growth in revenues to the tune of around 20% compared to the previous year, which is far higher than the all-India average (Reserve Bank of India, 2023). Table 1: Karnataka GST Revenue Trends (Selected Years) Financial Year Gross GST Collection (INR Crore) Growth Rate (%) 2018-19 73,487 Base Year 2019-20 79,245 7.8% 2020-21 71,432 -9.8% (COVID) 2021-22 95,367 33.5% 2022-23 114,500 (Approx.) 20% Note: Data adapted from Karnataka Economic Survey and RBI State Finances Reports. The data shows that the state has been able to recover from the initial hiccups faced during the implementation of the GST and the pandemic. The share of the state in the overall GST revenue collected is around 9-10%, which is much higher than the state’s share in the overall GDP of India, which is around 6-7%. The Service Sector Effect. An interesting phenomenon has been the gain earned by the state of Karnataka from the imposition of service tax. In the pre-GST regime, states were prohibited from taxing the service sector, which fell under the Central government's jurisdiction. However, the state of Karnataka, with Bengaluru being the hub of the "Silicon Valley of India," has a service sector, which contributes more than 65% to its GSDP. The GST regime enabled the imposition of State GST on the service sector, thus compensating the loss of revenue from the imposition of Octroi and Entry Tax, thereby substantiating the claim of the GST regime being more favorable to service-oriented states. Compliance and Technology. The success of Karnataka in empirical terms is also a function of administrative efficiency. Karnataka was the first state to fully implement the "E-invoicing" system. The state’s Commercial Taxes Department reports that the number of active taxpayers has grown by more than 25% since the introduction of the GST regime due to data matching and analytics-based enforcement. This is the "cooperative" aspect, wherein the state leveraged the Centre’s technology infrastructure (GSTN) to improve its own administration. 6.Challenges to Federalism However, despite this empirical success, the cooperative spirit has been put to test. The delay in the payment of compensation by the Centre during the pandemic (2020-2021) forced Karnataka to raise funds through the market, thus increasing its fiscal deficit. Moreover, the discontinuation of the compensation regime in June 2022 has also put Karnataka's ability to maintain revenue growth without the cover of 14% annual growth through the compensation regime into question. However, as can be seen from the latest data for Karnataka, the expansion of the tax base has helped to mitigate this problem, which is beyond the capabilities of many other states in India. Conclusion A discussion of the empirical analysis of Karnataka presents a nuanced view of the GST and cooperative federalism. The state can be considered as a success story where the loss of fiscal autonomy has paid dividends in terms of the expansion of the tax base and access to revenue in the service sector. The GST Council has been able to institutionalize cooperative federalism and replace the fr
