Constitutional Provisions and Legal Framework on Tax Reforms in India in the GST Era: Critical Analysis

Abstract On July 1, 2017, India began the implementation of the Goods and Services Tax (GST), constituting a paradigm shift in the country’s indirect taxation system aimed at creating a single national market by consolidating several central and state taxes. This paper analyzes the constitutional provisions as well as the legal base for these tax reforms in the GST era, stressing the significance of fiscal federalism, economic efficiency, and administrative effectiveness. The framework is based on the 101st Constitutional Amendment Act, 2016, allowing the Centre and states to jointly levy GST whilst creating the GST Council to function as a collaborative body, to harmonise tax policies. The analysis highlights a few of the pertinent legislations such as the Central GST Act, Integrated GST Act, and State GST Acts which specify tax jurisdictions, input tax credits, and compliance mechanisms. It analyzes how these provisions resolve pre-GST inefficiencies such as cascading taxes and interstate barriers to foster seamless trade and revenue buoyancy. Yet the critical lens highlights several ongoing challenges: tax classification ambiguities, dual administrative control impose significant compliance demands for businesses, and tensions within Centre-state relations, particularly in revenue sharing and decision-making within the GST Council. The article investigates challenges of implementation such as technological glitches in the GST Network, its effect on small enterprises, and claims that, though GST has advanced transparency and digitalisation, it has also inadvertently widened inequalities and fiscal dependencies.

India’s previous approach to the indirect state taxation system was one of great complexity and cost overruns of multiple indirect taxes, which were levied at both the state and central levels of government, and that has changed with a single set of laws, introduced by the state (hereafter known as Goods and Services Tax (GST)), in the name of India’s independence. Before GST, we were using an indirect tax structure, troubled by problems like tax cascading: the imposition of a tax on taxes, which would increase the cost of goods and the aggregate volume of goods. These fragmented systems posed challenges for trade between the states due to the inefficiency of the tax regime and for businesses' tax compliance. In India, the inauguration of GST, which was introduced on July 1, 2017, and which was a watershed movement in fiscal history, introduced the GST on July 1, 2017, a tax to reduce various taxes, including VAT, Central Excise Duty and Service Tax, as well as the value added charges at various locations in India. The new tax system meant to reduce the burden of tax was aimed to remove the need for complex tax administration procedures and to facilitate an inclusive and economically driven integration under one country with a harmonization of competition and development by creating a single national market and by promoting economics on the basis of one single nationalised market. Central to this change are certain constitutional mandates and a strong legal backdrop that made it possible to move beyond the VAT and its variants on GST to GST, which is in line with Indian cooperatively federalised concept. Article 246A, 269A, and 279A in the Constitution (101st Amendment) Act, 2016, enabled the Union and States to increase their GST levy at the same time, setting up the GST Council, the principal authority on issues regarding tax rates, exemptions and implementation. This legal framework, bolstered by Acts like the Central Goods and Services Tax (CGST) Act, 2017, and Integrated Goods and Services Tax (IGST) Act, 2017, has served to remove distortions in the taxation hierarchy, and to provide for transparent (and efficient) credit delivery along the supply chain. However, despite some success, a closer inspection shows there are still structural differences among the tax buoyancy, as well as financial compliance and tax disparities that could prevent the full impact of the changes from having been taken off to be realized. 2.Historical Background of Tax Reforms Leading to GST: Indirect tax reforms are rooted in India's post-independence era where early attempts aimed to rationalize taxation by looking at the global tax systems have contributed. From the 1980s, a concept for a value-added tax (VAT) system became popular, which was a precursor to GST. The Modified Value Added Tax (MODVAT) was introduced by the government of Prime Minister Rajiv Gandhi in 1986, who introduced Finance Minister V. P. Singh to provide credit for taxes made on inputs as opposed to output taxes, ultimately alleviating the widespread impact of excise duties. This was an early step towards modernising central indirect taxes. Later reform was based on that groundwork. In 1991 as India's economy made liberalization policies shift toward taxation, Raja Chelliah led the Tax Reforms Committee, which advocated the adoption of a VAT-based system in order to reach a larger base of tax and enhance the efficiency of the tax system. In 1999, while serving as Prime Minister Atal Bihari Vajpayee, a consensus about a single GST was discussed in a number of meetings with economic advisors and in 1999 the committee was established under Asim Dasgupta’s West Bengal Finance Ministry to develop a GST model. The committee concentrated on backend infrastructure and logistics for the common administration of taxation. The Vijay Kelkar Task Force on tax reforms also promoted GST in 2002, saying it could cut the barriers at the state level of trade. State-level VAT commenced in most states in 2005. It replaced the sales tax and was a transition to GST as input tax credits were introduced on a state-by-state basis. The proposed 2006 Union Budget, brought to Parliament by Finance Minister P. Chidambaram, set a bold goal to have GST implementation by April 2010, although political and federal talks were postponed. In 2011, the United Progressive Alliance (UPA) government proposed the Constitution (115th Amendment) Bill in support of GST; however, it lapsed with Lok Sabha dissolution in 2014. Under the National Democratic Alliance (NDA) government, Finance Minister Arun Jaitley brought back the Constitution (122nd Amendment) Bill in 2014. It was passed in 2015 by the Lok Sabha and after amendments by the Rajya Sabha in 2016. Ratified by more than half the states, it underwent Presidential assent on September 8, 2016, through the Constitution (101st Amendment) Act, 2016. This laid the foundation for GST's coming into force in 2017. This historical trajectory implies a gradual shift from fragmented taxes to a total system, motivated by economic efficiency and fiscal integration. 3.Constitutional Provisions of GST: The Constitution (101st Amendment) Act, 2016, is a landmark reform in fiscal federalism in India that allowed for the introduction of the Goods and Services Tax (GST) by amending vital provisions of the Indian Constitution. In this amendment, after the Constitution (122nd Amendment) Bill was passed in 2014 and subsequently ratified by the states, Parliament and the legislatures of the Indian states, at the time had concurrent powers to levy tax on the supply of goods and services, excluding alcoholic liquor for human consumption. Before this, taxing powers were limited to only the Union List (for central taxes such as excise duty) and State List (for state taxes such as sales tax) under India’s Constitution’s Seventh Schedule, leaving a fragmented system susceptible to cascading effects and inter-state obstruction. The new amendment responded to these problems by including new articles and modifying previous Articles to form a unified taxation system and to strengthen the integration of economy and the co-operation of federalism. Article 246A is one of the key inserted by 101st amendment with special provisions for GST act. It gives Parliament and state legislatures the power to make laws on intra-state supplies under GST and Parliament to make decisions on inter-state supplies only. This article replaces earlier distribution of the legislative powers provided for in Articles 246 and 254, allowing for a pre-emption of GST laws in case of clashes leading to a uniform national tax framework. Article 246A reduces jurisdictional overlap and promotes tax administration efficiency; thus also transforming a rigid division of powers among the federal and regional levels. Article 269A deals with the levy and collection of GST on inter-state trade or commerce, and provides that those taxes shall be levied by the central government and apportioned between the Union and the States as recommended by the GST Council in accordance with these laws. In a federal system, this provision guarantees fair sharing of revenue, avoids a confrontation over inter-state transactions, and facilitates smooth transfer of goods and services across borders. Moreover, it resonates with the overarching goal of establishing a unified national market by linking the taxation of imports and exports to the framework of Integrated GST (IGST). The article highlights the constitutional promise of fiscal equity by stipulating that compensation will be available to states if they incur a revenue loss during the implementation of GST, providing that this compensation will last up to five years and be subject to similar amendments. Article 279A constitutes the GST Council under the Constitution under which the Council shall be constituted by the President within 60 days from the inception of the amendment. With the Union Finance Minister serving as the chairperson and all the states having finance ministers, the Council shall make recommendations on taxation rates, exemptions, thresholds, dispute resolution, and is based on one
