Understanding Goods and Services Tax
The Goods and Services Tax (GST) represents one of the most transformative reforms in the history of Indian taxation. Introduced through the 101st Constitutional Amendment Act, 2016, and implemented on 1 July 2017, GST replaced a fragmented system of multiple indirect taxes with a unified, destination-based, value-added tax applicable on the supply of goods and services. The primary objective behind GST was to simplify the indirect tax structure, eliminate the cascading effect of taxes, promote ease of doing business, and integrate the Indian market into a single economic space.
From a constitutional perspective, GST draws its legislative authority from Article 246A, which grants both Parliament and State Legislatures concurrent power to enact GST laws. This unique provision marks a departure from traditional fiscal federalism by allowing shared legislative competence. Furthermore, the GST Council, created under Article 279A, functions as a cooperative federal body responsible for making key recommendations on rate structures, exemptions, and administrative policies. In Union of India v. Mohit Minerals Pvt. Ltd., the Supreme Court clarified that GST Council recommendations, while highly persuasive, are not binding on governments, reinforcing India’s quasi-federal structure.
Features and Structure of GST in India
GST is designed as a multi-stage, value-added, destination-based levy. Tax is collected at each stage of the supply chain, but businesses are allowed to claim Input Tax Credit (ITC), ensuring that tax is effectively charged only on the value addition. This framework prevents tax pyramiding, which was a major concern under the earlier indirect tax regime.
CGST, SGST, IGST, and UTGST
GST is divided into four components to preserve the federal character of taxation:
- CGST (Central GST): Collected by the Union Government on intra-state supply.
- SGST (State GST): Collected by State Governments on intra-state supply.
- IGST (Integrated GST): Levied on inter-state supply of goods and services and imports; collected by the Centre and shared with States.
- UTGST (Union Territory GST): Applicable in union territories without legislatures.
This distribution ensures balanced revenue sharing and financial autonomy for both Union and State governments. The Supreme Court, in State of Kerala v. Kannan Devan Hills Plantations, observed that GST maintains fiscal symmetry while upholding cooperative federalism.
Objectives of GST
GST was implemented with several key objectives such as:
- Creating a unified national market
- Improving tax compliance through digitization
- Enhancing ease of doing business
- Eliminating double taxation and cascading effects
- Increasing transparency and accountability
- Strengthening the formal economy
In R.K. Garg v. Union of India, though related to economic legislation generally, the Court recognized that economic reforms must be assessed with deference to legislative wisdom, an approach relevant to GST’s transformative nature.
Input Tax Credit (ITC) Mechanism
The ITC mechanism forms the backbone of GST’s efficiency. Businesses can claim credit for taxes paid on inputs used for supplying taxable goods or services. This ensures that the tax is ultimately borne by the final consumer, not businesses in the value chain.
Under Section 16 of the CGST Act, taxpayers must satisfy conditions such as possession of a valid tax invoice, receipt of goods or services, and payment of tax by suppliers. Judicial clarity was provided in Safari Retreats Pvt. Ltd. v. Chief Commissioner of CGST, where the Orissa High Court discussed ITC claims related to immovable property, reflecting the complexity of ITC disputes.
GST Rate Structure
The GST Council has categorized goods and services into multiple slabs — 0%, 5%, 12%, 18%, and 28%, with additional cess applicable on items like tobacco and luxury automobiles. This multi-slab structure reflects India’s social and economic diversity. Courts have held that rate classification falls under legislative and policy domain, as reiterated in Bajaj Auto Ltd. v. State of Maharashtra, where economic classifications were upheld unless palpably arbitrary.
Registration and Compliance
GST mandates registration for businesses whose aggregate turnover exceeds prescribed thresholds (usually ₹20 lakhs for services and ₹40 lakhs for goods, subject to state variations). Registered taxpayers must comply with:
- Filing monthly, quarterly, and annual returns
- Maintaining digital records
- Adhering to e-invoicing standards
- Ensuring accurate payment of taxes
Failure to comply attracts penalties under the CGST Act. Courts have emphasized procedural fairness, as seen in M/s Shree Nanak Ferro Alloys Pvt. Ltd. v. Union of India, particularly regarding cancellation of GST registration.
Reverse Charge Mechanism (RCM)
Under RCM, the recipient of the goods or services, not the supplier, pays GST. This applies in circumstances such as purchase from unregistered dealers or supplies notified by the government. The purpose is to prevent revenue leakage and ensure tax compliance in sensitive sectors.
GST Litigation: Common Areas of Dispute
Even though GST aims for simplicity, disputes frequently arise regarding:
- ITC denial
- Classification disputes
- Transitional credit under Section 140
- Registration cancellation
- Rate applicability
- Place of supply rules
The judiciary continues to refine GST jurisprudence. In Filco Trade Centre Pvt. Ltd. v. Union of India, the Supreme Court directed reopening of the GSTN portal for transitional credit claims, highlighting the importance of procedural justice during implementation.
Challenges of GST
Despite its strengths, GST faces challenges such as:
- Complex return filing
- Frequent rate changes
- Technical difficulties in the GSTN portal
- High compliance burden for small businesses
- Ambiguity in classification disputes
However, ongoing reforms aim to simplify procedures, reduce litigation, and enhance technological efficiency.

Conclusion
GST signifies a paradigm shift from origin-based taxation to a destination-based, technologically driven indirect tax system. By unifying various taxes into a single structure, GST promotes transparency, efficiency, and economic integration. For law students, understanding GST requires a strong grasp of constitutional provisions, statutory mechanisms, and emerging jurisprudence. The transformation brought by GST continues to shape India’s fiscal landscape, ensuring a modern, streamlined approach to indirect taxation.
