Concept of Goods and Services Tax (GST)

F Introduction

The Goods and Services Tax (GST) is one of the most significant tax reforms introduced in India to simplify and unify the indirect tax system. It replaced multiple central and state indirect taxes with a single, comprehensive tax on the supply of goods and services. Backed by constitutional amendments and detailed legislation, GST aims to create a common national market, reduce the tax burden on businesses, and ensure transparency in taxation. By introducing a dual tax structure, cooperative decision-making through the GST Council, and a technology-driven compliance system, GST has transformed the way indirect taxes are levied and administered in India.

 

F Constitutional and Statutory Framework of GST

 

Ø  The Constitution (122nd) Amendment Act, 2017

The Constitution (122nd) Amendment Act laid the constitutional foundation for GST in India. It amended the Constitution to empower both the Central and State Governments to levy GST on the supply of goods and services. The Amendment:

1.      Article 246A: Gives both Centre and States the power to make laws and collect GST on the supply of goods and services.

2.      Article 279A: Provides for the creation of the GST Council, which decides GST rates, exemptions, and rules.

It also helped merge many old indirect taxes (like VAT, excise duty, service tax) into a single tax called GST.

This amendment ensured constitutional validity and uniformity in GST implementation across the country.

Ø  Central Goods and Services Tax Act, 2017

The Central Goods and Services Tax Act, 2017 lays down the rules for charging and collecting GST by the Central Government on intra-State supplies of goods and services (supplies made within the same State).

It clearly explains:

1.      Taxable event – GST is charged on the supply of goods or services,

2.      Levy and collection of tax – how and when GST is collected by the Centre,

3.      Input Tax Credit (ITC) – allowing taxpayers to reduce tax by claiming credit of GST already paid on purchases,

4.      Registration, returns, assessment, and penalties – procedures for registering under GST, filing returns, assessment of tax, and penalties for non-compliance.

The CGST Act tells taxpayers how the Central Government applies GST and how compliance is to be followed.

 

F Dual GST Model

India follows a Dual GST Model, which means both the Central Government and State Governments have the power to collect GST on the same transaction.

Ø  Central GST (CGST): Collected by the Central Government on supply of goods or services within a State.

Ø  State GST (SGST): Collected by the State Government on the same intra-State supply.

Ø  Integrated GST (IGST): Collected by the Central Government on inter-State supplies (between two States) and on imports. The IGST amount is later shared between the Centre and the States.

In simple terms:

Ø  If a sale happens within a State → CGST + SGST apply.

Ø  If a sale happens between States or goods are imported → IGST applies.

This model helps maintain federal balance by giving revenue to both Centre and States, while ensuring uniform taxation across India.

 

F GST Council

The GST Council is a constitutional body created under Article 279A of the Constitution of India. It acts as the main decision-making authority for GST in the country.

Its key functions include:

Ø  Recommending GST tax rates, exemptions, and threshold limits,

Ø  Framing GST laws, rules, and procedures,

Ø  Resolving disputes between the Central Government and State Governments or among States.

The GST Council ensures that all GST-related decisions are taken jointly by the Centre and the States, promoting cooperation, uniformity, and smooth administration of GST across India.

 

F Central GST and Application of GST

Central GST (CGST) is applicable on intra-State supplies of goods and services, that is, when the supply takes place within the same State.

Under GST law, tax is charged on “supply”, which has a very wide meaning. It includes:

Ø  Sale of goods or services,

Ø  Transfer of ownership or rights,

Ø  Purchase,

Ø  Barter or exchange of goods or services,

Ø  Grant of license,

Ø  Lease or rental of property or services,

Ø  Import of goods and services.

GST is not limited to sales alone. Any form of transaction where goods or services are supplied for consideration is covered under GST. This wide scope ensures that almost all commercial activities involving goods and services are brought under the GST system, making taxation more comprehensive and uniform.

 

F GST on Imports and Exports

Ø  Imports:
Under GST, imports are treated as inter-State supplies. Therefore, IGST is charged on imported goods and services, along with applicable customs duties. This ensures that imported goods are taxed in the same way as goods produced within India, creating a level playing field for domestic industries.

 

Ø  Exports:
Exports are treated as zero-rated supplies, which means no GST is charged on exported goods or services. Exporters are allowed to claim a refund of the Input Tax Credit (ITC) paid on inputs used in making exports.


Imports are taxed to protect domestic producers, while exports are relieved from GST to make Indian goods and services more competitive in the global market. This system encourages exports and supports India’s economic growth.

 

F Impact of GST on GDP and Inflation

GST has contributed to:

Ø  Improved GDP growth:

GST has made a positive contribution to the Indian economy in several ways. By creating one common national market, GST has removed barriers between States, improved logistics efficiency, and reduced transportation and transaction costs. This has helped businesses operate more smoothly and has supported overall GDP growth.

Ø  Moderation of inflation:

In terms of prices, GST has helped control inflation in the long run by eliminating the problem of tax on tax (cascading effect) that existed under the earlier indirect tax system. Although there were some short-term price changes when GST was first introduced, the system has gradually brought stability.

F Benefits of GST

GST has created a simpler, transparent, and business-friendly tax system across trade, e-commerce, and services sectors.

Ø  Benefits to Trade and Industry

GST has replaced many indirect taxes with a single tax system, reducing complexity. The availability of seamless input tax credit lowers the tax burden by avoiding double taxation. As a result, the cost of production and distribution decreases, making Indian businesses more competitive.

  1. Reduction in multiple indirect taxes,
  2. Seamless input tax credit,
  3. Lower cost of production and distribution.

Ø  Benefits to E-commerce

GST provides uniform tax rates across all States, removing confusion caused by different State taxes. Centralized registration and return filing have simplified compliance. It has also increased transparency in online transactions, helping regulate the digital market effectively.

  1. Uniform tax rates across States,
  2. Simplified compliance through centralized registration,
  3. Increased transparency in online transactions.

Ø  Benefits to Services Sector

GST has removed the overlap between Service Tax and VAT, creating a single, clear tax structure. Service providers can now claim input tax credit on both goods and services, reducing overall tax costs and making compliance simpler.

  1. Removal of overlapping service tax and VAT,
  2. Availability of input tax credit on goods and services,
  3. Simplified tax structure for service providers.

 

F Goods and Services Tax Network (GSTN) Portal

The Goods and Services Tax Network is the technological backbone of GST. It provides a single online platform for all GST-related activities.

Ø  Registration of taxpayers,

Ø  Filing GST returns,

Ø  Payment of taxes,

Ø  Claiming refunds.

The GSTN connects taxpayers, tax authorities, and banks on one digital system. This online platform improves transparency, efficiency, and ease of doing business, while reducing paperwork and manual procedures.

 

F Tax Invoice under GST

A tax invoice is an important document under the GST system. It is issued by a registered GST supplier whenever goods or services are supplied.

Ø  Description of goods or services,

Ø  Value and rate of GST,

Ø  Amount of tax charged,

Ø  GSTIN of supplier and recipient.

A tax invoice acts as proof of supply and tax payment. It is also essential for claiming Input Tax Credit (ITC), as buyers can claim credit only when a valid tax invoice is available.

 

F Dispute Settlement Mechanism under GST

The GST system provides a clear dispute resolution mechanism to handle disagreements between taxpayers and tax authorities, as well as between the Centre and the States.

Ø  Adjudication by tax authorities, where disputes are first examined and decided,

Ø  Appeals to Appellate Authorities and the Appellate Tribunal, allowing taxpayers to challenge incorrect or unfair orders,

Ø  Resolution of Centre–State and inter-State disputes through the GST Council, ensuring cooperative federal decision-making.

In simple words, this mechanism ensures fairness, legal certainty, and protection of taxpayer rights, while maintaining uniformity and transparency in GST administration.
