What is GST? (Goods and Services Tax)

The full form of GST is Goods and Services Tax. It was first introduced in the Budget Speech presented on 28th February 2006. It laid the foundation for a complete reform of India’s indirect tax system. Finally implemented on 1st July 2017 as the Goods and Services Tax Act, the indirect taxation system thus went through a chain of amendments since its inception.

With this tax reform, GST replaced multiple indirect taxes that were levied on different goods and services. The Central Board of Indirect Taxes and Customs (CBIC) is the regulatory body governing all changes and amendments regarding this tax.

GST Meaning and Scope

GST definition is easy to decode. It is a destination-based, multi-stage, comprehensive tax levied at each stage of value addition. Having replaced multiple indirect taxes in the country, it has successfully helped the Indian Government achieve its ‘One Nation One Tax’ agenda.

The tax is levied on goods and services sold within India’s domestic boundary for consumption. Implemented by a majority of nations worldwide with respective customisations, the tax has been successful in simplifying the indirect taxation structure of India.

GST is levied on the final market price of goods and services manufactured internally, thereby reflecting the maximum retail price. Customers are required to pay this tax on a purchase of goods or services as an inclusion in their final price. Collected by the seller, it is then required to be paid to the government, thus implying the indirect incidence.

The GST rates on different goods and services are uniformly applied across the country. Goods and services have, however, been categorised under different slab rates for tax payment. While luxury and comfort goods are categorised under higher slabs, necessities have been included in lower and nil slab rates. The main aim of this classification is to ensure the uniform distribution of wealth among residents of India.

History of GST and GST Information

Back in 2000, the then Prime Minister of India introduced the concept of Goods and Services Tax. He also formed a committee to draft new indirect tax law.

List of Taxes Subsumed after GST Implementation

Good service tax was introduced as a comprehensive indirect tax structure. With this introduction, the government aimed to consolidate all indirect taxes levied under one umbrella.

Thus, except for customs duty that is levied on the import of goods, Goods and Services Tax replaced multiple indirect taxes. This introduction helped overcome the limitations of its previous indirect tax structure regarding implementation and inefficiency in the collection process. 

Following is the list of indirect taxes that were subsumed by Goods and Service Tax-

  • Indirect Taxes Imposed by the Central Government

  • Central Sales Tax
  • Service Tax
  • Central Excise Duty
  • Excise Duty (Additional)
  • Countervailing Duty or Additional Customs Duty
  • Special Additional Customs Duties
  • Indirect Taxes Imposed by the State Government

  • State VAT
  • Entry Tax and Octroi Duty
  • Luxury Tax
  • Amusement and Entertainment Tax
  • Taxes on Advertisements
  • Goods and services related to cess and surcharges
  • Purchase Tax
  • Tax on betting, lottery and gambling.

Objectives of GST

The key objectives of GST are-

  • 'One Nation, One Tax’

GST took the place of many indirect taxes that existed before. It was introduced with a core motive and policy called the 'One Nation, One Tax’. It was introduced as so to provide set tax rates for a service/product that every state would follow. It even simplified administering taxes and compliances.

  • To Subsume Indirect Taxes in India   

To create a centralised and unified tax system on goods and services, GST was introduced in India. Under its laws, the majority of indirect taxes were subsumed into one to simplify administration.

  • To Restrain Tax Evasion

Prior to the introduction of GST, the tax evasion rate was very high. In order to curb evasion and create a centralised tax surveillance system, GST was introduced in India. It has effectively contributed to reducing the number of tax defaulters.

Types of GST and GST Rules

GST can be divided into four sections based on the kind of transaction it involves. Before a business can determine its GST liability, assessing the following table about the Components of GST is essential.

Components of Goods and Services Tax

What does it mean?

State Goods and Services Tax (SGST) 

SGST refers to the tax payable on the sale of services and products within a state. 

It replaces previous taxes, including Value Added Tax, Entry Tax, State Sales Tax, Entertainment Tax, surcharges and cesses.

Central Goods and Services Tax (CGST)

The tax levied on the supply of intra-state products is CGST. The Central Government charges this tax. 

CGST replaced many taxes levied by the Centre, including Service Tax, Central Excise Duty, CST, SAD, Customs Duty, etc. 

Union Territory Goods and Services Tax (UTGST)

Taxes applicable to the sale of products and services in Union Territories, such as Andaman and Nicobar, Daman and Diu, Chandigarh, Dadra, etc. 

Integrated Goods and Services Tax (IGST)

The sale of inter-state products and services leads to taxation. This is IGST. Basically, when businesses transfer services and products from one state to another, they need to pay this form of GST.  

Collection of tax is thus undertaken in the following way for intra-state and inter-state transactions.

GST Levy and Revenue Share

Intra-State Sale

Inter-State Sale

Goods and Services Tax 



Share of Revenue

Revenue collected to be shared between state and central government equally.

Revenue collected by the central government. It will then be shared as per the goods’ destination.


Here’s an example to help you understand the levy, collection and share of revenue between the state and the central government.

A seller in Maharashtra sells goods worth Rs. 1 lakh to a buyer in the same state. The tax rate applicable to the goods is 12%, comprising 6% of CGST and 6% of SGST. The total GST of Rs. 12,000 collected will be shared between the centre and the state at Rs. 6,000 each as the sale is made intra-state.

The same seller sold goods worth Rs. 50,000 from Maharashtra to Karnataka. The tax rate applicable to these goods was 18%. The seller will thus charge IGST of Rs. 9,000 from the buyer due to it being an inter-state sale. The tax collected will be submitted to the central government.

Once submitted, the tax will be shared by the central government and state government based on the supply of goods made. For ease of tax collection, the government has made the entire system for the payment of GST online.

Understanding the Dual Structure of Goods and Services Tax

Unlike a federal structure where the government collects taxes and distributes them to the states, a dual tax structure allows both the centre and the state to levy and collect taxes.

Goods and Services Tax in India carries this same dual structure, thus having two components, state as well as a central levy. The structure is applicable to all transactions related to goods and services.

Concepts of GST Levy – Multi-Stage, Destination-based and Value Added

The comprehensive nature of the Goods and Services tax levy takes into account every stage of manufacture whereby value-added to an item is taxable. Plus, a change of destination also attracts GST

The various stages of GST application are discussed below - 

  • Meaning of Multi-stage Levy

From production/manufacture to consumption, an item is passed from one link of the supply chain to another until it is finally purchased for consumption. An indirect tax is hence, levied at every stage, to be borne ultimately by a consumer.

The different steps of production of a finalised good and its corresponding sale in the market comprise the following in general.

  • Raw material purchase
  • Manufacture/production of raw materials into finished goods
  • Storage of finished goods at the warehouse
  • Sale of goods to the wholesaler
  • Sale of goods to the retailer
  • Sale to an end-user/consumer

GST charged at each link of this chain makes it a multi-stage tax.

  • Meaning of Destination-based Levy

A destination-based levy means the item is to be taxed at a place where it is consumed and not at its origin.  This means that the location where an item is consumed will rightfully collect the tax.

In this context, it is essential to differentiate the concept of ‘supply’ from ‘place of supply’.  The decision regarding whether a sale is intrastate or interstate will be taken accordingly. 

  • Meaning of Taxation on Value Addition

The concept of GST on value addition implies every addition made to an item to make it saleable to the end-user is taxable under this regime. Understand it with the help of an example.

The manufacturing unit of Britannia Industries Limited in Chennai, Tamil Nadu, manufactures a variety of biscuits. During the manufacturing process, it goes through the following stages, with value added at each stage.

  • Processing flour, sugar and other materials into a dough and baking into biscuits increases the value of the material by making it saleable as units.
  • The biscuits are then sent to the warehousing agent for storage and further processing. He then packs the biscuits in sets of 10 for the next stage of the process. It is another value addition as it increases the monetary value of the biscuits, making them saleable.
  • Each packed unit is labelled as a product with Britannia’s brand logo. The act of labelling is the next stage of value addition.
  • The biscuits are packed in smaller cartons and re-labelled to be transported and sold to the retailer, crossing another stage of value addition.

Thus, for each monetary value added to these stages, making the product saleable, GST is levied, thus making it a tax on value addition.

Composition Scheme under GST

The composition scheme under GST eases the process of indirect tax payment for small taxpayers. As per the CBIC, companies with an annual turnover within Rs. 1 Crore can opt for the scheme to pay their taxes. For North-Eastern states, the turnover limit is Rs. 75 Lakh. Registration under the scheme is, however, voluntary.

The rates applicable under the composition scheme include the following.

Business Type

Rate of CGST

Rate of SGST

Total GST Rate

Goods traders and manufacturers




Restaurants that do not serve alcohol




You must, however, also meet a set of conditions to avail of the scheme. A taxpayer needs to file GST CMP-02 when opting for the scheme. They can do so at the GST online portal.

Concept of Input Tax Credit (ITC) under GST in India

An Input Tax credit means that when a business person or a trader is paying tax on output, he/she can reduce the tax already paid on input (purchase).

For example, in the case of a manufacturer selling the final product, the output tax stands at Rs. 450. However, he already paid Rs. 300 as input tax while purchasing the product. He can thus receive an ITC of Rs. 300 on the final product and needs to pay only the difference of Rs. 150, i.e., Rs. 450 – Rs. 300 to the government as Goods and Service Tax.

ITC can be claimed only by businesses registered under the Goods and Services Tax Act. Also, all respective suppliers must be registered under the act for you to be eligible to avail of ITC.

Hence, go for Goods & Service Tax registration if you are eligible and not yet registered. Also, file a Goods and Services Tax Return and pay your taxes within the due date to avoid any inconvenience.
