Goods and Services Tax: What is GST? | Indirect Tax Law

Goods and Services Tax (GST) in India is like a modern makeover for taxes. It’s a unified system introduced in 2017 that simplifies how we tax things we buy and services we use. Imagine it as one tax to rule them all, replacing various indirect taxes and creating a fairer, more straightforward way of handling business and consumer transactions.  

With different tax rates for different items and a focus on technology, GST is like the tech-savvy superhero of the Indian taxation world, making things clearer, efficient, and less complicated for everyone involved.

What is Goods and Services Tax in India? 

Goods and Services Tax or GST, is a type of indirect tax in India that replaced several other taxes like excise duty, VAT, and services tax. It became effective on July 1, 2017, following the passage of the Goods and Services Tax Act in Parliament on March 29, 2017. 

In simpler terms, Goods and Services Tax is a tax on the supply of goods and services and is applied at each stage of the product or service chain. It is a comprehensive, multi-stage, and destination-based tax, covering all aspects of value addition. Before GST, India had a complex system of indirect taxes. 

Under the GST system, taxes are applied at every point of sale. For intra-state sales, both Central GST and State GST are charged, while inter-state sales are subject to Integrated GST. 

For example, consider a chocolate manufacturer who buys raw materials, produces chocolate, sells them to a warehousing agent, who, in turn, sells to a retailer. Each step adds value to the product, and GST is applied accordingly. 

GST is multi-stage 

It is levied at different points in the supply chain, from raw material purchase to the final sale to the consumer. It captures the value addition that occurs at each stage of production and distribution.   

GST is destination-based 

If goods are manufactured in one state but consumed in another, the tax revenue goes to the consuming state. For instance, if biscuits are made in Maharashtra but sold to consumers in Karnataka, Karnataka receives the tax revenue since GST is levied at the point of consumption. 

Milestones in GST’s journey in India 

The Goods and Services Tax changed India’s indirect tax landscape. Here’s a glimpse into its key milestones:

What are the objectives of GST in India? 

The GST in India was implemented with several key objectives in mind, aiming to bring about comprehensive reform in the taxation system. Here are the main objectives of Goods and Services Tax in India: 

  • Simplify the Tax Structure: 
    • GST amalgamated multiple indirect taxes into a single taxation framework, reducing the intricacies of the previous tax regime. 
  • Create a Unified Market: 
    • GST aims to create a ‘One Nation, One Tax’ system, fostering free movement of goods and services across state borders, promoting economic unity. 
  • Prevent Tax Cascading: 
    • GST allows businesses to claim ITC, ensuring that taxes paid on inputs are offset against the final tax liability. This prevents the tax-on-tax scenario. 
  • Promote Transparency: 
    • GST promotes digitalization and online filing, reducing manual intervention and making the tax system more transparent. It also provides a clear trail of transactions. 
  • Boost Economic Growth: 
    • By simplifying the tax structure, GST aims to reduce compliance costs for businesses, encourage investment, and facilitate economic expansion. 
  • Ensure Fair Taxation: 
    • GST applies the same tax rates across the country for similar goods and services, ensuring equity and fairness in taxation. 
  • Improve Compliance: 
    • GST’s digital infrastructure and streamlined processes aim to make compliance easier for businesses, reducing the scope for tax evasion. 
  • Facilitate Easier Business Operations: 
    • GST simplifies the process of doing business by providing a common platform for tax compliance, making it easier for businesses to operate across different states. 
  • Provide Relief to Consumers: 
    • GST aims to create a more competitive market, preventing the accumulation of taxes at various stages, which could lead to higher prices for consumers. 

What are the advantages of GST in India?   

The Goods and Services Tax implementation in India has brought about several advantages, streamlining the taxation system and contributing to economic growth. Here are some key advantages of Goods and Services Tax in India: 

  • Simplified Tax Structure: 
    • GST replaced a complex and cascading system of multiple indirect taxes with a single, unified tax. This simplification makes it easier for businesses to understand and comply with tax regulations. 
  • Elimination of Cascading Effect: 
    • GST eliminates the cascading effect of taxes, where taxes are charged on taxes. This ensures that businesses only pay taxes on the value addition at each stage of the supply chain. 
  • One Nation, One Tax: 
    • GST promotes the concept of ‘One Nation, One Tax,’ creating a seamless and uniform market across the country. It removes interstate barriers, facilitating the movement of goods and services throughout India. 
  • Reduction in Tax Evasion: 
    • The transparent and technology-driven nature of GST has helped reduce tax evasion. The digitization of processes, including online filing and real-time reporting, enhances accountability and compliance. 
  • Input Tax Credit: 
    • Businesses can claim Input Tax Credit on the taxes paid for inputs, raw materials, and services used in the production process. This prevents the taxation of the same product at multiple stages, promoting efficiency. 
  • Boost to GDP and Economic Growth: 
    • By creating a unified and efficient tax structure, GST has contributed to the growth of the Indian economy. It has enhanced the ease of doing business and attracted investment, fostering economic development. 
  • Sector specific Benefits: 
    • Certain sectors, such as logistics and manufacturing, have experienced positive impacts due to GST. The simplified tax structure has led to cost savings and improved logistics efficiency. 
  • Digital Transformation: 
    • GST has led to the digital transformation of the taxation system. Online filing, e-invoicing, and real-time reporting have not only improved efficiency but also reduced paperwork and manual errors. 
  • Improved Compliance: 
    • The GST regime has encouraged better compliance due to the stringent reporting requirements and penalties for non-compliance. This ensures that businesses fulfill their tax obligations on time. 
  • Consumer Benefits: 
    • While GST impacts businesses, it also benefits consumers by reducing the tax burden on goods and services. Prices of certain goods and services have become more uniform and transparent. 

What are the components of GST? 

In India, Goods and Services Tax is a comprehensive tax that subsumes various indirect taxes. The components of GST include: 

  • Central GST (CGST):
    • This is the tax collected by the Central Government on intra-state supplies of goods and services.
    • The revenue generated through CGST will go to the Central Government. 

  • State GST (SGST):
    • Like CGST, SGST is the tax collected by the State Government on intra-state supplies.
    • The revenue from SGST goes to the respective State Government where the supply originates. 

  • Integrated GST (IGST):
    • IGST is applicable on inter-state supplies of goods and services. It is collected by the Central Government and then shared between the Central and State Governments.
    • The idea is to ensure that the tax revenue is shared appropriately between the states involved in the transaction. 

  • Union Territory GST (UTGST):
    • This is the tax collected by the Central Government on intra-union territory supplies.
    • Union Territories have their own GST legislation, and UTGST is applicable in such cases. 

  • Cess:
    • Cess is an additional tax levied on certain goods and services to fund specific government initiatives.
    • For example, the GST Compensation Cess is applied on certain luxury and sin goods to compensate states for revenue loss during the initial years of GST implementation. 

The combination of CGST, SGST, IGST, UTGST, and Cess constitutes the overall structure of Goods and Services Tax in India. 

For example, imagine a shopkeeper in Karnataka selling goods to another shopkeeper in Maharashtra for INR 50,000. Since it’s an interstate sale, there’s a tax called IGST at 18%, which amounts to INR 9,000. This money will go to the Central Government. 

Now, if the same shopkeeper sells goods to a customer in Karnataka for INR 50,000, the GST rate is 12%. This includes CGST at 6% and SGST at 6%. The total Goods and Services Tax to be collected is INR 6,000. Out of this, INR 3,000 goes to the Central Government, and the remaining INR 3,000 goes to the Gujarat government because the sale is within the state. 

What was the tax law before GST in India? 

Before the implementation of Goods and Services Tax in India, the country had a complex and fragmented system of indirect taxes. The taxation structure included various taxes levied by the central and state governments at different stages of the supply chain. Some of the key taxes that existed before GST are: 

  • Excise Duty:
    • This was a tax imposed on the manufacture of goods within the country. It applied to the production stage and varied based on the type of goods produced. 
  • Value Added Tax (VAT):
    • VAT was a state-level tax imposed on the sale of goods. Each state had its own VAT rates and regulations, leading to a lack of uniformity in the taxation system. 
  • Service Tax:
    • Service tax was a central government tax applied to certain specified services. It covered a range of services provided by businesses, professionals, and service providers. 
  • Central Sales Tax (CST):
    • CST was a tax levied on the sale of goods during inter-state transactions. It was collected by the central government and applied when goods moved from one state to another. 
  • Customs Duty:
    • Customs duty was imposed on the import and export of goods. It was collected by the central government and varied based on the type of goods and the country of origin. 
  • Entry Tax:
    • Some state-imposed entry tax on the movement of goods into their territory. This tax was levied on the entry of goods into a local area for consumption, use, or sale. 

The pre-GST tax system was characterized by a lack of uniformity, complicated compliance procedures, and the cascading effect of taxes (taxes on taxes). The Goods and Services Tax was introduced to simplify this taxation structure, bring about a uniform tax regime across the country, and create a more transparent and efficient tax system. 

How GST helped in price reduction? 

Goods and Services Tax has contributed to price reduction primarily by simplifying the taxation structure, eliminating cascading effects, and fostering a more efficient business environment.  

  • Elimination of Cascading Taxes: 
    • Before Goods and Services Tax, various indirect taxes were levied at different stages of the supply chain, leading to a cascading effect where taxes were imposed on top of taxes. 
    • Goods and Services Tax replaced this complex tax structure, allowing businesses to claim ITC for taxes paid on inputs. This prevents the tax-on-tax scenario, reducing the overall tax burden on the final product. 
  • Uniform Tax Structure: 
    • GST introduced a uniform tax structure, doing away with the varying tax rates across states and territories. This has led to standardization in prices across regions. 
    • Previously, different states had different tax rates, resulting in price variations for the same product in different parts of the country. GST’s uniformity has helped in price stabilization. 
  • Simplified Compliance: 
    • The transition to GST brought about a shift to online filing and compliance, reducing paperwork and administrative overhead for businesses. 
    • This simplified compliance process has lowered the operational costs for businesses, enabling them to pass on the cost savings to consumers in the form of reduced prices. 
  • Efficiency in Logistics: 
    • The removal of check posts and entry taxes at state borders has streamlined the movement of goods across the country. 
    • This reduction in logistical bottlenecks has led to cost savings in transportation and distribution, contributing to overall price reduction. 
  • Boost to Small and Medium Enterprises (SMEs): 
    • GST has simplified the tax structure for small and medium-sized enterprises (SMEs), enabling them to compete more effectively in the market. 
    • With reduced compliance burdens and the ability to claim Input Tax Credit, SMEs can offer products and services at more competitive prices. 
  • Reduced Tax Evasion: 
    • The transparent nature of GST and the digital trail it creates have contributed to a reduction in tax evasion. 
    • With better tax compliance, the government can maintain tax rates at reasonable levels, preventing the need for higher taxes that could lead to increased prices. 

What are the new compliances under Goods and Services Tax? 

The compliance requirements under the Goods and Services Tax in India are subject to changes and updates by the government. New compliance requirements may be introduced, and existing ones may be amended. The latest GST compliance requirements will be updated on the official website of the Goods and Services Tax Network (GSTN)

Some of the common compliance requirements under GST include: 

  • GST Return Filing: 
    • Regular filing of GST returns, such as GSTR-1, GSTR-3B, and others, is based on the nature of the business. 
  • Invoice Matching: 
    • Ensuring that the details of outward supplies in GSTR-1 match with the details of inward supplies in GSTR-2A/2B filed by the recipient. 
  • E-Invoicing: 
    • Implementation of e-invoicing for businesses above a certain turnover threshold, as mandated by the government. 
  • Input Tax Credit Reconciliation: 
    • Regular reconciliation of input tax credit claimed in GSTR-3B with eligible credits as per purchase invoices. 
  • Reverse Charge Mechanism (RCM) Compliance: 
    • Payment of taxes under RCM, where applicable. 
  • Annual GST Audit: 
    • Conducting an annual audit for businesses with a turnover exceeding the prescribed limit. 
  • Filing of Annual Return: 
    • Filing the annual return (GSTR-9) to provide a summary of the annual activities. 
  • Payment of Taxes: 
    • Payment of GST liabilities on time to avoid penalties and interests. 
  • Compliance with GST Rules: 
    • Adhering to specific rules such as GST composition scheme rules, anti-profiteering rules, etc. 


In conclusion, Goods and Services Tax in India redefines the taxation landscape. With its simplified structure, focus on transparency, and commitment to a unified market, GST aims to propel India into a new era of economic growth and development.
