What is GST in India? Indirect Tax Law Explained Simply
India's taxation system went through a massive transformation when the Goods and Services Tax (GST) was introduced. It replaced a web of indirect taxes with a single, unified structure. GST has not only simplified the tax process for businesses but has also boosted transparency and economic efficiency. From your grocery bill to interstate logistics, GST plays a role in almost every transaction.
What is GST?
GST, or Goods and Services Tax, is an indirect tax imposed on the supply of goods and services. It came into effect on 1st July 2017, replacing multiple indirect taxes, like VAT, excise duty, and service tax. GST is levied at each stage of the supply chain and is designed to allow seamless input tax credit at every level. It’s a destination-based, multi-stage tax system that has brought uniformity to India’s tax structure.
GST is collected by both the central and state governments, depending on the nature of the transaction. On the other hand, State Goods and Services Tax (SGST) applies to intra-state sales, with half the tax going to the state government.
Types of GST in India
Goods and Services Tax (GST) in India is an indirect tax comprising four components - CGST, SGST, UTGST, and IGST - levied based on whether the transaction is within a state, between states, or in a union territory.
- CGST (Central GST) - A tax collected by the Central Government on intra-state transactions of goods and services. It is charged along with SGST, ensuring equal revenue sharing between the Centre and the State.
- SGST (State GST) - Collected by the state government for intra-state sales.
- IGST (Integrated GST) - Charged by the Central Government on inter-state supply of goods and services, including imports. The revenue is later apportioned between the Centre and the destination State.
- UTGST (Union Territory GST) - Applicable in union territories like Delhi and Chandigarh, and collected by the Union government.

How Does GST Work in India?
GST operates through a chain of input and output taxes. When a supplier sells goods or services, they charge GST to the buyer. The buyer can then claim an Input Tax Credit (ITC) for the tax paid if they are also GST registered. This mechanism eliminates the cascading effect of taxes, where previously, taxes were levied on top of other taxes.
For example:
- Manufacturer pays GST on raw materials.
- Wholesaler pays GST on buying finished goods but claims input credit.
- The retailer pays GST again but can claim previous credits.
In the end, tax is only paid on the value added at each stage.

How to Calculate GST?
Understanding GST calculation is essential for both buyers and sellers to ensure accurate pricing and tax compliance. The process involves applying the applicable GST rate to the original price of goods or services.
GST Calculation Formula
GST Amount = (Original Price × GST Rate) ÷ 100
Net Price (price including GST) = Original Price + GST Amount
Alternatively,
Net Price = Original Price × (1 + GST Rate ÷ 100)
Example of GST Calculation
Scenario:
You purchase a product with an original price of ₹10,000 and a GST rate of 18%.
- Calculate GST Amount:
GST Amount = (₹10,000 × 18) ÷ 100
GST Amount = ₹1,800
- Calculate Net Price:
Net Price = ₹10,000 + ₹1,800
Net Price = ₹11,800
Result: You will pay ₹11,800 in total, which includes ₹1,800 GST.

FAQs
Q.1. Can small businesses avoid GST registration?
A. Yes, small businesses can avoid GST registration if their annual turnover is below the prescribed threshold limit under the GST Act. They can also opt for the Composition Scheme, which offers a lower tax rate and simplified compliance. Additionally, certain businesses engaged in exempted goods or services are not required to register.
Q.2. What is Input Tax Credit (ITC), and who can claim it?
A. Input Tax Credit (ITC) allows businesses to claim a credit for the GST paid on purchases against the GST payable on sales. It reduces the tax liability and avoids double taxation. To claim ITC, the business must have valid tax invoices, file GST returns on time, and ensure supplier compliance.
Q.3. How does GST affect the final consumer price of goods?
A. Under GST, the cascading effect of taxes is eliminated, which generally lowers the overall tax burden on goods and services. This can result in reduced final prices for consumers. GST is levied only on the value addition at each stage, making pricing more transparent.
Q.4. What are the penalties for non-compliance with GST laws?
A. Penalties for GST non-compliance include monetary fines, late fees, and interest on delayed filing or payment. For example, failure to register when required can lead to a penalty of 10% of the tax due or ₹10,000, whichever is higher.
Q.5. How is GST different from previous indirect taxes like VAT and service tax?
A. GST replaces multiple indirect taxes such as VAT, service tax, and excise duty with a unified tax regime. This simplifies compliance, reduces tax cascading, and ensures a consistent tax structure across India.
Q.6. What is the role of GST Council?
A. The GST Council is responsible for making key decisions on GST laws, including setting tax rates, exemptions, thresholds, and procedural rules. It ensures uniform implementation of GST across states and promotes cooperative federalism.
