A Complete Guide to GST in India: Meaning, Types, Registration, Returns & Benefits
The Goods and Services Tax (GST) is one of the most significant tax reforms implemented in India. Introduced on 1st July 2017, GST replaced multiple indirect taxes like VAT, Service Tax, Excise Duty, and more — creating one unified tax system across the country.
Whether you are a business owner, freelancer, manufacturer, trader, or service provider, understanding GST is crucial for smooth operations and compliance.
This blog explains GST in a comprehensive yet simple manner.
What is GST?
GST stands for Goods and Services Tax, a destination-based indirect tax applied to the supply of goods and services. It is collected at every stage of the supply chain but ultimately borne by the final consumer.
GST follows a multi-stage system, meaning tax is applied at each step of production/distribution, but businesses can claim Input Tax Credit (ITC), preventing tax-on-tax.
Key Features of GST
✔ One Nation, One Tax
Replaces multiple state and central taxes.
✔ Input Tax Credit (ITC)
Businesses can claim credit for tax paid on purchases, reducing overall tax burden.
✔ Online and Transparent
Registration, returns, and payments are done completely online on the GST portal.
✔ Destination-Based Tax
Tax is collected where goods/services are consumed.
✔ Reduces Cascading Effect
No more double taxation on goods and services.
Types of GST in India
GST is divided into four major categories to simplify tax sharing between Centre and States:
1. CGST – Central Goods and Services Tax
Collected by the Central Government for intra-state (within the same state) transactions.
2. SGST – State Goods and Services Tax
Collected by the State Government for intra-state transactions.
3. IGST – Integrated Goods and Services Tax
Applied to inter-state transactions (between different states).
4. UTGST – Union Territory Goods and Services Tax
Applicable when goods/services are supplied within Union Territories.
Who Should Register Under GST?
GST registration is mandatory for:
✔ Businesses with turnover above ₹40 lakh
(₹20 lakh for services)
✔ E-commerce sellers and aggregators
✔ Businesses involved in inter-state supply
✔ Casual taxable persons
✔ Reverse charge mechanism (RCM) taxpayers
✔ Input Service Distributors (ISD)
Even if you don’t fall under mandatory criteria, voluntary registration can help in availing benefits like ITC and better business credibility.
