The Goods and Services Tax (GST) is a unified indirect tax system that was implemented in India on 1st July 2017. It replaced multiple indirect taxes levied by the Central and State governments and aimed to bring uniformity in the taxation of goods and services.
The Implementation Mechanism of GST involves a well-defined legal, administrative, and technological framework. Let’s explore its key components.
Constitutional Framework
a) Constitutional Amendment
-
The 101st Constitutional Amendment Act, 2016 empowered both the Centre and States to levy GST.
-
It introduced Article 246A, giving concurrent powers to both Parliament and State Legislatures.
-
Article 279A provided for the formation of the GST Council.
Types of GST
To ensure a shared revenue structure, GST in India is divided into the following components:
| Type of GST | Levied By | Applies To |
|---|---|---|
| CGST | Central Government | Intra-state supply of goods and services |
| SGST | State Government | Intra-state supply of goods and services |
| UTGST | Union Territory Govt. | Intra-UT supply in union territories |
| IGST | Central Government | Inter-state and international supplies |
Example:
If a product is sold within Maharashtra, both CGST and SGST are levied. If sold from Maharashtra to Gujarat, IGST is levied.
Role of the GST Council
The GST Council is the apex decision-making body for GST matters.
a) Composition:
-
Chairperson: Union Finance Minister
-
Members: State Finance/Taxation Ministers
b) Key Functions:
-
Recommend tax rates and exemptions
-
Decide threshold limits for registration
-
Frame model GST laws and rules
The council plays a critical role in harmonizing GST laws across India.
Registration Process
Businesses must register under GST if they meet specified turnover limits.
a) Threshold Limits:
-
₹40 lakhs for goods (normal states)
-
₹20 lakhs for services
-
Lower limits for special category states
b) Procedure:
-
Apply online via https://www.gst.gov.in
-
Upload required documents (PAN, Aadhaar, business proof)
-
Receive GSTIN (Goods and Services Tax Identification Number)
GST Compliance Structure
a) Returns Filing:
-
Monthly, quarterly, and annual returns depending on the taxpayer category
-
Common forms: GSTR-1, GSTR-3B, GSTR-9
b) Input Tax Credit (ITC):
Businesses can claim credit for GST paid on purchases to reduce their output tax liability.
Example:
If GST paid on inputs = ₹10,000 and GST on sales = ₹15,000, then payable tax = ₹5,000.
c) Tax Payment:
GST is paid online through the GST portal using:
-
Internet banking
-
Credit/debit card
-
Challan generation
Role of Technology – GSTN
a) GST Network (GSTN):
A not-for-profit organization that provides the IT infrastructure for GST implementation.
b) Key Features:
-
Registration portal
-
Invoice matching
-
Return filing interface
-
Input tax credit verification
GSTN ensures transparency, real-time tracking, and data analytics for tax compliance.
Anti-Profiteering Mechanism
The National Anti-Profiteering Authority (NAA) was established to:
-
Ensure that businesses pass on the benefits of tax rate reduction or input tax credit to consumers.
-
Take action against those increasing prices unjustifiably post-GST.
Compliance Rating System
The GST system also plans to introduce a compliance rating to assess the behaviour of taxpayers based on:
-
Timely filing
-
Payment of taxes
-
Transparency
A good compliance score may offer faster refunds and fewer audits.
Conclusion
The implementation mechanism of GST is a combination of constitutional amendments, legal statutes, administrative structures, and digital systems. The dual GST model, governed by the GST Council, supported by the GST Network, and regulated through standardized registration, return filing, and ITC procedures, ensures smooth and uniform tax administration across India.
