The Goods and Services Tax (GST), launched on 1 July 2017, is one of the biggest tax reforms in India’s history. It unified multiple indirect taxes under a single system, eliminating the complex web of excise, VAT, and service taxes.
1️⃣ Why GST Was Introduced
Before GST, India’s tax structure had multiple cascading taxes:
- Central Excise, Service Tax (Centre)
- VAT, Entry Tax, Octroi (State)
- Different rates in every state
This created confusion and “tax on tax”, leading to inefficiency.
GST replaced them with “One Nation, One Tax”, ensuring a seamless flow of goods and services across India.
2️⃣ What Exactly is GST?
GST is a destination-based indirect tax levied on the supply of goods and services.
It is collected at every stage but credited back through an Input Tax Credit (ITC) system — ensuring no double taxation.
Structure of GST
| Type | Levied By | Example |
|---|---|---|
| CGST | Central Govt | Central share of tax |
| SGST | State Govt | State share of tax |
| IGST | Centre (Inter-State) | Tax on interstate supply |
3️⃣ Constitutional & Legal Basis
- Governed by Article 246A and 122nd Constitutional Amendment Act, 2016.
- Administered by CBIC (Central Board of Indirect Taxes and Customs).
- Policy decisions made by the GST Council chaired by the Union Finance Minister.
4️⃣ Benefits of GST
| For Business | For Consumers | For Government |
|---|---|---|
| Reduced compliance | Lower prices | Higher revenue transparency |
| Seamless ITC flow | No double taxation | Wider tax base |
