Introduction
The Goods and Services Tax (GST) is India’s unified indirect tax, implemented nationwide on 1st July 2017. It replaced a complex mix of earlier state and central taxes—like VAT, excise duty, and service tax—with a comprehensive, destination-based system. Levied on the supply of goods and services, GST simplifies compliance, removes the cascading effect of taxes, and supports economic growth.
What is GST?
GST is a multi-stage, destination-based tax imposed at each value addition stage in a product or service supply chain. At every transaction, it’s charged only on the incremental value added, ensuring transparent pricing and enabling seamless input tax credit (ITC) for businesses.
Origins and Key Milestones
Year | Milestone |
---|---|
2000 | Committee set up to draft GST law |

Objectives of GST
- Unified Indirect Tax System – Merges multiple central and state taxes under one structure.
- Removes Cascading Effect – Input tax credit prevents double taxation.
- Minimises Tax Evasion – Technology-driven filings, e-invoicing, and transparent tracking.
- Wider Tax Base – Brings more businesses into the formal system.
- Boosts Ease of Doing Business – Fully electronic registration, filing, and refunds.
How GST Works: Example
A biscuit manufacturer buys raw materials like flour and sugar, bakes biscuits, and sells them to a warehouse. The warehouse adds packing value and sells them to retailers, who finally sell to consumers. GST is levied at each stage only on the value added, with ITC available, reducing the final cost for the customer.

Comparison: Pre-GST vs GST
Stage | Cost (₹) | Tax Rate | Pre-GST Tax | GST (Paid by Stage) |
---|---|---|---|---|
Manufacturer | 1,000 | 10% | 100 | 100 |
After Warehousing | 1,300 | 10% | 140 | 30 |
After Retail Packing | 1,800 | 10% | 204 | 50 |
Total | 444 | 180 |
Result: GST reduces the effective total tax burden.
