Understanding GST: Overview and Structure
The Goods and Services Tax (GST) is India's most comprehensive tax reform, replacing multiple indirect taxes with a unified taxation system. Implemented on July 1, 2017, GST has fundamentally changed how businesses handle taxation, requiring new compliance processes and documentation standards.
GST Structure and Components
GST operates on a dual model with both Central and State components:
CGST (Central GST)
Collected by the Central Government on intra-state transactions
SGST (State GST)
Collected by State Governments on intra-state transactions
IGST (Integrated GST)
Applied on inter-state transactions and imports
UTGST (UT GST)
Applied in Union Territories without legislature
GST Tax Rates
| Tax Slab | Items/Services | Examples |
|---|---|---|
| 0% | Essential commodities | Rice, wheat, fresh fruits, vegetables |
| 5% | Necessity items | Sugar, tea, coffee, medicines |
| 12% | Standard rate items | Computers, processed foods |
| 18% | Most goods and services | Soaps, toothpaste, IT services |
| 28% | Luxury and sin goods | Cars, tobacco, luxury items |
Key Principle: GST follows the principle of "One Nation, One Tax" with input tax credit availability across the supply chain, making it a destination-based consumption tax.
