GST (Goods and Services Tax) is India's comprehensive indirect tax reform that replaced multiple cascading taxes like Central Excise Duty, Service Tax, VAT, Entertainment Tax, and others. Implemented on July 1, 2017, GST is a destination-based, multi-stage tax levied on every value addition in the supply chain.
What is GST?
GST is a single tax on the supply of goods and services from the manufacturer to the consumer. It is collected at each stage of the supply chain, but the end consumer bears only the GST charged by the last dealer. This eliminates the cascading effect of tax-on-tax that existed under the previous system.
For example, under the old system, a manufacturer paid excise duty on raw materials, then VAT on the finished product, and the consumer also paid service tax on certain services. With GST, all these taxes are unified, and businesses can claim credit for taxes paid on inputs, ensuring tax is only paid on the value addition at each stage.
Types of GST: CGST, SGST, IGST
GST in India operates under a dual model where both the Central and State governments levy tax on the same base. The three components are:
- CGST (Central GST): Collected by the Central Government on intra-state supplies. The revenue goes to the central government.
- SGST (State GST): Collected by the State Government on intra-state supplies. The revenue goes to the state where the goods/services are consumed.
- IGST (Integrated GST): Collected by the Central Government on inter-state supplies and imports. The revenue is shared between the center and the destination state.
For intra-state transactions (within the same state), CGST and SGST are charged equally. For example, if GST rate is 18%, CGST = 9% and SGST = 9%. For inter-state transactions, IGST is charged at the full rate (e.g., 18% IGST).
GST Rate Structure
India has a multi-tier GST rate structure with four primary slabs:
| Rate | Category | Examples |
|---|---|---|
| 0% | Essential | Fresh fruits, vegetables, milk, eggs, bread, salt, educational services, healthcare |
| 5% | Necessity | Packaged food, footwear below ₹500, economy flights, rail tickets, sugar, tea |
| 12% | Standard | Processed food, butter, ghee, business class flights, cell phones, umbrellas |
| 18% | Standard Plus | Capital goods, IT services, restaurants (AC), telecom, financial services, most goods |
| 28% | Luxury | Cars, tobacco, aerated drinks, luxury hotels (₹7,500+), cinema, cement |
Additionally, there are special rates for certain items like gold (3%), rough precious stones (0.25%), and some other categories. The GST Council periodically reviews and revises these rates.
GST Registration
Businesses must register for GST if their aggregate turnover exceeds the prescribed threshold:
- ₹40 lakh for goods suppliers (₹20 lakh for special category states)
- ₹20 lakh for service providers (₹10 lakh for special category states)
- ₹40 lakh for e-commerce sellers (mandatory regardless of turnover)
Registration is done online through the GST portal (gst.gov.in). You need a PAN, Aadhaar, business address proof, bank account details, and digital signature. Once registered, you receive a 15-digit GSTIN (GST Identification Number).
GST Returns Filing
GST returns are filed online and the frequency depends on your turnover and scheme:
| Return | Frequency | Due Date | Who Files |
|---|---|---|---|
| GSTR-1 | Monthly/Quarterly | 11th of next month | Outward supplies |
| GSTR-3B | Monthly/Quarterly | 20th of next month | Summary return |
| GSTR-9 | Annual | 31st December | Annual return |
| GSTR-4 | Annual | 30th April | Composition dealers |
Input Tax Credit (ITC)
Input Tax Credit is the core benefit of GST. It allows businesses to reduce the tax paid on inputs (purchases) from the tax collected on outputs (sales). This eliminates the cascading effect of taxes.
For example, if you collect ₹1,800 as GST on sales (output) and paid ₹900 as GST on purchases (input), you only need to deposit ₹900 to the government. To claim ITC, you must have a valid tax invoice, the goods/services must be used for business purposes, and the supplier must have filed their returns.
Composition Scheme
The Composition Scheme is a simplified scheme for small businesses with turnover up to ₹1.5 crore (₹75 lakh for special states). Under this scheme:
- Pay a fixed percentage of turnover as tax (1% for manufacturers, 5% for restaurants, 6% for services)
- File quarterly returns instead of monthly
- Cannot collect tax from customers or claim input tax credit
- Cannot make inter-state supplies
