Understanding the Types of GST in India
Depending on whether you are selling within your state or to another state, different GST components apply:
CGST & SGST
Central & State GST: Applied on intra-state (within same state) sales. The total tax is split 50:50 between the Center and the State.
IGST
Integrated GST: Applied on inter-state (between different states) transactions and imports. The entire tax goes to the Central Government.
UTGST
Union Territory GST: Applied on transactions within Union Territories like Andaman & Nicobar or Lakshadweep, replacing SGST.
Common GST Tax Slabs in India
The GST Council has categorized goods and services into four major tax slabs. Knowing your slab is essential for accurate invoicing:
| Slab | Category | Example Items |
|---|---|---|
| 5% | Essentials | Sugar, Spices, Tea, Coal, Medicines |
| 12% | Standard | Butter, Ghee, Mobile Phones, Bio-gas |
| 18% | Most Services | IT Services, Restaurants, Steel, Hair Oil |
| 28% | Luxury/Sin | Cars, Tobacco, Aerated Drinks, High-end ACs |
GST Compliance Tips for Small Businesses
If you're a freelancer or a small business owner in India, follow these GST best practices:
- HSN/SAC Codes: Always mention the 4 or 6-digit Harmonized System of Nomenclature (HSN) code for goods or Services Accounting Code (SAC) for services on your invoice.
- Input Tax Credit (ITC): You can reduce the GST you pay on sales by the amount of GST you covered on your business purchases. Keep every purchase bill safe!
- Composition Scheme: If your turnover is below ₹1.5 Crore, consider the Composition Scheme for lower tax rates and simpler compliance.
- Reverse Charge Mechanism (RCM): In some cases, the buyer is responsible for paying GST instead of the seller. Ensure you understand if RCM applies to your business.
Frequently Asked Questions - GST Implementation
