Goods and Services Tax (GST) is India's biggest tax reform since independence. Introduced on July 1, 2017, it unified 17 indirect taxes into one. Understanding GST is essential for every business operating in India — and similar consumption taxes exist worldwide (VAT, SST, GST in Australia).
Before GST: Excise Duty + VAT + Service Tax + CST + Entry Tax + Luxury Tax + Entertainment Tax + Octroi = cascading taxes, complicated compliance, and tax-on-tax effects.
After GST: One Nation, One Tax. A single tax on supply of goods and services, with seamless Input Tax Credit across the supply chain.
Tax is collected by the state where goods are consumed, not where they are produced. Benefits consuming states.
GST is levied at every stage of the supply chain — manufacturing, wholesale, retail — but credit eliminates cascading.
Suppliers must upload invoices. Buyers can only claim ITC if their supplier has filed. This creates compliance incentive.
Collected by Central Government on intra-state supplies. Rate = half of total GST rate.
Collected by State Government on intra-state supplies. Rate = half of total GST rate.
Collected by Central Government on inter-state supplies and imports. Rate = full GST rate.
| Rate | Category | Examples |
|---|---|---|
| 0% | Essential / Exempt | Fresh milk, vegetables, cereals, education, healthcare |
| 5% | Basic Necessities | Packaged food, economy travel, fertilizers, newspapers |
| 12% | Standard (Lower) | Processed food, business class travel, sewing machines, cell phones |
| 18% | Standard (Most Common) | Most goods & services, restaurants, IT services, financial services |
| 28% | Luxury / Demerit | Cars, tobacco, aerated drinks, luxury hotels, cement, ACs |
ITC is what makes GST different from old taxes. It eliminates the cascading effect (tax on tax) by allowing you to set off GST paid on purchases against GST collected on sales.
GST replaced 17 indirect taxes with one unified tax — simplifying compliance and eliminating tax cascading
Intra-state = CGST + SGST (split equally). Inter-state = IGST (full rate, distributed by central government)
Five rate slabs: 0%, 5%, 12%, 18%, 28%. Most services and manufactured goods fall under 18%
Input Tax Credit (ITC) is the core benefit — claim GST paid on purchases against GST collected on sales
