What is GST (Goods and Services Tax) in India?
India's unified indirect tax system since July 2017
GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India. Introduced on July 1, 2017, GST replaced multiple cascading taxes like VAT, service tax, excise duty, and others, creating a unified tax system across the country.
The main objective of GST is to eliminate the "tax on tax" effect and create a common national market. It is a destination-based tax, meaning it is collected at the point of consumption rather than the point of origin. This simplifies taxation for businesses and makes compliance easier.
GST is levied at every stage of the supply chain, but businesses can claim input tax credit for the GST paid on purchases, ensuring that tax is only paid on the value addition at each stage.
How to Calculate GST Using This Calculator
Add or remove GST with step-by-step formulas
Adding GST (Exclusive → Inclusive)
When you have a base price and need to add GST to calculate the final price:
Total Amount = Base Amount × (1 + GST Rate / 100)Example: Base price = ₹10,000, GST = 18%
GST Amount = ₹10,000 × 18 / 100 = ₹1,800
Total Amount = ₹10,000 + ₹1,800 = ₹11,800
Removing GST (Inclusive → Exclusive)
When you have a GST-inclusive price and need to find the base amount:
Base Amount = Total Amount / (1 + GST Rate / 100)Example: Total price = ₹11,800, GST = 18%
Base Amount = ₹11,800 / 1.18 = ₹10,000
GST Amount = ₹11,800 - ₹10,000 = ₹1,800
GST-Inclusive vs GST-Exclusive Prices
When to use base price vs total price in business
GST-Exclusive Price (also called "base price" or "pre-GST price") is the price of goods or services before GST is added. This is typically the cost price or the price at which businesses purchase goods.
GST-Inclusive Price (also called "total price" or "MRP") is the final price that includes GST. This is what consumers pay at retail stores. Most retail prices displayed to end consumers are GST-inclusive.
When to use each:
- Use Add GST when you know the base price and want to calculate the selling price (e.g., pricing products for retail)
- Use Remove GST when you have the final price and need to find the base amount for accounting or tax filing purposes
GST Slabs and Rates in India
Common GST rate tiers and example items
India has a multi-tier GST structure. The most common rate tiers are shown below. Additional cess may apply to certain goods (e.g., luxury cars, tobacco). The applicable rate depends on the HSN/SAC code of the goods or services:
| GST Rate | Common Items |
|---|---|
| 0% | Essential items like fresh vegetables, fruits, milk, bread, eggs, educational services |
| 5% | Household necessities like sugar, tea, coffee, edible oils, coal, medicines |
| 12% | Processed foods, computers, business class air tickets, frozen meat |
| 18% | Most goods and services including IT services, capital goods, industrial intermediaries |
| 28% | Luxury items like automobiles, consumer durables, tobacco products, aerated drinks |
Note: This is a simplified overview. Actual GST rates are determined by HSN (goods) or SAC (services) codes and may change with GST Council notifications. Additional cess may apply on top of these base rates for certain categories. Always verify the latest applicable rate for your specific product or service.
CGST, SGST, and IGST – What's the Difference?
How GST is split for intra-state and inter-state sales
GST in India is divided into three components based on the nature of the transaction:
Intra-State Transactions (Within Same State)
When goods or services are supplied within the same state, GST is split equally between:
- CGST (Central GST): Goes to the Central Government
- SGST (State GST): Goes to the State Government
Example: If GST is 18%, then CGST = 9% and SGST = 9%
Inter-State Transactions (Between Different States)
When goods or services are supplied from one state to another:
- IGST (Integrated GST): The entire GST is collected as IGST by the Central Government, which then settles the state's share with the destination state
Example: If GST is 18%, then IGST = 18% (full amount)
Important: The total GST amount remains the same whether it's CGST + SGST or IGST. The only difference is how the tax revenue is distributed between Central and State governments.
