What is GST (Goods and Services Tax)?

GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India. It replaced multiple taxes like VAT, service tax, excise duty and others when it was introduced on 1 July 2017. GST is a destination-based tax collected at every stage of the supply chain, with input tax credit available to avoid the cascading effect of taxes.

GST Slabs in India

India follows a four-tier GST structure: 5% (essential items like packaged food, footwear below Rs 1,000), 12% (processed food, computers, bicycles), 18% (most goods and services including IT services, restaurants), and 28% (luxury goods, cars, aerated drinks). Some items like fresh fruits, vegetables and milk are exempt from GST (0%).

For intra-state transactions, GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state transactions, IGST (Integrated GST) is charged at the full rate. The total tax amount remains the same in both cases.

Frequently Asked Questions

How do I calculate GST-inclusive price from a GST-exclusive amount?

To add GST: Total = Base Amount + (Base Amount x GST Rate / 100). For example, if the base price is Rs 1,000 and GST is 18%, then GST amount = Rs 180 and total = Rs 1,180.

How do I find the base price from a GST-inclusive amount?

To remove GST: Base Amount = GST-inclusive Amount / (1 + GST Rate / 100). For example, if the total is Rs 1,180 at 18% GST, the base price = 1180 / 1.18 = Rs 1,000.

What is the difference between CGST, SGST and IGST?

CGST (Central GST) and SGST (State GST) are charged on intra-state (within the same state) transactions, each at half the total GST rate. IGST (Integrated GST) is charged on inter-state transactions at the full rate. The total tax burden on the buyer is the same in both cases.
