India's Goods and Services Tax (GST) applies to most goods and services sold in the country. It replaced a complex web of central and state taxes with a unified structure, but the multiple slab rates (0%, 5%, 12%, 18%, 28%) still confuse a lot of people.
GST Slabs in India — What Rate Applies to What?
- 0% GST: Essential food items, fresh vegetables, milk, eggs
- 5% GST: Packaged food, economy class air travel, small restaurants
- 12% GST: Processed food, business class travel, mobile phones under ₹12,00,000
- 18% GST: Most services (telecom, banking, IT), restaurants in hotels, majority of manufactured goods
- 28% GST: Luxury items, automobiles, tobacco, aerated drinks
How to Add GST to a Base Price
Formula: Final Price = Base Price × (1 + GST Rate / 100). For example, a product priced at ₹1,000 with 18% GST: ₹1,000 × 1.18 = ₹1,180.
How to Remove GST from a GST-Inclusive Price (Reverse GST)
Formula: Base Price = GST-Inclusive Price / (1 + GST Rate / 100). For example, you paid ₹1,180 including 18% GST. Base price = ₹1,180 / 1.18 = ₹1,000. GST component = ₹180.
CGST and SGST Breakdown
For intra-state transactions, GST is split equally into CGST (Central GST) and SGST (State GST). So 18% GST = 9% CGST + 9% SGST. For inter-state transactions, it's IGST at the full rate.
Frequently Asked Questions
How do I calculate 18% GST on an amount?
Multiply the base amount by 0.18 to get the GST amount. Add it to the base price for the final GST-inclusive price. Example: ₹5,000 × 0.18 = ₹900 GST. Final price = ₹5,900.
What is reverse GST calculation?
Reverse GST finds the original price before GST from a GST-inclusive amount. Formula: Base Price = Total Price ÷ (1 + GST%/100).
Is GST included in restaurant bills in India?
Yes. Restaurants charge 5% GST (without input tax credit) or 18% GST if operating in a hotel with room tariff above ₹7,500.
