How is GST Calculated?
GST (Goods and Services Tax) replaced all indirect taxes in India from July 2017. The rate depends on the category of goods or services — 5%, 12%, 18%, or 28%.
To ADD GST:
GST Amount = Base Amount × GST% / 100
Total = Base Amount + GST Amount
To REMOVE GST (from MRP/inclusive price):
Base Amount = MRP × 100 / (100 + GST%)
GST Amount = MRP - Base Amount
CGST, SGST vs IGST
For sales within the same state (intra-state), the GST is split equally — half goes to Centre (CGST) and half to the State (SGST). For sales across states (inter-state), the full GST is charged as IGST, which is later distributed between Centre and destination state.
Frequently Asked Questions
What are the GST slabs in India? ⌄
GST has four main slabs: 5% (essential goods, restaurants), 12% (processed food, computers), 18% (most goods and services, AC restaurants), and 28% (luxury goods, cars, tobacco). Some items like fresh food and healthcare are at 0%.
What is the difference between CGST, SGST, and IGST? ⌄
For intra-state sales, GST is split equally into CGST (Central GST) and SGST (State GST). For inter-state sales, IGST (Integrated GST) is charged at the full rate, which is later divided between centre and state.
How do I calculate GST on an MRP price? ⌄
To reverse-calculate GST from an MRP (inclusive price): GST Amount = MRP − (MRP × 100 / (100 + GST%)). For example, MRP ₹118 at 18% GST → GST = 118 − (118 × 100/118) = ₹18.
Who needs to register for GST? ⌄
Any business with annual turnover above ₹40 lakh (₹20 lakh for services, ₹10 lakh for special category states) must register for GST. E-commerce sellers and inter-state suppliers must register regardless of turnover.
What is a composite GST rate? ⌄
Small businesses with turnover below ₹1.5 crore can opt for the Composition Scheme, paying a flat GST rate (1% for traders, 5% for restaurants, 6% for services) instead of the regular slab rates. They cannot claim ITC.
