Under India's Dual GST model, taxes are collected by both the Central and State Governments. Intra-state transactions (within the same state) are split equally into CGST and SGST, while inter-state transactions are subject to IGST.
GST rates in India are categorized under five standard slabs: 0% (essential foods, books), 5% (transport, packaged food items), 12% (processed foods, apparel), 18% (most services, capital goods, IT), and 28% (luxury items, cement, automotive).
💡 Claiming Input Tax Credit (ITC)
Always match vendor GSTIN and invoice dates against your GSTR-2B before claiming ITC to avoid interest notices under Section 50.
💡 Reverse GST Calculation Formula
To find base price from gross MRP: Base = Gross / (1 + Rate / 100). The tax amount is simply Gross minus Base.
