CGST, SGST and IGST — Which Applies to Your GST Bill?
Understanding the difference is critical for issuing a correct GST tax invoice. CGST (Central GST) + SGST (State GST) apply when both seller and buyer are in the same state — called an intra-state transaction. Each is levied at exactly half the applicable GST rate. For example, on a ₹10,000 item at 18% GST, CGST = ₹900 and SGST = ₹900.
IGST (Integrated GST) applies when the seller and buyer are in different states — called an inter-state transaction. It is charged at the full GST rate. On the same ₹10,000 item at 18% GST, IGST = ₹1,800. Our free GST bill maker reads the first two digits of both GSTINs to auto-detect and switch between these modes automatically.
