Overview — CGST, SGST & IGST

Under India's GST framework, tax is split between the Centre and States. For intra-state supplies (seller and buyer in the same state), the GST is split equally into CGST (Central) and SGST/UTGST (State/UT). For inter-state supplies (seller and buyer in different states), the full GST is levied as IGST (Integrated GST). The Place of Supply determines which rule applies — it is typically the buyer's state. Every GST invoice must show state codes (e.g., 27 for Maharashtra, 36 for Telangana), GSTIN, HSN/SAC codes, and itemised tax breakdowns.

Frequently Asked Questions

CGST (Central GST) and SGST (State GST) are charged together for intra-state supplies — each gets half the total GST rate. IGST (Integrated GST) is charged on inter-state supplies — collected by the Centre and then shared with the destination state. E.g., for an 18% GST intra-state: CGST = 9% + SGST = 9%. Inter-state: IGST = 18%.
For goods, the Place of Supply is typically where the goods are delivered (buyer's state). For services, it is usually the location of the recipient. If seller's state = Place of Supply state → CGST+SGST. If different → IGST.
Each Indian state and UT has a 2-digit GST code (01–38). For example, Maharashtra = 27, Telangana = 36, Delhi = 07. The first 2 digits of any GSTIN are the state code. This tool shows state codes automatically based on your state selection.
HSN (Harmonised System of Nomenclature) codes classify goods, while SAC (Services Accounting Code) codes classify services. Businesses with turnover above ₹5 crore must use 6-digit HSN codes. Below ₹5 crore (but above ₹1.5 crore) need 4-digit codes. This tool's HSN-wise summary table is compatible with GSTR-1 filing.
The invoice format meets GST Act requirements including GSTIN, invoice number, date, HSN codes, place of supply, state codes, and tax breakdowns. Ensure all mandatory fields are correctly filled. For complex transactions (e-invoicing mandate, export), consult a CA or use official IRP portals.
