How GST Invoicing Works in India

Under the Goods and Services Tax (GST) framework in India, registered businesses must issue a compliant Tax Invoice indicating whether the transaction is intra-state or inter-state.

Intra-State Supply

CGST + SGST (Same State)

When the supplier and the place of supply are in the same Indian state (e.g. Karnataka to Karnataka), GST is split equally into Central GST (CGST) and State GST (SGST). For example, an 18% tax is calculated as 9% CGST and 9% SGST.

Inter-State Supply

IGST (Different States)

When goods or services are supplied across state borders (e.g. Maharashtra to Delhi), Integrated GST (IGST) applies as a single combined tax rate without splitting.
