What is a GST invoice?
A GST invoice (tax invoice) is the document a registered business issues for the supply of goods or services. Under the GST law it must show the supplier and recipient details, GSTIN, invoice number and date, a description of each item with its HSN/SAC code, the taxable value, and the tax charged — CGST and SGST for sales within the same state, or IGST for inter-state sales.
CGST + SGST vs IGST — how it works
When the supplier's state and the place of supply are the same, the GST is split equally into Central GST (CGST) and State GST (SGST). For example, an 18% rate becomes 9% CGST + 9% SGST. When the supply is inter-state, a single Integrated GST (IGST) at the full rate is applied instead. This tool decides automatically based on the states you select, so you never have to calculate it by hand.
