How it works

Intra-state sales split GST equally into CGST + SGST. Inter-state sales use IGST at the full rate — toggle the checkbox to switch.
Each line item can carry its own HSN/SAC code and its own GST rate (0, 5, 12, 18, or 28%) — real invoices frequently mix rates across products, which a single flat rate can't represent.
The preview includes a rate-wise tax summary table (taxable value and tax per GST slab), which is what GST returns actually require.
Amount in words is generated automatically in the Indian numbering system (lakh/crore).
This tool performs the standard calculations only. Always verify HSN/SAC codes, e-invoicing thresholds, and filing rules with your accountant — GST compliance rules vary by turnover and state.
