GST Invoice Generator
Create a clean, GST-compliant tax invoice. Add GSTIN, HSN/SAC codes, and place of supply - the tool splits tax into CGST & SGST for intra-state sales or applies IGST for inter-state sales automatically. You can review and edit everything before download.
GST rules can change. This tool helps format invoices but does not replace tax or legal advice. Please verify important invoices with a qualified professional.
GST invoice basics for India
Under India's Goods and Services Tax, a registered business must issue a tax invoice for taxable supplies. The invoice is the primary document a buyer uses to claim input tax credit, so the details need to be accurate and complete.
Fields a GST invoice should include
- Supplier name, address, and GSTIN
- A consecutive invoice number and the invoice date
- Recipient name, address, and GSTIN (if registered)
- Place of supply and the state code
- HSN/SAC code for each item or service
- Description, quantity, rate, and taxable value
- GST rate and amount - CGST & SGST, or IGST
- Whether reverse charge applies
- Signature of the supplier or an authorised signatory
How the CGST / SGST / IGST split works
GST is a destination-based tax. When the supplier and the place of supply are in the same state, the total GST is divided equally into CGST (central) and SGST (state). When they are in different states, a single IGST is charged at the full rate. Since the September 2025 GST reform, the main rates are 0% (exempt), 5%, and 18%, with a 40% rate on select luxury and sin goods; you can set a different rate for each line item.
Reverse charge
For certain supplies, the recipient - not the supplier - is liable to pay GST. When this applies, tick the reverse charge box so it is clearly noted on the invoice.
Before downloading a GST invoice
GST invoices are used by buyers for input tax credit, so small field errors can create real follow-up work.
- GSTINs are correct
Check supplier GSTIN and recipient GSTIN before sending the PDF.
- Place of supply is set
This decides whether the invoice shows CGST + SGST or IGST.
- HSN/SAC is reviewed
Do not guess classification codes; confirm the code for the goods or service.
- Reverse charge is marked if needed
If the recipient accounts for GST, make that treatment visible on the invoice.
