About the GST Invoice Generator
A GST invoice, or tax invoice, is the document a registered supplier issues for a taxable supply of goods or services. It records what was sold, the taxable value, and the GST charged, split into CGST and SGST for sales within a state or IGST for sales across states. This free generator calculates the tax for each line item automatically and produces a clean, print-ready invoice you can download as a PDF.

Fields a GST invoice must contain
- Supplier name, address and GSTIN
- A consecutive, unique invoice number and the date of issue
- Recipient name, address and GSTIN (for B2B supplies)

Intra-state versus inter-state supply
The place of supply decides the type of GST. For an intra-state supply, the tax is shared equally between the Centre (CGST) and the State (SGST). For an inter-state supply, a single Integrated GST (IGST) applies. Selecting the supply type in the form switches the invoice between the two layouts automatically.

Frequently Asked Questions
A GST tax invoice should carry the supplier name, address and GSTIN, a unique invoice number and date, the recipient details, a description of goods or services with HSN or SAC codes, the taxable value, the GST rate and amount (split into CGST and SGST for intra-state supply or IGST for inter-state supply), and the total. This generator includes all of these fields.
When the supplier and the place of supply are in the same state (intra-state), the GST is split equally into CGST and SGST. When they are in different states (inter-state), a single IGST is charged at the full rate. Choose the supply type in the form and the tax columns adjust automatically.
HSN codes for goods and SAC codes for services are required based on your turnover. Businesses with turnover above the prescribed threshold must mention them on B2B invoices. It is good practice to include them on every invoice, so the form provides a column for each line item.
This tool is built for GST tax invoices with tax calculation. If you do not need GST, use the simple Invoice Generator instead, which produces a clean invoice without tax columns.
