GST Invoice Generator Free Online — CGST, SGST, IGST Auto-Calculated, No Sign-Up

What is a GST invoice and who needs to issue one?

Under the GST Act 2017, any GST-registered business supplying taxable goods or services must issue a Tax Invoice at the time of supply. The invoice is the primary document for claiming Input Tax Credit (ITC) by the buyer. Without a valid GST invoice, the recipient cannot claim the tax credit they paid — making correct invoicing critical for both parties.

CGST + SGST vs IGST — how to determine which applies

• Intra-state supply — seller's state and place of supply are the same → CGST + SGST applies, each at half the applicable GST rate
• Inter-state supply — seller's state and place of supply are different → IGST applies at the full GST rate

The invoice generator detects this automatically based on the states you enter — no manual calculation needed.

Invoice types supported
