CGST, SGST and IGST on One Invoice

Which GST lines appear depends on where the goods or services are supplied. A sale inside one state carries central and state GST, each half of the rate. A sale to another state carries a single integrated GST line at the full rate. The tool does not decide this for you, so you choose the lines that match your sale.

You can add up to 20 taxes and choose which lines each one applies to, so mixed invoices work too, for example one item at 18% and another at 5%. Prices can be entered with GST included or added on top.

What a GST Tax Invoice Normally Shows

A GST-registered business issuing a tax invoice generally includes the details below. Rules differ by business type and turnover, so confirm your own requirements with your accountant or the GST portal.

• Supplier details your name, address and GSTIN, which the tool places in the header.
• Invoice number and date a sequential number of up to 16 characters. The tool’s default format, such as INV-2026-0001, fits.
• Recipient details the client’s name and address, plus their GSTIN when they are registered.
• Item details a description, quantity and taxable value for each line. Type the HSN or SAC code into the description, for example “Steel brackets, HSN 7326”.
• Tax rate and amount each of CGST, SGST or IGST with its rate and amount, as separate lines.
• Place of supply the state of supply, which you can add under Notes & terms.
• Signature draw or upload one in the design step, with the signatory’s name and title.

If you are not registered for GST, or you pay tax under the composition scheme, you do not charge GST on your invoices and you issue a bill of supply instead of a tax invoice. Turn off the GST-registered option under Where is your business?, and rename the document title in the details step.

GST Invoice Format in Excel and PDF

Press Excel on the result screen to get a workbook named like Invoice-INV-2026-0001.xlsx. Its first sheet is laid out like the invoice, with your GSTIN, the items, each GST line and the total. The second sheet lists one plain row per item, so it pastes straight into your bookkeeping sheet. Amounts are real numbers with a currency format, not text, so you can add them up and filter them.

The PDF uses real, selectable text and carries the ₹ symbol, so it prints and shares cleanly. If the font cannot load on a slow connection, the tool falls back to the currency code INR and tells you so.

What This Tool Does Not Do

This is an invoice maker, not GST compliance software. It does not generate an e-invoice reference number (IRN) or e-way bill, file GST returns, look up HSN or SAC codes, or work out the place of supply for you. If your turnover requires e-invoicing through the government portal, use that system for the invoice itself and check the current rules with your accountant.
