Open GST Invoice GeneratorWhat this GST invoice template includes
A GST tax invoice has to carry more than a normal bill. Beyond your business header and an itemised table, it must identify both parties by GSTIN, classify each line with an HSN or SAC code, and show the tax broken out correctly based on where the supply takes place. This template lays out every mandatory field so a registered buyer can claim input tax credit without chasing you for corrections.
Mandatory fields on a GST tax invoice
- Supplier name, address, and GSTIN
- A consecutive, unique invoice number and the invoice date
- Recipient name, address, and GSTIN (where the buyer is registered)
- Place of supply, and the state code for inter-state transactions
- HSN code for goods or SAC code for services, per line item
- Taxable value of each item after any discount
- Rate and amount of CGST + SGST, or IGST for inter-state supply
- Whether tax is payable on a reverse-charge basis
- Signature or digital signature of the supplier
Intra-state versus inter-state tax
The single most common GST mistake is applying the wrong tax heads. The rule turns on the place of supply, not on where you happen to be sitting. If the place of supply is in the same state as the supplier, the supply is intra-state and you split the total GST into equal CGST and SGST portions. If the place of supply is in a different state, it is an inter-state supply and you charge a single IGST at the combined rate.
Example use case
A consultancy registered in Maharashtra raises two invoices on the same day. The first is to a client in Mumbai for ₹1,00,000 of taxable services at 18%: because the place of supply is within Maharashtra, the invoice shows ₹9,000 CGST plus ₹9,000 SGST. The second is to a client in Bengaluru for the same ₹1,00,000 at 18%: now the place of supply is Karnataka, so the invoice shows a single ₹18,000 IGST line instead. Same rate, same amount - only the tax heads change with the destination.
Common mistakes to avoid
- Charging CGST + SGST on an inter-state supply (or IGST on a local one)
- Leaving off the recipient GSTIN so the buyer cannot claim input credit
- Omitting or guessing HSN/SAC codes for your goods and services
- Skipping the place of supply, which decides the tax treatment
- Forgetting to flag invoices that fall under reverse charge
- Breaking the consecutive numbering of your invoice series

Frequently asked questions
What is an HSN or SAC code and do I need one? +
HSN (Harmonised System of Nomenclature) codes classify goods, while SAC (Services Accounting Code) codes classify services. A GST tax invoice should carry the relevant HSN/SAC for each line item; the number of digits required depends on your turnover, so check the current threshold that applies to you.
When do I charge CGST + SGST versus IGST? +
It depends on the place of supply. For an intra-state supply (supplier and place of supply in the same state) you split the tax into CGST and SGST. For an inter-state supply (different states, or exports) you charge a single IGST at the combined rate instead.
Can I bill an unregistered client with a GST invoice? +
Yes. A registered supplier still issues a tax invoice and charges GST when supplying an unregistered customer. You record your own GSTIN; the recipient simply has no GSTIN to show. The place-of-supply rules still decide whether you apply CGST + SGST or IGST.
Does this template calculate the tax for me? +
The generator adds up taxable values and applies the CGST/SGST or IGST rates you choose, then produces a clean PDF. It formats the invoice - it is not tax advice, so confirm rates and codes with your accountant.
