How does the GST Invoice Generator work?

The KaroTools GST Invoice Generator helps you create professional tax invoices instantly. It automatically calculates CGST and SGST for local sales, or IGST for inter-state sales based on the GST rate you select. Once your details are filled, you can download a professionally formatted PDF. Learn more in our GST Invoice Format Guide.

Intra-state Tax = CGST (Rate/2) + SGST (Rate/2)

Inter-state Tax = IGST (Full Rate)

What Details Are Required in a GST Invoice?

If you have recently completed your GST registration, it's critical to format your bills correctly. Rule 46 of the CGST Rules prescribes invoice particulars applicable to the transaction, including:

  • Your Business Name, Address, and GSTIN
  • Buyer's Name, Address, and GSTIN (if they are a registered business)
  • Unique, consecutive Invoice Number and Date of Issue
  • HSN/SAC Code for each item or service
  • Taxable value of supply
  • Rate and exact amount of taxes (CGST, SGST, IGST)

CGST, SGST and IGST in GST Invoice

Our generator automatically handles the tax math. However, understanding the difference is key to compliance. Read our complete guide on IGST vs CGST vs SGST to learn exactly when to apply each tax type. In short: charge IGST if your client is in a different state, and CGST + SGST if they are in the same state. Note that if you are opted into the GST Composition Scheme, you issue a "Bill of Supply" instead of a tax invoice and cannot collect GST.
