What is a GST invoice?

A GST invoice is a tax invoice issued by a business registered for Goods and Services Tax. It has to identify both parties by their registration number and show the GST charged separately, so the recipient can claim an input tax credit.

GST exists under that name in India, Australia, Canada, New Zealand and Singapore, and the details differ in each. What follows is common to all of them; check your local rules for thresholds and wording.

What a GST invoice should include

Use the Tax ID field for your GSTIN or equivalent registration number, and set the GST rate on each line.

• Recipient name, address and registration number where they are registered
• A sequential invoice number and the date of issue
• Description, quantity and taxable value of each supply
• The GST rate and GST amount per line
• The total GST and the total amount payable

GST in India: CGST, SGST and IGST

Indian GST splits into central and state components for supplies within a state, and a single integrated tax for supplies across state lines. The generator prints a combined GST figure per line; where you need the split shown explicitly, add the breakdown to the notes field, which prints in full on the PDF.
