How to Show GST on an Invoice

If you are GST registered, show GST clearly on tax invoices so clients can claim input tax credits and your records satisfy the ATO.

To show GST correctly:

Title the document "Tax Invoice"
Show each taxable line item amount (GST inclusive or exclusive — pick one and be consistent)
Display a subtotal of taxable sales
Show "GST" or "Total GST" as 10% of the taxable amount (if exclusive) or state "Total price includes GST"
Show the grand total payable

Example (GST exclusive): Subtotal $1,000 + GST $100 = Total $1,100. InvoiceSonic calculates and displays GST automatically based on your registration setting.
