Frequently asked questions
Can I show prices including GST?
Yes. Switch to tax-inclusive mode. If GST is exactly one-eleventh of the total, the ATO accepts a statement that the total price includes GST. [1]
I'm not registered for GST. What should I use?
Issue an ordinary invoice without GST: choose the generic preset and set tax to 0%. Only GST-registered businesses issue tax invoices.
