  • GST is 10% of the value of a taxable supply, and the value is the GST-inclusive price × 10/11 (GST Act ss 9-70, 9-75). So GST is one-eleventh of a GST-inclusive price.
  • GST-free supplies (Division 38: certain food, health and education) and input-taxed supplies (Division 40: such as residential rent) carry no GST. Amounts here are rounded to the cent.

GST: $100.00 included in the price (1/11)
