    How this is calculated

    Australia and New Zealand charge a 10% Goods and Services Tax. This calculator adds GST to a net price or reverses it out of a GST-inclusive price for correct invoicing and repricing.

    1. GST = net x rate%
    2. Net from gross = gross / (1 + rate%)

    What to make of the number

    AU/NZ GST is a flat 10%. GST-registered sellers must show it separately on invoices.

    Frequently asked questions

    When is GST not charged?
    Exports out of AU/NZ are generally GST-free; some food and healthcare are exempt.
