Cómo funciona
Australia charges a flat 10% GST on taxable supplies. For a net price of $200.00 AUD, 10% tax is $20.00 AUD, making the gross total $220.00 AUD. Removing GST from $220.00 AUD (dividing by 1.10) recovers the $200.00 AUD base.
Preguntas frecuentes
Why is Australian GST described as one-eleventh of the price?
Because gross prices include 10% tax on the base price (110%), the tax portion inside the total is exactly 10 ÷ 110, or 1/11th of the inclusive price.
Which items are GST-free in Australia?
Under ATO guidelines, basic groceries, medical treatments, eligible health devices, and certain education courses are GST-free (0%).
Can I calculate GST on second-hand goods?
Yes. Input the purchase or selling price and the 10% rate to determine the standard tax component for your transaction records.
