How GST is calculated in Australia

In Australia, the statutory goods and services tax rate of 10% is applied to taxable products and services.

Add Tax (Exclusive): Gross = Net × (1 + 0.1)

Reverse Tax (Inclusive): Net = Gross ÷ (1 + 0.1)

Extracted Tax: Tax Amount = Gross - Net

Invoicing & Compliance Best Practices

  • Tax Invoices: Clearly separate the pre-tax net sum from the statutory 10% GST line item.
  • Reverse Charge: For cross-border B2B purchases, verify whether reverse-charge accounting mechanisms apply under local regulations.
  • Exemptions: Certain essential items (such as healthcare, education, or staple foods) may qualify for zero-rating or reduced rates.
