Australia’s GST in brief

Australia applies a single 10% GST — there is no reduced-rate ladder. Instead, specific categories are GST-free (0%: most fresh food, health and medical items, education, childcare, exports) or input-taxed (such as residential rent and many financial services, where input GST cannot be reclaimed). Prices in shops are shown GST-inclusive; business quotes are often excluding.

Adding and removing 10% GST

Ten percent is comfortably the easiest rate to do mentally: divide the net by 10 and add it on.

  • $100 net → $110 GST-inclusive (GST $10).
  • $110 ÷ 1.1 = $100 net (GST $10).
  • $250 net → $275; $880 gross → $800 net (GST $80).

Registration and BAS basics

  • Registration threshold: $75,000 annual turnover ($150,000 for non-profits) — or immediately for taxi and ride-share drivers, who register regardless of turnover.
  • Reporting: GST is reported through the Business Activity Statement (BAS), usually quarterly for smaller businesses, monthly for larger ones.
  • Tax invoices: sales over $82.50 including GST normally require a tax invoice showing the GST amount separately.
  • ABN: your Australian Business Number goes on invoices; without it, customers may withhold tax from payments to you.
