What is GST?

Learn what GST is and when it may matter for Australian small businesses.

Summary

GST is a goods and services tax that can apply to many goods, services and other things sold or consumed in Australia. Businesses may need to register for GST when they meet ATO requirements.

What this means

GST affects pricing, invoices, business activity statements, and GST credits. Not every business is registered for GST, and registration depends on the rules and thresholds set out by the ATO.

Once registered, a business generally has ongoing GST reporting and record-keeping obligations.

Typical actions

  • Check whether GST registration applies.
  • Review whether sales are taxable, GST-free, or input taxed.
  • Issue tax invoices where required.
  • Keep records for GST reporting.
  • Lodge BAS if required.
