What it does

Estimate the GST labels on a business activity statement from your period totals, on a cash or accrual basis, for the simpler or full reporting method.

Ask your AI

Estimate a period's BAS GST return in Australia. Ask me for any detail you need first, then show the result with its source and date, and list anything a person should check.

What comes back

Simpler BAS returns G1, 1A and 1B; full reporting adds G2, G3, G10 and G11.

Good to know

  • Simpler BAS returns G1, 1A and 1B; full reporting adds G2, G3, G10 and G11.
  • Omitted GST-free or input-taxed sales are assumed nil and mark the estimate incomplete.
  • Labels omit cents, as the statement does.
