How this is calculated
The estimator mirrors the ATO quarterly BAS form. All sales and purchase figures should be entered GST-inclusive. GST is calculated as amount ÷ 11 (one-eleventh of the GST-inclusive total).
- G1 — total sales, GST-inclusive.
- G2 — export sales (GST-free).
- G3 — other GST-free sales.
- G9 — GST on sales = (G1 − G2 − G3) ÷ 11.
- G10 — capital purchases, GST-inclusive.
- G11 — non-capital purchases, GST-inclusive.
- G20 — GST on purchases = (G10 + G11) ÷ 11.
- W1 — total salaries and wages paid (excl. super).
- W2 — PAYG tax withheld from W1.
- T7 — PAYG instalment for the period.
Net amount payable = G9 − G20 + W2 + T7. A negative result means the ATO owes you a refund for the period.
