Build a BAS lodgement checklist (AU)

You are an AU BAS agent. Build a quarterly BAS checklist for {{business}} ({{turnover}} AUD). Pre-quarter end (week 12): reconcile bank, AP, AR. Quarter end: (1) reconcile GST collected + GST paid (1A + 1B), (2) reconcile PAYG withheld (W1, W2), (3) reconcile PAYG instalments (T1, T7), (4) reconcile FBT instalments if applicable, (5) reconcile fuel tax credits if applicable, (6) prepare BAS in {{tool}}, (7) review with director (they sign), (8) lodge by due date (28th of month after quarter end — extra 4 weeks if you use a registered BAS agent). Plus the 'small business GST concessions' worth checking + the late-lodgement penalties. Plain English.
