Four BAS deadlines a year
Short answer
Quarterly BAS is due on 28 October, 28 February, 28 April and 28 July, and your BAS shows your own due date. Late payments can attract interest (GIC), so pay in full and on time. Tax7 lodges BAS for you from $149 per quarter ex GST, and BAS is free with a bookkeeping plan (plans from $190 a month ex GST).
