Small businesses that are on Simpler BAS will only need to report:
GST on sales (1A)
GST on purchases (1B)
total sales (G1).
They will no longer need to report:
export sales amount (G2)
other GST-free sales (G3)
capital purchases (G10)
non-capital purchases (G11).
The fields will only be editable if the prefill determines you can use full reporting.
