If a taxpayer’s business has a GST turnover of $10 million or more, they need to use full BAS reporting instead of ‘simpler BAS’, and account for GST on a non-cash (accruals) basis.
If their business has a GST turnover of $20 million or more, they need to report GST monthly on their BAS instead of quarterly.
The ATO is moving some businesses to the correct GST reporting and accounting methods from 1 July 2026, although taxpayers can voluntarily make the switch now in ‘Online services for business’ on the ATO’s website (Editor: Or contact us for assistance).
