Australia’s Goods and Services Tax (GST) is a broad-based tax applied to most goods, services and other items sold or consumed in Australia. It is administered by the Australian Taxation Office (ATO). Businesses are identified by their Australian Business Number (ABN), an 11-digit identifier whose validity is confirmed with a weighted modulus-89 check.
