GST Output Tax: Customer Accounting for Prescribed Goods

Key requirements

Customer accounting has applied since 1 January 2019 to a local business sale of prescribed goods exceeding S$10,000 before GST to a GST-registered customer, unless an exception applies. Prescribed goods comprise qualifying mobile phones, memory cards and physically packaged off-the-shelf software; USB flash drives and equipment with pre-loaded software are excluded. Count only prescribed goods when a sale includes other items. The supplier issues a customer-accounting invoice with the customer’s GST number and the required statement, reports the sale in Box 1, and does not collect or report its GST in Box 6. The customer reports the purchase as output in Boxes 1 and 6 and, if eligible with valid evidence, claims input in Boxes 5 and 7. Occasional purchases can also be covered. The S$10,000 threshold is not permission to split transactions artificially.
