Singapore's zero-rating regime for exports is one of its most important trade incentives: no output GST is charged on exported goods or qualifying international services, yet the exporter retains the right to claim input GST on purchases used to make those supplies. Correct TradeNet customs documentation, proof of export and accurate InvoiceNow records are all essential for IRAS to accept the zero-rating claim on audit.
Export invoices are accidentally issued with 9 % GST — overstating the price for the overseas customer and creating an IRAS correction backlog when the error is discovered at the F5 filing.
Automatic zero-rating applied to export transactions based on customer country and supply type, with a clean InvoiceNow-compatible Peppol record and a digital flag linking the invoice to the TradeNet export permit.
Export evidence — shipping documents, customs export permit, proof of payment — is held across different folders and is unavailable when IRAS requests supporting documentation during a compliance review.
Structured document archive linking each export invoice to its TradeNet customs permit, shipping evidence and payment record — retrievable as a single package at audit.
Correct GST treatment applied automatically, audit-ready evidence archive maintained continuously.
