Hub · Singapore

Singapore e-invoicing with IRAS InvoiceNow. Peppol mandate, GST 9%, UEN.

IMDA has been Singapore's Peppol Authority since 2018, and IRAS is now staging the InvoiceNow mandate for GST-registered businesses from 1 May 2025, with broader rollout from 1 April 2026 onwards. This hub covers four guides on the system, the 9% GST rate, ACRA's UEN and Bizfile, and the 5-corner model that adds IRAS as a fifth participant.
