Singapore Mandates E-Invoicing for GST Registrants Starting November 2025: Key Dates and Compliance Steps

  • Singapore’s InvoiceNow e-invoicing system becomes mandatory for new voluntary GST registrants from 1 Nov 2025, all voluntary registrants from 1 Apr 2026, and will later expand to all GST-registered businesses.
  • Invoices must be submitted in PINT SG XML format via accredited Access Points; paper/PDF invoices require manual uploads.
  • The system automates tax compliance, reduces manual errors, speeds up payment cycles, and enables real-time reporting to IRAS.
  • Exemptions apply to overseas entities and businesses GST-registered only due to Reverse Charge rules.
  • Early adoption offers cost savings and automation benefits, while delays risk audits, penalties, and payment disruptions.
