Singapore E-Invoicing FAQ

Is e-invoicing mandatory in Singapore?

Yes, in phases. IRAS's GST InvoiceNow Requirement has applied since 1 November 2025 to companies that register for GST voluntarily within six months of incorporation, and since 1 April 2026 to every new voluntary GST registrant. Existing GST-registered businesses follow by total annual supplies in their 2025 GST returns: up to S$200,000 from 1 April 2028, together with new compulsory registrants; up to S$1 million from 1 April 2029; up to S$4 million from 1 April 2030; and above S$4 million from 1 April 2031. IRAS has notified businesses registered before 2026 of their implementation date. Confirm your own start date against IRAS's guidance.

What is UEN and how is it used?

UEN (Unique Entity Number) is Singapore's standard business identifier. It serves as your Peppol participant ID on InvoiceNow, making it easy for trading partners to find and send you invoices.

Are there grants for InvoiceNow adoption?

Yes, SMEs can apply for the Productivity Solutions Grant (PSG) to offset the cost of adopting InvoiceNow-ready solutions. Check IMDA's website for current grant availability. Also see our e-invoicing whitepapers and API documentation.
