  • Country updates
Releases updated InvoiceNow FAQs Singapore currently does not require mandatory e-invoicing for B2B or B2G transactions, but taxpayers can issue them voluntarily via the InvoiceNow platform. The InvoiceNow network is based upon the Peppol network (Peppol BIS billing 3.0 standards), though VAT-related rules have been replaced by GST rules. The IMDA strongly recommends e-voicing although it is not mandated. The IMDA (Infocomm Media Development Authority) of Singapore has updated the FAQ related to InvoiceNow, which provides information on what InvoiceNow is, how it differs from PDF e-invoicing, and many other useful details. It is expected that Singapore will mandate the use of the InvoiceNow platform for B2G transactions in the near future , However no specific timeline has been revealed yet.

GST on imports of low valued goods  As of 1 Jan 2023, Singapore will implement GST on imports of low-value goods and non-digital services. The purpose of taxing low-value goods is to level the playing field between overseas and domestic vendors, also ensuring a fair and resilient GST system.  Overseas suppliers who sell low-value goods (S$400 or less) to customers in Singapore must register GST with Singapore's Overseas Vendor Registration (OVR) if the business:  
  • has an annual global turnover exceeding S$1 million; and 
  • makes B2C supplies of low-value goods to Singapore exceeding S$100,000.  
For more information, please refer to the e-Tax Guide.

  • if the customer of the service belongs in Singapore, the travel arranging service will be standard-rated; or
  • if the customer of the service belongs outside Singapore and the direct beneficiary either belongs outside Singapore or is GST-registered in Singapore, the travel arranging service will be zero-rated.
