Introduction

The invoice requirements for Singapore are laid out in the GST Act 1994.

General notes

When setting up your remit-to address, your Goods and Sales Tax ID (GST ID) must be in one of the following formats: 

  • X12345678X
  • 123456789X
  • X123456789
  • 9 characters, for example, 12345678X
  • XY12345678

All tax and total amounts must include the alternateAmount and alternateCurrency attributes. The alternate currency must be set to SGD. See Providing Amounts in Local Currency for more info.

When adding a tax exempt line or creating a reverse change invoice, add this element to your cXML:<Description xml:lang="en-US">Line level exemption reason</Description>

Include the <Description> element immediately after <tax-amount>. It's required when the TaxDetails category contains an exemption. See Add Tax Exemption Details to an Invoice fore more info.

As of January 1, 2019, Singapore introduced a new customer accounting scheme whereby the buyer rather than the seller will need to account for GST on purchases of mobile phones, smart cards and software exceeding SGP 10,000. This requirement only applies to GST registered taxpayers and domestic transactions. Where a sale falls within the scope of the customer accounting requirement, the invoice will need to clearly state the GST amount the customer needs to account via the following statement:

"Sale made under customer accounting. Customer to account for GST of $X."

Extrinsic fields

The following extrinsics are required to send a compliance-assured Singaporean invoice. You may require additional extrinsics specific to your industry or billing situation:
