IRAS asks a tax invoice to show your address, your GST registration number, the customer's name, the customer's address. A simplified tax invoice (total $1,000 or less including GST) can leave out the customer's name and address.

Invoice questions

What must a tax invoice show in Singapore?

IRAS lists: the words "Tax Invoice", your name and address, your GST registration number, the invoice date, an invoice number, the customer's name and address, a description of the goods or services, the GST rate, the total excluding GST, the total GST, and the total including GST. This template prints all of them and lists any you have left blank.

IRAS: Invoicing customers

Tax invoice or plain invoice: which one do I need?

Only a GST-registered business charges GST and issues tax invoices. IRAS says you must issue a tax invoice when your customer is GST-registered, generally within 30 days from the time of supply; for customers who are not GST-registered you may issue a receipt instead. If you are not GST-registered, switch GST off and the template prints a plain invoice with no GST.

IRAS: When to issue a tax invoice

What is a simplified tax invoice?

When the total including GST is $1,000 or less, IRAS lets you issue a simplified tax invoice with fewer details: your name, address and GST registration number, the date, an invoice number, a description, the total including GST, and a statement such as "price payable includes GST". The full tax invoice this template prints is accepted at any amount.

How does the template work out the GST?

It applies 9% to the total of the items and rounds the GST to the cent, one of the two methods IRAS accepts (the other is 9% on each item, then added up); whichever you use, use it consistently. If your prices already include GST, tick that option: the GST is then 9/109 of the total, and the invoice shows the amount excluding GST, the GST and the total separately, as IRAS requires.

IRAS: Calculate GST on tax invoices

Is my GST registration number the same as my UEN?

For some businesses it is; others have a separate GST registration number, such as M2-1234567-K. Print the number IRAS registered you under. If the two are the same, you can enter it in both fields.

IRAS: GST registration number formats

How long must I keep my tax invoices?

IRAS asks you to keep the tax invoices you issue, and those your suppliers give you, for at least 5 years. You do not submit them with your GST returns.

IRAS: Tax invoice

Does a PDF invoice meet the InvoiceNow requirement?

No. IRAS is requiring every GST-registered business to send invoice data to IRAS through InvoiceNow, Singapore's Peppol e-invoicing network, in phases from 2025 to 2031. A PDF is still a valid tax invoice to give your customer, but it does not send anything to IRAS. Onehub's InvoiceNow sending is on our roadmap and is not live yet.
