What an invoice in Singapore must show

The Singapore preset carries a six-item checklist based on what a tax invoice usually needs, and each item maps to a field. Presets are starting points — confirm current rates and requirements with your tax authority.

The heading “Tax Invoice” when you are GST registered. The Document title changes to Tax Invoice automatically while the GST line has a rate. Remove the line and it reads Invoice again.

Your name, address and GST registration number. These go in From, where the ID label reads GST Reg. No.; the editor keeps them in your business profile so they are prefilled next time.

Invoice date and an identifying number. The Date prints as DD/MM/YYYY and the Invoice number counts up from the last one you issued, with a warning if you reuse a number.

The customer’s name and address. Bill to holds them, plus a UEN field. The UEN, or Unique Entity Number, is the identifier every business registered in Singapore has; printing it makes the invoice easy to match on the customer’s side. Individuals do not have one, so leave the field empty for private customers.

A description, quantity and amount for each item. One line per product, service or block of time, with Description, Qty, Unit and Rate. The Amount column is calculated.

The GST amount and the total including GST. The totals block shows the amount before GST, the GST line at 9% and the total. IRAS also allows a simplified tax invoice with fewer details for small amounts; fill in every field and you cover both forms.

The preset also selects SGD as the currency and A4 as the paper size, and adds a notes line, “Payment due within 30 days.” Payment details take your bank name and account number, or a Pay online link if you bill through a payment page.

GST at 9% in the invoice generator for Singapore

Singapore has a single GST rate, 9% since 1 January 2024, so the preset adds one GST line rather than a picker. Exports of goods and international services can be zero-rated: keep the line and set the rate to 0 so the invoice shows GST at 0% rather than no GST at all. Exempt supplies, such as most financial services and the sale or lease of residential property, carry no GST; remove the line for those. The 9% figure is a default as of the build date and is editable.

If you are not GST registered, remove the GST line, leave GST Reg. No. empty and the heading reads Invoice. Registration becomes compulsory when taxable turnover passes S$1 million, measured over a twelve-month period looking back or forward, and IRAS explains the two tests; voluntary registration is possible below that.

Prices quoted to consumers in Singapore are often GST-inclusive. Turn on tax-inclusive under Totals and the editor works backwards from the price you type, printing the amount before GST, the GST and the total. When you invoice in a foreign currency, IRAS expects the GST amount and total to be shown in Singapore dollars as well; the editor does not convert, so add the SGD figures in Notes.
