What this template is
A ready-to-use tax invoice in Excel, laid out the way IRAS expects a Singapore tax invoice to look: your company name, UEN and GST registration number, the words "Tax Invoice", an itemised table, and GST shown as a separate line at 9% (the prevailing rate since 1 January 2024).
Type your details once, fill in the line items, and the subtotal, GST and total calculate themselves. A payment block at the bottom tells your customer exactly how to pay you by PayNow or bank transfer, with the invoice number as reference — the single biggest fix for unmatched payments.
How to use it
- Download the file and replace the [bracketed placeholders] with your company name, UEN, address and GST registration number.
- Set the invoice number, invoice date and due date. Keep a running sequence (INV-0001, INV-0002 …) — IRAS expects serially numbered invoices.
- Fill in the Bill To block with your customer’s registered name and address.
- Enter each line item with quantity and unit price — the amount, subtotal, 9% GST and total compute automatically.
- Update the PayNow UEN and bank details in the payment block, then save as PDF (File → Save As → PDF) before emailing it.
Made for Singapore
- GST is calculated at 9%, the prevailing rate since 1 January 2024. If you are not GST-registered, delete the GST row and the GST registration number line — non-registered businesses must not charge GST.
- A tax invoice must show your GST registration number, the invoice date, an identifying number, and the GST amount separately — this layout covers all IRAS format requirements.
- The payment block uses PayNow Corporate (UEN) so customers can pay without asking for your bank account number.
- Keep issued invoices for at least 5 years — IRAS record-keeping requirement.
Frequently asked questions
Do I need to charge GST on my invoices?
Only if you are GST-registered. Registration is compulsory once taxable turnover exceeds S$1 million (retrospective or forecast basis). If you are not registered, you must not charge GST — remove the GST line from the template.
What must a Singapore tax invoice include?
The words "Tax Invoice", your business name, address and GST registration number, an invoice number and date, the customer’s name and address, a description of the goods or services, and the GST amount shown separately. This template includes all of these fields.
Can I use this template if I invoice in a foreign currency?
Yes, but for GST purposes IRAS requires the GST amount to also be shown in Singapore dollars, converted at an approved exchange rate. The template is set up for SGD; add an SGD conversion line if you bill in other currencies.
How is this different from a receipt?
An invoice requests payment; a receipt acknowledges payment received. If a customer pays on the spot, issue a receipt — we have a free Singapore receipt template too.
