Invoice Generator for Singapore Businesses
Singapore GST-registered businesses must issue tax invoices showing their GST registration number and the GST amount separately. From 2024 the rate is 9%, and e-invoicing via InvoiceNow is being phased in.
What a Singapore invoice must show
- The words "Tax Invoice"
- Your GST registration number
- Invoice number and date
- Customer name and address
- Description, quantity and price of goods or services
- GST rate and GST amount shown separately
- Total including GST
Singapore invoicing notes
- GST registration threshold is SGD 1 million turnover.
- Zero-rated supplies include exports and international services.
- GST on imported services (reverse charge) applies to many B2B purchases.
Requirements change. This page reflects common practice for Singapore; confirm with your accountant or the tax authority before relying on it.
Frequently asked questions
Do I need to show GST separately on a Singapore invoice?
Yes. The GST amount must be shown separately from the net amount, along with the rate applied and your registration number if you are registered.
What currency should a Singapore invoice use?
Invoices are normally issued in SGD (S$). Cross-border invoices may use another currency, but state it explicitly and show the exchange basis if tax is involved.
Is this Singapore invoice format legally compliant?
The generator includes the fields most tax authorities require — sequential numbering, registration numbers, rate and amount shown separately. It is a template, not tax advice; confirm specifics with your accountant.
