Singapore invoice answer

Use one Singapore business invoice format for GST, SGD totals, and payment records

A Singapore invoice should make the supplier, customer, invoice number, currency, tax treatment, GST amount, and total payable easy to verify. GST-registered sellers can use the tax invoice fields, while non-GST sellers can keep GST out of the invoice.

Singapore market: the official IRAS rate and invoicing guidance were checked on 14 September 2026. IRAS listed GST at 9%. Recheck the current GST rate and tax invoice requirements before issuing a tax invoice and after any announced policy change. Do not apply US sales-tax or 1099 assumptions to this Singapore template.

Singapore invoice use cases

Separate tax invoice, standard invoice, and zero-rated scenarios

Singapore billing can look different depending on whether the seller is GST registered, whether the customer is GST registered, and whether the sale is local, zero-rated, or exempt.

GST-registered B2B sales

Issue a tax invoice with GST registration number, GST rate, GST amount, and total payable including GST.

Non-GST billing

Create a standard Singapore invoice that still shows UEN, SGD amount, due date, payment method, and business contact details.

Exports and zero-rated items

Separate standard-rated, zero-rated, exempt, or other supplies so the invoice is easier to reconcile later.

Service retainers

Use the format for monthly services, deposits, progress billing, or final invoices with clear balance due.

Singapore Invoice Template

Singapore's straightforward 9% GST system makes invoicing simpler than many other jurisdictions, but the city-state's business culture is precise about what must appear on every commercial document. Eonebill's Singapore Invoice Template is built for the Lion City's requirements: UEN numbers prominently displayed, IRAS-compliant GST calculations, SGD currency formatting, and all fields that Singapore businesses and their clients expect to see. Whether you run a fintech startup in the CBD, a logistics company in Jurong, or a freelance design practice in Tiong Bahru, this template produces clean, professional, IRAS-compliant invoices in seconds.

What Makes a Singapore Invoice Different

Singapore occupies a unique position in Southeast Asia's business landscape. It is one of the most trade-friendly jurisdictions in the world, with a GST system that is deliberately simple compared to India's multi-tier structure or France's e-invoicing mandates. The current 9% GST rate applies uniformly to most goods and services, with exemptions for financial services, residential property leases, and investment precious metals. This simplicity means Singapore invoices can focus more on clarity and professionalism than on navigating complex tax calculations.

The most distinctive identifier on a Singapore invoice is the UEN (Unique Entity Number). Issued by the Government of Singapore, the UEN replaced the old Company Registration Number (Co. Reg. No.) format for official business communications. Every invoice, receipt, and official document should carry the UEN. For foreign companies operating branches in Singapore, a separate Singapore branch UEN is issued, which is distinct from the overseas parent company's registration number.

Singapore also operates a strict invoice-based record-keeping system under IRAS (Inland Revenue Authority of Singapore) regulations. GST-registered businesses must retain all tax invoices and receipts for at least five years. A compliant invoice from a GST-registered supplier must clearly show the GST registration number exactly as shown in the supplier's IRAS registration record, the word "GST" or "Goods and Services Tax," the GST amount charged, and the rate applied. Customers who are also GST-registered can use this information to claim input tax credits.

Key Requirements for Singapore Invoices

Legal Mandatory Fields

A GST-compliant Singapore invoice must include: the words "Tax Invoice" or "Invoice" prominently; supplier's business name and UEN; supplier's GST registration number; supplier's registered address; date of issue (invoice date); a unique invoice number; customer's business name and address; description of goods or services supplied; quantity and unit price; total amount excluding GST; GST rate applied (currently 9%); GST amount; total amount payable including GST; and payment terms. For GST-exempt supplies, the invoice must clearly state "Exempt Supply" or "Zero-rated Supply" as applicable.

Tax Identification Numbers

Singapore uses two primary identifiers. The UEN (Unique Entity Number) is the mandatory business identifier for all entities registered in Singapore: local companies show as 10 characters (e.g., 202012345A), and foreign companies show with an S or T prefix. A GST registration number should be copied exactly from the IRAS registration record. It may match the UEN or use a separate IRAS-issued format; businesses should not infer it from a generic M2 pattern. Sole proprietors and partnerships use their UEN from ACRA registration.

Currency and Number Formatting

Singapore invoices use Singapore Dollars (SGD, S$). The S$ symbol or the written form "SGD" appears before the amount without a space: S$1,250.00 or SGD 1,250.00. The standard international format with commas for thousands and a decimal point applies (e.g., S$125,000.00). Eonebill's Singapore template automatically formats all amounts correctly, and for international clients, supports dual-currency display showing USD equivalents alongside SGD.

Frequently Asked Questions

Everything you need to know about professional-services invoices

How do I know if I need to charge GST on my Singapore invoice?
If your annual taxable turnover exceeds SGD 1 million, you must register for GST and charge 9% GST on all taxable supplies. If you are voluntarily registered, you must also charge GST. If you are not registered, you must not charge GST on your invoices — doing so is an offence under the GST Act.
What is the difference between a tax invoice and a receipt in Singapore?
A tax invoice is issued when a sale occurs, showing the GST amount charged. A receipt is issued when payment is received, confirming the transaction. Both may be combined into a single document for simplicity. GST-registered businesses must issue a tax invoice within 30 days of supplying the goods or services.
Can Singapore businesses invoice in foreign currency?
Yes, but if the business is GST-registered, the GST must be calculated and shown in Singapore Dollars based on the exchange rate at the time of supply. Many Singapore businesses prefer to invoice in SGD for domestic transactions and specify the foreign currency equivalent in parentheses for international clients.
What are the penalties for not issuing proper GST invoices?
Under the GST Act, failing to issue a tax invoice when required, or issuing an incorrect invoice, can result in penalties of up to SGD 10,000 or twice the amount of tax involved, whichever is greater, for each offence. Repeated offences can result in higher penalties and potential prosecution.
Is there a minimum amount for GST invoicing in Singapore?
No minimum amount exists. GST at 9% applies to all taxable supplies regardless of the invoice value, even for amounts below S$1. However, for invoices under S$1,000, simplified tax invoices are permitted that do not need to show the customer's details. ---
