What is GST in Singapore?
GST (Goods and Services Tax) in Singapore is a broad-based consumption tax levied on the import of goods as well as nearly all supplies of goods and services in Singapore. The current GST rate is 9%, effective from 1 January 2024. Businesses with an annual taxable turnover exceeding S$1 million are required to register for GST with IRAS. GST-registered businesses must charge and account for GST on their taxable supplies, file quarterly GST returns, and may claim input tax credits on business purchases.
Examples:
- Standard-rated supply (9%): most goods and services sold in Singapore
- Zero-rated supply (0%): export of goods, international services under Section 21(3)
- Exempt supply: sale and rental of residential properties, financial services
- Out-of-scope supply: private transactions, transfer of business as a going concern

Singapore Invoicing Tips
Consider voluntary GST registration even if your turnover is below S$1 million. It enhances business credibility and allows you to claim input tax on business purchases, which can be beneficial if your clients are primarily GST-registered businesses.
Use the Peppol e-invoicing network through Singapore's InvoiceNow initiative. IMDA actively promotes e-invoicing adoption, and many government agencies and large corporations prefer receiving invoices through Peppol for faster processing and payment.
Include clear payment terms on every invoice. Common terms in Singapore are 30 days from invoice date. Specify accepted payment methods such as PayNow (linked to your UEN or mobile number), GIRO, bank transfer, or cheque.
Keep all business and tax records for at least 5 years from the relevant Year of Assessment. IRAS can request records for verification at any time, and inadequate record-keeping can lead to estimated assessments and penalties.
For cross-border services, determine whether your supply is zero-rated under Section 21(3) of the GST Act. International services provided to overseas persons may qualify for zero-rating, meaning you charge 0% GST but can still claim input tax on related expenses.
File your GST returns quarterly via the IRAS myTax Portal by the due date (one month after the end of each accounting period). Late filing attracts a penalty of S$200 immediately, with an additional S$200 per month the return remains outstanding, up to S$10,000.

Frequently Asked Questions
What information is required on a Singapore invoice?
A Singapore tax invoice must include your business name and address, GST registration number, customer name and address, a unique sequential invoice number, invoice date, description of goods or services, quantity and unit price, total amount excluding GST, GST rate (9%), GST amount, and total amount including GST. IRAS prescribes at least 12 fields for a valid tax invoice.
What is the current GST rate in Singapore?
The GST rate in Singapore is 9%, effective from 1 January 2024. This was increased from 8% (which applied from 1 January 2023 to 31 December 2023). The previous rate was 7%. Some supplies are zero-rated (0%) such as exports and international services, while others are exempt from GST entirely, such as the sale of residential properties and certain financial services.
Do I need to register for GST in Singapore?
You must register for GST if your taxable turnover exceeded S$1 million in the past 12 months (retrospective basis) or is expected to exceed S$1 million in the next 12 months (prospective basis). Registration must be made within 30 days of becoming liable. Voluntary registration is possible below this threshold but commits you to remaining registered for at least two years and complying with all GST obligations.
What is a simplified tax invoice in Singapore and when can I use it?
A simplified tax invoice can be issued for supplies totalling S$1,000 or less (GST-inclusive). It requires fewer details than a full tax invoice: your business name, GST registration number, invoice date, description of goods or services, and the GST-inclusive total with a statement that the price includes GST. Your customer can use a simplified tax invoice to claim input tax if the amount does not exceed S$1,000.
Can I use this Singapore invoice template for international clients?
Yes. When invoicing international clients from Singapore, your services may qualify for zero-rating under Section 21(3) of the GST Act if they are considered international services. This means you charge 0% GST instead of 9%, but you can still claim input tax on related business expenses. You should determine whether the place of supply rules and specific conditions for zero-rating are met. Consult IRAS guidelines or a tax professional for complex cross-border arrangements.
What are the penalties for late GST filing in Singapore?
IRAS imposes a penalty of S$200 immediately when a GST return is not filed by the due date (one month after the end of each prescribed accounting period). An additional S$200 is charged for every complete month the return remains outstanding, up to a maximum penalty of S$10,000. IRAS may also issue an estimated assessment of the GST payable and charge a 5% late payment penalty on the estimated tax.
What is InvoiceNow and should I use it for Singapore invoicing?
InvoiceNow is Singapore's national e-invoicing initiative, built on the international Peppol network and promoted by IMDA (Infocomm Media Development Authority). It allows businesses to send and receive e-invoices in a standardized digital format directly between accounting systems. While not yet mandatory for all businesses, adoption is growing and InvoiceNow is increasingly expected by government agencies and larger enterprises. Using it can reduce processing time, lower costs, and improve accuracy.
How long must I keep invoice records in Singapore?
You must keep all business and accounting records, including invoices, for at least 5 years from the relevant Year of Assessment. IRAS can request records for verification at any time within this period. Records can be kept electronically provided they are in a readable format and can be produced for inspection when required.
