The Singapore GST rate is 9%, in force since 1 January 2024. GST in Singapore applies to most goods, services and imports, and is administered by the Inland Revenue Authority of Singapore (IRAS). GST registration becomes compulsory once taxable turnover exceeds S$1 million.
This guide explains Singapore GST with the current rate, what is taxable, how GST registration works, and how to file returns on time.
What is GST in Singapore?
Goods and Services Tax (GST) is a broad-based consumption tax charged on most goods and services in Singapore, including imports.
In simple terms, GST is added to the price of a product or service. Businesses collect this tax from you and remit it to IRAS. This makes businesses tax collectors for the government.
Tax is applied at every stage of the supply chain, but only on the value added at each step. This ensures the final tax burden is ultimately borne by the end consumer, not the businesses themselves. GST is governed by the Goods and Services Tax Act 1993 and administered by IRAS.
GST Rate in Singapore 2026
The GST rate in Singapore is 9% in 2026. This is the standard rate applied to most goods and services supplied in the country, following the final step of a planned increase implemented by the government.
Quick overview:
-
Standard GST rate: 9%
- Effective since: 1 January 2024
- Applies to: Local goods, services, and imported goods
- Administered by: IRAS (Inland Revenue Authority of Singapore)
In general, most business transactions are subject to the 9% rate unless they are specifically classified as zero-rated or exempt.
How Does Singapore's GST Work?
Singapore’s GST works on a simple “collect and offset” system. When a business supplies goods or services, it charges GST to the customer. This is called output tax. At the same time, the business also pays GST on its own purchases, known as input tax.
At the end of each GST filing period, the business calculates the net position by calculating the difference: Output tax – Input tax = Amount payable or refundable.
This ensures tax is applied only on the value added by each business, not multiple times.
Which Goods and Services Are Subject to GST in Singapore?
GST in Singapore applies to most business transactions, but the treatment depends on the type of supply. Broadly, supplies are grouped into three categories.
1. Standard-Rated supplies (9%)
This is the most common category. GST at 9% applies to:
- Local sale of goods
- Business and professional services
- Retail transactions
- Digital services used in Singapore
- Imported goods
2. Zero-Rated Supplies
Some transactions are taxed at 0% GST, meaning no tax is charged, but businesses can still claim input tax. These include:
- Export of goods outside Singapore
- International services provided to overseas clients
3. Exempt Supplies
Certain supplies are completely exempt from GST, including:
- Sale and lease of residential properties
- Most financial services such as loans and insurance
- Selected investment precious metals
For these categories, GST is neither charged nor recoverable.
Under the Fourth Schedule of the GST Act, exempt financial services include:
- Bank account maintenance fees
- Currency exchange
- Issue or sale of shares and bonds
- Certain derivatives (no delivery of goods/services)
- Loans
- Life insurance policies
Who Needs to Register for GST in Singapore?
GST registration in Singapore is based mainly on your business turnover and expected sales. In simple terms, you must register if your business crosses a clear revenue threshold set by IRAS.
Mandatory GST Registration
GST registration in Singapore becomes compulsory when a business meets either of the following conditions:
- Your taxable turnover exceeds S$1 million at the end of a calendar year (retrospective test). Apply by 30 January of the following year; registration takes effect on 1 March.
- You reasonably expect taxable turnover to exceed S$1 million in the next 12 months (prospective test). Apply within 30 days of the forecast date. For liabilities arising on or after 1 July 2025, registration takes effect two months after the forecast date.
Once either condition applies, registration becomes compulsory, and you must start charging GST from your effective registration date.
Voluntary GST Registration
Even if your turnover is below S$1 million, you may choose to register voluntarily.
Businesses usually do this to:
- Claim GST on business expenses.
- Improve credibility with clients and suppliers.
- Prepare for future growth and compliance needs.
How to Register for GST in Singapore (Step-by-Step)
GST registration in Singapore is done online through the IRAS myTax Portal. The process is structured and requires businesses to provide key details about their operations, turnover, and supporting documents.
Step 1: Check if You Need a GST Registration
First, check if your turnover meets the threshold. GST registration becomes compulsory if your taxable turnover is more than S$1 million at the end of a calendar year or is expected to go above that amount in the next 12 months. If your turnover is below the threshold, you can still register voluntarily if it benefits your business.
Step 2: Prepare Your Business Information
Before applying, make sure your business details and documents are ready. This includes your company UEN, turnover figures, contact details, and basic financial records. Preparing everything early helps avoid delays later.
Step 3: Submit the Application Online
GST registration is done online through the IRAS myTax Portal. During the application, you’ll need to provide details about your business activities and estimated turnover. IRAS may also request supporting documents, depending on your business type.
Step 4: Wait for IRAS Approval
After submission, IRAS reviews the application. If more information is needed, they may contact you for clarification or additional documents. Approval time can vary depending on how complete the application is.
Step 5: GST Compliance After Approval
Once your registration is approved, IRAS will issue your GST registration number and confirm the effective date. From that date onwards, your business must start charging GST on taxable sales and follow GST filing requirements.
How Do You File GST Returns in Singapore?
GST-registered businesses file the GST F5 return online through the IRAS myTax Portal. Filing and payment are due 1 month after the end of each accounting period. For a quarter ending 30 September, the deadline is 31 October. A nil return is still required when there is no activity.
What happens if you are late?
-
Late filing: S$200 penalty, plus S$200 for each further completed month, capped at S$10,000 per return.
-
Late payment: 5% penalty on the unpaid GST. If still unpaid after 60 days, a further 2% per month may apply, up to 50%.
History of GST Rates in Singapore
Singapore introduced GST on 1 April 1994 at a rate of 3%. Since then, the rate has increased gradually.
|
Period |
GST Rate |
| 1994 – 2002 | 3% |
| 2003 | 4% |
| 2004 – 2007 | 5% |
| 2007 – 2022 | 7% |
| 2023 | 8% |
| 2024 onwards | 9% |
The increase from 7% to 9% was implemented in two stages:
- 8% from January 2023
- 9% from January 2024
The government stated that the increase was needed to support rising long-term spending, especially in healthcare and an ageing population.
Compared to many countries, Singapore has kept its GST system relatively simple, and the rate increases gradually, giving businesses time to adjust their pricing and operations.
Key Transitional Rules for GST Rate Changes
When GST rates change, businesses must apply the correct rate based on the transaction's timing. These are known as transitional rules.
Businesses must look at:
- Invoice date
- Payment date
- Delivery or service completion date
If a transaction happens across two GST periods, businesses may need to split the GST treatment between the old and new rates.
In general:
- Supplies completed before the rate change follow the earlier GST rate
- Supplies completed after the change follow the new GST rate
Businesses should also review contracts, invoices, accounting systems, and pricing to ensure the correct GST rate is applied during transition periods.
