GST (Goods and Services Tax) is one of the most important indirect taxes that businesses in Singapore need to manage. It applies to most goods and services sold within the country and influences areas like pricing, invoicing, and tax reporting.
In 2026, the GST rate remains at 9%. Businesses must register for GST once their annual taxable turnover goes above S$1 million. After registration, they must add GST to their taxable sales and submit tax returns to the Inland Revenue Authority of Singapore (IRAS).
This guide explains everything businesses need to know about Singapore GST in 2026, including when to register, the current GST rate, what is taxable, and the main filing and compliance rules.
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 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 in the past 12 months, or
- You expect your taxable turnover to exceed S$1 million in the next 12 months.
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 in the past 12 months 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.
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.
- Export of goods outside Singapore
- International services provided to overseas clients

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.
