Goods and Services Tax (GST): What it is and how it works

Goods and Services Tax or GST is a broad-based consumption tax levied on the import of goods (collected by Singapore Customs), as well as nearly all supplies of goods and services in Singapore. In other countries, GST is known as the Value-Added Tax or VAT.

GST exemptions apply to the provision of most financial services, the supply of digital payment tokens, the sale and lease of residential properties, and the importation and local supply of investment precious metals. Goods that are exported and international services are zero-rated.

Taxable and non-taxable goods and services

Businesses required to register for GST

As a business, you must register for GST when your taxable turnover exceeds $1 million.

If your business taxable turnover does not exceed $1 million, you may still choose to voluntarily register for GST after careful consideration.

Please refer to our webpage for more information on whether you need to register for GST and the responsibilities of GST-registered businesses.

Charging and claiming GST

Only GST-registered businesses can charge and claim GST from their effective date of GST registration. Non-GST registered businesses are not allowed to charge or claim GST.

Charging GST 

If you are registered for GST, you must charge GST on all taxable supplies at the prevailing GST rate, except for supplies that are subject to customer accounting. The GST that you charge and collect is known as output tax. Output tax must be paid to IRAS within a month from the end of the accounting period. Refer to our page on filing and payment due dates for more information.

If you have wrongfully charged or collected GST, you must remit the GST wrongly collected to IRAS.


An exception where a non-GST registered person is required to charge and account for GST is when it sells or rents out a GST-registered business assets in satisfaction of a debt owed. This applies to non-GST registered third parties, such as mortgagees, financiers and auctioneers. For details on how to account for GST in such scenario, please refer to our page on selling/ renting out asset in satisfaction of debt .

Claiming GST

If you are registered for GST, you can claim the GST incurred on business purchases (including imports) and expenses, as input tax in your GST return. This is subject to you fulfilling the conditions for claiming input tax.

There are exceptions where non-GST registered businesses in specific industries are given concessions (subject to conditions) by the Minister to claim the GST incurred. These exceptions are:

  1. Qualifying funds that are managed by a prescribed fund manager in Singapore can claim GST incurred on prescribed expenses at an annual fixed recovery rate via remission.  

    Details of the GST remission (such as the types of qualifying funds, qualifying conditions, prescribed list of expenses and procedures to claim GST) are explained in the circular issued by the Monetary Authority of Singapore (MAS).
  2. Real Estate Investment Trusts and Qualifying Registered Business Trusts listed on the Singapore Exchange (i.e. S-REITs and qualifying S-RBTs) can claim GST on expenses incurred for their business and their Special Purpose Vehicles (SPVs).  
    This GST concession applies regardless whether the S-REIT or S-RBT is eligible for GST registration.

    For details, please refer to  GST: Concession for REITS and Qualifying Registered Business Trusts Listed in Singapore (PDF, 962KB)

To claim the GST incurred, qualifying funds, S-REITs and S-RBTs need to submit a quarterly Statement of Claims to IRAS within one month from the end of the respective quarters.

  As an administrative concession, funds and trusts may file their quarterly Statement of Claims after the due date, subject to the following conditions:

  1. The GST claims are made on tax invoices dated within the relevant quarter; and
  2. The quarterly Statements of Claims are filed within 5 years from the end of the relevant quarter.

For example: 

Period of claims: 1 Apr to 30 Jun

Qualifying funds, S-REITs and S-RBTs can submit the Statement of Claims latest by 30 Jun 2022.

Additionally, you may be able to claim GST incurred before GST registration or incorporation, provided that you fulfil certain conditions. For more information, please refer to our page on claiming GST incurred before GST registration/ incorporation. 

This input tax credit mechanism ensures the taxation of only the value-add at each stage of a supply chain.

Example 1: How a business charges output tax and claims input tax

A GST-registered manufacturer imports leather from overseas to manufacture a bag. The manufacturer sells the bag to a GST-registered retailer. Thereafter, the retailer sells the bag to a consumer.  
This is how GST works at each stage of the value chain:

1. ManufacturerPays GST to Singapore Customs for the import of leatherImport value = $100Import GST paid = 7% X $100 = $7 (input tax claimable from IRAS)
Charges and collects GST for sale of bags to retailerSelling price to retailer = $200GST charged to retailer = 7% X $200 = $14 (output tax payable to IRAS)
2. RetailerPays GST to ManufacturerPurchase value = $200GST paid = 7% X $200=$14 (input tax claimable from IRAS)
Charges and collects GST for sale of bags to end consumerSelling price to end consumer = $300GST charged to end consumer = 7% X $300 = $21 (output tax payable to IRAS)
3. End consumerPays GST to RetailerPurchase value = $300GST paid = 7% X $300 = $21End consumer is not GST-registered. Therefore, he cannot claim the GST paid on his purchase from IRAS.

Paying output tax and claiming input tax

If you are a GST-registered business:

  1. You must submit your GST return to IRAS within a month from the end of each prescribed accounting period. This is usually done on a quarterly basis.
  2. You should report both your output tax and input tax in your GST return.
  3. The difference between output tax and input tax is the net GST that is payable to IRAS or refundable by IRAS.
