For GST-registered businesses

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. The only exemptions are for the sale and lease of residential properties, the importation and local supply of investment precious metals and the provision of most financial services. Export of goods and international services are zero-rated. In some countries, GST is known as the Value Added Tax (VAT).

Export of goods

E.g. sale of laptop to overseas customer. The laptop is shipped to an overseas address by the supplier 

Sale and rental of unfurnished residential property 

Importation and local supply of investment precious metals
  • Sale where goods are delivered from overseas to another place overseas 
  • Private transactions 


Most local provision of services would fall under this category.

E.g. provision of spa services to customer in Singapore

Services that are classified as international services

E.g. air ticket from Singapore to Thailand (international transportation service) 

Financial services

E.g. issue of a debt security

As a business, you must register for GST when: 

  • Your taxable turnover for the past 12 months ending Mar, Jun, Sep or Dec (referred to as "quarter") is more than $1 million; or
  • You are making or intend to make taxable supplies and you can reasonably expect your taxable turnover in the next 12 months to be more than $1 million (e.g. signing of a sales contract or business agreement).

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

Please refer to our flowchart (compulsory or voluntary registration)  or e-Tax Guide Do I Need To Register? (194KB) for additional details. 

After registration, businesses must charge GST at the prevailing rate. This GST that they charge and collect is known as output tax, which has to be paid to IRAS. GST incurred on business purchases and expenses (including import of goods) are known as input tax. Businesses can claim input tax if conditions for claiming are satisfied. This credit mechanism ensures that only the value added is taxed at each stage of a supply chain. 


A GST-registered manufacturer imports leather from overseas and uses them to manufacture a bag. The manufacturer sells the bag to a GST-registered retailer. Thereafter, the retailer sells the bag to an end-consumer.

1. Manufacturer
  • Pays GST to Singapore Customs for imports

    Import value = $100
    Import GST paid = 7% X $100=$7 (input tax to claim from IRAS)
  • Charges and collects GST for sale of bags to retailer

    Selling price to retailer = $200
    GST charged to retailer = 7% X $200 = $14 (output tax to pay IRAS)
2. Retailer
  • Pays GST to Manufacturer

    Purchase value = $200
    GST paid = 7% X $200=$14 (input tax to claim from IRAS)
  • Charges and collects GST for sale of bags to end consumer

    Selling price to end consumer = $300
    GST charged to end consumer = 7% X $300 = $21 (output tax to pay IRAS)
3. End-consumer
  • Pays GST to Retailer

    Purchase value = $300
    GST paid = 7% X $300=$21

End consumer is not GST-registered. Therefore, he cannot claim GST paid on his purchase from IRAS.


How does a business pay output tax and receive input tax credits?

A GST-registered business is required to submit GST return to IRAS at the end of each prescribed accounting period (usually on a quarterly basis). The business will report its output tax and input tax for that prescribed accounting period in the GST return. The difference between output tax and input tax is the net GST payable to or refundable from IRAS.


Output tax to be paid = $30

Input tax to be claimed = $10 (i.e. input tax less than output tax)

Net GST payable to IRAS = $20


Output tax to be paid = $10

Input tax to be claimed = $30 (i.e. input tax more than output tax)

Net GST refundable from IRAS = $20


GST was introduced to enable Singapore to shift its reliance from direct taxes to indirect taxes. GST has also enabled Singapore to sustain a lower income tax rate. Being a tax on consumption, and not income, GST inherently encourages savings and investments.

No, if you are not a GST-registered business, you cannot claim the GST incurred on your purchases.
