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.

Businesses Required to Register for GST

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

    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 webpage for more information on whether you need to register for GST.

    Charging and Collecting GST

    Once you have registered for GST, you must charge GST on your supplies at the prevailing rate with the exception of relevant supplies that are subject to customer accounting. This GST that is charged and collected is known as output tax. Output tax must be paid to IRAS.

    The GST that you incur on business purchases and expenses (including import of goods) is known as input tax. If your business satisfies the conditions for claiming input tax, you can claim the input tax on your business purchases and expenses.

    This input tax 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 for the manufacture of 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. Manufacturer

    Pays GST to Singapore Customs for the import of leather

    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 payable to 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 payable to 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 the GST paid on his purchase from IRAS.

    Paying Output Tax and Claiming Input Tax Credits

    As a GST-registered business:

    1. You must submit your GST return to IRAS one month after 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 payable to IRAS or refunded by IRAS.

    Output tax is the GST charged to your customers for goods and services you sell.
Input tax is the GST paid on your businesses purchases.
If Output tax > Input tax, the net GST is payable to IRAS.
If Output tax < Input tax, the net GST is refundable to you.

    • Why must Singapore implement GST?

      GST was introduced in 1 Apr 1994 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.
    • I am not GST-registered. Can I claim GST incurred on my business purchases?

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