How GST Works in Singapore

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 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 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.

Charging and Collecting GST

Once you have registered for GST, you must charge GST on your supplies at the prevailing rate. 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 asinput 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.

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.
