Our Revenue Collection

IRAS plays a key role in the collection of tax revenue, which is the main source of Singapore’s Government Operating Revenue (GOR). IRAS’ collection comprises a mix of direct and indirect taxes - taxes on income, Goods and Services Tax (GST), Property Tax, Stamp Duty and Betting Taxes.

Other sources of the GOR include Customs and Excise Duties, Taxes on Motor Vehicles, Vehicle Quota Premiums, other taxes, fees, charges and receipts.

Collectively, the revenue is used to fund government spending in support of social objectives, maintain strong security and external relations, and promote economic development.

In FY2016/17, a total of S$47.0 billion, or 68.2% of the GOR was collected by IRAS. This amount accounted for 11.3% of Singapore’s Gross Domestic Product.

IRAS' Tax Collection


The distribution of taxes collected by IRAS in FY2016/17 is shown in the chart. Income Tax (Corporate Income Tax, Individual Income Tax and Withholding Tax) made up 54% of IRAS’ collection. The amount collected was S$1.1 billion over the previous financial year due to higher collection from Individual Income Tax. Contributing to the increase were higher individual earnings and the cessation of oneoff personal tax rebates given in YA2015.

GST collection increased to S$11.1 billion in FY2016/17 from S$10.3 billion in FY2015/16.

Property Tax collection decreased marginally by 2.1% to S$4.4 billion in FY2016/17.

FY2016/17 Stamp Duty collection was S$3.3 billion, 18.4% more than the previous financial year due to a higher number of property transactions.

Betting Taxes comprising Betting Duty, Casino Tax and Private Lotteries Duty amounted to S$2.7 billion in FY2016/17, slightly lower than FY2015/16 by 1.4%.
