About Us

The Inland Revenue Authority of Singapore (IRAS) is the main tax administrator to the Government. We collect taxes that account for about 70% of the Government's Operating Revenue, supporting Singapore's economic and social programmes to achieve quality growth and an inclusive society. We represent the Government in tax treaty negotiations, draft tax legislations and provide advice on property valuation to the Government. Beyond tax collection, IRAS supports the Government in disbursing various support grants to enterprises.
