Inland Revenue Authority of Singapore (IRAS)

Overview

The Inland Revenue Authority of Singapore (IRAS) serves as Singapore's principal tax administration agency and was established on September 1, 1992. Operating under the Ministry of Finance and taking over from the former Inland Revenue Department, IRAS is charged with the collection of a broad spectrum of taxes that help fund essential government services and public programs.

The authority administers income tax, goods and services tax (GST), property tax, and stamp duties, among other tax types. In addition to its role in tax collection, IRAS offers policy advice to government bodies, supports the drafting of tax laws, and assists in the negotiation of international tax treaties. Initiatives such as the Auto-Inclusion Scheme for electronic submissions and simplified tax filing solutions promote compliance and public engagement, reinforcing Singapore's fair and efficient tax infrastructure.
