Singapore’s corporate tax system is straightforward compared to many jurisdictions, but it still carries firm deadlines: every company must file its Estimated Chargeable Income (ECI) within three months of its financial year-end, and its full tax return (Form C-S or Form C) by 30 November each year. Singapore’s network of more than 70 Double Taxation Agreements and 20 Free Trade Agreements also means cross-border income doesn’t have to be taxed twice, if structured correctly. Pointer Services handles your corporate tax computation and filing with IRAS, and connects you to our specialist Withholding Tax and GST Registration services below.
