Corporate Tax Filing Singapore — ECI, Tax Computation & Form C-S / Form C
SBS supports Singapore companies with corporate income tax compliance, from Estimated Chargeable Income (ECI) and tax computation through to the applicable annual corporate tax return, including Form C-S, Form C-S (Lite) or Form C where relevant.
Fee depends on filing type, transaction volume and tax complexity. ECI, tax computation and annual return work may be quoted separately or together.

Common Questions
What is ECI?+
Estimated Chargeable Income is an estimate of a company’s taxable profits for the relevant Year of Assessment. Companies generally file ECI within 3 months after financial year-end unless they qualify for an administrative concession or specific exemption.
What is the difference between Form C-S and Form C?+
Form C-S is a simplified corporate income tax return for qualifying Singapore companies. Form C applies where the company does not meet the Form C-S eligibility conditions or otherwise needs to file Form C. Form C-S (Lite) is available to qualifying companies with lower annual revenue.
Do I need financial statements before filing corporate tax?+
You should have reliable financial statements and a tax computation before the annual corporate tax return is completed. If the accounts are not ready, SBS can assess the required accounting or financial-statement work separately.
Can SBS file only ECI?+
Yes. ECI can be separately scoped where only that filing is required. SBS can also quote the full tax cycle including tax computation and the annual corporate tax return.
Can SBS prepare the unaudited financial statements too?+
Yes. Unaudited financial statements can be quoted separately or together with corporate tax work. Combining both can simplify year-end coordination where the accounts are ready.
How much does corporate tax filing cost?+
SBS’s published fee guidance starts from S$200 for lower-volume corporate tax work, excluding GST. The actual fee depends on whether the engagement covers ECI, tax computation, Form C-S/Form C and any additional tax complexity.
