Corporate Tax Filing Services
Supporting businesses in Singapore with tax compliance, filing, and reporting requirements.
All Singapore companies must e-file their Corporate Income Tax Returns with IRAS by 30 Nov annually.
In Singapore, taxes are based on the preceding year’s profits. For example, if your financial year ends on 31 Dec 2023, the profits earned in 2023 will determine the tax returns you file in 2024.
Stay on top of tax obligations well before deadlines.
Your company must file two Corporate Income Tax Returns with IRAS every year:
Estimated Chargeable Income (ECI) and Form C-S/ Form C-S (Lite)/ Form C.
Estimated Chargeable Income (ECI)
- Submit an estimate of your company’s taxable income for a Year of Assessment (YA).
- All companies, including new ones, must file their ECI within three months from the end of their financial year unless they qualify for an ECI filing waiver or are exempted from filing.
Details from IRAS to confirm if your company is required to file an ECI.
Form C-S/ Form C-S (Lite)/ Form C
- Report your company’s actual taxable income for a Year of Assessment (YA).
- Filing notifications are issued by IRAS by May each year.
- The filing deadline is 30 Nov annually.
Details from IRAS to determine whether your company should file Form C-S, Form C-S (Lite), or Form C.
