Key Corporate Tax Deadlines in Singapore
Missing IRAS deadlines carries real consequences. Here's what every Singapore company needs to know:
- ECI Submission: Within 3 months from the end of your financial year.
- Form C-S / C Filing: 30 November of each year (e-filing via myTax Portal).
Late or non-filing is an offence under the Income Tax Act. IRAS may issue an estimated Notice of Assessment, impose penalties, and take further enforcement action. Companies with messy books or missed prior-year filings can come to us, we'll help you get back on track.

Frequently Asked Questions
A business tax accountant prepares and files your company's corporate income tax return with IRAS, ensures your financial records are tax-ready, computes your chargeable income, identifies eligible tax exemptions (such as the start-up tax exemption), and handles any IRAS queries on your behalf. At Margin Wheeler, your dedicated relationship manager coordinates the entire process so you don't have to chase anyone.
Margin Wheeler's corporate tax service starts from S$200 per year for straightforward cases. The final fee depends on the complexity of your accounts, number of transactions, and whether additional services like tax planning are required. Contact us for a transparent, no-obligation quote.

All Singapore-incorporated companies must e-file their Corporate Income Tax Return (Form C-S, Form C-S Lite, or Form C) by 30 November each year. Before that, your Estimated Chargeable Income (ECI) must be submitted within 3 months from the end of your financial year. Missing either deadline can result in IRAS penalties and estimated assessments. Margin Wheeler tracks these deadlines for you automatically.
Most newly incorporated Singapore companies qualify for the start-up tax exemption for their first 3 consecutive Years of Assessment, unless they are investment holding companies or involved in property development for sale. Qualifying companies enjoy a 75% exemption on the first S$100,000 of chargeable income and a further 50% on the next S$100,000 (YA 2022 onwards). Our team will confirm your eligibility and ensure the exemption is correctly applied when filing. If you want to know more, read our article on Startup Tax Exemption in Singapore!
