What is ECI, and do you need to file it in Singapore?

ECI is your Estimated Chargeable Income, filed with IRAS within 3 months after your financial year-end. Here is when it is waived and when it is not.

ECI stands for Estimated Chargeable Income. It is an estimate of your company’s taxable profit for a financial year, and Singapore companies file it with IRAS within 3 months after the financial year-end.

You do not have to file ECI if both conditions are met: your company’s annual revenue is S$5 million or less, and your ECI is nil, meaning there are no taxable profits after deductions. If either condition is not met, ECI must be filed.

ECI is separate from the corporate income tax return. The return itself (Form C-S (Lite), Form C-S or Form C) is due by 30 November of the Year of Assessment. For a company with a 31 December year-end, for example, ECI is due by 31 March, while the return for that year is due the following 30 November.

The practical tip: keep your books current during the year. If your records are up to date, estimating chargeable income takes minutes. If they are not, ECI becomes a rushed guess that you may have to correct later.
