Estimated Chargeable Income (ECI) — the income of a company after deducting tax-allowable expenses. ECI is a necessary piece of data a company submits to IRAS within 3 months from the end of their financial year. It is then compared to the chargeable income stated in Form C-S/ C and either the excess tax is refunded, or you must pay the remaining tax within 1 month.
