Estimated Chargeable Income (ECI) in Singapore: What Businesses Need to Know

What is Estimated Chargeable Income (ECI)?

ECI is an estimate of your company’s taxable income for a Year of Assessment (YA), before deducting tax exemptions.

In simple terms, it represents - Your company’s profit after tax adjustments, but before corporate tax exemptions.

When Must ECI Be Filed?

ECI must be filed within 3 months from the end of your company’s financial year.

For example:

• Financial year end: 31 December 2025

• ECI filing deadline: 31 March 2026

Can My Company Be Exempted from Filing ECI?

Yes. Your company does not need to file ECI if both conditions below are met:

1. Annual revenue not more than SGD 5 million, and

2. ECI is NIL for the relevant YA

However, if either condition is not met, ECI filing is mandatory.

Why Is ECI Important?

Filing ECI on time allows your company to:

• Enjoy instalment payment plans (GIRO) for corporate tax
