E-filing Your Company’s Estimated Chargeable Income (ECI) to IRAS

From YA 2020 onwards, e-Filing of the ECI is compulsory for all companies, unless exempted.

When it comes to the process of paying your company’s taxes, Estimated Chargeable Income (ECI) is the first and foremost matter to take note of. 

Estimated Chargeable Income, or ECI in short abbreviation, is an estimated calculation of your company’s taxable income, and essentially equivalent to paying your corporate tax in advance.

The deadline for ECI e-filing is within 3 month from your company’s Financial Year End (FYE). For example, if your company’s FYE is on 31st December 2020, the ECI for YA 2021 must be submitted by 30th March 2021.

If you file your ECI early, you may be eligible to pay your taxes in GIRO instalments. Singapore companies can enjoy up to 10 interest-free monthly instalments when they e-file their ECI on time.

To file your ECI, you may either log in to my Tax Portal with your company’s authorisation and UEN, or you may assign a Tax Agent like Leftright Corporate to file on your behalf.

Getting Your Tax Notice

After IRAS has processed your company’s ECI, you will receive a Notice of Assessment (NOA) that states the amount of tax to be paid. The full amount of tax stated must be paid within one month from the date of the NOA, unless you are paying via GIRO instalment.

Paying Your Company’s Tax (After receiving NOA)

Generally, there are two main methods to pay your taxes, Payment via GIRO or Payment via other Electronic Modes.

1. Payment via GIRO [Most popular]

Unlike the other payment methods, companies who opt to pay for their taxes by GIRO will be offered payment schedules through instalments. To be eligible for instalment plan, your company must be Singapore-registered and have an existing GIRO arrangement for Corporate Tax. If you do not have an existing GIRO arrangement, we recommend setting up your GIRO arrangements at least 3 weeks before e-filing of ECI. You may sign up for GIRO by completing an application form here.

1.1 GIRO Instalment Plan

Up to 10 instalments are available for all Singapore-registered Companies, and the number of instalments granted depend on the promptness of your ECI submission. The cut off date for allowable instalments will be by 26th of each qualifying month.

Filing Your Corporate Income Tax (Form C/C-S)

Last but not least, Corporate Income Tax (Form C/C-S) is a report of your company’s actual taxable income, and differs from ECI, which is an estimate of your company’s taxable income.

From YA 2020 onwards, e-filing of Corporate Income Tax is mandatory for all companies and must be submitted to IRAS through myTax Portal by 30th November annually.

If there are any discrepancies between your ECI calculation and Form C/C-S tax payable amount, IRAS will either refund you (in case of overpayment) or send you a notice of payment (In case of underpayment).
