    Corporate Income Tax/ Employer-related Matters

    1. Budget 2020 Updates New!

    (i) Corporate Income Tax (CIT) Rebate for YA 2020
    Companies need not factor in the CIT rebate when filing their ECI for YA 2020 from 1 Mar 2020 as IRAS will compute and allow the rebate automatically.                                                                   

    Companies that have filed their YA 2020 ECIs and received the Notice of Assessment (NOA) that did not take into account the CIT rebate announced in the Budget 2020 should proceed to make payment for the tax payable by the due date. IRAS will issue the revised NOA and tax refunds by May 2020. If the company is paying the tax by instalments, it should also continue with the payment schedule in the original instalment plan. The revised instalment plan will be issued to the company by May 2020. Companies may view their revised NOA at myTax Portal. Find more information here.

    (ii) Automatic Extension of Instalment Plan for Estimated Chargeable Income (ECI) 

    Companies that are on GIRO and filed their ECI on time (i.e. within three months from the end of their financial year) (i.e. qualifying companies) will automatically qualify for an additional two months of interest-free instalment, if the ECI is filed as follows:

    a. during the period from 19 Feb 2020 to 31 Dec 2020 (both dates inclusive); or
    b. before 19 Feb 2020 and the company has an ongoing instalment payment to be made in Mar 2020. 

    Qualifying companies who have filed their ECI before 19 Feb 2020 and have ongoing instalment payments to be made in Mar 2020 can expect to receive a letter from IRAS by 5 Mar 2020 on the automatic two months extension of the instalment plan. Companies can also view their revised instalment plan at myTax Portal from 5 Mar 2020. Find more information here.

    2. e-Filing of Estimated Chargeable Income (ECI) 

    Companies with financial year ending in Dec 2019 are required to e-File the YA 2020 Estimated Chargeable Income (ECI) by 31 Mar 2020 (i.e. within 3 months from the financial year end of 31 Dec 2019), unless the waiver to file ECI applies.

    Before you can e-File the ECI at, you need to be granted with either:
    • "Access to all e-Services" in CorpPass; or
    • "Approver" role for the "Corporate Tax (Filing and Applications)" e-Service in CorpPass.
