How to file

You may file your company's ECI:

• electronically via myTax Portal; or
• by completing and submitting an ECI Form.

To encourage you to e-File, the number of instalments you get for e-Filing your company's ECI is more than that for paper-filing.

With effect from Year of Assessment (YA) 2008, the number of instalments allowed to e-Filers and paper-filers of ECI are as follows:

• For e-Filers, e-File by the 26^th of each qualifying month to enjoy the maximum number of instalments allowable for that month.
• For paper-filers, your ECI Form should reach us by the 24^th of each qualifying month to enjoy the maximum number of instalments allowable for that month.

Example: December year-end company

If your company qualifies for instalments and has previously paid its tax by instalments, the instalment plan will be sent to your company together with your Notice of Assessment (NOA). However, if your company has not paid its tax by instalment previously, or your company is filing ECI for the first time, instalments will not be given automatically. In this case, if you wish to pay your tax by instalment, you will need to request for the instalment plan.

• Please inform us of your preference to pay tax by instalments before you file your ECI. You can email us at ctpayment@iras.gov.sg or contact us at telephone number 1800 356 8622.
• For e-filers, if we update your request for instalments before you e-File, the instalment plan will be sent to your company together with the NOA after you e-File.
• For paper filers, you need to complete and submit the ECI Form (with request for payment by instalments).

  i.e. Form IRIN322. Please note that to enjoy the maximum number of instalments allowable for each qualifying month, this form must reach us by the 24^th of that month.

• If you wish to pay by GIRO, you must complete and submit GIRO Application Form. 
• Please note that companies that are not registered in Singapore do not qualify for payments by instalments.

For more details on payment, refer to How to pay.

Things to note when you declare ECI amount

• The amount of ECI declared must be before the deduction of the exempt amount under partial tax exemption or tax exemption scheme for new start-up companies. We will automatically allow the appropriate exempt amount. 
• If your ECI amount is nil (e.g. your company is in a loss position or it is dormant and has no income), you must declare "0" ECI amount.
• If you are claiming unutilised losses, capital allowances or donations brought forward from previous YA, your ECI amount must take into account the unutilised losses, capital allowances, or donations claimed.
• If you are claiming loss items under Group Relief System, the ECI amount must take into account the loss items transferred or claimed under group relief.
• If there is a claim for tax deducted at source on franked dividends, the ECI amount filled in must be the regrossed amount calculated based on the net tax payable after deducting the tax deducted at source on franked dividends. For an example on how to calculate regrossed ECI amount, refer to the Explanatory Notes to ECI Form.
• The first row, with the pre-filled prevailing corporate tax rate, is for you to fill in your ECI amount to be taxed at the prevailing corporate tax rate.
• The second row is for you to fill in ECI amount to be taxed at a concessionary tax rate of 10%. You do not need to fill in "0" in the second row if your company does not have any income to be taxed at the concessionary rate of 10%. That is, the box in the second row must be blank if the tax rate of 10% is not applicable.
• The third row is for you to fill in income to be taxed at any other rate, which is different from the pre-filled prevailing corporate tax rate or 10%. You do not need to complete the third row if your company does not have any income to be taxed at a rate other than the prevailing corporate tax rate or 10%. That is, the third row must be blank if it is not applicable.

e-Filing of ECI

You can e-File ECI to us if you have been authorised as an "Approver" for "Corporate tax matters" by your company.

Any staff or director of the company, or a third party (e.g. tax agent), can be authorised as an "Approver" for "Corporate tax matters" via e-Services Authorisation System (EASY) using the company's e-Services Access Code.

For more details on EASY, please refer to user guide for EASY.

After the authorisation via EASY, the authorised person can e-File for the company via myTax Portal using his personal SingPass or IRAS PIN.

You will receive an acknowledgement statement upon successful submission of the ECI.

Filing ECI using ECI Form

Besides e-Filing, you can also file ECI by completing and submitting an ECI Form. However, please note that the number of instalments given for paper filing is lesser than that for e-Filing.

There are three types of ECI Forms:

• ECI Form (for company)
• ECI Form (with request for payment by instalments)
• ECI Form (for tax agent)

You can download the relevant ECI Form at Estimated Chargeable Income (ECI) Forms.
You can also request for a fax copy of the ECI Form by using the self-help options at the Corporate Tax Integrated Phone Service 1800-356 8622.
