e-Filing of Form C-S/ C

From YA 2020, e-Filing of the Corporate Income Tax Returns (Form C-S/ C) is compulsory for all companies.

Compulsory e-Filing of Form C-S/ C

From YA 2020, e-Filing of Form C-S/ C is compulsory for all companies.

In line with Government's direction for more cost effective delivery of public services and the Smart Nation vision to harness technology to enhance productivity, e-Filing of the Corporate Income Tax returns (including ECI and Form C-S/ C) is compulsory. A phased approach is adopted from Years of Assessment (YAs) 2018 to 2020 as follows:

 YA Target Group
 2018 onwards Companies with turnover more than $10 million in YA 2017
 2019 onwards Companies with turnover more than $1 million in YA 2018
 2020 onwards All companies

 

To e-File your Form C-S/ C, log into mytax.iras.gov.sg and obtain:

  • On-the-spot guidance as you e-File, with the iHelp facility
  • In-built formulae to auto-compute certain fields
  • An option to save draft until you are ready to submit
  • An estimated tax payable on-the-spot
  • An instant acknowledgement when you have successfully e-Filed

From YA 2018, to improve companies' e-Filing experience, the following amounts will be pre-filled:

  • Unutilised Capital Allowances brought forward
  • Unutilised Losses brought forward
  • Unutilised Donations brought forward
  • Current year Approved Donations
  • Unutilised Investment Allowances brought forward (applicable to Form C only)

The pre-filling is based on the carried forward amounts in the last assessment raised by IRAS for the immediate preceding YA. This will apply even if the assessment for the immediate preceding YA is under objection or query.

If the return for the immediate preceding YA is under review, the pre-filling will be based on the carried forward amounts declared in the Form C-S/ C of the immediate preceding YA.

The amounts are pre-filled for the companies' easy reference. You are advised to verify the accuracy of the information. In case of any discrepancy with the details (i.e. the companies' carried forward amounts in their own records differ from the pre-filled records), you may update the pre-filled sections in the relevant Boxes under "Company's Declaration" (with the exception of donations).

The 250% deduction for donations is granted based on information obtained from the Institute of Public Characters (IPCs). You can view details of the current year approved donation amounts in the “View Donations” e-Service.

If the company has made an Approved Donation, but it is not reflected in the “View Donations” e-Service at mytax.iras.gov.sg, it may be due to:

  1. Differences in receipting date - The IPC may have recorded your donation in a later financial period and a deduction would be accorded in the corresponding YA.
  2. You did not provide your company's Unique Entity Number (UEN) to the IPC. Please update your donation record with the IPC and IRAS will amend your assessment when we received the updated record.

If the company adopted a non-Singapore Dollar functional currency for the financial period and the Approved Donations are reflected in the “View Donations” e-Service at mytax.iras.gov.sg, please ensure that the “Functional Currency” in the Corporate Profile Page is updated accordingly. You will then be allowed to input a higher Singapore dollar equivalent amount of your current year donation in the “Company’s Declaration” box.
