Explanatory Notes to Form C:
Please submit the Form C by the filing due date to avoid enforcement actions such as composition or summons issued to the company.
If your company was dormant and had previously been granted a waiver to submit Income Tax Return, but has now re-commenced business or is now in receipt of income, please complete and submit the Request for Income Tax Return Form (51KB) by post or by fax at 6351 4360.

Document Identification Number (DIN)
DIN is a unique number code that is generated by IRAS to identify each Income Tax Return (Form C-S/ C) issued.
DIN is to be entered in the DIN worksheet of the Form C which you have downloaded. When you enter the DIN, it will be automatically populated on page 1 of the Form C.
You can obtain DIN from the "View DIN" e-Service.
If DIN is not available, please email us at firstname.lastname@example.org.
* If the company meets the conditions for filing Form C-S, you can e-File Form C-S via mytax.iras.gov.sg from 2 Jun 2015 or download the softcopy of Form C-S.
The DIN is the same whether you paper file Form C-s or Form C.
