Companies will be issued either a Form C-S or Form C notification letter based on IRAS’ records. If your company receives the Form C notification letter but qualifies for Form C-S, you may proceed to log in to mytax.iras.gov.sg to e-File Form C-S.
If your company did not receive the letter by 1 Jun 2021, you can still log in to mytax.iras.gov.sg to e-File Form C-S/ C. Before you start e-Filing, please ensure that you are authorised in Corppass. For assistance on Corppass setup, please refer to the Step-by-Step Guides.
For assistance on how to e-File, please refer to the User
Guides (under “File Form C-S” or “File Form C”).
