About Corporate Tax Filing in Singapore
Corporate Tax e-Filing
Every company in Singapore is required to submit its Corporate Income Tax Return to IRAS electronically, using either Form C or Form C-S.
Submission Deadline
The due date for filing is 30 November each year. No extensions are permitted.
Assessment Year (YA)
The tax filing is based on income earned during the previous financial year.
