Effortless and punctual tax filing (Form C/C-S) facilitated by Timcole’s committed accountants.
Form C/C-S filing is obligatory
for Singapore companies.
- In Singapore, every company must electronically submit their Corporate Income Tax Returns through either Form C or Form C-S.
- The filing deadline is fixed on November 30 with no extensions granted.
- These tax returns pertain to income earned in the preceding financial year, known as the Year of Assessment (YA).
- Form C-S is intended for companies with annual revenue of $5 million or less, taxed at the standard corporate rate of 17%, and not seeking benefits like loss carry-back relief, group relief, investment allowance, or foreign tax credit. Other companies are required to use Form C and include their financial statements.

Basis Period and Year of Assessment (YA)
Your company is taxed on the income earned in the preceding financial year.
This means that income earned in the financial year 2020 will be taxed in 2021. In tax terms, 2021 is the Year of Assessment (YA), as it is the year in which your company’s income is assessed to tax.
To assess the amount of tax, IRAS looks at the income, expenses, etc. during the financial year. This financial year is known as the ‘basis period’.
The basis period is generally a 12-month period preceding the YA.
Consequences for late or non-filing of tax returns
Failure to file your Form C-S/ C together with financial statements and tax computation by the due date is an offence.
IRAS may take the following enforcement actions if you fail to file by the due date:
- Issue an estimated Notice of Assessment. You must pay the estimated tax within 1 month
- Offer to compound the offence
- Issue a Section 65B(3) notice to your company director to submit the required information in the Form C-S/ C to IRAS
- Summon the company or persons responsible for running of the company (including the directors) to Court

Can I request for an extension to file my company overdue tax return?
For current Year of Assessment
A request for extension to file may be made online via our Request Penalty Waiver/ Extension of Time to File digital service at mytax.iras.gov.sg.
However, if a summons to attend Court has been issued, filing extensions are not allowed. If you require an extension to file, your company representative/the director must attend Court on the Court date to appeal for an extension.
For previous Year(s) of Assessment
No filing extensions will be granted as the returns are long overdue
