Steps to File Form C-S (Lite)

 

Form C-S (Lite) Step 1

Before you begin to e-File your Form C-S (Lite), you should prepare the company's tax computation and supporting schedules. You can refer to our webpage on Preparing a Tax Computation and Basic Corporate Tax Calculator for information on how to prepare the company's tax computation.

Companies filing Form C-S (Lite) are not required to submit their financial statements and tax computations. Companies should however prepare these documents and be ready to submit them in the event that IRAS requests for them.

Once you have your tax computation and supporting schedules ready, proceed to Step 2. 

Form C-S (Lite) Step 2

Does your company meet all the following conditions?

  1. The company is incorporated in Singapore;
  2. The company has an annual revenue1 of $200,000 or below;
  3. The company only derives income taxable at the prevailing corporate tax rate of 17%2; and
  4. The company is not claiming any of the following in the YA:
    1. Carry-back of Current Year Capital Allowances/ Losses
    2. Group Relief
    3. Investment Allowance
    4. Foreign Tax Credit and Tax Deducted at Source

1 Revenue refers to the main income source of the company excluding separate source income, such as interest.
2 Form C-S (Lite) should not be filed if the company derives income that is tax exempt or taxed at concessionary tax rates, such as where tax incentives are granted. The exceptions to the "no exempt income" condition are where a company derives:
(i) One-tier tax exempt Singapore dividends, and/ or
(ii) Specified foreign-sourced income exempted from tax under S13(8) of the Income Tax Act.

If your company meets all the conditions above, proceed to Step 3. Otherwise, refer to our webpage to determine if your company should file Form C-S or Form C.

  • My company qualifies to file Form C-S (Lite). Can I choose to file Form C-S or Form C instead?

    Yes. Companies that qualify to file Form C-S (Lite) can still choose to file Form C-S or Form C.

  • I have already e-Filed Form C-S for YA 2020. Do I need to e-File another Form C-S (Lite) if my company meets the qualifying conditions for Form C-S (Lite)?

    No. Companies that have already e-Filed their Form C-S for YA 2020 are not required to re-file using the Form C-S (Lite) for YA 2020.
