What is a Dormant Company

A dormant company is one that does not carry on business and has no income for the whole of the basis period. For example, if your company did not carry on business and had no income for the whole of the basis period ending in year 2024, it is regarded as a dormant company for the Year of Assessment (YA) 2025.

A dormant company must file its Corporate Income Tax Return (Form C-S/ Form C-S (Lite)/ Form C) by 30 Nov every year unless the company has been granted a waiver to file Form C-S/ Form C-S (Lite)/ Form C.

How to File Form C-S/ Form C-S (Lite)/ Form C for Dormant Companies

You may file a simplified Income Tax Return, "Form C-S/ Form C-S (Lite)/ Form C for your dormant company" by completing only two essential fields (takes approximately 5 minutes) using the File Form for Dormant Company digital service at mytax.iras.gov.sg. You are not required to submit your dormant company’s financial statements to IRAS.

Example

It may use the File Form C-S/ C for Dormant Company digital service at mytax.iras.gov.sg to do so.

Step 1

Do the following before you start filing:

  • Ensure that you are duly authorised by your company as an 'Approver' for Corporate Tax (Filing and Applications) in Corppass. View our step-by-step guides for assistance on Corppass setup.
  • Have your Singpass as well as your company’s Unique Entity Number (UEN)/ Entity ID.

Applying for a Waiver to File Form C-S/ Form C-S (Lite)/ Form C

Your dormant company can apply to IRAS to be released from the requirement to file its Form C-S/ Form C-S (Lite)/ Form C if it satisfies the following qualifying conditions:

  1. It must be dormant and must have filed its Form C-S/ Form C-S (Lite)/ Form C, financial statements and tax computation(s) up to the date of cessation of business.
  2. It must not own any investments (e.g. shares, real properties, fixed deposits). If the company owns investments, it must not derive any income from these investments.
  3. It must have been de-registered for Goods and Services Tax (GST) purposes prior to this application if it had previously been a GST-registered company.
  4. It must not have the intention to recommence business within the next 2 years.

How to Apply

Step 1

Apply for the waiver for your dormant company via the Apply for Waiver/ File last Form C-S/ C (Dormant/ Striking Off) digital service (formerly known as Apply for Waiver to Submit Tax Return (Dormant Company)) at mytax.iras.gov.sg. From 1 Oct 2021, IRAS no longer accepts the hardcopy application.

Step 2

After the waiver application, your dormant company will have 21 days from the date of the waiver application to file its Form C-S/ Form C-S (Lite)/ Form C for advance Years of Assessment, financial statements and tax computations (where applicable) using the File Form C-S/ Form C-S (Lite)/ Form C digital service at mytax.iras.gov.sg, failing which, the waiver application will be rejected.

Example

Company B with a 31 Dec financial year end ceased business on 31 Mar 2025 and wishes to apply for the waiver to file its Form C-S/ Form C-S (Lite)/ Form C in Aug 2025. As the business ceased on 31 Mar 2025, Company B needs to file Form C-S/ Form C-S (Lite)/ Form C for the following YAs:

  • YA 2025 for basis period: 1 Jan 2024 to 31 Dec 2024
  • YA 2026 for basis period: 1 Jan 2025 to 31 Mar 2025

As at May 2025, the File Form C-S/ Form C-S (Lite)/ Form C digital services are available up to YA 2025.

However, Company B will be able to file its YA 2026 Form C-S/ Form C-S (Lite)/ Form C if it applies for the waiver to file Form C-S/ Form C-S (Lite)/ Form C using the Apply for Waiver/ File last Form C-S/ C (Dormant/ Striking Off) digital service. It will then be given 21 days from the date of the waiver application to file the YA 2026 Form C-S/ Form C-S (Lite)/ Form C, failing which, the waiver application will be rejected.

Specific Circumstances to Apply for Waiver in Writing

These companies may write to IRAS with the following details:

  • Business cessation date in dd/mm/yyyy format

Recommencing Business

Once your dormant company recommences business or starts to receive any income, you have to notify IRAS within 1 month from the date of commencement of business or earning/ receiving the income by filing out the form for Recommencement of Business to request for the Form C-S/ Form C-S (Lite)/ Form C. Please have the following information ready as you prepare to fill in the above form:

  • Name of requestor and Unique Entity Number (UEN) of the company
  • Valid email address and contact number
  • Date of recommencement of business OR the date of receipt of other source(s) of income (e.g. interest, dividend, rent), whichever is earlier
  • Only if applicable, the new principal activity and the effective date of change, together with a copy of your business profile extracted from the Accounting and Corporate Regulatory Authority (ACRA) BizFile+ portal

It is an offence if a company fails to inform IRAS when it has recommenced business or started to receive income. IRAS will not hesitate to take strong actions against companies and its directors who deliberately avoid or assist their companies to avoid the obligations to file their Corporate Income Tax Returns.

FAQs

  1. My company is dormant but is GST-registered. Can I still apply for a waiver to file Form C-S/ Form C-S (Lite)/ Form C for my company?

    Your company needs to cancel its GST registration before applying for a waiver to file Form C-S/ Form C-S (Lite)/ Form C.

  2. My company is newly incorporated and has been dormant since incorporation. It has not filed any Form C-S/ Form C-S (Lite)/ Form C. Can the company apply for a waiver to file Form C-S/ Form C-S (Lite)/ Form C?

    Yes, your company can apply for a waiver if it is likely to remain dormant for at least the next 2 years.

  3. Can I view the letter approving the waiver to file Form C-S/ Form C-S (Lite)/ Form C at mytax.iras.gov.sg?

    Yes, a softcopy of the letter is available at mytax.iras.gov.sg under the View Notices/ Letters - Corporate Tax digital service.

  4. Do I need to apply for the waiver to file Form C-S/ Form C-S (Lite)/ Form C on a yearly basis, if my company continues to be dormant?

    Once your company has been granted a waiver from a specific date, it will not be issued with Form C-S/ Form C-S (Lite)/ Form C from that date onwards. Hence, your company does not need to submit the waiver application on a yearly basis to IRAS.

  5. My company was granted a waiver to file Form C-S/ Form C-S (Lite)/ Form C previously, but the company received income this year. What do I need to do?

    If your company recommences business or receives any income after being granted a waiver, you have to notify IRAS within 1 month from the date of commencement of business or earning/ receiving the income. See Recommencing Business for more details.

    However, if the income received is a one-off transaction and your company continues to be dormant, you may submit a letter to IRAS explaining as such and attach the company's financial statements and tax computation for that relevant Year of Assessment (YA) with the letter.

  6. Can my foreign company or my foreign company's Singapore branch apply for a waiver to file Form C?

    The waiver is not applicable to your foreign company or your foreign company's Singapore branch that is registered with the Accounting and Corporate Regulatory Authority (ACRA). You are required to notify ACRA once your entity ceases to carry on business in Singapore so that ACRA can remove the company/ branch from its register. This is in accordance to Section 377(1) of the Companies Act 1967.

    Once your foreign company or Singapore branch is removed from ACRA's register, IRAS will receive the information from ACRA and will not send any more Form C to your entity. However, your entity must file its Form C, financial statements and tax computation(s) up to the date of cessation of business so that its tax matters can be finalised up-to-date.

    Conversely, if your foreign company has been filing Form C but is not registered with ACRA, you may write to IRAS to ask for a waiver to file Form C with the following information:

    • Subject heading 'Cessation of business in Singapore'
    • Date of cessation of business in Singapore in dd/mm/yyyy format
    • Name and contact details of a person whom IRAS can liaise with on tax matters
    • Confirmation that the company does not hold any property and has not been in receipt of any other income in Singapore since the above-mentioned date
    • Confirmation that the company does not have intention to carry out future business activities in Singapore
    • Any outstanding Form C, financial statements and tax computation(s)
    • For advance YAs where the File Form C digital services are not yet available, financial statements and tax computations up to the date of cessation of business

  7. Do I need to file the company’s Estimated Chargeable Income (ECI) if the company has been granted a waiver to file Form C-S/ Form C-S (Lite)/ Form C?

    No. If your company has been granted a waiver, it need not file the ECI.

  8. My company owned investments (e.g. real properties, fixed deposits and foreign shares) during the year ending 30 Jun 2024. However, the company did not carry on business during the same period. Can my company complete the Form C-S/ Form C-S (Lite)/ Form C as a dormant company for YA 2025 if it only received interest income from the fixed deposits?

    No. As your company was in receipt of interest income in the financial year ending 30 Jun 2024, it is not regarded as a dormant company for YA 2025. Hence, it has to file its Form C-S/ Form C-S (Lite)/ Form C for YA 2025 using the File Form C-S/ Form C-S (Lite)/ Form C digital service at mytax.iras.gov.sg, and not the File Form for Dormant Company digital service.

Capital Allowances, Trade Losses & Donations for Dormant Companies

Your dormant company cannot claim capital allowances and deduction of expenses incurred in the basis period relating to the Year of Assessment (YA) in which it is dormant, as it is not carrying on a trade or business during that period.

However, unutilised losses brought forward from a previous YA, in which your company was not dormant, can be deducted against income for a subsequent YA if it satisfies the shareholding test.

Example

Company C has a 31 Dec financial year end and was dormant for the period from 1 Jan 2024 to 31 Dec 2024, which relates to YA 2025. Company C cannot claim capital allowances or deduction of expenses incurred from 1 Jan 2024 to 31 Dec 2024 in its YA 2025 Form C-S/ Form C-S (Lite)/ Form C. It can, however, bring forward unutilised losses that existed before YA 2025 to be utilised in future YAs (where it is no longer dormant), if it satisfies the shareholding test.

Your dormant company can make a claim for donations if the donations were made to an approved Institution of a Public Character (IPC) or to the Singapore Government for the benefit of the local community. However, you must file its Form C-S/ Form C-S (Lite)/ Form C using the File Form C-S/ Form C-S (Lite)/ Form C digital service instead of the File Form for Dormant Company digital service at mytax.iras.gov.sg.

Any unutilised donations arising from a YA can be carried forward to subsequent YAs, up to a maximum of 5 years and subject to your company satisfying the shareholding test.
