What is a dormant company in Singapore (and why definitions matter)

Understanding what ‘dormant’ means in law helps directors avoid surprise filings and penalties.

In everyday terms, a dormant company is one that has paused operations — no trading, no staff payroll and no supplier payments. The legal test matters more than the label because regulators check different signs when deciding compliance routes.

How dormancy typically happens

Dormancy often follows a newly incorporated entity that never starts trading, a pause during restructuring, or a deliberate stop to cut running costs.

That pause can look like no sales and no income. Yet a company can still post accounting entries that break inactivity under one regulator’s test.

Maintenance transactions that may still be allowed

Nominal payments such as company secretary fees and registered address charges
Statutory fees, filing penalties and small bank charges
Minimal corporate administration expenditures needed to preserve legal status

“Whether you can file a nil tax return or seek a waiver depends on how those transactions are recorded.”

ACRA vs IRAS criteria for dormancy in the present regulatory landscape

Two separate authorities look at company inactivity through distinct lenses: one checks accounting records, the other checks income. This difference drives which filings you must make in a given financial year.

ACRA’s accounting test and eligibility

ACRA treats a company as dormant when there are no accounting transactions recorded during the financial year, apart from limited maintenance items needed to keep the legal entity alive.

The corporate regulatory authority accepts small compliance-related payments, such as secretarial fees or registered address charges, without negating dormancy. Eligibility also typically requires that the company is not listed, not a listed subsidiary, and that total assets stay at or below S$500,000 at any point in the year.

IRAS’s income-based approach

The Inland Revenue Authority assesses dormancy by looking for revenue or income in the financial year. IRAS allows statutory expenses to exist without automatically breaking dormancy.

However, a company can pass ACRA’s accounting test yet still generate interest, rent or dividends that trigger inland revenue reporting. In such cases the revenue authority singapore may expect filings or a formal waiver.

“Meet both tests — the ledger and the receipts — before you treat the period as inactive.”

ACRA checks accounting entries and asset thresholds under the Companies Act.
IRAS checks income and may still request statements tax filings unless a waiver is granted.

Next: the following section explains what to file, who files it and the timelines that apply under each authority singapore.

tax obligations for dormant companies singapore: what you must file and when

When activity stops, the key question becomes which annual submissions still must be lodged and when.

Nil filing usually means e‑filing a corporate income tax return using IRAS’ “File Form for Dormant Company” e‑service. Use this if there is truly no income and only maintenance payments appear in the ledger.

When a waiver may be possible

IRAS may grant a waiver where a company is inactive, holds no investments and has no plan to transact in the next two years. Cancellation of goods services tax registration is expected before any waiver request.

Which return might arrive

Form C, Form C‑S or Form C‑S (Lite) are all corporate income tax returns. IRAS can still issue a notice; if so, either file the nil return or seek a waiver. Keep written evidence of dormancy until IRAS confirms an exemption.

Year mapping and carry‑forwards

The Year of Assessment maps to the prior financial year — pick the correct period to avoid misalignment. Unutilised losses may carry forward if the shareholding test is met, but capital allowances, trade losses and donations cannot be claimed for the period while inactive.

“File until IRAS confirms a waiver; do not assume silence equals exemption.”

Stop trading: confirm dormancy, cancel GST if registered, then file or apply for waiver.
If IRAS contacts you, respond promptly and supply supporting records.

ACRA annual return, financial statements and Companies Act exemptions for dormant companies

Silence in the accounts does not silence corporate deadlines; annual returns remain due. Even with little or no activity, a company must lodge its annual return with ACRA within seven months after the financial year end for private, non‑listed entities.

Deadlines and consequences

Missing the seven‑month date can trigger late fees, enforcement notices and possible summonses. Directors face compliance risk and rising costs if filings slip. Act early to avoid escalation.

When financial statements need not be prepared

Under section 201A of the Companies Act a company need not prepare financial statements if it is not listed or a listed subsidiary, has assets of S$500,000 or less at all times in the year, and has been inactive since the prior year‑end.

Simplified annual return routes

Eligible private entities may use BizFile+ to file a simplified annual return when information is unchanged and audited statements are not required. Filing may be performed by a director, the company secretary or a registered filing agent to reduce errors and ensure compliance.

“Exemption from preparing financial statements does not exempt you from filing the annual return.”

Check guidance and who needs to submit financial statements on ACRA’s site: file financial statements.

Ongoing corporate compliance even when the company is inactive

A company that looks inactive still needs active governance and basic services to stay in good standing.

Being ‘inactive’ does not mean unmanaged. Directors must keep statutory registers, maintain a reliable registered address and ensure officer particulars are current. These small tasks prevent missed notices and costly remedial work.

Secretary role and continuous oversight

Every company must appoint a company secretary within six months of incorporation. The secretary continues to schedule filings, prepare minutes and send reminders even when business activity is minimal.

Key records and the registered office

Keep the members, directors and charge registers updated. Maintain resolutions and a functioning registered address so regulators and banks can reach the entity promptly.

Task	Who	Suggested frequency	Why it matters
Company secretary duties	Secretary / outsourced agent	Ongoing	Ensures timely filings and governance
Statutory registers	Directors / secretary	Update within 14 days of change	Evidence of status and shareholding continuity
Registered office	Company / service provider	Keep live at all times	Receives regulator notices and legal documents

Practical services tip: Many entities outsource secretarial and accounting support to keep compliance low‑touch and predictable. This helps keep transactions limited to permitted maintenance and makes it easier to evidence inactivity if regulators enquire.

Adopt an operational checklist: note FYE, annual return due dates and filing windows, maintain CorpPass access, and update officer details promptly. Small actions now reduce compliance risk later and protect directors from avoidable breaches.

How to revive a dormant company and restart trading without surprises

Revival begins the moment the company resumes business activity or receives any income. At that instant, compliance duties switch back on and submission windows become immediate.

Notifying IRAS within one month

Act within 30 days. Notify iras by myTax Mail or email with the subject line: “Recommencement of business and request for Corporate Income Tax Return/Income Tax Return”.

Include company name, UEN, date of recommencement and date of any other income (interest, rent, dividends). Add the new principal activity and its effective date if it changed.

Attach an updated ACRA BizFile+ business profile when activity or description differs from records.

Requesting the correct return after recommencement

Once notified, the inland revenue authority may issue the suitable return: Form C‑S, Form C‑S (Lite) or the full Form C. Ask for the correct form promptly to avoid missed filing windows.

Practical requirements before filing

Shareholding continuity matters. Check that ownership changes do not break the shareholding test if you plan to claim carry‑forwards or reliefs.

Appoint an Approver with CorpPass access early so submissions can be authorised without delay.

Claimable items once filing resumes

Donations to approved institutions and other deductible items become claimable again when you file returns. Keep invoices, receipts and approval letters to support claims in the correct year of assessment.

“Notify within one month and prepare attachments before you start online sessions to avoid timeouts.”

Action	Who	Timing	Why
Notify revenue authority	Director / Secretary	Within 1 month of activity or income	Triggers issuance of correct income tax return
Attach updated ACRA profile	Secretary / Filing agent	At time of notification	Ensures principal activity is accurate on records
Appoint Approver (CorpPass)	Director / Admin	Before filing	Prevents access delays and submission failures

Conclusion

A low‑activity company may look simple to manage, but regulators still expect evidence and timely submissions.

Keep in mind that a dormant company can cut day‑to‑day cost and protect brand or IP, yet annual returns to ACRA and nil tax filings to IRAS usually continue unless a waiver applies.

Check facts: whether ledger entries or actual income occurred will decide the correct path. Confirm dormancy, confirm investment status, cancel GST if needed, and keep clear records of inactivity and intent.

If you resume trading, notify IRAS within one month and request the correct tax return to avoid penalties. If you will not use the entity again, consider striking off after settling liabilities and gaining member consent.

Small, structured governance protects directors, preserves future options and keeps the company in good standing. company support

FAQ

What is a dormant company under ACRA and why does the definition matter?

A dormant company for the Accounting and Corporate Regulatory Authority (ACRA) usually records no accounting transactions during its financial year, aside from limited maintenance items. The precise definition matters because ACRA and revenue authorities apply different tests; meeting ACRA’s dormancy rules may not exempt the entity from other filing duties with Inland Revenue Authority of Singapore (IRAS) or from Companies Act requirements.

How does a company become dormant in practice?

Dormancy typically occurs when a business ceases trading, earns no income and undertakes no significant transactions. Routine maintenance transactions such as paying annual filing fees, bank charges or holding meetings are often permitted without ending dormant status, but each regulator assesses activities against its own criteria.

What common maintenance transactions are usually allowed while remaining dormant?

Small administrative items like bank service fees, statutory filing fees, routine secretarial actions and preparation of minimal records are commonly accepted. Large or commercial transactions, issuing invoices, or receiving revenue will usually terminate dormant treatment for tax or corporate filing purposes.

How does IRAS define dormancy and how does this differ from ACRA?

IRAS focuses on revenue and taxable income: a company with no revenue or assessable income may be considered inactive for tax administration. In contrast, ACRA examines accounting transactions. A company can therefore be dormant under ACRA yet still trigger tax filings if IRAS identifies assessable income or statutory deductible expenses.

What should a dormant company file with IRAS and when?

Even if inactive, companies must attend to corporate income tax returns. IRAS provides a “File Form for Dormant Company” route for nil returns in many cases. Deadlines follow the Year of Assessment and financial year end, so companies must check their specific filing dates and respond to any notices.

When can a company apply for a filing waiver with IRAS?

A waiver may be available when a company has been dormant for the entire financial year and meets IRAS conditions. Applications require clear statements of inactivity, and IRAS will reject waivers if there is any income, expense giving rise to tax consequences, or inadequate documentation.

Which income tax form might a dormant company be asked to submit?

Depending on circumstances, companies may receive Form C-S (or Form C-S (Lite)) or the standard Form C. IRAS determines the appropriate form based on factors such as whether the company is small, has simple affairs, or maintains tax-exempt status; companies should follow the notice issued for their Year of Assessment.

How do Year of Assessment and financial year dates affect filings?

The Year of Assessment links assessable income to the following calendar year. Companies must match the correct financial year to the corresponding return period and submit filings by the dates specified by IRAS and ACRA to avoid penalties.

Can unutilised losses be carried forward while the company is inactive?

Carry-forward of unutilised losses may be possible, but restrictions and continuity of ownership tests apply. Periods of dormancy do not automatically eliminate carry-forward claims, but companies should maintain proper records and seek professional advice to preserve reliefs.

What are the Goods and Services Tax (GST) considerations for inactive firms?

If registered for GST, a company must account for tax on taxable supplies even when activity is low. Deregistration may be required if turnover falls below thresholds; ensure GST cancellation occurs before relying on any filing waivers to avoid liabilities.

Are dormant companies exempt from preparing financial statements under the Companies Act?

Some dormancy scenarios allow simplified accounting or exemptions from full financial statements, subject to Companies Act criteria. Eligibility often depends on size, activity and asset levels; directors must confirm compliance with statutory requirements before claiming any exemption.

What are the annual return filing rules with ACRA for dormant companies?

Dormant companies still face annual return deadlines after the financial year end. Filing late can attract penalties. ACRA’s BizFile+ platform provides submission routes, and some simplified returns exist for qualifying entities.

Does a dormant company still need a company secretary and statutory registers?

Yes. Corporate governance obligations remain: a company must have a company secretary, maintain statutory registers, and keep its registered address current. These duties support legal compliance even when trading has ceased.

How do I notify IRAS when the company resumes trading?

Notify IRAS promptly—usually within one month—via myTax Mail or an authorised email. Include the date of recommencement, nature of activities, and expected turnover. This ensures IRAS issues the correct corporate tax return and updates accounting treatment.

Which tax return should I file after recommencement of business?

After recommencement, IRAS will typically require the standard Form C or an appropriate Form C-S if eligibility remains. The company should advise IRAS of the change in status so the correct form and assessments are applied for the relevant Year of Assessment.

What practical checks help avoid surprises when reviving a company?

Confirm continuity of shareholding for reliefs, update statutory registers, reappoint any required officers, and ensure an approver or authorised signatory is in place. Reassess GST registration, review past filings and reconcile bank records before trading resumes.

Can donations or other deductible items be claimed after restarting filing?

Eligible donations and deductible expenses incurred once filing resumes may be claimed subject to prevailing rules. Keep supporting documentation and follow IRAS guidance on allowable deductions and the timing of claims.
