A Singapore company can sit idle for months, hold no sales, and have no employees, but that does not automatically stop its filing obligations. So, do dormant companies file taxes? Usually, yes, unless the company has received formal approval from IRAS to stop filing corporate income tax returns.
This is where many directors get caught out. “Dormant” is not a universal pass from tax, ACRA, or GST compliance. The correct action depends on whether the company is dormant for tax purposes, whether it remains GST-registered, and whether it has received a filing waiver.
Do dormant companies file taxes in Singapore?
A dormant Singapore company generally must continue filing its corporate income tax return if IRAS sends it a Notice to File. A nil return may be required even where there was no revenue, no trading activity, and no profit during the financial year.
For IRAS purposes, a company is generally dormant when it does not carry on a business and does not receive income. However, the position is not always as simple as having no customer invoices. Interest earned on a bank account, rental income, dividends, investment gains, or other receipts can mean the company is not dormant for tax purposes.
If IRAS has issued a notice to file Form C-S, Form C-S Lite, or Form C, file it by the deadline unless IRAS has approved a waiver. Ignoring the notice because the company is inactive can lead to late filing penalties, estimated assessments, and unnecessary follow-up work.
A dormant company may be able to stop filing tax returns
IRAS may grant a waiver from filing corporate income tax returns to a dormant company. This is useful for a company that has genuinely stopped business activity and does not expect to restart soon.
The company must apply for the waiver. Do not assume it applies automatically. IRAS will consider the company’s facts, including whether it has ceased business, whether it has income or assets generating income, and whether there is an intention to resume operations. A company that plans to restart shortly, retain investments, or receive passive income may not be suitable for a waiver.
Once a waiver is approved, the company generally does not need to file income tax returns for the dormant period. If business resumes later, the company must inform IRAS and restart its tax filing obligations.
Tax dormancy and ACRA dormancy are not the same
Directors often use the word “dormant” to mean “not trading.” That is a useful business description, but it is not enough for compliance purposes.
IRAS focuses on whether the company carries on business or receives income. ACRA and the Companies Act use a different test for dormancy, centered on accounting transactions. A company can therefore appear inactive in day-to-day operations but still have transactions that matter for statutory reporting, such as bank charges, professional fees, loan movements, or investment activity.
This difference matters because an income tax filing waiver from IRAS does not remove ACRA obligations. Likewise, an exemption or simplified treatment for financial statements does not mean the company can ignore its tax position.
When in doubt, review the company’s bank statements, invoices, contracts, investments, loans, and expenses for the financial year. A short review before the filing deadline is much cheaper than correcting an incorrect dormant declaration later.
Annual returns still need attention
A dormant company that remains on the Singapore register normally still needs to file an annual return with ACRA. Being inactive does not, by itself, remove this requirement.
For most private companies, the annual return deadline is generally within seven months after the financial year end. The company may also need to prepare financial statements unless it qualifies for an applicable exemption. The exact requirement depends on the company’s status, its transactions, and whether it meets the conditions for relief.
An annual return is separate from the corporate income tax return. One is filed with ACRA, while the other is filed with IRAS. Completing one does not satisfy the other.
If the company has no realistic plan to trade again, keeping it open simply because it might be useful one day can become expensive. Even a dormant company can incur recurring costs for corporate secretarial work, registered address services, annual return filing, and tax compliance. In that situation, striking off may be a more practical option than maintaining an inactive entity year after year.
What about Estimated Chargeable Income?
Estimated Chargeable Income, or ECI, is another filing point that directors should check. Companies generally file ECI within three months after the end of their financial year, unless they qualify for an exemption.
A dormant company with no revenue and no chargeable income may qualify not to file ECI. However, the exemption should be confirmed against the company’s actual position rather than assumed. For example, a company that received investment income or earned bank interest may need a different treatment.
Even if no ECI is required, IRAS may still require the company to file its corporate income tax return later unless a tax filing waiver has been granted. ECI exemption and tax return waiver are different matters.
GST-registered dormant companies must keep filing
GST is one of the most common compliance traps for inactive businesses. If a company remains GST-registered, it generally must continue submitting GST returns for each prescribed accounting period, even if every figure is zero.
A nil GST return is still a return. Failure to submit it can lead to penalties or estimated assessments. There is no automatic pause in GST reporting simply because the business has stopped selling.
If the company has ceased making taxable supplies and does not intend to restart, it may be appropriate to apply for GST deregistration. The company should first consider practical issues, including outstanding GST obligations, assets held at deregistration, and whether it expects to resume taxable business soon. Deregistering and re-registering later can create extra administration, so the decision should match the company’s real business plans.
A practical checklist for an inactive company
Before treating a company as dormant, directors should confirm these points:
- No trading, service income, rental income, interest income, or investment income was received during the period.
- Any Notice to File from IRAS has been reviewed and answered by the stated deadline.
- ECI requirements have been checked after the financial year end.
- The annual return and financial statement requirements have been reviewed separately from tax filings.
- GST returns continue to be submitted if the company is still GST-registered.
- The company has a clear decision: retain it for a future purpose, apply for a tax filing waiver, or consider striking it off.
Keeping clear records is especially useful for foreign-owned companies. Overseas shareholders and directors may assume that no local sales means no Singapore filing obligations. But the company’s place of incorporation and registration status still create compliance responsibilities in Singapore.
When retaining a dormant company makes sense
There are valid reasons to keep a company dormant. A founder may be holding the entity for a future project, preserving a company name, waiting for funding, or keeping a structure ready for a planned market entry. In these cases, ongoing compliance may be worthwhile.
The trade-off is simple: the company should remain properly maintained. It needs a registered office, corporate records, annual return attention, and the correct tax and GST filings or waivers. A dormant company is low-maintenance, not no-maintenance.
If operations have stopped permanently, striking off can reduce future cost and paperwork. But it should be done only after outstanding liabilities, tax matters, bank accounts, and statutory filings have been dealt with. An incomplete strike-off process can delay closure and create more work for directors.
A quick review of your company’s activity, registration status, and future plans can prevent avoidable penalties.
