The “Zero Income” Myth: Why You Must File Tax Even If Your Singapore Company is Dormant

Last Updated: June 2026

Yes, a dormant company in Singapore still has to file. The common myth is that zero income means zero paperwork, but a dormant company must still file its annual return with ACRA and file its Corporate Income Tax Return with IRAS by 30 November every year, unless IRAS has granted it a waiver to file. Dormancy pauses your business activity, not your compliance calendar. The filings are lighter, though, and you can apply to IRAS for a waiver so you stop filing the income tax return altogether while the company sleeps.

This guide explains the two different definitions of dormant in Singapore (they are not the same), what a dormant company must still do, how the IRAS waiver works, and the choice between keeping a company dormant and striking it off.

Key Takeaways

• A dormant company still files: the annual return with ACRA, and the Corporate Income Tax Return with IRAS by 30 November, unless IRAS grants a waiver.
• ACRA dormant and IRAS dormant are different tests. ACRA looks at accounting transactions; IRAS looks at income.
• You can apply to IRAS for a waiver if the company is dormant, not GST registered, has no plans to recommence within 2 years, and has filed all outstanding returns and financial statements.
• Without a waiver, use the simplified File Form for Dormant Company service instead of the full return.
• A dormant company must still keep a company secretary and a registered address, and hold its AGM unless exempt.
• Reactivating is straightforward: notify IRAS and ACRA, then resume full filings once business recommences.

The “Zero Income” Myth: Dormant Does Not Mean Off the Hook

A dormant company is still a registered company. It keeps its incorporation, directors, company secretary, and registered address, so it keeps the duties that come with being on the register. What changes is the volume of filing, not whether you file at all.

Two regulators care about your company, and each runs its own check. The Accounting and Corporate Regulatory Authority (ACRA) governs your company’s existence and annual return. The Inland Revenue Authority of Singapore (IRAS) governs your tax. A company can be dormant for one and not the other, which is why the single word “dormant” causes so much confusion. Getting both definitions right is the foundation of clean accounting and compliance, and the first thing a good corporate secretarial team will check.

ACRA Dormant vs IRAS Dormant: Why the Two Definitions Differ

The two definitions test different things, so a company can satisfy one and fail the other.

What does ACRA dormant mean?

For ACRA, a company is dormant if there has been no accounting transaction during the financial period, apart from a short list of disregarded transactions (such as a subscriber taking shares in the constitution or certain statutory fees). If even one ordinary business transaction is recorded, the company is not dormant for ACRA that period.

What does IRAS dormant mean?

For IRAS, a company is dormant if it did not carry on business and had no income for the whole basis period. The IRAS guidance on dormant companies sets out this test. The focus is income, not the bookkeeping entries.

The practical gap is this: a company can have no income (IRAS dormant) yet still record accounting transactions such as paying its company secretary or a bank charge, which means it is not dormant for ACRA. Check your status against both tests separately rather than assuming one answer covers both.

What a Dormant Company Must Still Do

Even while dormant, the compliance baseline holds.

• File the annual return with ACRA. Every company files an annual return, including a dormant one. Where financial statements are required, they go in XBRL format unless an exemption applies.
• Hold the AGM, unless exempt. A dormant company holds its Annual General Meeting unless it qualifies for an exemption (private companies that send financial statements to members can be exempt, and dormant relevant companies may be exempt from preparing financial statements at all).
• Keep a company secretary. The requirement to appoint a company secretary does not pause for dormancy.
• Keep a registered office address. Your company must maintain a registered office address where official notices can be served.
• File the Corporate Income Tax Return by 30 November. Unless IRAS grants a waiver, the company files Form C-S, Form C-S (Lite), or Form C by 30 November, the same deadline as an active company.

Dormancy reduces the work but does not remove it. Missing these duties carries the same penalties as for an active company.

The Two Filing Paths with IRAS, Side by Side

The chart below contrasts what each regulator expects from a dormant company, so you can see why one status does not excuse the other.

The single most useful action a dormant company can take is to apply for the IRAS waiver, because it removes the annual income tax return while the company sleeps.

How Do I Apply for the IRAS Waiver to File a Tax Return?

If your company is genuinely dormant and likely to stay that way, you can apply to IRAS for a waiver to file. Once granted, you no longer file the annual Corporate Income Tax Return, which removes the heaviest recurring tax task.

To qualify, the company generally must meet all of the following:

• It is dormant and does not intend to recommence business within the next 2 years.
• It is not registered for GST. If it is GST registered, it should cancel the registration first.
• It has submitted its financial statements and tax returns up to the date business ceased.
• It owns no income-producing investments.

You apply through the digital service on IRAS myTax Portal. If granted, IRAS confirms that future returns are waived until the company recommences business. Keep that confirmation as proof no return is outstanding. If you are unsure whether you have settled every prior obligation, our guide on how to prepare for your financial year end helps you tie off the loose ends first.

What Is the File Form for Dormant Company Service?

If you do not have a waiver, or your application is still pending, you still have to file, but not the full corporate return. IRAS provides a simplified digital service called File Form for Dormant Company on myTax Portal. It is a stripped-down version of the income tax return designed for companies with no income, so the filing takes a few minutes rather than the effort of a full Form C.

In short, a dormant company sits in one of three states with IRAS: filing the simplified dormant form (no waiver), holding a waiver (no return needed), or recommencing and filing the full return again. The waiver is the lightest steady state.

Do Dormant Companies Need to File XBRL?

This trips up a lot of directors. A dormant company that is required to file financial statements generally files them in XBRL format, the same as an active company, unless it is exempt from preparing financial statements. Smaller and dormant companies may file a reduced set of XBRL information rather than the full template. The ACRA guidance on filing financial statements in XBRL format sets out which companies file what. The practical point: dormancy by itself does not remove the XBRL step. Being exempt from preparing financial statements does, so check that first.

Reactivating a Dormant Company

Bringing a company back to life is deliberately simple. When business recommences, you notify IRAS that the company is no longer dormant and resume filing the full Corporate Income Tax Return. Any waiver lapses, and the full annual return obligation returns on both the IRAS and ACRA side. There is no need to re-incorporate, which is a main reason directors choose dormancy over closure when a pause is temporary.

Keep It Dormant or Strike It Off?

The real decision is whether the company has a future. If you expect to trade again within a year or two, keeping it dormant preserves the entity, the name, and the incorporation date, at the modest cost of an annual return, a company secretary, and a registered address. If the company is finished for good, striking it off ends the recurring obligations entirely, though it has its own conditions (no assets, no liabilities, no outstanding filings, and IRAS tax clearance).

A quick rule of thumb: dormancy is a pause, strike off is a stop. Our guide on how to register a company in Singapore is a reminder of what an entity costs to maintain, and if the company has small-company audit relief, review the audit exemption criteria before deciding, since an audited dormant company costs more than an exempt one.

Frequently Asked Questions

Does a dormant company need to file tax in Singapore?

Yes. A dormant company must file its Corporate Income Tax Return (Form C-S, Form C-S Lite, or Form C) by 30 November each year, unless IRAS has granted it a waiver to file. Without a waiver, it can use the simplified File Form for Dormant Company service instead of the full return.

What is the difference between ACRA dormant and IRAS dormant?

ACRA treats a company as dormant if there has been no accounting transaction during the financial period. IRAS treats a company as dormant if it did not carry on business and had no income for the whole basis period. Because one test looks at bookkeeping and the other at income, a company can be dormant for one regulator and not the other.

Do dormant companies need to file annual returns?

Yes. A dormant company still files its annual return with ACRA, including financial statements in XBRL format where required, unless it is exempt from preparing financial statements. It also holds its AGM unless it qualifies for an AGM exemption.

How do I apply for the IRAS waiver to file a tax return?

Apply through IRAS myTax Portal once you meet the conditions: the company is dormant, does not intend to recommence within 2 years, is not GST registered, and has filed all outstanding returns and financial statements up to the date business ceased. If granted, the income tax return is waived until the company recommences business.

What is the File Form for Dormant Company service?

It is a simplified digital tax return on IRAS myTax Portal for dormant companies without a waiver. Because the company has no income, the form is much shorter than a full Form C, so the filing is quick while still meeting the 30 November obligation.

Can a dormant company be reactivated?

Yes. When business recommences, you notify IRAS and ACRA and resume filing full returns. Any IRAS waiver lapses on recommencement, and the company files as an active company again. There is no need to re-incorporate.
