Received an IRAS “Red Letter”? What Singapore SMEs Should Do

Received an IRAS "Red Letter"? Here's What Singapore SMEs Should Do

You open a letter from IRAS and see that your company needs to take action.

The first reaction is usually simple:

“How serious is this?”

“Red letter” is not an official term used by the Inland Revenue Authority of Singapore (IRAS). Businesses commonly use it to describe certain tax-related notices, including estimated tax assessments, late-payment notices, composition offers, agent-appointment notices or court summons.

Receiving one does not automatically mean your company is being prosecuted.

But it does mean something needs your attention.

The notice will usually tell you what is outstanding, what action is required and when you need to respond. Ignoring it can allow a relatively manageable tax issue to develop into something much more expensive.

For a Singapore SME, that can mean more than paying a penalty.

Why Would IRAS Contact Your Business?

There are several reasons a company may receive an IRAS notice.

Common issues include:

• Estimated Chargeable Income (ECI) was not filed
• The Corporate Income Tax Return was filed late or not filed
• A GST return remains outstanding
• GST was declared but not paid
• IRAS raised an estimated assessment that remains unpaid
• A composition amount or previous notice was ignored
• Errors or omissions were identified in a tax return

These situations do not all carry the same consequences.

A missed ECI filing, for example, can lead to an estimated Notice of Assessment. A late GST return can trigger an immediate $200 penalty and additional penalties while the return remains outstanding. An unpaid tax balance can eventually lead to recovery action.

The First Problem: You Didn't File Your ECI

Estimated Chargeable Income, or ECI, is one of the first corporate tax obligations a company needs to keep track of after its financial year ends.

Generally, companies must file their ECI within three months from the end of their financial year, unless they qualify for an ECI filing waiver or fall within a category that is specifically not required to file.

There is an important exemption for smaller companies.

A company does not need to file ECI for a particular Year of Assessment when both conditions are met:

• Annual revenue is $5 million or below; and
• ECI is nil.

If only one condition is met, the company still needs to file.

For example, a company with $4 million in revenue but $100,000 ECI must still file. Likewise, a company with $8 million in revenue and nil ECI must still file

What happens when ECI isn't filled?

This is where the situation can become uncomfortable.

If a company is required to file ECI but does not do so within the deadline, IRAS may issue an estimated Notice of Assessment based on previous years' income or other information available to IRAS.

If an estimated assessment is issued, the company generally has to:

Pay the estimated tax within one month from the date of the Notice of Assessment.

Instalment payment is not available for this estimated assessment.

If the company disagrees with the assessment, it can generally file an objection within two months from the date of the Notice of Assessment. However, the objection does not suspend the payment obligation. The estimated tax still needs to be paid while the objection is being reviewed. Any excess payment can subsequently be refunded if the assessment is revised.

One important distinction

Unlike late GST filing, IRAS' ECI guidance does not set out a standard monthly late-filing fee specifically for ECI.

The bigger immediate risks are:

• An estimated assessment
• A one-month payment deadline
• Late-payment penalties if the tax remains unpaid
• Potential enforcement action

That makes ECI something businesses should monitor before the deadline rather than waiting for an IRAS notice.

Your ECI Was Filed But Your Corporate Tax Return Wasn't

ECI is not the same thing as your company's final Corporate Income Tax Return.

Your company must also file the appropriate Form C-S, Form C-S (Lite) or Form C, generally by 30 November each year.

This is where some businesses make a costly assumption:

“We already filed our ECI, so our tax filing is done.”

It isn't. The Corporate Income Tax Return is a separate filing obligation. If it is filed late or not filed at all, IRAS may take several actions, including:

• Issue an estimated Notice of Assessment
• Offer the company a composition amount
• Require a director to provide outstanding information
• Summon the company or its directors to court

IRAS states that the composition amount can be up to $5,000 per offence, depending on the company's compliance history.

What if the company ignores the issue for even longer?

The consequences can escalate.

If tax returns remain unfiled for two years or more, the company may receive a summons to attend court.

If convicted, the company may be ordered to pay:

• A penalty equal to twice the amount of tax assessed; and
• A fine of up to $5,000 for each offence.

Failure to attend court can also result in further legal action, potentially including a warrant of arrest against the company director.

The important takeaway: paying a composition amount is not a substitute for filing the outstanding return.

GST Creates a Different Kind of Deadline

For GST-registered businesses, the issue can become even more immediate because filing and payment are recurring obligations.

A GST-registered business generally needs to submit its GST return and pay the tax due within one month after the end of each accounting period.

And even if there were no transactions during the period, the business still needs to file a NIL GST return.

So what happens if the GST return is missed?

The penalty starts immediately

For an outstanding GST F5 or F8 return, IRAS may impose:

This means a business cannot simply think:

“We'll file it when we have time.”

Every additional month that the return remains outstanding can increase the penalty.

What If You Filed the GST Return but Didn't Pay?

This is a different problem.

Your business may have filed the GST return correctly but still be unable to pay the amount declared.

For unpaid GST, IRAS may impose a 5% late-payment penalty.

If the tax remains unpaid after the applicable 60-day period, an additional 2% penalty per month may be imposed, subject to a maximum of 50% of the outstanding tax.

For example, if your business has $10,000 of unpaid GST:

Original GST: $10,000

Initial 5% penalty: $500

Additional 2% monthly penalty: $200 per applicable month

So the debt can increase even though the original GST amount has not changed.

What Should You Do If an IRAS Notice Arrives?

Don't wait for a second reminder.

The faster you understand the issue, the more options you may have to resolve it before it escalates.

Step 1: Verify the notice

Check your company's information and outstanding balance through myTax Portal.

Make sure you understand exactly what IRAS is asking for.

Step 2: Identify the problem

Is the notice related to:

• ECI?
• Corporate Income Tax?
• GST filing?
• GST payment?
• An estimated assessment?
• A composition amount?
• An agent appointment?
• A court summons?

The answer determines what you should do next.

Step 3: File anything that is outstanding

If a return has not been filed, submit it as soon as possible.

This remains important even if the company cannot immediately pay the full tax amount.

For certain situations, IRAS will only review or revise an estimated assessment after the outstanding return and supporting documents have been submitted.

Step 4: Review any estimated assessment

If IRAS has estimated your taxable income and you believe the amount is incorrect, review the assessment carefully.

For an ECI estimated assessment, an objection generally needs to be submitted within two months from the date of the Notice of Assessment. Remember that the objection does not suspend the requirement to pay the estimated tax.

Step 5: Deal with the payment issue

If tax and penalties are outstanding, settle them according to the instructions provided by IRAS.

If the company is experiencing cash-flow difficulties, contact IRAS promptly to understand what payment arrangements may be available rather than simply allowing the debt to remain unpaid.
