GST Assisted Self-Help Kit (ASK): IRAS’ Voluntary Disclosure Framework Before a GST Audit

Most Singapore GST-registered businesses only think about self-review when IRAS knocks. But there is a lighter-touch, IRAS-endorsed framework that is meant to be used long before that point, and in many cases must be used, not because a business is under an audit, but because it wants to apply for or renew a GST scheme. That framework is the Assisted Self-Help Kit, better known as ASK.

ASK is easy to confuse with the Assisted Compliance Assurance Programme (ACAP), which we covered in detail in IRAS Assisted Compliance Assurance Programme (ACAP): A Practical Guide to GST Self-Governance. The two schemes sit at very different points on IRAS’ compliance spectrum. ACAP is a rigorous, enterprise-risk-management-based certification typically pursued by large or complex GST-registered entities seeking a multi-year compliance rating. ASK is a lighter, more accessible self-assessment package aimed at ordinary GST-registered businesses, including newly registered ones and those applying for common GST schemes.

This article sets out what ASK actually is according to IRAS, who is expected to use it, what each of its three sections covers, how it connects to voluntary disclosure and reduced penalties, and how it fits around the routine GST F5/F7 filing cycle.

What Is the Assisted Self-Help Kit (ASK)?

According to the Inland Revenue Authority of Singapore (IRAS), ASK is a comprehensive self-assessment compliance package that helps businesses review the correctness of their GST submissions and discover past GST errors early, so that they qualify for reduced or zero penalties under IRAS’ Voluntary Disclosure Programme.

ASK is primarily built for businesses that have just registered for GST, are filing GST returns for the first time (see our guide on GST Registration in Singapore if you are not yet registered), or simply want a structured way to check their GST practices before something goes wrong. Unlike ACAP, there is no formal certification tier system and no requirement to build out an enterprise risk management framework. It is designed to be workable for a typical small or medium-sized GST-registered business using standard templates provided free of charge by IRAS.

Voluntary in General, Compulsory for Scheme Applications

This is the detail that most businesses miss. ASK is voluntary if a business simply wants to strengthen its own GST governance. However, IRAS explicitly requires ASK to be performed when a business is applying for, or renewing, any of the following GST schemes:

• Import GST Deferment Scheme (IGDS)
• Approved Marine Customer Scheme (AMCS)
• Approved Contract Manufacturer and Trader (ACMT) Scheme
• Approved Refiner and Consolidator Scheme (ARCS)
• Major Exporter Scheme (MES)
• Approved Import GST Suspension Scheme (AISS)
• Approved Third Party Logistics (3PL) Company Scheme
• Specialised Warehouse Scheme (SWS)

In other words, if your business is planning to apply for the Major Exporter Scheme to ease cash flow on imports, or is coming up for MES renewal, ASK is not optional homework. It is a mandatory gate you must pass through, with a formal declaration submitted to IRAS as part of the application or renewal.

The Three Sections of ASK: The Review Checklist Areas

IRAS structures ASK into three distinct sections. A business may adopt one, two, or all three, depending on its situation, though scheme applicants are generally expected to complete the ASK Annual Review specifically.

Section 1: GST Practices

This section helps a business put in place internal processes covering people, record-keeping, systems, internal controls and risk management, to support overall GST compliance. IRAS recommends this section for businesses planning to register for GST, and those that are newly registered. IRAS provides a downloadable GST Practices template and a step-by-step user guide to work through it.

Section 2: Pre-Filing Checklist

This section is a quality-check tool used before a GST return is actually submitted. It is recommended for businesses filing their first GST return, and for GST-registered businesses that have had a change in business arrangement or a change in the personnel handling GST. Running the Pre-Filing Checklist before you lodge a return is, in effect, a structured second pair of eyes over your own F5 submission.

Section 3: ASK Annual Review

This is the section most closely tied to scheme applications and voluntary disclosure. The ASK Annual Review helps a business perform a regular, retrospective review of past GST returns, specifically to detect errors early. It is recommended for all GST-registered businesses, not just first-time filers, and it is the section IRAS requires when a business is applying for or renewing one of the schemes listed above.

Critically, the ASK Annual Review must be performed, or certified, by an individual accredited with the Singapore Chartered Tax Professionals Limited (SCTP) as an Accredited Tax Advisor (GST) or Accredited Tax Practitioner (GST). This accredited reviewer can be an in-house staff member or an external party such as your corporate services or tax adviser, provided they hold the relevant SCTP accreditation and follow the certification procedures in IRAS’ ASK Annual Review Guide.

Step-by-Step: How a Business Actually Uses ASK

In practice, a GST-registered business preparing for a scheme application or renewal, or simply doing a periodic health check, works through ASK roughly as follows.

1. Identify the trigger. Confirm whether you are applying for or renewing a scheme (making ASK compulsory), or doing a voluntary governance review.
2. Select the relevant section(s). A first-time GST filer may start with GST Practices and the Pre-Filing Checklist. A scheme applicant will need to complete the ASK Annual Review.
3. Engage an accredited reviewer. Arrange for an SCTP-accredited ATA (GST) or ATP (GST), whether in-house or external, to perform or certify the ASK Annual Review.
4. Retrieve past GST returns. Use the “Retrieve GST Returns/Assessments for ASK Review” digital service on myTax Portal to pull the historical F5 (and any F7 amendment) data the review needs.
5. Work through the templates. Complete the relevant IRAS Excel templates, testing input tax claims, output tax treatment, exempt and zero-rated supplies, and record-keeping against the checklist areas.
6. Identify and quantify errors. Where the review uncovers past GST errors, work out the affected periods and the tax impact.
7. Disclose voluntarily. Submit the errors to IRAS under the Voluntary Disclosure Programme, ahead of any audit, to access reduced or zero penalties.
8. File the declaration forms. For scheme applications and renewals, submit both the ASK Declaration Form on Completing Annual Review and, where errors were found, the ASK Declaration Form on Voluntary Disclosure of Errors.
9. Correct through F5/F7. Depending on materiality and timing, correct errors through your next GST F5 return or via a formal F7 amendment for a closed period.

How ASK Connects to Voluntary Disclosure and Reduced Penalties

The single biggest practical benefit of ASK is timing. Errors found through your own ASK review, before IRAS opens an audit, are disclosed under the Voluntary Disclosure Programme, which offers considerably lighter treatment than errors uncovered during an active IRAS review. We have set out the mechanics of that programme, across both income tax and GST, in IRAS Voluntary Disclosure Programme: How Singapore Companies Can Correct Tax and GST Errors With Reduced Penalties, so we will not repeat the penalty mechanics here.

What is specific to ASK is that IRAS extends additional administrative concessions for certain common errors uncovered specifically through the course of an ASK Annual Review, on top of the general voluntary disclosure benefits. This is a meaningful incentive for a business to run the review proactively, rather than wait until it is compelled to as part of a scheme application.

ASK’s Relationship to the GST F5/F7 Filing Process

ASK does not replace your quarterly (or monthly) GST return filing obligations. It sits around that cycle in two ways.

First, prospectively, the Pre-Filing Checklist is meant to be used immediately before you submit a GST F5 return, catching coding and classification errors before they ever reach IRAS. Second, retrospectively, the ASK Annual Review looks back over returns you have already filed, and where it finds an error in a closed period, the correction is usually made through a GST F7 amendment for that period, alongside voluntary disclosure to IRAS. Businesses that discover an over-claim connected to an unpaid supplier invoice during this process should also check our guide on GST Bad Debt Relief in Singapore, a common area the ASK Annual Review touches on. For a fuller walkthrough of the standard filing workflow itself, see our guide on GST Return Filing in Singapore.

ASK vs ACAP: A Side-by-Side Comparison

Who Should Prioritise ASK Right Now?

Based on IRAS’ own guidance, ASK deserves priority attention if your business falls into any of these categories.

• You are newly GST-registered, or about to file your first GST return.
• You are planning to apply for, or are due to renew, the Major Exporter Scheme, Import GST Deferment Scheme, or any of the other schemes IRAS lists as requiring ASK.
• You have had a change in the personnel who prepare or review your GST returns.
• You have not reviewed your GST coding, exempt supplies treatment, or input tax claims in the past 12 months.
• You suspect there may be historical GST errors that have not yet been disclosed to IRAS.

If none of the above applies, and your business is instead a large group weighing up a formal multi-year GST governance certification, ACAP, rather than ASK, is the more relevant framework, and our earlier guide on ACAP is the better starting point.

Conclusion

ASK is often overlooked because it sits quietly beside its more heavyweight cousin, ACAP, and because businesses only think of “GST review” in the context of an audit letter. In reality, ASK is the framework most GST-registered SMEs in Singapore will actually encounter, whether because they are filing for the first time, tightening up their GST practices, or, most commonly, because they need to complete an ASK Annual Review to apply for or renew a scheme such as the Major Exporter Scheme. Used properly, it also opens the door to reduced or zero penalties under IRAS’ Voluntary Disclosure Programme for any past errors it uncovers.
