GST Assisted Self-Help Kit (ASK) certification for the following

 - Major Exporter Scheme (MES) / IGDS / A3PLCS / AMCS / ACMT / ARCS

The Major Exporter Scheme (MES) is designed to alleviate the cash flow of companies that re-export a substantial amount of their imports. Under normal rules, businesses have to pay GST of the goods imported to Singapore Customs, and subsequently obtain a refund from IRAS after the submission of their GST returns. This can hinder cash flow for businesses that export goods substantially as no GST is collected from the zero-rated supplies to off-set their initial cash outflow on their imports. Companies approved under the MES can enjoy GST suspension for non-dutiable goods imported into Singapore, and on goods removed from a zero-GST warehouse.


To qualify for the MES scheme, the business must:

•    be GST-registered;
•    be active and financially solvent;
•    import goods for the purpose of the business;
•    make zero-rated supplies that account for more than 50% of the total supplies or the value of zero-rated supplies is more than S$10 million for a 12-month period;
•    maintain good internal controls and proper accounting records;
•    maintain good compliance records with Singapore Customs and IRAS; and
•    be able to comply with other such conditions as the Comptroller of GST may impose from time to time.

To apply for MES, the company must:- 

·         satisfy the qualifying conditions;

·         perform a self-review using the ASK methodology;

·         submit the application form F10 (application for MES) and the certified* ASK declaration form “ASK: Declaration Form on Completing Annual Review & Voluntary Disclosure of Errors”; and

·         submit a Letter of Confirmation & Undertaking where it imports or will import goods belonging to third parties, if applicable.

To renew the MES status, the company must:-
•    continue to satisfy the qualifying conditions for MES (see below);
•    perform a self-review using the Assisted Self-Help Kit (ASK) methodology; and
•    submit the renewal application Form R1 (application for Renewal of MES) and the certified* ASK declaration form “ASK: Declaration Form on Completing Annual Review & Voluntary Disclosure of Errors” to IRAS at least five months before the MES expiry date.


* The completed ASK declaration form must be certified by a tax professional (external or in-house who has been accredited by the Singapore Institute of Accredited Tax Professionals (SIATP) as an Accredited Tax Advisor (GST) or Accredited Tax Practitioner (GST).


If the requisite documents are not received by IRAS by the due date, the MES status will be cancelled and the company will have to pay GST on the imports. As it generally takes a few months to complete the ASK review, you may wish to start preparing for the ASK review early.

We also helped with the self review using the ASK if you are applying for the following GST schemes:

GST Assisted Compliance Assurance Programme (ACAP)

ACAP is a compliance initiative for businesses, who on a voluntary basis, conducts a holistic risk-based review to endorse the effectiveness of their GST controls. Inland Revenue Authority of Singapore(IRAS) introduced ACAP in 2011, in order for large businesses to have robust GST control framework. Presently, more than 300 companies have successfully applied for ACAP. ACAP reviews the sufficiency of management oversight and control activities present at Entity, Transactional and Reporting level for a selected 12 month period.Note : Review done over a period of 15 months.

We are qualified to be a ACAP reviewer because we hold the credential of Accredited Tax Advisor (Income Tax and GST).

ACAP's focus is on :

(1) Extensive reviews on Internal Controls that impact GST compliance (and)
(2) Verify transactions to ensure accuracy of GST reporting.
Note : The findings are consolidated and report submitted to IRAS.

Upon satisfactory completion of ACAP exercise, IRAS awards ACAP Status of either
(1) “Premium” for 5 years (>80% Controls Satisfied) (or)
(2) “Merit” for 3 years (>60% & <80% Controls Satisfied).

Benefits :

(1) GST Fines/Penalties avoided;

(2) Step Down IRAS GST Compliance Activities; 

(3) Dedicated Officers to handle GST Rulings and resolve GST issues expeditiously.

Already holding a valid ACAP status, you will not be required to submit ASK declaration form if:

◾ The Post ACAP Review (PAR) is performed; and

◾ The “PAR Declaration” form (GST F28) is submitted.

Successful ACAP applicants also are not required to submit the ASK declaration form pending the result of ACAP review and submission of ACAP Report. If they subsequently withdraw from participating in ACAP, businesses are then required to perform and submit the ASK declaration form within three months. Should they fail to obtain an ACAP status, there may be a requirement for submission of the ASK declaration form on a case-by-case basis.
