What is a GST ASK review?

Businesses filing GST for the first time or have just registered for GST can self-assess their GST submissions with GST Assisted Self-Help Kit (ASK) to identify past GST errors and improve their GST filings. Self-help kits can be adopted by GST-registered traders voluntarily. Additionally, conducting ASK is a mandatory requirement when applying for or renewing Major Exporter Scheme (MES), Import GST Deferment Scheme (IGDS), Approved Third Party Logistics Company Scheme (A3PLCS) or any of the GST schemes.

When can one file their GST return?

GST returns are due one month after the end of the accounting period covered by the return. GIRO deductions are made on the 15th of the month following the due date for GST payments if you are on the GIRO plan.

However, please take note that late GST returns and payments will result in penalties. Therefore, it is important that a GST-registered business needs to monitor its transactions and plan its resources to submit its GST returns on time.

What are the benefits of adopting GST ASK?

The benefits of GST-registered businesses adopting GST ASK are:

  1. Ensure GST submissions are accurate.
  2. Find previous GST errors beforehand so you can disclose them to IRAS timely and receive lowered or zero penalties.
  3. Satisfy requirements for application or renewal of GST schemes like MES, IGDS or A3PLCS.
  4. Understand the GST filing and record-keeping requirements.
  5. Reduce the risk of incurring penalties for errors.
  6. Receive administrative concessions for common errors communicated during the annual review of ASK.
What documents are needed for the ASK annual review?

The key documents needed for an ASK annual review are as follows:

  1. a) GST ASK templates which can be found on the IRAS website.
  2. b) GST F5 monthly or quarterly declarations.
  3. b) Purchases and Sales listings for the selected financial period under review.
  4. c) Source accounting documents and records supporting all GST declarations for the period under review.
  5. d) Annual Financial Statements or latest Management Accounts for the financial year under review.
What are some examples of errors encountered in ASK reviews?

Some common errors include:

  1. Exempt supplies did not include realised exchange losses or gains and proceeds from the issuance of shares.
  2. Insufficient documents maintained to support zero-rating of supplies.
  3. There was no GST charged on the disposition of fixed assets, such as motor vehicles.
  4. Incorrectly reporting supplies that are out of scope as zero-rated supplies.
  5. GST was not charged on the sale of scraps or by-products.
  6. Claiming GST input tax on disallowed items like upkeep of motor vehicle expenses and medical expenses.

Failure to apply the correct GST treatment and to file accurate GST returns can result in significant penalties and possible jail sentences for serious cases. The GST laws and regulations must be understood by the preparer, and the reviewer (if any) of GST returns should keep abreast of GST developments in addition to training its personnel.
