The Inland Revenue Authority of Singapore (IRAS) has concluded its Goods and Services Tax (GST) audit activities for the 2022/2023 period, recovering a significant $162 million in outstanding taxes and penalties.

The extensive audit programme covered a wide range of industries, resulting in the completion of 2,521 GST audits. To enhance compliance awareness and deter common errors, IRAS has published selected anonymized case studies and detailed information on its compliance initiatives on its official website.

These published cases are intended to serve as practical guidance for GST-registered businesses, illustrating frequent pitfalls and enabling proactive correction through voluntary disclosures. The key areas of non-compliance identified include:

  1. Incorrect GST Treatment of Netted Supplies: Errors involving the misapplication of GST rules to transactions involving counter-supplies or barter trade, where the net value was incorrectly used instead of the gross value for GST accounting.
  2. Failure to Account for GST on Reverse Charge Supplies: Omissions in applying the reverse charge mechanism, where GST-registered businesses in Singapore failed to self-account for GST on services procured from overseas suppliers not registered for GST in Singapore.
  3. Insufficient Documentation for Input Tax Claims: Failure to produce valid tax invoices or other mandatory supporting documentation required to substantiate claims for input tax on business purchases.
  4. Fictitious Input Tax Claims: Submission of claims for input tax on purchases that were either not made, not supported by valid documentation, or not incurred for business purposes.

“The recovery of $162 million underscores the effectiveness of IRAS’s audit programme and the persistent nature of certain GST compliance gaps,” stated a tax compliance expert familiar with the findings. “The publication of these specific case types provides clear direction for businesses to review their own processes, particularly concerning complex areas like reverse charge and inter-company transactions.”

IRAS emphasizes that businesses discovering similar errors in their own GST filings should make voluntary disclosures promptly. Proactive disclosure may result in reduced penalties.
