IRAS said it conducts regular audit programmes to detect anomalous GST refund claims and ensure they comply with the rules.
In 2025, more than 1,300 businesses making GST refund claims were audited, uncovering various forms of non-compliance, including incorrect GST filings and unsupported refund claims, it said.
These audits resulted in a recovery of more than S$100 million in taxes and penalties.
