Tax investigation involves the inspection of the tax declaration of a taxpayer who is suspected of tax evasion. In Singapore, it is performed by the Inland Revenue Authority of Singapore (IRAS).
IRAS tax investigation can be emotionally, psychologically and financially stressful because of the heavy penalties and imprisonment if one is found guilty of tax evasion or negligence. It is usually triggered by IRAS’ internal information or an informer. An informer can be rewarded handsomely by IRAS (i.e. 15% of tax recovered capped at $100,000) for providing reliable information and this makes it attractive for ex-business partners or disgruntled employees to report any incorrect tax filing to the IRAS.
Unlike desk audit or field audit where prior notice is given to the taxpayer, tax investigation usually comes as a surprise visit at the taxpayer’s office & residence, accountant’s office and/or other relevant premises simultaneously. During the raid, the IRAS investigators or officers gather all relevant documents and the computer forensic experts “clone” the computer records to preserve the necessary evidence for prosecution in court. The cash in taxpayer’s safe deposit box may be counted and recorded for off-the-books cash transactions.
After the raid, IRAS investigators willl interview all parties involved (i.e. suppliers, customers, employees, etc), record statements and gather more evidence from different sources in addition to the evidence gathered during the raid. Taxpayer who has wrongfully reported the income or expenses can either be charged in court or settled out-of-court.

What to do when you are under tax investigation in Singapore?
It is natural for anyone to be worried when IRAS raided their premises. No matter what happens, please give the tax investigators your cooperation and do not obstruct them from performing their duties as it is an offence to do so under the law. The tax investigators may ask questions or record statements during the raid. If you are sure of the answers, you can tell them on the spot. If you are unsure or unable to recall, you have the right to confirm with them later. It is extremely important that you are absolutely sure before you confirm because any inconsistency in your answers may work against you later.
After the raid or visit by IRAS, it is critical that you appoint a tax professional who is experienced in handling tax investigation cases because such cases are complex and require the right support in order to effectively mitigate the detrimental consequences of non-compliance and resolve the issues with IRAS. You should not risk engaging an inexperienced tax agent and jeopardizing your chances of resolving it out-of-court.
