Reporting Tax Evasion or Fraud

Tax evasion is when someone has deliberately provided IRAS with inaccurate or incomplete information about their activities to reduce their tax liability or obtain undue tax credits and refunds.

Examples of evasion in Income Tax:

• failing to declare all assessable income
• claiming deductions for expenses that were not incurred or were not legally deductible
• claiming personal relief on fictitious dependents

Examples of evasion in GST:

• claiming input tax on fictitious purchases
• omitting output tax charged on local taxable supplies
• claiming tourist refunds when not entitled to

Some signs that a person or business may be evading income tax:

• keeping two sets of accounts
• providing false invoices to support fictitious expenses
• not wanting to issue a receipt

Some signs that a person or business may be evading GST:

• keeping two sets of accounts
• providing false invoices to support fictitious expenses or purchases
• providing false export documents to support zero-rated supplies of goods
• giving false information on customers and suppliers
• not wanting to issue a receipt or a tax invoice

However, not all people or businesses who show these signs are deliberately evading tax. By telling us what you know, we can investigate the matter to find out truth and take actions against those who have committed tax offences

What We Do With Your Information

We take every report of tax evasion seriously and will make an independent evaluation of the case using the information provided as well as other information available to us. Where we decide that an investigation is warranted, we will follow up accordingly. Please note that IRAS is bound by strict secrecy provisions. Thus, we will not be able to update you on how we deal with the information provided including; whether we have decided to commence investigation and the status or outcome of the case in the event that we have investigated the case.

IRAS will not handle matters which are not related to tax evasion, e.g. personal or internal disputes among business partners, commercial disputes between private parties.

You may request for a reward in relation to the information and/or documents you have provided. A reward of 15% computed based on tax recovered and capped at $100,000, can be given only if the information and/or documents you provided have led to the recovery of tax that would otherwise have been lost.

To be considered for a reward, you will need to state clearly that you are requesting for a reward and provide your name and contact details at the point when making the tax evasion report. We may request you to come to IRAS subsequently for identity verification. You will need to provide relevant and specific information with supporting documents or evidence showing tax evasion.

All reward payments are made solely at the discretion of the Commissioner of Inland Revenue, after the investigation has completed and taxes are collected. At that point, IRAS will contact those informants who are to be rewarded. IRAS will not update the status of any reward requested or provide any updates on the status of investigated cases.
