IRAS takes actions and imposes penalties on taxpayers who evade tax and/or file incorrect tax returns. When there is no evidence of wilful intention to evade taxes, IRAS will take into consideration the circumstances under which the errors were made in determining the penalties. IRAS will also waive penalties for taxpayers who voluntarily disclose any errors and meet the qualifying conditions for the waiver.

Penalties for errors in tax returns

Under the Income Tax Act 1947, taxpayers may face the following consequences for filing an incorrect return:

Without reasonable excuse or through negligence

  1. Penalty up to 200% of the amount of tax undercharged;
  2. Fine up to $5,000; and/or
  3. Imprisonment up to three years

With wilful intention to evade taxes

  1. Penalty up to 400% of the amount of tax undercharged;
  2. Fine up to $50,000; and/or
  3. Imprisonment up to five years

IRAS will notify taxpayers of the penalty amount and due date for payment of penalty. IRAS will also explain the reason for imposing the penalty.

Consideration of "circumstances under which errors were made"

For cases where there is no evidence of any wilful intention to evade taxes, IRAS will decide on the penalties for incorrect returns by considering the circumstances under which errors were made.

Circumstance #1: Negligence / Without reasonable excuse

Possible indicators of negligent behaviour include:

  • Taxpayer has committed an offence on the same issue or a similar issue; 
  • Taxpayer has received prior information from IRAS or advice from his tax agents informing him of the correct tax treatment; 
  • Taxpayer has good knowledge of tax laws (e.g. taxpayer is a tax agent / accountant) but submits an incorrect tax declaration; or
  • Taxpayer does not keep proper records and accounts of his business transactions

Circumstance #2: Compliance history

Bad compliance history is an aggravating factor when IRAS decides on the penalty for the tax offences. IRAS will consider the nature and frequency of non-compliance made in the past such as:  

  • late payment of taxes due;
  • late filing of Estimated Chargeable Income (ECI);
  • late filing of tax return; and
  • previous omission of income, giving of incorrect information or wrongful claim of relief / expense.

Circumstance #3: Cooperation during audits

Being uncooperative during an audit is an aggravating factor that IRAS will take into consideration when deciding on the penalty for the tax offences. A taxpayer is considered to be uncooperative when:

  • Taxpayer does not respond to audit queries in a timely manner and has no reasonable excuse for the delayed response; or
  • Taxpayer delays the progress of the audit with no reasonable excuse or obstructs the progress of the audit.

Circumstance #4: Commitment to future compliance

IRAS operates on the belief that taxpayers are generally compliant. Whether the taxpayer is committed to improving their tax compliance going forward is a mitigating factor which IRAS will take into consideration when deciding on the penalty for the tax offences.

Taxpayers can show their commitment to better tax compliance in the future by undertaking to improve their record keeping, using proper accounting software and/or engaging suitably qualified person to prepare their accounts, etc.

Voluntary disclosure of errors for reduced penalties

To encourage voluntary disclosures of past errors and omissions, IRAS may reduce penalties for voluntary disclosures which meet the qualifying conditions under IRAS' Voluntary Disclosure Programme. Learn more about how to make a voluntary disclosure.

For Income Tax, penalty waiver is granted for voluntary disclosures made within a 'grace period' of one year from the statutory filing date. After the lapse of the 'grace period', IRAS will impose a reduced penalty of 5% for every back year the disclosure was untimely, on an incremental basis.

Example 1: Rental omission in YA 2022

Taxpayer omitted to declare rental income received in 2021. He voluntarily disclosed the omission to IRAS on 1 Apr 2023. Assuming he has met all the qualifying conditions under the Voluntary Disclosure Program, the penalty will be as follows:

  • Since taxpayer came forward during the grace period of 16 Apr 2022 to 15 Apr 2023, IRAS will grant a one-time waiver of penalty.
  • If taxpayer makes the disclosure after 15 Apr 2023 but before 16 Apr 2024, the penalty would be 5% of the tax undercharged.

Example 2: Rental omission in YA 2020

Taxpayer omitted to declare rental income received in 2019. He voluntarily disclosed the omission to IRAS on 1 Apr 2023. Assuming he has met all the qualifying conditions under the Voluntary Disclosure Program, the penalty treatment is as follows:

16 Apr 2020 to 15 Apr 202116 Apr 2021 to 15 Apr 202216 Apr 2022 to 15 Apr 2023
Grace period 0%5%10%
If the taxpayer had come forward during the grace period of 16 Apr 2020 to 15 Apr 2021, he would have been entitled to a one-time waiver of penalty. However, because the disclosure was untimely, IRAS will impose a penalty of 10% of the tax undercharged.

If the taxpayer makes the disclosure after 15 Apr 2023 but before 16 Apr 2024, the penalty would be 15% of the tax undercharged.
