Error in Filing Taxes in Singapore: Penalties, Corrections & How to Avoid Costly Mistakes
Filing taxes accurately is essential for both individuals and businesses in Singapore. Errors in tax submissions can lead to financial penalties, audits, or even legal consequences. Understanding what happens when mistakes occur—and how to fix them—can save you time, money, and stress.
What Happens If You Make an Error in Tax Filing?
Mistakes in tax returns can arise from incorrect calculations, omitted income, or misunderstanding tax regulations. In Singapore, the Inland Revenue Authority of Singapore (IRAS) takes such errors seriously and may impose penalties depending on the nature of the mistake.
- Errors Without Intent to Evade Taxes
If the mistake was accidental or due to negligence:
- Penalty of up to 200% of the tax underpaid
- Fine of up to $5,000
- Possible imprisonment of up to 3 years
- Errors With Intent to Evade Taxes
If there is evidence of deliberate tax evasion:
- Penalty of up to 400% of the tax underpaid
- Fine of up to $50,000
- Possible imprisonment of up to 5 years or more
IRAS evaluates each case based on factors such as compliance history, level of negligence, and cooperation during audits.
Can You Correct a Tax Filing Error?
Yes. Singapore’s tax system allows taxpayers to rectify mistakes.
Filing an Objection to Notice of Assessment (NOA)
If you disagree with your tax assessment:
- Submit an objection via myTax Portal
- Do so within 2 months of receiving the NOA
- Tax must still be paid first, even while the objection is under review
Reduce Penalties with Voluntary Disclosure
If you discover an error, it is always better to act early.
Under IRAS’ Voluntary Disclosure Programme (VDP):
- No penalty if errors are disclosed within 1 year of the filing deadline
- Reduced penalties (as low as 5%) for late disclosures
- Must be accurate, complete, and voluntary before IRAS initiates an audit
This approach shows good faith and significantly reduces legal and financial consequences.
Common Causes of Tax Filing Errors
Businesses and individuals often make mistakes due to:
- Poor record-keeping
- Misclassification of expenses
- Omitted income
- Lack of understanding of tax rules
- Manual calculation errors
IRAS may treat repeated mistakes or poor compliance history as aggravating factors when determining penalties.
