📌 What is a Late Payment Penalty?
A late payment penalty is an additional charge imposed when you fail to pay your taxes by the stipulated due date. This applies to Income Tax, Property Tax, GST, and Corporate Tax in Singapore. The penalty is meant to encourage timely compliance and ensure government revenue collection.
💰 Late Payment Penalty Rates in 2025
As of 2025, IRAS imposes the following penalties:
- Initial Penalty: 5% of the unpaid tax immediately after the due date.
- Additional Penalty: 1% of the unpaid tax for each completed month after the due date, up to a maximum of 12%.
This means the maximum penalty can be 17% of the outstanding tax if left unpaid for more than a year.
📊 Example Calculation
Let’s say you owe S$10,000 in income tax:
- Missed payment deadline → 5% penalty = S$500
- 3 months late → 3% additional penalty = S$300
- Total penalty after 3 months: S$800
⚠️ Consequences of Not Paying
- Additional interest and penalties
- Bank account or salary garnishment
- Seizure of property and assets
- Legal proceedings and possible prosecution
✅ How to Avoid Late Payment Penalties
- Set up GIRO payments – Spread payments into 12 interest-free monthly instalments.
- Pay early – Make payments before the due date to avoid system delays.
- Use the correct payment method – Pay via internet banking, AXS, or PayNow QR.
- Track due dates – Enable IRAS email/SMS reminders.
- Request an extension – If facing financial difficulties, contact IRAS early for a payment arrangement.
