📅 Standard Tax Filing Deadlines in Singapore
- E-Filing: 18 April 2025
- Paper Filing: 15 April 2025
These dates apply to individual taxpayers. Corporate tax deadlines differ and are based on the company’s financial year-end.
⚠️ What Happens If You Miss the Filing Deadline?
Failing to submit your tax return on time can trigger several consequences under Singapore tax law:
- Late Filing Penalty Notice – IRAS will issue a warning and a monetary penalty for late submission.
- Estimated Notice of Assessment (NOA) – IRAS may estimate your income and tax payable without your actual return.
- Late Payment Penalty – If you also fail to pay on time, an additional 5% late payment penalty applies, plus 1% monthly thereafter (up to 12%).
- Summons to Court – Persistent non-compliance may result in prosecution, fines, or imprisonment.
💰 Late Filing Penalties (2025)
| Filing Delay | Penalty Amount |
|---|---|
| 1 – 3 months late | Up to S$200 |

| More than 6 months | Up to S$1,000 or Court Action |
