A complete guide for taxpayers in Singapore to understand the key filing deadlines, differences between paper filing and e-Filing, and how to avoid late penalties while maximising tax compliance.
📌 Why Tax Filing Deadlines Matter
In Singapore, meeting your personal income tax filing deadlines is crucial to avoid penalties, interest charges, and legal consequences. Whether you are a salaried employee, self-employed, or have multiple income sources, the Inland Revenue Authority of Singapore (IRAS) sets specific dates for paper filing and e-Filing.
Understanding the differences and planning ahead ensures you stay compliant and stress-free during the Year of Assessment (YA).
📅 Key Filing Deadlines for YA 2025
- Paper Filing Deadline: 15 April 2025
- e-Filing Deadline: 18 April 2025
These deadlines apply to most individual taxpayers. If you miss these dates, IRAS may issue a late filing penalty starting from SGD 200, which can go up to SGD 1,000 or more for prolonged delays.

📢 Final Thoughts
Whether you choose paper filing or e-Filing, the most important thing is to meet your Singapore income tax filing deadlines. Missing these deadlines can result in penalties, interest, and unnecessary stress.
For most taxpayers, e-Filing offers convenience, speed, and a few extra days to prepare. However, ensure that all details are correct before submission, as errors can still delay processing.
