3. Penalty for Late Filing — Section 234F
| Total Income | Late Fee |
|---|---|
| Up to ₹5,00,000 | ₹1,000 |
| Above ₹5,00,000 | ₹5,000 |
| Below basic exemption limit (voluntary filing) | Nil |
Additionally, interest at 1% per month applies on outstanding tax under Section 234A from the due date.
4. What is a Belated Return?
A belated return under Section 139(4) is filed after the original due date (31st July 2026 for most) but before 31st December 2026. Disadvantages of belated returns:
- Late filing fee of ₹1,000–₹5,000 under Section 234F
- Interest on unpaid tax under Section 234A
- Cannot carry forward most losses — business losses, capital losses permanently lost
- Cannot opt for old tax regime if you have business income
5. What is a Revised Return?
A revised return under Section 139(5) corrects mistakes in the original ITR. You can revise as many times as needed before 31st December 2026. Can only be filed if the original was filed on time. Common reasons: missed income, wrong deduction, incorrect bank account, wrong ITR form.
6. Consequences of Not Filing ITR
- Cannot claim TDS refund
- All losses for FY 2025-26 permanently lost — cannot be carried forward
- Scrutiny notices from Income Tax Department's Non-Filer Monitoring System (NMS)
- Higher TDS at 20% on specified transactions
- Penalty up to ₹5,000 and in wilful cases prosecution with imprisonment
7. ITR-U — Updated Return (2-Year Window)
Missed even the belated return deadline? File an Updated Return (ITR-U) under Section 139(8A) within 2 years from the end of the assessment year — i.e., up to 31st March 2029 for FY 2025-26.
| When Filed | Additional Tax |
|---|---|
| Within 12 months of AY end (by March 2027) | 25% of additional tax + interest |
| Between 12–24 months of AY end (by March 2028) | 50% of additional tax + interest |
ITR-U cannot be used to claim refunds — only to declare additional income or correct omissions.
